3- order.
4              .This is a meeting of the ACRS Subcommittee on 5  Waste Managemeni.
6:              I am Dade Moeller, Chairman of the subcommitteo..
                  '7  The other ACRS members in attendance are Forrest Remick,                                                                    ,
8  Carson Mark,. Jesse Ebersole, and we anticipate the later                                                                  ,
9  arrival of William Kerr and Paul Showmon.
10              We have with us a team of consultants,= consisting-11  of Richard Foster, Martin Steindler, W.              Fauth and Melvin 12  Carter.
l()            13              The subcommittee will review various topics in 14  the high level and low level radioactive waste management 15  programs of the U.S. Nuclear Regulatory Commission, and the 16  subject of the salvaging of contaminated smelted alloys.
17              The first item this morning will be the last one 18  mentioned. The review of the standards and' policies for the                                                            ;
19  salvaging of contaminated smelted alloys.
20              With respect to this topic, there were several 21  items that I wanted to mention.              Commissioner Bernthal had 22  sent us a written request and, in fact, the Commission has
;                  23  endorsed or has requested that the ACRS address this i
i                  24  question, and he wanted us to look at this issue from the
()          25  standpoint of one, its broad range impacts or applications,
)                                                                                                                                                  i ACE. FEDERAL REPORTERS, INC.

(~')  DAVbw    1  particularly from a generic point of view, not just in te rms
  'J
  ~
2  of contaminated smelter alloys.
3              Number two, he wanted us to look at it in te rms 4  of its relationship to the disposal of contaminated 5  materials resulting from the decontamination and 6  decommissioning of nuclear power plants.
7              Thirdly, he wanted to know if we could address 8  its implications, not only with respect to health, but with 9  respect to industrial operations, particularly picking up 10  the EPA's call for more attention to its potential impacts 11  on the photographic industry or on the scientific 12  instrumentation industry or other industrial implications.
()          13              Fourth, he asked us to look at the alternatives
                  ! for the use of the end product.              For example, could DOE not 14 l 15 l recycle the materials within their own operations?                Could l
16 ' the materials not be recycled within perhaps the commercial 17  nuclear power industry?        Could the materials not be used in 18  high level waste repositories, not so much to be stored 19  there, but to be used in the structural equipment needed in 20  the respositories?
21              I also found myself asking a multitude of 22  questions, and I am sure everyone else has done the same.                I 23  was asking myself what are the alternatives, in terms of the 24  source term itself.        Of course, once the metal is smelted,
(~
(j)        25  the technetium is blended throughout the metal or within the ACE. FEDERAL REPORTERS, INC.

(
 
6300 01 03                                                                    4 DAVbw        metal, and there is very little hope from that point on of
(')s q
1 2    doing much in terms of decontamination.            And I needed to 3    hear a little more on the effort that was put into 4    decontaminating the metal before it was smelted, because, as 5    I understand, as the technetium originally was on the 6    outside of the metal, so why wasn't it cleaned of?            Of 7    course, that is a very difficult process.
8                Then you can further ask the question, looking at 9    this in terms of a specific problem, how important is it to 10    us in the future, if we don't reprocess our spent fuel from 11    nuclear power plants?        This only arises because of the 12    reprocessing, or it only arises because of the enrichment of
()          13    uranium claimed through reprocessing of spent fuel.
14                Several people that I was discussing this matter l
15 /  with said, well, even if we reprocess spent fuel, instead of I
16 I  putting the reclaimed uranium back into the gaseous I
i 17 !  diffusion enrichment process, why don't we set it aside and 18 l  enrich clean raw uranium and blend the two out over here I
19 l  somewhere?    Then you wouldn't have the technitium within 20    your gaseous dif fusion plant.
21                So the subject has ramifications and implications 22    far beyond its immediate appearance.
23                I asked myself, too, why don't they use the metal 24    to make nuclear submarines?            The NRC news release of March
()          25    14, 1986, said that federal guidance would be issued on ACE-FEDERAL REPORTERS, INC.

6300'01 04                                                                      5 l' this. Well then, the more I read, I gathered that the EPA
{  { DAVbw 2  is the'one that is responsible to develop the guidance, and 3  then one of the NRC memos -- I believe it was Dircks memo of            ,
4  November 25,    '85, had a draft letter in it, as I recall, 5  addressed to EPA, and it would have been about the third 6  letter to go to EPA, saying, we're ready to help develop 7  this guidance.
8              Well, I would like'to know where that guidance 9  stands. Of course, that is why the NRC Staff is here today, 10  hopefully to help us.
11              MR. EBERSOLE:        Where was that incident where the 12  metal came from Mexico?        How did that sneak out?          How was-()          13  that processed?
14              DR. MOELLER:      It is part of the same generic 15  problem. It certainly wasn't from the reprocessing.              It 16  wass a contaminated cobalt 60 thing.
17              Yes?
18              DR. PARRY:      It actually was a source that had 19  been inadvertently included in scrap.
20              DR. MOELLER:      I am saying it is kind of an 21  overall problem of recycling or having contaminated f.
22  materials out in the public domain.
j                23              MR. EBERSOLE:        You were talking about really i
24  gross removal of the surface, some surface fraction, before
()          25  the smelt it.

morning, but my understanding is that the technetium -- you 3    see, when you extract uranium and plutonium in a chemical 4    processing plant and separate it from the fission products, 5    the technetium goes with the uranium.            It is not a clean 6    separation or, you know, some of it goes in the uranium.
7    When you take that depleted uranium and put it back into the 8    gaseous diffusion plants to re-enrich it, you spread 9    technetium throughout the gaseous diffusion plant.            Then 10    when you replace components and so forth within the 11    diffurlon plant, you spread the technetium around.
12                Now the reason they smelt discarded components O)
(            13 l  from the gaseous diffusion plant, the reason they smelt 14    them is that they are in configurations that are classifiede 15    and they don't want people to see them in these shapes and
            . 16    forms, so they smelt it, so you won't recognize it.
17                DR. MARK:      Another cost-benefit for 18    classification.
19                Do they really recirculate the depoted uranium 20    very much?
21                DR. MOELLER:      I don't know.      Maybe when we talk 22    to the Staff, Don Hopkins may be able to help us.
I 23                MR. EBERSOLE:        Isn't gaseous diffusion going into 24    history anyway?

1  are questions that I would like to see answered, but if we (7q) DAVbw 2  look at it in its broader implications, that becomes less 3  important.
4                DR. SHEWMON:      If the plants go into history, this 5  will be more important than every before, because we've got 6  to decide what to do with it.
7                DR. MOELLER:      Our goal on this will be, if we can 8  do it, to develop and make some recommendations, as a 9  subcommittee, to send on up to the full committee to see if 10  the full committee is willing to take a position on it and 11  make some recommendations.
12                So I think we are in a position to give it an
(            13  objective review and see if we can offer some constructive 14  ideas.
15                Jack?
,              16                DR. PARRY:      I would like to mention that I think 17  that this is part of the generic question about de minimius I
18  as part of the Low Level Waste Policy Act, and it is 19  included, even peripherally in the mixed waste question that 20  the Commission is also facing.
21                Respectfully, I'd suggest that the subcommittee 22  may start considering or thinking about de mimimia.          That is 23  going to be a question that will arise fr-, the Savannah 24  River Plant's decontamination of their sludges, and so 25  forth, and a question that is going to be coming across ACE-FEDERAt.

  '(    DAVbw'    I  more'and more.
2              DR. MOELLER:      Okay.        Then the second item we will-3  cover today is reviewing the waste management research 4  program within NRC.      And in particular, we want to be 5  brought up on the implications and.the impacts of the Low 6  Level Waste Policy Act of.1985.              The committee,      I' hope, will 7  hear or at least maybe we can schedule a discussion of this 8  at the upcoming full committee meeting, because I don't 9  think the ACRS, as a body, as yet recognized that there are
                - 10t low level waste questions and problems for us to address as 11  a result of this Low Level Waste Policy Act.
12              I think there are considerable questions and
()            13  problems to be addressed.
14              Now supplementing the discussion of the Low Level.
15  Waste Policy Act, there are-two items.              The first one wo 16  must address in.this meeting.and the second one, again, I 17  hope we can begin to address.            The one we must address is 18  that on May 9, the RSK from the Federal Republic of Germany 19  will be here, a representative group, and they want to 20  discuss with the ACRS certain questions, three questions,
: 21. related to high level and low level waste management.                    I 22  have draf ted some written comments on each of these three 23  questions which will shortly be distributed or distributed 24  at the appropriate time.        They are done in a hurry.              They
()          25  are not complete.      They are probably not even accurate, but ACE FEDERAL REPORTERS, INC.

(    ) DAVbw    1  they will serve the basis for formulating some thoughts on 2  each item.
3                Here are the three questions.
4                How do the release limits and the dose limits and 5  the associated risk for a high level waste repository 6  compare to that of a low level waste repository and how does 7  that compare to a nuclear power plant or other types of 8  nuclear facilities?
9                MR. EBERSOLE:        Boy, that is potent!
10                DR. MOELLER:      Well, I have answered it in my 11  written response.
12                (Laughter.)
(~h
(_)          13                DR. SHEWMON:      Is this a comparison of risk to 14  both?
15                DR. MOELLER:      A little bit of everything.
16                What are the release limits?        What are the dose 17  limits?  And how do they compare riskwise?          And I even threw I
18  in there, which I didn't address -- I threw in uranium mill 19  tailings. I think it would be fun to look at them and see 20  how they compare.
21                DR. MARK:      Aren't the limits for high level 22  and low level actually different?
23                DR. MOELLER:      Yes, and they are formulated in a 24  different way.

2              DR. MARK:  By two different branches.
3              DR. MOELLER:  And we have to talk about it, you 4  know. If we can just be sure we know what the existing 5  situation is.
6              DR. STEINDLER:  Did you leave out, for example, 7  hazardous chemicals?
8              DR. MOELLER:  We didn't consider that.
9              You were saying this would be a thick document.
10  Frachlo said do it in six pages, which made my job easy.
11              DR. SHERMON:  We ought to put a little 12  technetium in that r                13              MR. ERERSOLE:  This is going to be a classic and 14  system integration.
15              DR. MOELLER:  The second question is, how do you i
16  evaluate the performance of a high level waste repository 17  and a low level waste disposal facility?    If you use models, 18  how are they evaluated?    How are they confirmed?  How are 19  they validated?
20              We are going to talk about that tomorrow, so we 21  will have some input there.
22              And the third cuestion was, what are the 23  environmental radiation surveillance requirements for a high 24  level waste and a low level waste facility?    Are they

11                                                                                                  DR. MOELLER:      These questions are questions by 12                                the RSK that we have agreed we would discuss on May.9th in
()                          13                                  the full committee meeting.
14                                                                                                  MR. EBERSOLE:        At whom would you point them in 15                                  real life, these questions?                                                                Congress?    NRC?
16                                                                                                  DR. MOELLER:      Yes.      EPA, NRC, DOE. We all have 17                                  to know the answers.
18                                                                                                  The second item under waste management that wo 19                                want to begin to discuss today is one that Jesse Ebersolo 20                                has laid on our platter, and that is to try to develop a 21                                statement on risk perspective, in terms of a high level 22                                waste repository.                                                            In other words, how does it compare to 23                                other nuclear facilities?
24                                                                                                  I think what Jesse was trying to do was to have a

2    in understanding the difference in the nature of the risks 3    associated with the high level waste respository versus a 4    nuclear power plant.
5                Now I prepared a quick draft of generalities on 6    this subject.
7                Jack Parry, then, did a much more detailed --
8    although he called it a qualitative asessment, he did some 9    very good quantitative assessments within his statement.
10    That has been distributed.
11                And then, since Jack pointed          .ut some errors in 12    mine -- you have not seen it?            Am I wrong that Jack Parry's (n),
13    thing has not been distributed?
14                DR. PARRY:    It went to the subcommittee.
15 g              DR. MOELLER:    We will run it off and see that ou 16 l  get it.
17                We will distribute it at noon, say.
18 i So after Jack showed me the errors in my 19    write-up, I went back and corrected it so it wouldn't look 20    so ! ad, and I am going to distribute it.
21                DR. REMICK:    They are not errors.          They are just 22    ways of possibly improving.

11            Whether we will need or desire to issue a formal 12 report on the OA portion, I personally look to Forrest (Oy          13 Remick to offer us guidance on that, since he chairs the 14 ACRS OA Subcommittee.

19              It is sort of a paradox for me to see all the 20  statements in here, that we are going to pursue this on a 21  vigorous basis, and so forth.

2                I am afraid we are not going to be able to answer 3  -all the questions you had to ask.                You have a multitude of 4    things that cover a very wide span.                We are prepared to talk 5    about the smeltered alloy rule and the draft environmental 6    statement in detail.
7                If you do get into the follow-on ef fort, the 8    development of standards for recycling contaminated scrap 9    and the coordinated effort with EPA,-we do have Mr. Donald 10    Harmon in the audience, who is participating in that 11    effort, and he may be able to answer some of your 12    questions.
( )'            13                DR. MARK:    A question of mine, when you talk of 14    smeltered alloys, are we to think almost entirely of steel 15    or are there other materials that come to mind?
16                MR. HOPKINS:    In the particular effort we are 17    involved in, it is the result of an upgrading of the 18    Department of Energy's uranium enrichment facilities.                  It 19    includes the scrap metal which was produced as a result of 20 -
that effort.      It includes not only steel but nickel, copper, 21    aluminum as well.
22                So those are the specific things that are 23    discussed in the draf t environmental statement.
24                DR. MARK:    Now, you mentioned four important

2                MR. HOPKINS:        In this particular rulemaking, 3    yes.
4                DR. MARK:      But in the real world nituation?
t 5                MR. HOPKINS:        Let me refer that to Mr. Baker.
6                MR. BAKER:      I would say primarily that would be 7    the major metals.      Certainly you are going to have some 8    minor constituents in nuclear reactors, and so on, that you 9    could recycle.      Gold, for instance, you might want to 10    recycle.
11                DR. MOE L'LE R:    There have been examples of burns 12    on people's fingers from wearing recycled gold rings.                            ,
()          13                MR. HCPKINS:        The recycled nickel is the main 14    component of the smeltered alloys we have considered as far 15    as the value is concerned.            Nickel overwhelms all the rest 16    of it, and if my understanding is correct from other more 17    generic studies that I have seen, steel would be the main 18    component coming out of the nuclear reactor decommissioning 19    effort.
20                DR. MARK:      Thank you.
21                MR. EBERSOLE:          Let me ask this.            At one time I am 22    sure it was extremely important to obliterate the physical 23    characteristics of the components.
24                Isn't that archaic now?                  Do you do that any more?

4            MR. BAKER:    The nickel was smeltered for that 5  reason, only the nickel.      The steel and copper -- the copper 6  was windings, motor windings, and the steel is just steel, 7  and this was not sm sitered.
8              MR. EBEFSOLE:      I just thought I would mention the 9  problem in smelting of achieving a homogeneous mix,.whether 10          or not that is any longer important to smelt simply.
11                    MR. BAKER:    I couldn't answer that at this time.
12                    MR. EBERSOLE:      Sometime it might be important.
()                          13                    MR. HOPKINS:      I think tno smelting in this case 14        was not dono strictly for classification purpoues.            It was-15        done to extract some of the impurities, radioactivo 16        impurities from the materials.
17                    MR. BAKER:    There were two reasons.      It was a 18        good way to got rid of the classification as well.
19                    DR. SHEWMON:      A very handy way to consolidato 20          things and make sure you know what the average content is.
21                    HR. BAKER:    They smelted up the nickel there and 22        put it on a slab in ingots?

l              18 concepts that we have always wanted to use, is to put this l
19  in something that was, as you said, not dangerous to l
20 anybody, like the general public.            You could make bomb l              21 casings out of it or something like that.            Military i

3              DR. MOELLER:      Well, one other question though on            T 4 this:    your environmental statement says that so many tons 5      c.his steel is produced from the Nevada test alte -- I 6 believe it said.
7              Where did they get the technetium, and so forth?
8              DR. SHEWMON:      They also say they aren't sure of 9 the contamination level out in Nevada.
10              MR. BAKER:      We put that in there just to show 11 that this is the amount of metal that we have in the DOE 12 inventory.
()          13              DR. SHEWMON:        Nevada is a large source.            Is this 14 from the underground testing?
15              MR. BAKER:      I am sure from the testing, yes.
16              DR. SHEWMON:        They said that they did not know 17  the waste concentrations or the contamination concentrations 18 were not well characterized there.
19              So it is not clear to me at least that technetium 20  is part of the problem.
21                MR. BAKER:      We weren't going to smelt that scrap 22  up.

4                    Can you tell me how stable the oxide is and what 5        the vapor pressure is?
6                    MR. BAKER:            I am sorry, that is a little out of 7        my field.
8'                    DR. SHEWMON:            Marty?
9                    DR. STEINDLER:              I think the vapor pressure is 10        pretty high at the melting point of steel.                      The stability --
11        well, there are several oxides, but if you get the plus-4 12        oxide I believe it is sufficiently stable.
()                      13                    But that is guessing.
14                    DR. SHEWMON:            You are saying that you don't think 15        it will stay in the metal whether it ends up in the slag or 16        it is deposited in the flue gases?                      You don't know?

5                DR. MOELLER:      I agree.          I think we can learn the 6    details of this particular problem, but we do want to keep l                7    in mind the broader range aspects.              That is what we want to 8    address.
9                DR. STEINDLER:        The point you raised concerninq l              10    cleanup prior to smelting and cleanup during or after 11    smelting is somewhat dependent on the type of 12    contamination.      Technetium is one thing.          Uranium is j              13    another. Pission products, mixed or otherwise, are a 14    third.
15                Some of them are intractable, in the sense that 16    they don't remain as oxides.          They can reduce and become l              17    alloys at that point, and 11fe gots somewhat more difficult, I
18    especially since you are dealing with material that has 19    essentially no value.      It is a waste product.
20                DR. MOELLER:      Excuse me.          It could well be that i              21    our conclusion -- and I am jumping ahead -- but it could bo l
l              22    that our conclusion this morning will be that we need to 23    schedule a meeting, have EPA come over and tell us what f
l              24    guidance they are developing and what the basis for that 1        25    guidance is.

2    Jesse mentioned the cobalt-60 Mexican incident, but that is 3    a whole other kettle of fish.      It is totally different. The 4    source of the proll m is totally different.        It is a 5    five-year halflife versus 210,000 years, or whatever 6    technetium is.
7              So it is to me totally a different problem.
8              DR. STEINDLER:      Let me suggest that in the modest 9    lifetime of an industrial chunk of material it may not be 10    all that different, especially if the source to fairly 11    high. Five years is an uncomfortably long halflife for 12    something that is trivial in relation to, say, technetium.

6              DR. MOELLER:    Good.
7              MR. HOPKINS:    To begin with, the events which 8  precipitated our consideratio.n of the smelted alloy recycle 9  request was the fact that the Atomic Energy Commission in 10  its enrichment plant operations went through an upgrading of 11  those operations and replaced a large number of the 12  components metals.
(o,)                      13              The metals which were replaced then became scrap 14  metals, but were found to be contaminated, not only with 15  uranium but with technetium-99, a product which originates 16  from a byproduct of the reactor process which was introduced 17  into the enrichment process.
18              In recycling of uranium back through the 19  enrichmust process, DOE recognized that the very large 20  quantities of contaminated scrap, to do something with, it 21  should consider within its own confines what it should do 22  with that, and it recognized that it had several options.
23              Some could be used internally.          It could be 24  recycled to a particular place perhaps for the manufacture

(  j DAVbur          1              What they chose to do was to try to decontaminate 2  the scrap metal to the extent that they could, to then smelt 3  it, to extract whatever it could in the way of contamination 4    that was left, assure that it was below'certain limits, and
.                        5  to re.:ycle it into the general economy.
6                This eventually presented a problem, as you may 7    know, in that when you recycle it into the general economy 8  it can go anywhere, into personal items or consumer items..
9              -In February 1974, the AEC operations asked the
_10    AEC regulatory side to establish some de minimis 11    quantities. They wanted these de minimis quantities of 12    course-to include quantities to which they could
()                - 13 , decontaminate the scrap so they would be able to use the de 14    minimis quantities to be able to put the scrap out into the 15    general commercial process.
16                In the following month, March 1974, there was a 17    favorable response from AEC regulatory.
1 18                The problem at the time, there was already an
{                      19    exemption in the regulations for contaminated uranium, 20    uranium whether it is contau.inated or part of ores perhaps.

3                    So it didn't qualify under the existing exemption 4-      which was for natural or depleted uranium only, and we had 5      no authority at the time to' offer an exemption for enriched              ;

.                  '7                    But in a very short period of time Congress was 8        expected to act to change the Atomic Energy Act to allow us 9      to have exemptions.for special nuclear material.
So the AEC 10        favorable response included reference to that Congressional
!                11        action and anticipated that it would be favorable and that 12        we would be able to go ahead with the exemption.
l( )          13                      Anticipating that AEC regulatory would go ahead 14        with the exemption, the operational side of AEC promised to 15        produce an environmental impact assessment which covered 16        what the benefits and derogatory parts of recycling of this 17        contaminated scrap would be, and they contracted -- they, 18        AEC operations -- contracted with ORNL to produce this 19        environmental impact assessment.
20                      It was produced and provided to us in September 21        1976, a little over two years later after the favorable 22        response from regulatory.

23                  In July 1979, there was a follow-up request by 24  the Department of Energy in which they identified that they I

(            .1 2  like to recycle into commercial channels and they had use 3  for that money.
4              In September 1979, we had an internal memo 51 requesting concurrence in the proposed rule.            At the same 6  time we distributed the proposed rule in the draft 7  environmental statement to all the agreement states.
8              I.saw no record of a response from the agreement 9  states, which either means that none responded or that they 10  all responded and had clear responses, 11              In August 1980, SECY 80.384 was sent to the 12  Commission, recommending that the Commission approve the j I          13  proposed rule for exempting these materials, which were in 14  fact the DOE smelted alloys but they weren't identified as 15  such.
16              Management had made a decision that we should not 17  be in a position to publish an exemption which benefitted 18  only one group.        So the exemption was written so that other 19  people who had similar materials would find that they were 20  also exempted, although we knew of no similar materials, 21  certainly not in large quantities.
22              The Commission approved the paper 3 to 1, with 23  Commissioner Bradford dissenting.

s                                                17                                                          One is because they claimed that it had a 18                    classified configuration and they needed to get rid of that 19                    classified configuration.
20                                                          Tpe second is that it is by far the most valuable i                                              .21                      of the metals which they had, and they were looking forward i                                              22                      to being able to reclaim that value.

8                            The only other thing which has been done with 9        these metals to date is that the steel has been sized.                                                                                  From 10          the very large pieces that were initially available they 11          have cut it into smaller pieces so that it is handle-able.

8                                                MR. HOPKINS:                              A proposed rule was published in 9              '80.
10                                                What the decision was at that time was to move 11              ahead and see if the public comments, including'those from I
12              EPA, could be taken care of.                                                                In fact, the efforts for a
()            13              couple of years then were to presume that we would go ahead-14              with the rule, to finalize it and to change the draft 15              environmental statement to include information in response 16              to the public comments received.
17                                                That-direction was changed probably two. years 18              ago.              When we had in hand the draft final environmental i
19              statement, we saw what had been done to counter the public 20              comments.                        We saw what could be done to rule to counter the 21              public comments, and we decided that in view of everything i
22              that was happening and also in view of the fact that there 23              were several other requests for similar exemptions, that 24              what was really needed was not an ad hoc approach to each of

HOPKINS:      Much of what you say is true, but 2 there was no existing Part 70 list because we were not 3 allowed to have exemptions of special nuclear material up 4 until this time in 1974, when the Atomic Energy Act was 5 changed.
6            So there was no existing list to add this to.
7 The existing exemption was of natural and depleted uranium.
8 Thnt would have been in Part 40.              We couldn't put an 9 exemption in for enriched uranium in Part 40, you had to go 10 into Part 70.
11            The technetium exemption would have gone into 12 Part 30, and there is an existing list of exempt material h            13 there.
14            So, for the enriched uranium, this would have 15 been the first.
16            DR. FOSTER:      Right now, the regulation is 10 CPR 17 Part 70. It does have an exempt list.

19              MR. BAKER:      Probably, unofficially, I suppose it            i I

()DAV/bc 2              DR. PARRY:      Do you mean the balls in the bran 3 mill for processing ore?
4              MR. BAKER:      That's one of the ideas.
5              DR. SHEWMON:      Those crude things are reasonably 6 sophisticated alloys.if they last very long, and they don't 7 have a lot of nickel in them, but go ahead.              You know.
8              MR. BAKER:      That was one of the ideas.
9              DR. SHEWMON:      For useful products, DOE is not in 10 the business of manufacturing them, so I don't see that --
11              DR. MOELLER:      --as a viable alternative.
12              MR. BAKER:      That's why we didn't push it at the (J-          13 moment. This wasn't one of the alternatives that was 14 pushed.
15              DR. SHEWMON:      But it's not to'a controlled 16 supplier. They could not say:            Give it to Allegheny-Ludlum 17 and say use this in the next batch.
18              MR. BAKEk:      No. It would have to be within the

3 make whatever needs only by having that commercial smelter 4 be a licensee.
5              If you could license that person to take the 6 DOE's waste _ scrap and smelt it with whatever controls are 7 necessary to go along with the process, and you could give 8 it back to DOE in whatever shape it wants, that involves 9 only one licensed operation and does not involve any of the 10 recycling into the commercial sector.
11              DR. MOELLER:      I guess that raises the question i                12 that Jack-Parry has mentioned to some degree.          Let's say you j  )        13 license this commercial group and they made whatever they i
i 14 made -- stainless steel, or something, out of it -- then 15 what about the next batch that goes into those same vats, et i        ~

7                would both qualify for the strategic reserves.                                            So there are 8                a number of actions that DOE could take far short of 9                exempting the material for use by the general public.
10                                                One thing that I failed to mention in my earlier 11                  presentation was that there were separate comments received.
12                on the rule.                        The rule, we received 3,700 comments on; there
()-                          13                  were a separate number of comments received on the-draft 14                  environment statement.                            These numbered only 24.
15                                                Among them were comments from the Environmental 16                  Protection Agency.                            Also, a lot of detailed comments from 17                  the Department of Energy and a few other detailed comments 18                which were helpful.
j                                    19                                                There were also a number of other kinds of 20                  comments, which were just expressions of people's feelings 21                  about the rule, actually.
22                                                DR. MARK:        You said there were some other 23                  alternatives which you hadn't thought of, like recycle 24                within the agencies, including the Department of Defense, in

9              Why were none of the internal agency solutions 10  seized on as being the obvious thing to do?
11              MR. HOPKINS:      It was not recognized at the time 12  that the solution that was proposed, that of recycling-this
()          '13 material in general commerce, was not feasible.
14              DR. MARK:      It was feasible by just getting a 15  license. It isn't feasible from the point of view of 16  deciding that you know what they've done.
17              MR. HOPKINS:      That's more obvious now, I guess, 18  than it was back then.
19              DR. MARK:      Why not go back and say all submarines                !
20 may use this steel.        And if they need some more, they can 21 get some fresh stuff.

,"                2 of the main content of our draft environment statement.
3            We have a summary which included a discussion of 4 the alloys which we were going to discuss, and which were i
5 stated to us as being part of the materials which we would 6 release into the general commerce.
4 7            We discussed a description of the scrap and its 8 possible decontamination methods and the smelting and what 9 the reductions would be in smelting of the uranium and 10 technetium.
11            Our economists discussed the market for the i
12 smelted alloy and estimated what these markets would be in
()            13 the-future. They foresee it might be quite different now 14 than what they wore extrapolated to be, i
15            We covered the predicted impacts of the smeltered i                16 alloys. These impacts were during the manufacture and so 17 on. We discussed the radiological impacts and the societal.
18 impacts.
j,                19            On our radiological impacts we included about 20 anything that you could make out of these materials and,' as r-21 I said before, we included very personal items at the time.

(}DAV/bc 2              DR. CARTER:      This was always done on the basis 3 that the material was undiluted; is that correct?

7              Now, quite a few years have passed and we think a 8 little differently now about this.              -Some of it, I think, is 9 a little hindsight because we now have this ALARA principle 10 that we're sort of looking at.            And, hopefully, we sort of 11 feel that's the way we should look at it.

12              MR. BAKER:          We had that reference.
13              DR. MOELLER:          While we are in Chapter 2, on page
      .l( )
14  2-3, TaLle 2.3, you give-the quantities of copper, steel, et 15  cetera, that you anticipate in scrap metals for BWRs and 16  PWRs and how much technetium is going to be in that metal.
17  I ask, because my presumption is, none.                    So I find the 18  comparison, or I find the table of little use.
19              MR. BAKER:          We took it out in the final, because 20  it was just put in there for comparison or something                          How 21  much metals we think would come out of the commercial power 22  reactor program.        We did not state here what radionuclides 23  these metals would be contaminated with.

8                  DR. REMICK:      What would it be in a case like 9    this?
10                  MR. BAKER:      You could go to the extreme.            ALARA, 11    you try to get a balance here, and you don't go to one 12    extreme or the other.        The balance point is more or less

19                  In Table 1.1, on page 1-4, most of those 20    exposures that have been calculated, you know, are fairly 21    innocuous, but there are two that aren't.              One is the skin 22    dose over a 50-year period.            The other one, though, is a l

  }DAVbw 2                MR. BAKER:      I realize that.
3                DR. CARTER:      Certainly, I would think that bone 4    in this case is a critical organ, at least my bones would 5    be.
6                So that sort of thing, it would appear to me, 7    certainly, there is no saving grace about having a bold 8    implant made with radioactive material versus no radioactive 9    material.
10                Have you done anything?              Are those calculations 11    on that sort?      Have they been looked at again?            Checked, or 12    whatever?
I)          13                MR. BAKER:      Actually, then we pulled back, as I 14    said, and it was more or less academic, because we weren't 15    going -- this license would not be for releasing this into 16    this type of marketplace.
17                DR. CARTER:      Because obviously, in this case, if I
18    you're concerned with a change in the quality factor, you're 19    obviously over the criteria.            So historically, this could 20    change considerably.      I dare say these numbers would look 21    quite different, if these calculations were made today.                The 22    numbers would be considerably higher.

6300 05~04                                                                      59 1  thought, look on page 4-22.            At the top of the page, Table
(}DAVbw 2  4.14, it's a table of how it affects risk factors, and it 3  says " Type of Risk:      Cancer from total body exposure."
4              Okay.      Even if you took that as fatal cancers 5  from total body exposure versus just simply morbidity and 6 ' mortality, you would get a higher number.              You have here, it 7  is 50 x 10 to the -6 per rem.            Well, it is actually 2'x 10 8  to the -4, 200 x 10 to the -6, and if the Japanese -- and of 9  course, you didn't know about this at that time, but if the 10  recalculations of the Japanese survivors doubled the risk, 11  you are talking 400, but even with 200, you are of f by a 12  factor of 4 from what is commonly accepted today.                And this 13 (f              report is published in 1980, and ICRP was certainly out.                26 14  was published in 1977.        So I did not understand that number 15  at all.
16              MR. BAKER:      Which number?
17              DR. MOELLER:      The 50.        If I a reading it right, 18  it is 50 x 10 to the -6, and it should be at least 200 x 10 19  to the -6.

y          13              DR.

21              MR. BAKER:      Small scale tests.
22              DR. STEINDLER:        Not only are they small scale, 23 but they are atypical in other ways.            For example,  that 24 test on the nickel barium material was done without a flux.

3                DR. CARTER:        I wonder if Dave could comment on 4  the fact that the exposures are related to the degree of 5  enrichment of the uranium.-            The statement is made in 6' ~ Appendix A-2,    for example, that if you release a larger
: 7. quantity of material, for example, than that above, say, 1.5 8  percent enrichment in the doses that are calculated in this 9  Draft Statement, maybe an order of magnitude more.                        That was 10  certainly pretty close to the old limit.
11                DR. MOELLER:        Say that again, Mel.                                  3 12                DR. CARTER:        Apparently, the degree of
()          13'  contamination depends upon the degree of enrichment.                        Since        ,
14  we_do this a little differently at each of the enrichment 15  plants, presumably it makes a difference where this material 16  comes from.      The source can be related to the level of 17  contamination. -This is made, by the way, on page A-2, at-18  the end of the first paragraph.                Therefore, if a-large 19  quanity of metal contaminated with uranim or greater or 20  1.5 percent enrichment is released, dose to the public could 21  be up to an order of magnitude higher than those reported in 22  Chapter 4.

L                  14                    And again, with in that, we would look at what
: j.                15  Mel just covered, the enrichment of the uranium.                        If it can
: f.                16  be an order of magnitude higher, that is a very serious
!                  17  aspect.

l                  21                    That is the first major thing, to see the updated I
22  Environmental Statement.
23                    Secondly, we, as a subcommittee, need to talk to 4

3              I would like to preface that by pointing out that 4  what you are not going to see is an algorithm for rating one 5  FIN relative to another.          In other words, do we keep this 6  FIN or drop that FIN?
7              Our present budget level in FY '86 and FY '87 for 8  high level waste research is S3 million.                It doesn't really 9  permit us the luxury of having any FINS which are relatively 10  more important than any others.                They are all the same 11  priority as far as we can determine.
12              In fact, we just went through an exercise, part
()          13  of an exercise, that the whole Office of Research is doing, 14  trying to prioritize FINS, and the difference between the 15  FINS, between the highest and the lowest, was attributable 16  to noise.
17              DR. MOELLER:        You say you are so short of money 18  that you can only do top priority items?
19              MR. COSTANZI:        Absolutely.
20              DR. MOELLER:        There is nothing low level on 21  this?
22              MR. COSTANZI:        Nothing, no.
23              So we are definitely bare bones.                There is no 24  question about it.

()          13 areas that we have been working in.
14              A disposal system for high level waste is 15 basically very simple.        It is working, and there are no 16 moving parts but it does have certain well-defined areas 17 with the characteristics we have addressed.
18              First is the part of the engineered structure and 19 the waste form.      Spent fuel will have silicon glass enclosed 20 in some kind of metallic overpack and backfilled with 21 materials. After that you go into the natural host rock, 22 which will be disturbed and thermally influenced for a 23 fairly long period of time because that in a natural process 24 that occurs there.        But they are different than are normally

()DAVbur 2  is a significant thermal influence, you will be in an area 3 .w here perhaps the hydrology is still affected by changes in 4  the rock or other processes but other things are not 5  affected.
6              The temperature is not a primary problem.          The 7  process is there.        Absorption and groundwater flow through 8  the matrix and the fractures is going to be similar to what 9  it would be in any other system.
10              So our program is divided up into addressing 11  issues in different areas.
12              Now, the first slido in the package talks-about
()          13  our objectivos.
14              The program started out essentially addressing 15  something which is new, and that is geologic disposal of 16  toxic wastes.      We had something called the geologic 17  repository, and we nooded to know what makes it work or does 18  not work.
19              Beyond that, could licensing responsibility -- we 20  had no way to demonstrato this, and that is really the crux-21  of the matter, is how we make this thing called a high level 22  wasto depository, how do we make it work, to isolate the 23  wasto for the period of timo that is required by 24  regulations?

3              We all know that groundwater is transported, and 4 we all know that it is designed to meet some short term j                5 objectives.      The waste package, how the waste degrades, how 1
6 the package degrades, how it interacts with the backfill
,                7 determines the integral form and species that the waste a comes out.
9              That is what we have to be worried about, not

5            DR. LOCKE:        It's done that way and it's done in 6 the prelicensing meetings.            It's an extremely active 7 program. We're trying to be aware of what's going on.
8            MR. COSTANZI:          It's also done continuously.        It's 9 a continuous process.          It's not like a one-shot deal.          It's
.,                  10 an ongoing process, 11            DR. LOCKE:        Then, outside of this systematic 12 meeting in getting together, we have the formal process of
()          13 project review.        After the process of identifying something 14 at these meetings that needs to be done and has to be 15 addressed, then our staff will generate a statement of 16 work.
17            They generate that statement of work not in the 18 dark, but in coordination with the Waste Management staff 19 downstairs. They go through several iterations down there 20 and then they send it down formally for coordination in 21 review to the Licensing Branch.
22            They farm it out to Waste Management and they 23 give us formal comments back.              We then incorporate this 24 statement of work.          After that, it goes to_the Waste
()          25 Management Review Group, which is a DEO initiated review ACE-FEDERAL REPORTERS, INC.

2              I don't believe there's an organization like it 3  for.any of the other research offices.            But the whole 4  process forces us into a mode of addressing ~only those 5  things the Licensing. Office and the Research Office can 6  agree are issues that have to be addressed.
7              Of. course, at the end, there is the ACRS 8  programmatic review.      We come here periodically to describe 9  what's going on.
10              DR. STEINDLER:        Who finally signs off on a 11  particular task to be tackled?            Is that the Division of
                -12  Waste Management, or is that you folks?
j( )          13              DR. LOCKE:      You mean the SOW itself?
14              DR.-STEINDLER:        Before it gets to be implemented 15 or funded?
16              MR. COSTANZI:        The contracting document is 17  actually signed by the Division director.            Prior to that 18  there are two other endorsements, one of which is for the 19  Division of Waste Management, saying, Yes, we support this 20  project. That is handled by the Chief of the Projects 21  Branch. John Linehan is now acting in that capacity -- even 22  before Carl gets to put his name on that paper.
23              Then it has to go to the Waste Management Review 24 Group in which representatives of other divisions within the i()        f25  Office of Material Safety and Safeguards, or Contracts.

4              MR. COSTANZI:        That is absolute correct.        The 5 Waste Management Review Group is John Davis' group, not Bob 6 Browning's.      I want to make that clear.      It is outside the 7 division. It is not within the Division of waste 8 Management.      It is a part of the Office of Nuclear 9 Materials.
10              DR. STEINDLER:        Let me ask the question 11 differently.      If Bob Browning or his folks do not agree that 12 a particular project that you guys have carried through the 7
13 paperwork on is worth doing, does he have essentially a veto 14 over the implementation of that program?
15              MR. COSTANZI:        Not absolutely. There is an 16 agreement, although I do not believe it is a written 17 agreement, but an understanding between both the Division of 18 Waste Management and the Program of Earth Sciences, as well, 19 between the Office of Research and the Office of Nuclear 20 Material and Safeguards, that, indeed, there may, indeed, be 21 reasons for doing some research, even though the user office 22 -- in this case, the Division of Waste Management -- may not 23 feel that it is appropriate or needed and may not support.

                '4  enough about it, Mr Minogue would endorse carryimg on with 5  the research.
6              DR. LOCKE:      Waste. Management Research,.in 7  particular, is not necessarily presented with something 13  which everybody always agrees on.                There are times when the 9  Office of the Division of Waste Management will make a 10  -comment on it in the SOW and say it is not appropriate at L              11-  this time. It is not appropriate to this contract.                  It is 4-12  work that shouldn't be done for any number of reasons, and
()          13  it will go to the Waste Management Review Group and say 14  these are the comments of the Waste Management Review 15  Group. These are the changes that should be made.                    These 16  are the changes that should not be made, for the following 17  reasons.
18                So it is an interactive process that we do not 19  take lightly.      We give them a thorough treatment and we 20  assess them.

()DAVbw' 2 Paul Shewmon raised questions on some of the research here a 3 year or two ago, and we delved into it in depth.
4            Go ahead.
5            DR. LOCKE:      I think that takes us to the next 6 slide, which is primarily a time line and another way of 7 looking at the background information that I gave you 8 earlier. It goes 'oack perhaps ten years, when we first 9 began doing the research on high level waste in a 10  significant way.      Essentially, it shows the first phase of 11  research is that one in which we are trying to identify.the 12  issues and processes which we need to study, and there is a
()            13  rather discrete line there, which is obviously very fuzzy.
14  We may still be identifying issues even at the time of                    .
15  licensing, but we are shifting the program now to one which 16  is much more directly aimed at establishing the competence 17  of the demonstration of assurance.                                        -
18              Then, of course, after an extensive period, we.
19  have to address the further issues.              Those are issues' raised 20  on occasion, even now, that focus the same characterization 12 1 and licensing and operation.
22              Yes?
23              DR. SHEWMON:      I was at the Materials meeting in          .
t 24  Columbus a few months ago, and one of the uncertainties, and f          25  thus, contentions there, was the degree to which there will ACE FEDERAL REPORTERS, INC.

4            Is there any hope that the site characterization 5 can be in enough detail to find out where these things are 6 or what they would do with it, if they did bump into them?
7            MR. COSTANZI:            I would think that, indeed, there 8 is. The DOE has to submit to NRC, for its review, a site 9 characterization plan.      Once the sites for characterization 10 are chosen, one of the things that we will do at the time 11 that those are received by the Division of Waste Management 12 is to essentially give all the things that we know, in terms
()          13 of relative considerations, the relative importance of the-14 processes and the characterization techniques, which may be 15 appropriate to particular media sites that are going to be 16 characterized by DOE.
17            That we hope, combined with all the other 18 !nformation which both we and the Division of Waste 19 Management have gathered to this point, will allow a review 20 c f what DOE plans to do and an assessment.
21            DR. SHEWMON:        This is what they plan to do duEing 22 the characterization?
23            MR. COSTANZI:            During the characterization and 24 whether or not, indeed, they are going to be doing the kinds

3-                I assume, sight unseen, that DOE will address 4  that and how they are going to investigate that under site 5  ' characterization.        Clearly, if they do not, we will have 6  some ammunition to say, hey, look DOE, you've got to address 7  this issue.      That is really our whole business, and what 8  we are going to -- that this chart is trying to illustrate 9  at this point.        Eve ry thing is ready for site 10  characterization.        That is what we have been doing.            I think 11  we know enough about uhat sorts of things DOE wants to 12  directly-address when they characterize a site, that we

7                                    DR.

10 research would be applicable to that sort of operational 11 packaging type operations, were they to be carried on at the 12 respository site.        They would not be applicable, however,.to

10            Suppose one or more of the candidate sites goes 11 through a characterization process, you end up with ,what 12 looks to be, say, empirically, a real good site, good
_ ()          13 geology, and you think, probably we wouldn't be able to find 14 a much better site in the country; however, in view of all 15 of the uncertainties which exist in modeling, particularly 16 in the far afield and the ability to measure things, you 17 have to tell DOE that, gee, you got some good stuff here, 18 but you fall very short of coming through in an ability to 19 demonstrate that you are really going to meet those 20 criteria.
21            What are you going to do about this?            Are you 22 going to say, gosh, our tools aren't good enough to show 23 compliance, and therefore, we don't have a site?

10  demonstrates that the EPA stand'ards will be met or a 11  demonstration of compliance with the performance objectives 12  in Part 60.      Our reviews center on all the event

16                The aame is over at that point.
17                RW: let me make another comment.                How do you 18    expect the public at large or the licensing process to agree 19    that you have come to cicsuPe on this issue, that you raised 20    mainly the question of confidence?                You've got three levels 21    of things here.        One is completeness, one is confidence, the 22    other is closure.
23                How do get to the competence aspect of it, if you 24    keep saying, I've got an open-ended set of issues, and I 25    can't identify how open that end is?

;              8  solve problems.
9              MR. EBERSOLE:        Doesn't it arise from the fact i
,              10  that I know all I want to know, I never need to know 11  anymore, and I never need to look again?
12              That is what brings the whole problem up.                          I will l( )        13  refuse to monitor to see whether I am right or not.
14              DR. LOCKE:      Part of the problem is you look at an 15  issue, you resolve that issue,- then you find a subissue.
16  You find there may be a perturbation of the actual final 17  calculation.
I 18-            There has to come a point when you say the 19  perturbation is small enough to do no harm.                  We are all 20  familiar with the process of ignoring higher order effects.

3                Our program is so small that we are only focusing 4  on major issues.        The process of reducing the-budget _has 5  made us stop working on basalt, which means that'we have 6  declared that as of right n6w we have sufficient information 7    on basalt to at least go through the site characterization 8    phase of the licensing process.              We are not now trying to 9    develop new information on basalt applications.
10                That doesn't mean that we know everything about 11    basalt. If.you asked us tomorrow and gave us $2 million, we 12 ~ could identify work to be done in basalt.

17                MR. COSTANZI:        I would like to point out that 18  when the Commission set up the licensing process for 19    licensing the geologic repository, almost in its entirety it
                -20  was put into law by the Congress in the Nuclear Waste Policy i                21  Act.
i                                                                                              r 22                It envisioned an extremely cautious, step-by-step i
l                23  program whereby the NRC would essentially look over DOE's l-              24    shoulder every step of the way, and it included in this the

()DAVbur 2 indeed can build a repository that will work.
3            At that time if the Commission is convinced, they 4 will authorize construction and tell 90E to go build it..
5            After DOE has built it, then DOE comes back and 6 convinces the NRC that they built what they said they were 7 going to build and it will work.
8            And if the NRC is convinced of that they will say 9 go ahead and put in the waste.            But by the way, while you 10 are putting in the waste we want you to continue to monitor 11 what is going on -- monitoring not in the sense of passively 12 looking for leaks but monitoring the environment in which
()            13 the wastes are being placed, to look at the interaction of 14 the emplaced wastes with that environment.
15            The whole physical standard.of the repository-16 right up until the time that the DOE can convince the 17 Commission that, hey, you know, we are not going to see 18 anything new.      We are finished, we have loaded, things are 19 the way we said they are going to be.            They are not 20 changing, let's close it.

6                  Do you feel that it is there after the license 7    has been granted, that they will do it with steel, that one. 3 8    should then get into the questions of, okay, what is your 9      testing and quality assurance program to show that this i
10    overpack is indeed what the modelers have assumed tit is?,
11                  MR. COSTANZI:          Are you asking when we should ask i
12      that question?                                                                            '
()            13                  DR. Si1EWMON:      I am asking if it should be asked i                14    sort of in this quality assurance stage, which, as I 1

18                  MR. COSTANZI:          No. As a matter of fact, part of 19    the site characterization plan specifically requests, as far 20    as DOE, to tell us what the waste package design 21    requirements are, tailored for the particular sites.
22                  We acknowledge that,;the specific waste package                                .

v[] DAVbur 2                My question is, one, these are not items of 3  commerce, there are no specifications on how you purchase or 4  buy these. You'can't say we are going to go buy a Ford like 5  Ford ~has been selling for that many years.
6                So the question is, okay, if it is going to be 7  made of steel, indeed is it a sound casting?
MR. COSTANZI:
8                                    We are looking at that question 9  now.
10                DR. SHEWMON:      You are having trouble.            Part of it 11  is they say, well, we are not going to build it out of 12  steel, maybe we won't.
()          13                So my question is:          do you feel that the 14  specifications on this should be fixed now, or should they 15  be fixed after you have gotten these things reasonably 16  well-decided, what you are going to build under to try and
,                17  find?
18                MR. COSTANZI:        The DOE is required to give us at 19  least some information on specifications with the site 20  characterization.        That is one of the things specifically 21  called out in the regulation.
22                We expect that at the time when they come in with 23  the construction authorization application, which is the 4

10              twofold.            One, it cuts down on exposure, so you can ignore 11            radio!ysis.                  The other is you use this as a sacrificial i;                                      12            barrier, plus it keeps it from crushing.                                  That is the

3  seems like you have decided how much you needed to know from                  ,
4  licensing.                                                                      ,
5              But one way, of course, the NRC decides what do 6  we need to know in the licenses is to restrict the budget.
7              The inference I make is that if you get a lot of P
8  money you can't decide.        If the money is limited, .then we 9  will decide.-
10              DR. LOCKE:      The statement I made was that we have 11  sufficient information to permit the site characterization 12' plan, which means that we feel we understand the~ issues.                  We f^)
v 13  have identified the issues and processes important in a 14  basalt repository sufficiently to be able to tell DOE what 15  they have to collect information on.
16              MR. COSTANZI:        The decision to essentially, we 17  think, prematurely end basalt work before we had finished it 18  was a direct result of Gramm-Rudman.              Our budget was simply 19  cut. It was cut arbitrarily.            That is just the way 20  Gramm-Rudman works.
21              The decision to cut there as opposed to other 22  programs in high level waste research was, well, we had been i
23  looking at that medium longer than any of the others.                    There 24  had been more interaction between the Division of Waste

6                After that took place, Mr. Davis wrote a letter                      ..
7  to Mr. Minogue, saying that he agreed in the budget t

10                DR. REMICK:        I understand, but that still leads 11  me to the conclusion that you were forced to a decision 1
12- based on a budget cut, a decision you'might not have made.
()          13  otherwise, and I understand.
14                MR. COSTANZI          You know, our business.is reducing              '

COSTANZI:        You know, the reason we have this 2  coordination and.this ongoing coordination with the Division 3  of waste Management, staff to staff and management to 4  management, is simply because everyone in the Office of 5  Research. recognizes that the nature of research ar.d 6  researchers is to do research.            We want to eliminate the 7  uncertainties.      We all recognize th:4t is-an unattainable 8  goal, but we need to always keep in mind the perspective of-9  what is good enough for the agency, for the regulatory 10  agency to do its job.
11-            Those interactions with the Division of' Waste 12  Management staff and management, as well as the discussions 13  of prelicensing with the Department of Energy, gives us that fs_)\
14  perspective.
15              So the judgment that we have done enough is not a 16  judgment made in isolation, not something that is arrived at 17  at a single point in time.          It is something which we 18  approach, which we review continually, and in which all 1.

10  million bucks.
11              You have obviously set some priorities.                  So 12  perhaps the selection among the-various proposals isn't q
J ,,            13 quite as difficult as you make it out.            You clearly have set 14  all the basalt focus aside.
15            Is it also true that if somebody said your budget-16 has been cut to 200 K and you write one contract that you 17 absolutely would not be able to determine what that contract 18  should be?

6 what, a fifth of what it used to be when we looked the last 7 time, which'was not too many years ago.
8            I recognize the exigencies of budgets, but.I find 9 it incredible that you say that you cannot prioritize.-
10            MR. COSTANZI:        The prioritization which I am 11 referring to is a quantification one, which gave weights to 12 various FINS against various attributes, and those
()          13 attributes are conventional attributes -- things like 14 contributions to the overall safety, reduction of 15 uncertainty, factors for whether this is a Congressionally 16 mandated activity.
17            I-can't recall, there were a number of such 18 factors, all given various weights.
19            DR. STEINDLER:        I don't need to know the 20 factors. I am just making a cooment.
21            MR. COSTANZI:        I am just saying that when we ,
22 applied these to the FINS that we have now they all came out 23 the same.

that was done in a subjective 3  way, looking at where we were.
4            1There is a numerical value that is associated 5  with the degrees and likelihood of success of the research..
6  Had that decision been made. during this prioritization 7  exercise, it would have-contributed to that, and I probably 8  would have rated those a little bit lower.
9              I can't say that the difference between the f
10  basalt work and the other work would have been 11  distinguishable.      We certainly do have some range of values 12  in this quantitative scheme, and one could say, well, here
()          13  is where we draw the line at some time here and do it that 14  way.
15              My only argument is that we made that decision to 16  eliminate the basalt work.          I gave you a consideration in 17  making that decision, but I can't really honestly say that 18  that was the best decision we could make.            I can't tell you 19  whether it was a good decision; that is to say, I don't know 20  if it was a right decision.
21              But it is a decision we had to make, and we made 22  it. So that is pretty good.

  .;    DAVbw.      1                  DR. LOCKE:'    I am going to make a couple of' 2    remarks about techniques used to make decisions betweenLA
;                    '3    and B, where A and B aren't necessarily quantifiably 4    discernable.      When you use some kind of theory like that to 5  .make any kind of a political, social or economic decision, 6  fyou are fooling yourself, if you say that it properly orders 7    them._ You are-doing well, if you can demonstrate that 8    certain things fall out in certain modes.
9                  This was found years ago in the reactor siting 10    area, when people tried to differentiate between reactor 11    sites by comparing so many things that it became foolish' to
                    -12    say that we have sites A, B, C, D and E,              in that order.
()              13    Usually, you had three sites, which had benefits and 14-  dis-benefits, and on the whole, they were equal.                    -When wo 15    came down to do the prioritization on the research problem, 16    we are doing the same thing.            We are trying to take 17    qualitative statements, put numerical values on them, add 18    them up at the end and make some kind of a rank ordering of 19    these things.      And it is' flat-out impossible, unless you can 20    get them approved, if there are certain characteristics 21    about certain research projects, which make them much more
                    .22    important than you get the projects, and there will be some 23    obvious way of discerning between them.
24                  That did not happen.            We sat in the room with the
()              25    project managers and tried, with the best of our ability ACE-FEDERAL REPORTERS, INC.

(}DAVbw 2              MR. EBERSOLE:        Is there a document that describes 3  this analysis?
4              DR. LOCKE:      There is..        I didn't have a clean' copy.

8              MR.~COSTANZI:        I suppose we can.            I am going to 9  have to check with Denny Ross about that.                  And I don't know 10  if he is ready to release that.
t 11                DR. PARRY:      I think it is interesting to note, 12  though, that DOE used precisely the same process that you
()            13    did and came out with the basalt as their lead cite.                          I find 14  it also interesting that your grouping was horizontal, that 15 '  is, by geologic type, as opposed to being a. horizontal kind
                '16    of cut, like all waste package work should be carried on or 17    all hydrologic work should be carried on.
18                DR. LOCKE:      Were you talking about a decision 19    point or prioritization?        That was taken months ago.
;                20                DR. SHEWMON:      I have a different question.
21                DR. PARRY:      It is the same process that was used, 22    though. One has now decided -- one group has decided to 23    ignore basalt.      The other is saying basalt is our best.

2  50 words or less, what is the status of it?                Will we hear 3  about it again soon?        Have you agreed to let a contract, or 4  what?
5              MR. COSTANZI:        The FFRDC is being handled by the 6  Division of Waste Management.            Joe Buxton is the fellow who 7  is really dealing with that.            I can just briefly tell you 8  how research is involved in it.              A notice of intent for the 9  FFRDC was published in the Federal Register.                  The connon 10  period on that, I believe, closed just recently, or is just 11  about to close.        An RFP will be issued, I believe.            That' is 12  the current plan.        Research will have some work in that RFP,
()            13  experimental work.
14              DR. SHEWMON:      Will you be constrained to go or 15  strongly pushed to go with that same contractor then?
16              MR. COSTANZI:        More to the point, we feel that it 17  is going to be in our literal benefit to go with the FFRDC 18  contractor, to the greatest degree we can.                One, it 19  eliminates the apparent conflict of interest problem.
20  Whether it is a real problem or an apparent one, it is still 21  one that goes away.
22              Secondly, it provides a lot more stability, in 23  terms of keeping that contractor, keeping expertino on 24  board. Now we have had contractors say, well, we worked for
()            25  you last years.        We don't want to work for DOE.            See you ACE-FEDERAL REPORTERS, INC.

Some of these Vugraphs may look a little 9  familiar, but I just thought -- I changed the tenses on a 10  few of them.                                                                i 11              (Slide.)
12              We had this Workshop on Validation of the R( )        13  Mathematical Models, and we had a subtitle, sort of a 14  caveat. We realized complete validation is pretty much an                I t
15  unattainable goal in_a lot of these long-term performance 16  predictions on high level waste, so what we were trying to 17  get out of the workshop was a way to build confidence                      i 18  through coming up with synthesis of experiments and                  "

4              (Slide.)
5              How it is conducted depends on the final review 6 of what we have already had.
7              The January 15th meeting, I went into some 8 definitions that I will just go through briefly here.
9              One is on validation.              What we are trying to get 10 on validation is assurance that the models are true, 11 adequate, at least representations of real physical 12 processes and systems that they claim to represent, and what
()          13 we met by a mathematical model is not a computer program or, 14 as some people call them, codes.
15              There's lot of gibberish about codo validation, 16 but these are models that may or may not be implemented by 17 the programs.        So I put up this definition of mathematical 18 models. It is some sort of equation.                I put down several 19 classes there of equations that subject the various 20 constraints that you need to have, in order to get solutions 21 out of the equations.        The mathematical information you need 22 to get the solutions in order to make sense of these 23 equations.
24              DR. SHEWMON:      You are not going to insist that n
( ,)        25 all of your equations had analytical solutions?

8 What is the output of these things?              Do you predict 9  concentrations?
10                DR. Rt.NDA LL :  Yes.      The main thing you want to 11  know about is concentrations, the quantities and rates of 12  radioactive material accessing the environment.                  So-
              -13  concentration, of course, is very important.                It also means O            14  other things like pressure distributions, groundwater flow 15  fields and temperature fields, as they all influence the 16  transport of the nuclides and tell a lot about the chemistry 17  of the transport medium, because they can slow down 18  nuclides, unless you design the repository cleverly.
19              DR. CARTER:      You are predicting physical 20  parameters that, if there were things there, could be 21  measured, presumably, or you'd have no problem doing it.
22              My question is, how are you validating these                      1 23  models, when I presume you have nothing to measure?                  What do ')
24  you mean by validation?

8                DR. CARTER:      But it is another plan.
9                DR. RANDALL:      We do want to build up enough 10    confidence that we are extrapolating in the right 11    direction. We did have labs tests and analogs in some 12    fields. That is the sort of thing that we try to focus on.
7 w          13                DR. CARTER:      My point is, it's not a validation, 14    in the sense of like reactor effluence, and so forth, that 15    you can actually predict what is going to happen and 16    transport movement in the environment.          You can actually 17  '
measure those things and then validate them up            .
18                DR. RANDALL:      Reactor problems are shorter-term 19    problems that we can do tracer tests that are similar to 20    radionuclide migrations and some validations like that, but 21    they don't give the time factor.
22                DR. STEINDLER:        I think the point that I think 23    Mel is getting at, which I would like to restate it, is in 24    that definition of validation, you don't show any notion

2            DR.

We are, in a sense, confidence building.
7            DR. STEINDLER:        If you had added to the 8 validation definition, a phrase at the end that says 9 something to the extent, let's see, you have assurance that 10 mathematical models are adequate representation of the 11 preocesses and systems they represent, in time, then I think 12 I would have been a little more comfortable, because I can m          13 validate the bejeebers out of something.
14            DR. RANDALL:      I could write something that says 15 space and time.
16            DR. STEINDLER:        But I can validate the bejeebers 17 out of something in a short space of time, but you need one 18 more infinitely crucial aspect.            That is the assurance that 19 is a long-term mechanism or description that is valid over a 20 long time. You don't seem to focus on that in those three 21 things you've got up there.
22            Is that my interpretation?
23            DR. RANDALL:      You're talking about initial 24 conditions. That implies that you're talking about time 25 dependence. To me that is a very important problem of time ace-FEDl!RAl. REPORTERS, INC.

22            I understand in their current thinking that there 23 are one or two embedded salt sites and one dome salt site 24 which they are looking towards as being very high in their r^s

()DAVbur 2 much of it really matters.          The criticality question. We 3 are going to do that.
4            First, I have to try to summarize the workshop
                                                                          ~
5 and extract the suggested experiments.          I am being helped in 6 that process by a couple of contractors who may have to run 7 those ideas past various specialists in my branch and our 8 contractor network and also past the licensing office.
9            Once we do that we have the basis for the second 10 workshop. How do you do a few of those critical experiments 11 and fit them into our program?
12            DR. MOELLER:      Any other questions?
()          13            Yes, Carson.
14            DR. HARK:      I have a feeling that it must be very 15 hard to decide what you need to do and what you don't need 16 to do.
17            For example, the DOE thinks it wants to use 18 silicon sand to pack its cannisters in.          It doesn't matter a 19 hoot to you.      You just have to find out whether it works the 20 way they say or not?
21            MR. COSTANZI:        That is right. We have some 22 indications that they themselves are considering that.            DOE-23 has not declared itself in all arenas, but we are following 24 what things they are looking at in anticipation that that is
()          25 what they will use.

2            DR. MOELLER:      The meeting will resume.
3            As those of you who were here at the time of our 4 lunch break realize, we did not cover two items this 5 morning. One of them was on the natural analogs, the other 6 was on the international cooperative effort on waste 7 research. We postponed the international cooperative effort 8 until a subsequent subcommittee meeting.        And I want to put 9 on the record that I personally apologize to the NRC Staff 10 for doing that, because they have been down here about 11 three times, at least, to make that presentation, and we 12 seem never to be able to work it in, but I have been told
()l            13 that we can do the natural analogs in approximately a half 14 hour, and if we can stick with that schedule, then Malcolm 15 Knapp will have time to review the low level waste 16 management program, commencing roughly at 2:00.
17            So Nick, I will turn my floor over to you.
18            MR. COSTANZI:        Well, Dr. Gordon Richard will 19 actually be talking about our natural analog program.
20            Before he does that, I just want to explain a bit 21 about what we are looking for in natural analogs.            As was u                22 mentioned this morning, one of the critical things used in 23 models to assess the performance of natural storage areas, 24 very short term observations are in extremely long times.
[            25 We hope to get some idea of the validity of the models, as ACE FEDERAL REPORTERS, INC.

(      DAVbw;  1  well as that extrapolation process itself by looking at 2  natural analogs.
3              Natural analogs are things which occur in nature      -
4  which have properties that are in some ways similar to 5  certain subsets of properties of geologic repositories.
6              What Dr. Richard will be speaking about is the 7  use of ore bodies, uranium ore bodies and' observe the 8  behaviors of radionclides from those ore bodies as analogs 9  to the long-term behavior of radioactive wastes in the 10  environment.
11              But there are other sorts of analogs which we are 12  looking at, or I should say, which we are considering t,-)s. _      13  looking at, such as hydrothermal systems which would 14- involve, not radionuclides, per se, but other types of ores 15  being represented in hydrothermal systems heat and water, 16  which are, of course, two characteristics of high level 17  waste repositories.
18              So I would like now to turn it over to 19  Dr. Richard.
>              20              (Slide.)
21              DR. RICHARD:      Here is a simple definition of a 22  natural analog similar to what Nick just said.
23              I would like to emphasize that the fundamental 24  reason for looking at natural analogs is the analysis of
()          25  understanding of processes that occur over long time ACE-FEDERAL REPORTERS, INC.

6300 13 03                                                                          155 1 periods. This is something we discussed this morning with
(}DAVbw 2 respect to model validation.            It is the kind of role of 3 natural systems, because we looked at natural systems to 4 gain our understanding of long term behavior that we can 5 compare to a model prediction, so we can better valide our 6 testimonies and have better confidence in their 7 performance and the predictions we make using those models.
8            As you can see, we have several examples here.
9 One could be for a canister.            It could be iron nails or 10 other archaeological sorts of things.                Geothermal systems.
11 Uranium deposits, such as the one in the Northern 12 Territories.
()          13            DR. STEINDLER:        May I ask a question?            We had, in 14 that slide up there, an "and/or."                Isn't the issue in the 15 case of the use of the data from natural analogs that they 16 have to be -- both the processes as well as the materials 17 have to be comparable to what the waste system looks like 18 before the data that you get out of looking at those natural 19 systems, makes any sense to you or can be used?
20            DR. RICHARD:      I don't think it is necessary that 21 materials always be identical.            It depends on exactly what 22 the objective of the experiment is.                For example, if you 23 just want to understand some hydrologic model, I don't think i                    24 one would necessarily have to go to the same kind of rock
        -( )          25 type to understand fracture pull.                Fractures in granite may ACE-FEDERAL REPORTERS, INC.

. { '}DAVbw 2  be similarities, but one could go to different materials, 3  and-they might'still have physical similar properties.
4              DR. STEINDLER:        My point is, don't you have to 5  identify that they will have similar properties?                  Isn't that 6  a necessary part of your analog use?
7              DR. RICHARD:      Yes.      This is generally why we do 8  try to go to the same material.
9              MR. COSTANZI:        The similarity has to be in the 10  properties which control or determine the process clearly.
11              DR. STEINDLER:        Yes.
12              DR. RICHARD:      We have a very brief summary of 1    )      13  some of the results of the Australian study.              One thing 14  we've done is identified that thorium colloids could be.a 15  potential mechanism for thorium migration, and by analogy,                        ,
16  possible, also for the migration for plus 4 actinides, such 17  as plutoniums.      That doesn't necessarily mean that.there is I
18  going to be large quantities of material to transport, but 19  of the quantities of material being transported, colloid 20  transport would be the dominant mechanism as appears to be 21  the case for thorium.
22              We are going to have to do further work to be 23  able to be sure how important this mechanism is, because 24  showing that there are colloids present isn't enough.                  One
-( )        25  has to show that these colloids are not in equilibrium ACE-FEDERAL REPORTERS, INC.

3            With regard to developing procedures for 4 measuring radionuclide mobility in the field, there's been 5 work done in the laboratory and in Australian that has come 6 up with ways in which one can measure retardation in situ 7 for uranium series isotopes, but because of different 8 isotopes, if they are created by the same recoil process, 9 then one can start to understand the kinetics of the process 10 and use radon or radium as a benchmark to compare the 11 absorption of the other isotopes of the uranium decay 12 series.
O q_j          13            So that is one way one can actually measure a 14 real retardation factor, and also one can look at cores, and 15 again, the cores would give information on the extent of 16 retardation.      So we've also developed laboratory procedures 17 that have looked ut the absorption process in a 18 process-oriented mode by doing selective leaching and 19 absorption, desorption experiments, where we have an 20 artificial isotope of, say, uranium or radium, and we also 21 have a natural isotope.      So we put the sample in the 22 experiment, whether it be a batch type experiment -- one can 23 do a catch type experiment and observe the removal of the 24 natural uranium and the uptake of the artificial uranium.
()          25 One can also then later on do some leaching experiments to ACE-FEDERAL REPORTERS, INC.

9                        DR. MOELLER:                                          You did these experiments in 10    Australia, because --
,                      11                        DR. RICHARD:                                          Because the sites in Australia have 12    a rock type.                    It's closer to the sorts of systems that we
()                13    are considering in this country.                                                                  Namely, it is a j
14    crystalline type of work, also because the hydrology there 15    has been stable for a very long period of time and is fairly 1
16    well-characterized as compared to the hydrology in some 17    sites one might choose in the U.S.
18                        So I think, hydrologically, one can, for example, 19      from preliminary analysis, it looks like Florida Farrell may 20    be an interesting place to study.                                                                  But the hydrology of the 21    site is a very complex.                                                  We believe that the hydrology of 22    this site and on these sites, there actually is one that we 23    are planning to validate, and a number of sites we've looked 24    at.        So we are doing model validation and trying to do one

2  happens in the case of Australia, to make the Australian ore 3  bodies, to make uranium 234 a little bit less mobile than 4  uranium 238.      The thorium at 230 is very immobile, so it is 5  basically the least mobile constitutuent.              Then you've got 6  more mobile constituents.
7              Using these profiles, one can use that profile to 8'  compare to a model prediction of movement of those 9  isotopes.
10              DR. MOELLER:      U-235, why is it not followed?
11              DR. RICHARD:      We would follow U-235, if it were 12  different from U-238, but it shouldn't behave differently 13  from U-238, and it is in very little abundance.                  One would (f
14  assume that U-235 and U-238 would behave the same way, 15  because they are both primordial rather than U-234, which is 16  created by a recoil process.
17              DR. SHEWMON:      I take it, U-234 comes from U-238, 18  with one alpha omission?

3              DR. RICHARD:      Absolutely.        There is a substantial 4 ambient recoil which can result in the uranium U-235 ending 5 up in a different lattice position.              In sandstone ore 6 bodies, such as we have in this country, what it causes is 7 the uranium to end up in the water, so U-234 is more 8 mobile.
9              In Australia, shat it does is, it causes the 10 uranium to end up lost in a clay structure and, therefore, 11 less mobile.      So, yes, there is a substantial energy of 12 recoil. I think a few hundred kev, if you want to analyze (j            13 it.
14              DR. MARK:      I have the same question.            To 15 understand this recoil, the alpha recoil, the 238 puts the 16 stuff in the clay or the water or whatever, and then it 17 moves later.
18              DR. RICHARD:      It is true that it doesn't go 19 directly from uranium 238 to uranium 234.                There is more to 20 it than that.
21              DR. SHEWMON:      The main impact would be from the 22 alpha.

()DAVbw 2 SWIFT model, which is a very complicated model that we are L                3 using in the regulatory process to predict radionuclide 4 transport. It has been effectively taken apart to look at
.                  5 'the transport component of the model.            So what this is 6 showing is that we have taken the SWIFT' code for a set case 7 and had it do a calculation in an analytical model'which, by 8 the way, doesn't have dispersion, none of the complicated 9 density kind of considerations or thermal considerations,

11                MR. COSTANZI:        In this particular case, what was 12    done was to try to understand what was observed at the oro
()          13    bodf, and they made some deductions about the physics and 14    chemistry and what was going on.                They compared what 15    predictions would be made using that simplified model with                          ,
16    running against the SWIFT program, and what they have shown, 17    indeed, for the particular kind of ore' body that'they are-18    looking at.      They feel that they can run their analytic s

10              DR. STEINDLER: . Bear with me for the far field or 11  bear with me for a thick container, for example, where 12  radiolysis really gets down to a fairly trivial issue, as
    '( )          13  you can readily demonstrate.
14              Aren't you going to encounter, for example, in a 15  case like this, as in many others, Gabon being a good 16  example, the difficulty of relating the three target 17  repositories and their expected conditions with what you are 18  going to spend a significant effort studying here?
19              DR. RICHARD:      That remains to be seen.
e 20              MR. COSTANZI:        I think this. particular deposit 21  perhaps, like all analogs, is analogous to a piece'of the 22  repository. A particular piece of the repository this is 23  analogous to is the degraded or failed waste package 24  surrounded by an intact backfill, presumably some sort of

7              There ate certainly some things about this which 8  will not be analogous; namely, the high temperatures won't 9  be there. The corrosion products from the waste package 10  won't be there, although I to understand there is a 11  considerable amount of iron there.

15              MR. COSTANZI:        In any case, we are not sure this 16  is a good analog.      We suspect that for a portion of the 17  repository this may be a good candidate.        It is by way of i
18  these kinds of things that we are looking now, looking from 19  wherever we can to find natural systems which mirror in some 20  fashion portions of the repository so that we can view that 21  and narrow down on that and go on to some other things as 22  well.

l 3                        MS. DRAGONETTE:                First, I thought I would review 4    'very quickly a little bit on what low level waste is and' i
5    what types of waste Part 61 applies to.
I 6                        I wanted to emphasize that the definition of low 7~    level waste has developed over the years based on source, 8    not based on radioactive content or hazard.                                    It has been 9    considered in law and-in practice everything, like high 10      level waste, spent fuel, mill tailings, and transuranic 11      wastes.
12                          Under the current Policy Amendment Act it is I)                    13      everything but high level wastes -- spent fuel, mill 14      tailings, and anything NRC classifies as low level wastes.
15                          Low level waste is potentially generated by as 16      many as 20,000 licensees around the country, licensed by NRC
,                        17      and the states.                    It has produced about half and half fuel 18      cycle and nonfuel cycle                          About half comes from the power 19      plants, about half from other sources -- hospitals, 20      university research.
21                          It is generated in about 76,000 cubic meters, or
,                        22      about 2.7 cubic feet a year.                          That has boon the level of 23      production since about '80.                        With the uncertainties and the 24      cost, there has been better management.                          So the levels

15              DR. STEINDLER:          What do you mean by "as a 16  landlord, the state can veto"?
17              MS.

22              And it's a provision that was in effect since the

((}~DAV/bc 2              The state and the operator will have a lease and 3 they can impose a number of arrangements through that 4 lease. So not only do you have a health and safety-5 regulation and something that may come out of NEPA, you have 6 the state as landlord.
7              Then you have the state as their compact 8 commission representative.          Low level involves states 9 wearing a number of hats.          But the landlord is one very 10 strong one, 11              DR.

24            MS. DRAGONETTE:        There's a specific requirement

( }DAV/bc 2 environmental monitoring program and surveillance program.
3 And one of the requirements before the license would be 4 transferred from the operator to the landowner is that the 5 environmental monitoring program be in good shape and ready 6 to be able to take routine samples during that time.
7            MR. EBERSOLE:        What's the rationale about the 8 hundred years?
9            MS. DRAGONETTE:        Because, well, they could 10 continue if they chose to.          One hundred years limit is how 11 long you can rely on it in your analyses and rely on it to 12 take place.
()          13            There's no prohibition on continuing land 14 ownership or continuing to maintain fences, or continuing to 15 monitor if there's still a state agency around to do it.
16            MR. EBERSOLE:        What's the potential of this stuff 17 versus the high level waste?
18            MS. DRAGONETTE:        I'll get into that a little.more 19 with the classification charts and show you how all the 20 components fit together to work with the time lines that are 21 involved in the classification scheme.
22            So if I don't answer it later, remind me.
23            DR. MARK:      What is this bit about protection of 24 individuals?      Does that just entirely consist of some wire

5            But the pathway models that dealt with that said 6 that after a hundred years, the state no longer maintains 7 the fences. And it might look like a pasture.              Then'you 8 might have a housing development on it.              And people would 9 dig basements and grow crops in the soil that they dug up 10 from their basements.
11            It's that type of intruder, not knowing the site 12 is there.

15            MS. DRAGONETTE:          That his exposures would be in 16 acceptable ranges, yes.        I'll deal with that in just a 17 little more.

7              DR. STEINDLER:        What's your time scale over which 8 those exposures have to be monitored?
9              MS. DRAGONETTE:        At this one, forever.
10              DR. STEINDLER:        So, in a sense, you're in the 11 same, general ballpark as the high level waste folks.                They 12 say 10,000 years; you say forever.                For me, that's the same
()          13 thing.
14              MS. DRAGONETTE:        With some charts that come 15 later, I think, at the end of 500 years, things with low 16 level are pretty much to level off.                You're down to a few.
17 Your initial concentrations of your long-lived materials and 18 your intruder exposures remain about constant.
19              DR. STEINDLER:        The equivalent risk that the EPA 20 set for high level waste is drastically different than what 21 you have up there.
22              MS. DRAGONETTE:        But EPA is looking at low level 23 waste separately.

(}DAV/bc 2              DR. STEINDLER:        The equivalent of one extra death 3  in a thousand years is significantly lower in terms of the 4  millirem whole body.                                                        j 5              MS. DRAGONETTE:        This is annual per individual.

9              DR.

16              It would produce in the population receiving 25 17  millirem a year, the cancer fatality rate would increase by 18  one-tenth of 1 percent.

20              DR. MOELLER:      That is a lot higher than one death 21  in a thousand years.      It depends upon the population 22  exposed. You know, there are so many things to consider.

10              The second one was protection of the inadverdent 11  intruder. One thing to notice here is that from the 12  beginning, one of the fundamental concepts of Part 61 is
()                                                                                        13  that you think through the whole disposal procons from 14  beginning to end as you make each of your decisions 15  concerning each component of the system and what you're 16  going to do at this site.
17              This objective reflects that -- the design, the 18  operation and closure of the site are to help assure that i
i                                                                                                          19  the inadvertent intruder is protected.
20              And it also includes the premise that he doesn't 21  intrude until after you lose institutional control.

5              Your Class A waste will be consolidating and 6 compacting, biodegrading.              You will have to repair, do some 7 minor maintenance to the trench cover because you will get 8 some consolidation, the real cause for more careful 9 emplacement, more careful backfill, minimizing void spaces 10 between the packages and in the packages.

11                MS. DRAGONETTE:        Supposedly the 12  developer / operator gets off the hook after the post-closure r

4              MS. DRAGONETTE:          The releases to groundwater, 5  air, things like that should meet the 25.
6              DR. FOSTER:      The goal on that is really in terms 7' of concentration of the waste package when it is introduced 8  100 years earlier, right?
9              MS. DRAGONETTE:          Yes.      Concentration is limiting, 10  but for longlived materials your initial concentrations 11  would be limited.        Shortlived materials can be, at least in 12  Class B and C, can be at about that theoretical limit that
()            13  you could shift.
14              DR. FOSTER:      So it is a concentration combined 15  with a halflife consideration?
16              MS. DRAGONETTE:          Yes.
17              (Slide.)
18              So through 300 years your R and C waste packages 19  are holding up.        Beginning at 300 years, you continue with 20  another 500 years of passive control, the deed and whatever, 21  and you are in that period for 300 to 500 years.                      So your 4
22  Class B and C wastes are starting to disintegrate, and you 23  may start losing your intruder barrier.
24              Then after 500 years the calculations assume that

5              MS. DRAGONETTE:          It is a conservative assumption 6  to deal with that intruder.            Obviously, if he can still tell 7  it is waste and backs off and finds out what went on, 8  hopefully there would still be a land record.
9              Well, I thought maybe those would help put those 10  time lines and the assumptions behind the actual tables in 11  61.55,-Table 1 and Table 2.            That was the collective set of 12  assumptions that we used to come up with those numbers.

17              I included the things NRC has jurisdiction over.
18  As I already mentioned, we might have site inventory 19  limits.
20              One thing worth noting is that we started out by 21  mentioning that low level waste was in everything but.

[m\ DAV/bc      1              DR. POSTER:      Kitty, my other question picks up on 2  the one I had before.      Since, after 500 years, all waste is 3  consolidated and unrecognizable, this scheme says to me that 4 any Class C waste, if you waited 500 years, it would be the 5  same as the Class A waste is today.
6              MS. DRAGONETTE:          That's a fair assumption.
7              DR. POSTER:    Maybe, if you waited 400 years, 8  since the Class A waste has got 100 years to decay in the 9  first place.
10              DR. STEINDLER:        Does that mean the iodine 11 concentrations for Classes A, B and C are all the same?
12              MS. DRAGONETTE:          No.      In fact, long-lived f"
( j) .
13 materials are a factor of 10 different for A and C because
          .      14  of the dilution that you would get, the Class C waste is 15  probably going to be in the bottom, and it would be mixed 16 with the five meters of cover above it or with the debris 17  from the intruder barrier.
18              So they are different.
                -19              DR. STEINDLER:        A little bit of a strange 20  scenario.
21              MS. DRAGONETTE:          Maybe I didn't characterize it 22 'very well.

5            DR. STEINDLER:        Are we shifting the risk?
6            MS. DRAGONETTE:          It's the way the intruder for.
7 groundwater and air releases, it's site inventory that 8 counts, generally.      For the intruder, these scenarios, with 9 digging into the material, building the basement or growing 10 the crops, did take into account that you would have the 11 cover material, the amount of dirt, the diluting of the 12 waste before you did something.
()            13            If it's unrecognizable here, it's mixed in with 14 all the backfill and the cover material.            That was the depth 15 and the dilution, as I understood it.            They were two of the 16 major factors.      The.re was a factor of 10 difference between 17 A and C and the transuranics and other long-lived 18 materials.
19            I can probably try to give you a better answer by 20 calculating it, the rate.

7              MS. DRAGONETTE:        They have volume left.          They're 8 in the Rocky Mountain compacts.              I can't speculate.      The 9 political pressure to close it has gone; there's been a 10 change.

      ) DAV/bc 2                  The 1980 Act did four principal things in my 3      opinion. It made clear that the states were responsible for 4      low level waste.      It established a policy favoring regional 5      compacts as opposed to individual state disposal sites.            It 6      set January 1st of this year, 1986, as the date as which a 7      sited state within a regional compact could exclude waste 8      from states outside that compact.
9                  And it set Congress in a position to ratify these 10      compacts. That last item may be one of the main reasons 11      that the 1980 legislation was not as successful as could be 12      hoped; in the event that a compact were ratified and it y          13      could exclude waste from unsited states outside the compact, 14      then the effect is that a great many congressmen would be 15      from states which would no longer have a place to put low 16      level radioactive waste.
17                  And for that reason, Congress was unable to I
18 '    ratify a compact; although a number of compacts were 19      proposed and brought to Congress for ratification, there 20      were other problems in getting the compacts together.
21                  I think to ask what compacts were in existence or 22      seeking ratification and what states were in compacts.            That 23      answer changed almost monthly.
24                  So there was a lot of activity but not a great 25      deal of progress.      And as January 1, 1986 began to appear, ACE-FEDERAL REPORTERS, INC.

7            Very quickly running through it, the amendments 8 were signed into law on January 15th of this year.          What 9 they' done is, in Section 3, they have formalized something 10 Kitty mentioned earlier -- to make it clear that states are 11 responsible for class A, B and C wastes and that the federal 12 government is responsible for greater than class C waste.
(w j            13            section 4 principally reaffirms the federal 14 nolicy that they will want mutual compacts more than 15 individual state sites.        They are interested in having a few 16 low level sites rather than a great many.
17              Section 5 is the most complext portion of the 18 amendments. It runs about half of the 30 some paces.        It 19 does quite a few things.          It sets volume caps on the amount 20 of waste which the current operating site will be required 21 to receive in a given year, and over the seven-year active 22 period of the act, it allocates the disposal capacity within 23 these volume accounts anciq RWR and PWR reactors, sited and 24 unsited states.        And, by inference, from nonreactor

6 meet these milestones are twofold.                There are surcharges 7 which the sited states may charge generators of waste from 8 unsited states.
(
9              I will talk about what those surcharges are 10 later on. The first penalty allows these surcharges to be 11 doubled and cuadrupled as time passes an'd a state fails to 12 meet the milestones.        An additional penalty is that after a r'N

17 milestones. Now there are a number of other things that 18 would figure into this.        For example, there are volume 19 caps. For example, South Carolina is only required to take, 20 I believe, about 1.2 million cubic feet of waste annually.                        -
21 Certainly, that is one of the things that will not Le 22 exceeded by the state.        So they will not be required to take 23 wastes from Illinois in excess of that, but my reading of 24 the Act is, at least I am unaware of a basis for denial of

(Q 2              DR.

9      ,
MR.<KNAPP:      That point is well-taken, and I 10  belie #vej that is an integral part of other Compact 11  legislation I have seen in other areas.              Once they get 12  going, they are not going to want to let the thing out,
( ')          13  because they are going to want to make the money from it, 14  and of course, the motivating for generators begins to be 15  marginal, because these surcharges -- immediately, there are 16  surcharges in effect, immediately, of $2 a cubic foot.                      And 17  two years af ter that they will go to 20, ar.d two years after 18  that, they will go to 40.          So there is a high motivation 19  once you have that capability.

8              That is something that I would not like to get 9 into.
10              MR. EBERSOLE:        Does it actually get back to the 11 ratepayers?
12              MR. KNAPP:      Yes, I think it gets ' ack to the
()          13 ratepayers. The complexities of it, very simply, are some 14 of the money that goes into the surcharge will go to the 15 sited state.      Some of the money that is involved in the 16 surcharges, 25 percent, in the event that there is a penalty 17 surcharge, goes into a escrow account which is administered, 18 I believe, by the Secretary of Energy, and some of that will 19 go to the state, but can be repaid to the generator, in the 20 event that they overcome a penalty, and as I say, it is 21 fairly complicated.

            .2 about each one of these jobs.            I would just note that our 3 reading of the congressional intent is that emergency access 4 is expected to be a difficult thing to get.                It is not 5 intended to be a loophole that states can use to avoid 6 meeting their obligations under the amendments.
7            DR. REMICK:      Is that emergency access to federal 8 sites?
9            MR. KNAPP:      No.      Let me suggest that when ZI get 10 to the portion that deals with emergency access, I will talk 11 to that. If I haven't answered your question, please repeat 12 it.
13            Section 7 deals with DOE responsibilities, of f)

15 They are to provide certain technical assistance to states 16 developing sites, financial assistance, depending on what 17 funds Congress gives them for that purpose and a certain 18 amount of guidance on some things like site selection and 19 alternatives to shallow land burial.              That leads into 20 Section 8 on all kinds of disposal methods, which is going 21 to be one of the larger efforts that I think NRC will be 22 accomplishing within this year.              Within the 12 months of the 23 passage of the Act, we have to identify alternatives to 24 shallow land burial and provide guidance on them.                  Within
()          25 another year after that, we have to provide the information, ACE FEDERAL REPORTERS, INC.

8                  We are to be able to review the low level 9    application within 15 months, and we are to be in a position 10    to do that next year.
11                    And the last, Section 10, deals with wastes below 12    regulatory concern.          In that area, we are to provide both 1

L) 2                    MR. KNAPP:  This figure simply highlights some of 3 the work which will be required by the states and compacts.
4 Those deltas which are marked in red identify actions which 5 the states or compacts must take over the next several 6 years, including either joining a compact or certifying the 7 intent to dispose of waste, identifying the coming up with a 8 siting plan, and then later on, in 1990, filing an 9 application.          The additional arrows are the points.where 10 penalties will be imposed.
11                    Just very briefly, of the surcharges, which are 12 in existence, now at $10 a cubic foot, if by July 1, when a
()          13 state is supposed to have ratified the compact legislation, 14 or certified their intent to develop a cite, if they have 15 not done so, then a surcharge will be doubled between now 16 and January 1, 1987.
17                    If by 1987, by January 1st, they have not met 18 this deadline, then the sited states have the right to deny 19 access at that point.
20                    So this concern about denial of access or 21 emergency access is not something -- potentially, it is 22 coming down on us in about eight months.            That simply 23 depends on what sorts of actions individual states take in 24 the very near future.

6                      Until finally, we get to the point where, again, 7        Items 5 and 6, as you see, they overlay, so that in the l                  8        event that a state has not filed an application or certified 9        that it will be able to manage its various taxes, the 10        application may be denied.
11                      One of the things you probably should note about 12        this is that some of the staff are as little concerned about
(~)~
(              13        the timetable, saying it seems to start out rather smoothly, 14        and then all of a sudden seems to get very steep.                            And we 15        have some concerns that if a state were to simply meet the 16        timetable that has been established here, that is, in 17        particular, Item 3, if all they have really accomplished by                        .
18        the beginning of 1988 is to have a siting plan developed, 19        there is potential that by 1990, they are going to have 20        trouble having an application in to uc.
21                      So one of the things are doing through state 22        programs and through outreach to the states is trying to 23        make them aware that just meeting the deadlines in the Act 24        might very well leave them in trouble later                          n in this

(~')i 2 of rationale, is a state like Rhode Island treated just like 3 Arizona, for example?
4            MR. KNAPP:      That's correct.          But Rhode Island can 5 -- I probably should have had this as a Vuoraph -- Rhode 6 Island would be a member of the compact, and again, at this 7 point, I have to be careful.            As of -- what was it, about a 8 month ago, 37 states, 39 states were members of ratified 9 compacts. I.believe, in the last few weeks, two of them 10 have announced their intent, but Rhode Island is not going 11 to have to develop their own site.              In fact, that is not 12 what the amendments contemplate.              They want regional-
  -()          13 repositories, so that Rhode Island would be part of a 14 compact, probably in the New England region.

17            MR. KNAPP:      That's right.          It should be a 18 cooperative state venture, where the states ratify compact 19 legislation, and eventually this would be ratified by 20 Congress.
21            MR. EBERSOLE:        Is there some kind of experimental 22 basis behind all of this?          Does that come to some sort of 23 equivalency in the context of the investment to accomplish 24 this?  Is there any equivalency principle in the context of

10              As I recall, and again, this is an area that is 11  outside by competence, but I believe in the high level

8              Kitty, would you like to comment on that.
9            MS. DRAGONETTE:              My observation of EPA is that 10  they tend to approach each category of wastes separately and 11  look at technology and what could be accomplished and look 12  at it very practically, and then they set the standards.
()            13              As far as.the amendments act, Congress held the 14  hearings on the volume allocations and had industry 15  representatives, but other than something like that, I think 16  Congress was considering the low level problem in isolation 17  and leaving it up to the states to trade hazardous sites or 18  radioactive sites for prisoners, for something else.                              Sort 19  of behind the whole concept of the compact to negotiate.

9              I am going to try to go very briefly over some of 10 the work that the NRC will be doing.
11              This is the work under Section 3, 12 " Responsibilities for Disposal."            This is basically the (Gj          13 above Class C facility.        What we will be doing here will be 14 supporting, we anticipate, DOE, in their development of 15 above Class C facility.        And I think the real concern here 16 is, is DOE going to try to come up with something that might 17 be comparable to the enhanced near-surface disposal, or they 18 going to come up with something more like deep geologic 19 disposal?    And if they come up with near-surface disposal, 20 we're probably going to have to pay some attention to the 21 definition of high level waste, such that we identify 22 cu t-of f , at which point everything which is more hazardous 23 or more active than a particular amount, we will go to a 24 deep geologic disposal site, and everything which is less
(  )        25 than that will be in an above Class C facility.

17              MS.

14                                MR. KNAPP:      Okay.            One of the interesting things 15            that we have learned is that there is in fact an overlap 16            between low level and high level waste, not in a regulatory 17            sense necessarily.
18                                There is high level waste in tanks or there is 19            material identified as high level waste in tanks which is of 20            a higher activity than other materials that are identified 21            as Class C wastes.                That is one of the things that is a 22            little bit surprising.

9              DR. SHEWMON:      How to write this up and look after 10 it. Who is doing this for the states?
11              MR. KNAPP:      Okay, I am not real clear.          If you 12 are asking who might be developing low level sites, that is
(
A)          13 not entirely clear yet.          The low level site in California is 14 being developed, I believe, by U.S. Ecology, or they have a 15 contract.

6              MR. EBERSOLE:        I can see why you wouldn't.
7              MR. KNAPP:      What we are really hoping is that we 8 can really do several things, and I am sort of getting into 9 alternatives here.
10              But what we would like to do is work with the 11 states. There is some confusion on alternatives.
12              We have identified, as Kitty mentioned earlier, I ')          13 about half a dozen alternatives.              The states want help on 14 alternatives.      They want guidance, but they haven't been 15 particularly specific about what they are seekinq.
16              What we hope to do is work with them.              Doing 17 that, we would like to narrow down the number of 18 alternatives to a few that are preferred.              We have a couple 19 of options at that point.          We may be able to provide some 20 guidance.
21              We would be pleased to see a couple of private 22 companies come forward with something that would be more or 23 less consistent as alternatives.

5            And so the way we will make this thing work is to 6 provide things like format and content guides to states in 7 which we would anticipate in a number of cases they will 8 more or less adopt verbatim or very close to it, and then 9 through our agreement state program we would determine that 10 they are compatible.
11            That also applies to a number of other things, 12 like standard review plans and environmental review plans.

5              DR. POSTER:      This guidance here would not be for 6 AEC licensees, but it would be for adoption by the states?
7              MS.

17              Whether the states have to do environmental 18 impact statements on the specific sites varies from state to 19 state. Many of the states do that.

22                I don't know the state-by-state tally, but that 23 decision has been made earlier that the agrooment states are 24 not affected by NEPA.        But many of them do something very

10              MR. KNAPP:      The initial 1980 act, as I recall, 11  said that they were not going to get into transportation, 12  and I don't recall in the '85 act any mention of

2              Finally, we get to wastes below regulatory 3 concern.- At this point, I would like to return this to 4 Kitty, who will speak about where we are.              This is one that 5 is of interest because we have to have our response done 6 within another few months.
7            Dr. Moeller, if it's in the interest because of 8 the press of time, if you'd like to move on to Executive 9 Session, we'll be happy to.
10            DR. MOELLER:      If we can finish up in a few 11 minutes, let's go ahead with this.              I would like 12 clarification on how this relates to EPA.              And I gather the
()          13 answer is you are doing this independently.
14            MS. DRAGONETTE:          Yes, there's nothing in the act 15 that requires us to use or wait for an EPA standard.                I was 16 just meeting them Monday on their work.              They were briefing 17 an internal committee on their regulatory concern work.
18            The way it will impact is, if, down the road, i
19 they do come out with a standard, they may have to go back 5
20 and reassess what we've done in the interim.
21            So that's how we're proceeding.              They told us to 22 do it. There's no requirement to consult EPA, so we're 23 doing it.
24            We felt we could establish policies and
, [)          25 procedures. That's more or less a regulatory guide for ACE FEDERAL REPORTERS, INC.

                                      .1          rulemaking petitions, to explain, you know, what to submit
()DAV/bc 2          and how we handle them rather than going through a generic 3          rulemaking.
4                      With either alternative, there would be 5          subsequent rulemakings on individual waste streams.                                                It's a 6          matter of what the scope of issues that you would consider 7          might be up for grabs in each one.
8                      So, with the six months deadline, it's weighted 9          as one of the heaviest weighted decision factors.                                                In fact, 10            that policy statement gets around for the second round of 11            comments. You know, so it's moving along and, hopefully, 12            will be to EDO by the middle of May.
()                                13                        One of the things we're doing in the document is 14            to make it clear that the burden is on the person 15            petitioning for the rulemaking.                    If he wants his rulemaking                            '
16            petition handled expeditiously, he's going to have to do the 17            work.
18                        So that's a key premise in there.                                              And another 19            important consideration is that what we're talking about is 20            deciding which waste streams don't necessarily have to go to i
21            a licensed low level waste site, that would be appropriate 22            to go to sanitary landfill or hazardous waste incinerator 23            and whatever that appropriate disposal method was.
24                        They specifically evaluated and they would be
()                                25            limited to those specific options.                                So that from the

()DAV/bc 0 requirements on-surveying and compliance and making sure 3 that he indeed transferred it to the right facility.
4            There would not be any regulatory control over 5 the preceding facilities.        The sanitary landfill would not 6 be licensed.      So that's how we're interpreting it.
7            The disposal itself would not have to be 8 regulated.

12            MS. DRAGONETTE:        Delay it at least, for a number
()          13 of reasons, one of which is the EPA effort.                They're looking 14 at below regulatory concern and how to address this issue 15 more generically and establish hard and fast numbers and 16 methods for approaching it.
17            We think, for one thing, it would duplicate what 18 they're doing and it would involve several years -- if I              19 ever --.you know, the whole de minimis issue.

7              MS. DRAGONETTE:        That wasn't what we were trying 8 to do. What we were tring to do was facilitate individual 9 rulemakings on waste streams.            There will still be a formal 10 rulemaking process that has to follow the administrative procedures with proposed rules, comments and final.                        i 11                                                                          i 12              Those petitions, those rulemakings would, we
()            13 think, we could do them on an expedited basis and do them 14 quickly in matters of months rather than years.                    If you 15 follow the guidance, submit the information that's in this 16 policy statement we're developing, it would not eliminate 17 the public or state involvement in each individual 18 rulemaking in response to a petition.
19            This is guidance for how to submit a petition.
20 The legal action comes in our action in response to the 21 petition.
22              Does that help?                                                -
23              DR. STEINDLER:        Not a whole lot.
24              HS. DRAGONETTE:        We're asking for comments on the 4

(~') DAV/bc  1 statement, you can submit comments.                  And, right now, it's L.)
i worded so that if we got serious significant comments, we 3 could revise it.
4              In six months, I really didn't have time to go 5 over the proposed policy statement comments in final.                        So 6 one of the things that can happen is you can comment on the 7 policy statement itself, before any petition is filed under 8 it.
9              secondly, you can participate in the rulemaking 10 for each individual petition that is filed, 11              DR. STEINDLER:          Do you mean rulemaking for each 12 individual petition?          Do you mean licensing action?
_()          13            MS. DRAGONETTE:            No. The last item on there, 14 licensee proposals will continue under 20.302.                        If there's 15 one sandblasting sand, that should still come in as an 16 individual licensing action as 20.302.
17            This policy statement is dealing with more 18 generic waste streams where a category of licensees would be 19 able to use it.          The waste oil petition that is pending is 20 an example. It's for a thousand gallons of waste oil at 21 each nuclear plant in the country.
22            So the petition fartrulemaking, the only time we
                                                        .:.          e 23 think it makes sense to go throligh- rulemaking, is when a 24 category of licensees can use it or it can be used on a (o_)        25 national basis.          And it would bey made a matter of ACE-FEDERAL REPORTERS, INC.

3                DR. REMICK:      What is that proposed individual 4    rulemaking procedure?      Are you going to publish it, receive 5    comments?    Is there an opportunity for hearing?
6                MS. DRAGONETTE:        If somebody asks for it or if 7    the Commission thought we should, the Commission can always 8    voluntarily hold information or formal hearings, or 9    whatever, on a rulemaking.          It's not very common to hold 10    hearings on rulemakings.
11                DR. STEINDLER:        Is it true, if you had a 12    rulemaking that was not contested and was put into effect,
( w)        13    say, on ordinary contaminated oil, is it clear that next 14    time somebody came to you with a thousand gallons of 15    contaminated solvent, that everybody would understand that 16    that may be a separate issue?
17                Or is this going to fall under, well, it looks a 18    lot like oil.      We've already gone through this thing, so 19    it's going to go?
20                MS. DRAGONETTE:          I'm trying to make that clear in 21    the policy statement that we would expect these petitions 22 l  that we can handle expeditiously to very clearly define the 23    ways, and the rulemaking would be specific to the way it's 24    formed.

4                        DR. MOELLER:          Back on your question, Marty, when 5      you were saying if you were someone who wanted to stop the 6      process, the high level waste standards were written without 7      EPA guidance.            They simply, you remember, talked to EPA.        In 8      fact, they had to go back and backfit the standards of the 9      regulation.
10                        DR. STEINDLER:          We all recognize that the high 11      level of limitation was certainly not so quick as to avoid, 12      you know, an interface between EPA.
()          13                        Here, the thought is that, since I haven't heard 14      any words from EPA on how fast it can move, I think the 15      thought is to act in the sense of disposing of something 16      before the EPA gets around to making up its mind.
17                        At that stage of the game, the concern I had was 18      that the public hasn' t had a chance to look at the rationale 19      in the broad sense.            But if you continue to hold a whole 20      series of rulemakings that are narrowly constructed, then I 21      think you can probably protect the interests of the public 22      reasonably well.
23                        If it gets to be a grandfather or a broad issue, 24      the guy says it's oil, it looks just like a solvent, it

5              MS. DRAGONETTE:          I agree with you.        Our whole 6 emphasis is to hone in on very specific, narrow streams, 7 specify those and the rules that would respond to those 8 petitions.
9              That still leaves one of the difficult parts of 10 it, of how to deal with multiple streams.                Now we're trying 11 to address that through keeping the exposures from any 12 individual stream very low.

  /~N 13              DR. MOELLER:      Okay.      Go ahead. But I think we'd 14 better wrap it up.-      As a final question, you have starred on 15 your third slide, you know, the policy act amendments and 16 the sections where you have made your major responsibilities 17 within the NRC.
18              What could we do?          What can the subcommittee or 19 the committee do to be of assistance?
20              MR. KNAPP:      I can think of a couple of things.
21            At some point fairly soon, I would think possibly 22 at the next meeting that you have or the one after that, 23 we're going to have feedback from the public on alternatives 24 to shallow land burial.

2 your comments on what you think of those alternatives.
3            That is the first item that comes to mind.                        There 4 is a technical capability that we are developing dealing 5 with below regulatory concern which consists of -- in fact, 6 it's pretty well-developed.          It's a computer code which 7 models the impact of waste which might be termed below 8 regulatory concern.
9            You may or may not be interested in hearing about 10 the concepts behind that model.                That's a model which has 11 been accepted and which has been working in industry and 12 might be something you could look at.
()            13            Those are the first two possibilities that come 14 to mind.
15            DR. MOELLER:      We would like to hear about that 16 because this below regulatory concern ties into the de 17 minimis dose rate, say, and, you know, in 10 CPR 20, it had.
18 the proposal that one millirem a year would not be used in 19 the calculation of collective doses.                From that point below 20 would not be used in the summing up of the collective 21 population.
22            Well, in the committee, when we responded and 23 commented on 10 CFR Part 20, or when the subcommittee did, 24 we said, in general, that probably was all right.                      But we

3            And at the time the subcommittee met, we were 4 told, oh, the British do this.            But, then, when we dug into 5 what the British do, we found that they said you could throw 6 away up to 100 personrem uncollected dose, but don't-throw 7 it away if it's more than that.

8              MR. KNAPP:      The concern we're involved in is what 9  about wastes which are chemically toxic, hazardous wastes, 10  as well as radioactive.        Generally, low level radioactive 11  wastes.
12              Therefore, they fall-under both RCRA and AEA and
    )        13  the regulations administering these acts are not entirely 14  consistent, where all of a sudden, it becomes pretty brisk 15  to try to weed your way through that.
16                So what we're looking.for, what the Congress is 17  seeking to do is to come up with a method of simplifying 18  this situation and giving appropriate responsibility to an 19  appropriate agency.
20                DR. STEINDLER:        Could we define what "NARM" is?
21                DR. MOELLER:      The question is what is NARM.        It's 22  Natural and Accelerator-Produced Radioactive Materials which 23  are not legally, generally covered.
24              MR. EBERSOLE:        You pitched de minimis then as the
()          25  ultimate biological potential through some scenario or ACE-FEDERAL REPORTERS, INC.
202-347-3700      Nationwide Coverage  800-336-6646
 
6300 20 13                                                                        259 1 process. And I want to endorse that as the only way.
()DAV/bc 2              DR. MOELLER:      I do.        And this is a very poor 3 analogy, but I find it's the best I can come up with:
4              To just say one millirem a year is okay without 5 considering for how many years that's going to last, or how 6 many people are involved, or over what space, as I say, we 7 use the analogy that someone came up with which was helpful 8 to me was that:
9              It might be all right to permit the people in 10 Washington, D. C., all the people here to have one millirem 11 a year if through that you could provide electricity to the 12 entire United States.
()          13            But it would not be permissible to give one 14 millirem a year to everybody in the United States to provide 15 electricity to the District of Columbia.
16            So there's more to it.              I think they're exactly 17 on the right track.
18            MR. EBERSOLE:        I do, too.        I've got a gnawing 19 feeling though that the low level waste in the biological 20 potential text may be more potent.
21              DR. MOELLER:      Certainly.
22            MR. EBERSOLE:        Because of the more casual 23 treatment that it gets.
24              DR. MOELLER:      I think, with that then, let me
    )        25 thank Kitty and Malcolm for what I consider to be a rather ACE FEDERAL REPORTERS, INC.

I 6300 20 14                                                                        260 1 stimulating discussion.        And what is the timetable now on
- (v'') - DAV/bc 2 these two questions you asked?              When will the public 3 comments come in, and so forth.
4              MR. KNAPP:    The public comments on alternatives 5 will be coming in in mid-May.            We will be having -- we have 6 a reasonably strong -- we will have an analysis.                  We will 7 have a meeting with a number of the states in late June.                    So 8 that sometime around that time, perhaps after the state 9 meeting, again, depending on when your next scheduled 10 meeting is, we can talk about our analysis as a result of 11 the state meeting.
12            With respect to no regulatory concern, we have tc
()            13 have something together in about three months.                  So I would 14 assume a mid-summer meeting would probably be required.
15              DR. MOELLER:      Let me thank you again.            And with 4
16 that, I will declare that today's formal subcommittee 17 meeting is recessed and we'll resume at 8:30 in the                            ,
18 mo.ning.
19              (Whereupon, at 4:25 p.m., the committee adjourned 20 to go into Executive Session.)

1. PROCELEDINGS

}DAVbw 2 DR. MOELLER: The meeting will now come to  :

3- order.

4 .This is a meeting of the ACRS Subcommittee on 5 Waste Managemeni.

6: I am Dade Moeller, Chairman of the subcommitteo..

'7 The other ACRS members in attendance are Forrest Remick, ,

8 Carson Mark,. Jesse Ebersole, and we anticipate the later ,

9 arrival of William Kerr and Paul Showmon.

10 We have with us a team of consultants,= consisting-11 of Richard Foster, Martin Steindler, W. Fauth and Melvin 12 Carter.

l() 13 The subcommittee will review various topics in 14 the high level and low level radioactive waste management 15 programs of the U.S. Nuclear Regulatory Commission, and the 16 subject of the salvaging of contaminated smelted alloys.

17 The first item this morning will be the last one 18 mentioned. The review of the standards and' policies for the  ;

19 salvaging of contaminated smelted alloys.

20 With respect to this topic, there were several 21 items that I wanted to mention. Commissioner Bernthal had 22 sent us a written request and, in fact, the Commission has

23 endorsed or has requested that the ACRS address this i

i 24 question, and he wanted us to look at this issue from the

() 25 standpoint of one, its broad range impacts or applications,

) i ACE. FEDERAL REPORTERS, INC.

(~') DAVbw 1 particularly from a generic point of view, not just in te rms

'J

~

2 of contaminated smelter alloys.

3 Number two, he wanted us to look at it in te rms 4 of its relationship to the disposal of contaminated 5 materials resulting from the decontamination and 6 decommissioning of nuclear power plants.

7 Thirdly, he wanted to know if we could address 8 its implications, not only with respect to health, but with 9 respect to industrial operations, particularly picking up 10 the EPA's call for more attention to its potential impacts 11 on the photographic industry or on the scientific 12 instrumentation industry or other industrial implications.

() 13 Fourth, he asked us to look at the alternatives

! for the use of the end product. For example, could DOE not 14 l 15 l recycle the materials within their own operations? Could l

16 ' the materials not be recycled within perhaps the commercial 17 nuclear power industry? Could the materials not be used in 18 high level waste repositories, not so much to be stored 19 there, but to be used in the structural equipment needed in 20 the respositories?

21 I also found myself asking a multitude of 22 questions, and I am sure everyone else has done the same. I 23 was asking myself what are the alternatives, in terms of the 24 source term itself. Of course, once the metal is smelted,

(~

(j) 25 the technetium is blended throughout the metal or within the ACE. FEDERAL REPORTERS, INC.

202-347-3700 Nationwide Coserage 14034 %46

(

6300 01 03 4 DAVbw metal, and there is very little hope from that point on of

(')s q

1 2 doing much in terms of decontamination. And I needed to 3 hear a little more on the effort that was put into 4 decontaminating the metal before it was smelted, because, as 5 I understand, as the technetium originally was on the 6 outside of the metal, so why wasn't it cleaned of? Of 7 course, that is a very difficult process.

8 Then you can further ask the question, looking at 9 this in terms of a specific problem, how important is it to 10 us in the future, if we don't reprocess our spent fuel from 11 nuclear power plants? This only arises because of the 12 reprocessing, or it only arises because of the enrichment of

() 13 uranium claimed through reprocessing of spent fuel.

14 Several people that I was discussing this matter l

15 / with said, well, even if we reprocess spent fuel, instead of I

16 I putting the reclaimed uranium back into the gaseous I

i 17 ! diffusion enrichment process, why don't we set it aside and 18 l enrich clean raw uranium and blend the two out over here I

19 l somewhere? Then you wouldn't have the technitium within 20 your gaseous dif fusion plant.

21 So the subject has ramifications and implications 22 far beyond its immediate appearance.

23 I asked myself, too, why don't they use the metal 24 to make nuclear submarines? The NRC news release of March

() 25 14, 1986, said that federal guidance would be issued on ACE-FEDERAL REPORTERS, INC.

202 347 3700 Nationmide Coserage *n34fM6

6300'01 04 5 l' this. Well then, the more I read, I gathered that the EPA

{ { DAVbw 2 is the'one that is responsible to develop the guidance, and 3 then one of the NRC memos -- I believe it was Dircks memo of ,

4 November 25, '85, had a draft letter in it, as I recall, 5 addressed to EPA, and it would have been about the third 6 letter to go to EPA, saying, we're ready to help develop 7 this guidance.

8 Well, I would like'to know where that guidance 9 stands. Of course, that is why the NRC Staff is here today, 10 hopefully to help us.

11 MR. EBERSOLE: Where was that incident where the 12 metal came from Mexico? How did that sneak out? How was-() 13 that processed?

14 DR. MOELLER: It is part of the same generic 15 problem. It certainly wasn't from the reprocessing. It 16 wass a contaminated cobalt 60 thing.

17 Yes?

18 DR. PARRY: It actually was a source that had 19 been inadvertently included in scrap.

20 DR. MOELLER: I am saying it is kind of an 21 overall problem of recycling or having contaminated f.

22 materials out in the public domain.

j 23 MR. EBERSOLE: You were talking about really i

24 gross removal of the surface, some surface fraction, before

() 25 the smelt it.

6300 01 05 6 f~') 1 DR. MOELLER: We will hear more about it this v DAVbw 2 ,

morning, but my understanding is that the technetium -- you 3 see, when you extract uranium and plutonium in a chemical 4 processing plant and separate it from the fission products, 5 the technetium goes with the uranium. It is not a clean 6 separation or, you know, some of it goes in the uranium.

7 When you take that depleted uranium and put it back into the 8 gaseous diffusion plants to re-enrich it, you spread 9 technetium throughout the gaseous diffusion plant. Then 10 when you replace components and so forth within the 11 diffurlon plant, you spread the technetium around.

12 Now the reason they smelt discarded components O)

( 13 l from the gaseous diffusion plant, the reason they smelt 14 them is that they are in configurations that are classifiede 15 and they don't want people to see them in these shapes and

. 16 forms, so they smelt it, so you won't recognize it.

17 DR. MARK: Another cost-benefit for 18 classification.

19 Do they really recirculate the depoted uranium 20 very much?

21 DR. MOELLER: I don't know. Maybe when we talk 22 to the Staff, Don Hopkins may be able to help us.

I 23 MR. EBERSOLE: Isn't gaseous diffusion going into 24 history anyway?

D

(_). 25 DR. MOELLER: It may be, but that, to me, those ACE-FEDERAL REPORTERS, INC.

4 6300 01 06 7 '-

1 are questions that I would like to see answered, but if we (7q) DAVbw 2 look at it in its broader implications, that becomes less 3 important.

4 DR. SHEWMON: If the plants go into history, this 5 will be more important than every before, because we've got 6 to decide what to do with it.

7 DR. MOELLER: Our goal on this will be, if we can 8 do it, to develop and make some recommendations, as a 9 subcommittee, to send on up to the full committee to see if 10 the full committee is willing to take a position on it and 11 make some recommendations.

12 So I think we are in a position to give it an

( 13 objective review and see if we can offer some constructive 14 ideas.

15 Jack?

, 16 DR. PARRY: I would like to mention that I think 17 that this is part of the generic question about de minimius I

18 as part of the Low Level Waste Policy Act, and it is 19 included, even peripherally in the mixed waste question that 20 the Commission is also facing.

21 Respectfully, I'd suggest that the subcommittee 22 may start considering or thinking about de mimimia. That is 23 going to be a question that will arise fr-, the Savannah 24 River Plant's decontamination of their sludges, and so 25 forth, and a question that is going to be coming across ACE-FEDERAt.

'( DAVbw' I more'and more.

2 DR. MOELLER: Okay. Then the second item we will-3 cover today is reviewing the waste management research 4 program within NRC. And in particular, we want to be 5 brought up on the implications and.the impacts of the Low 6 Level Waste Policy Act of.1985. The committee, I' hope, will 7 hear or at least maybe we can schedule a discussion of this 8 at the upcoming full committee meeting, because I don't 9 think the ACRS, as a body, as yet recognized that there are

- 10t low level waste questions and problems for us to address as 11 a result of this Low Level Waste Policy Act.

12 I think there are considerable questions and

() 13 problems to be addressed.

14 Now supplementing the discussion of the Low Level.

15 Waste Policy Act, there are-two items. The first one wo 16 must address in.this meeting.and the second one, again, I 17 hope we can begin to address. The one we must address is 18 that on May 9, the RSK from the Federal Republic of Germany 19 will be here, a representative group, and they want to 20 discuss with the ACRS certain questions, three questions,

21. related to high level and low level waste management. I 22 have draf ted some written comments on each of these three 23 questions which will shortly be distributed or distributed 24 at the appropriate time. They are done in a hurry. They

() 25 are not complete. They are probably not even accurate, but ACE FEDERAL REPORTERS, INC.

6300 01 08 9

( ) DAVbw 1 they will serve the basis for formulating some thoughts on 2 each item.

3 Here are the three questions.

4 How do the release limits and the dose limits and 5 the associated risk for a high level waste repository 6 compare to that of a low level waste repository and how does 7 that compare to a nuclear power plant or other types of 8 nuclear facilities?

9 MR. EBERSOLE: Boy, that is potent!

10 DR. MOELLER: Well, I have answered it in my 11 written response.

12 (Laughter.)

(~h

(_) 13 DR. SHEWMON: Is this a comparison of risk to 14 both?

15 DR. MOELLER: A little bit of everything.

16 What are the release limits? What are the dose 17 limits? And how do they compare riskwise? And I even threw I

18 in there, which I didn't address -- I threw in uranium mill 19 tailings. I think it would be fun to look at them and see 20 how they compare.

21 DR. MARK: Aren't the limits for high level 22 and low level actually different?

23 DR. MOELLER: Yes, and they are formulated in a 24 different way.

( 25 DR. MARK: Both by EPA.

6300 01 09 10 DAVbw 1 DR. MOELLER: Right.

2 DR. MARK: By two different branches.

3 DR. MOELLER: And we have to talk about it, you 4 know. If we can just be sure we know what the existing 5 situation is.

6 DR. STEINDLER: Did you leave out, for example, 7 hazardous chemicals?

8 DR. MOELLER: We didn't consider that.

9 You were saying this would be a thick document.

10 Frachlo said do it in six pages, which made my job easy.

11 DR. SHERMON: We ought to put a little 12 technetium in that r 13 MR. ERERSOLE: This is going to be a classic and 14 system integration.

15 DR. MOELLER: The second question is, how do you i

16 evaluate the performance of a high level waste repository 17 and a low level waste disposal facility? If you use models, 18 how are they evaluated? How are they confirmed? How are 19 they validated?

20 We are going to talk about that tomorrow, so we 21 will have some input there.

22 And the third cuestion was, what are the 23 environmental radiation surveillance requirements for a high 24 level waste and a low level waste facility? Are they

/

~

N, 25 different for the preoperational phase, the operational

(>

  • e p

m .

6300 Ol'10 11 phase'and the post-closure phase?

( DAVbw 1 2 'Then, of course, the major question, which you 3 -hrve already mentioned is, what do we do about radioactive 4 wastes-that also contain toxic chemicals, and see, in the 5 Low Level Waste Policy Act of 1985, the Congress said they 6 were not addressing that question.now, but they would 7 address it early in 1986. So hopefully, they will offer 8 same guidance.

9- MR. EB EP. SOLE : To whom would you address these 10 que stions now, Dade?

11 DR. MOELLER: These questions are questions by 12 the RSK that we have agreed we would discuss on May.9th in

() 13 the full committee meeting.

14 MR. EBERSOLE: At whom would you point them in 15 real life, these questions? Congress? NRC?

16 DR. MOELLER: Yes. EPA, NRC, DOE. We all have 17 to know the answers.

18 The second item under waste management that wo 19 want to begin to discuss today is one that Jesse Ebersolo 20 has laid on our platter, and that is to try to develop a 21 statement on risk perspective, in terms of a high level 22 waste repository. In other words, how does it compare to 23 other nuclear facilities?

24 I think what Jesse was trying to do was to have a

() 25 statement which would help not only the committee, but ACE-FEDERAL REPORTERS, INC.

[ ) DAVbw I would maybe even be useful, in terms of the general public, a

2 in understanding the difference in the nature of the risks 3 associated with the high level waste respository versus a 4 nuclear power plant.

5 Now I prepared a quick draft of generalities on 6 this subject.

7 Jack Parry, then, did a much more detailed --

8 although he called it a qualitative asessment, he did some 9 very good quantitative assessments within his statement.

10 That has been distributed.

11 And then, since Jack pointed .ut some errors in 12 mine -- you have not seen it? Am I wrong that Jack Parry's (n),

13 thing has not been distributed?

14 DR. PARRY: It went to the subcommittee.

15 g DR. MOELLER: We will run it off and see that ou 16 l get it.

17 We will distribute it at noon, say.

18 i So after Jack showed me the errors in my 19 write-up, I went back and corrected it so it wouldn't look 20 so ! ad, and I am going to distribute it.

21 DR. REMICK: They are not errors. They are just 22 ways of possibly improving.

23 DR. PARRY: I object to the terminology here.

2 I used the word. There is no deadline on that. It is quite 3 possible, all we can do in this meeting is barely touch it.

4 Tomorrow, we will first address the high level 5 waste modeling strategy document prepared by the NRC Staff 6 for evaluation and assessing performance of high level waste 7 repository. Then we will wrap up the meeting with a 8 discussion of the OA requirements, in conjunction with the 9 construction and operation of a high level waste 10 repository.

11 Whether we will need or desire to issue a formal 12 report on the OA portion, I personally look to Forrest (Oy 13 Remick to offer us guidance on that, since he chairs the 14 ACRS OA Subcommittee.

()DAVbur 2 this meeting. IIe is seated on my right.

3 The rules for participation in the meeting have 4 been announced as part of the notice published in the 5 Federal Register on April 2nd, 1986.

6 It is requested that each speaker first identify 7 herself or himself and speak with sufficient clarity and 8 volume so that he or she can be readily heard.

9 We have received no written comments or requests 10 for time to make oral statements by members of the public.

11 Let me then before we proceed with the mooting 12 ask if there are any subcommittee members or consultants

() 13 that have comments or questions at this time.

14 DR. CARTER: Dade, I have just got one comment.

15 I It is sort of interesting to read this material, which goes 16 back over a long period of time. We have obviously had a 17 problem of contamination by radioactivity on a number of 18 things for 40-odd years or so.

19 It is sort of a paradox for me to see all the 20 statements in here, that we are going to pursue this on a 21 vigorous basis, and so forth.

22 Just a comment.

23 DR. MOELLER: I think that comment is very 24 appropriate. I believe also we probably should take it into

, ( 25 account when we criticize, you know, some of these documents Acti-Fliot!RAL Ri!PORTiins, INC.

3 DR. CARTER: They are historical documents.

4 DR. MOELLER: Any other comments?

5 (No response.)

6 DR. MOELLER: We will proceed with the meeting.

7 We are going to first then address the subject of the 8 salvaging of smeltered alloys.

9 We have with us Don flopkins, from the NRC 10 Research staff, and David Baker, from Pacific Northwest 11 Laboratories.

12 Don.

() 13 MR. ItOPKINS: Thank you, Mr. Chairman.

14 My name is Donald flopkins, from the Office of NRC 15 Research. I am the present task leader for the smeltered 16 alloy tas<. I am the sixth task leader for that task 17 throughout its history.

18 I have with me on my left Mr. David Baker, from 19 the Pacific Northwest Laboratories, a professional engineer 20 who has long experience in the preparation of environmental 21 impact statements.

22 lie was the main contact and task i;ader for the 23 development of the draft environmental statement on 24 smeltered alloys, which was made available to the public in 25 1980 and corresponded to the proposed rule which we issued l

2 I am afraid we are not going to be able to answer 3 -all the questions you had to ask. You have a multitude of 4 things that cover a very wide span. We are prepared to talk 5 about the smeltered alloy rule and the draft environmental 6 statement in detail.

7 If you do get into the follow-on ef fort, the 8 development of standards for recycling contaminated scrap 9 and the coordinated effort with EPA,-we do have Mr. Donald 10 Harmon in the audience, who is participating in that 11 effort, and he may be able to answer some of your 12 questions.

( )' 13 DR. MARK: A question of mine, when you talk of 14 smeltered alloys, are we to think almost entirely of steel 15 or are there other materials that come to mind?

16 MR. HOPKINS: In the particular effort we are 17 involved in, it is the result of an upgrading of the 18 Department of Energy's uranium enrichment facilities. It 19 includes the scrap metal which was produced as a result of 20 -

that effort. It includes not only steel but nickel, copper, 21 aluminum as well.

22 So those are the specific things that are 23 discussed in the draf t environmental statement.

24 DR. MARK: Now, you mentioned four important

) 25 commercial metals -- nickel, copper, aluminum, and steel.

2 MR. HOPKINS: In this particular rulemaking, 3 yes.

4 DR. MARK: But in the real world nituation?

t 5 MR. HOPKINS: Let me refer that to Mr. Baker.

6 MR. BAKER: I would say primarily that would be 7 the major metals. Certainly you are going to have some 8 minor constituents in nuclear reactors, and so on, that you 9 could recycle. Gold, for instance, you might want to 10 recycle.

11 DR. MOE L'LE R: There have been examples of burns 12 on people's fingers from wearing recycled gold rings. ,

() 13 MR. HCPKINS: The recycled nickel is the main 14 component of the smeltered alloys we have considered as far 15 as the value is concerned. Nickel overwhelms all the rest 16 of it, and if my understanding is correct from other more 17 generic studies that I have seen, steel would be the main 18 component coming out of the nuclear reactor decommissioning 19 effort.

20 DR. MARK: Thank you.

4 MR. BAKER: The nickel was smeltered for that 5 reason, only the nickel. The steel and copper -- the copper 6 was windings, motor windings, and the steel is just steel, 7 and this was not sm sitered.

8 MR. EBEFSOLE: I just thought I would mention the 9 problem in smelting of achieving a homogeneous mix,.whether 10 or not that is any longer important to smelt simply.

11 MR. BAKER: I couldn't answer that at this time.

12 MR. EBERSOLE: Sometime it might be important.

() 13 MR. HOPKINS: I think tno smelting in this case 14 was not dono strictly for classification purpoues. It was-15 done to extract some of the impurities, radioactivo 16 impurities from the materials.

17 MR. BAKER: There were two reasons. It was a 18 good way to got rid of the classification as well.

19 DR. SHEWMON: A very handy way to consolidato 20 things and make sure you know what the average content is.

7 Where did they get the technetium, and so forth?

8 DR. SHEWMON: They also say they aren't sure of 9 the contamination level out in Nevada.

10 MR. BAKER: We put that in there just to show 11 that this is the amount of metal that we have in the DOE 12 inventory.

5 DR. MOELLER: I agree. I think we can learn the 6 details of this particular problem, but we do want to keep l 7 in mind the broader range aspects. That is what we want to 8 address.

9 DR. STEINDLER: The point you raised concerninq l 10 cleanup prior to smelting and cleanup during or after 11 smelting is somewhat dependent on the type of 12 contamination. Technetium is one thing. Uranium is j 13 another. Pission products, mixed or otherwise, are a 14 third.

15 Some of them are intractable, in the sense that 16 they don't remain as oxides. They can reduce and become l 17 alloys at that point, and 11fe gots somewhat more difficult, I

18 especially since you are dealing with material that has 19 essentially no value. It is a waste product.

20 DR. MOELLER: Excuse me. It could well be that i 21 our conclusion -- and I am jumping ahead -- but it could bo l

l 22 that our conclusion this morning will be that we need to 23 schedule a meeting, have EPA come over and tell us what f

2 Jesse mentioned the cobalt-60 Mexican incident, but that is 3 a whole other kettle of fish. It is totally different. The 4 source of the proll m is totally different. It is a 5 five-year halflife versus 210,000 years, or whatever 6 technetium is.

7 So it is to me totally a different problem.

8 DR. STEINDLER: Let me suggest that in the modest 9 lifetime of an industrial chunk of material it may not be 10 all that different, especially if the source to fairly 11 high. Five years is an uncomfortably long halflife for 12 something that is trivial in relation to, say, technetium.

6 DR. MOELLER: Good.

7 MR. HOPKINS: To begin with, the events which 8 precipitated our consideratio.n of the smelted alloy recycle 9 request was the fact that the Atomic Energy Commission in 10 its enrichment plant operations went through an upgrading of 11 those operations and replaced a large number of the 12 components metals.

(o,) 13 The metals which were replaced then became scrap 14 metals, but were found to be contaminated, not only with 15 uranium but with technetium-99, a product which originates 16 from a byproduct of the reactor process which was introduced 17 into the enrichment process.

18 In recycling of uranium back through the 19 enrichmust process, DOE recognized that the very large 20 quantities of contaminated scrap, to do something with, it 21 should consider within its own confines what it should do 22 with that, and it recognized that it had several options.

23 Some could be used internally. It could be 24 recycled to a particular place perhaps for the manufacture

( j DAVbur 1 What they chose to do was to try to decontaminate 2 the scrap metal to the extent that they could, to then smelt 3 it, to extract whatever it could in the way of contamination 4 that was left, assure that it was below'certain limits, and

. 5 to re.:ycle it into the general economy.

6 This eventually presented a problem, as you may 7 know, in that when you recycle it into the general economy 8 it can go anywhere, into personal items or consumer items..

9 -In February 1974, the AEC operations asked the

_10 AEC regulatory side to establish some de minimis 11 quantities. They wanted these de minimis quantities of 12 course-to include quantities to which they could

() - 13 , decontaminate the scrap so they would be able to use the de 14 minimis quantities to be able to put the scrap out into the 15 general commercial process.

16 In the following month, March 1974, there was a 17 favorable response from AEC regulatory.

1 18 The problem at the time, there was already an

{ 19 exemption in the regulations for contaminated uranium, 20 uranium whether it is contau.inated or part of ores perhaps.

. 21 This exemption applied to natural or depleted uranium, and 22 that exemption still exists in the regulations.

23 It would have been sufficient to cover-these >

3 So it didn't qualify under the existing exemption 4- which was for natural or depleted uranium only, and we had 5 no authority at the time to' offer an exemption for enriched  ;

6 uranium. The act forbade it at the time.

. '7 But in a very short period of time Congress was 8 expected to act to change the Atomic Energy Act to allow us 9 to have exemptions.for special nuclear material.

So the AEC 10 favorable response included reference to that Congressional

! 11 action and anticipated that it would be favorable and that 12 we would be able to go ahead with the exemption.

l( ) 13 Anticipating that AEC regulatory would go ahead 14 with the exemption, the operational side of AEC promised to 15 produce an environmental impact assessment which covered 16 what the benefits and derogatory parts of recycling of this 17 contaminated scrap would be, and they contracted -- they, 18 AEC operations -- contracted with ORNL to produce this 19 environmental impact assessment.

20 It was produced and provided to us in September 21 1976, a little over two years later after the favorable 22 response from regulatory.

23 On receipt of this environmental impact

'24 assessment from ORNL, the regulatory group, which was NRC by

() 25 that time, decided it needed an environmental impact ACE-FEDERAL REPORTERS, INC.

{- 17 comments and some legal questions raised about the draft 18 environmental statement and the proposed rule, actually

19 mostly about the proposed rule in my perusal of the history 20 of this thing, but these were apparently all overcome 21 because there was in the end concurrence by all NRC offices l 22 in the proposed rule which went to the Commission.

23 In July 1979, there was a follow-up request by 24 the Department of Energy in which they identified that they I

( .1 2 like to recycle into commercial channels and they had use 3 for that money.

4 In September 1979, we had an internal memo 51 requesting concurrence in the proposed rule. At the same 6 time we distributed the proposed rule in the draft 7 environmental statement to all the agreement states.

8 I.saw no record of a response from the agreement 9 states, which either means that none responded or that they 10 all responded and had clear responses, 11 In August 1980, SECY 80.384 was sent to the 12 Commission, recommending that the Commission approve the j I 13 proposed rule for exempting these materials, which were in 14 fact the DOE smelted alloys but they weren't identified as 15 such.

16 Management had made a decision that we should not 17 be in a position to publish an exemption which benefitted 18 only one group. So the exemption was written so that other 19 people who had similar materials would find that they were 20 also exempted, although we knew of no similar materials, 21 certainly not in large quantities.

22 The Commission approved the paper 3 to 1, with 23 Commissioner Bradford dissenting.

24 The proposed rule was then published in the ,

() 25 Federal Register in October 1980, and the availability of ACE-FEDERAL REPORTERS, INC.

3 The correspondence in the file shows that we made 4 800 copies of the draft environmental statement, and of 5 course we distributed it to all the federal agencies a concerned and how many of the additional ones were sent'out 7 there is no record of.

8 There are very few left. There are some 40  ;

9 available in our system. So apparently most of those 800 10 copies of the draft environmental statement were 11 distributed.

I 12 The present situation is a little different from r^%

(,) ~ 13 what I had thought. I thought all of the metals had been 14 smelted and we were waiting for a decicio , but in recent

} 15 checking I find that the nickel part of the contaminated 16 alloys has been smelted, for two reasons:

s 17 One is because they claimed that it had a 18 classified configuration and they needed to get rid of that 19 classified configuration.

20 Tpe second is that it is by far the most valuable i .21 of the metals which they had, and they were looking forward i 22 to being able to reclaim that value.

, 23 DR. MARK: What is the contamination in nickel? ,

7 components.

8 The only other thing which has been done with 9 these metals to date is that the steel has been sized. From 10 the very large pieces that were initially available they 11 have cut it into smaller pieces so that it is handle-able.

22 that was happening and also in view of the fact that there 23 were several other requests for similar exemptions, that 24 what was really needed was not an ad hoc approach to each of

() 25 these requests but a concerted, coordinated approach, not i.

-7 in deference to this development by NRC and EPA of national 8 standards in this area, 9 DR. CARTER: But you have a draft final report.

10 That is an internal document?

11 MR. HOPKINS: An environmental statement, draft 12 final, yes.

3 MR. HOPKINS: The question was when did the 4 technetium get introduced into the gaseous diffusion 5 process?

6 DR. CARTER: When was it introduced or when was 7 it cleaned out?

8 MR. BAKER: We assumed it was in there all the 9 time. For this document we assumed it was at 5 parts per 10 million technetium.

-11 DR. CARTER: That is an assumption?

12 MR. BAKER: As far as I know, that was what was 13 in there.

14 MR. IlOPKINS: Based on information that DOE gave 15 us, of course.

16 DR. MOELLER: Again, you know, we are not holding 17 a classified meeting. It is open to the public. But I j 18 immediately have some of the same questions.

19 I presume, though, that a lot of this technetium 20 in our gaseous diffusion plants results from military fuels 21 that have been reprocessed, or is it from commercial fuels?

i 22 DR. STEINDLER: There hasn't been that much in 23 the way of commercial fuels.

6300 03 12 39 1 MR. EBERSOLE: I can understand the first reuse

5 MR. BAKER: We assumed that, yes.

6 MR. EBERSOLE: You really lose control of it? ,

p 7 MR. BAKER: That was the whole idea. You just  ;

8 release it into the commercial marketplace.

9 MR. EBERSOLE
It couldn't be oriented into the 10 waste program itself?

11 MR. BAKER: That was the second tack we took in

() 13 limited to releases in the amounts for objects that were not 14 personal items.

15 See, this was the big problem with all the 1

16 comments that came back, was that we had released this stuff 1

17 and there were no restrictions whatsoever. That is the 18 whole idea, i

9 M2. BAKER: It would be a very small amount 10 considering, but you could use it that way.

11 DR. MOELLER: Richard and Mel and Jack.

12 DR. POSTER: I gather that the original request

() 13 from AEC/ERDA was that these materials be added to an 14 already ext. sting list of exempt materials which now appears 15 in 10 CFR 70 and Table A in here, which has got a fairly 16 extensive laundry list of nuclides and concentrations which 17 are exempt.

18 My question is: is this particular proposal or 19 addition to that list the first that came along after the 20 NEPA? Is this the first one that required an impact 21 statement and public comment, and therefore it is unique in 22 that sense, or is there something else that is unique about 23 it that we certainly have comments?

-6300 04 01 42-j()DAV/bc 1 MR. HOPKINS: Much of what you say is true, but 2 there was no existing Part 70 list because we were not 3 allowed to have exemptions of special nuclear material up 4 until this time in 1974, when the Atomic Energy Act was 5 changed.

6 So there was no existing list to add this to.

7 The existing exemption was of natural and depleted uranium.

8 Thnt would have been in Part 40. We couldn't put an 9 exemption in for enriched uranium in Part 40, you had to go 10 into Part 70.

11 The technetium exemption would have gone into 12 Part 30, and there is an existing list of exempt material h 13 there.

14 So, for the enriched uranium, this would have 15 been the first.

16 DR. FOSTER: Right now, the regulation is 10 CPR 17 Part 70. It does have an exempt list.

18 MR. HOPKINS: But it couldn't have then because 19 we weren't authorized to.

20 DR. POSTER: Where did the existing one come 21 from?

() 13 this entire thing that you've got all of these metals, 14 hundreds of tons of them scattered around various DOE sites 15 or facilities. They've been there a long, long time.

16 The question is, has any of this material ever 17 been put in commercial circulation? How would you know that 18 it's not been?

19 MR. BAKER: Probably, unofficially, I suppose it i I

i. 20 has because the workers take back stuff and sell it, and so 21 on. So I imagine quite a bit is in circulation in 22 facilities. In fact, I ran into a personal case of that; it-i 23 got dumped on a fellow's real estate.

f)l

%- DAV/bc 2 DR. SHEWMON: Let me ask a little bit about.

3 that. It's not my impression that DOE operates live mills 4' for making stainless steel. So when you say they can use it 5 within their system, do you mean that they could give.it to 6 a commercial supplier of stainless steel to use in his 7 melting operation, or do they mean they'd have to set up 8 their own casting and forming operation?

9 MR. BAKER: I've discussed this with other people q 10 quite a few years ago. And the idea was to not make 11 stainless. If it was recycled within DOE, you could make 12 something crude, you know, that you could use. You could i

() 13 put a small plant there and you could smelt it up and make 14 something. You could make molds out of.it, or something.

15 DR. SHEWMON: Smelticg is relatively easy.

4 16 Making it into complex shapes and alloys is a good deal more 17 sophisticated and expensive.

{ 18 MR. BAKER: Something they could just mold, or 19 something, and have your object there with a limited amount 20 of processing.

21 DR. SHEWMON: And you think DOE uses tonnages of 22 these sort of products?

23 MR. BAKER: One is these hammers or balls you j 24 could crush ore with, and you'd just make these balls up.

4 MR. BAKER: That's one of the ideas.

5 DR. SHEWMON: Those crude things are reasonably 6 sophisticated alloys.if they last very long, and they don't 7 have a lot of nickel in them, but go ahead. You know.

8 MR. BAKER: That was one of the ideas.

9 DR. SHEWMON: For useful products, DOE is not in 10 the business of manufacturing them, so I don't see that --

11 DR. MOELLER: --as a viable alternative.

12 MR. BAKER: That's why we didn't push it at the (J- 13 moment. This wasn't one of the alternatives that was 14 pushed.

15 DR. SHEWMON: But it's not to'a controlled 16 supplier. They could not say: Give it to Allegheny-Ludlum 17 and say use this in the next batch.

18 MR. BAKEk: No. It would have to be within the

19 site itself.

1 20 MR. HOPKINS: If I could continue, maybe the next 21 thing will shed some light on your problem.

22 In addition to recycling with its own facilities, 23 and recycling, not how it gets into recyclable shape, the i

24 DOE could work with people in the commercial sector through

() 25 air-licensing program without the need for an exemption, and ACE FEDERAL REPORTERS, INC.

5 If you could license that person to take the 6 DOE's waste _ scrap and smelt it with whatever controls are 7 necessary to go along with the process, and you could give 8 it back to DOE in whatever shape it wants, that involves 9 only one licensed operation and does not involve any of the 10 recycling into the commercial sector.

11 DR. MOELLER: I guess that raises the question i 12 that Jack-Parry has mentioned to some degree. Let's say you j ) 13 license this commercial group and they made whatever they i

i 14 made -- stainless steel, or something, out of it -- then 15 what about the next batch that goes into those same vats, et i ~

10 One thing that I failed to mention in my earlier 11 presentation was that there were separate comments received.

12 on the rule. The rule, we received 3,700 comments on; there

3 We have a summary which included a discussion of 4 the alloys which we were going to discuss, and which were i

5 stated to us as being part of the materials which we would 6 release into the general commerce.

4 7 We discussed a description of the scrap and its 8 possible decontamination methods and the smelting and what 9 the reductions would be in smelting of the uranium and 10 technetium.

11 Our economists discussed the market for the i

12 smelted alloy and estimated what these markets would be in

() 13 the-future. They foresee it might be quite different now 14 than what they wore extrapolated to be, i

15 We covered the predicted impacts of the smeltered i 16 alloys. These impacts were during the manufacture and so 17 on. We discussed the radiological impacts and the societal.

18 impacts.

j, 19 On our radiological impacts we included about 20 anything that you could make out of these materials and,' as r-21 I said before, we included very personal items at the time.

22 This metal would be released with no restrictions 23 whatsoever on what it would be used for. Therefore, for 24 ccs, bone pins, things like this, jewelry, very personal

7 Now, quite a few years have passed and we think a 8 little differently now about this. -Some of it, I think, is 9 a little hindsight because we now have this ALARA principle 10 that we're sort of looking at. And, hopefully, we sort of 11 feel that's the way we should look at it.

}DAVbw 2 dealt mostly with uranium and give you less than the numbers 3 in the original context. It doesn' t mean a thing' to answer, 4 ~at least to me.

'5 DR. SHEWMON: On page 213. there is a mass 6 balance that includes technetium. It actually says it ends 7 up in the unit. Nickel melts at 1450 C, as I recall, give 8 or take.

9 DR. MOELLER: If you believe that table.

10 MR. STEINDLER: I couldn't check it, because I 11 couldn't get hold of it.

12 MR. BAKER: We had that reference.

13 DR. MOELLER: While we are in Chapter 2, on page

.l( )

14 2-3, TaLle 2.3, you give-the quantities of copper, steel, et 15 cetera, that you anticipate in scrap metals for BWRs and 16 PWRs and how much technetium is going to be in that metal.

17 I ask, because my presumption is, none. So I find the 18 comparison, or I find the table of little use.

19 MR. BAKER: We took it out in the final, because 20 it was just put in there for comparison or something How 21 much metals we think would come out of the commercial power 22 reactor program. We did not state here what radionuclides 23 these metals would be contaminated with.

24 DR. REMICK: A question. I wasn't quite clear in

2 go to the point of no technetium, no uranium, but I am not 3 sure what you did. You said something about ALARA.

4 MR. BAKER: I imagine, if we had the final here 5 to read, some of the discussion, that was one of the 6 comments that EPA had. We didn't hold by this ALRA 7 principle.

8 DR. REMICK: What would it be in a case like 9 this?

10 MR. BAKER: You could go to the extreme. ALARA, 11 you try to get a balance here, and you don't go to one 12 extreme or the other. The balance point is more or less

where the climate of opinion is, I suppose. Therefore, we 14 I looked at it as it would be reasonable to recycle this 15 l material into something that would never get into personal 16 public use. ,

17 DR. CARTER: Dave, let me ask you a question that 18 relates to Forrest's comment.

19 In Table 1.1, on page 1-4, most of those 20 exposures that have been calculated, you know, are fairly 21 innocuous, but there are two that aren't. One is the skin 22 dose over a 50-year period. The other one, though, is a l

l 23 bone dose, which is 20-rem in 50 years. That is over i

24 400-millirem per year. Then if you compare that, even if l

6300 05 03 58 1 but you've certainly come pretty close.

}DAVbw 2 MR. BAKER: I realize that.

3 DR. CARTER: Certainly, I would think that bone 4 in this case is a critical organ, at least my bones would 5 be.

6 So that sort of thing, it would appear to me, 7 certainly, there is no saving grace about having a bold 8 implant made with radioactive material versus no radioactive 9 material.

10 Have you done anything? Are those calculations 11 on that sort? Have they been looked at again? Checked, or 12 whatever?

I) 13 MR. BAKER: Actually, then we pulled back, as I 14 said, and it was more or less academic, because we weren't 15 going -- this license would not be for releasing this into 16 this type of marketplace.

17 DR. CARTER: Because obviously, in this case, if I

18 you're concerned with a change in the quality factor, you're 19 obviously over the criteria. So historically, this could 20 change considerably. I dare say these numbers would look 21 quite different, if these calculations were made today. The 22 numbers would be considerably higher.

23 MR. BAKER: As I say in hindsight, this looks 24 sort of fishy. I realize that.

6300 05~04 59 1 thought, look on page 4-22. At the top of the page, Table

(}DAVbw 2 4.14, it's a table of how it affects risk factors, and it 3 says " Type of Risk: Cancer from total body exposure."

4 Okay. Even if you took that as fatal cancers 5 from total body exposure versus just simply morbidity and 6 ' mortality, you would get a higher number. You have here, it 7 is 50 x 10 to the -6 per rem. Well, it is actually 2'x 10 8 to the -4, 200 x 10 to the -6, and if the Japanese -- and of 9 course, you didn't know about this at that time, but if the 10 recalculations of the Japanese survivors doubled the risk, 11 you are talking 400, but even with 200, you are of f by a 12 factor of 4 from what is commonly accepted today. And this 13 (f report is published in 1980, and ICRP was certainly out. 26 14 was published in 1977. So I did not understand that number 15 at all.

16 MR. BAKER: Which number?

17 DR. MOELLER: The 50. If I a reading it right, 18 it is 50 x 10 to the -6, and it should be at least 200 x 10 19 to the -6.

20 DR. CARTER: I think this the thing that I was 21 commenting on. These_ numbers have just changed. The 22 quality factors have changed. So not only are the criteria 23 allowable if the standards change, but obviously, the 24 numbers themselves change. It is very difficult, when you

3 DR. MOE LeR: That i= why we really need to see 4 the update. On page 6-2, you imply, at least as I read it, 5 that it is okay to bury 210,000 year half-life material in a 6 shallow land disposal system.

7 Is that what you are implying?

8 MR. BAKER: We were lookino -- one of the 9 alternatives, as I remember, was looking at that surface 10 burial.

11 DR. MOELLER: Nell, you bury it there.

12 Okay. Jack has a comment.

y 13 DR. PARRY: I think, actually, at these 14 contamination levels, these would be Class A, low level 15 waste, and would be subsumable for surface burial. If you 16 want to make another point, following up on Marty's comment, 17 it appeared to me -- and I realize this is some years back, 18 this data, for instance, on 213, represents single tests, 19 and we really don't know what the behavior is going to be, 20 other than based on single experiments.

21 MR. BAKER: Small scale tests.

22 DR. STEINDLER: Not only are they small scale, 23 but they are atypical in other ways. For example, that 24 test on the nickel barium material was done without a flux.

}DAVbw-2 DR. MOELLER: Mel?

3 DR. CARTER: I wonder if Dave could comment on 4 the fact that the exposures are related to the degree of 5 enrichment of the uranium.- The statement is made in 6' ~ Appendix A-2, for example, that if you release a larger

7. quantity of material, for example, than that above, say, 1.5 8 percent enrichment in the doses that are calculated in this 9 Draft Statement, maybe an order of magnitude more. That was 10 certainly pretty close to the old limit.

11 DR. MOELLER: Say that again, Mel. 3 12 DR. CARTER: Apparently, the degree of

() 13' contamination depends upon the degree of enrichment. Since ,

14 we_do this a little differently at each of the enrichment 15 plants, presumably it makes a difference where this material 16 comes from. The source can be related to the level of 17 contamination. -This is made, by the way, on page A-2, at-18 the end of the first paragraph. Therefore, if a-large 19 quanity of metal contaminated with uranim or greater or 20 1.5 percent enrichment is released, dose to the public could 21 be up to an order of magnitude higher than those reported in 22 Chapter 4.

12 DR. MARK: It ought to be measured in curies 13 then.

14 DR. CARTER: An order of magnitude would make 15 those numbers look a lot different.

16 DR. MOELLER: Well, I was trying to summarize, ,

17 you know, where we stand, and I will offer some comments, 18 but while we are still talking about this report, I notice ,

19 on page XIII, in the foreword, it says that the National 20 Environment Policy Act states -- this is the second 21 paragraph -- that it states, among other things, you know --

22 it is the continuing responsibility of the Federal 23 Government to do certain things to the end that the nation 24 may -- in the last bullet -- that the nation may " enhance

f 3 I hope when you. redo it, that you get a few of 4 -those things out. It seems to me, then, where we stand is 5 as follows. Let me offer some comments to establish the

.6 subcommittee's position. Then we will go from there.

7 Number one, we really need to see the updated 8 Environmental Statement, and we would particularly look at 9 a) the newer dose limics and b) hopefully, the updated risk

-10 coefficients, since they have been used.

, 11 , Number two, we hope for better technical data on i

l 12 which they base their various assumptions, such^as the l ) 13 smelting, where the technetium goes, et cetera.

L 14 And again, with in that, we would look at what

j. 15 Mel just covered, the enrichment of the uranium. If it can
f. 16 be an order of magnitude higher, that is a very serious

! 17 aspect.

l 18 Thirdly, I am just throwing in here that I wish 19 they had looked at what I would call the full range of 20 alternatives, other than what they propose than number two.

l 21 That is the first major thing, to see the updated I

22 Environmental Statement.

23 Secondly, we, as a subcommittee, need to talk to 4

7 Our present budget level in FY '86 and FY '87 for 8 high level waste research is S3 million. It doesn't really 9 permit us the luxury of having any FINS which are relatively 10 more important than any others. They are all the same 11 priority as far as we can determine.

12 In fact, we just went through an exercise, part

7 Bill?

8 DR. MOELLER: Welcome to you, Bill.

9 DR. LOCKE: Thank you.

10 I am going to start with what I think is the last 11 viewgraph in your package. That is No. 13.

12 This cartoon helps because it shows the major

() 13 areas that we have been working in.

14 A disposal system for high level waste is 15 basically very simple. It is working, and there are no 16 moving parts but it does have certain well-defined areas 17 with the characteristics we have addressed.

18 First is the part of the engineered structure and 19 the waste form. Spent fuel will have silicon glass enclosed 20 in some kind of metallic overpack and backfilled with 21 materials. After that you go into the natural host rock, 22 which will be disturbed and thermally influenced for a 23 fairly long period of time because that in a natural process 24 that occurs there. But they are different than are normally

() 25 occurring.

, 1 Then af ter you get out of that area, where there

()DAVbur 2 is a significant thermal influence, you will be in an area 3 .w here perhaps the hydrology is still affected by changes in 4 the rock or other processes but other things are not 5 affected.

6 The temperature is not a primary problem. The 7 process is there. Absorption and groundwater flow through 8 the matrix and the fractures is going to be similar to what 9 it would be in any other system.

10 So our program is divided up into addressing 11 issues in different areas.

12 Now, the first slido in the package talks-about

() 13 our objectivos.

14 The program started out essentially addressing 15 something which is new, and that is geologic disposal of 16 toxic wastes. We had something called the geologic 17 repository, and we nooded to know what makes it work or does 18 not work.

19 Beyond that, could licensing responsibility -- we 20 had no way to demonstrato this, and that is really the crux-21 of the matter, is how we make this thing called a high level 22 wasto depository, how do we make it work, to isolate the 23 wasto for the period of timo that is required by 24 regulations?

3 We all know that groundwater is transported, and 4 we all know that it is designed to meet some short term j 5 objectives. The waste package, how the waste degrades, how 1

6 the package degrades, how it interacts with the backfill

, 7 determines the integral form and species that the waste a comes out.

9 That is what we have to be worried about, not

10 necessarily what is in the waste to begin with. It is what I 11 it produced by the interaction between that regime with its j 12 elevated temperatures and with that backfill and with the O ta cerre te# nreaect -

14 We may have conditions generated by radiolysis.

15 The engineering itself has to function under this altered 16 regime.

17 When you are mining a cavity in your rock system, i 18 you alter the zone around there. Inherent with the static

! 19 stresses is stress relief fracturing, and there are any j 20 number of effects which we are trying to investigate.

9 D R .~ LOCKE: Back to the natural environment. We 10 have radionuclide transport -- disturbance, laboratory 11 measurement techniques, and the coupling of the hydrology, 12 and various things to transport, such as absorption.

() 13 Absorption is a rather major issue as to how you actually 14 include it into the models of transport, particularly in the 15 affected areas.

16 On man-made structures, we're looking at the 17 waste packaging in the environment that we suspect will be, I

18 in '87, we're actually going to have waste packages in 19 salt. We'll look at the design of those waste packages in 20 terms of how they're actually made, and we'll look at the 21 performance of them in a hostile environment.

22 We'll look at shaf t seals, how they're designed, 23 how they affect safety. The next talk, on validation, is 24 going to get into the issue of compliance assurance in more

9 And the basic fundamental concept will determine 10 the calculations and the validation of the process.

11 The next slide is probably what you're most 12 interested in and that is how do we select what we're going

(<m) 13 to do?

14 Well, from what I've gone through just now, it is 15 sort of a talkthrough of problems. You see, we've divided 16 it up into three major areas: thermally-affected areas, the 17- areas of outside thermal disturbance, and the engineered 16 structures.

19 You need to be able to accurately, or if not 20 accurately, at least believably assess the way those systems 21 work. And if they're significantly enough different, then 22 we have to work in all 37 areas.

2 Because of the mandated interaction, there is a

-3 series of NRC/ DOE prelicensing meetings that go on 4 continuously. There's been a hiatus. There's always a 5 hiatus whenever you have to submit something because all 6 their staff are writing madly. So there haven't been a lot 7 of those in recent months.

8 But those prelicensing meetings are supported by f 9 our staff. Our staff is what? About 10 or 12 in high level 10 waste. And that staff, to the best of our ability, and our i

11 contractors cover every major prelicensing meeting. They j 12 participate in the meetings. They give the benefits to the

, -( )

13 licensing staff of their opinions.

14 They interact with DOE personnel. When they come 15 back, if there are significant issues.they have observed at 16 those licensing meetings, then we'll get together, have an 17 assessment and make a management decision on whether a 18 specific recommendation should be made on something en 19 behalf of the relicensing meeting.

20 Other than that, the Division of Waste Management 21 puts out in conjunction with DOE a series of minutes that 22 are distributed to us so we can keep track of what's going 23 on.

24 Needless to say, when these meetings are coming

5 We also have extensive meetings between our staff 6 and the BWM staff when they have technical staff positions.

7 Then we have to check their documents and send them down and 8 schedule meetings for our contractors to come in and 9 interact with the waste management staff. So they're more 10 aware of the issues that our contractors are discovering.

11 The most recent of these was when a contractor 12 whose working on geochemistry made a presentation to the

_ () 13 licensing staff on the state of the art. That's ancient 14 history. I might say thin is not the completion of work on 15 the geochemistry. But it's not his work. He's not 16 available to us, because he had to go to work for the high 17

18 of the program.

5 DR. LOCKE: That's true, but the investigator-6 himself who is being employed to do work which might 7 influence the use of the techniques or processes which he 8 developed at DOE because of something he does with the 9 licensing staff creates a potential inbound bias.

10 In other words, say a contractor at the 11 University of Arizona has developed a saturated zone 12 measurement technology, and he were'to go to work for the

() 13 Department of Energy, and then decided that everything that 14 they were doing was wrong and they had to use the techniques 15 he had developed. A lawyer would look at that and'say, Hey, 16 he's not the guy that should be making that decision because 17 he's got a vested interest in the techniques.

18 His professional reputatio is enhanced by both 19 parties in the program doing it.

20 DR. STEINDLER: I'm aware of the legal 21 arguments. I don't agree with it either the way you state 22 it or the way they state it.

23 The argument is very simply turned around if the 4

There is an 16 agreement, although I do not believe it is a written 17 agreement, but an understanding between both the Division of 18 Waste Management and the Program of Earth Sciences, as well, 19 between the Office of Research and the Office of Nuclear 20 Material and Safeguards, that, indeed, there may, indeed, be 21 reasons for doing some research, even though the user office 22 -- in this case, the Division of Waste Management -- may not 23 feel that it is appropriate or needed and may not support.

24 We have not really had that come up. When there r'; 25 has been some question as to whether or not this research v

ACE FEDERAL REPORTERS, INC.

6300 08.02 95 1 ought to be done, we have usually been able to congregate

(}DAVbw 2 whatever reservations'the Division of Waste Management has

~3 had. Should such a case ever come up, and we feel strongly

'4 enough about it, Mr Minogue would endorse carryimg on with 5 the research.

6 DR. LOCKE: Waste. Management Research,.in 7 particular, is not necessarily presented with something 13 which everybody always agrees on. There are times when the 9 Office of the Division of Waste Management will make a 10 -comment on it in the SOW and say it is not appropriate at L 11- this time. It is not appropriate to this contract. It is 4-12 work that shouldn't be done for any number of reasons, and

() 13 it will go to the Waste Management Review Group and say 14 these are the comments of the Waste Management Review 15 Group. These are the changes that should be made. These 16 are the changes that should not be made, for the following 17 reasons.

18 So it is an interactive process that we do not 19 take lightly. We give them a thorough treatment and we 20 assess them.

~

21 MR. COSTANZI: I war.t to say, even though there f 22 are aspects of approval, this process is fundamentally a i

23 coordination process.

24 DR. MOELLER: I think, Marty, if after they

() 25 finish the presentation, you have specific projects you want ACE-FEDERAL REPORTERS, INC.

6300 08 03 96 1 to raise questions on, you should do that. For example,

()DAVbw' 2 Paul Shewmon raised questions on some of the research here a 3 year or two ago, and we delved into it in depth.

4 Go ahead.

5 DR. LOCKE: I think that takes us to the next 6 slide, which is primarily a time line and another way of 7 looking at the background information that I gave you 8 earlier. It goes 'oack perhaps ten years, when we first 9 began doing the research on high level waste in a 10 significant way. Essentially, it shows the first phase of 11 research is that one in which we are trying to identify.the 12 issues and processes which we need to study, and there is a

() 13 rather discrete line there, which is obviously very fuzzy.

14 We may still be identifying issues even at the time of .

15 licensing, but we are shifting the program now to one which 16 is much more directly aimed at establishing the competence 17 of the demonstration of assurance. -

18 Then, of course, after an extensive period, we.

19 have to address the further issues. Those are issues' raised 20 on occasion, even now, that focus the same characterization 12 1 and licensing and operation.

22 Yes?

23 DR. SHEWMON: I was at the Materials meeting in .

t 24 Columbus a few months ago, and one of the uncertainties, and f 25 thus, contentions there, was the degree to which there will ACE FEDERAL REPORTERS, INC.

6300 08 04 97 1 be pockets of brine that they are likely to bump into or

}DAVbw 2 likely to come in contact with. The overpack, the steel -

3 container, I would call it, that is there.

4 Is there any hope that the site characterization 5 can be in enough detail to find out where these things are 6 or what they would do with it, if they did bump into them?

7 MR. COSTANZI: I would think that, indeed, there 8 is. The DOE has to submit to NRC, for its review, a site 9 characterization plan. Once the sites for characterization 10 are chosen, one of the things that we will do at the time 11 that those are received by the Division of Waste Management 12 is to essentially give all the things that we know, in terms

() 13 of relative considerations, the relative importance of the-14 processes and the characterization techniques, which may be 15 appropriate to particular media sites that are going to be 16 characterized by DOE.

17 That we hope, combined with all the other 18 !nformation which both we and the Division of Waste 19 Management have gathered to this point, will allow a review 20 c f what DOE plans to do and an assessment.

21 DR. SHEWMON: This is what they plan to do duEing 22 the characterization?

23 MR. COSTANZI: During the characterization and 24 whether or not, indeed, they are going to be doing the kinds

() 25 of things which will resolve these kinds of uncertainties, ACE-FEDERAL REPORTERS, INC.

(}DAVbw 2 brine pockets.

3- I assume, sight unseen, that DOE will address 4 that and how they are going to investigate that under site 5 ' characterization. Clearly, if they do not, we will have 6 some ammunition to say, hey, look DOE, you've got to address 7 this issue. That is really our whole business, and what 8 we are going to -- that this chart is trying to illustrate 9 at this point. Eve ry thing is ready for site 10 characterization. That is what we have been doing. I think 11 we know enough about uhat sorts of things DOE wants to 12 directly-address when they characterize a site, that we

() 13 going to now shift --

14 DR. SHEWMON: One other thing.

15 These are unpaged, and you keep saying the next 16 one. The next one now has "First Repository" at the top of 17 it.

18 DR. LOCKE: Yes.

19 DR. SHEWMON: Good.

20 DR. CARTER: Let me ask a question related to-the 21 brine pockets. They have obviously encountered these at'the 22 . WIPP site. I guess my question would be, how large are 23 these things? I have a notion that these things are quite 24 small. A brine pocket might have two gallons of brine in

V 2 MR. COSTANZI: I do not know, offhand. It.is my 3 understanding that it is a very site-specific question. I 4 am aware that, for example, dome salts tend to have less of 5 a problem than embedded salts.

6 DR. MOELLER: Jack may have comments on that.

7 DR. PARRY: During my tenure with Battelle on the 8 salt project -- Nick's point is well-taken. It is very 9 site-specific, and embedded salts are much more subject to 10 that. They can be on occasion extensive, several thousand 11 gallons.

17 with the MRS't In short, are you factoring the two together, 18 is the name of the problem?

19 DR. LOCKE: We aren't, at-this time. We are 20 working on the assumption right now that there will be 21 several facilities.

22 MR. EBERSOLE: There is an awful lot of noise 4

23 going on in the newspapers about the necessity or 24 nonnecessity -- well, I think the thought is, from what I

)'DAVbw 2 one would have to at least look to some degree at.whether 3 that was-feasible or not.

4 MR. COSTANZI: One of the projects which we have 5 about finished, which was carried out at Sandia, it was on 6 the.preclosure risk, it was essentially to identify the 7 system structures. During the operational period although a 8 monitored retrieval storage type facility would be 9 considered, the method that was developed in doing that [

10 research would be applicable to that sort of operational 11 packaging type operations, were they to be carried on at the 12 respository site. They would not be applicable, however,.to

() 13 any further chemical processing. That would simply be 14 mechanical operations.

15 DR. MOELLER: Jack and then Dick.

8 I have a "what if" type question, which goes this 9 way.

10 Suppose one or more of the candidate sites goes 11 through a characterization process, you end up with ,what 12 looks to be, say, empirically, a real good site, good

_ () 13 geology, and you think, probably we wouldn't be able to find 14 a much better site in the country; however, in view of all 15 of the uncertainties which exist in modeling, particularly 16 in the far afield and the ability to measure things, you 17 have to tell DOE that, gee, you got some good stuff here, 18 but you fall very short of coming through in an ability to 19 demonstrate that you are really going to meet those 20 criteria.

21 What are you going to do about this? Are you 22 going to say, gosh, our tools aren't good enough to show 23 compliance, and therefore, we don't have a site?

24 DR. LOCKE: I am afraid you are asking the wrong

{}DAVbw 2 research at the present time? Let's say, a gut feeling of 3 whether this is going to happen or not. Are we 10 percent 4 there? Are we 90 percent there? How far have we got to go s 5 before the tools are going to be able to show that the site 6 is good? Not that it is bad, but the site is good.

7 MR. COSTANZI: I don't think that we will be in a 8- position where we will not be able to license a good site, 9 if the Department of Energy -- and I assume that it will --

10 demonstrates that the EPA stand'ards will be met or a 11 demonstration of compliance with the performance objectives 12 in Part 60. Our reviews center on all the event

() 13 demonstrations, and they will be by way of strengthening the 14 confidence in the degree of assurance that will be provided, 15 in issuing the licensem, that public health and safety will 16 be protected.

17 Our whole research program will contribute to and 18 will continue to aim at reducing the uncertainties to the 19 greatest extent we can. We will continue to do that up to 20 the time that the decision is made to either say, no, this i

21 is not a good site, or yes, close it off, the wastes are 22 disposed of.

6 DR. LOCKE: I think, in many ways, the program is 7 designed to demonstrate, when there are significant flaws, 8 there is always going to be questions as to the precision 9 and the accuracy and how much confidence you can have in a 10 given demonstration. It all boils down to whether you 11 believe the evidence is sufficient to give people enough 12 confidence to feel tnat they can make a disposal decision.

2. haven't-necessarily focused on.

3 Our program is so small that we are only focusing 4 on major issues. The process of reducing the-budget _has 5 made us stop working on basalt, which means that'we have 6 declared that as of right n6w we have sufficient information 7 on basalt to at least go through the site characterization 8 phase of the licensing process. We are not now trying to 9 develop new information on basalt applications.

10 That doesn't mean that we know everything about 11 basalt. If.you asked us tomorrow and gave us $2 million, we 12 ~ could identify work to be done in basalt.

17 MR. COSTANZI: I would like to point out that 18 when the Commission set up the licensing process for 19 licensing the geologic repository, almost in its entirety it

-20 was put into law by the Congress in the Nuclear Waste Policy i 21 Act.

i r 22 It envisioned an extremely cautious, step-by-step i

()DAVbur 2 indeed can build a repository that will work.

3 At that time if the Commission is convinced, they 4 will authorize construction and tell 90E to go build it..

5 After DOE has built it, then DOE comes back and 6 convinces the NRC that they built what they said they were 7 going to build and it will work.

8 And if the NRC is convinced of that they will say 9 go ahead and put in the waste. But by the way, while you 10 are putting in the waste we want you to continue to monitor 11 what is going on -- monitoring not in the sense of passively 12 looking for leaks but monitoring the environment in which

() 13 the wastes are being placed, to look at the interaction of 14 the emplaced wastes with that environment.

15 The whole physical standard.of the repository-16 right up until the time that the DOE can convince the 17 Commission that, hey, you know, we are not going to see 18 anything new. We are finished, we have loaded, things are 19 the way we said they are going to be. They are not 20 changing, let's close it.

21 The Commission says, yes, we agree, and it is i

22 done.

23 DR. SHEWMON: Let me ask a variant of that.

\, l 4 of steel you kind of hate to say how are you going'.to make J

.g 5 it, but the problem is still there. '

6 Do you feel that it is there after the license 7 has been granted, that they will do it with steel, that one. 3 8 should then get into the questions of, okay, what is your 9 testing and quality assurance program to show that this i

10 overpack is indeed what the modelers have assumed tit is?,

11 MR. COSTANZI: Are you asking when we should ask i

12 that question? '

() 13 DR. Si1EWMON: I am asking if it should be asked i 14 sort of in this quality assurance stage, which, as I 1

15 -understood what you said, was between we give you a license 16 to build it, now you come back next time and show us you j 17 built it the way you should build it.

18 MR. COSTANZI: No. As a matter of fact, part of 19 the site characterization plan specifically requests, as far 20 as DOE, to tell us what the waste package design 21 requirements are, tailored for the particular sites.

22 We acknowledge that,;the specific waste package .

23 plans may not be as well-formed as the site selection, but 1

24 we are looking at that early on. ;

MR. COSTANZI:

8 We are looking at that question 9 now.

10 DR. SHEWMON: You are having trouble. Part of it 11 is they say, well, we are not going to build it out of 12 steel, maybe we won't.

18 MR. COSTANZI: The DOE is required to give us at 19 least some information on specifications with the site 20 characterization. That is one of the things specifically 21 called out in the regulation.

22 We expect that at the time when they come in with 23 the construction authorization application, which is the 4

21 The decision to cut there as opposed to other 22 programs in high level waste research was, well, we had been i

17 I am just saying that given we have uncertainties 18 over here, over here, and over here, we kind of twist them 19 all down simultaneously. You can't cover all of them.

6300 09 09 114 DAVbur 1 MR. COSTANZI: You know, the reason we have this 2 coordination and.this ongoing coordination with the Division 3 of waste Management, staff to staff and management to 4 management, is simply because everyone in the Office of 5 Research. recognizes that the nature of research ar.d 6 researchers is to do research. We want to eliminate the 7 uncertainties. We all recognize th:4t is-an unattainable 8 goal, but we need to always keep in mind the perspective of-9 what is good enough for the agency, for the regulatory 10 agency to do its job.

11- Those interactions with the Division of' Waste 12 Management staff and management, as well as the discussions 13 of prelicensing with the Department of Energy, gives us that fs_)\

14 perspective.

15 So the judgment that we have done enough is not a 16 judgment made in isolation, not something that is arrived at 17 at a single point in time. It is something which we 18 approach, which we review continually, and in which all 1.

19 parties are involved.

4 20 I realize that is a fuzzy answer to your 21 question, but it is about the best answer I can give.

22 DR. LOCKE: Our program is so loan that someone 23 that needs an extremely great level of assurance would be 24 very nervous working in it.

5 Go ahead,-Marty.

6 DR. STEINDLER: Early on, Nick, you indicated 7 that you really were unable to identify priorities among the 8 few FINS that you had, the FINS that you did have, 9 considering that you have only got a total budget of 3 ,

10 million bucks.

11 You have obviously set some priorities. So 12 perhaps the selection among the-various proposals isn't q

J ,, 13 quite as difficult as you make it out. You clearly have set 14 all the basalt focus aside.

15 Is it also true that if somebody said your budget-16 has been cut to 200 K and you write one contract that you 17 absolutely would not be able to determine what that contract 18 should be?

19 MR. COSTANZI: I don't like to deal in 20 hypothetical situations, but I think I would make the 21 argument to my management if the budget were to be cut like 22 that, that it is not worth the effort. Put the 200 K in 23 another program.

24 DR. STEINDLER: But at 3 million, I am going to

6 what, a fifth of what it used to be when we looked the last 7 time, which'was not too many years ago.

8 I recognize the exigencies of budgets, but.I find 9 it incredible that you say that you cannot prioritize.-

10 MR. COSTANZI: The prioritization which I am 11 referring to is a quantification one, which gave weights to 12 various FINS against various attributes, and those

() 13 attributes are conventional attributes -- things like 14 contributions to the overall safety, reduction of 15 uncertainty, factors for whether this is a Congressionally 16 mandated activity.

17 I-can't recall, there were a number of such 18 factors, all given various weights.

19 DR. STEINDLER: I don't need to know the 20 factors. I am just making a cooment.

21 MR. COSTANZI: I am just saying that when we ,

22 applied these to the FINS that we have now they all came out 23 the same.

that was done in a subjective 3 way, looking at where we were.

4 1There is a numerical value that is associated 5 with the degrees and likelihood of success of the research..

6 Had that decision been made. during this prioritization 7 exercise, it would have-contributed to that, and I probably 8 would have rated those a little bit lower.

9 I can't say that the difference between the f

10 basalt work and the other work would have been 11 distinguishable. We certainly do have some range of values 12 in this quantitative scheme, and one could say, well, here

() 13 is where we draw the line at some time here and do it that 14 way.

15 My only argument is that we made that decision to 16 eliminate the basalt work. I gave you a consideration in 17 making that decision, but I can't really honestly say that 18 that was the best decision we could make. I can't tell you 19 whether it was a good decision; that is to say, I don't know 20 if it was a right decision.

21 But it is a decision we had to make, and we made 22 it. So that is pretty good.

.; DAVbw. 1 DR. LOCKE:' I am going to make a couple of' 2 remarks about techniques used to make decisions betweenLA

'3 and B, where A and B aren't necessarily quantifiably 4 discernable. When you use some kind of theory like that to 5 .make any kind of a political, social or economic decision, 6 fyou are fooling yourself, if you say that it properly orders 7 them._ You are-doing well, if you can demonstrate that 8 certain things fall out in certain modes.

9 This was found years ago in the reactor siting 10 area, when people tried to differentiate between reactor 11 sites by comparing so many things that it became foolish' to

-12 say that we have sites A, B, C, D and E, in that order.

() 13 Usually, you had three sites, which had benefits and 14- dis-benefits, and on the whole, they were equal. -When wo 15 came down to do the prioritization on the research problem, 16 we are doing the same thing. We are trying to take 17 qualitative statements, put numerical values on them, add 18 them up at the end and make some kind of a rank ordering of 19 these things. And it is' flat-out impossible, unless you can 20 get them approved, if there are certain characteristics 21 about certain research projects, which make them much more

.22 important than you get the projects, and there will be some 23 obvious way of discerning between them.

8 MR.~COSTANZI: I suppose we can. I am going to 9 have to check with Denny Ross about that. And I don't know 10 if he is ready to release that.

t 11 DR. PARRY: I think it is interesting to note, 12 though, that DOE used precisely the same process that you

() 13 did and came out with the basalt as their lead cite. I find 14 it also interesting that your grouping was horizontal, that 15 ' is, by geologic type, as opposed to being a. horizontal kind

'16 of cut, like all waste package work should be carried on or 17 all hydrologic work should be carried on.

I have a different question.

2 50 words or less, what is the status of it? Will we hear 3 about it again soon? Have you agreed to let a contract, or 4 what?

5 MR. COSTANZI: The FFRDC is being handled by the 6 Division of Waste Management. Joe Buxton is the fellow who 7 is really dealing with that. I can just briefly tell you 8 how research is involved in it. A notice of intent for the 9 FFRDC was published in the Federal Register. The connon 10 period on that, I believe, closed just recently, or is just 11 about to close. An RFP will be issued, I believe. That' is 12 the current plan. Research will have some work in that RFP,

16 MR. COSTANZI: More to the point, we feel that it 17 is going to be in our literal benefit to go with the FFRDC 18 contractor, to the greatest degree we can. One, it 19 eliminates the apparent conflict of interest problem.

20 Whether it is a real problem or an apparent one, it is still 21 one that goes away.

It was a copy of a letter that he had sent 5- to himself. l 6 I was here back on January 15th to_ talk a little-7 bit about the upcoming workshop. We actually did have it on 8 schedule. Some of these Vugraphs may look a little 9 familiar, but I just thought -- I changed the tenses on a 10 few of them. i 11 (Slide.)

12 We had this Workshop on Validation of the R( ) 13 Mathematical Models, and we had a subtitle, sort of a 14 caveat. We realized complete validation is pretty much an I t

15 unattainable goal in_a lot of these long-term performance 16 predictions on high level waste, so what we were trying to 17 get out of the workshop was a way to build confidence i 18 through coming up with synthesis of experiments and "

4 (Slide.)

5 How it is conducted depends on the final review 6 of what we have already had.

7 The January 15th meeting, I went into some 8 definitions that I will just go through briefly here.

9 One is on validation. What we are trying to get 10 on validation is assurance that the models are true, 11 adequate, at least representations of real physical 12 processes and systems that they claim to represent, and what

() 13 we met by a mathematical model is not a computer program or, 14 as some people call them, codes.

15 There's lot of gibberish about codo validation, 16 but these are models that may or may not be implemented by 17 the programs. So I put up this definition of mathematical 18 models. It is some sort of equation. I put down several 19 classes there of equations that subject the various 20 constraints that you need to have, in order to get solutions 21 out of the equations. The mathematical information you need 22 to get the solutions in order to make sense of these 23 equations.

24 DR. SHEWMON: You are not going to insist that n

( ,) 25 all of your equations had analytical solutions?

\' 2 DR. SHEWMON: Once you've got the mathematics, 3 _you are not against computers?

4 DR. RANDALL: Not at all. I just didn't want to 5 get hung up on things like miracle analyses and choice of 6 . language, software systems, and so on.

7 DR. CARTER: John, could I ask you a question?

8 What is the output of these things? Do you predict 9 concentrations?

10 DR. Rt.NDA LL : Yes. The main thing you want to 11 know about is concentrations, the quantities and rates of 12 radioactive material accessing the environment. So-

-13 concentration, of course, is very important. It also means O 14 other things like pressure distributions, groundwater flow 15 fields and temperature fields, as they all influence the 16 transport of the nuclides and tell a lot about the chemistry 17 of the transport medium, because they can slow down 18 nuclides, unless you design the repository cleverly.

19 DR. CARTER: You are predicting physical 20 parameters that, if there were things there, could be 21 measured, presumably, or you'd have no problem doing it.

22 My question is, how are you validating these 1 23 models, when I presume you have nothing to measure? What do ')

24 you mean by validation?

25 DR. RANDALL: Validation would be the exercise i

O ACE. FEDERAL REPORTERS, INC.

202-347 3700 Nationwide Covetage NA336-6646 l l

I 6300 10 08 126 DAVbw 1 of doing experiments and calculations, refining 2 calculations, refining models, until we get some measure of 3 agreement between the experiments and calculations.

4 Ideally, it would be exact, but that never happens. And it 5 is not going to be possible, in this sense, with high level 6 waste, becaur,e we are talking about such long time scales, 7 it looks like over several thousand years later.

8 DR. CARTER: But it is another plan.

9 DR. RANDALL: We do want to build up enough 10 confidence that we are extrapolating in the right 11 direction. We did have labs tests and analogs in some 12 fields. That is the sort of thing that we try to focus on.

7 w 13 DR. CARTER: My point is, it's not a validation, 14 in the sense of like reactor effluence, and so forth, that 15 you can actually predict what is going to happen and 16 transport movement in the environment. You can actually 17 '

measure those things and then validate them up .

18 DR. RANDALL: Reactor problems are shorter-term 19 problems that we can do tracer tests that are similar to 20 radionuclide migrations and some validations like that, but 21 they don't give the time factor.

22 DR. STEINDLER: I think the point that I think 23 Mel is getting at, which I would like to restate it, is in 24 that definition of validation, you don't show any notion

25 that this is, in fact, a short time interval aspect, whereas ACE. FEDERAL. REPORTl!RS, INC.

~~

6300 10 09 127 DAVbw 1 the application of your models is a much longer time.

2 DR. RANDALL: That is why the caveat subtitle is 3 put into the workshop. We know we are operating in a short 4 time to do the tests of validation. We are trying to 5 predict something that is going to happen over a very long 6 time. We are, in a sense, confidence building.

7 DR. STEINDLER: If you had added to the 8 validation definition, a phrase at the end that says 9 something to the extent, let's see, you have assurance that 10 mathematical models are adequate representation of the 11 preocesses and systems they represent, in time, then I think 12 I would have been a little more comfortable, because I can m 13 validate the bejeebers out of something.

14 DR. RANDALL: I could write something that says 15 space and time.

16 DR. STEINDLER: But I can validate the bejeebers 17 out of something in a short space of time, but you need one 18 more infinitely crucial aspect. That is the assurance that 19 is a long-term mechanism or description that is valid over a 20 long time. You don't seem to focus on that in those three 21 things you've got up there.

22 Is that my interpretation?

23 DR. RANDALL: You're talking about initial 24 conditions. That implies that you're talking about time 25 dependence. To me that is a very important problem of time ace-FEDl!RAl. REPORTERS, INC.

6 DR. STEINDLER: Let me rephrase my statement.

7 You can validate or you can generate a mathematical model 8 for anything, if you have all the data. But that is not 9 what you are interested in. You are not interested in 10 making mathematical models. You are, in fact, interested in 11 making mathematical models that are extrapolatable. If they 12 are not demonstrably extrapolatable, you don't care.

17 DR. STEINDLER: I understand that.

18 DR. CARTER: It may be a matter of nomenclature, 19 but I would be a lot more comfortable with model evaluation, 20 model comparison, whatever, other than validation.

21 DR. RANDALL: That's why we had the workshop to 22 decide how to do just those things.

16 Each day was self-contained. It began with some 17 introductory remarks about the issues of the topic-of that j 18 day, four or five presentations by specialists, and the j 19 issues we thought woro important for that dayh's 20 conference. That almost finished the morning.

21 The last session in the morning was for the 22 questions for the specialists.

6 In the thermally-disturbed zone, one suggestion 7 was that there were some calculations discussed about the 8 heat pipe effect in the unsaturated zone. That is to say, 9 there was vaporization naar the waste package and some 10 distance away from the waste package there was 11 condensation. It went through capillary offacts as far as 12 the recirculation. There's the potential for enhancement of O

14 We talked about a suggested in situ heater test 15 ' with some of the resources available to un. It's a do-16 able test to see if the predictions that were made about the 17 pipe effect would really happen. We need good 18 instrumentation data.

I know the research waste management offices 15 have had some arguments about it, but container is something 16 that contains something, or can contain something. That's 17 all I mean here. It could be the overpack, it could be the 18 cannister that's adjacant to the glass. What we're trying 19 to get at here is how those things corrode.

20 Metallic containers that are in contact with 21 groundwater in the thermal field degrade and open up 22 radionuclide release. One of the mechanisms that we've 23 defined in past research th<it h.is a real potential for 24 releasing radionuclides is pitting corrosion.

3 As those of you who were here at the time of our 4 lunch break realize, we did not cover two items this 5 morning. One of them was on the natural analogs, the other 6 was on the international cooperative effort on waste 7 research. We postponed the international cooperative effort 8 until a subsequent subcommittee meeting. And I want to put 9 on the record that I personally apologize to the NRC Staff 10 for doing that, because they have been down here about 11 three times, at least, to make that presentation, and we 12 seem never to be able to work it in, but I have been told

17 So Nick, I will turn my floor over to you.

18 MR. COSTANZI: Well, Dr. Gordon Richard will 19 actually be talking about our natural analog program.

20 Before he does that, I just want to explain a bit 21 about what we are looking for in natural analogs. As was u 22 mentioned this morning, one of the critical things used in 23 models to assess the performance of natural storage areas, 24 very short term observations are in extremely long times.

[ 25 We hope to get some idea of the validity of the models, as ACE FEDERAL REPORTERS, INC.

6300 13 02 154

( DAVbw; 1 well as that extrapolation process itself by looking at 2 natural analogs.

3 Natural analogs are things which occur in nature -

4 which have properties that are in some ways similar to 5 certain subsets of properties of geologic repositories.

6 What Dr. Richard will be speaking about is the 7 use of ore bodies, uranium ore bodies and' observe the 8 behaviors of radionclides from those ore bodies as analogs 9 to the long-term behavior of radioactive wastes in the 10 environment.

11 But there are other sorts of analogs which we are 12 looking at, or I should say, which we are considering t,-)s. _ 13 looking at, such as hydrothermal systems which would 14- involve, not radionuclides, per se, but other types of ores 15 being represented in hydrothermal systems heat and water, 16 which are, of course, two characteristics of high level 17 waste repositories.

18 So I would like now to turn it over to 19 Dr. Richard.

> 20 (Slide.)

21 DR. RICHARD: Here is a simple definition of a 22 natural analog similar to what Nick just said.

23 I would like to emphasize that the fundamental 24 reason for looking at natural analogs is the analysis of

() 25 understanding of processes that occur over long time ACE-FEDERAL REPORTERS, INC.

)

6300 13 03 155 1 periods. This is something we discussed this morning with

(}DAVbw 2 respect to model validation. It is the kind of role of 3 natural systems, because we looked at natural systems to 4 gain our understanding of long term behavior that we can 5 compare to a model prediction, so we can better valide our 6 testimonies and have better confidence in their 7 performance and the predictions we make using those models.

8 As you can see, we have several examples here.

9 One could be for a canister. It could be iron nails or 10 other archaeological sorts of things. Geothermal systems.

11 Uranium deposits, such as the one in the Northern 12 Territories.

() 13 DR. STEINDLER: May I ask a question? We had, in 14 that slide up there, an "and/or." Isn't the issue in the 15 case of the use of the data from natural analogs that they 16 have to be -- both the processes as well as the materials 17 have to be comparable to what the waste system looks like 18 before the data that you get out of looking at those natural 19 systems, makes any sense to you or can be used?

20 DR. RICHARD: I don't think it is necessary that 21 materials always be identical. It depends on exactly what 22 the objective of the experiment is. For example, if you 23 just want to understand some hydrologic model, I don't think i 24 one would necessarily have to go to the same kind of rock

-( ) 25 type to understand fracture pull. Fractures in granite may ACE-FEDERAL REPORTERS, INC.

202-347-3700 Nationwide Coverage 800-336-6646

6300 13 04 156 1 be similar to a fracture in tuff, for example. There might

. { '}DAVbw 2 be similarities, but one could go to different materials, 3 and-they might'still have physical similar properties.

4 DR. STEINDLER: My point is, don't you have to 5 identify that they will have similar properties? Isn't that 6 a necessary part of your analog use?

7 DR. RICHARD: Yes. This is generally why we do 8 try to go to the same material.

9 MR. COSTANZI: The similarity has to be in the 10 properties which control or determine the process clearly.

11 DR. STEINDLER: Yes.

12 DR. RICHARD: We have a very brief summary of 1 ) 13 some of the results of the Australian study. One thing 14 we've done is identified that thorium colloids could be.a 15 potential mechanism for thorium migration, and by analogy, ,

16 possible, also for the migration for plus 4 actinides, such 17 as plutoniums. That doesn't necessarily mean that.there is I

18 going to be large quantities of material to transport, but 19 of the quantities of material being transported, colloid 20 transport would be the dominant mechanism as appears to be 21 the case for thorium.

22 We are going to have to do further work to be 23 able to be sure how important this mechanism is, because 24 showing that there are colloids present isn't enough. One

3 With regard to developing procedures for 4 measuring radionuclide mobility in the field, there's been 5 work done in the laboratory and in Australian that has come 6 up with ways in which one can measure retardation in situ 7 for uranium series isotopes, but because of different 8 isotopes, if they are created by the same recoil process, 9 then one can start to understand the kinetics of the process 10 and use radon or radium as a benchmark to compare the 11 absorption of the other isotopes of the uranium decay 12 series.

O q_j 13 So that is one way one can actually measure a 14 real retardation factor, and also one can look at cores, and 15 again, the cores would give information on the extent of 16 retardation. So we've also developed laboratory procedures 17 that have looked ut the absorption process in a 18 process-oriented mode by doing selective leaching and 19 absorption, desorption experiments, where we have an 20 artificial isotope of, say, uranium or radium, and we also 21 have a natural isotope. So we put the sample in the 22 experiment, whether it be a batch type experiment -- one can 23 do a catch type experiment and observe the removal of the 24 natural uranium and the uptake of the artificial uranium.

() 25 One can also then later on do some leaching experiments to ACE-FEDERAL REPORTERS, INC.

9 DR. MOELLER: You did these experiments in 10 Australia, because --

, 11 DR. RICHARD: Because the sites in Australia have 12 a rock type. It's closer to the sorts of systems that we

() 13 are considering in this country. Namely, it is a j

14 crystalline type of work, also because the hydrology there 15 has been stable for a very long period of time and is fairly 1

16 well-characterized as compared to the hydrology in some 17 sites one might choose in the U.S.

18 So I think, hydrologically, one can, for example, 19 from preliminary analysis, it looks like Florida Farrell may 20 be an interesting place to study. But the hydrology of the 21 site is a very complex. We believe that the hydrology of 22 this site and on these sites, there actually is one that we 23 are planning to validate, and a number of sites we've looked 24 at. So we are doing model validation and trying to do one

8 MR. COSTANZI: I might also add that this project-1 9 is being funded, in part, by the Australian Atomic Energy 10 Commission, as well as by the NRC. We were amplifying our 11 -dollars in this case, as well.

12 (Slide.)

4 18 makes this sort of study much more feasible, because if one '

19 had to go into a virgin site, it would be uneconomical.

20 This is an example -- this is a diagram of one 21 particular site that we are planning to do studies at. This 22 was a virgin uranium ore body, in which groundwater coeps 23 through from a fault zone up through the ore body and f

24 remobilizes some of the uranium. The reason we are

2 happens in the case of Australia, to make the Australian ore 3 bodies, to make uranium 234 a little bit less mobile than 4 uranium 238. The thorium at 230 is very immobile, so it is 5 basically the least mobile constitutuent. Then you've got 6 more mobile constituents.

7 Using these profiles, one can use that profile to 8' compare to a model prediction of movement of those 9 isotopes.

10 DR. MOELLER: U-235, why is it not followed?

11 DR. RICHARD: We would follow U-235, if it were 12 different from U-238, but it shouldn't behave differently 13 from U-238, and it is in very little abundance. One would (f

14 assume that U-235 and U-238 would behave the same way, 15 because they are both primordial rather than U-234, which is 16 created by a recoil process.

17 DR. SHEWMON: I take it, U-234 comes from U-238, 18 with one alpha omission?

19 DR. RICHARD: Correct.

20 DR. MOELLER: That's not possible.

21 DR. MARK: Two betas.

\_/

2 enough to give this dif ference?

3 DR. RICHARD: Absolutely. There is a substantial 4 ambient recoil which can result in the uranium U-235 ending 5 up in a different lattice position. In sandstone ore 6 bodies, such as we have in this country, what it causes is 7 the uranium to end up in the water, so U-234 is more 8 mobile.

9 In Australia, shat it does is, it causes the 10 uranium to end up lost in a clay structure and, therefore, 11 less mobile. So, yes, there is a substantial energy of 12 recoil. I think a few hundred kev, if you want to analyze (j 13 it.

14 DR. MARK: I have the same question. To 15 understand this recoil, the alpha recoil, the 238 puts the 16 stuff in the clay or the water or whatever, and then it 17 moves later.

18 DR. RICHARD: It is true that it doesn't go 19 directly from uranium 238 to uranium 234. There is more to 20 it than that.

()DAVbw 2 SWIFT model, which is a very complicated model that we are L 3 using in the regulatory process to predict radionuclide 4 transport. It has been effectively taken apart to look at

. 5 'the transport component of the model.

17 What we are trying to understand is basically the 18 physics and chemistry of the real system. We are not at 19 this point trying to validate a huge model which, in fact, 20 at this stage is just not feasible. We are trying to go to 21 a much simpler model.

8 DR. RICHARD: That's, I think, a question we 9 should always ask in general with respect to repository 10 performance.

11 MR. COSTANZI: In this particular case, what was 12 done was to try to understand what was observed at the oro

() 13 bodf, and they made some deductions about the physics and 14 chemistry and what was going on. They compared what 15 predictions would be made using that simplified model with ,

16 running against the SWIFT program, and what they have shown, 17 indeed, for the particular kind of ore' body that'they are-18 looking at. They feel that they can run their analytic s

3 DR. RICHARD: Well, there are two valance states 4 generally for uranium, 6 or 4, and it is much more mobile in 5 the 6 state, which is precisely why we see uranium ore 6 bodies the way we do in a repository.

Predicting the 7 valance state of uranium is complicated by radiolysis.

10 DR. STEINDLER: . Bear with me for the far field or 11 bear with me for a thick container, for example, where 12 radiolysis really gets down to a fairly trivial issue, as

19 DR. RICHARD: That remains to be seen.

e 20 MR. COSTANZI: I think this. particular deposit 21 perhaps, like all analogs, is analogous to a piece'of the 22 repository. A particular piece of the repository this is 23 analogous to is the degraded or failed waste package 24 surrounded by an intact backfill, presumably some sort of

7 There ate certainly some things about this which 8 will not be analogous; namely, the high temperatures won't 9 be there. The corrosion products from the waste package 10 won't be there, although I to understand there is a 11 considerable amount of iron there.

14 of iron.

18 these kinds of things that we are looking now, looking from 19 wherever we can to find natural systems which mirror in some 20 fashion portions of the repository so that we can view that 21 and narrow down on that and go on to some other things as 22 well.

l 3 MS. DRAGONETTE: First, I thought I would review 4 'very quickly a little bit on what low level waste is and' i

5 what types of waste Part 61 applies to.

I 6 I wanted to emphasize that the definition of low 7~ level waste has developed over the years based on source, 8 not based on radioactive content or hazard. It has been 9 considered in law and-in practice everything, like high 10 level waste, spent fuel, mill tailings, and transuranic 11 wastes.

12 Under the current Policy Amendment Act it is I) 13 everything but high level wastes -- spent fuel, mill 14 tailings, and anything NRC classifies as low level wastes.

15 Low level waste is potentially generated by as 16 many as 20,000 licensees around the country, licensed by NRC

, 17 and the states. It has produced about half and half fuel 18 cycle and nonfuel cycle About half comes from the power 19 plants, about half from other sources -- hospitals, 20 university research.

21 It is generated in about 76,000 cubic meters, or

, 22 about 2.7 cubic feet a year. That has boon the level of 23 production since about '80. With the uncertainties and the 24 cost, there has been better management. So the levels

5 It is disposed of at three operating commercial 6 sites -- Barnwell, South Carolina; Beatty, Nevada; and 7 Richland, Washington. It is split about half and half 8 between Washington and South Carolina, and Beatty gets about i

9 1 percent.

10 MR. EBERSOLE: What is the range of incidence 11 that you have?

() 13 solutions less than 1, trash less than 1 -- you know, 14 half -- up to chunks of uranium, continued uranium 15 shielding. I 16 (Slide.)

17 I mentioned in the previous one.that there are 18 all sorts of physical-chemical points. This is just to give i 19 you an idea. It can be almost anything -- activated metals, 20 power plants, laborator, trash, animal carcasses, almost 21 anything in industry or research.

6 But this gives you an idea of the total volume 7 and total activity that is disposed of.

8 '84 was a typical year as far as we know. A 9 couple of things to notice about this:

10 Class A waste, the lowest class of waste, 11 constitutes 97 percent of the volume and 5 percent of the 12 activity.

() 13 Class C waste, only 1 percent of the volume and 14 78 percent of the activity.

15 Then if you do some arithmetic, you can see what 16 the average concentrations are.

3 Part 61. This is a general outline of the major 4 components of Part 61.

5 Part 61 is a health and safety regulation.

6 Imposed on top of it as you license an' operator site are 7 your environmental considerations under Part 51.

8 Part 61 itself is for the disposal site 9 ' operation. The amendments to Part 20 apply to the 10 generators or how the waste form and waste classification 11 provisions are imposed on the people who transfer wastes for 12 disposal at the sites.

() 13 But these are the basic elements: performance 14 objectives, technical requirements to help ensure you meet 15 them, financial assurances, licenses procedures, state and 16 tribal participation and exit participation in the review 17 and in the manifest.

\~/

2 entrapped participated?

3 MS. DRAGONETTE: Help licensed the site under 4 Part 61. This helps implement their existing rights as 5 landlord. It supplements their rights under the 6 environmental process in the local informal hearings, or 7 anything else.

8 DR. MOELLER: Could a tribe at a high level site?

9 MS. DRAGONETTE: There's no legal provision in 10 there for that. We do not provide for disposal on Indian 11 land, state or federal government land for disposal, so they 12 wouldn't be landlord.

() 13 As a landlord, the state can veto.- But none of 14 the bills deal with any explicit provisions.

15 DR. STEINDLER: What do you mean by "as a 16 landlord, the state can veto"?

17 MS. DRAGONETTE: At the existing site, except for 18 the Washington sites, where you have a sublease arrangement, 19 the land on which the disposal occurs is owned by the state, 20 before the waste went into the ground. And they continue to 21 own it and will own it indefinitely.

22 And it's a provision that was in effect since the

, 23 commercial disposal started in 1960, and we codified and 24 continued it in Part 61.

i

() 25 So, before a new site can begin operations, the ACE FEDERAL REPORTERS, INC.

202 347 3700 Nationwide Cmerage 800-3364M6

a 6300'15 02 .31 1 land has to be transferred from the states.

((}~DAV/bc 2 The state and the operator will have a lease and 3 they can impose a number of arrangements through that 4 lease. So not only do you have a health and safety-5 regulation and something that may come out of NEPA, you have 6 the state as landlord.

7 Then you have the state as their compact 8 commission representative. Low level involves states 9 wearing a number of hats. But the landlord is one very 10 strong one, 11 DR. STEINDLER: The veto is an implicit power 12 simply because'of the lease arrangement.

() 13 MS. DRAGONETTE: If they refuse to take title to 14 the land and you can't work out an arrangement with the 15 Bureau of Land Management or other federal agencies to take 16 it, you know, that could be a practical veto.

17 But you have to get government ownership.

18 DR. STEINDLER: Is it a requirement that the 19 state must own the land?

20 MS. DRAGONETTE: It can be state or federal.

21 DR. STEINDLER: So if the state vetos, they don't 22 really want to take title to it, the federal government 23 could nonetholoss hold title to that site.

24 MS. DRAGONETTE: Theoretically. But, with the

() 25 compact process in place, legally, all that is not that ACE. FEDERAL REPORTERS, INC.

202-347 3700 Nationwide Coverage Nn 336-fM6

6300 15 03 182 DAV/bc 1 clear. It's a requirement in the rules that there be an

'.^]%

2 agreement on the land ownership and the transfer for 3 long-term care.

4 And that is a way that they could drag their 5 feet.

6 (Slide.)

7 At the heart of Part 61, our performance 8 objectives, these are applicable to all land disposal of low 9 level waste. So are the administrative procedural parts, 10 the financial parts, and other parts of the rule.

11 Everything but the specific technical requirements so far 12 apply to any method of land disposal.

(} 13 But, because of the importance of the performance 14 objectives, because they are central to the rule as to any 15 alternative proposals for operations or classification, or 16 anything else that you might como up with at an individual 17 site, it's worth going back over those, I think, a little.

18 They cover four areas -- protection from releases t

19 of radioactivity, protection of inadvertent intruders, 20 protection of people doing operations and stability of the 21 site after closure.

22 MR. EBERSOLE: What are you doing about post-23 pluvial monitoring?

24 MS. DRAGONETTE: There's a specific requirement

() 25 in Part 61 that the custodial agency, the landowner for the ACE-FEDERAL REPORTERS, INC.

202-347 3700 Nationwide Co$crage 800 336-MA6

6300 15 04 183 1 hundred years of institutional control, develop an

( }DAV/bc 2 environmental monitoring program and surveillance program.

3 And one of the requirements before the license would be 4 transferred from the operator to the landowner is that the 5 environmental monitoring program be in good shape and ready 6 to be able to take routine samples during that time.

7 MR. EBERSOLE: What's the rationale about the 8 hundred years?

9 MS. DRAGONETTE: Because, well, they could 10 continue if they chose to. One hundred years limit is how 11 long you can rely on it in your analyses and rely on it to 12 take place.

() 13 There's no prohibition on continuing land 14 ownership or continuing to maintain fences, or continuing to 15 monitor if there's still a state agency around to do it.

16 MR. EBERSOLE: What's the potential of this stuff 17 versus the high level waste?

18 MS. DRAGONETTE: I'll get into that a little.more 19 with the classification charts and show you how all the 20 components fit together to work with the time lines that are 21 involved in the classification scheme.

22 So if I don't answer it later, remind me.

23 DR. MARK: What is this bit about protection of 24 individuals? Does that just entirely consist of some wire

() 25 fences and signs saying " Keep out", stuff like that?

ACE FEDERAL REPORTERS, INC, 202 347 3700 Nationwide Coverage 800 336-6M6

l 6300 15 05 184

/^3 DAV/bc 1 MS. DRAGONETTE: It's intrusion after the loss of V

2 institutional control. I'm going to talk about.each one of 3 those a little bit more.

4 (Slide.) '

5 But the pathway models that dealt with that said 6 that after a hundred years, the state no longer maintains 7 the fences. And it might look like a pasture. Then'you 8 might have a housing development on it. And people would 9 dig basements and grow crops in the soil that they dug up 10 from their basements.

11 It's that type of intruder, not knowing the site 12 is there.

() 13 DR. MARK: To ensure that he would not be harmed 14 then?

15 MS. DRAGONETTE: That his exposures would be in 16 acceptable ranges, yes. I'll deal with that in just a 17 little more.

18 The performance objective on the site boundary, 19 the numerical releases are calculated at the site boundary 20 and includes the ALARA concept, if it's reasonable to keep 21 it lower.

22 We did look, in developing Part 61, we did look 23 at a range of doses f rom one to 500. This comes out to look 24 like the 40 CPR 190 fuel cycle standard. That's because

( ) 25 it's sort of in the middle of the range, and because it was ACE. FEDERAL REPORTERS, INC.

202 347 3700 Nationwide Coverage 800 336 6646

6300 15 06 185 1 feasible and. practical when we went through the o%f'J'1 DAV/bc 2 comprehensive calculations of representative sites and 3 representative wastes.

4 It worked. So it was reasonable from an exposure 5 point of view, and it was reasonable because we believed it 6 could be met.

7 DR. STEINDLER: What's your time scale over which 8 those exposures have to be monitored?

9 MS. DRAGONETTE: At this one, forever.

10 DR. STEINDLER: So, in a sense, you're in the 11 same, general ballpark as the high level waste folks. They 12 say 10,000 years; you say forever. For me, that's the same

() 13 thing.

14 MS. DRAGONETTE: With some charts that come 15 later, I think, at the end of 500 years, things with low 16 level are pretty much to level off. You're down to a few.

17 Your initial concentrations of your long-lived materials and 18 your intruder exposures remain about constant.

19 DR. STEINDLER: The equivalent risk that the EPA 20 set for high level waste is drastically different than what 21 you have up there.

22 MS. DRAGONETTE: But EPA is looking at low level 23 waste separately.

24 DR. STEINDLER: I'm comparing apples and oranges,

() 25 I admit. But I'm comparing all nuclear waste.

q 6300 15 07 186 1 DR. MOELLER: How is it drastically different?

(}DAV/bc 2 DR. STEINDLER: The equivalent of one extra death 3 in a thousand years is significantly lower in terms of the 4 millirem whole body. j 5 MS. DRAGONETTE: This is annual per individual.

6 No individual should get more than one in 25 millirem.

7 DR. MOELLER: That's not necessarily true.

8- DR. STEINDLER: How far off am I?

9 DR. MOELLER: Let me comment. As you say, it 10 takes a little time to figure it out. But, if you use, say, 11 one times 10 to the minus 4 fatal cancers por rem and you 12 let a person have 25 millirem a year for their lifetime, 70 j ) 13 years, you find that the 25 millirem a year, on that 14 basis, is equivalent to the nuclear power plant safety 15 . goal.

16 It would produce in the population receiving 25 17 millirem a year, the cancer fatality rate would increase by 18 one-tenth of 1 percent.

, 19 DR. STEINDLER: Isn't that a lot higher than one?

20 DR. MOELLER: That is a lot higher than one death 21 in a thousand years. It depends upon the population 22 exposed. You know, there are so many things to consider.

23 This 25 millirem a year is the maximum individual. I mean, 24 no one can get fuller.

3 DR. CARTER: Aren't these numbers the same as in 4 40 CFR 191?.

5 DR. MOELLER: You're right.

6 MS. DRAGONETTE: But I tried to emphasize that 7 that was more or less coincidental, that we did look at a 8 range and legitimately examine the range during the 9 rulemaking process so we didn't just blindly adopt.

10 We looked at a range and we-looked at what would 11 work.

12 DR. STEINDLER: I don't think that's right.

15 DR.-PARRY: That's the public expasure during 16 operation.

17 MS. DRAGONETTE: Any release from the site during 18 operations and after over the long term.

19 DR. FOSTER: As a practical matter, does the 75 20 millirem to the thyroid over come into play?

21 MS. DRAGONETTE: I don't think so. I can't 22 really answer your question.

23 DR. MOELLER: In a " normal", quote / unquote, low 24 level site, certainly, the hospital waste would not have

() 25 I-129 in it. Do the resins?

3 DR. FOSTER: I would think that, even with 129, 4 .probably the whole body would come in.

5 DR. MOELLER:- Yes, I'm sure you're right.

6 MS. DRAGONETTE: Most of the calculations show we 7 were pretty well below it. And we might be depending on 8 site inventories.

9 (Slide.)

10 The second one was protection of the inadverdent 11 intruder. One thing to notice here is that from the 12 beginning, one of the fundamental concepts of Part 61 is

() 13 that you think through the whole disposal procons from 14 beginning to end as you make each of your decisions 15 concerning each component of the system and what you're 16 going to do at this site.

17 This objective reflects that -- the design, the 18 operation and closure of the site are to help assure that i

i 19 the inadvertent intruder is protected.

20 And it also includes the premise that he doesn't 21 intrude until after you lose institutional control.

22 DR. MOELLER: Carson, does that do it for you?

f 23 DR. MARK: You've got to guarantee that the junk 24 you bury won't hurt him after a hundred years, or something

() 25 like that. Or do you put it in a concrete box so that he j ACE FEDERAL REPORTERS, INC.

1 can' t get hurt inadvertently?

(}DAV/bc 2 MS. DRAGONETTE: The classification scheme, we'll 3 get into a little more. One of the premises here is that ,

4 under reasonable scenarios, an inadvertent intruder would 5 never get more than 500 millirem exposure. He's a i

6 hypothetical person; there may only'be a few of them, so we 7 used the higher number.

8 DR. MARK: But if I put it in a steel box, he 9 can' t do it inadvertently.

14 (Slide.) i 15 Protection during operations. This is strictly 16 just at a convenience to repeat that Part 20 applies, but 17 accept that Part 20 effluent release limits do not apply.

18 The only part of Part 20 that would apply would 19 be your direct gamma defense line.

20 (Slide.)

21 The last one was stability. That's one of the

{

22 important features of Part 61, was how critical stability of ,

23 the site was to your performance, the performance at the 24 site and the exposures that you would get. ,

() 25 Again, it's emphasizing from the beginning:  !

6300 15 11 190 DAV/bc 1 Consider stability in your thinking from the time 2 you site, the time you design it, how you use and operate 3 it, how you close it. Your goal is long-term stability that 4 helps minimize doses and helps minimize the burden on the 5 caretaking agency.

6 (Slide.)

7 Okay. To help implement those performance 8 objectives, the rule contains a number of technical 9 requirements in four major areas, which are essentially the 10 components of the system: site suitability, site design, 11 operation and closure, waste classification and 12 characteristics and institutional requirements.

f^')

v 13 (Slide.)

14 In an earlier slide, I talked about classes A, B 15 and C. This is a reminder that they are determined by the 16 radio isotopic concentrations only. It's not a total hazard 17 mixed waste thing; no matter what the nuclide content is, 18 class A waste is generally unstable and has to meet some 19 unstable waste form requirements that are designed to 20 protect the worker.

21 For example, no cardboard boxes so that needles 22 and syringes from the medical institutions stick them in the 23 hand if they are handling the box.

24 DR. MOELLER: Excuse me. You say it's segregated I) v 25 at the disposal site. You mean, they actually monitor it?

3 DR. MOELLER: It's all labeled.

l 4 MS. DRAGONETTE: It has to be labeled and marked l 1 I l 5 as class A and the generator has to determine that, market, 6 give you the paperwork, give you the content and maintain a  ;

7 quality control program for how he determined it. l i

8 But class A has the lowest concentrations. Class i 4 9 B waste is the next most hazardous and it must meet both the 10 minimum requirements and be physically stable. Stability in j

11 Part 61 is structural stability.

i 12 Class C waste must be minimum in stability

() 13 requirements and involve some sort of additional intruder 14 protection.

i 15 DR. STEINDLER: Is there anything in Part 61 that 16 defines the maximum total number of curies that can be 17 disposed of at any one site?

18 MS. DRAGONETTE: No. But the option is in 19 there. That, on a site-specific basis, you may need

{

20 inventory limits. And, in fact, one of the requirements is 4

21 that shippers identify the quantity of carbon as tritium and 22 iodine 129 and other nuclides that are likely to have site 23 inventory limits, so that you'll have the dats to track it.

24 But that would be a site-specific decision

() 25 because it's much more groundwater related than intruder.

7 Then after closure the operator remains onsite to 8 make sure that his closure measures worked, the crass is 9 established or whatever, and at that point all of your Class 10 A, B, C wastes are all recognizable and you would still be 11 able to tell the Class A trenches with drums and boxes and 12 whatever.

18 Okay, at the end of the 100 years of 19 institutional control the license would be terminated, and 20 beyond this point you can't rely on any active measures by a 21 government agency. You go into the passive mode.

7 DR. MOELLER: It has no liner?

8 MS. DRAGONETTE: It has no liner, that is 9 correct. This is just to show the continuity of the 10 disposal unit concept.

11 If it was an engineered facility, it would be.

9 If they dug down into your plant roots'and 10 things, you are still going to have a monolithic waste 11 package or waste form. But there would be some uptake 12 because the modelino did not assume that B and C -- that the

15 No single component of a system at a low level 16 site works' 100 percent. All of them contribute to meeting 17 the release limits, but there is not redundancy. You don' t 18 have 100 percent from several of the components the way you s 19 do at high level.

5 DR. PARRY: Kitty, more seriously, there is that 6 5-meter coverage.

7 MS. DRAGONETTE: 5 meter is for the Class C. So 8 the crops shouldn't intrude that deep.

9 DR. PARRY: Is it 5 meters to the top or to the 10 bottom?

11 MS. DRAGONETTE: To the top of the Class C. The 12 5 meters is from the grade surface to the top of the Class s

3 MS. DRAGON" 'E : No.

4 (Laughter.)

5 DR. STEINDLER: Let me ask another cuestion.

6 You indicate up there that the licensed custodial 7 care is about 100 years.

8 Does that imply that if I seek a license for a 9 low level disposal site and I go through all the licensing 10 processes, I can't get off the hook for 100 years?

11 MS. DRAGONETTE: Supposedly the 12 developer / operator gets off the hook after the post-closure r

(h,,) 13 observation period. Then the license would be transferred 14 for 100 years to the state or federal agency that owned the 15 land and was going to provide the long term surveillance and 16 monitoring.

17 DR. STEINDLER: That becomes a state function?

18 MS. DRAGONETTE: Right. We are into the 19 government phase. So the operator is off the hook after the 20 first 100 years.

21 Now, you do have passive controls. You do have 22 deeds. You have a requirement to put in granite marker 23 tombstones, but you can't guarantee it.

24 DR. FOSTER: For your Class A situation af ter 100

2 MS. DRAGONETTE: 500 millirem per year.

3 DR. MOELLER: That is the intruder.

4 MS. DRAGONETTE: The releases to groundwater, 5 air, things like that should meet the 25.

6 DR. FOSTER: The goal on that is really in terms 7' of concentration of the waste package when it is introduced 8 100 years earlier, right?

9 MS. DRAGONETTE: Yes. Concentration is limiting, 10 but for longlived materials your initial concentrations 11 would be limited. Shortlived materials can be, at least in 12 Class B and C, can be at about that theoretical limit that

() 13 you could shift.

14 DR. FOSTER: So it is a concentration combined 15 with a halflife consideration?

16 MS. DRAGONETTE: Yes.

17 (Slide.)

18 So through 300 years your R and C waste packages 19 are holding up. Beginning at 300 years, you continue with 20 another 500 years of passive control, the deed and whatever, 21 and you are in that period for 300 to 500 years. So your 4

22 Class B and C wastes are starting to disintegrate, and you 23 may start losing your intruder barrier.

24 Then after 500 years the calculations assume that

5 MS. DRAGONETTE: It is a conservative assumption 6 to deal with that intruder. Obviously, if he can still tell 7 it is waste and backs off and finds out what went on, 8 hopefully there would still be a land record.

9 Well, I thought maybe those would help put those 10 time lines and the assumptions behind the actual tables in 11 61.55,-Table 1 and Table 2. That was the collective set of 12 assumptions that we used to come up with those numbers.

gs

(_ 13 That was coupled with what the waste was expected to look 14 like through the year 2000, and it was looked at regional 15 sites around the country. So it could be applied across the 16 country.

17 I included the things NRC has jurisdiction over.

18 As I already mentioned, we might have site inventory 19 limits.

20 One thing worth noting is that we started out by 21 mentioning that low level waste was in everything but.

22 Well, the latest bill, the Policy Amendments Act says 23 ,everything but and anything that NRC classifies as low level r

[m\ DAV/bc 1 DR. POSTER: Kitty, my other question picks up on 2 the one I had before. Since, after 500 years, all waste is 3 consolidated and unrecognizable, this scheme says to me that 4 any Class C waste, if you waited 500 years, it would be the 5 same as the Class A waste is today.

6 MS. DRAGONETTE: That's a fair assumption.

7 DR. POSTER: Maybe, if you waited 400 years, 8 since the Class A waste has got 100 years to decay in the 9 first place.

10 DR. STEINDLER: Does that mean the iodine 11 concentrations for Classes A, B and C are all the same?

12 MS. DRAGONETTE: No. In fact, long-lived f"

13 materials are a factor of 10 different for A and C because

. 14 of the dilution that you would get, the Class C waste is 15 probably going to be in the bottom, and it would be mixed 16 with the five meters of cover above it or with the debris 17 from the intruder barrier.

5 DR. STEINDLER: Are we shifting the risk?

6 MS. DRAGONETTE: It's the way the intruder for.

7 groundwater and air releases, it's site inventory that 8 counts, generally. For the intruder, these scenarios, with 9 digging into the material, building the basement or growing 10 the crops, did take into account that you would have the 11 cover material, the amount of dirt, the diluting of the 12 waste before you did something.

() 13 If it's unrecognizable here, it's mixed in with 14 all the backfill and the cover material. That was the depth 15 and the dilution, as I understood it. They were two of the 16 major factors. The.re was a factor of 10 difference between 17 A and C and the transuranics and other long-lived 18 materials.

19 I can probably try to give you a better answer by 20 calculating it, the rate.

21 DR. CARTER: Let me ask you a couple of things.

7 MS. DRAGONETTE: They have volume left. They're 8 in the Rocky Mountain compacts. I can't speculate. The 9 political pressure to close it has gone; there's been a 10 change.

11 For example, I just came back from California, 12 talking to a group there. And they are using it as a

2 we have not modeled it and demonstrated it, you know, based 3 on site-specific. But, as we understand the concept, the 4 Corps of Engineers did look at it. It was one of the things 5 they looled at in looking at the site design and operations, 6 and whatever.

7 So I would say yes, there would be no reason why 8 not. And they included it in looking at.it.

9 HDR . STEINDLER: I don't think they have a five-

12 MS. DRAGONETTE: The most hazardous goes into 13 the concrete bunker type things. Then they backfill with

14 grout. And then stuff that would be more like our Class A 15 waste would go on top.

16 The mounted part is the lower activity waste. So 17 they're using their lower activity waste as an intruder 18 barrier to protect the high activity waste that goes in the 19 center in the grouted cells.

3 DR. MOELLER: The meeting will resume. We'll go 4 back now to Malcolm Knapp and have the second portion -- or 5 the third, depending on how you look at it -- portion of the 6 presentation on low level wastes. This will be on the Low 7 Level Radioactive Waste Policy Amendments Act of 1985.

8 Malcolm.

9 MR. KNAPP: Okay. What I'm going to do will be 10 to talk about the Amendments Act, discuss a little bit of 11 why the act was passed, and some of its impacts on both the 12 state and regional compacts that we foresee, and the impacts i f-(_)3 13 on the NRC.

la I'd like to begin by talking a little bit about 15 the 1980 low level act, to which these amendments were 16 created, because it was, I think, the pretty obvious failure 17 of that act to accomplish its objectives which resulted in 18 the amendments.-

t

_19 I think it's worth nothing that the 1980 act runs 20 two pages. The amendments are cloner to 200.

21 (Laughter.)

22 Now that's not quite as terrible as it sounds, I 23 but 30 some of the pages are really Title I, which addresses l 24 the work of NRC, DOE and states and compacts.

l 6300 17 10 217 1 seven regional compacts.

) DAV/bc 2 The 1980 Act did four principal things in my 3 opinion. It made clear that the states were responsible for 4 low level waste. It established a policy favoring regional 5 compacts as opposed to individual state disposal sites. It 6 set January 1st of this year, 1986, as the date as which a 7 sited state within a regional compact could exclude waste 8 from states outside that compact.

9 And it set Congress in a position to ratify these 10 compacts. That last item may be one of the main reasons 11 that the 1980 legislation was not as successful as could be 12 hoped; in the event that a compact were ratified and it y 13 could exclude waste from unsited states outside the compact, 14 then the effect is that a great many congressmen would be 15 from states which would no longer have a place to put low 16 level radioactive waste.

17 And for that reason, Congress was unable to I

18 ' ratify a compact; although a number of compacts were 19 proposed and brought to Congress for ratification, there 20 were other problems in getting the compacts together.

21 I think to ask what compacts were in existence or 22 seeking ratification and what states were in compacts. That 23 answer changed almost monthly.

24 So there was a lot of activity but not a great 25 deal of progress. And as January 1, 1986 began to appear, ACE-FEDERAL REPORTERS, INC.

202-347-3700 Nationwide Coverage 800-336-664^

, DAV/bc 1 in the future, last year, it began to be an item of concern 2 that the sited states that Kitty mentioned -- Washington, 3 Nevada and South Carolina -- might very well shut down their 4 sites if nothing adequate were done to assure new disposal 5 facilities.

6 So that brings us to the purpose of the act, to 7 solve that problem.

8 (slide.)

9 And very quickly, the act is intended to do two 10 things. It establishes -- let me switch the order on that.

11 It keeps the existing sites open so that the states which 12 are not sited will get a second chance to site I) ,

13 repositories. I spent enough time in the high level proqram 14 that I'm still calling them " repositories".

15 And it also establishes incentives and penalties 16 to er. hance or promote the establishment of new disposal 17 sites. I'm going to talk at some length about what some of 18 these incentives and penalties are, as well as some of the 19 milestones that states must meet to develop these new site 20 capacity.

21 (Slide.)

22 Now, very quickly, let me scan the features of 23 the act itself. The act is divided into 10 sections, of 24 which the first two are simply title and definitions of the I .) 25 remaining eight sections. I would note on the viewgraph and ACE-FEDERAL REPORTERS, INC.

6300 17 12 219 DAV/bc 1 in your handouts, we have asterisks by about six of them.

l 2 These are sections in which the NRC has a role of l

3 one kind or another that will probably be either significant 4 issues we'll need to resolve, or resources will be required 5 in significance to be able to cope with the 6 responsibilities.

7 Very quickly running through it, the amendments 8 were signed into law on January 15th of this year. What 9 they' done is, in Section 3, they have formalized something 10 Kitty mentioned earlier -- to make it clear that states are 11 responsible for class A, B and C wastes and that the federal 12 government is responsible for greater than class C waste.

(w j 13 section 4 principally reaffirms the federal 14 nolicy that they will want mutual compacts more than 15 individual state sites. They are interested in having a few 16 low level sites rather than a great many.

17 Section 5 is the most complext portion of the 18 amendments. It runs about half of the 30 some paces. It 19 does quite a few things. It sets volume caps on the amount 20 of waste which the current operating site will be required 21 to receive in a given year, and over the seven-year active 22 period of the act, it allocates the disposal capacity within 23 these volume accounts anciq RWR and PWR reactors, sited and 24 unsited states. And, by inference, from nonreactor

( ) 25 generated waste as well, it sets schedules that states must ACE FEDERAL REPORTERS, INC.

2 I_'ll talk about these a bit more later. But, 3 very briefly, by the 1st of July this year, states must 4 either ratify compact legislation or certify their intent 5 that they'll be developing a disposal site independently.

6 In about 20 months or so, January 1 of 1988, the 7 compacts must either identify a host state or provide a 8 siting plan which will accomplish this.

(^) DAVbw 1 By January 1, 1990, they must either submit _an

't) 2 application either to the NRC or the appropriate agreement 3 state authority or certify that they can manage low level 4 wastes by 1992. They must submit an application. The 5 penalties that are established, in the event that they don't i

6 meet these milestones are twofold. There are surcharges 7 which the sited states may charge generators of waste from 8 unsited states.

(

9 I will talk about what those surcharges are 10 later on. The first penalty allows these surcharges to be 11 doubled and cuadrupled as time passes an'd a state fails to 12 meet the milestones. An additional penalty is that after a r'N

() 13 period of six months or a year, depending on the nature of 14 the milestones, and this begins to become kind of 15 complicated, the sited states or compacts may deny access to 16 wastes from unsited states. And that brings us pretty 17 cleanly into Section 6 of the Act, which deals with 18 emergency access.

19 DR. MARK: zou said unsited states. May they not 20 deny access to all states? -

21 MR. KNAPP: It goes like this. Let's consider 22 South Carolina. They are sited. Consider -- let's take 23 state Y. State Y has not met the milestones. Let's say 24 they failed to provide an adequate siting plan in 1990.

4 DR. MARK: But that other state has either met 5 its milestones or has a site going.

6 MR. KNAPP: Exactly.

-7 DR. MARK: May not South Carolina then deny t 8 access to Illinois, because South Carolina has its own 9 arrangements, in effect? -

10 MR. KNAPP: I am not sure that they may deny them ,

11 access under the circumstances. I don't think they would 12 have that right at that point, i

15 MR. KNAPP: My reading of the amendments would 16 not give them that power, if Illinois was meeting its 3

17 milestones. Now there are a number of other things that 18 would figure into this. For example, there are volume 19 caps. For example, South Carolina is only required to take, 20 I believe, about 1.2 million cubic feet of waste annually. -

21 Certainly, that is one of the things that will not Le 22 exceeded by the state. So they will not be required to take 23 wastes from Illinois in excess of that, but my reading of 24 the Act is, at least I am unaware of a basis for denial of

(Q 2 DR. PARRY: May I? One thing that the 3 Southeastern Compact has done is, they have made a 4 regulation that generators within the Compact may not send 5 stuff outside the-Compact. So in that sense, if Illinois 6 was a member of the Compact or had their own, there might 7 well be a regulation in terms of the Compact. That would 8' mean that all the wastes would be kept there.

9 ,

MR.<KNAPP: That point is well-taken, and I 10 belie #vej that is an integral part of other Compact 11 legislation I have seen in other areas. Once they get 12 going, they are not going to want to let the thing out,

( ') 13 because they are going to want to make the money from it, 14 and of course, the motivating for generators begins to be 15 marginal, because these surcharges -- immediately, there are 16 surcharges in effect, immediately, of $2 a cubic foot. And 17 two years af ter that they will go to 20, ar.d two years after 18 that, they will go to 40. So there is a high motivation 19 once you have that capability.

20 MR. EBERSOLE: Do these funds essentially get 21 distributed to ratepayers? Are there no penalties in states 22 like California?

23 MR. KNAPP: I am sorry that I can't give you a 24 good explanation of exactly what will happen to these t /'T (j 25 surcharges./ ,

6300 18 04 224 1 Kitty, if you are a better student of this,

(-s) DAVbw 2 please feel free to correct me. I believe that 75 percent 3 of the surcharge goes to the state that accepts the waste.

4 let's say right now we are in a condition -- and again, I 5 will tell you frankly, I would rather not answer that 6 question. I've got a semi-good answer, and I might not give 7 you exactly the right one.

8 That is something that I would not like to get 9 into.

10 MR. EBERSOLE: Does it actually get back to the 11 ratepayers?

12 MR. KNAPP: Yes, I think it gets ' ack to the

() 13 ratepayers. The complexities of it, very simply, are some 14 of the money that goes into the surcharge will go to the 15 sited state. Some of the money that is involved in the 16 surcharges, 25 percent, in the event that there is a penalty 17 surcharge, goes into a escrow account which is administered, 18 I believe, by the Secretary of Energy, and some of that will 19 go to the state, but can be repaid to the generator, in the 20 event that they overcome a penalty, and as I say, it is 21 fairly complicated.

22 I will be happy to provide an explanation. In 23 any case, the emergency access provisions will provide some 24 fairly serious work for the NRC, because it is our job to l')

6300 18 05 225 DAVbw 1 and that is one that -- again, I'll speak a little bit more

.2 about each one of these jobs. I would just note that our 3 reading of the congressional intent is that emergency access 4 is expected to be a difficult thing to get. It is not 5 intended to be a loophole that states can use to avoid 6 meeting their obligations under the amendments.

7 DR. REMICK: Is that emergency access to federal 8 sites?

9 MR. KNAPP: No. Let me suggest that when ZI get 10 to the portion that deals with emergency access, I will talk 11 to that. If I haven't answered your question, please repeat 12 it.

13 Section 7 deals with DOE responsibilities, of f)

J 14 which there are, in my view, about three principal ones.

15 They are to provide certain technical assistance to states 16 developing sites, financial assistance, depending on what 17 funds Congress gives them for that purpose and a certain 18 amount of guidance on some things like site selection and 19 alternatives to shallow land burial. That leads into 20 Section 8 on all kinds of disposal methods, which is going 21 to be one of the larger efforts that I think NRC will be 22 accomplishing within this year. Within the 12 months of the 23 passage of the Act, we have to identify alternatives to 24 shallow land burial and provide guidance on them. Within

() 25 another year after that, we have to provide the information, ACE FEDERAL REPORTERS, INC.

6300 18 06 226 1 we have to identify the information that would be required

-()DAVbw 2 for sufficient other applications should someone want to go 3 with these.

4 Section 9 on Licensing Review, again, is a major 5 effort by the NRC. What we are to do there is within 12 6 months of passage of the act, we are going to have a lot of 7 things coming due next January.

8 We are to be able to review the low level 9 application within 15 months, and we are to be in a position 10 to do that next year.

11 And the last, Section 10, deals with wastes below 12 regulatory concern. In that area, we are to provide both 1

() 13 some standards and procedures for dealing with rates below 14 regulatory concern, and we are dealing with petitions on 15 these wastes and develop the technical capability, if we do 16 not already have it, to handle those petitions.

17 That is a very short term item, and it needs to 18 be done by mid-July. We've got six months to accomplish, t-19 DR. MOELLER: Now aren't you dependent upon the 20 EPA for some input on Item 10 or do you do that alone?

L) 2 MR. KNAPP: This figure simply highlights some of 3 the work which will be required by the states and compacts.

4 Those deltas which are marked in red identify actions which 5 the states or compacts must take over the next several 6 years, including either joining a compact or certifying the 7 intent to dispose of waste, identifying the coming up with a 8 siting plan, and then later on, in 1990, filing an 9 application. The additional arrows are the points.where 10 penalties will be imposed.

11 Just very briefly, of the surcharges, which are 12 in existence, now at $10 a cubic foot, if by July 1, when a

() 13 state is supposed to have ratified the compact legislation, 14 or certified their intent to develop a cite, if they have 15 not done so, then a surcharge will be doubled between now 16 and January 1, 1987.

17 If by 1987, by January 1st, they have not met 18 this deadline, then the sited states have the right to deny 19 access at that point.

20 So this concern about denial of access or 21 emergency access is not something -- potentially, it is 22 coming down on us in about eight months. That simply 23 depends on what sorts of actions individual states take in 24 the very near future.

() 25 That is a sort of a model for subsequent actions ACE-FEDERAL REPORTERS, INC.

l 6300 18 08~ 228 Jfv ) DAVbw 1 that may take place with each one of these steps. In 2 general, if a state misses a milestone for six months or a 3 year after that milestone is missed, the surcharges from the 4 sited states may be doubled or quadrupled, and then within a 5 year afterwards, access may be denied.

6 Until finally, we get to the point where, again, 7 Items 5 and 6, as you see, they overlay, so that in the l 8 event that a state has not filed an application or certified 9 that it will be able to manage its various taxes, the 10 application may be denied.

11 One of the things you probably should note about 12 this is that some of the staff are as little concerned about

(~)~

( 13 the timetable, saying it seems to start out rather smoothly, 14 and then all of a sudden seems to get very steep. And we 15 have some concerns that if a state were to simply meet the 16 timetable that has been established here, that is, in 17 particular, Item 3, if all they have really accomplished by .

18 the beginning of 1988 is to have a siting plan developed, 19 there is potential that by 1990, they are going to have 20 trouble having an application in to uc.

21 So one of the things are doing through state 22 programs and through outreach to the states is trying to 23 make them aware that just meeting the deadlines in the Act 24 might very well leave them in trouble later n in this

6300 18 09 229 DAVbw 1 MR. EBERSOLE: Tell me something. In this sort

(~')i 2 of rationale, is a state like Rhode Island treated just like 3 Arizona, for example?

4 MR. KNAPP: That's correct. But Rhode Island can 5 -- I probably should have had this as a Vuoraph -- Rhode 6 Island would be a member of the compact, and again, at this 7 point, I have to be careful. As of -- what was it, about a 8 month ago, 37 states, 39 states were members of ratified 9 compacts. I.believe, in the last few weeks, two of them 10 have announced their intent, but Rhode Island is not going 11 to have to develop their own site. In fact, that is not 12 what the amendments contemplate. They want regional-

-() 13 repositories, so that Rhode Island would be part of a 14 compact, probably in the New England region.

15 MR. EBERSOLE: The compacts have to be generated 16 by the states in cooperation with each other?

17 MR. KNAPP: That's right. It should be a 18 cooperative state venture, where the states ratify compact 19 legislation, and eventually this would be ratified by 20 Congress.

21 MR. EBERSOLE: Is there some kind of experimental 22 basis behind all of this? Does that come to some sort of 23 equivalency in the context of the investment to accomplish 24 this? Is there any equivalency principle in the context of

3 MR. EBERSOLE: Is there anything that looks at 4 the implications of the whole process?

5 MR. KNAPP: We've certainly looked at it from a 6 number of perspectives within the division. The problem is, 7 we are driven by a variety of things. In some cases, we are 8 driven by EPA standards. In some cases, we are driven by 9 Acts of Congress.

10 As I recall, and again, this is an area that is 11 outside by competence, but I believe in the high level

12 program, one of the things we considered when we wrote Part

/~N

( ,) 13 60 was the merit of, I believe, a value impact analysis, 4

14 which would have dealt with that problem, and for reasons

., 15 that I cannot recall right now, we did not perform such an 16 analysis. My recollection is, it may have been recognized 17 by both NRC and EPA that it was their responsibility, as 18 part of their standards-setting activity. But that is a 19 while back. I just don' t recall that well.

20 Certainly, that is sort of an analysis is 21 something that in my view would appropriately compare high 22 level-low level and, of course, uranium recovery, but that 23 is not something --

,6 involve EPA and probably would be pretty complicated. I am 7 not even sure we could accomplish much with it.

8 Kitty, would you like to comment on that.

9 MS. DRAGONETTE: My observation of EPA is that 10 they tend to approach each category of wastes separately and 11 look at technology and what could be accomplished and look 12 at it very practically, and then they set the standards.

() 13 As far as.the amendments act, Congress held the 14 hearings on the volume allocations and had industry 15 representatives, but other than something like that, I think 16 Congress was considering the low level problem in isolation 17 and leaving it up to the states to trade hazardous sites or 18 radioactive sites for prisoners, for something else. Sort 19 of behind the whole concept of the compact to negotiate.

20 Certainly, if one state is going to be the high 21 level waste, it seems that their fellow compact members 22 should take that into account.

And I think the real concern here 16 is, is DOE going to try to come up with something that might 17 be comparable to the enhanced near-surface disposal, or they 18 going to come up with something more like deep geologic 19 disposal? And if they come up with near-surface disposal, 20 we're probably going to have to pay some attention to the 21 definition of high level waste, such that we identify 22 cu t-of f , at which point everything which is more hazardous 23 or more active than a particular amount, we will go to a 24 deep geologic disposal site, and everything which is less

14 MR. KNAPP: Okay. One of the interesting things 15 that we have learned is that there is in fact an overlap 16 between low level and high level waste, not in a regulatory 17 sense necessarily.

18 There is high level waste in tanks or there is 19 material identified as high level waste in tanks which is of 20 a higher activity than other materials that are identified 21 as Class C wastes. That is one of the things that is a 22 little bit surprising.

5 DR. SHEWMON: Are some of the companies which are 6 going into toxic wastes volunteering to do this for a fee 7 for the states? Where do the states get the expertise?

8 MR. KNAPP The expertise on?

9 DR. SHEWMON: How to write this up and look after 10 it. Who is doing this for the states?

11 MR. KNAPP: Okay, I am not real clear. If you 12 are asking who might be developing low level sites, that is

(

A) 13 not entirely clear yet. The low level site in California is 14 being developed, I believe, by U.S. Ecology, or they have a 15 contract.

16 Other states, I am not sure if any of them have

18 MS. DRAGONETTE: Texas just set up a low level 19 waste authority, which is something like TVA. So in that 20 case you have the state sponsoring something on the 21 development side.

22 DR. SHEWMON: That is enough. Thank you.

v 2 MR. KNAPP: I don't intend to be prescriptive 3 about this stuff any more than absolutely necessary. Right 4 now we have about 21 staff working on low level in the Waste 5 Management Division.

6 MR. EBERSOLE: I can see why you wouldn't.

7 MR. KNAPP: What we are really hoping is that we 8 can really do several things, and I am sort of getting into 9 alternatives here.

10 But what we would like to do is work with the 11 states. There is some confusion on alternatives.

12 We have identified, as Kitty mentioned earlier, I ') 13 about half a dozen alternatives. The states want help on 14 alternatives. They want guidance, but they haven't been 15 particularly specific about what they are seekinq.

16 What we hope to do is work with them. Doing 17 that, we would like to narrow down the number of 18 alternatives to a few that are preferred. We have a couple 19 of options at that point. We may be able to provide some 20 guidance.

21 We would be pleased to see a couple of private 22 companies come forward with something that would be more or 23 less consistent as alternatives.

24 I am not saying anything about the commitment p

2 might look at.

3 We might even consider the merit of some sort of 4 requalification of some of these alternatives.

5 So hopefully by doing something like that we 6 could accomplish the goal. One of our goals would be to l 7 standardize, save money, and increase safety without being 8 prescriptive ourselves, and yet at the same time hear a lot 9 from the states.

10 That is an ideal goal.

( )) 1 As Kitty mentioned, with the 2 exception of what we will be required to do licensing this 3 above Class C facility, I am not sure if we ever license the 4 low level site.

5 And so the way we will make this thing work is to 6 provide things like format and content guides to states in 7 which we would anticipate in a number of cases they will 8 more or less adopt verbatim or very close to it, and then 9 through our agreement state program we would determine that 10 they are compatible.

11 That also applies to a number of other things, 12 like standard review plans and environmental review plans.

() 13 DR. FOSTER: Since you are going to be providing 14 pretty definitive guidance, might this not be considered a 15 significant federal action which required a NEPA statement?

16 If you decide that it isn't, is there any NEPA statements 17 required anywhere along the line unlees the states already 18 require that as a state action?

19 MS. DRAGONETTE: Can I answer that? There is a 20 categorical exclusion in Part 51 for guidance documents. I 21 looked that up for the regulatory concern guidance 22 documents, and they said, no, there wouldn't have to be an 23 environmental impact statement on guidance documents to be 24 issued.

7 MS. DRAGONETTE: If someone were going to apply 8 to us, well, it will be issued as if someone was going to 9 apply to us. Then the states-would adopt it also or use as 10 much of it as was appropriate in the circumstance, just as 11 they are adopting Part 61 if they are going to be 12 licensing.

() 13 They develop a model regulation to incorporate 14 their roles. If they didn't like it, they could expand on 15 it or delete, but it gives them something else to work i

16 with.

17 Whether the states have to do environmental 18 impact statements on the specific sites varies from state to 19 state. Many of the states do that.

20 California does. I was just out there, and they 21 do impact statements. New York does.

22 I don't know the state-by-state tally, but that 23 decision has been made earlier that the agrooment states are 24 not affected by NEPA. But many of them do something very

9 MS. DRAGONETTE: The provision in 10 CFR Part 51 10 is a categorical exclusion. I have forgotten the paragraph 11 cite, but it specifically says that when we are issuing 12 guidance documents we do not have to prepare environmental

5 What about this sort of thing with these-burial 6 sites, where states have interaction through waterways, and 7 so forth? Can they get in on the act, or do you argue that 8 the rivers, and so forth, there wouldn't be a transport 9 medium?

10 MR. KNAPP: The initial 1980 act, as I recall, 11 said that they were not going to get into transportation, 12 and I don't recall in the '85 act any mention of

4 We have a position on the street now on which we 5 have asked for comments on alternatives. Those comments 6 will be coming in in May, and beginning in June we expect to 7 have the first of a number of workshops, where we will be 8 discussing these alternatives and some of the concerns the 9 states have.

16 The developing of licensing review capability is 17 kind of an interesting requirement for Congress to put on 18 us. We have to have this capability developed and in place l 19 by next January.

20 The important part of this is to give the process 21 an application within 15 months. This is of some concern 22 because we don't expect to be getting anything in in 23 January, and why is it a good use of our resources to 24 develop this capability when we should be providing advice

2 Finally, we get to wastes below regulatory 3 concern.- At this point, I would like to return this to 4 Kitty, who will speak about where we are. This is one that 5 is of interest because we have to have our response done 6 within another few months.

7 Dr. Moeller, if it's in the interest because of 8 the press of time, if you'd like to move on to Executive 9 Session, we'll be happy to.

10 DR. MOELLER: If we can finish up in a few 11 minutes, let's go ahead with this. I would like 12 clarification on how this relates to EPA. And I gather the

() 13 answer is you are doing this independently.

14 MS. DRAGONETTE: Yes, there's nothing in the act 15 that requires us to use or wait for an EPA standard. I was 16 just meeting them Monday on their work. They were briefing 17 an internal committee on their regulatory concern work.

18 The way it will impact is, if, down the road, i

19 they do come out with a standard, they may have to go back 5

20 and reassess what we've done in the interim.

21 So that's how we're proceeding. They told us to 22 do it. There's no requirement to consult EPA, so we're 23 doing it.

24 We felt we could establish policies and

, [) 25 procedures. That's more or less a regulatory guide for ACE FEDERAL REPORTERS, INC.

()DAV/bc 2 and how we handle them rather than going through a generic 3 rulemaking.

4 With either alternative, there would be 5 subsequent rulemakings on individual waste streams. It's a 6 matter of what the scope of issues that you would consider 7 might be up for grabs in each one.

8 So, with the six months deadline, it's weighted 9 as one of the heaviest weighted decision factors. In fact, 10 that policy statement gets around for the second round of 11 comments. You know, so it's moving along and, hopefully, 12 will be to EDO by the middle of May.

() 13 One of the things we're doing in the document is 14 to make it clear that the burden is on the person 15 petitioning for the rulemaking. If he wants his rulemaking '

16 petition handled expeditiously, he's going to have to do the 17 work.

18 So that's a key premise in there. And another 19 important consideration is that what we're talking about is 20 deciding which waste streams don't necessarily have to go to i

21 a licensed low level waste site, that would be appropriate 22 to go to sanitary landfill or hazardous waste incinerator 23 and whatever that appropriate disposal method was.

()DAV/bc 0 requirements on-surveying and compliance and making sure 3 that he indeed transferred it to the right facility.

4 There would not be any regulatory control over 5 the preceding facilities. The sanitary landfill would not 6 be licensed. So that's how we're interpreting it.

7 The disposal itself would not have to be 8 regulated.

9 DR. .STEINDLER: Are 'you saying in that strategy

10 statement that you're going to avoid the issue of generic 11 rulemaking?

12 MS. DRAGONETTE: Delay it at least, for a number

17 We think, for one thing, it would duplicate what 18 they're doing and it would involve several years -- if I 19 ever --.you know, the whole de minimis issue.

20 DR. STEINDLER Okay. If I were not happy with 21 what you folks are doing in that area, the only way I could 22 block you is to tie you up in court.

3 the deep end is to continue to drive you inte,the court and 4 say you're illegitimate or you can' t do this because EPA 5 hasn' t given you the guidelines? Or make up some sort of a 6 case? Is that what you're doing?

7 MS. DRAGONETTE: That wasn't what we were trying 8 to do. What we were tring to do was facilitate individual 9 rulemakings on waste streams. There will still be a formal 10 rulemaking process that has to follow the administrative procedures with proposed rules, comments and final. i 11 i 12 Those petitions, those rulemakings would, we

() 13 think, we could do them on an expedited basis and do them 14 quickly in matters of months rather than years. If you 15 follow the guidance, submit the information that's in this 16 policy statement we're developing, it would not eliminate 17 the public or state involvement in each individual 18 rulemaking in response to a petition.

19 This is guidance for how to submit a petition.

20 The legal action comes in our action in response to the 21 petition.

22 Does that help? -

23 DR. STEINDLER: Not a whole lot.

24 HS. DRAGONETTE: We're asking for comments on the 4

i worded so that if we got serious significant comments, we 3 could revise it.

4 In six months, I really didn't have time to go 5 over the proposed policy statement comments in final. So 6 one of the things that can happen is you can comment on the 7 policy statement itself, before any petition is filed under 8 it.

9 secondly, you can participate in the rulemaking 10 for each individual petition that is filed, 11 DR. STEINDLER: Do you mean rulemaking for each 12 individual petition? Do you mean licensing action?

_() 13 MS. DRAGONETTE: No. The last item on there, 14 licensee proposals will continue under 20.302. If there's 15 one sandblasting sand, that should still come in as an 16 individual licensing action as 20.302.

17 This policy statement is dealing with more 18 generic waste streams where a category of licensees would be 19 able to use it. The waste oil petition that is pending is 20 an example. It's for a thousand gallons of waste oil at 21 each nuclear plant in the country.

22 So the petition fartrulemaking, the only time we

3 DR. REMICK: What is that proposed individual 4 rulemaking procedure? Are you going to publish it, receive 5 comments? Is there an opportunity for hearing?

6 MS. DRAGONETTE: If somebody asks for it or if 7 the Commission thought we should, the Commission can always 8 voluntarily hold information or formal hearings, or 9 whatever, on a rulemaking. It's not very common to hold 10 hearings on rulemakings.

11 DR. STEINDLER: Is it true, if you had a 12 rulemaking that was not contested and was put into effect,

( w) 13 say, on ordinary contaminated oil, is it clear that next 14 time somebody came to you with a thousand gallons of 15 contaminated solvent, that everybody would understand that 16 that may be a separate issue?

17 Or is this going to fall under, well, it looks a 18 lot like oil. We've already gone through this thing, so 19 it's going to go?

20 MS. DRAGONETTE: I'm trying to make that clear in 21 the policy statement that we would expect these petitions 22 l that we can handle expeditiously to very clearly define the 23 ways, and the rulemaking would be specific to the way it's 24 formed. With the biomedical room, it's for liquid fx

4 DR. MOELLER: Back on your question, Marty, when 5 you were saying if you were someone who wanted to stop the 6 process, the high level waste standards were written without 7 EPA guidance. They simply, you remember, talked to EPA. In 8 fact, they had to go back and backfit the standards of the 9 regulation.

10 DR. STEINDLER: We all recognize that the high 11 level of limitation was certainly not so quick as to avoid, 12 you know, an interface between EPA.

() 13 Here, the thought is that, since I haven't heard 14 any words from EPA on how fast it can move, I think the 15 thought is to act in the sense of disposing of something 16 before the EPA gets around to making up its mind.

17 At that stage of the game, the concern I had was 18 that the public hasn' t had a chance to look at the rationale 19 in the broad sense. But if you continue to hold a whole 20 series of rulemakings that are narrowly constructed, then I 21 think you can probably protect the interests of the public 22 reasonably well.

23 If it gets to be a grandfather or a broad issue, 24 the guy says it's oil, it looks just like a solvent, it

5 MS. DRAGONETTE: I agree with you. Our whole 6 emphasis is to hone in on very specific, narrow streams, 7 specify those and the rules that would respond to those 8 petitions.

9 That still leaves one of the difficult parts of 10 it, of how to deal with multiple streams. Now we're trying 11 to address that through keeping the exposures from any 12 individual stream very low.

/~N 13 DR. MOELLER: Okay. Go ahead. But I think we'd 14 better wrap it up.- As a final question, you have starred on 15 your third slide, you know, the policy act amendments and 16 the sections where you have made your major responsibilities 17 within the NRC.

18 What could we do? What can the subcommittee or 19 the committee do to be of assistance?

20 MR. KNAPP: I can think of a couple of things.

21 At some point fairly soon, I would think possibly 22 at the next meeting that you have or the one after that, 23 we're going to have feedback from the public on alternatives 24 to shallow land burial.

) 25 At some point, we'll be responding to those and I ACE-FEDERAL REPORTERS, INC.

202 347-3700 Nationwide Coverage 800-336-6646

6300 20 09 255

(~') DAV/bc 1 would very much like to involve the ACRS. I'd like to get (J

2 your comments on what you think of those alternatives.

3 That is the first item that comes to mind. There 4 is a technical capability that we are developing dealing 5 with below regulatory concern which consists of -- in fact, 6 it's pretty well-developed. It's a computer code which 7 models the impact of waste which might be termed below 8 regulatory concern.

9 You may or may not be interested in hearing about 10 the concepts behind that model. That's a model which has 11 been accepted and which has been working in industry and 12 might be something you could look at.

() 13 Those are the first two possibilities that come 14 to mind.

15 DR. MOELLER: We would like to hear about that 16 because this below regulatory concern ties into the de 17 minimis dose rate, say, and, you know, in 10 CPR 20, it had.

18 the proposal that one millirem a year would not be used in 19 the calculation of collective doses. From that point below 20 would not be used in the summing up of the collective 21 population.

22 Well, in the committee, when we responded and 23 commented on 10 CFR Part 20, or when the subcommittee did, 24 we said, in general, that probably was all right. But we

/N 25 also said we still needed to know the distribution of the

()

ACE FEDERAL REPORTERS, INC.

202-347-3700 Nationwide Coverage 800-336-6 4 6

6300 20 10 256 1 numbers of people out there in the public within each dose

()DAV/bc 2 range.

3 And at the time the subcommittee met, we were 4 told, oh, the British do this. But, then, when we dug into 5 what the British do, we found that they said you could throw 6 away up to 100 personrem uncollected dose, but don't-throw 7 it away if it's more than that.

8 So I'm delighted to hear, if I'm reading into 9 what you're telling me to determine the concentration that's 10 below regulatory concern, you do not just pick a number.

11 You take that particular waste and whatever is in it and you 12 plug it into some sort of a computer code, which models some l')

( 13 scenario.

14 And if it comes out at the end of that scenario, l

15 then it may be below regulatory concern. If that's what I'm 16 hearing, I cheer for you.

17 MR. KNAPP: That is exactly what you're hearing.

18 MS. DRAGONETTE: And it does pathway and 19 exposures from point of generation. The truck driver, the 20 sanitary landfill operator.

21 DR. MOELLER: I would love to see that, and for 22 us to review that.

23 Mel?

24 DR. CARTER: That sounds good to me. I'd be very

() 25 interested in that.

202-347-3700 Nationwide Coverage 800-336 6646

6300 20 11 257

(~) DAV/bc 1 One question I had, it was my impression that v

2 these amendments now gave the NRC the authority to designate 3 other materials as low level waste.

4 Now, you've not addressed that specifically. But 5 the question is:

6 What do you intend to do with NARM?

I 7 MS. DRAGONETTE: You're saying that that seems to 8 give us legal authority over NARM? That's creative.

9 (Laughter.)

10 DR. CARTER: It sounds like you've got it and 11 didn't even know it.

12 MS. DRAGONETTE: That would solve one of the fm 13 problems.

()

14 DR. CARTER: Yes, it would. It would solve a 15 problem that the states have had for many, many years.

16 MS. DRAGONETTE: As far as I know, that has not 17 occurred to any of the 20' policy people that have looked at.

18 that.

19 DR. CARTER: Let the record give me credit.

20 (Laughter.)

21 MR. KNAPP: We'll give that very serious 22 consideration.

23 DR. CARTER: I'm very serious.

24 MR. KNAPP: The two concerns, as I think you

() 25 probably know, that we brought to the attention of Congress, ACE-FEDERAL REPORTERS, INC.

202 347-3700 Nationwide Coverage 804336 4 46

_ ~ , ,

6300 20 12 258

( ,) DAV/bc 1 which they did not address in these scenarios, one is are ann 2 and the other is mixed waste.

3 You may or may not be aware that we are jumping 4 through lots of hoops right now and we are starting our 5 third and fourth hearing of four hearings on mixed waste.

6 DR. CARTER: This is the CERCLA revision? That's 7 the fourth?

8 MR. KNAPP: The concern we're involved in is what 9 about wastes which are chemically toxic, hazardous wastes, 10 as well as radioactive. Generally, low level radioactive 11 wastes.

12 Therefore, they fall-under both RCRA and AEA and

) 13 the regulations administering these acts are not entirely 14 consistent, where all of a sudden, it becomes pretty brisk 15 to try to weed your way through that.

16 So what we're looking.for, what the Congress is 17 seeking to do is to come up with a method of simplifying 18 this situation and giving appropriate responsibility to an 19 appropriate agency.

20 DR. STEINDLER: Could we define what "NARM" is?

21 DR. MOELLER: The question is what is NARM. It's 22 Natural and Accelerator-Produced Radioactive Materials which 23 are not legally, generally covered.

24 MR. EBERSOLE: You pitched de minimis then as the

() 25 ultimate biological potential through some scenario or ACE-FEDERAL REPORTERS, INC.

202-347-3700 Nationwide Coverage 800-336-6646

6300 20 13 259 1 process. And I want to endorse that as the only way.

()DAV/bc 2 DR. MOELLER: I do. And this is a very poor 3 analogy, but I find it's the best I can come up with:

4 To just say one millirem a year is okay without 5 considering for how many years that's going to last, or how 6 many people are involved, or over what space, as I say, we 7 use the analogy that someone came up with which was helpful 8 to me was that:

9 It might be all right to permit the people in 10 Washington, D. C., all the people here to have one millirem 11 a year if through that you could provide electricity to the 12 entire United States.

() 13 But it would not be permissible to give one 14 millirem a year to everybody in the United States to provide 15 electricity to the District of Columbia.

16 So there's more to it. I think they're exactly 17 on the right track.

18 MR. EBERSOLE: I do, too. I've got a gnawing 19 feeling though that the low level waste in the biological 20 potential text may be more potent.

21 DR. MOELLER: Certainly.

22 MR. EBERSOLE: Because of the more casual 23 treatment that it gets.

24 DR. MOELLER: I think, with that then, let me

I 6300 20 14 260 1 stimulating discussion. And what is the timetable now on

- (v) - DAV/bc 2 these two questions you asked? When will the public 3 comments come in, and so forth.

4 MR. KNAPP: The public comments on alternatives 5 will be coming in in mid-May. We will be having -- we have 6 a reasonably strong -- we will have an analysis. We will 7 have a meeting with a number of the states in late June. So 8 that sometime around that time, perhaps after the state 9 meeting, again, depending on when your next scheduled 10 meeting is, we can talk about our analysis as a result of 11 the state meeting.

12 With respect to no regulatory concern, we have tc

() 13 have something together in about three months. So I would 14 assume a mid-summer meeting would probably be required.

15 DR. MOELLER: Let me thank you again. And with 4

16 that, I will declare that today's formal subcommittee 17 meeting is recessed and we'll resume at 8:30 in the ,

18 mo.ning.
