1                        PROCEEDINGS 2              MR. MOELLER:    The meeting will now come to order.
3  This is the first day of the ninth meeting of the Advisory 4' Committee on Nuclear Waste.        I am Dave Moeller, Chairman of 5  the ACNW. Dr. Martin Sheind19r, one of the other members of 6  the ACNW, is also present.      Dr. Clifford Smith will not be                                                      3
,                7  with us for this meeting.      We have a team of consultants 8  here for the meeting consisting if Eugene Voiland, William 9  Hinze, Judith Moody, and bonald Orth.
10              This is the first day of a three day meeting.                                                        And 11  during today's portion of the meeting, we will hear a 12  presentation on the technical position on post-closure seals 13  in an unsaturated. medium.      That will occupy the morning.
  /            14  And then this afternoon we will hear on the preliminary b''
15  fundings of the waste confidence review group.                                  And that 16  will be followed by an'open executive session in which we 17  will try to formulate committee positions on these two items 18  and consider writing letters on each of these subjects.
19              This meeting is being conducted in accordance with 20  the government's Sunshine Act and the Federal Advisory 21  Committee Act. Owen Merrill seated on my right is the 22  designated federal official for the initial portions of this 23  meeting.
24              The rules for participation in today's meeting 25  have been announced as part of the notice of this meeting Heritage    Reporting Corporation (202) 628-4888

And it is requested that each speaker go to a 7                            microphone and please identify himself or herself so that                                                        j 8                            the Reporter can take down that information.                                      And also speak 9                            with sufficient clarity and volume so that everyone here as 10                            well as the Reporter can hear what is being said.
11                                      Before I call on the first group to make their 12                            presentation, I have several announcements that Mr. Fraley 13                            has discussed with me, and we jointly believe that they 14                            would be of interest to the committee and to those who are
                  }
15                            present today.
16                                      First of all', the NRC has established an Office of 17                            Inspector General effective April 17, 1989.                                      Martin G.
18                            Mulsch, former Deputy General Counsel for Licensing and 19                            Regulation, is the Acting Inspector General.                                      The functions 20                            of the former Office of Inspector and Audit have been 21                            transferred, and the Office of Inspector and Audit has been 22                            abolished. Those duties have been transferred to the 23                            Inspector General.
24                                      Secondly, the NRC has approved one stop licensing 25                            for standardized nuclear power plants.                              This will lead

7      Mr. Watkins has proposed that Mr. Stello be appointed as 8      DOE's Assistant Sec4Vtary for Defense Programs.              Before this 9      will take effect, Mr. Steilo would have to be nominated by 10            President Bush and approved by th3 Congress.              But it could 11            be of significance to our operations.
12                                Dr. Herbert Couts, whom many of you know and who 13            is a former member of the ACRS for example, had a heart 14              attack roughly a week ago last Th'2rsday, and he was taken to 15            George Washington University Houpital.              He apparently is 16            recovering nicely and he is supposed to be released today.
17            And I know that all of us vould be pleased to hear that 16            news.
19                                Lastly, the second building for the White Flint 20              site has been approved with several conditions by the 21            Montgomery County Planning Board.              And the building permit l
22            is expected to be issued within the next ninety days.              And 23            when that building is completed, of Laurse we would be moved 24              out there to hold our meetings anc he in closer physical 25            location with the rest of the NRC which would be a nice step

2                                                MR. STEINDLER:    I hope that somebody is looking at                      1 3                                    the QA problem on the drinking water fountain.
                                                                                                                ~
4                                                MR. MOELLER:    All right.        For those who do not 5                                    know, the drinking founhains in the current building had a 6                                  problem of lead. And then a,s Marty and I noted, in order to 7                                    correct the lead problem if you believe the NRC weekly I
8                                    information report, they added radium sulphate to the water, 9                                    and it was probably something like barium sulphate, but it 10                                    said radium sulphate.      And no wonder the NRC shines.
11                                                This morning then we are going to be covering                              j 12                                    first of all to repeat the post-closure seals.                    We are 13                                    talking about the technical position for such seals in an
{} 14                                    unsaturated medium.        I informally asked the staff if as th*-
15                                    beginning of this discussion and particularly for me if they 16                                    would really give me a'better physical feeling of where 17                                    these seals go, and what they look like, and how many of 18                                    them there are and so forth.        So they have said tlat they 19                                    are going to do that, and I note tnat they have brought with 20                                    them a model which may be very helpful to us.
21                                                So there will be then first of all a description 22                                    and a discussion of the draft technical position, and that 23                                    will be handled by Dr. Dinesh Gupta.                    And then that will be 24                                    followed by a discussion by John Buckley, who will tell us 25                                    how the staff resolved the public comments that were

              '3-              MR. GUPTA:        Good morning. My name is Dinesh 4  Gupta, and I am with the Division of High Level Waste 5  Management at NMMS.          Th1s morning I am going to present to 6  you the draft technical position on post-closure seals in an 7  unsaturated medium.
8                  (Slides shown.)
9              May I have the next slide, please.                            Just to give 10  yu. some background, I will briefly go over with you DOE's 11  proposed conceptual design of the repository, and then tell 12  you something about DOE's current seal decign concepts.
13  After that, I will go over the regulatory requirements, 14  the 1D CFR 60 requirements, that pertain to the seal design, j            15  the se<i testing, and the performance requirements for seals 1_
16  and the performance confirmation testing requirements for 17  the seals.
18                I will briefly describe to you why we thought that 19  a seal technical provision is needed, and then go over the 20  NRC's staff technical position on sealing issues.                                            i 21              MS. MOODY:        Are your first two comments 22  specifically to Yucca Mountain or are you speaking of them i

3                                In September of last year, we sent the technical 4                      provision for public comment, and we have received a number 5                      of comments on the technical provision.                    John Buckley is 6                      going to go over the proposed resolution of those comments 7                      with you later on.
8                                I would like to walk through that repository model 9                      that I have over there just to give you some idea as what 10                              the final repository will look like and how the seals would 11                              be in place in that. I do not know if you can vil see it.
12                                        The final repository would have the surface 13                              facilities and the underground facilities.                          The surface
{}                          14                              facilities is where the waste would arrive, and this would 15                              be handled for taking it down.      The waste would be taken 16                              down from the surface.'
17                                        MR. MOELLER:    What is the scale?
18                                        MR. GUPTA:    The scale on this, if you see the 19                              underground facility here, it would be about a mile and a 20                                half wide by two miles long.      That might give you some idea.
21                                The distance width ? rom the surface facilities to the start 22                                of the actual underground facility is about a mile.                                              That 23                                might give you some idea about the scale of this thing.
24                                          After the waste is ready for taking down, it will 25                                be taken down through a ramp which would be at an incline Heritage    Reporting                  Corporation (202) 628-4888 I

[J'T                1  going from the surface to the underground facility about a 2  thousand feet below the ground surface at this location.
3                In the final repository, there will be altogether 4  six openings from the surface to the underground.        One of 5  them,  as I just mention'd,e woyld be this waste handling 6  ramp. There would be another ramp that would be used.          The 7  ramp is here.      That would be used for carrying the excavated 8  rock out of the underground facility.        When the rock would    ,
9  be excavated, it would be carried to the end of the ramp.
10          This would be another half a mile or mile long ramp.
11                      In addition to these two ramps, there will be four 12          shafts. The two shafts, as you have heard about, during the 13          exploratory shaft facility discussion known as exploration 14          shaft one and two.      In the final repository, they will be 15          used as ventilation shafts.        In addition, there are two 16          other shafts.      One is a men and materials shaft that will be 17          used for carrying men and materials for operations purposes.
18          And the fourth shaft is the emplacement exhaust shaft.
19                      So in the final repository, there will be four          l 20          shafts and two ramps.      And those would be openings 21          connecting the surface to the underground.
22                      MR. MOELLER:    Excuse me, the last one, the 23          emplacement exhaust shaft, what is that?
24                      MR. GUPTA:  That would be the ventilation exhaust 25          shaft. They would be there to make sure that no

r-( j\  1 radionuclides migrate that would be trapped in this filter 2 building up here at the top of the shaft. So essentially, 3 this is a ventilation chaft for the exhaust from the 4 underground.                                                                  l 5          Now in the un'derground facility, there will be                    ,
I 6 miles and miles of tunnels op drifts as we know them.      There            ]
7 would be three long drifts, three main ones known as the                    l l
8 waste main, another known as tuff main, and the third one                  l l
9 will be known as the service main, having different purposes 10 there.
11          The entire area will be divided into seventeen or 12 eighteen panels where the waste would be emplaced. And each 13 one of them, each panel would have several miles of drifting
(~)  14 for waste emplacement. Altogether in the underground v
15 facility, there will be a hundred miles or more of drifting.
16          For the sealing point of view, all of these 17 openings may need to be sealed at the final closure time.

19          MR. STEINDLER:    How about the bore holes, are not 20 the bore holes sealed off?
21          MR. GUPTA:  A good point. In addition to all of 22 these openings, DOE is proposing a number of bore holes for 23 exploration purposes, and those bore holes will need to be 24 sealed.

4          MR. GUPTA:    There are going to be a large number                    i 5 of holes within the exploration facility for testing 6 purposes. And depending upop what is found in that area, 7 there may be a need to seal those holes as well.
8          As I just mentioned, the term sealing as used by                      ,
9 OOE, it refers to all activities that would be associated 10 with closure of the underground facility, the shafts, ramps, 11 and bore holes.
12          Now seals may be required to limit water flow from 13 the surface into the underground facilities, the water being
(}  14 caused by the flooding and other rainfall events.      Also the 15 seals may be needed to avoid the flow of air outside of the 16 underground facility.
17          MR. STEINDLER:      Excuse me, are you going to touch 18 on that again some time, that is the rationale behind the 19 restriction of gaseous flow?
20          MR. GUPTA:    Yes, I will.
21          MR. STEINDLER:      Okay.
22          MR. GUPTA:    The two sources of water, as I 23 mentioned, could be from surface flooding or there could be 24 direct infiltration through faults.      And for air, the 25 concern is that air might come out through the natural i

6                      Are there any ques,tions?
7                      MR. MOELLER:      Yes.        How many seals are there, I 8          mean is there a minimum number of seals on any given shaft?
9          Like I see four on the vertical shaft here.                                    Is that a 10          minimum number?
11                      MR. GUPTA:      DOE's current position is that seals 12          are not needed to meet the requirements of 13          10 CFR 60 to meet the performance objectives.                                    Then to go 14          down and see if there is a potential for water infiltration 15          or there are some other concerns as they will note when they 16          construct the facility'.      And at that time, they may evaluate 17          the need for seals. The number and where they will be 18          locating these and the actual design still have to be 19          decided later on by DOE based on what they find underground.
20                      MR. MOELLER:      There is no set number then?

                      ;  1  sealing of the four shafts.                  The various components of the 2  seals are at the surface of the shaft where it meets the 3  ground surface, there will be a surface cover core, and then 4  there will be a collar core, and these would be concrete
  <                    5  structures.            There will*be an, anchor to bedrock plus.      And 6  then the shaft itself will be backfilled by crushed tuff.
7                      In order to avoid the settlement of this tuff, 8  there will be a number of settlement plugs that would be l
9  placed.            And the number of them remains uncertain at this 10  time as to how many might be needed to control this 11  settlement.            In addition where the drift meets the shaft, 12  there would'be a station plug to support the shaft backfill 13  and to control water infiltration into the drift.
14                      If I could have the next slide.      This is to show O-              15  the detail of the surface cover at the shaft.                  .The shaft 16' would be covered by a rip-rap along the surface cover.                    This 17  is the alluvium that would be the collar core here made of 19  concrete.            And this is the plug, anchor to bedrock plug, 19  that would be grouted and then the shaft backfilled.                  This 20  shows the details of the seals at the surface of the shaft.
21                      MR. MOELLER:    And that rip-rap on the top is 22  10,000 year rip-rap or what?
23                      MR. GUPTA:    DOE's curreat assessment is that the 24  seals will not be needed to meet the performance objectives 25  for 10,000 years.              And the current thinking is that if at Heritage    Reporting    Corporation O                                                    (202) 628-4888 t

()                  1-  all needed the caps need to last only 1000 years.
2                    MR. MOELLER:      When DOE, and we had read that 3  -position, when they present that, are they saying that even 4  if they did not put anything at cil in this open shaft, just 5  let rainwater or whatev'er might run down it, that there 6  would be no problems?                  .
7                    MR. GUPTA:    That is correct.          That is indeed their 8  position.
9                    This shows the details of the settlement plug.
10  Now you will notice that DOE is proposing that through the 11  settlement plug that there will be tubes filled with 12  aggregate.        So if water gets into the shaft, it is able to 13  get out through these settlement plugs and go to the bottom
(}                14  of the shafts.          Their strategy is that if water gets into the shafts that it should be able to drain out through the 15                                                                                l 16  bottom of these shafts'.            So the idea is not to completely 17  seal it but to be able to drain the water out, so that it 18  does not find its way to the waste packages.
19                    MR. STEINDLER:      Is that a position that has been        !
20  accepted by the staff?
21                    MR. GUPTA:    No, we have not accepted it yet.

(%                          1 that might be needed to show the effectiveness of these 2 seals. And we have made a number of comments in our papers 3 on the seals.
4            MS. MOODY:  One of my questions to you is has 5 there not been some con *cern with respect to even sealing all 6 of the holes just for safety, reasons, not necessarily for 7 other reasons except for that?
8            MR. GUPTA:  That is correct. One of the purposes 9 of the seals is to keep the intruders away.
10            MS. MOODY:  That is correct. And that would be an 11 argument that you should seal anyway.
12            MR. GUPTA:  Yes.
13            MR. MOELLER:    But to be sure, and I do not mean to
{}                        14 beat it to death, in other words the seal is primarily to 15 prevent easy intrusion or inadvertent intrusion, and the l
16 seal will be designed if DOE's proposal is accepted that it                        I 17 will be designed not to impede the flow of the water, but 18 what water gets in there that it can flow through and move l
19 on to the bottom of the repository, and then where is it                          l 20 taken?

4          MR. MOELLER:      Yes.
5          MR. GUPTA:    Ahd the, idea was that when water gets 6 in there that the water would be able to accumulate there, 7 and that it will not finds its way ,o the waste packages.
8 And gradually the water would seep int        the rock and 9 eventually find its way to the groundwater able.
10          MR. MOELLER:      I guess that I find or I need to 11 think about it a lot more to understand it better, but you 12 had the Calico Hills which has been described time and time                              i 13 again to us as an impervious barrier between the unsaturated f-            14 and the saturated zones.      And now we are hearing we really
  \J 15 want to penetrate that so that water flow can go on down to 16 it.
17          MR. GUPTA:    Well, it is hydraulically not 18 impervious.
19          MR. MOELLER:      Okay.
!                20          MR. GUPTA:    That the water would be able to go 21 through it.
22          MR. MOELLER:      Would there be anything put into 23 these passageways to take out any contamination that might 24 be in the water?
25          MR. GUPTA:    That is the strategy that DOE is Heritage      Reporting  Corporation O                                        (202) 628-4888
 
17      I 1 using. That all of the water that goes through this rapid (v~)
2 pathways should be uncontaminated.        The pathways are not for l
3 contaminated water. And the design philosophies to keep the                                l 4 water away from waste packages and for all of the water that 5 is uncontaminated find h quick pathway down to the water 6 table.                          ,
l 7          Do you have a question, Ms. Moody?
l 8          MS. MOODY:    I will pass this time.

11 underground drifting at the main repository level.        As you 12 will notice here, the plan for the liner to be terminated 13 just above the repository horizon level.        Below that the 14 liner would be removed.      So that if there is any water that 15 comes through the shaft, it can dissipate into the 16 surrounding ground.
17          The concrete barrier here is placed at the 18 interface between the shaft and the main drift at the 19 repository level, and that would be put into the surrounding 20 rock.
21          MR. MOELLER:    Excuse c.e, what did you say again on 22 that one about water, that even though there is a plug in 23 the drift that it again will permit water to flow?
24          MR. GUPTA:    Let me show it to you.      This is the 25 concrete liner surrounding the face of the shaft.

2                        MR. GUPTA:    DOE's plan is that at closure that all 3    of the liners at the level of the repository would be 4    removed, so that the rock is bare and there is no concrete 5    liner around the shaft.' If water comes down through the 6    shaft, it can dissipate into.the surrounding rock.
7                        MR. MOELLER:        Thank you.
8                        MR. GUPTA:    I just went through the sealing 9    concept for the whole shaft.                    There are similar concepts for 10        the ramps.              There will be two ramps in the final design.
11        And DOE plans to seal the ramps in just about the same 12          fashton.            There will be a surface plug, and the ramps will l
13        be backfilled with crushed tuff, and there will be a plug 14        placed in the intersection of the ramp and the main
(~)T
              '15        repository level.
16                              This picture'shows the details of the ramp plug at 17        the surface.                There will again be rip-rap placed at the face 18        of the ramp, and there will be a concrete plug to see if any 19        water does not seep in and also to keep the intruders away.
20                              MR. MOELLER:      And again that will be lined, it 21        will be lined only up to the repository itself or that last 22        seal, do you have a liner to the left of the last plug?
23                              MR. GUPTA:    It does not show.                I have not seen any 24        discussion on the ramp for this situation.
25                              Now just to talk about the shafts and the ramps.

19 l' This picture shows the sealing concepts for bore holes.
2  Bore holes, again there would be a bore hole cover, a 3  concrete cover at the top. There will be rip-rap placed at 4  the top. The bore hole will-be backfilled with granular l          5  material depending on what the need is.
6            Now coming to the underground facility.                    This-is 7  an area that our rule does not cover, the sealing of the 8  underground facility. But there will be about a hundred 9  miles of drifting underground, there will be a number of 10  faults and fractures that will be intersected by these 11  drifts and they may need to be sealed.
12            There are a number of concepts that DOE has for 10  sealing those at this time.      Depending on what they find, 14  they might chose one or the other of these.                      One option is 15  that-if the fracture is like this, that they might put a l
16  sump at the bottom of the drift where the water can
: 17. accumulate for some_ time. There will be additional drainage 18  holes through which the water can seep below the drift 19  level. So the idea is not to plug the water that comes 20  through the - fract tre, but to let it drain down below the 21  bottom of the drift.
22            And just to emphasize again, the idea is to deal 23  with water only. The movement of gaseous radionuclides 24  through these faults is not addressed in the sealing 25  concepts of DOE.

6            There are two other options shown here.      One is to 7 put a concrete barrier here on one side with grouting on one 8 side of the fault.      The other concept is to put bulkheads on 9 both sides and then fill it with free draining crushed tuff        ;

21                MR.

6                    MR. GUPTA:  Six inches or something like that.
7          The only concern could be some fresh water zones that could 8          find its way through the fractures.

10                      MR. HINTZE:  Has any consideration been given to 11            the fracture of the liners as a result of movement along 12            faults, and how is that taken into consideration?
13                        MR. GUPTA:  DOE is designing the liners for
                      ;G          14            seismic loading in nuclear plants.      And their design

16                        MR.

(~)    1                Is the position of DOE regarding let the water
              \_/
2    come and we will get rid of it someway or other down and 3    out, is this simply an admission that there is no way that 4    we are going to keep water out of the system?
5              MR. GUPTA:    The thinking is that the water 6    quantities are going to be extremely small.        That is the 7    perception that we get.      And assuming that if the water 8    quantities are really small, then there would be no concern.
9    Some of these questions will indeed be answered when we go 10    down and see the rock.
11              MR. HINTZE:      Thank you.
12              MR. MOELLER:      Bill, you know that I am not a 13    mining engineering, but it seems to me that from what we are 14    hearing this morning that DOE is acknowledging that water
(.'')  15    may gain access and that they are going to take care of it 16    if it does. And the idea too of putting the collection 17    basin beneath a fracture so that if water does come down            i 18    that they again can take care of it makes sense to me.        You 19    know, I want to hear more, but it makes sense.                      j 20              MR. HINTZE:      It is certainly one of the viable 21    alternatives.
22              MR. GUPTA:    It indeed makes sense. The only 23    concern that the staff would have is whether those drainage 24    passages could remain effective for the number of years that 25    DOE is relying on that drainage.      And some testing, or some r~g                      Heritage Reporting        Corporation

MOODY:  Well, also tied to all of this 4 designing is the fact that the assessment as to predictions,  !
5 whether predictions for*the n9xt 1000 to 10,000 years may 6 have some long-term predictability. Because like you say, 7 if you are going to design a repository for six inches of 8 rain per year, you are predicting that that six inches will 9 go on for the next 10,000 to 100,000 years.                    l 10          MR. GUPTA:  That is absolutely right.
11          I will now quickly go over the regulatory 12 requirements that must be met for the seal design, for seal 13 testing, and for the performance of the seal.
f w,        14          The first and most important one is 60.112. It (J
j                      15 deals with the overall system performance. The regulations 16 do not directly require the seal to meet any performance 17 objectives. Rather for the overall system, the requirement 18 is that the geologic setting shall be selected and the 19 engineered barrier system, and the shafts, and bore holes 20 and their seals shall be designed collectively to assure 21 that the EPA standards are met.
22          So if DOE decides not to assign any performance or 23 allocate any performance to seals, then the engineered 24 barrier system and geologic setting will have to take care    ;

()                                                  1            or allocated any performance at all.
But we are not saying
!'                                                          2            that:that is what we are looking for.            We are known on being                  <
l 3            on'the conservative side,-and it would be prudent that DOE
: 4.          does design seals in a way that can' contribute some 5            performance to the over'all.      ,
16                    With respect to the design of seals, the
                                                      .7                  requirements are that seals for shafts and bore holes shall 8            be designed so that following permanent closure they do not 9            become pathways that compromise the geological repository's 10                    ability to meet the performance-objectives.              This is a broad 11                    based requirement for the design.
12                              If I could have the next slide, please.                    For the 13                    sealing materials and how these seals will be placed, the 14                    requirements of 60.134 talks about the materials and
          )
15                      placement methods. And again the requirement is that the 16                    materials and placement method shall be selected to reduce 17                    the potential for creating a preferential pathway.and for 18                    radinuclide migration.
19                                With respect to the testing and the performance 20                      confirmation program.      Since seals have to be placed at the 21                      closure time which is some time from now, the DOE has some 22                      time to collect a lot of data on the performance of seals.
1 23                      The requirements though call for the program of performance 24                      confirmation to begin doing site characterization.                    And the 25                      program shall include in situ monitoring, lab and field                                ;

a 28 1 testing, and so on and so forth.
(~))
u 2            As far as the testing of the design of seals, the l
3 requirement of 60.142 states that during the early or 4 developmental stages of construction, a program for in situ 5 testing of such feature's as bore hole and shaft seals and 6 other components of seals sh,all be conducted.      And the 7 testing shall be initiated as oarly as practicable.
8            MR. MOELLER:    Now none of this has begun as of 9 today?
10            MR. GUPTA:    No. There has been some lab work that 11 has been done on sealing materials.      But at this time, that 12 is at a standstill to my knowledge.
13            MR. STEINDLER:      I know that you folks have already 14 written those regulations essentially into concrete, and I f-)
Am/
15 am sorry for that pun, but I do not understand how you 16 expect a licensee to test bore holes that are sealed on a 17 post-closure basis.
18            Once the issue is closed and the shafts are 19 filled, what sort of testing do you expect somebody to do?
20            MR. GUPTA:    The testing will have to start way 21 early. It is not that we are asking for tests to be done 22 after the closure. The testing is to be done before closure 23 and before the license is given for closing the facilities.

5          MR. GUPTA:  Obr requirements call for testing of 6 seal design as it would be.    ,
7          MR.

GUPTA:  I do not know if after closure that we 11 have any requirements. I think that we close the facility 12 and go home.
13          MR. MOELLER:    As I recall too, and I hope that my
/~    14 memory has not slipped me completely, but like in terms of b}
15 environmental monitoring, once it is sealed up you quit.
16          MR. STEINDLER:    Fine. I understand that. But I 17 am trying to reconcile that fairly obvious point with what I 18 think I see up there.
19          MR. GUPTA:  Jim, do you want to add something?
20          MR. WOLF:  Yes. I am Jim Wolf, the General' 21 Counsel's Office. The idea is that at the time of permanent      .
22 closure that of course '.he Commission should have the 23 confidence that the seals and everything else are going to 24 operate when they are closed.      But there is still a further 25 regulatory regimen that exists afterwards, from that stage Heritage  Reporting Corporation

                          '2  license.
3            Now how the regulators will implement that remains 4  to be seen. But there has been.a good deal of discussion 5  about the desirability 'or feasibility of post-closure 6~  monitoring which could be considered if it was deemed 7:  necessary and appropriate.
8            So the point is that if there is felt.to be a need 9  even after permanent closure for any further activities to 10    be undertaken that the Commission retains jurisdiction over 11    the Department of Energy so that could be done.                                                            But that is
                        '12    really getting decades into the future.                                                    And so the 13    regulations provide the flexibility necessary to deal with 14    the situation in a reasonable way at the time.-                                                          But I do not

15    think that it is any more specific than that.
16              MR. GUPTA:  The next requirement that I am going 17    to address here is 60.24. It states that the license 18    application and the' environmental report shall be as 19    complete as possible in light of the information that is 20    reasonably available at the time of docketing.
21              And what we are referring to in this rule is that 22    when the license application is submitted that there should 23    be sufficient information on seal material, the replacement 24    method, and the performance of the seal, so that they can 25    evaluate the adequacy of those at license application time.

I  )                                      1              Now I will go to the next topic of my discussion 2  this' morning.        Why is there.a need for-a technical position 3  on the seals.        And there are a number of issues here that I 4  would like to point out.            The first one is that DOE has 5  concluded that there is'no need for seals to meet the 6  requirements of 10 CFR 60.112                                  However, DOE has stated that 7  it plans to install seals.                  And the thinking is that they 8  may later decide that need to allocate some performance to 9  seals.
10              And I think that it would be important for us to 11  provide some' guidance, that if that is the case then.what 12  performance criteria should be used to design the seals and 13  allocate performance.
()                                        14              MS. MOODY:        Before you leave that, just quickly                                                                                                      i 15  state that if DOE has concluded that there is no need for 16  seals, what is their criteria for concluding that or what 17  did they use, just low total rainfall or what?
18              MR. GUPTA:        They have submitted an analysis both 19  with respect to the water infiltration and with respect to 20  gaseous outflow.        Based on their calculation that they have 21  presented as-to how much water they can allow with time from 22  day zero to 10,000 years within the facility, they are 23  saying that their estimate of water that will come down in 24  the underground facility is significantly less than the 25  amount of water that they can allow come underground and                                                                                                                )

2            The same conclusions have beer made with respect 3 to the air outflow. The performance requirements that they 4 have used state that you can allow some 25 percent of the 5 air from the undergroun'd facility to escape outside.                            And 6 their estimates are that much less will go out based on 7 their modeling of the facility.      And therefore even if the 8 seals are not there, the facility will meet the performance 9 objectives. Now of course, you have to realize that there 10 is hardly any data at this time.
11            MS. MOODY:    That was the issue of raising the 12 whole point. That if you are going to do some calculations, 13 there has to be some cross-check to see whether or not those
{}  14 calculations are meaningful given the site itself.                              So what 15 you are saying is that some preliminary calculations 16 indicate that seals may not be needed.          But if they are 17 going to continue to operate in that mode, they still have 18 to collect some data which may or may not back that up.
19            MR. GUPTA:    Absolutely.      I think that that is 20 exactly what we are saying.
21            The other point that I would like to stress here-22 is that the seal design concept for unsaturated medium are 23 so different than the concepts that are originally thought 24 out in writing the regulations.      As I pointed out earlier, 25 doe is stressing more on the need for keeping the drainage Heritage    Reporting  Corporation

The water comes in and gets up, rather than 2 plugging the water in and not letting it in.                                            The concepts 3 are so different that it seems that some guidance is needed 4 to DOE as to what requirements have to be met for those 5 concepts.                          ,
6          By the same token that DOE is not allocating any 7 performance to seals at this time, they have not put them on 8 the Q-list. And the staff feels that we naed to clarify our 9 Q-list requirements for seal position in this technical 10        position document.
11                  MR. STEINDLER:        Is the discussion concerning the 12        Q-list before the Q-list technical position document or to 13        so clarify?
()                                                14                  MR. GUPTA:    It is just a clarification of a 15        restatement of the same position specifically dealing with 16        seals. The position that we have taken in this document is 17        exactly what we are talking in NUREG-1318.                                            They have to use 18        that document to come up with the Q-list requirement.
19                  For performance confirmation, DOE's position is 20          that they do not need to start any in situ test program 21          until after the license is issued to them for construction.
22          And the staff feels that enough data should be collected 23          before license application on seals, so that when the 24          license application is docketed that we can review it to 25          ascertain whether seal technology is reasonabay available so O                                                                      rie 9-        eerei e (202) 628-4888 cerror eie-                                                                1

'{ }
2  And we need to clarify these requirements, and the technical 3  position would be a good way to do that.
4            The next position on the need for a seal technical 5  position is that the sthff feels that for long-term 6  performance that seals have to last for a long time.        It 7  would be difficult for DOE to demonstrate that seals can 8  last for a long period of time.        And therefore if DOE needs 9  to locate performance to seals, DOE should try to minimize 10  the need for seals by using appropriate design measures, 11  with the openings at higher levels and things like that, but 12  DOE does not have to depend on seals.
13            Another reason why we thought that.a technical 14  position was needed on seals was that we need to clarify 15  predicting the longevity of seals for long-term 16  uncertainties that have to be considered in meeting the 17  requirements of 60.112.
18            Now we start with writing the technical position.
19  Whenever the staff develops a technical position, we are hit 20  from two sides.      Some people come back and say you are 21' reiterating the regulation, what is written in the rule, and 22  why do you need a technical position.
23            If you go beyond that and try to explain the 24  regulation, people come and say you are using the technical 25  position as a vehicle to generate or create new rules and Heritage    Reporting  Corporation

4                        It is the same thing on the concept of whether it 5              .is too prescriptive or too general.        If you try to specify 6              things that seem like provid,ing some guidance to DOE in 7'              terms of some specific numbers and specific quantities, 8              people say that you are being too prescriptive.            If it is 9              too broad, then people wiil come back to you and say it is 10              too general and it is of no use to us.          So you nave to 11              really walk a fine line when you develop a technical i

13                        What we are saying up front in this technical 7
14              position is that technical positions are not substitutes for U          15              regulations. This is one way that DOE can demonstrate how 16              they can meet the requirements of the regulation.            And the 17              staff will accept alternative positions if DOE can justify 18              that they will meet the applicable requirements using 19              alternative means.

9                  MR. GUPTA:    We have addressed it in a general way, 10            but we have not been very explicit as to how the thermal 11            effects of emplacement should be accounted for.
12                        MR. STEINDLER:      I understand that, but have you at 13            least asked in some fashion or other, and I do not see it

22                        MS. MOODY:    Well, each one of those points 23            geologically speaking are very important.      And it is not 24            only part of the effects on emplaced waste, but gaseous 25              outflow and potential changes in water level, and the future

          '                        of geologic and geochemical processes.            Those are all 1
2  important. And in terms of post-closure, they are very 3  important. So to add to what Marty said, my question is why 4  did you not address each one of those points.
5              MR. STEINDLERI:        We pre saying that DOE does not 6  have to account for these.          They have to account for all of 7  the items explicitly in analyzing the performance of seals 8  over a long period of time.            At this time, we did not have 9  sufficient guidance for DbE to give on these issues, and we 10      chose not to include that in the technical position.
11                  MR. MOELLER:        On the gaseous outflow with respect 12      to the source term, I presume that DOE in testing the waste 13      canister or the spent fuel itself and so forth will have 14      data on that or that they are gathering data on that?
({ }
15                  MR. GUPTA:      Would you repeat your question, 16      please.
17                  MR. MOELLER:        In terms of gaseous outflow, are 18      there not data being gathered to determine the source term, 19      what you would anticipate in the way of gaseous outflow over 20      X number of years of spent fuel storage?
21                  MR. GUPTA:      I am not familiar with that part of 22      the program. There is nobody here to answer that question.
j                          22                  MR. MOELLER:        Now back on the comments by Doctors 24      Moody and Steindler, you have explicitly stated in the 25      technical position that these items are not -- well, you say

3          MR. GUPTA:    It is stated up front in the 4 introduction that we have not explicitly addressed these 5 items in the technical positign.
6          MR. MOELLER:      Okay,.
7          MR. VOILAND:      Would you expect that these various 8 environmental changes that might occur would have any 9 different effect on the seals than it would have on the host 10 rock itself?  It seems to me that this would be a secondary      j 11 or tertiary order effect.
12          MR. GUPTA:    Well, some questions were raised 13 earlier. The long-term effect could change the environment
(}    14 in the quantities of water that could come in.      The teutonic 15 movements for example could affect the seal performance.
16          MR. VOILAND:      It could upset the characteristics 17 of the host rock as well.                                        ,
18          MR. GUPTA:    That is true.
19          Just briefly summarizing some of the salient 20 technical positions that we have stated in this document.
21 The first one is we expressed the need for appropriate l
22 design features for DOE to reduce the need for seals.      Just 23 to be on the conservative side, to use design features that j                                24 the need for seals are reduced.      For example by using l

2    where the infiltration of. water is reduced.                                                                                                l 3                On 0-listing, the position that we have taken is 4    that DOE should use NUREG-1318 to determine the Q-list.                                                                                And 5-    if seals are determined *not important to waste isolation, 6    then they can be removed from the Q-list.                                                                    But if they are 7    included en the Q-list, then sealing activities should be 8    covered by an adequate QA plan.
9                MS. MOODY:  I think getting back to your previous 10    slide that when you say that if seals are determined not 11    important to waste isolation, I think just that statement is 12    something that certainly not only in the public arena but 13    also in the technical arena can be argued.                                                                                In other words,  l 14    what DOE could be trying to state that it is not needed can O  15    be turned around and argued both technically and politically 16    that they are needed.
17                Has DOE put forward a paper at this point in time 18    that articulates why they think that sealing is not needed?
19                MR. GUPTA:  DOE's current position on the Q-list 20    is that there is no item, zero items, even including this 21    package as any item on the Q-list. Because there is nothing 22    that they think is important to safety or important to waste 23    isolation. And that is where they are coming from.
24                The NUREG-1318 takes a position which is quite 25    different. It says that unless DOE shows otherwise that Heritage    Re. porting          Corporation p)

(}                                      1    things are not on the Q-list that every item of importance 2    competence should be included on the Q-list.                              And it could 3    be removed if and when sufficient data is collected and you 4    can show in a reasonable manner that you do not need to put 5    it on the Q-list.                                  ,
6                      MS. MOODY:          Then y,ou are stating that as far as 7    NRC's view is at this point then that there is not the data 8  available to prove that the seals or the waste package are                              j 1
9  not needed.              So then by definition they are needed, or they                l 10            should remain on the Q-list.                          I do not see where the data is 11            to prove that they can be removed.
12                                MR. GUPTA:          That is indeed our position at this 13            time, that the data is not sufficient to exclude the seals 14            from the Q-list.
15                                Now with respect to the testing information 16            required at the license application time, we have taken a 17            position in the technical position that the preliminary data 18            from seal testing should become available before the license 19            application is submitted.
20                                The next technical position deals with the 21            uncertainties in predicting the long-term behavior of seal 22            performance.              And what we are stating in the technical 23            position is that in evaluating the overall system 24            performance that DOE should consider uncertainties in all 25            areas before they say that no allocation to seals is needed

(}                                          1 in meeting the overall system performance objectives.
2            Just to recap the entire talk here. The sealing 3 concepts for unsaturated medium are very different than for 4 saturated medium. We are not talking about plugging the 5 water, but we are talking about pluggage and drainage for a 6 ?7ng time. And therefore we. thought that a technical 7 position and guidance on those design concepts is needed at      !
8 this time.
9            The technical position provides one way of 10 complying with the regulations.      And what we have emphasized 11 in the technical position is that DOE should use design 12 features to reduce the needs for seals, and collect enough 13 information before license application so that the staff can 14 evaluate whether technology is reasonably available to seal v
15 a closure. And then use redundancy and consideration of 16 uncertainties in analyzing the long-term performance of the 17 overall system.
18            MR. STEINDLER:    A couple of questions. My reading 19 of the technical position paper that I have leads me to ask      i 20 a number of questions.                                            !
21            First off, am I correct in interpreting this          !

43 1        have written this document to guide them in that analysis?
2                    MR. GUPTA:  That may not be the way that I would 3        characterize it.
4                    MR. STEINDLER:    I am sure that it would not be.
5        But I am trying to see what the basic assumption was that 6        you used to even go to the trouble of writing this document.
7                    MR. GUPTA:  Our thinking at this time is that 8        there is no sufficient data avai2.able at this time to make 9        any conclusions one way or the other with respect to 10          allocating performance to seals.      And DOE should collect 11          enough information and enough data so that reasonable 12          conclusions can be drawn based on the information from 13          in situ testing and lab tests.
14                    MR. STEINDLER:    That is not what this technic 21 15        position however states.        The technical position gives an 16          outline of the approaches to be used based on the assumption 17          that there is a need for performance of a certain kind or at 18          a certain level of that seal.
19                      MR. GUPTA:  That assumption is on the basis that 20          if DOE decides to allocate performance after they have 21          collected information and data that then they should go 22          through all of this process.
23                      MR. STEINDLER:    Fine. The second question deals 24        with my topic on the release of gases.      The introduction to 25          the technical position states as one of the goals of a seal, Heritage Reporting Corporation O                                                      (202) 628-4888

2 up, but in effect to prevent, I guess is the word that you 3 used, prevent significant amounts of gases from escaping        3 4 through the shafts. There is an implied I think assumption 5 here, namely that that prevention is important.
6          Have you or the Department indicated that that is 7 a worthwhile endeavor and therefore should be part of the 8 technical position that the staff should take?                  ,
9          MR. GUPTA:    Well, on the gaseous outflow from the 10 underground facilities, that is an area that Rvd is 11 undertaking at this time. The sense and opinion at this      t 12 time in my judgment is whether DOE has conclusively shown at 13 this time that they do not need to rely on those, whether        )
    ,_  14 there is enough data available at this time to conclude          .
k    15 that.
16          MR. STEINDLEk:    I guess that I am confused. I do 17 not think that we are in the process of adjudicating the 18 32eue. I thought that we were in the process of defining le the position of the staff concerning bore holes seals.      So I 20 an trying to find out why it is that repardless of what the 21 Department has written so far, why is that the staff 22 believes it necessary to insert in one of the major 23 objectives for these bore hole seals the significant 24 reduction of gaseous emissions.

2 now trying to plug in four, five, or six different places,          )
I 3 but the sieve remains. Why bother putting that kind of 4 requirement on seals.
5          MR. GUPTA:    W' ell, first of all, let me address in 6 two different ways. Number pne, the escape of gases is 7 important from our perspective.      In 1985 just to give you 8 some background, DOE submitted to us a preliminary                f 9 performance assessment. ind the results that came out of 10 that analysis that DOE had made was that there was not much 11 of a problem with water 1.cflow but that for gaseous outflow 12 that there was a marginal factor of safety.      And gaseous 13 outflow has been a concern of DOE as well as for the NRC
(}  14 staff.
15          Now how you can control it is another point here.
16 All of the manmade features, whether it is a shaft, or a 17 bore hole, or ramps add to the already openness of the 18 geologic setting. And I think that it would be prudent to 19 seal them in a way that you do not create more openings than 20 already exist. If you cannot show by analysis that it will 21 meet the performance, then DOE is in trouble with respect to 22 showing the suitability of this site.      But whatever manmade 23 openings are there, I think that you can do something about 24 those, and that is what DOE intends to do.

5    and the suggestions thab are pontained therein match the 6    need to have retrievability paintained for a certain period        i 7    of time, has the staff examined that role and that issue?

9              MR. STEINDLER:    Yes, post-closure.
10              MR. GUPTA:    Jim, do you have any thoughts on that?
11              MR. WOLF:  There is no retrievability requirement 12    after permanent closure, so I do not see that there is a 13    problem there.
14              MR. STEINDLER:    Well, you do not see then that O                      15    these shafts would be sealed between the completion of the 16    loading of the repository and the final closure, is that 17    what you are saying?
18              MR. WOLF:  DOE certainly has the option to do that i
19    as long as retrievability -- in other words, you can              ;
20    backfill during that time, but you must maintain the 21    retrievability option until permanent closure.
22              MR. STEINDLER:    Then I take that to mean that this 23    technical position does not address the issues at all, so it 24    is based on the assumption that these seals would be put in 25    after the requirements for retrievability has expired?

6          MS. MOODY:        One la,st comment. On the slide that 7 you have of this technical position when you say the very 8 first one, use of design features to reduce need for seals,
                                                                        ^
9 I mean I would completely reword that and say use of design 10 features to facilitate drainage in the repository 11 construction, all of the key she.fts and everything, waste 12 emplacement rooms. Because that is an important item that 13 you emphasized over and over again, that they want drainage.
f'N                    14          Well, that is a key thing in the design features O                    '
15 that you could then say would facilitate perhaps not meeting I                                  16 the classic seal. What I am trying to say is to tell you 17 that the reduced need for seals is somewhat a supposition 18 that DOE is correct 4.n saying that they do not need them, 19 and I am not convinced that they are.
20          MR. GUPTA:        A couple of things with respect to 21 drainage. Number one, whether they would remain effective 22 for a long period of time is a question mark.          You can 23 definitely do something about reducing the infiltration by 24 locating the openings in a way and using the construction 25 techniques that do not create additional damage and pathways

                                                            'l  to facilitate water infiltration.
2            With respect to drainage, the thinking here is 3 that you are facilitating the drainage on uncontaminated 4 water. Now what happens if some water gets to the waste 5 packages and then the s'ame pathways become-rapid pathways 6 for radionuclides to the water table.                So those are the 7 questions that one has to address in thinking about drainage 8 concepts.
9            MR. HINTZE:    Mr. Chairman.
10                  MR. MOELLER:    Yes.
11                  MR. HINTZE:    Related to your first comment up 12      there. The main lever, as I understand it', for the change 13      in the technical position is the movement from a saturated e                                            14      to an unsaturated medium.        I would suggest that perhaps not k
15      as important but certainly another major lever here is the 16      possibility that we do'have fracture flow rather than porous 17      medium flow. And in my reading of the document, this is not 18      brought out and is not emphasized.
19                  And it would seem to me, and I have not thought 20      through the whole process myself, but simply the integrated 21        flux might be the same, the integrated flux of water might 22        be the same in fracture versus porous medium flow, but the 23        rate of that flux may be highly variable under those two 24        conditions. And I would think that would be a very 25        prominent factor in the effectiveness of the barriers or the

MOELLER:        A couple of other questions 21  continuing on this subject.            It seems to me that in.your 22  technical position of course you say that, " Provisions for 23  rapid drainage of uncontaminated water through the 24  repository horizon can reduce the risk of water contacting 25  the waste packages."      So you are encouraging or it sounds i

(_/  1 like you are encouraging DOE to quickly get rid of any water 2 that gets in or near the repository.
3          Then you say, "However such a drainage system can 4 also provide pathways for rapid flow of contaminated water 5 to the accessible environment,"      So as I read it, you aro 6 giving them a carrot and then you are taking it back.
7 While both statements are undoubtedly true, I do not know if 8 they are totally compatible.      That is just on reading in it.
9          Some questions.' When was the decision made that 10 you would handle this as a technical position versus 11 rulemaking or how do you make that decision, I suppose that 12 is a legal statement?
13          MR. GUPTA:    Brian, do you want to handle that.
()  14          MR. THOMAS:    Brian Thomas, waste management, the 15 directorate staff. The decision was made to proceed with 16 this as a technical position in early January 1988 upon 17 review of the DOE CDSP. And the decision on rulemakings per a
18 the division's policy is to try to clarify uncertainties,
[
19 regulatory uncertainties, in the regulations.      The technical 20 position is more for the purpose of conveying to DOE 21 criteria that if used by DOE, of course they have a choice 22 to use other criteria, but if used it would be acceptable to 23 the NRC as a method of demonstrating compliance with the l      24 regulations.
l      25          MR. MOELLER:    Having said that though, then if you i( )                  Heritage    Reporting Corporation (202) 628-4888

7            MR. THOMAS: .The rulemakings focus more on 8 ambiguities and clarifications needed in the regulations.
9 Technical positions focus on the technical uncertainties 10 which are indeed derived from some regulatory uncertainties, 11 but the technical uncertainties deal more with the DOE's 12 methodology for demonstrating compliance.      Their tests and 13 analyses and that type of detailed technical information.
14            MR. MOELLER:    Okay. Thank you.
( ')
15            MR. GUPTA:  Dr. Moeller, if I could amplify on 16 that. There are four areas in this technical position that 17 could be reasons for considering rulemaking versus the 18 technical position, and we have been talking about that for 19 some time. Number one, in the technical position, we have                i 20 taken up the subject of sealing the ramps and the 21 underground facility. And the rule does not talk about the 22 sealing of the underground facility or ramps.      It basically 23 talks about bore holes, shafts, and bore hold and shaft 24 seals. So that could be one reason for considering whether 25 you can extend bore holes and shafts seals and underground n

52  ,
()                            1      ' facility seals.
2                  The second point would be the concept of the 3        drainage itself. The way that the regulations are written, 4        they do not really explicitly deal with tha issue of 5      . drainage as a concept fbr seals. And that could be another 6        reason for considering or cl,arifying the regulation itself 7        rather than addressing it in the technical position.
8                  One of the more important points is on the 9        treatment of the fractures and faults for gaseous pathways.
10        There is no provision in the rule which explicitly talks 11        about those issues and what could be the requirements for 12        those.
13                  And lartly, we do not touch on that in great detail here, but there has been some discussion as to how
  '( )                          14                                                                      l 15        much data that we can really require DOE to provide us at 16        license' application time. The rule is clear but not very  I 17        explicit. And if one were to taking rulemaking aside, one 18        could clarify these issues as to when DOE should start, how 19        much testing, and provide how much data at license 20        application time.
21                  MR. MOELLER:    Okay. That is helpful.
22                  Once again when will DOE probably begin their 23        testing of their seal designs?
24                  MR. GUPTA:  DOE's position that they are mainly 25        going to focus on laboratory testing for quite some time.

3                  MR. MOELLER:    Okay.
4                  MR. GUPTA:    And would not start in situ testing in 5  the underground main teht area when they go about testing 6  for the exploratory shaft facility.          The interpretation that 7  doe has of the regulation is that our rule does'not require 8  them to initiate any in situ testing before the license is 9  issued to them for construction purposes.
10                  MR. MOELLER:    Another comment. On page eight of 11    your technical position, you point out once again that the 12    shafts, bore-holes, and the seals shall be designed to 13    assure the releases of radioactive materials, this is item 14    number nine,'to the accessible environment following 15    permanent closure conform to EPA standards.          That, you know, 16'  is a major statement, because this committee has looked into 17    the problems of confirming conformance with EPA standards, 18    and those we think are quite complicated.          Well, I think 19-  that takes care of my comments.
20                  Don, did you have anything?
21                  MR. ORTH:    Well, I have been jotting down notes.
22    I have not had any real questions.
23                  MR. MOELLER:    Full your mike over, Don. Thank.

54                I 1        people rather than questions.                                      If even there is a small 2          probability that seals might be decided on, DOE really 3          should proceed as if they are needed.                                                                                                  Even if.they are not 4        allocated performance, the public perception may make it 5          very prudent.                          And the hechnical position, you asked the 6        question why would they proceed with it, it would be very 7          useful for DOE in guiding the work that they need during 8        characterization regardless of how they are going to decide.
9                    MR. MOELLER:                          Yes.            I think that Dr. Moody had 10                    . brought up that point.                          And the whole thing is that you can 11                    save yourself a lot of time if you simply acknowledge at 12                    this stage in terms of public perception that the public 13                    will see a seal as needed.                                    Bill.
14                                MR. HINTZE:                        There are comments in the paper that 15                    we have looked at here regarding minimizing the number of 16                    drill holes.                          I think that somehow or other if that could be 17                    emphasized some bit that it would be worthwhile.                                                                                                      As we 18                    noted in an analogous type of approach to EPA standards 19                    regarding landfill sites and filling into landfill sites and                                                                                                                  j 20                      the possible contamination of the water table, it is very 21                      important that one perform as many tests as possible of an 22                      indirect nature that are non-intrusive into the volume that 23                      is of concern.

19            MR. BUCKLEY:    Good morning. My name is 20  John Buckley. I am also with the Engineering Branch, 21  Division of High Level Waste. It is my pleasure to be able 22  to speak with you this morning to give you a brief summary 23  of the public comments that we received. And my focus this 24  morning will generally be to try to tune into those comments 25  which were not in 100 percent agreement with the NRC staff.

l                        4            (Slides shown.)
5          As you can se'e from,this slide, the development of 6 this technical position started in January of 1988.                                    An 7 internal draft was presented and completed in June of 1988.
8 That draft was then passed around through the NRC staff for 9 review and comment, and a'public comment draft was completed 10 in September. Based on the comments received from the 11 public, that draft was then revised, and what we know have 12 is the final draft technical position which was what was 13 presented to the ACNW for review.
      ,,              14          Now I would like to focus on a discussion on the
    '''                15 public comments that were received.            As can be seen from 16 this side, the NRC received four sets of public comments.
17 The U.S. Bureau of Reclamation provid.ed three comments.                                            The 18 U.S. Geological Survey provided one comment.                              The State of                                          j 19 Nevada provided 32 comments.        And the Department of Energy 20 provided 30 comments.        That was for a total of 66 public 21 comments.
22          As you may recall from your review of the 23 technical position, the technical positions themselves are 24 organized in four main topic areas.            What this slide 25 presents are the number of comments that were received in f                                Heritage      Reporting    Corporation I

L l                                                                        59 (m_)  1 each of those technical position areas.      I have also added a 2 fifth group which I call here introduction to take up any 3 slack which includes the comments which were general 4 comments on the content of the technical position as well as 5 comments on the introduction and Section 2 of the technical 6 position.                      ,
7          As can be seen here, the majority of the comments 8 which were received focus on the introduction section or 9 general comments as well as on the Section 3.1 of the 10 technical position which is design considerations.
11          What I would like to do now is to give you a brief 12 summary of the major public comments that were received.
13 The Department of Energy and the State of Nevada expressed
(}    14 sharply contrasting views of the overall worth of this 15 technical position. In the transmittal letter from the DOE 16 transmitting their public comments to the NRC staff their 17 letter says, "In general, we believe that the staff has 18 prepared a good technical position, a draft which will lead 19 to useful regulatory guidance."
20          On the other hand, the State of Nevada points out 21 that this technical position provides a little guidance or 22 insight into how the NRC will review the performance 23 assessment and design. And it further goes on to say that 24 the entire technical position could have been summarized by 25 saying that the design of the seals should be such that they t

1 meet the performance objectives of 10 CFR 60.
i 2                                  Actually we received three comments on the            1 3 introduction or general comments on the content of the 4 technical position.                          The first one here was from the State 5 of Nevada.                          And it says*that,,"The technical position 6 appears to be deficient in regulations regarding drainage."
7                                  The NRC's point of view on this topic is that 8 although the regulations, 10 CFR 60, do not specifically 9 mention drainage, since DbE has listed drainage as an 10 integral part of their sealing system that we right now at 11 this time feel that the sealing requirements are adequate.
12                                  The following two comments listed on this slide 13 come from the Department of Energy.                            The second comment that
(~)
v 14 is listed on this slide from the DOE says that, "The 15 technical position contains guidance on topics which are 16 inappropriate for this'particular technical position. "
17 They state examples such as overall system performance that 18 is mentioned, and quality assurance is mentioned.                            Location  j
                                            , 19 of shafts, ramps, and bore hole seals are mentioned.                            And 20 they feel that those are inappropriate.
21                                  The reason that the staff put these topics into 22 this technical position is that we feel that any topic which 23 may have an effect on the performance, the design, or the 24 testing of seals should be included in this technical 25 position, and that is why they are in here.                                            I

                                    .      1            The last comment on this particular section from 2  the DOE says that the technical position imposes new F
3  requirements which have no basis in 10 CFR 60.                      Again as
!                                          4  Dinesh pointed out earlier, technical positions are not 5  meant to be regulations *.      They provide an approach for 6  meeting the objectives of 10.CFR 60.              Inerefore DOE really 7' has no obligation to take any of the guidance that we have 8  as a regulation.
9            MR. STEINDLER:        What sort of new requirements did 10  DOE allude to when they made their comment?
11            MR. BUCKLEY:        One example that they pointed out 12  was in the technical position it states that all bore holes 13  should be sealed to provide "a factor of safety".                      And they 14  are correct, that is not in the rule.              There is nothing that O                              15  says that they have to have a factor of safety.                      However 16  like we say, it is just guidance.
17            MR. STEINDLER:        Why did you put it in?
18            MR. BUCKLEY:        It was put in, because technical 19  positions are not meant to be regulations.              They are 20  guidance and they provide an approach that DOE can use, an                      j 21  acceptable approach to the staff for meeting the regulations 22  of 10 CFR 60. As Dinesh pointed out earlier, there is a 23  fine line that you must run betwean 5#oviding guidance and                      ;
24  expanding on the regulations.

2            MR. BUCKLEY:    It was not expressed in the 3 comments, so I would not want to address that.
4            MR. MOELLER:    Dr. Gupta.
t                  5            MR. GUPTA:  What we,are talking about here is the 6 design. Even if a performance is not allocated to a seal 7 component, the staff feels that it is prudent on the part of 8 DOE to provide redundancy in the design of all of the 9 system. So that in case that they have been able to 10 evaluate and collect enough data to show demonstrably some 11 performance of certain components but providing redundancy 12 or making sure that you have some margins available in the 13 design. You can never define a factor of safety in any p    14 given case.

15            MR. BUCKLEY:    The State of Nevada provided to 16 significant comments rbgarding Section 3.1 of the technical 17 position which deals with design considerations. The first 18 of Nevada's comments says, "The technical position should 19 assume that seals are important to waste isolation and thus    i 20 should be included on the Q-list."
21            In the second comment, which is slightly 22 inconsistent from the first, tho State of Nevada says that, 23 " DOE should not rely on seals for any contribution to waste 24 isolation."
25            In response to both of these comments on this

( ,)  1 particular topic, the NRC staff would agree more closely 2 with the first comment by the State of Nevada.      Our position 3 is, as Dinesh pointed out earlier, that seals should be 4 assumed to be important to waste isolation and should 5 therefore be put on a Q'-list yntil such time that DOE can 6 show that they are not important to waste isolation.
7          Three significant comments were presented which 8 address site characterization considerations.      And that is 9 Section 3.2 of the technical position.      The first comment is 10 by the State of Nevada. The State of Nevada contends that 11 shaft and ramp locations should be such and can be such that 12 thej eliminate any potential for run-off of surface water 13 into the underground facility.
f (~3  14          The NRC comment to this particular statement is LJ 15 that the NRC cannot dictate to DOE the locations of shafts, 16 and ramps, and bore holes. The location of shafts and ramps 17 must be such that they are consistent with meeting f      18 performance objections of 10 CFR 60.      If they are, the NRC l
19 cannot dictate their locations.
20          The following comments, comments two and three i

Again these comments go back to similar questions 23 which I addressed in the general comments.      DOE states that, 24 " Shaft and ramp locations as well as bore hole locations and 25 the numbers of bore holes should not be included in this

6            Do you expect them,to pay attention to the 7 prescriptions that you have provided on the location of 8 shafts and ramps, even though the subject of the technical 9 position does not really deal with location; it deals with 10                what you do with them after you have drilled a hole and you 11                want to now plug them up.
12                          MR. GUPTA:    Could I address that?
13                          As you stated in the earlier portion of your
()              14                question, the description or the discussion on the location 15                and the number of boreholes has been included in this 16                technical position for' completeness sake.
17                          As far as the basis is concerned, it is basically 18                a reiteration of 10 CFR 60.15.
19                          We have not taken up any new ideas that the                                          j 20                regulations require where and how many boreholes DOE should 21                be using for site characterization.
22                          So it is not really a requirement that has been 23                added in any way to the technical position.        It is basically 24                for completeness sake, a reiteration of what exists in the 25                regulations already.

2              addressing that was it is kind of like what the discussion i
3              the technical review board had about the construction 4              techniques.
5                          Rather than u' sing one technique which would cause 6            expanded damage zone, then trying to compensate for that 7              through some sealing technique, use some technique that 8              avoids that damage so that you do not have to rely on seals 9              to provide any performance.
10                            That was the only indication, connection we had 11                with the shafts and seals.
12                            MR. STEINDLER:    Fine. I appreciate that 13                discussion.
    ,-        14                            I have made the comment that I thought that this 15                technical position does stray on occasion from the specific 16                and somewhat narrow topic of barriers and seals and there 17                may be some advantage of paying attention to that particular 18                criticism.
19                            MS. MOODY:  What you are saying here in your 20                response is simply that NRC is only concernen with 21                performance objectives.      That is what you are saying.
22                            MR. BUCKLEY:    What I am saying is that as long as 23                the DOE meets the performance objectives, NRC Staff cannot 24                dictate to the DOE the locations of shafts and ramps.
25                            Does that answer your question, or is there (N                                          Heritage    Reporting  Corporation t                                                      (202) 628-4888

(,,    1 something else you would lip.e to ask me?                        l l
2            MR. MOELLER:    I thought, though, and I am not sure  i 3 I followed everything, but I thought the location of the        i l
4 shaft and the ramps could very much influence the 5 probability or possibility of, water intruding into the 6 facility.                      .
7            So from that point you have argued in the past 8 that in fact you had asked that the shafts be relocated, the 9 positions be relocated.
10            Now, I guess though, continuing on with what Dr.
11 Steindler said, if the seals are being designed to 12 accommodate any flow that gets down the shaft, then what 13 pertinence does it have?      Or why did you then discuss the
()    14 location of the shafts in the ramp?
15            MR. BUCKLEY:    The locations as discussed in the TP 16 were only put there for the purpose that they may affect 17 either one, the performance of the seals, two, the testing 18 that is required, or to come up with a final seal design, or 19 three, the design of the seal.
20            So if it does not, if the location of the shafts 21 and ramps do not affect one of those three items, then it is 22 not intended to be covered here.
23          As I understood Dr. Steindler's question earlier, 24 I think he was wondering whether or not the NRC Staff was 25 planning on addressing location of shafts and ramps in some D

(}      1 other technical position for some other purpose.
2            Is that -- ?
3          MR. STEINDLER:      No. Almost. But in effect you've 4 got a Section 3.2 entitled site characterization 5 considerations.                    ,
6            You give five poinks that strictly interpreted 7 have very little to do with the barrier performance itself.
8            So I am trying to be a little more narrow in my 9 interpretation of what this technical position should 10 address.
11          And then I look at that comment from, those two I
12 comments from DOE and I sense that they have the same 13 concern I do.
                          ,f g      14          Namely, it is not very obvious whether your
                          \-)
15 technical position paper as currently written would suffer 16 severely if you knocked out that whole section called site        ;
17 character 12ation considerations.
18          MR. GUPTA:    Could I address that, eir?
19          MR. STEINDLER:      My conclusion is that if you took 20 those out, there are five items the rest of the technical 21 position could stand on its own without any serious damage.
22          But that is a viewpoint rather than an obvious          l 23 conclusion.

    )                        I      would be difficult for DOE to demonstrate that seals were 2        lost for the time period for which they are required to            l 3      perfora if they take credit for it.                                  !
4                    MR. STEINDLER:      Right.
5                    MR. GUPTA:    Ahd therefore, it is prudent for DOE 6      to minimize the need for sea,ls.                                    j i
7                    Now, how do they go about doing that?                  l l
8                    To minimize the need for seals you have to 9      minimize the possibility of infiltration of water into the 10      underground repository, and with respect to gaseous outflow, 11      what can be done with respect to any design features that 12        can be handled.
13                    Now, for infiltration there are a certain few 14      things that can be done.
(( )
15                    Like you can locate your openings in a way at 16      -elevations at the ground surface where the possibility of 17      infiltration is less than at some other locations that may 18      be considered for those openings.
19                    So obviously that is a pertinent point, a 20      pertinent position in our view and very germane to the 21      overall technical position on seals.
22                    MR. STEINDLER:      Fine. I don't think it is worth 23      pursuing our discussion.

()          1                My understanding in that this was the subject of 2    an intense discussion among the staff and I think with the 3    advice of General Counsel it was the, we would be better 4    . served to rely on 60.24 which had to od with data to support 5    the license application *, rather than to rely on division of 6    60.140 which is performance confirmation.
7                The reason being is that the intent of performance 8    confirmation in 60,140 was to make data available to the 9    Commission and the Staff at the time of closure.
10                So it is all oriented to providing information at.
L 11    the time of closure to verify all these assumptions, 12    analyses and things that you have based your construction 13_    authorization decision and tian the decision to emplace

MR. MOELLER:      And again that would be laboratory and benchtop work?

13            MR. GUPTA:    Yes. In the site characterization 14  plan they have identified their test program, yes.
15            MS. MOODY:    Thank you.
16            MR. STEINDLEk:      How can there be underground 17  testing if you haven't sunk the exploratory shaft yet?
18            MR. GUPTA:    This is a plan for testing, not the i
19  actual testing, sir.

I 4              The principal item for discussion this afternoon 5  is the following subjech:      the preliminary findings of the 6  Waste Confidence Review Group.                                    I 7              And what we planned to do on this was to have as 8  we agreed at the working group meeting last week to have a 9  summary which I will present of what we heard; and I guess      l 10  everyone was here except Dr. Steindler and herd the detailed 11  half-day review.
12              So I will summarize, and there may even be errors 13  in my summary. But we will then ask Dr. Parry to add to it f;-  14  and then each of you.
(>)
15              And then we want to avail ourselves of the Staff 16  in terms of answering questions that may have developed in 17  the interim and questions that Dr. Steindler in particular 18  has and then we will, once we have done all of that we will      ,
19  go into Executive Session and see if we can prepare some        ]
20  written comments for the Commission on it.
21              Now, I did prepare a two or three or four page 22  summary and that should have been run off?
23              MR. PARRY:  Yes.

l 5      this afternoon.                            ,
6                        Could we pass that.out to them then?
7                        MR. PARRY:    Yes.
8                        MR. MOELLER:      It is the first three pages in this    l 9        item.
10                              While Jack is passing it out I will tell you 11            roughly what I wrote down from last week.                And the other 12            important thing to put on the record and for Dr. Steindler 13            to know was that at the meeting we, for the first time 14            -received a copy of the preliminary draft of the Waste 15            Confidence Review Group's report.
16                              We had not seen it prior to the meeting.        It was  l 17            given to us at the meeting.                Of course they went over it and 18            we in the meantime now have had an opportunity to read it.
19                              okay. In terms of my summary, I would offer the        ;
20            following comments:
21                              First of all, we met for half a day with Robert 22              Banero on April 19 and he reviewed the status with us.
23                                I thought it was a very clearcut presentation.
24                                I asked him how the review group was appointed, i'
l                                            25              how the membership was selected and he said that they were l                                                                                                                                        ,

82 1  selected for their expertise and to assure that all the 2  potentially impacted offices within the Commission were 3  represented.
4                                And he pointed out that each team member had an 5  alternate'and that everybody was heavily involved. And I                                                                                                    ..
6'  think that came out rather clearly in the discussion that it 7  'was really a team effort and everybody had had a chance for 8  input.
9                                He also brought to our attention and reviewed the                                                                                  i 10  existing waste confidence statement and that is the original                                                                                                    l 11  review'was the result of the petition from the NRDC which 12  requested a decision on whether radioactive waste from                                                                                                          j 13  nuclear power plants could be safely disposed of.
        ~
14                                And they suggested that the NRC not. grant any 15  additional operating licenses until a satisfactory finding
          ~
l 16  had been made.
: 17.                              He also pointed out that that original confidence 18  proceeding was done on a specific plant basis, that is, that 19  'it was done for Prairie Island and Vermont Yankee.
20                              As you will see in a few minutes, that is one of                                                                                .l 21  the changes that we want to make that the Staff is proposing 22  be made in the revised statement.                                                                                                                                l 23                              Now, the 1984 findings of the waste confidence                                                                                      !

25                                They concluded that disposal in a repository was Heritage      Reporting                                                Corporation

()
                    ,m 1 feasible, that at least one repository would be available by 2 the year 2007 to 2009, somewhere in ' hat time period.
3 Again, that is where we have a major change in the new l
4 findings.          And that sufficient capacity would be available 5 within 30 years to disp *ose of,all spent fuel and high-level                                        !
6 waste that had been generate,d.
7                  They thirdly concluded that spent fuel can be 8 safely stored for at least 30 years.            They felt that and 9 also concluded that sufficient onsite or offsite capacity 10 for interim storage would be available as needed.            And 11 since, however, this decision involved predictions of what 12 is going to take place in the future, or to occur in the 13 future, they said that every five years they would revisit
(~3  14 their decision and reconfirm it or modify it as necessary.
                  \/
i                      15                  And the schedule, why we have to do our work at 16 this meeting, is that the staff is to submit a proposal to l
17 the Commission by May 12, next month, and the Commission 18 then will decide by May 31 whether it will be published and 19 if they agree to its publication the public will have until l
l                      20 September 1 to comment.
l l                      21                  And then by December 15, the staff will have 22 revised it as appropriate and will be ready to issue the 23 final document.
24                  Now, the key changes as my notes indicated are as 25 follows -- the key changes, that is, how will the new Heritage    Reporting  Corporation
[~}
As                                    (202) 628-4888 l
_ _ - _ - _ _ - _ - - -          - _ _ _ - -                                                                                    )
 
4 84 I              1  decision compare with the old one, what will be the changes:
2            Well, the first one, which I think essentially 3  everybody would agree with, is that the time frame, the year 4- 2007 to 2009, as' Bob Banero said, you know, 2008.plus or 5  minus 1 is totally non-healistic.
6            And so.they propos,e that they say that at least 7  one, that it is their prediction that at least one mined 8  geologic repository will be available within the first 9  quarter of the upcoming 21st Century.
10            And so that certainly is a much wider time span 11  and a more realistic prediction.
12            Then secondly the Staff believes that it will be        j 13  possible that-spent fuel can be stored for up to 100 years.
()            14            Now, we need to call on people like Don Orth for 15  comment on that.      Certainly they are not talking 100 years L
l                            16  under water.      They are' talking dry cask storage the last 17  part of that.
18            But they are saying 40 years would cover the 19  Initial operating license of a typical power plant.      Then if l
20  ycu extend that license for 10, 20, 30 years more, you are f                            21  up to 70 years and then you store it 30 more waiting to get l                            22  it into the repository.
23            So they tried to pick a time frame that gives them 24  the flexibility that they need.
l 25            And then lastly, I should have probably said it in
()                                Heritage      Reporting Corporation (202) 628-4888
 
i 85  1 1 the first one, is that the new confidence statement is 2 written on a generic basis.      They are divorcing it from any 3 specific plants.
4          I am sure no one has any problem with that.
5          Now, to offer *a few more comments that came out of 6 the discussion, Mr. Banero s, aid that it was his opinion that 7 the need for an MRS is now to use his word, moot, quote 8 unquote. And with the development of highly acceptable dry 9 cask, onsite storage systems, simply the need for an MRS 10 almost disappears.
11          Of course we could say unless you consider the MRS 12 as the facility that fixes the waste in a form to put it in 13 a repository, then you might or you do need something but 14 you may not call it an MRS and it certainly is not there to 15 provide interim storage on any longterm basis.
16          Mr. Banero showed us four or five or six slides 17 which I found exceedingly useful.
18          He showed us the Surrey, I guess it is PWR 19 concrete cylinder storage casks that were located out on a 20 concrete platform.
21          And then he showed us the GE dry system which I 22 would call a mausoleum or something like that, in that you 23 move the cask over to this big concrete vault and it is like 24 slipping a casket into the    --
25          MR. VOILAND:    The new home system.

{
,r 3  1          MR. MOELLER:      Yes, the new home system. Thank you                                            I (22                                                                                                                  )
2 Gene. Slipping a casket into the vault.      Instead of dead                                                j 1
3 people you put in dead waste, and shut the door.      But it                                                !
4 looked pretty good to me.
5          Then next the NRC Staff provided the ACNW with a 6 preliminary draft and we all.need to review it.      But I am I
7 sure that Bob was very straightforward with us, Bob Banero.
8 There are no hidden zonkers in the written report.            He told 9 us everything that is in it.
10          Now, I wrote down just some questions that the 11 Committee might want to debate or consider.      And let me go 12 over those and then we will call on Jack for comment and 13 call on any of you for comment.
14          But some questions that I wrote down:
15          One:  What is our confidence that a high-level 16 waste repository can be constructed within the time frame 17 indicated by the NRC Staff?
18          Now of course Bob said that, I think he said and I 19 am sure he said, that his timeline accounts for Yucca 20 Mountain being declared unacceptable and then moving on to 21 somewhere else.
22          The second question:      Will the NRC Staff be able 23 to demonstrate that the facility proposed by DOE will meet 24 the probabilistic standards promulgated by EPA?
25          And that came up this morning and it is going to e,                    Heritage    Reporting Corporation
(_)g                            (202) 628-4888
 
87 l' continue to come up.
i 2            Third:  Need we consider the delays in the l
3  acquisition and analyses of the data needed for site 4  characterization?
5'            As Lincoln sald, I guess I will "long remember" 6  Dr. Lehman's elegant presentation to us a month or two ago 7  on-that. It was one of the best I have heard and it sticks 8  with you.
9            So we need to think about that.
10            Four:  Decommissioning wastes are to be considered 11  separate from this. That was just a key point. That is not 12  a question.
13            Banero stressed that when you are decommissioning 14  a plant of course the fuel has all been removed and you 15  don't mix up decommissioning wastes into this discussion.
16            That, to repeat, is a comment, not a question.
17            The next one:    If orderly onsite dry cask storage 18  is available, the pressures for the repository are              l 19  considerably released.
20            Now, having said that, it is still important to 21' note that Congress will not accept this approach and that is

88 1 you know, it certainly takes the pressure off from the 2 repository. So I guess it is Congress' problem.
3            Marty, you have problems?
4            MR. STEINDLER:    I am a little confused, as usual.
5            The topic is waste confidence rulemaking --
6            MR. MOELLER:    But it includes --
7            MR. STEINDLER:    -- which is originally driven by a 8 Court injunction or Court order.                                ;
9            MR. MOELLER:    Yes.
10          MR. STEINDLER:      If I read the Court order right, 11 you are required to address this in relation to both the 12 time schedule and the license termination.
13          NRC has apparently elected to set aside the time
()                    14 schedule and set aside the license termination issue.
15          Was there any discussion at all during the course 16 of the meeting that the NRC believes they can get away with j                              17 that?
I l                              18          MR. MacDOUGALL:      I would like to suggest that Bob 19 MacDougall, who is the senior person on the Staff, or John, 20 respond to those questions after this introductory talk.
21          MR. STEINDLER:      Okay. Because some of the 22 discussions that I have heard, some of these questions are 23 interesting and probably in the larger sen'se pertinent, but 24 I think seem to be outside of my interpretation of what the 25 driving force for that rulemaking is.

3          MR. MOELLER:  Well, could we go ahead with it now?
4 This is as good as any. Please, go ahead.
5          MR. MacDOUGALL:    I'm Rob MacDougall with the 6 Office of Nuclear Materials pafety and Safeguards,          I am 7 working on the waste confidence review.                  ,

9          MR. MOELLER:    Sure. Go right on up, string on a 10 mike and we will-hear you.                                                j 11          MR. MacDOUGALL:    Well, Dr. Steindler, I think I                i i
12 would open my response by saying that the Commission 13 considered this question at the outset of what became of the
{
14 1984 waste confidence decision.
15          In its original Federal Recister notice in October 16 of 1979, it consciously went beyond the scope of what the 17 Court had ordered, to assess generically the degree of 18 acsurance now available tha* radioactive waste can we safely 19 disposed of -- and you can see it up there on the slide --
20 and determine when such disposal or offsite storage will be 21 available and to determine whether the waste can be safely 22 stored past the expiration of operating licenses until 23 offsite disposal of storage is available.
24          The Commission considered --
25          MR. STEINDLER:    Would you say that is still within I

()            I the framework of what you believe the Court's message to you 2 guys is?
3                    MR. MacDOUGALL:    Well, it was intended to be 4 responsive both to the Court's remand which was focused on a 5 narrower issue of wheth'er there would be disposal by the end 6 of the available -- by the epd of the operating licenses for 7 the two reactors in question.
8                    And then whether the spent fuel, if not, whether 9 the spent fuel could be safely stored onsite.
10                      The context of the reactor licensing proceeding I 11  think, and we have an attorney here who can correct me if I 12  am wrong, limited the scope of the question that the Court 13  remand could deal with.
()              14                      And the Commission decided that the itch the 15  interested public really wanted scratched was the question 16  of when disposal would'be available and in effect the issues 17  laid out in the waste confidence Federal Reaister notice.
18                      MR. STEINDLER:    Your comment then is that that l                                19  statement that is currently up on the board not only include 20  what the Court remanded to you folks but also the larger 21  question that the then Commission believed to be of interest 22  to the public?
23                      MR. MacDOUGALL:    Yes.
24                      MR. STEINDLER:  But it included both?

8                      Let me see. Finishing up my comment, and I am not 9 sure all of these are questions:
10                      They pointed out to us that Yucca Mountain 11 protably will not be able to hold as much waste as Congress 12 has set as the limit for the first repository.
13                      So another question is:          Can spent fuel be held 14 safely for 100 years?                Again, as I say, we have to look to 15 Gene Voiland and Don Orth for that.
16                      Then last - ' and I thought this was probably one 17 of our key comments, even though I didn't get to it until 18 last, and that was:              Has the NRC Staff, in our opinion, 19 considered a sufficient number of scenarios in looking 20 toward this decision, you know the various pathways that 21 activities may actually follow, have they looked at enough 22 of them?
23                      And this may need decision on our part.
24                      And so with that, Jack, could you offer any 25 comments you may have?

12                                          It turned out it reflected very well, as Bob 13                              Banero presented to us, excellent.            And I will just read a 14                            -few of these comments.
?\
\2                                      15                                          I said that the document is well and clearly 16                              written. It reviews the findings of the 1984 waste 17                              confidence deliberations in a systematic manner and in the 18                                light of technical advances and legislative changes, 19                              particularly the effects of the 1987 amendments to the 20                              Nuclear Wasts Policy Act.
21                                          In general, the review group found no reason to 22                              abandon the conclusions previously reached that successful 23                              disposal of spent nuclear fuel and high-level waste derived 24                              therefrom could be accomplished and that extended interim 25                                storage until the availability of the disposal repository Heritage      Reporting    Corporation O                                                                                                      (202) 628-4888
 
9 94 1  posed no significant additional risk to public health and 2  safety.
3              Perhaps the most significant changes in the 4  rationale for the relatively few changes in wording of the 5  findings were one, the recognition that the earlier 6  congressionally-established timetable was no longer, if it 7  ever was, attainable, and that it was prudent to project 8  availability of the repository to some time in the first 9  quarter of the 21st Century; and two, that the actual 10  demonstrated accomplishment of dry storage of aged 11  commercial reactor fuel at reactor sites gave added                                                                                          ,
1 12  confidence in the successful, longterm storage of spent fuel 13  in the event of a long delay in commissioning the disposal 14  facility.
15              Such a delay could conceivably occur if the 16  congressional decree to quality sites successively rather 17  than in parallel turned out to have been a bad decision.
18            . Failure of the Yucca Mountain site to qualify 19  could perhaps result in a 25 year delay in availability.
i 20              The principal conclusion was that the various 21  changes could have profound effect on the timing of 22  beneficial use of the repository, but no real effect on the 23  confidence that the facility could and would ultimately be 24  operative.
25              The Review Group emphasized it was far better to l

3                  Then I had a number of specific comments. And 4    they are just that.
5                  And they were*put dpwn here really for our Staff 6    to use if they felt they werp of significance.      And I am not .
7    going to address many of those.
8                  MR. MOELLER:  Well, hit the highlichts. And let  I 9    me just say for the purpose of the record that we do have 10            the memo from Gene Voiland and it will certainly be made 11            available to the Staff.
l 12                          MR. STEINDLER:    That is correct.                  j 13                          MR. MTELLER:  Yes. I would suggest that it be
              ~T        14            made available to the Staff because it points out typos and (G
15            so forth and'that way we get the benefit of your review.
16                          So hit the highlights.
17                          MR. VOILAND:    I think the one comment that I felt 18            may be worthwhile is considering the capacity of the 19            repository, because that came up time and time again.
20                          And the capacity of the repository is stated in 21            terms of metric tons of heavy metal or initial heavy metal, 22            specifically with a limit of 70,000df for the initial 23            repository.
24                          This may make sense from a political perspective, 25            but it certainly does not from a technical point of view.

p                                                                                              .
96 1                  Technical capacity will be dictated by the. volume O                        2-        of the waste packages, which could be affected by rod t                                    3      ' consolidation, thermal output of the waste and the heat 4        dissipation characteristics of the site.
5                  But the delay *in availability of the disposal 6        facility, theoretically the beat output of the fuel will be 7'        reduced and a more dense storage rate could be accommodated.
8                  Also, the technology of rod consolidation could 9        improve.
L                                        10                  A corollary of this is the undesirability of 11        transferring green fuel to the repository as the higher heat i
12        output would reduce the capacity                              because of thermal 13        dissipation considerations.
14                  Another consideration is the specific effect of 15        higher fuel burnup in the reactor.
16                  One effect is the reduction in the number of fuel 17        assemblies requiring disposition.                              However each assembly 18        does contain a greater amount of radioactive material.1 19                  This effect only appears after a number of years 20        when the short-lived radionuclides? are decayed away.
21                  A long term effect is the change in the nature and 22        quantity of actinide elements for the same amount of power 23        generated by the extended life fuel.
24                  If it has not been done it would seem reasonable 25        to evaluate the technical capacity as a function of fuel I

i 12            MR. MOELLER:    That would be interesting.
13            Jack, you had a comment?
() 14            MR. PARRY:  Yes. I wanted to mention, and I think 15  it came out during the discussion about at least for example 16  Calvert Cliffs where they are going into dry cask storage.
17            The intent there is that they will dry cask 18  storage their oldest fuel and that it will be retained in 19  dry cask storage and fuel will go out of the pools into the 20  repository. So really newer or not the oldest fuel.
21            So I think your point about heat loading is one to 22  which the Staff may wish to address itself.
23            MR. VOILAND:    I had a comment about that.
24            Bob mentioned that the DOE policy was to move 25 -coalesced fuel. And I guess my reaction is that what will

2 that relieved before you go start going back as Jack has 3 suggested here into stored fuels.
4                  But I think they may have to revisit that policy 5 decision.                                ,
6                  There just a couple of items having to do with the 7 curves that were presented showing the amount of fuel that 8 would be put in dry storage, assuming their considerations 9 are correct.
10                  It turns out to be quite a bit.      It turns out to 11 be 500 tons of dry storage for each reactor.
12                  All I did there was take a look at the quantities 13 of fuel which their curves indicated were in dry storage, 14 and did the division by year, et cetera.
Os            15                  So that might be something to look at.
16                'There is quite a bit of money associated with that t
17 and I thought that the consequences of extended delay in the 18 availability of the repository could benefit from a 19 reasonably detailed impact analysis.
20                  MR. MOELLER:      Now, who should do that?  Is that l
21 something DOE, you are suggesting DOE do it?              Is this 22 something the NRC Staff would want to do?

6                                    And it would just seem to me that if DOE for 7                            example changes its scheduling as a result of this -- as a 8                          matter of fact it seemed to me that the presentation was a 9                          good basis for some kind of a schedule -- then it would be 10                                  just reasonable to evaluate what that impact would be.            ;

21 happens if DOE screwed up their schedule.
22                    MR. MOELLER:    Excuse me. This must have been 23 calculated to some degree because in the licensing support 24 system, which we are going to review tomorrow, whenever it 25 is, it is $200 million a year.              Someone has already I

7            I might mention that you will be shortly receiving 8 an article by Luther Carter that was provided by Dr. Moody.
9            In that article he goes through an extended review 10 of the history of high-level waste management in general and 11 then makes what I thought was a rather cogent suggestion 12 about co-location of an MRS facility that could be sited            ;
l 13 where you think you might have the repository so that you 14 could have the storage capacity there.                              i
                  }
15            Of course that would mean change in at least two 16 aspects of the Federal' law which one prevents co-location 17 and the other limits the capacity of the reposi&ory to 18 15,000 metric tons, besides other problems with timing and          i 19 so forth.
20            MR. STEINDLER:      Limits the capacity of the MRS.
21            MR. PARRY:    15,000 tons.

O          15          And I do know from my bit of involvement .ayself 16 with respect to the SALT program that that is also, that is 17 a major difficult issue.
18          So-there is another side totally to this question.
19 That is, keeping the waste at the place where the power 20 plant is has with it a sort of a cushion with respect to all 21 of the issues related to transportation.

'h    1              I really have a question as to whether that is 2  going to speed up the licensing process.
3              The reason I say that is that if you read 10 CFR.2      l 4  as it stands today it really is a pretty good process.        If 5  it is followed, I think'it is, efficient and it won't get you 6  in trouble,                      ,
7              On the other hand, what has happened is that it 8  has been abused and the NRC has allowed it to be abused, in 9  my judgment, and I can give you chapter and verse on that.
10              And I think, if LSS appears to be good, it is 11  going to have to be administered carefully.        Otherwise, it  l 12  will be abused.
13              These regulations are intended for people to
    .14  . fulfill. If you find somebody that wants simply to cause 15- delay and obfuscate Congress and all the rest, they will 16  find a way to do it.
17              So this probably should be in abeyance.
18              And I have kind of the same feelings about
    ~19  negotiated rulemaking, since I don't understand how that 20  works well enough.
21              Again, AEC and the NRC have said that the purpose 22  of the regulation is to protect the health and safety of 23  people. There might be a risk that some of that could be 24  abrogated by negotiated rulemaking.        I just feel 25  uncomfortable with that.        It might be the best thing since O                        erie se    aegerti=9  cerrer tie-(202) 628-4888                        j l

4                            In finding I guess number one, in finding number 5            one, is there a distinction made by the Staff on whether or 6            not a repository could be accomplished versus whether a 7            repository could be accomplished in the particular time 8            frame?

12                            IR. STEINDLER:      Okay. You make that distinction 13            consciously.          That is why you bring in the first quarter of p_      14            the next century?

21                            MR. STEINDLER:      Is it the contention of this group 22            that the number of options reviewed by the Staff to make 23            this generic determination that somewhere in this world you l

3              (Laughter) 4              MR. STEINDLER:      That is not, I think, what the 5  Court had in mind.                            ,
L                          6              Now, I am neither ,a lawyer nor do I claim'having                                j 7  read the decision. But just on a pure rationality basis it 8  seems to me that somebody is looking for some reasonable 9  assurance.
10              MR. MOELLER:    Maybe, is there a lawyer who can                              -j 11  comment on it?
12              MR. MacDOUGALL:      I can quickly summarize, and 13  quickly be corrected ~if I am inaccurate.
14              MR. MOELLER:    Okay.
O                15              MR. MacDOUGALL:      I guess to begin with the Court 16  did not impose a Sword'of Damocles over the licensing of 17  these reactors. It let the NRC-approved license amendment 18  stand, and focused principally on the question of what 19  happens after the operating license expires.                                              n 20              And so the 2007-2009 date came up pretty much as a 21  juridical artifact by virtue of the fact that that was when 22  these two operating licenses were due to expire.
23              And since the scope of the Court's ruling was 24  within the context of the license amendments at issue, it 25  really did not deal with the larger questions that the Heritage    Reporting                    Corporation f^)
(-                                              (202) 628-4888 1
 
112 gx    1 Commission felt they were probably trying to get at, having d      2 to do with the safety of disposal and when it would be 3 available, regardless of the expiration of the OLs of the 4 reactors in question.
5          I'm not sure that that's --
6          MR. STEINDLER:  Well, no, that's fine, but let me 1.
L        7 play the devil's advocate and point out that what have you 8 done?
9          You have taken the expiration of the license and 10 said well, we don't think the repository is going to be 11 ready in the -year 2008 plus or minus one but we will push 12 the repository out to what we think is a more realistic 13 time, and then further we will declare that we can store the                      l s  14 fuel safely until that period of time.
15          Let me take you 15 years from now to the similar 16 hearing in front of a similar group going through the 17 similar process, having done it now three or four times.                          ,
18          I can envision the then Advisory Committee on 19 Nuclear Waste hearing from your counterpart or you saying 20 well, yes, the DOE repository is going to be late so we are 21 out in the year 2065, and oh by the way we think we can 22 store fuel safely for 200 years.
23          That is not an unnatural sequence, but I have a 24 hunch that you might get challenged on it if that is the 25 mode of proceeding.

8                      MS. CYR:    I am Karen Cyr. I am with the General
                                                                                  ~
I 9            Counsel's office.
10                        If the Court recognized that what they were 11              looking for from the Commission, I mean you are looking at 12              an environmental assessment in the nature of a prediction, 13              recognize that you are looking some years down the pike at 14              the time that'they remanded that decision to the Commission, 15            _meking some prediction whether they had reasonable i
: h.                                    16              confidence at the time' that the license expired that it 1
17              would either be disposed of or you could safely dispose of 18              it until at such time as that happened.
19                        And the Commission made a determination that it 20              had such reasonable assurance, and it had a sufficiently 21              developed basis for reaching that conclusion, that in fact l
22              it had reasonable assurance, that you could store it while 23              you needed it, while it was onsite, and at that time we felt 24              that'there was reasonable assurance based on the information 25              we had available to us at that time that the repository Heritage Reporting      Corporation i                                                                              (202) 628-4888 o                                                                                                                    1

2 be.                                                                    ;
3            So that we were looking at the environmental 4 consequences of letting the fuel continue to be generated 5 and the safety consequences of letting the fuel continue to 6 be generated and we reached ,a conclusion that we had 7 reasonable confidence that those were taken care of.
8            And I think this decision really follows on from 9 that. We are five years further down the pike. There have 10 been some good things and some bad thing happen in terms of 11 how DOE is approaching the program, but we've got more 12 information and we are reassessing that decision now and we 13 are still looking 20, 25 years down the pike. So I mean it
  ,,  14 is still very much in the nature of a prediction.
15            But that was, the Court recognized that at the 16 time that they remanded it to us. So that is what we are 17 doing, everything that we are doing because we are looking 18 so far along.
19            And so I don't think it is anything improper in 20 recognizing that that is what we are doing. We are making a 21 prediction based on the information we have available to us.
22            And we have a little better information today than 23 we had five years ago and so you ought to be more precise or 24 held perhaps a little more accountable than you were but you 25 are still looking a fairly long ways out into the future in

3 points.
4                                    But you know, one of the ones that strikes me is 5 that~we have had a little morp'information, therefore we are 6 trying.to be a little more precise, when in fact we have 7 loosened.up the thing.
8                                    We have said in'effect our backward look -- we 9 have gotten smarter I guess -- our backward look of 2007 to 10-          2009 was absurdly narrow.-We have moved this thing out now .
11          to a range.
12                                              You know, I am not suggesting that I have either a-                                                                                l 13          better answer, which I do not, because I think you have done                                                                                                        -

16                                              I am just trying to see whether or not there is 17          something that we should be looking at that is likely to get

20                                                MR. MOELLER:          We have a couple other comments.
21            But let me ask a question.
22                                                Who is it that decides whether your conclusions 23            are acceptable?                            Not you but the NRC's waste confidence 24            statement.

2                MS. CYR:  The Commission obviously in the first 3    instance makes the decision based-on the information that it 4    has.
5                MR. MOELLER: 'Okay.,
6                MS. CYR:  And it is going to put out a proposed 7    decision which will be subject to public comment and we will 8    revise it as necessary to reflect those public comments, and 9    the Commission will again revisit it to determine, they are 10    really going to bc putting out a preliminary decision, 11  presuming they go along with what we send down to them on 12  May 12, that this is a basis for continuing to find 13    reasonable confidence.      And then, presuming that 14  determination continues, then in December.
15                Now, at the time that we make that decision in 16  December, if someone thinks that we have not established an 17    adequate ba-is for our determination, someone could take us 18  to court and challenge that decision.                      .
19                MR. STEINDLER:      So you are challengeable o this    =j 20    rulemaking?

7            In other words, are the regulations as presently 8 presumed demonstrable?      Is that what 30ur finding concludes?
9            MS.

15                  I noticed in the most recent news that I got that 16      there was a big hassle'about a contractor.
17                  I presume that is for the construction and 18      operation of the site?
19                  MR. PARRY:    No, not necessarily. That is an 20      integrating contractor.      I'm not sure it is total impact.
21      We do have a DOE representative here.        You might want to 22      discuss it with him privately.      But that contract has more 23      to do with the development of the license applications.

l 5 and I am wondering if the group that has brought this l

8          I look at the statements regarding the Staff 9 acknowledges that it is possible to spend fuel, maybe stored 10 up to 100 years, 11          If one takes the devil's advocate role, I wonder 12 if this isn't just preparing the public for the fact that 13 the next five years this is going to be extended even more
(~  14 and is the Commission opening itself up to that kind of V) 15 concern and criticism by cushioning the public into the fact 16 that we can store this' for 100 or as someone said 200 years?
17          And I wonder if the staff that prepared this would 18 look ahead in their crystal ball on the basis of what is 19 onstream now as to what might happen in the next five years?

22          MS. MOODY:    Excuse me a second.

4 make it 150 years later.                                                            l 5          MR. MacDOUGALL:    To, answer your overall question, 6 Dr. Hinze, we would hope that our proposed revised finding 7 would cover the contingencies because our effort was to try 8 to come up with a sufficiently conservative estimate of what 9 is likely to happen over the reasonable foreseeable future 10 such that if for example the Yucca Mountain site did prove 11 to be unsuitable by DOE in DOE's judgment that the program 12 could still recover itself and progross from restarting or i
13 beginning from a new piece of paper on site screening to the
(} 14 actual operation of a repository within the first quarter of 15 the 21st Century.
16          The other point I think we might bear keeping in 17 mind concerning the 100 year storage is that it really 18 represents a 30 year increase in the existing Commission 19 expectation about the safety of storage, to cover the                              !
20 furthest known extent of license renewals.
21          MR. HINZE:    That is excellent.

d 6  realistically are looking at.not only what potentiallyson a                            '
7  shall we say pessimistic basis given as Gene Voiland noted 8  here that instead of three in parallel we have'one 9  repository and basically you are operating now in a 10,  potentially. serious mode and basically a more or less 11    pessimistic assumption was made that potentially'you might 12    not, the first repository might not be it.
13                  But beyond that we are also seeing that we seem
(}                                  14    likely at this point to get, we are already seeing an 15    extension of reactor licenses to full 40 years, it-seems                          j
                                                                      ~
16    like many of them are going that way.          And beyond that, 17    renewal of licenses,.as Dr. Moeller noted, up to perhaps 20, 18    30 years.
19-                So it -would be raore or less disingenuous of the 20    Staff to ignore these factors and come out with a view that 21-  well, we are not going to see this one, when I think we

MacDOUGALL:    I think another thing that might 2                          be helpful to bear in mind is that with the enactment of the 3                          Nuclear Waste Policy Amendments Act in 1987 and the 4                          direction to. characterize only one site for now, it really e                        5                          changed fundamentally the basis for our approach to this 6                          question because we could no. longer assume that there would 7                          be readily available alternatives to the site and that 8                          preferred site is not -- I mean, that as a regulatory agency 9                          we would not want ta) have our confidence rest on the 10                          suitability of a site that had not yet been subjected to a 11                          licensing proceeding.
                      '12                                    And so we felt that for our own sort of regulatory 13                          integrity that we had to assume conservatively that Yucca
(}        14                          Mountain would not prove out.
15                                    MS. MOODY:  I think that is one point I was going 16                          to make. When I read the whole thing in detail I was 17                          impressed with the fact that I think you were more in terms 18                          of projection of possibility that you did do a pretty good 19                          coverage just simply because I agree with you 100 percent 20                          that when we went down from three to one site that really is 21                          a completely different game and completely different set of 22                          possibilities than you had with you could go through the 23                          detailed characterization of three sites.
24                                    It is a completely new game. Completely different 25                          game than what we had been operating on for quite a long

2              FR. MOELLER:      Back on scenarios, what are the 3D  principle scenarios you are considering?
4              We have heard a~ couple. One would be that Yucca      i 5  ~ Mountain works out and *everybpdy is happy.
                                                                                          ^
6              Two is that it' fails and. fails to meet the 7  requirements:and so.you start a second'one but you are 81  assuming there the second one works.
9              Now, if the second one doesn't work then your 10  schedule is all off.
11              What other -- maybe those are all the scenarios 12  you need?    Is'that it?    I mean what else is there,. from the 13  best to the worst?
14              MR. MacDOUGALL:      One other possibility is that if
  .O'                        15  the White House gets around to appointing a negotiator there 16  is that avenue for.another site.
17              MR. MOELLER:      Yes.
18 MR. MacDOUGALL:- So that the effort to find a-19  second repository could begin possibly before the 2007-2010 20  time frame.
21              MR. MOELLER:      In fact that is a very good point to 22  make. That could be extremely helpful.
23              MR. VOILAND:      That site has to be qualified just  l 24  like any other site, i
25              MR. MacDOUGALL:      Exactly. Yes.                    !

18                  MR. MacDOUGALL:          Yes, I think it does represent --
19                  MR. HINZE:      And that is the worst case scenario.
20                  MR. MacDOUGALL:          It assumes renewal of licenses 21        for a substantial portion of the reactors which gives you a 22        different curve than DOE projections which do not make that 23        assumption.

19              MR. ORTH:  If I am going to make general comments, 20  I could start with what amounts to Page 8 on this draft 21  where it talks about the EPA standards which we have already 22  touched on a couple of times.
23              But there is a, the crux of the matter here was 24  that EPA has been, was remanded in July 1987 to start 25  promulgating some new rules.

3            MR. MOELLER:      Thank you.
4            MR. ORTH:    Small print 8.
5            The second pabagraph there notes that it was July 6  1987 that the Court old EPA to get back and get some more 7  standards.
8            And they have been working along since then 9  presumably, and in cooperation with NRC.
10            Further down it notes that NRC believes it can 11  establish deterministic requirements not dependent upon i
12  probabilities to assure that DOE can do things.
13            And finally down on the next paragraph, maybe
    -                14  grounds for concerned revised standards will be expressed in 15  a way that could make it difficult or even impossible to 16  evaluate compliance with probabilistic EPA requirements.
17            'To avoid this outcome the Staff will work closely 18  with EPA during its development of proposed revision to the 19  remanded standards.
20            The NRC Staff is confident that EPA will not 21  promulgate standards for which compliance cannot be 22  evaluated.
23            I think this is challengeable on the basis that 24  EPA frequently has continued on many fields, generated 25  standards on which it is almost impossible to evaluate

5            But the point *being,that this is now middle of 6 1989, two years later after EPA was supposed to do 7 something.
8            Do we have any idea whatsoever when EPA is going 9 to get on with it, first of all.
10            Second, is NRC really actively working with EPA to 11 develop these standards?
12            MR. MacDOUGALL:        The answer to your first 13 question, to the best of my knowledge I think the current
(}                              14 projection is early 1990 for a proposed standard and the 15 answer to the second is yes, we are actively wor'cing with          I 16 EPA.
17            I am not the best person to give you the 18 particulars on exactly what we are doing, though.          If you i
19 like I can provide you some more information.
20            MR. MOELLER:        We had a report on that which I read 21 prior to coming to this meeting and it said that EPA had 22 informed NRC at one of their recent meetings, and indeed 23 they are meeting, that the final standards are not, EPA does        j 24 not anticipate that the final standards will be much 25 different from what exists now.

3          MR.

11                        MR. PARRY:          Actually PNL I do not think is 12 actually doing anything on that.. I think that the 13 assistance to West Valley came~from Savannah River.

8            Gene has already talked about that particular 9 issue. I think that the conclusion is a little broader.
10 Cooperation showed that consensus was ctill possible on 11 important repository licensing.          I think that it is too l
12 broad a conclusion. And again it is that same issue that 13 the agreement was reached between people who were not
        ,s  14 subject to regulation and not with some of the people who                                                    j k) 15 had to worry about it.      So that is hardly a consensus.                                              It l

7              MR.

7                    MS. MOODY:            That is correct.
8                    MR. MACDOUGALL:              A fair point and well taken.
9                    MR. ORTH:            I will turn it over to somebody else at 10  this point.
11                ' MR . MOELLER:              Well, on page two at the top, and I 12  know that I have asked this before, but I still do not 13  understand it.                    It of course begins at the bottom of page
()  14  one but it says on the top of page two, the third line, "No 15  discussion of any environmental impact of spent fuel storage 16  is required for the period following expiration of the 17  license or amendment applied for."
18                    Now if you apply for spent fuel storage before 19  your plant's license is over, then you du have to file an 20  environmental impact statement?
l 21                    MR. MACDOUGALL:              Well, the purpose of the waste 22  confidence proceeding was to assess generically among other l
23  things whether the fuel could be safely stored past the                                          ,
i            24  expiration of the operating license. And on the basis of l            25  this generic proceeding, the Commission concluded that it 1

4 134    ]
()                                    1 could safely be stored.      And so as a result of this generic 2 finding, individual applicants for licensing amendments for 3 storage no. longer need to address the question of 4 post-operational safety of storage or environmental. impact 5 of storage, because the' generic proceeding takes care of it.
6            So it was really ap' amendment to the existing                                                              l 7 rules on preparation of environmental impact statements to 8 acknowledge that we have done a generic proceeding on the 9 storage question.
10            MR. MOELLER:    All right.                                            That helps.            Now I am 11 sure that this is covered, and perhaps'again we have asked 12 it before. The nuclear power plant, the utility, is license 13 operated. So it is now shut down and they remove the fuel
(}                                    14 from the core, but for decades thereafter there is going to 15 be dry cask storage on site.
16            So what does'that do then to the utility, you 17 certainly cannot just mothball that and walk away or can 18 you?
19            MR. ROBERTS:    What is happening and what has 20 happened is for example the fuel is continued to be stored 21 in the reactor pool and so forth.                                        Whether or not you have 22 on site dry storage, you will have what is called a 23 possession, and I do not know if that is a legal term as 24 yet, but a possession only Part 50 license where your 25 Part 50 license is restricted basically to the storage of

1                1 that fuel in the pool.        And you would also have an existing 2 Part 72 license in conjunction with that for the storing of 3 fuel in dry storage on the site if there was excess fuel 4 outside of the reactor base.
5          MR. MOELLER: 'And the utility is still going to be 6 responsible until all of tha,t fuel is removed and the site 7 16 restored?
8          MR. ROBERTS:        Yes, that was the point of some of 9 our findings.
10          MR. MOELLER:        I think that we want to ask any more 11 questions that we have and then we will take a break, and 12 then we will go into executive session to figure out what we                              I 13 are going to say. But let's hear any more questions that we
(}              14 have and any more comments that anyone has.
15          MR. HINTZE:      I have a brief question that shows my
;                16 ignorance, but what happens if a utility goes bankrupt and 17 we have all of this waste sittizg in dry storage, what 18 provisions are then available to us?
19          MR. ROBERTS:        Actually I think that is addressed 20 in one of the findings where we reference the section in 21 there earlier. Under the Atomic Energy Act, the Commission 22 has the power basically to take over.            I forget which l                23 finding.
24          MR. MACDOUGALL:          I know that we covered the 25 question of bankruptcy in our discussion of Finding 2 if a I

1  reactor does go bankrupt.      We found confidence that using 2'
        '2  funds from the nuclear waste fund _ established by the Waste 3  Policy Act that DOE would be able to handle the management 4  of the fuel until a repository were available.        We are 5  really talking about thb time,before DOE takes title to the 6  fuel under a contract with e,ach of the reactors.        So while 7  we do have the authority to require that the fuel be managed-8  safely by some o.ner entity than the licensee if it comes to 9  that, I think that we are' fairly confident that it will not' 10  come to that. That DOE will take over and have the will and 11  wherewithal to do the job.
12'            MR. HINTZE:  Thank you.
13              MR. MOELLER:    One other question. I have read
()    14  this and I do not remember.        When the Commission considered 15  this in 1984, was the vote unanimous and w9re there added 16  remarks by any of the Commissioners and what were those?
17              MR. STEINDLER:    There was I think an interesting 18  remark by Gilinsky.
19              MR. MOELLER:    Yes, I thought so. I would like to 20  be refreshed on what Gilinsky's remarks were.
21              MR. MACDOUGALL:    We could get you those. They are 22  in your handout. I do not think that there were any 23  separate dissenting or concurring opinions in the Federal 24  Register notice of 1984.      But the deliberations of the          i l
l      25  Commission leading up to the decision itself probably              I i

: 4. that there were separate from Chairman Paladino,                                              .
5  Commissioners Aselstein', Gilinsky, and Ahern.        So there were                          l 6  quite a few.                      .
7            MR. MACDOUGALL:        That was the 1983 proposed                                  .
I 8  decision.
9            MR. MOELLER:        Okay. That is not the final. So 10  supposedly, some of those were resolved.
11            MR. MACDOUGALL:        We will get you a copy of the 12  1983 proposed decision.
13            MR. PARRY:    Rob, you provided me a' copy with that 14  previously.

15            MR .~ STEINDLER:      I did not get a chance to read the 16  full document.
17            Did you address the issue of the requirement for

                                                      . PRAs, the possible requirement for PRA laid upon you folks 19  by EPA, and whether or not it is a doable issue?
20            MR. MACDOUGALL:        Yes.
21            MR. STEINDLER:        You did, okay.
22            MR. MACDOUGALL:        That was one of the things that 23  we spoke about a few minutes ago on page eight concerning                                    i 24  EPA's probabilistic standards.

9    With that, I think that I will declare the formal portion of 10    our meeting this afternoon'to be recessed.              We will take a 11    break and then we will go into executive session first to-12    try to solidify and summarize what our opinions are and our 13    comments are on this waste confidence proceeding.                                Then when
(}  14 15 we finish that, we will have available a first real rough
                                        ~
draft of proposed comments on this morning's discussion.
16    And then that should wrap up today.            And the executive-17    session will not be recorded, but it will be open to the 18    public.

f E                                      Draft:  D. W. Moeller f                                        LET223 -- 4/22/89 l
 
==SUMMARY==
OF DISCUSSION ON WASTE CONFIDENCE PROCEEDINGS
: 1. At a meeting of an ACNW Working Group, held on April 19, 1989, Mr. Robert Bernero, Director, Division of NHSS, reviewed the current status of this matter.
: 2. NRC team members, ch 5en to review this topic, were selected for their expertise and to assure that all affected Offices were represented. Each team member had an alternate and all were heavily involved.
: 3. The origin of the eriginal review was a petition from the NRDC which requested a decision on whether radioactive wastes from nuclear power plants can be safely disposed of, and that the NRC not          !
grant any additional operating licenses until a satisfactory finding could be made.
Note:  The original petition was based on challenges to two plants that had requested to expand their spent fuel storage capacity -- Prairie Island and Vermont Yankee.
The 1984 findings of the Waste Confidence review were:
: 94.        a. Disposal in a repository is feasible;
: b. At least one repository will be available by 2007 - 2009;  and that sufficient capacity will be available within 30                          1 years to dispose of all spent fuel and HLW generated;
: c. Spent fuel can be safely stored for at least 30 years;
: d. Sufficient onsite or offsite capacity can be made available as needed;
: e. Because these decisions were made in the form of a prediction, the NRC promised to re-evaluate the situation every 5 years.
: 5. The schedule for the current review calls for:
: a. NRC Staff to submit a proposal to the Commission on May 12, 1989;
: b. Commission will decide on publication by May 31, 1989;
 
['                  c. Public Commerits until September 1, 1989;
: d. Final Decision to be issued by December 15, 1989.
I
: 6. Changes likely to be made in the new decision, versus the old one:
: a. Instead of citing a specific time frame      (2007 - 2009),
they plan to say that at least one mined geologic      l repository will be available within the first quarter of the 21st century;
: b. The Staff acknowledges that it is possible that spent f uel may have to be stored f or up to 100 years --
40 years for the initial operating license for a nuclear power plant, plus 30 year renewal of license for extended operation, plus 30 years waiting for repository capacity;                        >
: c. The Staf f is writing the new decision on a graeric basis. It will no longer be tied into Prairie        ;
Island and Vermont Yankee.
: 7. Another interesting observation of the NRC Staff, as a result of this assessment, is that the need for the MRS is moot. With the            i f '~3    development of highly acceptable dry-cask on-site storage systems, l    /    the need for an MRS becomes less and less.
Q ,)
: 8. The NRC Staff provided the ACNW at the Working Group meeting a copy of a preliminary draft of the Waste Confidence Review Groups
              " final" report.        This needs to be reviewed and evaluated by the    .
ACNW members and consultants and a report written on the matter at this meeting.
: 9. Items for the ACNW to consider include:
: a. What is our confidence that a HLW repository can be constructed within the time frame indicated by the NRC Staff?
: b. Will the NRC Staff be able to demonstrate that the  facility proposed by DOE will meet the probabilistic standards promulgated by EPA?
: c. Need we also consider the delays in the acquisition and analyses of the data needed for site characterization?
: d. Decommissioning wastes are to be considered separate from this. The fuel will already have been removed from a plant being decommissioned.
W
: e. If orderly on-site dry cask storage is available, the pressures for the repository are considerably reduced.
However, it is important to note that Congress will not l
l s
 
f
_. '                                                  accept this approach. That is why they have been hesitant on the MRS. They want the repository built and in operation,
: f. Yucca Mountain will probably not be'able to hold at much as the limit for the first repository (70,000 MTHl
: g. Can spent fuel be held safely for 100 years, as
[*
indicated (assumed) by the NRC Staff?
i
: h. Has the scenarios  inNRC Staff considered evaluating various pathways      a sufficient                    thatnumber o. j.
this mat f                                                                                                                                              !
might follows?    This may need some discussion.

WEST VALLEY DEMONSTRATION PROJECT
: 1. During it b .1xth n.eeting, January 23 - 24, 1989, the ACNW met with representatives from the U. S. DOE, its contractors, and the State of New York Energy Research and Development Authority for a review vf the West Valley Demonstration Project.
: 2. I t-m:. discosued included the procedures that have been developed and are being applied in solidifying decontaminated supernatant low-level warteu and testing the melter for vitrification of the HLWs.
: 3. Th. prucedureu being applied at West Valley include passing the      ,
sun inatant through ion exchange media to remove the bulk of the        l dicuolved radionuclides, and then solidifying the decontaminated papernatant for disponal ac a LLW.      Although this approach appears reasonable, it does raise what has been a basic question as to whether such an approach is acceptable. Some may say that it means p_q                    redocing what wac. a HLW to a LLW.
I t                i J                                                                            ,
xm-            '
At Wect Valley, the resinc on which the radionuclides (primarily Cu-137) are being removed from the supernatant, and the sludge in the bottom of the waste storage tanks will be solidified      !
and handled a; a HLW.      In essence, this results in a fractionation of what were origina}}y HLWs with a major portion of the radionuclides being concentrated in a solidified HLW fraction.
: 4. 1.1though the program appears to be appropriately focused and the  i results are favorable, we noted several areas in need of attention:
: a. Acceptance criteria for the vitrified HLW, including the enumeration of testing procedures                  .
      ;                            to indicate conformance with these criteria, need to be identified by DOE for the waste producers, and need to be reviewed by the NRC to determine if they are acceptable;
: b. Public health and safety criteria for the facilities and land areas being decontaminated and decommissioned as part of this project need to be established.
  #                        5. Other questions that should be considered in the evaluation of this situation include:
1
 
    't              , _
e,
\.      ,
: u. Whether there are mixed wastes at West Valley now and, if not, could the above procedures lead to the development of such wastes?
: b. While the DOE and NRC appear to be demanding that careful criteria be developed for characterizing solidi-f led HLW:., similar criteria do not appear to be required for spent fuel -- which will also be placed in a HLW repository. Is there a justification for this uit uation?
i
: c. perhapu the ACNW and/or the Commission should request that the NPC Staff outline the approaches that were used in approving the waste disposal procedures currently underway at Savannah River and We ;. L Valley. Similar questions pertain to the watte. currently in storage at Hanford.
: d. Perhapu it is also time, once again, to consider developing a definition for HLWs. This might be ut.e f ul in 2eviewing similar tasks in the future.
C. The ACNW still plans to visit the West valley Site sometime thi
        ,q                                          summer.

Although thic ie on1y in the discussion stages, we have been evploring the potcibility of requesting that the NRC Staff ask DOE t o devel op c Scoping Study PRA for the Yucca Mountain facility.                        We note that t h t, ha.m M ready had an Environmental Pathway Analysis Scoping 5t uay pc r f ormet t for the Yucca Mountain Site (issued as SAIC-D7-8010, Mar:h. 1909).

[
( ,/
                                      )                    whether the current location of the ESF will be adequate to pr avide " representative data" for the site. The acquisition of too many samples could damage the integrity of t h c: cite;      the acqui sition of too f ew samples could 1.:.s d to improper c har ac t er i: at i on.        This, again, is cometh;ng that we plan to explore.
Ar iot he r question that has been raised by the ACNW cvouultents it whether DOE is using the most up-to-date methodu in acquiring information on the site. A factor in t hi c quect i or. Is t he requirement by the NRC Staff that only " proven" methods be used.                    This latter requirement may be hampering the range of technologies being applied by DOE.        We plan to explore it further.            One possible avenue, suggested by one of our consultants, would be to inquire about some of the techniques being used by commercial groupc, such as those i nvol ved in the exploration for oil.

Waste Confidence Decision. Prepared by We , t e Confidence C ec. i c w Group,-April 17, 1989.                                        I General Comment Thic document ic well and clearly n itten.        It review the findings of the 1984 Waste Confidence deliberations in a systematic rnanner and in the light of technical advances and legislative changes; particularly the offects of the 1987 Arnendment c to the Nuclear Waste Policy Act (NWPAA). I ri gen eral. the Review Group found no reason to abandon the con ~
clusions previously reached that successful disposal of spent nuclear fuel and high level wastes derived therefrom could be accomplished and that extended interim storage until the                <
avcilebility of the disposal repository poced no significant
                        ' additional rinhato public health and safety.
Perhaps the most significant changes in the rationale for the (relatively f ew) ' changes in wording of the findings          .
were (1) the recognition that the earlier congressionally                I established time table was no longer - if it ever was - at-              !
()              teinable and that it was prudent to project availability of the repository to some time in the first quarter of the 21st Century,_and (2) that the actual demonstrated accomplishment of dry storage of aged commercial reactor fuel at reactor sites gave'added confidence in the successful long-term cto-rage of spent fuel in the event of long delay in commission-ing-the disposal facility.        Such a delay could conceivably occur'if the congressional decree to qualify sites successively rather than in parallel turned out to have been
: a. bad-decision. .(Failure of the Yucca Mountain site to i
qualify could perhaps result in a 25 year delay in availabil-ity.)
The principal conclusion was t,ha t the various changes            ;
could have profound effect on the timing of beneficial use of the repository but no real effect on the confidence that the facility could and would ultimately be operative. The Review Group emphasized that it was far better to do the job right than strive to meet timing goals which were not of great                ;
significance.    .

                          -with possible exception of. DOE - which is subject to the regulatory pr oc ess . NRC is t he regulator. The State of Neveda, Nevada local govern'ments, and the national environ-mental groups are all apt to be interveners in the process and historically a n t i-n u c l e'a r .
Page 37.-para. 2.                  I wonder about DOE's capability for manag-ing a program as large and complex as the repository program.
What other programs of this magnitude has DOE managed and what was the result?
Page 39, para. 1.                  If there is a substantial delay in the availability of the repository will the additional cost to utilities arising from the need for additional storage at reactor sites be borne by the utility or funded by DOE 7 Page 47, bottom line.                  One of very few typos!

                        . General. The capacity of the repository is stated in terms of MTHM or MTIHM, specifically with a limit of 70,000 MTHM for the initial repository.                  This may make sense from a political perspective, but certainly doesn't from a technical point of view. The technical capacity will be dictated by the volume of the waste packages (which could be affected by rod conso-lidation), the thermal output of the waste, and the heat dis-sipation characteristics of the site. With a delay in avail-ability of the disposal facility, theoretically the heat out-put of the fuel will be reduced and a more dense storage                                l array could be accommodated. Also, the technology of rod con-solidation could improve. A corollary of this, is the undesi-

: t. he specific effect of higher fu l burnuo in the tenctor.
One'effect is tho reduction in the nunber of fuel anstwblies requiring dicrocition, however, each ascombly does contain a greater amount of radioactive material. This effect only appears after a number of yrvrc,-when the short-lived radionuclides have decayed away. The long term effect is a charge in the nature and quantity of actinide elements for the same amount of power generat ed by the extended-life fuel.
If it has not been done, it would sicem reasonable to evaluate the technical capacity as a function of fuel decay period, rod consolidation and other parameters that could affect the t<chnical cepacity of the repository.
Page 69. pare. 2                  DOE policy decision to dispose of the oldest spent f u'          i      will heve to be reviewed. The intent will undoubtedl                    keep reactors operating with minimum provicion for.o                  dry storage.          Since the fuel transfer rate to the repos            sry is hardly greater than the production rate, it is p r o ba bi r. that fuel ctored at shut down reactors will not be moved until all operating                    reactors with storage problems are taken care of                it is pocsible that a detailed logistics study at come time in the future would bet useful.
Appendix 2, page 2, item 1.                The average discharge of 30 Te
      ~~
MTIHM is probably realistic; however the refueling interval
          -i s not stated.        There is a trend for more extended operating intervals between refuelings.                  For example, Dresden 2 and 3 reactors are discharging on an annual basis about 22 Te of
          -fue.l. (These are 8004 MW units.)
Appendix 2,      page 2, item 2.          The_ curve of Figure 1 suggests a build up rate of1 from 20 to 24 Te per year assuming 110 reactors on line.            Is this consistent with the 30 Te per discharge cited above?
Appendix 2,      Figure 3.      The dry storpge requirements suggest that on the average each of the 110 assumed reactors will need about 500 Te of dry storage capacity at the end of year L          2047. This is not an insignificant cost.                    The total amount of fuel used in the same period assuming 110 reactors, and 25 Te j          per year discharge would be 40 yr x 25 Te/yr or 1000 Te.                      I think the consequences of extended delay in the availability of the repository could benefit f rom a reasonably detailed impact analysis.
