'3 CHAIRMAN SEALE:
The meeting will now come to i
4 order.
This is the second day of the 456th meeting of the 5
Advisory Committee on Reactor Safeguards.
6 During today's meeting the committee will consider j'
7 the following:
lessons learned from the independent safety 8
assessment of the Maine Yankee Atomic Power Station and L
9 associated generic safety implications; format and content 10 of ACRS reports to the Congress and the Commission; report l
11 of the Planning and Procedures Subcommittee, future ACRS 12 activities; and proposed ACRS reports.
13' A portion of today's meeting may be closed to 14 discuss organizational and personnel matters that relate
()
15 solely to the internal personnel rules and practices of this 16 Advisory Committee and matters the release of which would 17 constitute a clearly unwarranted invasion of personal 18 privacy.
19 This meeting is being conducted in accordance with 20 the provisions of the Federal Advisory Committee Act, and 21 Dr. John Larkins is the Designated Federal Official for the 22 initial part of the meeting.
23 We received no written statements or requests for 24 time to make oral statements from members of the public i
25' regarding today's sessions.

I 19 DR. KRESS:
Okay.
Well, first, just a little bit 20 of background for the members.
21 Maine Yankee problems started with an anonymous 22 allegation back in
'95.
This allegation was that there was 23 inadequate analyses of the emergency core cooling systems l
24 and containment in support of a power uprate, and I don't 25 know what exactly the inadequacies were -- maybe we will

and that they clearly had broader implications in areas like 4-what is the code validation and review process that NRC has 5'
and how do they go about reviewing amendments and tracking 1
6 of compliance commitments that are in SERs, maybe even'the 7'
review guidance for uprates and'in general the inspection-8 and audit program, so it has implications.and so this is a l
l 9
generic thing.
It's not just Maine Yankee.
It's what does 10 this mean with respect to the way we go about'doing 11 business.
12 NRC did put together a review team and came~out
-13 with a report that you'have in your package or had sent-to 14 you.
It has a number of what I thought were good

15; recommendations and the Staff put together an action plan.to 16-implement some of those, and I think today I gather we are 17.
having -- this is just a briefing and it's probably on the 18 status of this action.
19 So with that as a short introduction, I will turn 20 it over to John Zwolinski to introduce the Staff.

level of detail associated with some of the questions we 4
think are of interest to the committee.
5 Before I get started, I would like to thank you 6
all for the opportunity to afford us the opportunity to 7-bring you current on activities and efforts underway in 8
regards to Maine Yankee lessons learned.
9 You may have seen the materials provided the 10 actual lessons. learned numbered on the order of 33 items.
11 We-have completed on the order of about 20 of those.
We are 12-going to get.into some detail as to what is embodied-in 13 those.
14 To give you a little bit of perspective, when the
(
15 allegation was first received in December of 1995 both Dan 16 and myself were asked to get more deeply involved in this 17 particular project.
We were deeply involved in the order 18 that was issued over the -- on January 3rd of 1996 19 essentially derating the plant by about 10 percent power for 20 the next cycle of operation and through 1996 there are a 21 variety of activities that we will get into.
22 I think being dedicated to the facility, 23 representing NRR, and assisting Region I for the last couple 24 of yearc we have gotten into a lot of controversial issues.
25 The entire project is now at a point where we are L

5 With that as just an abbreviated overview, I'd ask 6
Dan Dorman-to start our presentation.
7 MR. DORMAN:
Thank you, John.
Good morning,

'Just briefly, the areas that we are going to 10 discuss I will fill in a little bit more as to how the 11 issues evolved during 1996.
I will give you a high level 12 overview of the 11 issues that were defined in a tasking L
13 memo to the Staff in November of '96 that grew into the 33 14 subissues that are in the report.that you have, (Jr')
15 I will briefly talk about what we are doing on the 16 power uprate issues and then I will turn it over to Ralph 17 Caruso, who has a brief presentation regarding some of the 18 analytical code issues.
19 As Dr. Kress mentioned, this activity was 20 essentially initiated by an allegation that the Staff 21 received in December of 1995.
The Staff did a preliminary 22.
investigation in early to mid-December of 1995 that L
23 identified some substantial concerns with the small break i
24~
LOCA analysis that had been done for the Maine Yankee Atomic 25 Power Station for Cycle 15 operations, which began in L (~

.In addition to the order that was issued by.the 3
Staff limiting power of'the facility in January'of 1996 the 4
Office of Nuclear Reactor Regulation initiated an internal j
-5 lessons learned review to look at analytical code issues, to R
'6
.look at' power uprate review process, and also, because the
.7 small break LOCA issues were directly associated with the
.8 resolution of small-break LOCA-related TMI action items for 9
Maine Yankee, this review also looked at how the Staff had 10 addressed the closure of small break LOCA issues for all of 11 the plants.
12 DR. UHRIG:
Was this peculiar to Cycle 15 or was L
l l
13 this a generic problem?
14 MR. DORMAN:
The issue for Maine Yankee was i
()
15' peculiar to Cycles 14 and'15 for Maine Yankee.
16 DR ~. KRESS:
What were the actual inadequacies?
17 MR. DORMAN:
The principal issue involved the 18 analysis across the full small break spectrum.
When the 19 licensee performed the small break LOCA analysis using the 20 RELAP 5 YA code, which had been developed by Yankee Atomic 21 for Maine Yankee and some other licensees that Yankee 22 provided services for, when they did the analysis for Maine 23 Yankee when they got up to a break size of.35 square feet 24 the output of the code was unstable following safety 25 injection actuation at that break size.

At that point the analysts at Yankee Atomic made a
/%
2 determination that they were already seeing the peak V
3 cladding temperatures coming down, therefore they concluded 4
that they had identified the limiting break and the peak 5
cladding temperature and did not continue to analyze higher 6
in the break spectrum.
7 The Staff's approval of the code had been for a 8
spectrum up to
.7 square feet.
The previous licensed 9
analysis for Maine Yankee had identified the limiting break 10 size of
.5 square feet, so they had not analyzed.or 11 demonstrated capable of analyzing for that portion of the 12 spectrum for this code.
13 DR. KRESS:
Was it just bad judgment on their part
.14 or --
(
15 MR. DORMAN:
I think that's -- that's I think 16 where the Staff has come down is that the people who were 17 doing this were somewhat isolated from industry and what the 18 practices of the industry were and what the expectations of 19 the agency were in this area.
They made a judgment and we 20 substantially disagreed with that judgment.
21 DR. WALLIS:
Maybe it was exasperation with the 22 code.
23-MR. DORMAN:
Exasperation on the part of the f
24 Yankee analysts?

Well, the code -- the code was

2 understand it was unstable, and it can be very exasperating _
%/
3 trying to figure out why that code is behaving that way.
4 MR. DORMAN:
In addition, this was a code that 5
they had spent I believe close to a decade developing and 6
had spent several years trying to get a good analysis for 7
the Maine Yankee plant with this code, so exasperation may 8
be a reasonable --

DR. WALLIS:
What kind of a plant is this?
10
.?Gl. DORMAN:
This is a Combustion Engineering 11-plant.
However, practically it looks much more like a 1
12 three-loop Westinghouse.
13 DR. UHRIG:
It's two-loop, isn't it?
14 MR. DORMAN:
No, sir, it's a three-loop.
[
15 MR. BOEHNERT:
It's an odd duck.
16 DR. UHRIG:
It's different than St. Lucie then.
17 MR. DORMAN:
Yes, sir.
18 DR. WALLIS:
Is part of the problem that it is an 19 odd duck?
.20 MR. DORMAN:
Not being a code expert, I can't 21 really answer how that affected the code, but I think the 22 problem was, as I understand it, was in the code, not the 23 plant.

Did they ever identify the 25 reasons -- it doesn't look like something that is easily i.

code and blessed it.
Normally one of the things you don't 3
. find unless_you just exercise the code is areas where it
-4 goes unstable.
5 MR. DORMAN:
One of the anomalies, really the 6
significant. anomaly with respect to how this Three Mile 7
-Island action plan item was closed for Maine Yankee, you 8
will recall that Item 2K330 required licensees to provide a 9'
new code for analyzing small break LOCAs; 2K331 then 10 required them to provide the Commission a plant-specific 11 analysis using the approved methodology.
12 For Maine Yankee the Staff approved the RELAP SYA 13 code in January'of 1989.
Over several years following that, 14
. Maine Yankee had difficulty applying that code for the i
15 plant.
16 In May of 1989 the Project Manager for Maine 17 Yankee at'the time sent a letter to Maine Yankee that 18 essentially said -- I can't quote it to you off the top of 19 my head -- but essentially it said, to the Licensing 20 Manager, we had a phone conversation the other day in which
- 21 you told me that the code was operable and therefore 2K331 22
-in closed.
Maine Yankee interpreted that to mean that they 23 did not have to submit a plant-specific analysis so the 24 Staff never reviewed a plant-specific analysis for this code H
25 for this plant until the allegation came in in 1995.

In 1997, they conducted the first steam generator 2
inspections, which were conducted after essentially h&lf a 3

They operated for'about-nine months 4
during 1996.
5' On this inspection they certainly would have been 6

11 The indications that they found in the 1996 inspection after 12 only a half a cycle of operation suggested that there was a 13 major uncertainty in the steam generators and there was 14 large costs associated with that.

That portion of the allegation that we 22

lessons learned review that was performed in NRR, and that
[
2L review concluded that there were substantial inconsistencies 3-in the scope and depth of reviews by NRR of power uprates 4
over the last 20 years.
5 The second issue came out of the ISA inspection,
~6 which concluded that Maine Yankee was unable to demonstrate 7l
' operability of two systems for. operation at the higher power 8
level of 2700 megawatts.
One of those was the containment l
9 spray system.
The other was the service water system as it i
related to heat removal from the component cooling water 10 11-systems.
12-DR. WALLIS:
What was the problem with that 13 service water system?
14 MR. DORMAN:
There was a question given with the
( f 15 licensing basis, ultimate heat sink temperature and the 16 configuration of feed exchangers that the licensee had 17 installed as to whether the service water system could 18 remove the full heat load of the component

17 MR. ZWOLINSKI:
To generalize a little bit and put 18 in context, it appeared that as the licensee went up in 19 these various power levels from 2440 to 2700, margins eroded 20 for a number of their key systems.
So some systems 21 essentially did not have as much margin as expected.

the containment spray' system,:the. central-issue on the -
7=
adequacy of the containment spray system was credit that the 8
~1icensee had taken for containment pressure post-LOCA in 9
assessing the adequacy of net positive suction head for, 10-those pumps.
As a result of that issue, another issue that 11 the.ISA raised was the clarity and intent of NRC Safety 12-Guide 1 and so that is also one of the ISA staff action 13 issues.
14 One of the areas that the ISA got into in some

Specifically, the 17 license -- or the staff, the ISA questioned the actuation 18 circuits for the containment spray system.
The licensee 19

were evaluating the quality assurance program at Maine 8
Yankee was they felt that i' was a toothless tiger, in other 9
words, it had little or no standing Uith the Maine Yankee 10 employees and several key departments.

concern to the staff, that there was a breakdown in that 12 area, and that was translated throughout the Yankee -- all 13 the different facilities Yankee serviced, as a generic --

Entergy came in to provide management 19 services for the company.
They entered into a contract in 20 February 1997 in which Entergy actually provided the 21 president of Maine Yankee, vice president of licensing and 22 regulatory compliance, and a number of managers at all 23 levels of management at Maine Yankee, but that was a 24 management services contract.

However, with.the decision to decommission, L 4 obviously, the ratepayers are going to foot that bill. I l L 5-know there are ratepayer groups that are contesting that -6 with FERC, but that is where it will likely end up. t L 7 DR..FONTANA:.Has decommissioning actively started l 8 or is there -- 9 MR. DORMAN: The last I heard, they were scheduled L 10 to actively start major decommissioning about now.
- Yes, 11
-sir. 12 DR. FONTANA: They are supposed to have a 13 set-aside of funds for that? 14 MR. 7,WO'LINSKI: Yes, sir. () 15 MR. DORMAN: Yes, sir. At the time of 16 decommissioning, as I recall, their decommissioning funds 17 were on the order.of $106 million. The estimate at the time 18 they entered decommissioning of the actual cost for 19 decommissioning was slightly over $500 million, with about -20 $125 million of that being associated with costs of 21 maintaining the spentifuel on-site. And I believe that 22 . Maine. Yankee is part of an action against DOE to try and 23' break that issue loose. 24 DR. WALLIS: Did anybody from the' media try to 25 . write stories about this?

~. 241 l' in Maine? 1 2 MR. DORMAN: All of these -- there were a number 1 3 of big media events in Maine. The allegation itself was big 4 media event. The IG report was a big media event. The ISA 5 report was a big media event. The shutdown of the facility [ 6 in Decenter of '96-and some of the issues that ensued were a 7 big media event, the decommissioning decision was a big 8 media. So, yes, there were a number of big media events 9 there. 10 DR. WALLIS: Yeah. 11 MR. DORMAN: The seventh item actually derives 12 from comments from the public regarding the conduct of the 13 ISAT. The ISAT used, in assessing Maine Yankee's safety 14 performance, they used the criteria that we have used in -() 15 SALP for superior, good or adequate. The public objected to 16 the use of those criteria and said, by definition, there is 17 no unacceptable performance if those are the criteria you 18 are using. 19 The action from the ISA was specifically focused 20 on the adequacy of those criteria in the SALP program. l 21 Since that time we have a much broader review of our 22 licensee performance assessment programs that is being 23 tracked on the Chairman's tracking list, and so this item, 24 this relatively limited item has been transferred to that 25 broader item.

DORMAN: There was not a measurable from Maine () 15 Yankee and that was why this came out of the Commission l 16 meeting and came in to this staff action. The ISA found a 17 substantial number of operator workarounds at Maine Yankee 18 and.the Commission then questioned, you know, for -- you may 19 have an individual workaround on system A and another one on 20 . system B, and you look at them individually, and neither of 21 them constitute a large impact. 22 DR.

And it is -- I think it is very i 6 'hard to assess in a quantitative way. I think it is more a 7 judgment of how do different operator workarounds in the 8 plant,.on different systems, have the potential to cause the 9 operators to be running off in different directions, trying 10 to be in two places at one time in responding to an 11-accident. And if that is the case, obviously, that would 12 not be acceptable and the licensee would need to fix those 13 issues. 14 MR. ZWOLINSKI: The temporary instruction-focuses () 15 very hard on the integration of operator activity, and, in f 16 so many words, being asked to do multiple tasks in a short 17 period of. time. 18 DR. WALLIS: So they didn't have events where this 19-showed up, where the operators were running around, as you 20 described them? 21' MR. ZWOLINSKI: No, sir.

I think ultimately the assessment of i ANN RILEY & ASSOCIATES, LTD. Court Reporters I 1025-Connecticut Avenue, NW, Suite 1014 Washington, D.C. 20036 (202) 842-0034
244 1 the ISAT was that there were quite a number of these things, () 2 .but that individually, they did not seem to be, any of them, 3 significant, and the Commission said, well, what about 4 cumulatively, and the staff did not have an answer for even 5 how to_ assess that, let alone what the answer would be. 6' CHAIRMAN SEALE: I think this is a very 7 interesting example that goes to Dr. Powers' case, or his 8 concerns for the status of a plant during non-routine l 9 configuration. We call it shutdown or low power events and 10 so forth. But, here again, you had a plant which was in H 11 this retubing exercise. I am not sure that there was a 12 great deal of, let's say, systematic assessment given to the 13 configuration they were in under those circumstances with 14 limited cooling capability, and I am not even sure what the () 15 status of the fuel pool was and so on. 16 But here you have a situation where.you are not in 17 the configuration that was the subject of your -- any kind 18 of IPE analysis, or PRA, or anything else. You are very. 19-much dependent on the judgment and the discretion, at least 20 .in that time frame, that was the configuration-of the plant, 21 and the' fact that there were a large number of workarounds 22 going on in the control room is not terribly surprising. I 23 You;know, I think that would -- you would almost be a little 24 bit unaware of reality if you thought there wouldn't be. I' .25 MR.

CHAIRMAN SEALE: So, essentially, it wasn't a 7 power. plant anymore, in that time period. 8 MR. DORMAN: Yes, sir. In that configuration, 9 yes, sir. 10-CHAIRMAN SEALE: So, you know -- 11 MR. DORMAN: But the workarounds that the ISA was 12 addressing were issues of how would the -- what burdens 13 -would be placed upon the operator in responding to an 14 accident when they are operating in a normal configuration t( ) 15-and something off-normal occurs. 16 CHAIRMAN SEALE: But I guess the problem I have is 17 'that it is difficult for me to figure out how you would put J 18 the control room into the workaround configuration if you 19 had fuel in the core. I mean there is no reason to believe 20. .that that set of circumstances would be tolerated once you 21 got the core configuration back in place and had a '22 legitimate requirement to have adequate cooling available, 23 I mean it is just a pile of instruments whenever you have 24 got the fuel out of the core. 25 DR. BARTON: I think what I understood the staff C,/ i ANN RILEY &. ASSOCIATES, LTD. Court Reporters i 1025 Connecticut Avenue, NW, Suite 1014 Washington, D C. 20036 (202) 842-0034

The type of 17-thing we are talking about is they know they have got 18 something slightly out of the' normal configuration, maybe a 19 valveLthat-is normally open-that is temporarily shut, but if 20 design. basis event A occurs, we need this operator to go 121-over and open that valve. Well, if we have a number of 22 these in a number of systems where, when event A occurs, and 23 we need the same operator to open this valve and go over to 24 this part of the plant and do this action, and go over to 25 this part-of the plant, then we are relying too much on the O .

One was from the NRR 24 lessons learned regarding the consistency -- or rather, -25 actually, the inconsistency over the past 20 years in the ANN RILEY & ASSOCIATES, LTD. l Court Reporters l 1025 Connecticut Avenue, NW, Suite 1014 l Washington, D.C. 20036 i (202) 842-0034 1

(J ) 2 Once we do have a standard guidance and have 1 3 determined what issues are appropriate for the staff's 4 review on power uprates, we intend to go back and look at 5 some of the past power uprates against that standardized 6 guidance, recognizing that at this point the staff has taken 7 a position on those uprates and any questions that we make, 8 or any improvements that we might require, would be backfits 9 and we would need. to justify it through appropriate 10 regulatory process. 11 If there's no further questions on the uprates, I 12 will turn it over to Ralph Caruso to address what we are 13 doing to address the analytic code issues. 14 MR.

I am going to discuss efforts that are ongoing right 18 now in NRR and RES concerning analytical code issues that 19 have surfaced as part of the Maine Yankee event. 20 The first slide here describes a number of issues 21 that were identified as a result of the Maine Yankee ISAT. 22 I would note that some of these issues have also become 23 evident through the advanced reactor reviews that have been 24 conducted over the past five to seven years. 25 The item at the top of the list, adequacy of code ()) ANN RILEY & ASSOCIATES, LTD.

Becauu: the 13 number of codes -- because the codes that are used by the - 14 industry-are large and diverse, the staff has adopted a () 15-rather ad hoc practice of reviewing them, and we have not 16 documented our review processes or our review standards.. 17 DR. WALLIS: Excuse me. This review invalves - 18 looking at the code, actual lines of code,.and trying to 19 figure out what is going-on there? Or does it involve using - 20 the code? 21 MR. CARUSO: In the past, the staff review process 22. has not generally involved looking at individual lines of 23 code or using the code itself, it has consisted of review of 24 the documentation, review of assessment reports, 25 occasionally looking at individual assessment runs and /) ANN RILEY & ASSOCIATES, LTD. -(_/. .1025 Connecticut Avenue, NW, Suite 1014 Court Reporters Washington, D.C. 20036 (202) 842-0034

CARUSO: Well, in the past that has been done t( ) 15. through review of-the documentation of, for example, 16 numerical methods, or the models, how the models are 17 implemerted. And, as I said, the code documentation 18 provided in the past has often not been as complete as we 19 would have wished, and this was identified as an area which 20 needs to be improved. 21' DR. WALLIS: .Isn't part of this because of the 22-long time.that somebody -- X -- works on the code in 1970, 23 writes something up, leaves the company, and the legacy is a 24' code this person wrote which no one else understands. 25 MR. CARUSO: I couldn't disagree with you at all Q ANN RILEY & ASSOCIATES, LTD. k_/ Court Reporters 1025 Connecticut Avenue, NW, Suite 1014 Washington, D.C. 20036 (202) 842-0034 i ,a, . - ~.
l 253 1-on that. t l (d \\ 2 The final item that's listed here as the code i l 3 catalogue refers to license conditions associated with the r .4 acceptance of a code. When the staff writes a safety 5 evaluation report, it usually includes limitations on the 6 use or-application of.the code in terms of the input or the 7 type of plant or limits of applicability of particular { l 8 models or components in the code. And one of the lessons 9 learned out of the Maine Yankee ISAT was that the staff did 10 not have a handle on what the conditions were for the use of 11 the various codes that it had approved. So one of the 12 recommendations was to develop a catalogue of those SERS and 13 the conditions. 14 To address these problems, the staff has.taken ( )' 15 several actions, and these actions are being performed by 16' NRR and RES together. We are developing a standard review 17 plan. NRR has the lead in this area, and we're developing a 18 standard format and content guide and a regulatory guide, -19 which is -- for which research has the cognizance under the 20 close -- in close cooperation with NRR. 21-DR. KRESS: Format and content for the 22 documentation of the code itself? .23. MR.

WALLIS: This is the source code that's 6 actually -- 7 MR. CARUSO: No. This is -- when we receive a 8 code for review, we receive a very large package of l 9 documentation, and the format and content guide says, when 10 you're going to provide us with this mountain of paper, what 11 should be there, what should it include, what kind of 12 documentation? l ~13 DR. FONTANA: How do you know the code matches the i 14 documentation? 15-MR.~CARUSO: Well, I don't have it here, but I'm 16 going to talk about some of the practices that we have 17 already started to implement for several code reviews that 18 are about to start, and one of the changes that we are 19-making in our practices is that we are requiring licensees 20 to provide us with the actual code. This is a change from 21 'past practice. 22 I think a large part of the reason why we have 23 never done this in the past is because the codes are so 24 _large that they have required large computers, and we just 25 don't -- we've never had the resources in the past to run , (^'j, ANN RILEY & ASSOCIATES, LTD.

But as I said, the-20 new practice as we're applying it to several codes that I'm 21 just about to get to in a few minutes will be changing, and 22 we will.be running the coder and we will be asking for the 23 . assessment of input data. 24 DR.

CARUSO: Well, that's finding errors in the 9 code itself. There's another aspect of independent checks 10 which involves the staff running our own codes to analyze 11 the plants, and that's really the independent check for an 12 individual plant application. So I'm hesitant to call it an 13 . independent check. I mean, we're the regulator, we are i 14 responsible to check the work of the licensee, and the staff s (v) 15 will do that. That's sort of inherent in the process. 16 DR. WALLIS: I think there's a difference in 17 philosophy, though. I think that the vendor is running the 18 code arm exercising it and e,weaking it in order to get the 19 results that he wishes to get. So it's always emphasizing 20 sort of a result-driven, trying to get a positive result, 21 and it would seem to me the staff would take the opposite 22 approach: take this code, check it for robustness, tweak 23 it, see if it gives you the opposite, the negative result. 24 An absolutely different approach, and it seems to be i 25 necessary that that be done.

This will allow us to-5 understand how the vendors or the code user is adjusting his 6 input to get the result he wants.

WALLIS: This sounds great to me, and I just 10 wonder why it has taken so long. 11 MR. CARUSO: Well, as I said before, one of the 12 reasons was computer time. It used to be that these codes 13 required very large computers, and the whole computer 14 environment has shifted, and the agency has made a concerted () 15 effort over the last couple of years to improve our 16 expertise and review in this sort of area. 17 DR.

Are the standards that you're about to impose 6 upon these codes of your invention or have they followed 7 from some consensus industry standard or some other 8 authoritative body that has given you the guide on how to 9 define all of these things? 10 MR. CARUSO: As I stated, the work that's being 11 done here is being done mostly by the Office of Research, 12 which has gone through a lot of this as part of the advanced 3 13 reactor reviews over the past eight years, and they have had 14 a lot of discussion with us, with you, with the vendors, GE, s(v i 15 Westinghouse, Combustion Engineering, about codes, because 16 that's what we needed to address as part of the review 17 process of the advanced reactors. 18 So we went to research because they had the 19 expertise in this area having gone through this for the 20 advanced reactors. 21 The schedule for development of the reg guide and 22 the SRP includes interactions with the ACRS and with the 23 industry to develop a set of standards that we can all live 24 with. 25 That's my next slide.

Let me give you some 20. more philosophy. 21 We understand that we don't want -- we don't want 22 to regulate to perfection. We can't do that. We understand 23 that. However, the applications of these tools are forcing 24 the developers to sharpen their pencils, to come up with 25 better tools because utilities are under competitive stress 7 ANN RILEY & ASSOCIATES, LTD.

1 264 1 to cut costs. So they're always pushing their developers to ( ')T 2 develop better tools. q 3 We have to, therefore, consider them more 4 carefully because they're cutting margins by doing this. So i 5 in the old days, we used to have 50.46, and we said, okay, 6 2200 degrees and 1.02 times ANS standard, this provides lots 7-of margin. Now we have best estimate codes that people want 8 to use because they want to reduce the margins. We have 9 risk-informed regulation where people want to use the codes 10 to support PRA arguments. 11 The uses of these tools are expanding, and 12 therefore, we have to -- we can't be complacent, we can't 13 just establish one set of criteria and say, okay, this is 14 it. The criteria are going to change over time, they're f% (%.-) 15. going to change depending upon the spplication. 16 I can't really say where the criteria are going to 17 go or what we're going to do in the way of criteria because 18 of the tension from the application. 19 DR. POWERS: I guess I'm not asking you for that. 20 I'm asking for a very simple thing, I think is that indeed, 21 there is some constraint on the depth and breadth of the 22 standards that you apply to code assessment, documentation 23 assessments and data, all the things that you're doing with 24 respect to these codes, that has a justification based on 25 what your needs are to carry out your mission. /) ANN RILEY & ASSOCIATES, LTD.

DR. WALLIS: Any code I write is 7 unintelligible to anybody else. ??ha 's my experience. I'm 8 a terrible codist. Don't hold me up.

POWERS: So there is some way to decide how 6' far to carry this -- how much detail there has to be here. 7 MR. CARUSO: That's what I was getting at in my 8 explanation that the level of detail is driven by the i 9 application. As you said, you're an engineer who worries 10 about.how well it works, okay. Hcw well it works depends on 11 the application. How close are you trying to shave the 12 margin. Are you trying to build the bridge that will hold i 13 one small car and you're going to build it just to that -- 14 to hold that' load, or do you want a bridge that will hold ()- 15' anything that can roll over it. 16 In the case of -- it depends on the application. 17 If the application demands a lot of precision, accuracy, a 18 lot of -- a very low level of uncertainty, then your 19 standards are going to be different than if the application 20 includes a lot of margin and doesn't require a lot of -- and 21 you can tolerate a lot of uncertainty.

I-think that is the problem with these old 5 thermal hydraulic codes is they have been put together on an l 6 ad hoc basis, and maybe that is why a lot of them should be. 1 7 redone completely from the beginning. 8 MR..CARUSO: Standards is going to be tricky. 9 CHAIRMAN SEALE: Well, that is why we are 10 concerned about it. 11 MR. ZWOLINSKI: Are you using the word " standards" 12 -in the context of acceptance criteria that the Staff will 13 use? 14 DR. POWERS: No, I think we are using it in terms r ( 15 of what is the quality and depth of the documentation and 16 assessment of the code that's required in a generic sense. 17 MR. ZWOLINSKI: The suggestion to possibly meet 18 specifically on that topic then seemingly makes a lot of 19 sense. 20 DR. WALLIS: I think it is like grammar and 21 equations in the normal mathematic paper which is 22 intelligible to somebody else, and very often the old codes 23 are not like that. They can't be read by somebody else with 24 understanding. 25 CHAIRMAN SEALE: We sparred with marshmallows in / ' ANN RILEY & ASSOCIATES, LTD.

278 1 the AP600 review. We kept worrying about the quality of (} 2 documentation, the robustness of the so-called descriptions 3 of how to run things and at what the results would tell you 4 and'so on for years and the cumulative effect of delaying 5 the resolution of those issues was to make that resolution 15 even more and more difficult as time went on. 1 7 We feel like you have to have those concerns, 8 those' requirements upfront,-clearly understood, so that you 9 will have a code that your people can put on the machine, 10 -use and have faith in the results when they emerge. 11 If you don't have that going in, you are not going 12 tx) be any better off with this approach than you have been 13 with the previous approach. You have got to have the 14 documentation so that you can honestly look at the code in a A() 15 critical way. That is what we are concerned about. 16 MR. CARUSO: Okay. We hear you. 17 DR. KRESS: I think, looking at your plans and 18 what you are doing, I think Novak Zuber would be pleased to 19 hear what you are talking about. 20 DR. WALLIS: I think this is wonderful.

J 9 (Recess.] l 10 CHAIRMAN SEALE: We are now back on the record. 11 We weren't up until now. The next topic has to do with the ) 12 report to Congress and the Commission and Bob Uhrig wants to 13 share his thoughts. He and Med have been beating on this ) 14 with a considerable amount of input from other members of () 15 .the committee, so Bob, would you share with us your 16 thoughts. 17 DR. UHRIG: This is our proposed agenda for today. 18 I thought I would start with a few remarks followed by a 19 couple of presentations, very informal -- one by Med 20 describing the meeting that he attended where the Staff l 21 briefed the Commission on the Research program and then some 22 lessons learned from the Herculean effort of Dr. Powers for 23 putting together last year's program, and then I did receive 24 some comments via E-mail, so I thought I would give each of 25 those individuals a chance to say what they wanted to say [T ANN RILEY & ASSOCIATES, LTD. \\m_) Court Reporters 1025 Connecticut Avenue, NW, Suite 1014 l Washington, D.C. 20036 (202) 842-0034 t-i
281 1 and then there would be general discussion and we'll talk (; 2 about an assignment followed by an early adjournment -- Q 3 maybe. 4 The schedule that we have, that we are facing 5 here, with respect to the Congressional report looks 6 something like this. You can see that by next meeting we 7 should have the issues identified. The following meeting, 8 the subcommittee meeting, somewhere along in November or 9 December timeframe. The initial draft should come out of 10 that subcommittee meeting, a revised draft in December, 11 feedback from the Commission in January, and the report to 12 Congress in February. 13 This I believe has come from the Planning and 14 Procedures Committee. I think -- am I correct on that? i 15 CHAIRMAN SEALE: Yes. Qf 16 DR. UHRIG: Okay. Now just for your information, 17 here are the conclusions that were stated at the beginning 18 of the report last year. They are the things that you would 19 expect -- the severe budget reductions causing substantial 20 deterioration in an internationally-respected program -- 21 CHAIRMAN SEALE: You have got to speak in the 22 mike, Bob. i 23 DR. UHRIG: Okay -- the deterioration occurring at 24 a time when the U.S. power industry is undergoing 25 substantial changes.

The Commission's 6 core: capability in the nuclear waste area has been .7 dramatically reduced and this could inhibit the Commission's 8 ' effectiveness and-timeliness in conducting the review of the 9 waste depository program. 10 'So that is basically what we told Congress last 11 year. The question is now what do we tell them this year? 12 Here are some thoughts on that, for what it's worth. 113. First of all, as we were talking a few minutes 14 ago,.this is the last report that we will send to Congress, () 15 and there are two views of that. One is sort of'a last j 16' chance to impress Congress with the importance of research 17 and the other'is why bother? 18 I'am not sure there is any need to repeat the 19 messages of the last year. I think they came through loud ~20 and clear, at least as clear as they are going to get to a i 21 busy Congressman, and the message, if anything, should be 22 positive about the benefits of nuclear safety recearch and 23 examples would be appropriate, and the one that I chose here 24 was the PRA research and some of the examples that were 25 cited in the letter that was put together with great .f ANN RILEY & ASSOCIATES, LTD. i \\ Court Reporters 1025 Connecticut Avenue, NW, Suite 1014 Washington, D.C. 20036 (202) 842-0034 h -mv-y t m tw,-
283 1 difficulty. yesterday would be appropriate for such a letter I'). 2 and the length of the report itself could be short, as short V '3 as three to five pages, or it could be something like last 4 year's, which I believe was 10 to 12, that order of 5 magnitude. 6 We probably could accelerate the schedule if we 7 needed to -- 8 DR. FONTANA: Seven. 9 DR. UHRIG: Seven? Seven last year? Okay. 10 The thought was that we might want to include the 11 1998 report to the Commission this year to Congress, and j 12 then maybe reference specific messages in the text of that 13 report. 14 CHAIRMAN SEALE: Excuse me, Bob. I had thought we /~' (N) 15 had already asked that that report be sent to Congress. 16 DR. UHRIG: Has it been done? 17 CHAIRMAN SEALE: That is what I am -- 18 MR. EL-ZEFTAWY: It has not been done, because we 19 still have to decide -- if you decide that that is what you 20 want to do -- but it hasn't been done. 21 CHAIRMAN SEALE: Well, since it has got a 1998 22 date on it and since we think it is important, it seems to 23 me that it would be -- 24 MR.

POWERS: Bob, one of the discussions I had 6 when we were peer-reviewing -- we solicited the Commission's 7 review of the report to Congress before we sent it out last 8 year, and we got together with Mr. McGaffigan, and I think 9-he telegraphed to us some pretty good advice. 10 He is a former staffer for the Congress and it is 11 the staffers who read these things first, and decide whether 12-they.go on to the Congressman or not, and what he-13 telegraphed to us is he-picked up the report and he said 14 .this is an advocacy report -- bingo. At least that message () 15' came across pretty clearly, and he says the trouble with 16 those is that advocacy reports get de-weighted almost i 17 immediately by the staff. 18 Then he thought we would be better served if we 19 had written a detached report, much more akin to what we g, 20 prepared for the Commission, but I think even a step more 21 detached than that. 22 I think that was pretty good advice he gave us 23 there, and it certainly weighed heavily in my thinking that 24 it is very itnportant that I not write this report because I 25 had written that one and I would keep trying to write that O ANN RILEY & ASSOCIATES, LTD.

285 1 same report again. /) 2 I think that if we opt for your last chance to %.J. 3 impress Congress mode of action up there we give real 4 serious consideration to taking McGaffigan's advice and 5 write a report that drips with detachment, just like this 6 last one dripped with advocacy. 7 I would hope that McGaffigan could pick this up 8 and say now thin is a detached report -- with the same 9 confidence that that is what it was that he could say that 10 the previous one was an advocacy report. 11 DR. KRESS: What characterizes a detached report 12 as opposed to an advocacy report -- a balance of negatives 13 and positives or -- 14 DR. FONTANA: The first thing to show is you are () 15 not -- you are in a balanced position to start with. 16 DR. POWERS: I think it is the cheerleading aspect 17 that Bill pointed out several times in preparing the letter 18 yesterday that has to be excised rapidly. 19 I think a preamble in the report that says that it 20 is a detached report telling them what the status of 21 research and research needs are, and avoiding using 22 essential, critical, necessary and replacing those things -- 23 it would be useful, there would be advantages gained by, and 24 things like that. 25 DR. KRESS: Okay. That helps me a little. Thank (O ANN RILEY & ASSOCIATES, LTD. (_,) Court Reporters 1025 Connecticut Avenue, NW, Suite 1014 Washington, D.C. 20036 (202) 842-0034
_.._..___m._ 1y 286 1 you. ~ L/) 2 When I get ready-to. write a letter or report or in l N.) 3 the past when I used to do things like that, one of the 4 things that I always started out with is right at the top i 5 before I started the thing was a question -- what do I want 6 this report to accomplish?. What do I want this thing to do? l L 7 What is.its real purpose? Not because I have to write a L 8 report to Congress but vrat do I really want this report to 9~ do. 10 If we could identify that_first, then I think the 11 report,_ nature of the report stems from that. I don't know 12 exactly what it is yet we want to accomplish by this 13' particular report. 14 DR. POWERS: Well, ycu will fin, as I found, for -( ) 15 both reports, the report to Congress and the report to the 16 Commission, that the central theme is by far and away the 17 hardest job that you have to do. 18 Once you decide on that, usually after a year of 19 sitting through committee meetings and subcommittee 20 meetings, the ammunition that you have is there in 21 abundance. 22 DR.-KRESS: Even before I end up with a simple 23 theme -- I mean the question I am asking is what go I as the 24 ACRS want this report to accomplish for ACRS? That is the 25 question -- and then.the central theme that you end up with l / ANN RILEY & ASSOCIATES, LTD. l Court Reporters j 1025 Connecticut Avenue, NW, Suite 1014 l Washington, D.C. 20036 (202) 842-0034 i
287 1 may stem from that or it may not. You could get that with a V(N 2 variety of themes, but I still don't know what it is we want 3 this report to do for us. 4 DR. UHRIG: I am in the same situation here is I 5 don't know how to write a report that isn't an advocacy 6 report of some sort unless you are in a judgmental situation 7 where you are reviewing something for somebody else. 8 Are we put in the position then of reviewing this 9 program for Congress and saying this is bad and this is 10 good? Is that the kind of thing you are talking about? 11 DR. POWERS: That would certainly be an approach 12 to things, to say this is bad, this is good, this is 13 omitted. 14 DR. UHRIG: And this is an open invitation to have O) 15 your budget cut by a third. x_/ 16 DR. POWERS: Yeah. Or increased by a third. 17 DR. FONTANA: Even though this is detached, we are 18 supposed to be detached, but isn't the message we are trying 19 to get across is that the starvation of the research budget, 20 internally by the NRC, to fund some other things, is not 21 something that should be done? 22 DR. UHRIG: Well, that is internal to the NRC, and 23 Congress does not control that. 24 DR. FONTANA: Well, we ought to say something 25 about it. .

It is like many things, you j 5 have got to get through the first hurdle or you aren't to 6 going to get into the rest of the race. And I think he was 7 telling us, and I believed every word he said. That when 8 these people receive advocacy positions from a variety of 9 different sources, then tend to down-weight that 10 automatically. Now, he did not say they discounted them. 11 He didn't say they threw it out. He simply said that you 12 come in with extra baggage when you are taking an obvious 13 advocacy position. 14 DR. WALLIS: I think you have to tell an l N) 15 interesting story, and you have to have a beginning which i 16 makes someone want-to read the rest of it. Just like when 17 you pick up a novel in the bookstore and look at the front 18 page, and you say, is this something I am really interested 19 enough to go further with? So you have got to have some 20 really good words at the beginning and make them say this is 21 a story I want to read some more about. 22 DR.

We don't need to spend a 7 lot of time on this because I am sure you have all read it. 8 But to remind you, from the executive summary, the ACRS 9 review of the nuclear safety research program was to examine 10 the need, scope and balance of the reactor research -- 11 safety research program, determine how the research office l 12 is positioned for the changing environment, how well the 13 office anticipates research needs, the active role dealing 14 with some of the initiatives of the Commission, namely, the p; y) 15 SECY-97-075 dealing with core competencies, and SECY-97-167 x. 16 dealing with -- I have forgotten what it is. 17 Recommend whether the Nuclear Safety Research 18 Review Committee function is needed. And, of course, that 19 is history at this point. So it is really the four tasks 20 there that I think we have a continuing responsibility to i 21 face up to. 22 I am going to skip one of the slides, go on to -- 23 here are some of the changing conditions that we are faced 24 with, and every one of these is going to have some impact on 25 the research program, or the research program should in some /G ANN RILEY & ASSOCIATES, LTD. \\s,) Court Reporters 1025 Connecticut Avenue, NW, Suite 1014 Washington, D.C. 20036 (202) 842-0034 l

Is there research l 5 being done in this area now? I mean we already have the 6 petitions. 7 DR. UHRIG: There is a lot of research being done 8 in conjunction with aging, which is a very important factor 9 in the license renewal. The issue of Congressional action i 10 to mandate performance-based regulation is an issue that 11 could and is, to a certain extent, being addressed by 12 research. There are continuing improvements in the average 13 performance of the licensees, but that asymtotically 14 approaches a limit because they are a very high online

There's continued efforts at V 16 consensus standards that are important to the industry. 17 Research does participate in that. Continuing efforts by 18 the nuclear industry, including the cost of regulation. I 19 am not -- 20 DR. SHACK: Continuing efforts to reduce costs. 21 DR. UHRIG: Reduce costs. Okay. That's what it 22 must have meant. The emergence of new technologies such as 23 digital electronics. This is another issue that is 24 important from a research standpoint.

LJ 3 And one identifiable top level requiremel:c for the 4 NRC research program is they should focus on the_ issues of 5 most risk and regulatory significance. So that is a 6 guideline for the issues that I think we probably need to 7 address in our report. 8-CHAIRMAN SEALE: Bob, there is one item in 9 function 1 there that you didn't underline or mention, but 10 it seems to me it is something that we ought to search our 11 data banks for, and that is the question of whether or not 12 the Commission has the technical basis for making some of 13 the policy statements, or initiating some of the initiatives 14 in policy that they have done in the last year. -s 7(,) 15 If they have had to go off half-cocked because 16-they didn't have the research space to make a better 17 decision, or let's say a more informed decision, I should 18 say, I think that is something that might be worthwhile to 19 have in the report. Point out to them that they were forced 20 to make a more conservative decision because they didn't 21 have the data they needed to make a best factual decision. 22 DR.

307 1 is a list, if you will, of the desired attributes of a good () 2 research program in a particular area. That is, it has a N_- 3 systematic tramework for defining its needs and assessing 4 the value of the results and so on. 5 It has a practice of scrutable comparison of 6 alternatives in addressing the issues that are involved, and 7 it has a process identifying and prioritizing research needs 8 in that area. 9 If there is such a program in the NRC right now, 10 it's the overall effort in PRA.

Basically that is a new position for 17 them except for Larry Shao, who was originally in there, so 18 I think the Commission acknowledged that the Inspector 19 General's report is being critical of the Office of 20 Research. 21 They acknowledged receipt of the ACRS letter and 22 said it's been perceived very, very helpful, probably in 23 this stage of -- they haven't really gone through it yet but l 24 just first look at it it's been very, very helpful. l 25 DR.

I think Commissioner Diaz raised the point that i V ) 3 there is a lack of criteria of proper balance between the 4 use of the outside contractor and the inhouse research so he L 5 basically was asking the Staff, specifically the Office of 6 Research, to either define the criteria to -- find the l .7 proper balance between the outside and inhouse work. 8 Commissioner McGaffigan also wanted to know how 9 you'-- at least amplify on how to -- the philosophy of 10 saving FTEs by doing research by an outside contractor. 11 The Chairman sort of like agreed with Commissioner 12 McGaffigan and Commissioner Diaz on those points. 13 Commissioner McGaffigan also acknowledged that the 14 report that we have, mentioning the generic safety issues. () 15 It's a very good point and I think the Office of Research 36 has to resolve the generic safety issue problems. 17 Ashok Thadani mentioned the fact -- I think what 18 we wrote in our letter that Research has been very helpful 19 in the AP600 letter, so that observation was very good on 20 Research and I think Dr. Wallis mentioned that too.

When the assumption that what you can do now is 18 good enough that pervaded Mr. Christie's talk yesterday I l 19 think is a very bad assumption to make. I think we have p 20 some pretty good examples of that that came out of the 21 'AP600. When the line organizations are confronted by new 22' technologies, their natural tendency is to say what can we .23 do now rather than saying what is it that we should be able 24 to do with this new technology. l l 25 The example I trot out is not a particularly good l L ANN RILEY & ASSOCIATES, LTD. l - Court Reporters 1025 Connecticut Avenue, NW, Suite 1014 l Washington, D.C. 20036 L (202) 842-0034 l 1, . ~. _

.from the management of the organization and seemingly from 16 the Commission that some of the strides that have been made 17 by giants in the past were good strides but we still need to 18 keep going. My best example of that is right in George's 19 bailiwick, that we have a tremendous understanding of PRA 20 during the operational events and no understanding at all 21 during shutdown events. I do not see how we can live with 22 that. 3 It's driven home to me when I see the results of 2 24 the fire assessment where I went in thinking, well, fire is 25. pretty well taken care of and we'll not see much core damage l' O ANN RILEY & ASSOCIATES, LTD.

I would be scared to 17 ' death that I would be coming in here and saying this 18 component has a low safety significance and it does for 19 operations and it's absolutely crucial during shutdown -- 20 but1I wouldn't know it. 21 One of the themes that we tried to carry out in 22 the previous report is that if NRC is really serious about 23 wanting to do things better, faster and cheaper, the 24 question is no longer how can Research help.

We have already talked 6 about the report card. I am glad Dana gave it a name. The 7 report card particular research activities. But there is 8 another question we might want to try to address here, and 9 that is how the NEI can benefit from NRC research. That is 10 what the Commission needs to know when they argue with NEI 11 about the fact that there is a requirement for a level of 12 research. 13 And we had a perfect example yesterday in Bob 14 Christie's discussion. He completely ignored the fact that n () 15 the capability that he planned to bring to his industry's 16 process of managing ourselves and leave us alone was very 17 heavily dependent on the results of methodologies, 18 capabilities and so on, that were developed as a part of the 19 PRA, IPE, and the pilot studies processes. Completely 20 ignored the fact that those methods were a part of his tool i 21 bag. And so now he is going to freeze everything in place. 22 What if he had frozen everything in place two years ago? Or 23 five years ago? He wouldn't have anything. 24 And so it strikes me we ought to ask ourselves, 25 where has the industry benefited from NRC research?

Maybe we want to say them slightly differently if we 4 need to. And then look at what has happened over the past 5: ' year and.say' how has this happened? 6 The thing I see the greatest need-for, I have said 7 it already today is proper appreciation, articulation of the 8 .need by the parts of the agency that have the need. And I L 9 think research'is quite able to respond. I think we can 10 probably pick out if we need-examples from the past, it i 11 would probably be best if wel picked out examples, maybe PRA 12 is one, maybe there are some other ones, of successes in the 13 past year, where this format of really specifying the need L 14 and really responding to it, and showing that the response () 15: satisfies the-need, actually worked. If we can show some 16 examples of that. i. 17 We may actually have to show some examples-where 18 it didn't work. And I think we may need some examples where L 19 research itself, through its creativity and awareness was -20 able to perceive a need which then later.on got recognized 21 by the users, because I think that also sometimes happens. 1. 22' But I do see that you have to tie in this need, because that 23 is --'that is needed.

Considerable gains in safety are 3 considered. 4 We need to identify future areas where the present 5 state of knowledge may be inadequate. Some of these are 6I outside the realm of hard science where we are all i 7 comfortable. So some of these thoughts are kind of random. 8 But I don't mean to denigrate -- there are hard science 9 areas where we all agree.that work is needed such as 10 improvement of thermal-hydraulics models, steam generator 11 inspections and two plug-in criteria, and aging of 12 equipment, et cetera, aging of analysis technology. 13 But I thought I would indicate some areas that are 14 kind of on the edge of hard science.

- 3-Are there measures by which you can indicate how these 4
activities really are affecting risk?~ Those measures may be 5 do-able.. Software testing. What I heard and this is not my 6 -area, but what I heard about software testing is that if you 7. use the right process, you will probably get a good product. 8 But I think what is'needed, and I understand it can't really ' be done now, is some kind of a test and acceptance criteria 10-that measures the performance'of that software rather than [ 11 only looking at if you follow the right processes for l l 12' ' developing the software, you will probably get a good !~ -13 product. 14 Licensing extension -- .

FONTANA: Licensing extension rests heavily on 19 aging and particularly areas of assuring that equipment will 20 last until the next time you look at it. And some of this
- 21 involves inspection and assessment of structures that are L
22 inaccessible. 23 We all know about the effect of deregulation and .24 competitive pressures. Are there techniques for predicting 25 the effects of under-funding on safety, for example?

And I think they are trying to do better, and I 6 think they probably will do better, so I won't get into 7 that. ~8 If we are going to review l-- if you are going to 9: review and do a report card on present programs, we probably 10 oughtlto have access to the 189s, and at least look at the 11 scope. I don't think we should determine the quality of the 12 work, this can be.done by peer review, but we need to 13 determine whether the scopes and promised deliverables are 14 consistent with future needs. I 15 With respect to making recommendations, I don't 16 think we should be constrained by budget considerations. -I 17 think we ought to. indicate what we think the recommendations 18' ought to be and then the prioritization within the 19-constraints of a budget really ought to be done -- well, 20' ought to be done by staff using criteria which we think are 21 good criteria. But I don't think we ought to not make 22; recommendations because we don't think the budget is there 12 3 ~ to support it. 24-With respect to the letter to Congress, I think we 25 need a balanced approach. We need to be kind of global in [ \\ ANN RILEY & ASSOCIATES, LTD. Court Reporters 1025 Connecticut Avenue, NW, Suite 1014 Washington, D.C. 20036 (202) 842-0034
334 1 our recommendations. Again, I don't think there is anything . y['N ' '2 wrong with repeating things that we have.said before. .You 3 know what the old preacher said about tell them what'you are 4 going to say, then tell them, then tell them what you said. 5 There is goodestuff in the old letter that I think we really u 6 ought to repeat. 7 Finally, I think that Congress -- I don't know how 8 ~ to say this, but the Congress should direct the NRC to 9: maintair.-a viable research program. They can't just give 10 them a pot'of money and say do whatever you want with it and 11 let them take it out of important areas to put in other 12 areas that they consider to be more near-term, providing i 13 near-term -- t 14 DR. UHRIG: But Congress can't manage the research 15 program. L16 DR. FONTANA: No. But can they tell NRC, say, you 17 know, we expect you to maintain a viable research program? 18 Can they do.that much? 19 DR. UHRIG: Well, they do that. They do that by 20 approving the funds. 21 DR. FONTANA: They give me a whole of funds. Can 22 they -- 23 DR. UHRIG: Oh, okay. You are saying that they 24 should specify the funds that go to research? 25 DR.

In fact, that is how they tried to e 4 eliminata the Southwest Research Institute, specifically 5 they targeted it. 6 DR. WALLIS: I think it is more than viable. I 7 tried to get at this in a few words I tried to write a few 8 months ago. It has got to be vigorous and intellectually 9 lively. And you mentioned Farmer curves. Some Farmer 10 curves have been around a long time. It is just, to me, the 11 first step in trying to explain things in a rational way. 12 And we get some curves from Belgium. 13 And so why don't we get at the next generation of intellectual level of understanding, where it is not just 14 ) 15 some kind of a curve sketched on one pi-ace cf paper, very e 16 one-dimensional, a childish sketch representing something. 17 Why isn't something coming out of NRC research saying this 18 is the next step to make it better? It is an NRC curve or 19 NRC three-dimensional thing or something that is an 20 intellectual level above just sketching a line on a piece of 21 paper. And responding to something which has been around a 22 long time. They ought to be generating ideas. 23 DR. POWERS: The temperance of your neighbor when 24 you call a Farmer curve childish is astounding. 25 DR. WALLIS: Much wisdom has come out of the O ANN RILEY & ASSOCIATES, LTD.

Dana, were'you ever J 5 successful in getting any of the user needs letters?. That 6 seems to me another piece of input in addition to the 189 7 that would be interesting to look at, sort of related to 8 Graham's question. 9 DR. POWERS:. Whenever I asked for a user.need 10 letter,-it was promptly delivered. 11 INE. SHACK: But.is there a catalog, the whole 12 collecti~on? Do we'know how many there are? 13-IN1'. POWERS: What we did not -- what I don't think 14 exists is a' catalog of the. user need letters that have been Lj ) 15 written, and should have been written. I think you can 16 probably find a catalog.of all of them. 17 What I found in the user need letters was what the 18 report says, is they are -- the ones I examined, and I have 19 to admit that it was -- it was piecemeal, it was whichever 20 ones I asked for, that you don't get a specificity of I need 21. this to do this job, this accurately, this well, and that 22 sort of thing. It is more of the nature of screw around 23 with this and tell me what you can find. 24 DR.

When we delineated for them an 4 approach toward planning, I think'we essentially said that. 5 That approach'to it.now, you may want to refine that, expand 6 upon that, and whatnot. But, again, I will caution you 7 against trying to carry-too many things. 8 DR. UHRIG: Here are the-areas that I took out of 9 the report last year. The itemization at the bottom I found 10-five additional issues that had not been included, although 11 some of them are more the ACNW categories, such as the 12 decommission and the environmental protection, but even if l 13 we just take those areas that are listed up there, and 14 assign two people to each one of them, it means that () 15-everybody is assigned to three topics, with two exceptions, 16 and I tried to do this and I can't make it come out l o 17 rationally without some arbitrary assignments, so I made 18 some-arbitrary assignments but it doesn't make sense to have j 19 somebody spending time reviewing an area that he has no l 20 interest in, so this is strictly a first approximation at l 21 it. 22 Let me pull the curtain. You can see the names 23 that have been put beside there and it's strictly -- there's l 24 usually one person who is an expert in that particular area L 25. and the other person hopefully has some expertise but there f ANN RILEY & ASSOCIATES, LTD. l ( Court Reporters i 1025 Connecticut Avenue, NW, Suite 1014 Washington, D.C. 20036 (202) 842-0034

UHRIG: Well, that is what I would like to '4 -have some discussion of now is how do we go about this, how 5 has it been done in the past. 6 Dana, can you elaborate on this? 7 DR. POWERS: Well, the way the previous report was 8 structured is that there was a chapter in which the 9 essential points that we wanted to make about the Research-10 program generically were made and then there is Chapter 4, 11 in which we delve into each one of these topics. 12 Basically what happened was that straw men were 13 constructed and then people realigned my wheels for me, 14 especially -- and bamboozled me. excessively on heavy section D) g 15 steel -- persuasively argued the need for heavy section 16 steel, but that was done as an interim measure. 17 The agreement that was struck with the committee 18 in the last, prior to the last report was that for this 19 report the responsible individuals would prepare what they 20 wanted to say on their various topics in a more determined 21 effort and rather than an abbreviated straw man that they r 22 subsequently revised and reconstructed. 23 In the end I thought the straw men worked out 24 pretty well.

CONCLUSIONS OF 1998 ACRS REPORT TO U.S. CONGRESS Severe budget reductions are causing substantial deterioration of the internationally respected capability of USNRC to conduct a forward-looking, effective safety research program. This deterioration is occurring at a time when the U.S. nuclear power industry is undergoing substantial changes in response to economic deregulation. These changes may have safety implications that must be addressed by the Commission. Research is needed to ensure that the agency effectively addresses these changes. The deterioration in research capabilities is also inhibiting the Q ability of the Commission to continue the evolution of nuclear reactor regulation to a risk-informed, performance-based structure. The Commission's core capability in nuclear waste research has been dramatically reduced. Further reductions could inhibit the Commission staff's effectiveness and timeliness in conducting reviews of the nuclear waste repository program and cause delays and additional expenditure or National resources. 1 i O I 4 y .r r

SUMMARY
i i The Advisory Committee on Reactor Safeguards (ACRS) review of the NRC Safety l Research Program is presented in this report. This review was undden at the reqd o l Commission. In the Staff Requim..s.ts Memorandum (SRM) dated September 9,1997, j Commission requested that the ACRS: l 1. Examine the need, scope, and balance of the Reactor Safety Research Program. j i 2. Examine how the Office of Research is positioned for the changing enviromnent. j i 3. Examine how well the Office of Research anticipates ind d-f i 4. Take on active role in reviewing ongoing Research Program initiatives, such as h j discussed in SECY-97-075 and in SECY-97-167. Recommend whether the Nuclear Safety Research Review CMm (NSRRC) function j 5. is still needed. i t
O o O A. The Charge to the ACRS i k Examine the need, scope, and balance of the Reactor Safety Research Program j 1. s The d-s to the ACRS to examine the Rwdi Program in terms ofneed, scope, and balance requires some interpretation. The ACRS has interpreted the term "need" to mean that the ~ e Pre i-ilshould: s i
- support current Commission initiatives, p
- provide the technical basis for future, anticipated regulatory actions, and l
- maintain essential technical capabilities that can reasonably be anticipated as being u for future regulatory activities.

7 .m. 2. Examine how the Offlee cf Research is positioned f r the ch=ging environment 'O To understand how the Office of Research is positioned for the +=neine environment, it was necessary for the ACRS io specify ror itseirthe changes in the environment that couid reasonasix be WM to affect the NRC in general and the Research Program in particular. The ACRS believes that the public expectation for ever greater psi-:-2 by its public institutions is an ongoing trend that has for several years had an effect on all regulatory agencies including the NRC. In addition, ACRS feels changes are occurring that are likely to affect the NRC and the regulation of nuclearpower. Among these changes are:
- economic deregulation of electrical energy production requiring higher productivity from existing nuclearpower plants, i
- aging of the existing fleet of nuclear power plants,
- premature retirement of nuclear facilities prior to expiration of their licenses,
- renewal of some nuclear power plant licenses,
- maturation of probabilistic risk assessment (PRA) technologies, 7

- Congressional actions to mandate performance-based regulation and more rational regulation

.j 3.O O O Lamiro how w;11 th2 Office cf Research anticipates research teeds The ACRS interpreted the charge to " examine how well the Office of Research anticipates research needs" to include anticipation of future needs and anticipation of current needs of the line l organizations for research support in the execution of ongoing agency initiatives and Staff Action l Plans. The Staff Action Plans currently being pursued by the NRC staff that might benefit from l research support are listed in Table I-1. Generic communications and compliance issues that are j being handled by the NRC staffand that might require research support are listed in Table I-2. I l 4. Take an active role in reviewing ongoing Research Program initiatives such as those j disenssed la SECY-97-075 and in SECY-97-167 i The initiatives ofthe Research Fivs-o discussed in SECY-97-075 [8] are to define areas of l core comi Lcy. The 39 candidate areas of core competency identified by the RES staff are listed l in Table I-3. The ACRS inw d this charge to participate in the definition ofcore swp ^-wes j r to be an ongoing task and chose to not explicitly address this charge in this report. Rather, the ACRS will report its activities and reviews ofis d program initiatives in later communications to the i Commission, once the RES staff has had.the opportunity to refine its ideas and appr-W The' initiatives in SECY-97-167 [9] deal with the movement of the responsibility for developing rules l and regulations from RES to the line orBanizations. The ACRS views this as an intemal management j issue and will adopt a performance-based strategy for reviewing these char a j i 5. Recomumend whether the NSRRC function is stiH meeded i The ACRS has interpreted the question conceming the need for the NSRRC function to { encompass the need for the function as it was performed in the past, the need for the function as [ conceived when the NSRRC was originally recommended to the NRC, and the ACRS view of the i need of an analogous function at the s..i time. f r l l I
O O AdditionalRegdressents Questions concerning the Research Program posed orally by the Commissioners have been interpreted as additional rys-.6 for the ACRS review of the Research Prospm. h Comminioners have asked the ACRS to address-
- the program.mic issues of research at the NRC, t
suitable criteria for terminating research programs, l t the rationale for the high priority for participating in international cooperative research

O O ~ O B . Directions to the NRC Research Pfogram Directions to the NRC Research Fivy i. have been provided by the Commission [10] and are - j i . listed in the documentation for Direction Setting Issue 22 (11]. These dirwim are listed also in the Strategic Plan for the NRC [12]. The ACRS has identified three top-level functions for the Research Prey-ii from these sources: l 1 Function 1: Provide the technical bases for regulatory activities of the NRC line organizations 'and for the - I policy initiatives of the Commission. l Function 2: l Conduct anticipatory research to enable tlie Commission and line ergeraions to address issues that are anticipated to arise. Fametion 3: t i s Maintain technical capabilities w.w.y for the Commission and line organizations to address issues that arise in the future. /~ i The ACRS has been able to identify one top-level, quantifiable requirement for the NRC l Research Pivy.co: T:p belReaguireasent: 'Ihe Research Fivy-u should focus on the issues ofmost risk and regulatory significance. D In addition to the obvious constraints of bu!qetary and manpower allocations,- the Rwa Pi6p-u is also subject to the unquantified constraint that it provide the m support to the line organizations. i
O O o-3 i _t C. ACRS Review ofResearch Activities k i i i To conduct its review of the NRC research activities, the ACRS Subconunittee on Safdy Research Fivap== met with representatives of RES, NRR, and AEOD on Novernber 4-5,1997 [14f '_ At this ms^ Jug, presentations were made by sepasives of the Electric Power RM Institute and the Nuclear Energy Institute on industry-sponsored and managed research pmgnuns. h objective of this Subconunittee ms^ ug was to collect data and develop draft positions for review i J { by the ACRS. At the time ofthe rsJ.g the NRC Research Program had.just W dtid budgetisJ./Jo s andwasexperiencingsomereorganization. Theiqs.u..aoftheGewin Perfonnance and Results Act had only recently been imposed on the Research Program. j !. Consequently, most of the plans for research were not firmly established. l, i ' The ACRS met with representatives of RES on March 5-7,1998 to discuss the Research j Program in detail [15].

O O O CONCLUSIONS FROM 1998 NUCLEAR SAFETY REPORT TO NRC Recommendation: t The NRC should adopt a systematic fi..cs.sik for the design and engineering ofits Research Prey r. that enforces a close tie between research activities and agency l needs,=== the value of the resuhs to be achieved by the sud, defines the requirements of the research, speciSes the functions of the is& activities, and j de6nes the urgency ofthe results. j Recommendation: TheNRC needs to adopt a r.ctice of scrutable :;omparison of alternatives in f addressing technical issues that require innovation in Selds that are not well established. Recommendation: i l The NRC should devise a process for id airyir.g and pfe:C g is& needs that l encompasses considerations oflong:. term benefits as weH as short-term user needs. The user-need process itselfshould be revised so that it better wr-~as the full range l ofresearch needed by line organizations. i l t Recommendation: l The NRC needs to develop its in-house risk assessment capability to the extent that it [ can be readily used throughout the agency. The in-house capability can be used to assess raates and to improve the planning ofresearch. [ [ t
O o O l CONCLUSIONS FROM 1998 NUCLEAR SAFETY REPORT TO NRC i i Recommendation: The development ofPRA methods should be better supported by the activities of AEOD with the aim ofvalidating and improving PRA.TJeds and results. Recommendation: NMSS should continue to use results from total systems performance assessment to guide the technical work contracted to the Center for Nuclear Waste Regulatory i )- Recommendation: 1 A formal organizational structure that identifies and prisih research needs and j subjects these needs to peer review should be put in place to ensure close coordii and coBaboration between the dc.@s ofim 4 results and the users of thosei results. t Recommendation: The NRC no longer needs most of the functions of the NSRRC. The Comrrussion j does need a Rsd Program and needs to ensure that this Pr%.ir, cm. fess to the l NRC philosophy of research and to directions given to the Program by the '3 Commission. l l l i
