3 i PROCEEDINGS 2 MR. NOONAN: We're here today to talk
.. 3 to talk about the allegations at Comanche Peak.
4 For the record my name is Vince Noonan, and I'm also the i 5 Project Director for Comanche Peak: What we'll do here ' (' 6 today is basically try to address as many concerns as we 1 7 can talk about, and those we can't talk about we'll take t 8 back and see if we can get the proper answers for you. : 9 i. What I'd basically like to do is' to get Larry Shao, who ' 10 is the Group Leader for the civil and mechanical areas, talk '
)
a 11 basically about the civil stuf f. With that, Larry, do you , l 12 want to start? j l . 13 MR. SHAO: My name is Larry Shao. I'm the Deputy l l 14 Director, Divisicn of Engineering Technology, NRC, assigned-s 15 to Comanche Peak as a Civil / Structural and Mechanical /Fiping , 16 Group Leader. ! i l l l 1; Altogether, in the civil area we have about 47 alle-i
.i* IS gations' and in the mechanical area we have 150 allegations, l ; l , 19 so altogether in the civil / mechanical area we have about 200 ' 't j 20 allegations we're working on. These allegations are related , l l ? ' 21 to design, construction, testing and inspection of civil 22 structures and mechanical components. '
l 23 When I was given the job, I tried to get experts on this , 24 team. The experts are in the piping area, component support ' 25 area, civil structure area, and the concrete area. One of i l
i I 4 1 ! my experts here is Bob Philleo.
~
Bob is going to just talk 2 about construction. By way of a little background on Dob 3 Philleo, Bob used to be the Chief of Structures in the U. S. ; 4 Corps of Engineers for about 40 years in charge of construc-( . 5 tion of mass structure in the United States. He was past
~~
6 president of the American Concrete Institute, and also past t 7 president of ASTM. J . S MR. PHILLEO: I was a director. 9 MR. SHAO: He was the director of ASTM, and he has 10 written many books related--as a matter of fact, one of the i-11 handbooks you cited is one he co-authored, so he can address 12 some of the concerns you have in the three areas you had. ,
, 13 One is on the concrete base mat cracking, one is on the con- i !
1 {' 14 crete cement tests and concrete strengths, and the other one 15 l also addresses the control of the designs. These three areas 16 we're going to address in more detail today. ' l l 17 Altogether, in my team we have about 17 people, six 1 l 18 working on the civil structure and 11 working on the mechani-19 cal piping, and they're all supposed to be experts in their ) 1 I { i 20 areas. ! 4 - l
? 21 There's a letter you wrote to Ippolito about a month , ' .-- {
22 ago relating to concrete strength. Bob, why'do'n't you address 23 that letter, what your findings were, and maybe try to ' \ {
! l 24 explain a little bit in general. Bob was involved in the i t
25 development of the concrete codes also, so he knows the l
s l E I background behind these codes. ) 2 MR. PHILLEO: The letter apparently was triggered by n
~ ?
I I 3 some concerns on the Richmond anchors, but it got into the ) i l, 4 general discussion of concrete strengths, per se, and winter l N 5 protection. It was pointed out--Attachment D to that letter ' l 6 has all the meat--that there were 18--or 36 cylinders, just l \ 7 the standard moist-cured cylinders that are used for accept-i 8 ance of the concrete which failed to make the strength of l 4000 pounds per square inch which, in g eneral, was the design' { 9 l l I 10 strength for the project. I ij We went through and checked all the mixed designs and l l l 12 found without exception all those cylinders that f ailed to l I
. 13 make 4000 were for a 2500 PSI mixed design. So we have found l 14 no place in our investigations where any of the standard t
15 cylinders on which acceptance of the concrete is based fell l 16 l below the design strength. There were, in fact, 36 of i I l these below 4000, but for those 2500 was the design strength. 37 t i 15 MR. SHAO: There are certain concrete differences;
; 19 for instance, only 2500 PSI. These are concrete mainly i ! 20 used for over-excavaticas where they've over-excavated the ,
i r ek and then tried to fill it up. These are not really l l' 21 k; . . . structure concrete. They are mainly filling concrete. 22 23 s was one of t.he % gs. We didn't know and couldn't tell-- 24 . i MR. SHAO: I
'S ' I think Bob did quite a deep investigation -
l
=
g ,,+68"'
l l 6 I and found out that most of the cylinders that were centioned l 2 ~ l' that failed-- l 3 MR. PHILLEO: I have a copy of Attachment D with all l 4 the. mixed designs indicated for every cylinder that was cited 5 there,9so if anybody wants to go into any degree of detail, -l l \ . 6 we can do that. As a broad-brush statement, none of the 7 cylinders cited in Attachment D and none in any of the work 8 that I have done failed to meet the design strengths. [ There 9 may be some because I did not look at all the cylinder i 10 strengths, but all those that were associated with allega- { i 11 tions plus a bunch that we picked at random where the alle- L 12 gations were not specific, we never found any where the . i
, 13 standard cured cylinders failed to meet the design strength,i l
14 MR. NOONAN: How many did you look at? i 15 MR. PHILLEO: We looked at three or four thousand, I , 2 16 guess. I'd have to go back and add them up. We looked at a ! i* j 1; bunch of them. - i j IS Now, the second half is how they deal with field-cured
; cylinders.
19 There, there were quite a few field-cured
- i
, j 20 cylinders that did not meet the requirements. It should i ..a ! f j 21 be noted, however, that there is not a rigid requirement for l l l ..
j ! 22 acceptance of concrete based on field-cured cylinders, but .
.I 23 the job specification says--and what the ACI, American ' ~l 24 Concrete Institute, code that it's based on says--that if the 25 field-cured cylinders f ail to meet 85 percent of the l .
l 1
. . ~ . . ~ . ..
7 I I laboratory-cured cylinders at 28 days, the contractor shall t 2 improve the protection. So it doesn't reject the concrete: 3 it merely rejects the centractor's protection devices and l 4 requires that he improve them. However, it might also be I 5 pointed out that the requirements for the field-cured i f I
+ 6 cylinders that were invoked on this job were those for 7 structural concrete out of the ACI building code, and there 8 is indeed some--a fair amount of concrete in the plant for .
1 9 which that is a legitimate requirement. Anyplace where you l l l 10 have suspended concrete slabs and beams, that is the correct l 11 requirement to use because you want the strength to be 12 attained fairly early, because when you strip, the thing has I
, 13 no support under it and you want to be sure you have the ;
14 s treng th. 15 Is that the 4000 PSI? 16 MR. PHILLEO: Well, it's the requirement--85 percent of l i t- , the standard cure. The standard cure usually ran over 5000; l I 15 however, if it fails to meet that, it should exceed th'e 4000
; ay 500 PSI.
19 I
! 20 Now, it's also true in the ACI standard for cold weather '-: . concreting that for concrete that doesn't have the support j
21 itself, like a slab and a beam, there are much more 'ienient 2, i 23 requirements which apply. And much of the concrete in the 24 plant would meet the categories that they define as the ,
~
t 25 concrete not having support itself. They did not choose to , I . _ _ _ _ _ _ _____. __ _ _ _ _ _ . . f
8 1 invoke those more lenient requirements on the jcb. I can't I l 2 really criticize the engineer for doing that because it makes 4 3 the job complicated if he got two sets of requirements to .
! 1 4 adhere to, and the inspectors always have a big row of which I \
5 one applies. So they wrote the more stringent requirements I 6 into the specification. -SuMdBYfGIIf04'Orsd3cy;l;indegs _ __ _: mew 7 das & y Q Q g , p g g y,e3 _ 8 vee 8fidWENstTfl"fsM6C IFUfestpb=17.icati6h7 That is , because 9 they were low, the contractor should have been required to 10 improve the protection. Whether he did or not, I don't know. i 11 That's largely a matter for the Quality Control-Quality , I 1 12 Assurance people to wrestle with. The thing I was concerned ; j 13 with from the standpoint of safety of the project is to see ! 14 whether those failures were in the suspended structural 15 concrete or in the more massive concrete for which the more 16 lenient requirements could have been applied. out of the 108 l l 17 there were only three that were in slabs or beams, and of i IS those three, two just barely failed to make the 4000; they 1 19 were right around 3900. One was down about 3500, so that i
$ 20 was one for which there was some legitimate concern. That } 21 was d'ealt with at some length on the job and was ultimately i -
22 disposed of by making Schmidt rebound bammar tests on the 23 questionable concrete and comparing it with sound concrete, I l l 24 and it was found to be satisfactory. ! t i 25 S the other 105 were in the more massive concrete that
* .- .. .- +
E-- - U l l 9 1 is not a suspended structure for which they could have, if I. 2 they had wanted to complicate the job, they could legitimately 3 have used more lenient requirements, in which case there ; I 4 would have been no concern for those. 8 hS ECY5Tcor3c3d,e g 5 3tetLO:'.R.7mrEWaT4@f a1-lWreltoLmeFetStheYfeWFdrishfEiii2.t!1e
\
6 g ut for a 105 out of 108 the specifications could have 7 been more lenient and there's no problem with safety. 8 But it was a procedural failure-- 9 MR. SHAO: It was a f1*S1Yt!T8MYrl. 10 MR. PHILLEO: It's 3t3QAg % t,tep p ot a safety. l g} MR. NOONAN: One thing that I'm tryinc to do in all of I f l 12 this is: We go through and we look at the technical reasons Now, we I 13 why it's either okay or not okay; we will do that. 14 might say that it's okay because we've done some tests or f l 15 l whatever, but we are going to try to identify--we'll call it 16 root causes--why it happened in the first place, and then i i i
;- we'll turn that over to the proper group of people te look i 15 at. ]
l
; 19 MR. SHAO: Also, we are looking at two things. We're j i l ! 20 looking at certain FSAR specifications and procedures. If 5 they violated this, we look at it further. So the violation,
, 21 1 i .- 22 we can cite them, but safety impact you really'have to fix 23 them. You have to maybe modify or do something, so when we can see a potential they are violating and they are safety g ] 25 impact, we can--
10 Il MR. NOONAN: You could also have a violation with no - i 1 i 2 safety impact. ! i 3 MR. SliAO : In that case we just cite them. l 4 MR. NOONAN: In your SER do you explain-- 5 MR. S*dAO : In SER we would differentiate them. There's i 6 a violation and a violation in safety impact. 7 MR. PHILLEO: Now, this letter thing leads naturally S into the third major point made in your letter, having to 9 do with the validity of the Schmidt rebound hammer for the !' 10 application in which it was used. One of the interesting f t gg things--we'll probably discuss this in more detail with Mr. - I 12 Walsh--in saying it was not valid, he used one of my bcoks , 13 as a reason for citing it. i j4 Let me make one comment there. On the p. 15 Richmond insert answer, we were under severe time restraints 16 l to get it in. In fact, we were doing so under heavy protests i I to get it in. I don't know if you noticed in the letters
.i ;-
i I' i i: 15 ' that were sent, it took four mailings to get all the ~ attach
; ments to the Board. But during that time, I think that 39 20 ried to make clear in there that he hadn't had much l ] time to really icok at this, and what he did look at bothered 21 {
g him. That was basically what he was trying to say.~~He did , n t have time to thoroughly research ANI or ANSI or anything 23 l , else that might app-7 to ASTM. He didn' t have tirce to really j t J l look at it thoroughly. l 2a. 1
\ \
l T
11 I
] MR. PHILLEO: He was correct in citing references that l
the Schmidt hammer should not be used as a substitute for
~
2 l 3 normal compression tests for accepting concrete. I am very
. _ . . . . . . . . _ l 4 adament about that point, that we not throw out the moist-5 cured cylinders in the. laboratory which are the basic accept :
( ' 6 ance medium for concrete and subbtitute the rebound hammer; 7 but it is a very handy device for comparing concrete. That's 8 about all you can do. The manufacturer puts a calibration ' 9 ; curve right on the side of the instrument, and I wish he 10 would take them off because it leads to more trouble than f' gi iti's worth to the people that get a rebound number and lock f 12 on the side of the instrument and convert .it to compressive t 13 strength. It takes a great deal of carefully controlled l 14 laboratory work to get a calibration curve for a given set c.f La ' 33 l materials, but it is a good device for comparing two con-16 l cretes; so if you have a concrete that you're completely ' i I t i g- satisfied with, that is not in question, then you make a l. ig family of tests on that concrete, and then you 're in a *
; position to take concrete that is in question and if it's of 19 i ! 20 approximately the same age and moisture condition, you can - g < i l ; g test that. If the questionable corcrete gives as high numbers '
i' .. 22 as the concrete you're confident in, then you have a reason-l 23 able basis for saying that the questionable concrete is no g longer in question. 25 MR. SHAO: I think is right when he says that l
12 i 1 if not used properly, the Schmidt harner test, that some of
. I 2 - the people just like Bob say just use a calibration curve and I
3 convert to the actual nurber. You can't do that. If you do I 4 it right, compare with same age and same roisture and then 5 compare with good concrete, something comparable you know the t 6 strength and you compare it, that could be very useful, too.
~
7 This is one of the things I think that has concerned us a lot is that on DimteningsthaMsom@Deflije S 9 you be there and see what-the-Sam-Hill they dobathersth3n /

11 MR. PHILLEO: There were some cases involving possible 12 freezing of concrete during cold weather where they used it 13 and only reported the nurbers, and that's fine; that's the way 14 it should be done. In some of the work cited in Attachment. t 15 D they were converting the compressive strength. I much 16 Prefer the first procedure, and all they report is the raw i I l i 17 data. Then you have a good basis for comparison without
)
i 15 worrying about calibration figures that are probably incorrect.
; I think that's all I need to say about the general 19 ,
i
. ! 20 strength issue that was raised in your letter with the . .- t f 21 attachment deal, although we're willing to pursue it to what-i '
22 ever length you wish to pursue it. i 23 No, I think we can go into more detail when gets here. 24 25 MR. SHAO: The second issue is the concrete base mat. l upm e e e
1 ! 13 1 MR. PHILLEO: Okay. This is the cracks down at the l I 2 ; bottom in Unit One. 'There was a great big massive donut-shape 3 pour, and there are, in fact, cracks across the narrow part j 4 .of the donut just as the alleger said, and one would expect 5 to get them. Concrete always reduces in volume as it dries ; a 6 out, and that's something you've always got to worry about. 7 That's why they put joints 'lilun that in concrete walls to get S the cracks in a groove where they can't be seen. That's 9 always a design problem to work around the fact that concrete 10 shrinks when it dries and massive placements also shrink l
)
I 11 because of thermal contraction. They heat up when the cement - l l 12 dehydrates. 13 This placement was designed to go in two pieces where , 34 the construction joined across the middle. I think that wculd i have been the proper way to do it. Somewhere along the line, 15 16 by the time they got into construction, the contractor was i j ;- given the option of doing it in two pieces or in one: and he I is chose the option to do it in one, which I guess nest con-g i
; tractors would do. It's a little cheaper to do it that way.
19 I So he did it in one. As I said, there was a rigid form on
- ! 20 4 . ; the inside of the donuts; so when the concrete shrank the ]
21 cra k's right where the construction joints would have been. 22 i Essentially there is the same condition there as if they'd ) 23 ' done it in two, except if they'd done it in two pieces , 24 there would be a ni.cc straight joint across there. Instead,I 25 l
14 1 I there 's a jagged crack along there. Structurally the thing
- l 2 behaves the same.
3 We can go into a lot of structural discussion to shew l 4 that it's not particularly significant. One of the cracks 5 comes across a very thick beam where all reinforced bears i 6 have to crack. The only way the steel can take up the 7 tension is for the. concrete to crack. They're designed that 8 way. Usually we distribute the steel so we get a lot of very 9 fine cracks, but the total length of cracks, the total width' 10 of cracks, is going to be the same whether there's a pre-11 existing crack or not. Drobably the mostrcompelling answer 12 to this is that the critical design condition in there is 13 for a postulated accident inside .the containment where the , i 14 whole thing is subjected to internal pressure. So the steel { 15 !i in there is designed to take that accident condition, and 16 l when that happens all the steel goes into tension and the
' l '., 17 concrete cracks in so many places, the concrete just doesn't gg figure at all in that most-severe condition; so the exfstence ! ; gg of a crack in that part of the containment is immaterial as i ! 20 far as the most severe leading condition in that containment ,
i k l 21 9 88* Essentially, the thing--just the way it's~ designed, only 22 instead of having a nice, neat joint across there, there's 23 a jagged joint which has been repaired so that there--on top,. 24
~ I 25 andthathasnostructuralsignificance;butit'sessentiallyl
15 1l in the design condition the way it sits there. ! l 2 MR. NOONAli: Let me ask a question. The contractor was 3 allowed to pour the concrete in one piece? 4 MR. PHILLEO: Yes. 5 . MR. NOONAN: Is that a violation of procedures to do 6 that? 7 MR. PHILLEO: I doubt if you can cite it. It's just 8 merely a change in the design concept. The designers had 9 considered that as being done in two pieces. For that very l 10 reason I doubt that there's a piece of paper anywhere that gy says it must be done in two pieces. That was just the design 12 concept. I can't say for sure; I haven't searched every
. 13 piece of paper that might be relevant. ,
j4 MR. SHAO: For this particular allegation we tried to close out the original alleger. That was last week, and he 15 l 16 l was happy with our findings. He had no problem with that i I findinc. I don't know whether you know the name of the i ;- i 16 alleger or not, but we did close out with him last week. 19 The original alleger: I'm not sure if I f 'O know who the original alleger was.
. .... l NR. SHAO: I have the name, but we can't say it. -
21
,'f1R. NOONAN: I would prefer not to say it, and ': hake sure we keep the confidentiality. We met with him last I 23 week and Dick Wessman from my staff was down here.
I MR. SHAO: On the phone. 2a. i
16 1 l 1 . MR. NOONAN: On the phone? Excuse me, this was one he l 2! did on the phone. If you need it, I'll ask Dick if that's 3 l 3 one of the CASE people. 4 Yes; all right. 5 MR. SHAO: The third issue is -the control room ceiling. ! 6 ; think the original alleger is I think hic 7 criginal allegation said that the fueling conduit, the dry-i S wall and the piping going in the area above the ceiling panel 9 in the control room are classified as n'on-cite and are ! 10 supported only by wires tnd that these are either made for 11 or are the result of seismic event. This allegation was l l g2 i criginally attacked by Mr. Jose. He looked into it. He also 1 13 found some allegations is valid. He then turned it to my l 14 group and also I found it as valid. We even expanded the 15 investigation a little bit and went beyond what he said. We looked at the whole control room ceiling. ! 16 i l i i g7 I don ' t know whether you're f amiliar with the regulation, I g 33 Regulation 129. There is Seismic Category One and non'-Scismic
; 19 Category One. gamic Category One is non-safety function. f ,. ! 20 You,have to design. The design should be in such a way it I' i
j cannot fail. l 21 The nc.1-Category One can't fail, but our 22 regulation say when it f ail that there must be "done in such 23 a way that failure would not adversely affect the safety , g function of the safety-related components. j J l l 25 So in Comanche Peak for non-Seismic Category One, they ) l
- j l
J
1 l_1_ l i . I - do a so-called Damage Interaction Study. When they do a
~ l l
h 2 Damage S.udy, they look at physical geometry, do some analyses. 3 Then they reclassify the non-Scismic Category into two, one 4 called Ca'tegory Two and one non-Scismic. Non-Seismic is when I 5 it -fails, supposedly the geometry of the layout in such a way I 6 it will not affect the safety of the component; but Category i 7 Two are close to safety-related components so they have to i S perform in such a measure that Category Two cannot f ail. 9 So in the Control Room ceiling there are heating,. 10 ventilating and air conditioning. They were classified as I 11 Seismic Category one. We have no problem with that. 12 The safety-related conduits that are classified as Seismic 13 Category One we have no problem with, but there are non- ! 14 safety conduits and lighting fixtures which they were . 15 classified as Seismic Category Two, and they're supposed to i 16 provide an analysis to show these seismic Category Two i l
^
l 17 components in such a way that failure would not affect the g g3 component; but they do not have very good analysis.- We'are
; not happy with the analysis.
19 Instead of doing a good dynamic I ; I 20 analysis, they do a lot of clone study analyses and then take
; y ~ ~.. .
l' j 21 interaction effect into account. So we point out to them l . l 22 and they agree with our finding. I y3
. Also, there are non-Seismic items such as sloping sus-l 24 pended drywall ceiling, acoustical ceiling and louvered !
25 ceiling. They should be designed in such a way that their

So we wanted them l 4 to provide either analysis or modify their ceiling in such a 5 way they meet Regulation 129, and they are committed to do . 6 that. But because of this problem, we are looking at s 7 area. I say that we see this problem with 'the Control Room; 1 8 what about the rest of the plant? Is it possible the same 9 kind of problem occurs somewhere else in the plant? They i 10 submit a program plan--that was October the 18th--I was not 11 happy with ?.he program plan. They addressed concurrency , i 12 quite well, but they did not address the generic issue I 13 was asking for so I'm still waiting for that. l 14 MR.

21 that? f 22 MR. SHAO: This whole thing is--as I said; the first l 1 23 part, I'm not happy with that plan in this area. I'm not g happy with that Category Two analysis and also the generic 4 25 attachment. J l
\
19 j Cne of the things that concerns us is that 2 whenever they have to redo something like this, it seems likel 3 they always have a tendency to go out and either contract to
,; have it done or start doing it themselves and just go ahead 5 and do it before the MRC even has a chance to look over what '
6 they're planning to do. 7 MR. SHAO: That would cost them money if they start to 8 do it and we tell them we don't agree. That's their probler. 9 If they're start enough, they talk to us first. 10 MR. NOONAN: 'They are in the process of redoing it. , i 3g When I was there, I was looking at it and I did talk tc them i n there. They've got the ceiling out. ; 13 MR. SHAO: Yeah. I told them don't use judgment so they! I 14 say this thing fall down it wcn't hurt the people. It , i 15 j doesn't tap,e a lot to hurt people's eyes or nose and people 16 can't function, so ycu better modify the structure, rather ! i l . g ;- than try to prove it. You see, their original judgcent is I ' i 15 I something very light can fall down, hit scccLedy en ti:e head 39 or eyes. I think-I said don' t do that to us because ncbody
! 20 can be sure about five rounds, ten pounds falling down; it I . " l 21 may hurt somebody. .

BANGART: The concern I was writing in regard to, 7 the HVAC-Supports was assigned to the Miscellaneous Team to 8 follow up on. There is a relatively extensive inspection 9 history related to the issue of the box and work done at the 10 cite and a lot of work that was done by the Utility themselves { I g3 in response to the concerns that were raised. We had two 12 people involved in the detail look at that issue. Mr. 13 Hunnicutt was one. Mr. Lee Ellershaw is a Reactor Inspector i 34 in our Region, but he was also previously an inspectcr in the la.
, Vendor Program Eranch, so he has been involved in inspecting 1
16 IIVAC vendors for whoever is supplying the components. Mr. g ,_ Ellershaw is not available today so Mr. Hunnicutt is going to g summarize the details cf the investigation that we underteck.
; 39 MR. HUNNICUTT: This allegation was where they had been s ! 20 alleging that the HVAC had not been analyzed for seismic '
s . : loads and stated that all HVAC components and supports l
} )
s inside the containment were not properly considered in regard i to the treatment of missiles. In other words, some other 23 j movable object could penetrate through the HVAC. And that the 24 HVAC failure during the postulated accident would allow the 25 l. 9
)
22 1 temperatures to rise to an unacceptable level inside the , 2 containment. We had previously inspected this on Report No, 3 445/831S and again on 6324 where we identified the violation 4 pertaining to the fabrication, installation and inspection 5 of the }NAC system components, i 6 i The licensee responded with corrective action and ' to other identified violations on June 28th of '83. This i 8 response also addressed analysis of the identified worst-9 l care conditicns being performed b Corporate Consulting and 10 Development Company, which had been the HVAC suppcrt design 3g enginecr. I g; During our other inspections we sampled the EVAC ducts 13 end supports in the Unit Cne cable shredding room and the ; y Unit one containment air circulction and cooling system. The g NRC craff ebserved certain dimensional and welding discrepan.cies g l simi'.ar to those that we had previously identified in the two i j g- reports because nearly all the fabrication and installatien i 15 had been perferreed by bondsc.en p for to the identification
; 39 of the first vi.olation. It appeared that the discrepancies 20 cWened by the NRC staff were very similar*-no worse, in ft g cther wcrds--to those that hhd origf.nally been identified. ~
We requested that TUC submit a discrapancy evaluation by 2 g their centractor, which was again related to Corporate Censulting and Develcpt.ent Company. We will es11 that CCL g in the future. e
} l 23 I I So our staff again made an inspection that included the j
~ ! (
2 CCL report and according to the CCL, we found that all the . 3 pertinent HVAC supports were analyzed for seismic icading. . 4 The' NRC staf f also reviewed the CCL report entitled " Seismic i l 5 Qualification Report of Seismic Category one Duct Work and l 1
- 6 Hangers for Comanche Peak Steam Electric Station." This s ;
7 report is identified by CCL as llo. A-424-81-06. The latest 8 revision listed here is June 1, 1983. That's Revision Nc. 9 6. This CCL rcport included the engineering work sheets, 10 hanger data sheets and computer printcuts that referenced 1 11 and indicated the inputs and the analyses used to maie their l l 12 calculations. The NRC staf f also determined that the CCL-engineered j 13 i ja hangers were analyzed using two different methods. One is 15 the well-known hanger-based cede called Stardyne, S-t-a-r-d-16 y-n-e; and the hanger-based analysis censisted of two codes- ! I i l i g- . hanger which is used to qualify your single duct transfers y n hangers using your finite element models and the FIASA, a
; 39 much mere complicated analysis technique, which can accom .odate multi-duct transfers and axial hangers.
( 20 ,
. .. l j I 11 be happy to go into the Stardyne if anyone is 21 i
interested; otherwise, I'll just quickly say that it is 22 , 23 a program that can be used for complex arrays of multi-duct 24 hangers and for thermal expansion analyscs of duct systems l 25 simulating a load. . l
* *~+ .. ~ . . .
24 1 The CCL report--paper is not important, but there are 2 48 volumes of it; in other words, you have to do quite a bit , 3 of work to get through it--presents a seismic qualification l 4 documentation for all the Bahnson Company Seismic category 5 One +:VAC ducts and hange'rs installed at Comanche Peak. The 6 NRC staff determined from the CCL data that the EVAC ducts 7 and' hangers are structurally accurate to withstand the post-8 ulated seismic loadings hs CPSES. . 9 Further, on CCL's seismic qualification report it shcws 10 that the seismic-qualified HVAC duct work is classified as i 11 Seismic Category One. Also, safety-related equipment Londed i
'12 in the duct work is seismic-qualified either by dynamic i
13 analysis or by shaker table testing using a full responsive l 34 spectra or by static analysis using one-and-a-half times the 15 peak of the floor response spectrum. , 16
! Due to the fact that all the corponents are analyzed l
[ to assure that they are structurally adequate to withstand f i g gg the postulated seismic loadings, there appears to Le no'need 19 for missile consideration with respect to the HVAC systems. 20 In pur report 8324 we indicated that the reactor containment ;
's ~ . 2 i l j 21 heat removal system did not rely on the HVAC system, but is 1
22 really c mposed of two separate containment spray'rAc'ircula , 23 tion trays, each of which has 100 percent capacity and, of 24 e urse, the containment spray has two functions. One is to 1 \ 25 rem ve the heat from the containment after postulated load, ( __ l
25 Il and the second, of course, is to wash entrained and suspended 2 material out of the atmosphere af ter postulated load. , i 3 The NRC staf f reviewed the FS AR and found that the 4 containment heat removal system was designed to assure that 5 the failure of any single active component, assuming the i 6 availability of either on-site or off-site pcwer exclusively, 7 did not prevent the system from accomplishing its design 8 safety function. 9 I'll be happy to answer any questions related to it. I 10 I have one question. I'm assuming from 11 what you said that the answer to this is yes, but just to bc l 12 sure and also I'm a little out of my element: In the con-l
, 13 tainment, the sides of the containment, where you have the' 14 HVAC system ducts going up the sides of the containment, p .
I 15 l are those seismically--not seismically--laterally supported? l l 1 16 l MR. HUNNICUTT: Yes, ma'am. They are laterally supported l l j i 17 to where they can only move within the seismic requirerents.
. I i
is These are large ducts. They transfer very large arounts of ( l 19 air. Roughly--let's see, the height of the containment is { , i i 20 252 feet, and I've forgotten the circulation capacity; but a e - j 21 the fans do continually circulate the air to keep from 22 stratifying. In other words, the bottom would'be at 80 23 degrees and the top at 190 or some other numbers, but they , l 24 _are seismically restrained to assure that under the postu-l 25 lated seismic conditions for the arca--I have forgotten the l D e4- ,%. e. ,m _ _ _ _ -_-___-e.

2 One of our concerns there--I'd have to check 1 3 the transcripts to be absolutely certain a.cout this, but it l
. is my recollection in June of PBS hearings testimony was that 5 they were not laterally nupported, and that was one of the l 6 things that was brought . up. This was during the hearings . . . . - - ~ . .-
7 on CAT Team fi _ndines.. - : 8 MR. HUNNICUTT: As I understand it--I hope my information 9 is correct--they were laterally supported to withstand any I' 10 postulated seismic event for the maximum allowed or permitted g3 , by the FSAR as Mr. Shao pointed out, .12. 12 That's one thing--I'd have to check on that
)
13 to be certain. }
} .1 MR. NOONAN: That was a June 30th-- , I There was a June 1983 hearlng. I'm not 15 16 sure what the date was. I'd have to check. {
i I MR. NCONAN: You say the NRC did a review? Whc was that? j - I was one; Mr. Ellershaw was the$ther: l 15 Ma. HUNNICUTT: )

20 who p e other people were. .' ~ c . 21 my mem ry doesn't fail me, those are the three principals. f l Now, we have had some input from a Mr. Cumings who"is the 2'2 current resident, and due to the fact there's a draft report q 23 ) l g under consideration right now. I don't recall but I know he j ! and I had authorship on portions. I can' t remetr'oer the numbelr. l 25 l I
l 27 1 Now, on 8416, in my infinite wisdom and hurry, I just copied' 2 the three pages that related to it; and I do not know who the 3 author was on the 8416. It was issued on October the 4th-- l 4 of this year, of course--and I only have pages 12, 13 and 14. 5 I apologize for not having this entire package, but when you 6 are in a hurry--of course, I didn't take it out of the site. 7 I think that's ene we just got recently. 8 MR. HUNNICUTT: You would have just gotten it because 9 it was mailed--it left our office on October the 4th, and ! l pages 12, 13 and 14--in fact, it would be paragraph 6--cover 10 33 a minor amount of your HVAC; and there's another ene coring 12 that really went through the CCL Phase 1, 2, 3 and 4 docu- , 13 ments that compared it to a licensee's evaluation. i y Specifically they had made a probability analysis that--I 15 l think it was 280 elements needed to be checked and CCL had 16 l done 285 so, in other words, they probably listed calculation's i l 6 g
- g. between the licensee and CCL were certainly within the basic l
15 mathenatical realm. We hope to get that report issued short-
; g9 ly. I won't make a stab at the number because I may be wrong. ! 20 MR. NOONAN: What concern was there? '
l l j MR. HUNNICUTT: Again, they neglected the use of the core spray system and containment spray, which each of the i 93 two systems is 100 percent available, and that is supposed I to reduce the temperature within a reasonable amount of time , 2a, f rom the highest postulated value to a reasonable value.
28 1 MR. NOONAN: But the concern would be that the tempera-2 ture gets too high and the equipment won't work? 3 MR. HUNNICUTT: That was our understanding of the l 4 allegation, yes. _ And.nrtym r;wasNauppofte spropH1y.

. s : .. ~ .. .. ,- _ m a m m, fg _ T= % 4: h= r-7 8 MR. NOONAN: I'd like to do one other thing, too. As !
9 far as the equipment inside,'do we qualify the equipment for! 10 what we call the high energy line, which is the main steam i
~
11 line, or ALOCA people. I don't remember the exact tempera-12 tures, but I'll get them for you. Equipment is usually 13 qualifiedtowithinarangeofsomewherearound300 degrees.l 14 MR. HUNNICUTT: Let me correct that; it's 275. j l 15 I was kind of thinking 280. 16 MR. NOONAN: We don't tell you what the equipment is i I l 1 i 5 1; actually qualified for. We'll give you the upper value. ' l ls MR. HUNNICUTT: If I remember correctly, it was 50' PSI l - - ; as designed and 40-something as the maximum calculated and 19 i
! 20 275 Fahrenheit would be the~ maximum temperature.

7 Before, I think you had one allegation that I'm con-S cerned with. Before we get back to the allegations, I think 9 it's appropriate to tell you how we handled the allegations.. 10 As you know, the quality control inspectors were interviewed i 11 and a number of allegations came up as a result. Most of i 12 them were general in nature; some of them were specific. 13 What we did is some kind of way we correlated all these j 14 allegations. One allegatien was talking about terminal , 15 locks. We're talking about bat splices; we're talking about 16 cable installation. We put them into about nine categories. l 17 l And regardless of the allegation which has safety significance j lb , or no safety significance, we went beyond that point. We 7,
, 19 kind of bound the subject categories with our own sampling, l )
i 20 looking in areas where we felt there was a real concentration ~
,.4 j 21 of . cables and problems of terminal locks or bat splices so l a * ~
22 we can identify whether there was some kind of~ generic 23 implications as a result of this. 24 The allegation you brought up, I think, touches termin' al 25 locks, touches cable splicing, touches cable installation,
. l S
4 . .. f.-..-.-. ~ ~ = = . .
30 I and I think also it touches nonconformance reports with
~
2 regard to cable operation where the cable was installed. We l l 3 acknowledged the fact that this particular allegation, the 4 formation brought up by the alleger was--the concerns brought 5 .up by him, there was no safety-related matter but we say let's
.. 6 see if the same problems are in the safety-related matters.
7 So maybe we can give him credit for th'ese things. I guess 8 what we did, we focused in that kind of direction. We did ; 9 find some problems with bad boxes. I want to give credit i 10 to s I do to all the allegers who contributed to 11 force us to look into that area so we did find problems there~.i l 12 We also have problems with terminal locks. = We have l 13 problems with terminations as we indicated in previous ; g4 meetings with the tJtility and in our letters summarizing i 15 ur conclusions.

31 I ts. VIETTI: cesn't know what 813..is. That'.s our - 2 NRC number- , ' 3 MR. CALvo: ows Oklahoma. One of the allegations l 4 brought up has to do with the use of locks for some dif ferent i 5 size cables', 750,000 circular mill versus the 1,000 circular 6 , mill, but that one located in the circulating water syste'.t. . 7 That system normally is not safety--I mean, it is non-safety , 8 I related, so we did not concentrate on that because why waste i 9 our time about the non-safety related. Let's concen.trate on ' 10 similar problems with the safety-related, 11 Also, the other allegation he had was building locks-- i 12 I go back to Switch Gear Room Reactor One. I guess this I 13 allegation came on 1981, 1982. We went and checked this oct 14 ourselves and found out that that thing was involved with i 15 some black cable, but definition of black cable is non-safety 16 related so we don't bether with that one either. I 17 We did look into also unmachined panels, :
.ike panels-- ;
j 16 Centrol Roor panels. Those also were associated with'b' lack .- 19 cables, also non-safety related, so we don't bother pursuing { l s-20 tha't one. No reason to spend our time. c { 2 1 21 There was another one that had to do with patching of 22 cables and with operation.; There was some nonconformance i 23 report. I think the nonconformance report was indicated as 24 in 1981. Thosc had been handl'ed in a manneri that was satis- ' 25 factory. Whether they 'were safety-related--they could or . t 9

32 1 they couldn't be construed as .non-safety related. We did i also look at nonconformance reports -in several areas to bound.k 2 3 all these allegations, so this contributed an input to the 4 other category for nonconformance reports. j 5 The only one that had some safety-related flavor was thei
- l. 6 Switch Gear Room in Reactor Number One. There was some prob-7 l lem there in No. 10 terminal locks. So what we did, par- '
8 i tiicularly for the terminal locks, we went and we reviewed

'l j 4 We had also the OA-0C allegation and we look into the elec-5 trical NCR activities. We found no problems insofar as our 6 small input from the electrical standpoint. We are waiting 7 for the big cverall input that QA-QC must link--couple with I
l 8 ours. We also looked into procedures, and we identified ' 9 ' problems'and we identified corrections to those problems. 10 Again, also, that one is not complete because the overall 11 OA-QC programatic review got to couple with that one.

36 I and look and see if we have a'ddressed the evaluation properly, 2 if there's something that we've missed. It's sor.ething like 3 a coordinator to look over the picture. We have three out-
.l 4 side consultants to do this, sort of, for us, to give you an I
5 independent viewpoint before we finally put it out to the 6 public. t 7 MR. CALVO: Our effort was not encompassing to pinpoint ' i 8 what the root cause, but it was focusing at the problems; and 9 now when we established the actions that needed to be taken 10 by Comanche Peak Utility, then after they do that work, then l-11 the root cause is estab,lished. It doesn't make any differency 1 12 whether they reinspect the whole plant or take a sample, - 13 a representative, regardless of what the confidence level, l 14 what the acceptance or rejection. The only problem we nave 15 with the rejection is simple: whether that one is reflective 16 of thn_fg!_qTreyg-It r could very well be that you will say, a j 3- 'I have met the acceptance criteria and that n.eans that I have i gg a root cause probler. and I have to go further regardless of
- ; 39 whether you meet the criteria or not." They've got to under-i 20 stand,that. It's not a part of whether you passed the test. , ; ;; . 9 1 l } 21 It's because you found when you passed the test that you had ' ~

problem. How big that problem is we'll know after we do 3 further samplings. That's all I have to say. l 4 MR. NOONAN: These three coordinators, their job is also 5 to look for what they can tell--as best they can, look at 6 the root causes. Make sure you address these areas that l * % h 7 we're worried about; why did they happen in the first place? 8 MR.

She's much more knowledgable about that .. 12 and what they have to say.
. 13 MR. KEIMIG: My name is Rick Keimig. I was the leader ;
14 of the group that was looking into the concerns in the test i 15 program area. By way of background, I have had in excess of 16 12 1/2 years with the NCR Region One Office in various

38 1 because of their similarity. The concerns expressed in ! l 2 CASE-Proposed Contention.26 were included in topic area 1, 3 3 and 4. I'll start off,with topic area 1 which is the 4 largest area and concerns eight of the items in Proposed , 5 Contention 26. - - ! 6 - The first concern that was expressed in CASE-Proposed , 3 7 Contention 26 was that the applicant failed to conduct an e 8 adequate prefueling hot functional test program in that not l i 9 all components or modifications were installed with required i i 10 functional testing. TRT reviewed this particular concern l l 11 and found that the hot functional test was conducted with l 12 several minor components and equipment not having been g 13 installed at the time of the test, and also found that 14 rodifications remained to be completed after the test was l 15 completed. , 16 In addition, we also reviewed some of the inspection I 17 reports of inspections conducted at Ccmanche Peak' including i i 16 the construction Appraisal Team inspection and several others, 19 as I mentioned. The ones that we reviewed we looked spe-i
! 20 cif'ically for any evidence in those inspection reports that i ! 21 would give indication of any undocumented--I emphasize i u . . . . .
l 22 undocumented--components and equipment. We fohnd no 23 evidence of any of those inspection reports. Therefore, we. l 24 had confidence in the system that the applicant: was' using ; for documenting-missing components and equipment. l 25

39 1 Our review found that all the equipment required .by the . I 2 hot functional test procedures was either installed .or was 1 3 documented as not'being installed on either a test efficiency! 4 report or a test procedure deviation. Both of these items , I-l 5 the test efficiency report and the test procedure deviation, i 1 l - 6 are the administrative mechanisms that the applicant uses l l 7 for discrepancies found either during the test or before the l 1 8 test. Approximately 95 percent of the test efficiency report's l 9 issued against the hot functional testing documented-' piping I 10 and equipment supports and restraints that were not installed i 11 prior to stant of the test. l 12 We reviewed specifically those applicable test ef ficiency 13 reports, and we also reviewed two test procedure ef fic.ency l 14 reports which had been generated by the conduct of the hot i 15 functional test. We found that the documentation of the . I 16 missine eculprent components was proper and that outstanding l . j 17 testing which remained because the components were not I i 1 i is installed at the tir.c of the test was tracked by the appli- 1 19 cant and his administrative tracking system.
.. i 20 ,ye also concluded that the applicant's decision to ! .;w ,
- 21 proceed with the hot functional test despite the numerous x
' j 22 ePi eces of missing equipment was a_ conscious decision, and it '
l
.23 . appears to have been influenced by . the economic impact of , !
24 delaying the testing program. This:is not unusual. ! 25 We also found that the. applicant at the -time that we l

40 1 did our review was planning a preoperational testing program.' t 2 i That is, they wanted to load fuel and then proceed with'the I I l l 3 tests which were not conducted prior to fuel load. - I guess 4 now this~is up in the air as to whether they will. complete 1 5 all the testing that was not previously done before fuel 1 6 load or whether they will finish some of it and have addi-7 tion'al remaining after fuel. S In any event, any testing that is deferred beyond fuel-9 ing will have to'get NRC approval. 10 MR. HUNNICUTT: The licensee has prepared to do many i 11 hot functional which will cover the items that ::r. Keimig . I 12 has mentioned. They lost a coolant pump that is being
,. 13 replaced right now. Between now and probably the weekend ,
14 they will test'that, and their plan then is to go ahead and 15 complete the hot functional items that are covered here; and 3 16 then prepare at a later date to remove the head and prepare
$ 17 for fuel loading. The number of days is up in the air i 15 because of the pump and, of course, it's the licensee's, . ; 19 schedule.

The pump l 14 had been used a number of times by jogging it to remove air , 15 from the primary system, and they started to do a two-minute 16 test and about 15 seconds they saw a flash of light and 8 l , j 17 smoke and they shut it down and secured all the testing until i 15 they determined the problem.

44 I I I I MR. KEIt'IG : The next concern expressed in CASE-Proposed
- 2 contention 26.was that the applicant did not intend to I 3 check some components in~ the system until heat-up to hot -
4 scandby cr during power escalation. We reviewed that concern 5 by 'looking at the integra'te'd plant operating procedures-- 6 procedure, rather- " Plant Start-up From Cold Shutdown to Hot l l 7 Standby". As in the case for hot functional testing, this 8 procedure specifies that the plant be taken to normal l 9 operating pressure and temperature using reactor coolant l l 10 pumps as the heat source. The system preoperational testing i 11 that was not done prior to the--would not have been done 12 Prior to the fuel loading. At that time, again, this is ; 13 somewhat complicated because of the change in the applicant's! 14 planning now because of the delay in the hearing process. ; 15

But those par-l 5 ticular items do require reactor power in order to conduct 6 the test, so in summarizing our findings on this concern, 1 7 would say that while we found that some of the tests were 8 going to be deferred until after fuel load, we found no. , 9 safety significance with that deferrment process, and that 10 the licensee again had tracked those tests and had done 11 evaluations and, as a matter of fact, has subreitted those i 12 evaluations to NRR for their approval; and if I'm not mis-13 taken, they did receive NRR approval to conduct those tests l 14 after fuel loading. r 15 MR.

And that's what they did, and it's a nice clean 5 l summary sheet in front of the test' procedure that tells you : 6 .w hat this calibration data is, what the serial nuther is, 7 and the instrument is. But as Mr. Keinig indicated, there's I

.S MR. NOONAN: Do you think that from what you've done l . 6 that this thing would have been caught?
7 MR. KEIMIG: It wasn't' a matter of catching it. The

8 applicant reported it in'their summary leak rate test report,
.- 9 in its amendment. It was there. We happened upon it before '
10 the Containment Systems Branch of NRR. got around to reviewing 11 the applicant's report. It would have been picked up. They' 12 were not trying to hide it, as evidenced by the fact that they .
, 13 put it in their report.

, 4 the test, they would have probably been turned down..
I 5 MR. CALVO: Excuse me. When this was subnitted to the . 6 Containment System Branch, it was submitted in amendment to , t
^
7- the pSAR? i 8 MR. KEIMIG: No. It was just in.the test summary report 9 that's required by Appendix J. i l 10 MR. CALVO: It's practice in the NRR to accumulate , i 11 these things that impact the FSAR. At some point in time you 12 write a supplemental safety evaluation report which covers l 13 all these amendments up to *. hat time. If you had not indi-14 cated other ise, that means that you accepted what they had i 15 done ;nd ycu assume they have no great significance that can ^ l 16 l be implied by that. If you feel that it's safety significant, s j 17 then you so indicate it in the supplemental safety evaluation
.i 18 report. It happens to us in the case of the splices. The ; 19 applicant told that to the NRR and NRR has not done the ~
1 g a 20 review up to that time. The TRT requested NRR, "Weneedthel
. l 5 21 evaluation now so we can have a decision on this , matter." j f '
g . 22 They say, "Well,.you precipitated our review. We're not 23

65 g procedure is, how they handle. it, any plants going through i 2 licensing--not Comanch,e Peak, but any plants. l-r 3 I might just mention agairi something that- i 4 first of all, 'we still think that there have been problems 5 in the past with Region 4 's handling of the allegations and e . v. < . - ~ l l e 6 so (orth, and that sometimes .they have not adequately investi,- l i 7 gated;.'but in addition .to that, I think a lot of the problem r , 8 with NRC and whistle-blowers and intervenors has been a lack, t 9 of communication, like what we're doing right now. I think
.l 10 so many times that has been lacking. I want to say again how I
11 much we appreciate all of you taking the time to come talk to, 12 us about this. I think this is a very important part of l 13 what should be going on and should have been going on all the 14 time, not just with this plant but probably with others as , 2 15 well. I think a lot of times it's been--a lot of NRC's s i i 16 problems as far as public perception has been due to lack cf i - g ;_ l communication a lot of times. ; i IS l MR.

'
- i j 20 that was the applicant had committed to perform the test in 4
i l 21
* - rdance with 10CFRSO, App.endix J, which requires the 1 l '- \
l 22 test to be performed in accordance with ANSI Standard, N45.4- l- _ 1972. While the applicant did perform a, test in accordance { 23 . 24' with-that standard, the data computation of the leak rate l

66 1 in accordance with a later Standard, ANSI 56.8, which is l i 2 not endorsed by the :RC. Now, because of the consistency i 3 of the data that was obtained during the test, the calcula-i 4 tional method probably---the calculational method by the [ 5 Standa'rd, Appendix J, requires the applicant to use as j
- . t 6 opposed to the Stan'dard that the applicant did use--probably I 7 doesn't make any difference. As a matter of fact, the - 8 Containment System Branch is also looking at that and has :
9 come to that conclusion, but has asked the applicant to i 10 identify any other deviations from the ANSI N45.4-1972 i 1i Standard that they may have implemented during that test. I 12 MR.

We also I 12 I 13 reviewed the Unit Two acceptance test preoperational testing j4 dated July 18, 1984.. This document provided an index of 15 acceptance tests and preoperational tests including test 16 numbers, revision numbers and procedure titles, and were ,
.i l projected in Unit Two testing program. We compared the i 17 gg Unit Two test index with Regulatory Guide 1.68 and with the ; ; 39 Unit one index and found them to be consistent. Only systeras 20 which are shared by Units one and Two and were fully tested l 21 duSing Unit One testing progpam were not scheduled to be l retested during the Unit Two preoperational test program. ;
i I can 9 1 ve Y u s me examP l es of systems--waste gas, system l 23 control room,. heating and ventilation system, telephone and I i 2a, radio system, and so forth--and the basis for not testing l

3 Unit Two testing program is undertaken, those systems will ; 4 iae in operation. - 5 So we concluded that that concern was without basis. 6 overall, we concluded that there was no information , that surfaced during our ' review of those concerns that would 8 preclude the ASLP from making a decision pursuant to i 9 10CFR50. 57A. We did find sone potential violations, but 10 nothing of any safety significance or with any generic gg implications subject, again, to a review of the findings of 12 the OA team. y 13 MR.

'l took them as being legitimate concerns and did review them.
2 I just wanted to.be clear that all those 3 were' based on the documents that we received f rom the appli-
-4 cant.
5 MR. SMITH: Can I ask.a question? You spoke earlier i 6 about communication. 'I was thinking of that'as I was read-7 ing the area about Unit Two testing. Did you actually e
- 8 receive information that led you to believe that they are 9 not going to test the systems in Unit Two? Did we under-10 stand that properly?
11 I'm not sure. That's one of the things that l 12 I need to go back and look at, our original contention. One ; 13 of the things that I personally was concerned about was that, 14 . they would use it as the basis--since they're asking for = l i l 15 an operating license for both units--that they would use that l 1 16 as a basis for saying go ahead and give us a license for
'I .
j l Unit Two also. In other words, they used the test for Unit i
- 15 !. One whereas they actually hadn't done tests for Unit Two. .,U 19 'Ihat's one of the things that I was concerned about. I don't I - ! 20 remember the exact wording of what was said. That's one of .4 l the things that irar.ediately comes to mind that I remember. l 21 2
g MR. KEIMIG: That's the' way I thought that yo6 'had con ! I strued that. . 6 Also,;you n'ed e to remember, too, that what 2a. we were asking for primarily in this contenti.on was tliat we' !' g
.7
71 1 b wanted discovery abou't these matters; and I think at some ! i 2 point in there we mentioned that we weren't certain. how l t 3 much or the extent of the problems that there might Le, and I 4 we wanted a discovery to try to find that out. In effect,
. 5 what y'all are doing ;is doing some of the discovery on it i 6 now. I'm awfully glad to find out some of these things, and 7 like I said, we'll probably have a few nore questions later. ' l 1
- 8 Within the context of the hearing, it's a little bit 9 different from when you're asking for discovery about a I l
10 contention. It's a little bit different, in other words, l ii from making an allegation like "I went in the field and I i i 12 saw something wrong and this is what it was."
, 13 MS. VIETTI: We went through the various documents, j 14 hearing transcripts, depositions, Office of Investigation 15 reports, old inspection reports that were written by the e
16 Region, trying to get a comprehensive list of technical i i g- concerns, some of which were allegations, sore of ther had l ;
.-}* jS i come out of'other areas that were concerns, and that's how l ,.i 19 we grouped them and gave them to the people in the TRT to i ,

that's not necessarily the case. - - 22 f 23 We were 1 king strictly at their doc,uments l ,

l 8 MR. PHILLEO: That insert thing apparently got you 9 concerned about strengths of concrete in general. In fact, i 10 I think somebody threw you a curve in saying that all the i
;; concrete was designed for 4000 PSI and the actual strength !
t 12 was 4500 to 5000. ,
, 13 That was the applicant. j I
34 ,MR . PHILLEO: Yes, I sensed that. Because, for instance, i 15 y u went through the records and picked out 36 lai,cratory-16 cured standard cylinders that were below 4000. So we went ! 3 I
;_ back and looked at all the mixed designs for all cylinders f
I I 33 that you cited and found that without exception those 36 39 that you pulled out were for a 2500 PSI mixed design. Even

I guess according to the specifications you could 10 interpret that there would have to be some evidence someday gj that the field concrete did acquire a strength of 83 percent of the standard cured cylinders. I think the specifications 12 13 are a little vague on that as, in fact, are the ACI's, the 14 ACI Code f rom which they were taken. 15 As I mentioned, the ACI Code is a building code and + l 16 concentrates on building elements, which is norral bear and i ! I I i 37 column and slab construction, and so it has very conservative i IS requirements for strength that has to be attained by field , 1
'- ; j9 cylinders because it's geared towards fast-track construction i , [ 20 where..they're stripping early and the concrete has to 7, ,
e 21 support itself, and if you back off at all on those early h i i strength requirements, you have collapses as you do, inceec, 22 i 23 g t in some cases. l A substantial amount of the concrete in the project is i 24 l f that sort, but a larger,part is not. They chose to make 25

87 I i 1 all the concrete meet that one rigorous spec, I think, pri- l 2 ) marily because it's easier to build and inspect if you don't] 3 have to decide which concrete meets which class. 4 I have with me the ACI Cold Weather Standard which 5 gives recorrcendations for different types of construction, : i 6 and those recommendations for non-fl.exural members are that- ,i 7 in a climate where they're going to eventually get enough I l 8 heat from the environment to attain full strength where ( l

So it would have been permissible for much of the con- f 13 ! I l 14 crete to be judged that way, just to protect it against l l and - 15 freezing until it's strong enough to withstand freezing, l t 16 i just let it wait until spring and su:rner and pick up the i i l

.a 90 l 1 vague on this point, too. Just to start running through 2 your document here, we'just turned the crank on getting the }
