~ ~mgcl-ll 'l P'R C E E D I li-G S 2 This is-the second deposition of MR. GALLO:

3 Mr. Charles Stokes, being' scheduled in accordance with' d

-the agreement of.the parties, and I think we will refer 5 to'this deposition officially as the second deposition 6

of Mr.. Charles Stokes'.

7 Whereupon, 8' CIIARLES CLEVELAND STOKES, 9 was called as a witness and, having been first duly sworn, 30 was examined and testified as follows:

11

~ MR . GALLO: Mr. Cassel, you have some corrections, 12 or Mr. Wright, do you have some corrections you want to 13 make to the testimony?

73

\-) Id MR. WRIGHT: Yes, we do.

15 EXAMINATION 16 BY MR. WRIGIIT:

17 Turn to page 4 of your prefiled testimony. Do Q

18 you have any corrections to page 4?

19 A Yes, I do.'

20 Q And-what'are those corrections?

21 g -- In roughly the middle of.the top question, it 22 says in myireview, I have reworked a' number of engineering

,. t l

5 mgc -2 calculations. It should state, "In my review, I have 2

reworked aspects of a number of engineering calculations.

MR. GALLO: Wait a minute. I missed that.

4 What line are you talking about on page 4?

5 THE WITNESS: It's roughly the middle of the page.

MR. CASSEL: It's the twelfth line, Jim. We're 7

on page 4, line 12.

THE WITNESS: That should be " aspects of a 9

number of engineering calculations."

BY MR. WRIGHT:

11 Q Now, Mr. Stokes, why are you making these 12 corrections?

'~x A Because the documentation I reviewed, I only 14 had parts of the calculations. I did not have the entire 15 calculation to review, and therefore I only reviewed 16 aspects of the calculations.

I7 Q Okay, Mr. Stokes, do you have any corrections

'8 on page 10 of your prefiled testimony?

'9 A Yes, I do.

20 Q And what are those corrections?

21 A It's the bottom of the second paragraph of 22 question -- or Answer 12. "The result would be an e

1 6-

.f~5. .

' h

I-allowableistress larger than allowe'd by code," rather than 2

"the, higher" --Lit would~be higher, but it's also' clearer.

3 MR. GALLO: Do you want to repeat that d

correction?.

.5 THE WITNESS: "The result would be an-alowable 6

-stress larger than-allowed by code."

I BY HR. WRIGHT:

8 Q Now, Mr. Stokes, why are you making that 9 '

correction?- -

10

.A- Well, the. answer as stated is. correct, but it's II not precise enough. It's more correct with the change 12 that's made.

' I3 Okay. Now, Mr. Stokes, do you have any corrections Q

' Id on page 26?

15 A Yes.

16 0 And.what are those corrections?

17 A Well, after:the 200 -- after the KL/R in the I8 first paragraph, and the 300, the foot and feet should 19 be canceled. Ther200 do's J e not have a units term.

20 MR. GALLO: I didn't understand the correction.

21 Do you want to -~ just tell us what the correction is.

22 THE WITNESS: KL/R is 200, period -- exceeded 9

Vmgcl-4 1 the 200, period. One-'I note'd was 300, period. .

2 MR. GALLO: So you have deleted " feet" from the

'3

-third line, and you've deleted " feet" from the fifth line; -

'd- ~is that it?

5 .THE WITNESS: And " foot" on.the third line at 6 the end.

-7 . MR. GALLO: Oh, okay.

8 BY MR. WRIGHT:

'9 Q- Now, again,.; Mr. Stokes, why have you made. _

10 these corrections?'

11 A As I said,.the factor'is unitless. This section 12 of the testimony was typed up at my direction, but 13 inadvertently overlooked.. It was handled by my attorneys, O 14 and undoubtedly there was a misunderstanding as to that 15 section of the testimony.

f 16 Q Are there any other ' corrections that you have to 17 make to your testimony?.,

18 A , No. c 19 MR. WRIGIIT: Okay, Joe, I think that ends our.

20 portion. s 21 EXAMINATION ,

22 BY MR. GALLO:

23 Q Mr. . Stokes, would you state your full name and v

_  ?,.3 _

~! I

%>.mgcl-5 1 business address for the record?-

2 'A lit's Charles-Cleveland Stokes. As I have stated i '3 earlier, I have no- specific business address. I use my 4 permanent res'idence address:as such -- Route 1, Box 223, S . Cottonwood, Alabama.

6 Q And is the' organization-you are with-called' 7 .P-S Associates?

8 -MR. WRIGHT:' Joe, let me just ask a-question 9 before we proceed with this. A lot of the information 10 we've gone into in'the first deposition, and to that extent, 11 Lit's repetitive, and if we're just seeking a little 12 background information to get us started, I think.that's

,, 13 contained in the first deposition.

k-) 14 If.there's-any othernreason for these questions, 15 I would like some type'of an explanation.

16 MR. GALLO:- Well,- I.just want to affirm that 17 P-S Associates operates out of-the address he just gave me.

18 I don't know if that's in the first deposition or not.

19 MR. WRIGHT: I think it is.

20 MR. GALLO: Well, I'd like to get an answer to 21 the question, in any event.

22 THE WITNESS: The question is if P-S Associates 1

.Q But'is'that the name of'your. organization, that' 5 you're with,'as-indicated in Answer 2 toLyour testimony?

6 A I am a member of P-S Associates, or that is an 7 ' organization which I belong-to,-yes.

8 Q. All right. Well,.'does P-S-Associates have a 9 business address?

10 A No, End-l 11- Q' Your testimony says.that you graduated _from 12 Auburn University,in 1975 with a BCE degree. What do

~

13 -those letters stand.for?. '

.O 14 A Bachelor of Civil Engineering.

15 0.' Was that a.four-year curriculum at Auburn?

16 .A It' was. ,

17 0 And..if-<I. understand your testimony, this is your 18 only engineering degree?

19 A It is.

20 Q Did you take any course work at Auburn in the 21 field of structural dynamics?

22 A I did.

[( k/mgc2-1

..1 :Q What was that.. course work?

2 A I took structural mechanics, dynamics, strength

- 3 - of' materials, stedl-design, concrete design;--

4 ~Q _ Wait-a minute. Wait a minute. You're going too

. 'S fast.

6 ~ You say you took' structural dynamics? '

7 MR. .CASSEL: No. Ile said structural mechanics.

8 Then_'he said' dynamics.

9 BY MR. GALLO:

10 0 ' I'm sorry I interrupted you, but go a little 11- slower. ,

12 A Structural mechanLics," dynamics, as an ME. course.

13 Q.-,

Okay.

14 A' Strength f materials. 'Three different courses 15 in structural analysis. One of the final courses in that t6 area was structural analysis. The first two were subparts 17 of structural analysis.

18 Q Can you remember what those were?

19 A Not specifically, no. They were involved with 20 - structural design, but leading up to structural analysis 21 as a whole, and then structural steel design, concrete 22 design, foundation design as a structure, and I consider a

11 I

' #mgc2-2 ' course which might be-excluded from structures per se, 2

but applicable to structures, soi]' analysis and a soil 3

stabilization' course.

-Q Now'I take it.that these are the names of 5

individual courses that you took while you were enrolled.

6 in Engineering School at Auburn; is that correct?

7 A. Yes, the three-that I listed as a group in 8

structural analysis, I didn't break down to names, but the rest of the course names per se.

30 Q. But you are telling me that in the structural

' analysis area, you took three courses, the last being 12 structural analysis? ,

I3 A' Yes.' '

'd Q Now you say you took a course called " Dynamics,"

15 and what did that involve?

16 A It was an ME course in dynamic loading, dynamic 37 forces and the use of those forces in calculations and 18 stresses.

~

I' O And involving what design?

20

.A Anything -- structural, aerospace, any mechanical 21 component, machinery -- any item.

3 ~Q Mechanical dynamics?.  ;

4 A. -Yes.

5 .0 Did you take any course work .in seismic analysis?-

'6 -A No.

7 Q Now I've_got a series of questions I want to ask.

8 .you about your work experience.

9 Based ~on'my-review of.your testimony, it appears .

that-you worked 'for two and a half years as a draftsman

~

10

!. .i~

i 11 and detailer'for-Southern Servi,ces;'is,that correct? ,

g . . .

12 'MR.' WRIGHT: Obj dction~. Joe', this is the T

13 second part of the' testimony.- In the first part, these

.O 14 questions were asked and answered, and that's the basis of 15 my objection.

16 MR. GALLO: Okay. Objection noted.

17 MR. CASSEL: Well, I-think we may go farther than 18 that, Joe. Is there a need to go -- you know, this 19 material -- his resume was available at the first l

20 deposition. All these things were listed. I forget whether 21 it was you or !!ike that asked this series of questions 22 about this whole area.

f' i

I O

I-

13 i

r^x t l

-4 mgc2 1 MR. GALLO: Well, the1 resume was made available 2

just prior to the deposition starting last time.

3 Mike' Miller took the. deposition, and it was an illegible d ~

copy-for the most part. I don't recall that these 5

questions were' asked just in the way I am'about to ask 6

them. In any event, I want to ask them, unless you are.

7 going to instruct the witness not to answer them.

8 You can object on whatever grounds you see fit, 9 but I want.to ask the questions, and-I expect answers. -

i

, 3 10 A Well, IlmayLwant to instruct the

, MR.lCASSEL:

~

II witness not to go over again the same ground that was gone 12

-over before. It's unusual, as you know, to make a witness 13 r- available for a second deposition in a case. We are doing i

N- y4 it here, because he now has prefiled testimony.

15 MR. GALLO: Well, I guess we're going to get-in 16 an argument , then. What do you mean, it's unusual, 17 because the unusual circumstances stem from.the fact that la you weren't prepared and able to go forward at the time 19 the schedule was set by the Board, due to the fact that 20 you just couldn't get your witnesses together and-get it 21 done. The understanding was that we would have a second 22 deposition; isn't that right?

f. :'

f 14

- A

() 'mgc2-5'1- -MR'.lCASSEL: The understanding ~was:that we would 2 makeshimEavailable for a second deposition,, based on his 3 prefiled testimony, which~was the reason.--

4 MR. GALLO: 'And I am'asking questions from-his 5 prefiled testimony.- ,

.'4 6 I'm sorry. Go ahead.

7  : MR. CASSEL;. If you have-a particular area or-l >[

~ t c

=

8 point that'you think was'not sufficiently addressed in-9 the first deposition - we. don't want to be unreasonable, to but I don't $hink any of us want to sit here and spend the 11 .same two hours that Mike spent the first time.

12 To the extent that resume was-illegible,

, 13 Charles explained the answers in the first deposition.

'~ I4 MR. GALLO: Well, be that as it may,-these are 15 the questions I want to ask and as I believe it's 16 appropriate to ask them, and you will just have to take 17- whatever action you think is necessary.

18 MR. CASSEL: Well, let me tell you what our 19 position is. Our position is, if you can give us a 20 particular reasons why you need to go over this same 21 territory again, a particulhr line of inquiry you want

.22 to pursue that wasn't pursued before, we'll entertain that.

' ; m'gc2-6 But otherwise we will instruct the witness not to answer a whole' series of questions about his resume, which was 3

. extensively answer.ed in the.las't deposition.

d 2 Mii. GALLOi .:Well, I don't-think I'have to S

justify ~'and; establish a reason why I want to conduct this ,

6 line. Iithink'is s an;appropri te'line, and I. intend

~

7 to ask the questions.

8 MR'.'CASSEL: Well, I'm' telling you right now,

~

we will. instruct the witness not to answer any questions .

IU

'about his work background, unless you can state a II specific reason how this goes beyond the first deposition 12 or --

I3 MR. GALLO: I don't have that burden. You have 14 that burden. My recollection is, I have a. question here, 15 "What is a detailer?" That question wasn't asked, and to y,m about to ask it.

I7 MR. CASSEL: All right. Well, we'll listen to

'8 them one by one.

I9 MR. GALLO: All right.

20 BY MR. GALLO:

21 0 Let me start again with the question prior to 22 tha,t , time. -- am I reading your testimony correctly,.

V O

c ' '

s .

16 T._/ ~iA m g2 7- 1 Mr. . Stokes'-- that you worked for two and.a half years 2 for Southern. Services as a draftsman and detailer,

3. .approximately?- '

4 MR. CASSEL: I am going to. object to that

^

l .

S question;and1 instruct the.Nitness notx to answer that. That 6 was'specifically asked andl answered at the last deposition.

~

7 MR.'GALLO:' You:are instructing the witness-8 not to answer?'

9 MR. CASSEL:. That's right.

10 BY MR. GALLO:

11 0' .Mr. Stokes, what is a detailer?1 12 'A A detailer is one who has responsibility for

~

13 doing certain aspects of a design. He does do design O' 14 work, but he's a member of the drafting department.

15 Typically he would be considered a designer in the drafting 16 department, rather than a draftsman.

17 0 Do I understand, then, a detailer is a higher 18 level of competence than~a draftsman in the order at 19 Southern Services?

20 A Yes.

21 0 All right. So the draftsman, then -- what 22 .

were your duties as a draftsman for Southern Services?

O

W 17 k-/.m gc2-8 1 A Well,.as a' draftsman, I did neat line 2 reinforcing drawings ~for concrete, neat line drawings for 3 structsral steel.', I did,the rebar takeoffs, figured the i .i .

4 splice lengths" required for embedment, and I'did do some 5

detailing as a;draftsperson,.-in that I detailed rebar s

6 around' openings, expansions. I detailed molded Connections.

7' Q All right. I'm sorry tc interrupt, but I want  ;

8 to try to get the record clear.

9 My question was limited to draftsman. I'm 10 going to ask you about detailing, but I have some 11 follow-up questions about your duties as a draftsman, 12 based on the terms you just used in your answer.

13 When you said you did neat line drawings for 14 concrete and structural steel, what does " neat line 15 drawing" mean?

16 A It's the line diagram showing the extremities 17 of the concrete in the poured condition, locations of 18 openings. It shows embedded items, placements, locations, 19 the item numbers, the slope on the concrete for drainage.

20 0 These are all noted on the drawings?

21 A Yes.

22 O What kind of drawings would these be?

~ 18 s

1

. ,=3 -

mgc2-9 I Jh Neat l'ine. drawings.

2 0 hey 1are called neat line drawings?

3

- A The specific title.

~ ' w 4

Q And'what are,they u5ed for?

5 A Building the rebarsupporting_ structures, forming 6

the' concrete, decking the pit if it's below ground, grading 7

for pouring the concrete, all --

a 0- And what are rebar takeoffs?

,A A rebar takeoff is a listing of~the steel'

'O straight lengths, bent pieces, the necessary pins Il

" required to form the piece. It lists the tonnage, the 12

sizes of steel, the tonnage per size. It may list a 33 few other items, but that's basically it -- the strength-Id of the' steel required in'the rebar.

15 0 What kind of structures were involved with these 16 particular drawings that you were working on?

17 A I worked on both fossil facilities and nuclear

'8

< facilities -- neat line drawings and robar drawings, l'

O Can you be a little more specific as to what 20 elements of these facilities you were involved with in 21 this work? Take the fossil first.

22 A Well, over the timeframe that I was doing this I

2

~

- . .g. Wh'at is Miller?
3 A -It's the" Miller steam plant. It's.a fossil
d. . plant. It's called Miller steam plant, but it's a fossil 5 - plant.

~

6 I worked on pool boxes, miscellaneous outdoor- ,

7 structures on'Farley nuclear. plant.

8 Can you identify one of those structures for me?

O ,

9 :You' called'it an outdoor structure. ,

30 A Well, one of the type things I' worked on was 11 the pumproom, the box. It was --

12 The pumproom box?

Q 13 A Yes.

O Id 0 Did this involve safety-related equipment, do 15 you know?

l 16 A Yes, it did.

i i End 2 17 0 Explain to me the difference, then, between 18 a draftsman and a detailer.

19 A Well, a draftsman typically may do some detail

20 functions, whereas a detailer, that's classified'a 21 detailer, specifically does nothing but detail functions.

22 Our designers at Southern Services when I was r- ,

.t i  ; . .

fT

'sSgc3-1 I there were primarily responsible for doing detailing. But 2

as a draftsperson, . I was not just a draftsperson, in that 3

I was there as a co-op, and engineer co-op, and so I was d

allowed to do detailing functions that normally.the 5

designer would do as training in the co-op funct' ion.

6 0 Can you explain to me what that program was?

7 I am referring to the engineer co-op program.

8 A The program is set up, allows.a student to attend college one semester or one quarter and then work 10 with the company. The work in the company is geared towards 33 what he will be doing upon his completion. In other words, 12

-he'll be working in the same aspect as his degree would 13 be -- civil engineering. It would be in functions -- the

'd duties he would be assigned would be functions that would 15 be important to make that person, that graduate, a better 16 engineer upon graduation, knowing what should go in a 17 drawing, neat line, reinforcing, how to detail rebar, is detail molded connections, draft a document - necessary

'9 training for an engineer after graduation, in that if he 20 was to review that document, he should first have done it 21 to know what was on it.

22 The tasks varied from semester to semester. As I O

7. '

. ' n) 1 , ,

.I

'mgc3-2 said, every'other semester I was in school, and every other 2 semester I was'at work. I was rotated around-the various 3 departments from the concreta fossil, structural' steel

, c d

' department, to nuclear concrete and nuclear steel department.

5 - That's the way Southern Services is set up.

6 So if I understand your testimony, you worked

-Q

- 7' one semester and didn't go to school and then went to l.

8 school the next semester-but didn't work?

9 Did I understand that correctly?

10 A I didn't go to school, but I was going to school 11 for my degree, and while-I was co-oping I took courses 12 l at Birmingham, the University of Birmingham, an extension r

13 of Alabama, at night.

Id 0 Were these engineering courses?

15 A yes, l

16 0 Well, just for my information, when did you then 37 first enroll at Auburn?

18 A I transferred to Auburn in the fall of --- let's 39 see, I believe I went in early -- the fall of '70.

20 I would have to look back at records. I attended a l

Q .How many years were you there?

'd

~A It's more like quarters,-but roughly four,.I 5

think.

6 0 Four: quarters?

7

.A Yes.

8 ~

Q Then you transferred to Auburn from out of'that school?

IO A Yes.

'I

'O Did you transfer directly into the Auburn 12 Engineering School?

13 A No, I didn't.  !

14 0 Can you explain why not?

15 A Well, when I first started college, I started to in aerospace engineering. The aerospace had roughly 37 20,000 men laid off one year after I was in school. I also is was sick. It changed my aspects toward life and what I l'

felt I wanted to do with my life.

20 I attended a drafting department course at 21 George C. Wallace for six months. As a result, I decided 22 I'd'be an architect. I transferred to Auburn in the r

a i

F 1 23 l l

- mgc3-4 1 architectural department. In the late fall of '70 or '71, 2 I'm not sure.

3 I see. So you essentially started out afresh Q

4 in either the fall of '70 or '71 at Auburn, is that it?

5 A Not exactly. All the course work I had taken 6 for aerospace was more atvanced than the course work for i

7 the architectural department. The courses applied, though, 8 in the case of technical electives in the architectural 9 curriculum, and what that did was it upset my schedule.

10 and to counter that upset, I took courses in the building 11 technology curriculum and was working on a double degree.

12 Q I see. Now after you graduated in May of '75, 13 you became an assistant engineer at Southern Services; 7s

( I

14 is that correct?

15 A yes.

1,6 Q Your testimony indicates that you designed 17 outdoor structures on the Miller steam plant. What were 18 those outdoor structures?

19 A Right after I graduated, I worked on the ash 20 trench system, which was a system of structures. It was 21 primarily a trench, concrete canal. It also involved 22 road structures which were in compliance with ASSIIO.

11 A Yes. And I think the federal government f

12 requirements were met. t

( '

13' - O All right. I'm sorry I interrupted you. You O 14 said t!!at you were involved in the design of a concreto 7

15 canal trench system and road work?

16 A Yes,-the road work. I also did piers and i 3

17 abuttments for a pipe bridge that spanned a creek. I did is the concrete piers and abuttments for a bridge for trucks  :.

19 which. carried wet fly-ash to the storage pond or damp 20 area. I basically handled structures at various locations  !

21 along the piping system from that point on to the storage 22 facility, supporting structures, kick blocks for that '

a without making a very sharp turn.

P 9 I worked on makeup water lines offsite, thrust ,

10 blocks, cut-and-fill drainage, and other things. There 11 was many other things I did.

i 12 Q Let's return to the concrete canal or trench 13 system. What exactly were your design responsibilities O 14 there?

15 A It was designed to withstand side loading from 16 soil and water pressure, large cranes sitting next to 1/ this structure, surcharge from trucks, because many of the I 18 canals ran right next to the road structures. On top of 19 that, it was designed for these large soil-moving machinery ,

5 A To ensure that components were within. code o allowables.

7 And is the component we're talking about the Q

8 baseplate?

9 A It was primarily geared to the baseplates, but 10 as I said, we redid the entire structure for this work.

11 Q When you use the term " entire structure," what 12 are you talking-about?

13 A It covered every component from the point of

14

-attachment to the pipe down to the plate and the bolts.

15 We reverified the entire structure. The attachment 16 hardware that was purchased was reverified. The load 17- capacity, the stiffness, the flexibility of the system 18 was reverified in com'plete, in effect, in performing 19 these calculations, which were:specifically bolts.and 20 . plates. We' redid the entire work that had been done.-

3- A- 'The stuff'I worked on was containment,-main 4 steam, all over'the auxiliary building. Predominantly 5 all I worked on was containment. A lot of this stuff 6 was Westinghouse's original scope that we redid ourselves.

7 Westinghouse kept the whip restraints. I don't remember 8 wo'rking on any whip restraints during that time, although 9 I think. I did do some field work for Westinghouse as-to H) determining-whether or not something would workifor~them.

11~ What was the purpose of these baseplates?

Q I2 A Baseplates were the transferring load mechanism 13 between the structure and the bolts to the concrete Id structure or supporting structure.

15 Q So on the one end you had the building structure 16 Were the embedded;in the and at-the other, the baseplates.

17 concrete for the building structure; is that it?

l 18 A The ones thht were embedded in concrete were

' 19 not part of this program. 79-02 limite'd the work'to those 20 with expansion type anchors,'I believe.

7

.O What component sits on th'e baseplate, if any?

8 A The structure that's~ attached to the-plate, 9

small-bore, large-bore piping systems, HVAC, electrical

. 10 conduit structures. Primarily.this work that I worked on I

here was all~large and small-bore piping systems.

12 Q. All right. I guess that was the source of'the 13 p confusion. When you use the term " structure," you are Q '#

referring to both the building and the equipment components; 15 is that right?

16 A It i~s'both;the-structures, yes. One is --- I 17 l use structure," if it's the overall building structure 18 as a structure,;and'I use " piping' su'pport structure" as

'9 a struc'ure.

t HVAC supporting steel is a structure and 20 electrical conduit supporting ~st' eel, all the way including

-# mgc4 Q Now what'did you do, what type of analysis did 2

you preform under I&E Bulletin'79-02?

3 A. Well, they were mixed. Both functions-were-

_ performed at the same time. I verified that the anchor 5

bolts were acceptable, that the loads being transferred 6-to them through these plates from'_the structure. I verified 7 ^

that the concrete could take the load'from these anchor 8

bolts.

9 Q All right. You testified that you redesigned

'O the precipitators structural steel on the Miller steam- ,

' plant. Can you tell me what a precipitator is?

12 A Well, I said when I was co-op,.I worked onuthe I3' ash trench system. That system primarily originated from Id the precipitator.- The precipitator is an electrostatic 15 precipitator'.s -All the smoke and exhaust from the plant 16 went through' the precipitators before going to the stacks.

'7 The precipitators electrost'atically removed the fly-ash

~

18 particulates down to a certain criteria. It'was rinsed or 4

'9 transferred'to water, a slurry system, which was actually 20 pumped from the precipitator area out to the storage 21

- facility. It's a very large machine, very large.

you explain'to me what_thoseLaspects were?-

3 A Well, basically like I said, the;precipitator is-

-4 I'll give you some dimensions.

a large structure. It's-5 maybe 400 feet' tall. It's 400 feet high, 200 wide, 400.long.

6 It's large enough'for a football field, roughly. The

'7 structural steel then is like a very large building. It's 8 built to enclose all the equipment and support it for 9 this --

10 Q- That's all right. Did you do the design work' 31 for the structural steel?

12 A The initial design work was done by someone else.

13 Q And w' hat' design work'did you do?

' 14 A Well, when'I~was assigned to the project, they 15 wanted to enclose the roof. >They. wanted:to put a crane 16 on top'of the'roo'f to remove cert'ain very heavy objects.

17 They didn' t.want- to bring around one of these 'oig- boom 18 cranes to lift things off every time, and so they-were 39 wanting to add a crane on it. fly job was to redo the 20 structural steel analysis for the frame to determine the 21 loads from this new support, the new structure, to design 22 it for the' wind loads at the plant. It had to be designed p.-

- steel asfit? heated.up to nearly 500 degrees or higher, 3

-and atLthefsame time.I'had to determine the. locations on d

7 There was no' structural steel there.

8: And I had to-' review the precipitator drawings 9 to determine where it could support the loads I was 10  ; talking:about putting on it. I spent some time in doing 11 that analysis.

^

12 g: What code didjyou-design to?

13 A The structural. steel was designed to the AISC

.O. . 14 Code.- STRUDL was used, asfhad.neeh,us'ed in the original

~

J , ,%.

15 analysis. The STRUDL design code check was used to-16 facilitate verifying.that each; member was capable of taking 17 the stresses. In STRUDL, the termal loads from the 18 expansion were used to force the frame to stretch. It1wasL 19- used on the analysis of the roof to force the side members 20 to expand outward against the bolts"which were attached 21 to the precipitator.

22 The reason for-it was the precipitator grew out,-

3 It. displaced the frame, and the frame was verified for 4 the loads, and'the connections were designed to take thato

'S load component at the precipitator location.

6 Q STRUDL is S T R U D L (sp'elling) ?

7 _A. Yes.

9 A Yes.

12 A -.Yes.

,, 13 Q Were you involved in the, development of the 14 computer code?

15 A No .-

16 Q This design analysis for the structural steel 17 on the precipitator that you performed, did it involve is any seismic analysis that you performed?

pg A Not on the precipitator at Miller, no.

20 Q_ You also testified that you performed some-design 21 work involving structural steel of the coal conveyors 22 for a fossil plant called Scherer, SCHERER (spelling).

_ i 'Can you explain to me what your design 2 responsibilities were in that effort?

.3 A To' design the structural steel again.. It was a

.4 conveyor system that'went from the building, which was 5 . roughly a couple of hundred. feet off the ground level.- The 6 system went from that grade, transferred - .it was a slope 7 -structure, went down to grade. It was a series of. vents e and towers in between to support the ends of these frames.

9 It, too, was enclosed. .

10 Q Was STRUDL used on that work?

11 A- <

No, it wasn't.

12 0 .Was' any computer- code: used for assistance in that m . 13 work?

14 A Not'in the steel design, no.

15 Q Did the steel design for this conveyor involve 16 any seismic analysis?

17 A Not on the fosil plant; no, it didn't .

la Q Then your testimony indicates that you left 19 Southern Services in May 1980, and you went to work for-20 Bechtel. And you testimony indicates that you performed 21 analyses for Bechtel. Again, they're called 79-02'and 22 79-14 analyses.

-I-assume -- and correct me, if I'm wrong -- that 2 these are the same as the ones we just' finished discussing 3 thas you performed with Southern Services; is that correct?

4 A They were similar in the respect that they were 5 79-02'and'79-14, but Bechtel had their.own requirements 6

for meeting those bulletins, which differed,from the 7'

requirements of Southern Services, so they were different.

8 Q But theLI&E Bulletins were the same.

9

.A, Yes.

10 Now as-I understand-your testimony, you left Q .

II Bechts1~in October of '80, and as I understand'it, you 12 went to work for Nuclear Services then; is that correct?

13 A Yes.' That's --

Id You indicate that you-worked on Zimmer. What Q

15 was the nature of your work on Zimmer?

16 A Reverification, I believe, primarily. The 17 structure was already there. We reanalyzed the entire 18 structure, the pipe supports.

19 Q You're going to have to help now. What kind 20 of structures?

21 A Pipe-supports, the work that-Quadrex was working 22 on for Sargent & Lundy was geared to the small-bore piping

37 i 3-

'/ mge4-10 1 systems predominantly. There was some large-bore worke 2

given to us to do.

3 I also did pipe stress calculations in relation 4

to that work.

5 Now we're talking Zimmer, right?

Q 6 A I was -- Well, Quadrex, in the office, Yes.

7 they had decided,tofform a special team that could do pipe 8 stress and pipe support calculations to resolve several 9 systems.in the field.- It s'eemed several lines had been 10 run at some distance from any supporting structure, and 11 it was very. difficult for the stress group to decide where 12 to put supporting steel, because they primarily didn't have 13 hanger background, and in any case, I was part of the g~ ., .

() _

14 special team that was taught in-house pipe support and 15 pipe stress design and then sent to the field.

16 Q I see. Now you have to bear with me because 17 I don't understand this engineering analysis very well.

18 When you did these small-bore piping and pipe 19 stress analyses, just how did you perform these 20 calculations? Did you develop the loads, or were those 21 loads given to you by someone else? I'm trying to pinpoint 22 just exactly what your responsibility was.

N.

( l v

38' l

ex

~k-<' mgc'4-11 -l' A. Well~, the. loads' were determined in relation to 2 the pipe supports by a stress group. Now the group thats 3

did that'for us in the work we were doing on Zimmer at 4 Later, I became sort Quadrex was.another Quadrex group.

5 :of a part of that group and part of the' pipe stress group.

THE WITNESS: Well, there:was a mechanical-15 designer who'~did basic layouts for the components.

the component shapes.

.2 BElMR.-GALLO:

3 Q Did you define those loads, or were they given d

to you by.some other group?'

5 A. I defined those-loads predominantly. I was given 6

the magnitude of the electrical ' field that would be 7

~

exerted on them by the Electrical Department. The Physics 8

Department specified certain other criteria that they had 9

to comply with, but I generated the loads myself.

30 Q And did you generate the seismic loads.yourself, II too?

12 A Yes, I3 How did you do that?

Q O Id MR. CASSEL: Are we getting into a confidential 35 area with that question?

16 THE WITNESS: No. It's a UBC, at the University 17 of California --

IO MR. GALLO: I would like to state for the record I'

that it's my belief that what we're talking about is a 20 part of the Department of Energy's high-energy physics 21 program, which is unclassified, and the only thing one has 22 to concern oneself about is whether or not it involves

4 MR. CASSEL: I have no reason to agree or disagree 5 with your belief, Joe. I'm not familiar with the program.

6 I'm only concerned that I want the witness to be very 7 careful that he doesn't go beyond any agreement that he may 8 have signed, whether it's based on proprietary or security 9 or whatever. He's not charged with knowing what the basis 10 for the agreement was.

11 MR. GALLO: Let's establish that for the record.

14 LLL?

15 A I think I signed some when I started at LLL.

16 Q What was the nature of the agreement?

17 A It had to do with drawings, calculations, 18 references to this instrument. No removal, taking nothing 19 with me. I don't believe I -- I'm not sure if it stated 20 I shouldn't discuss it.

9 I don't think they'd want; Russia knowing how they built 10 theirs, if that's what you mean. I think that's confidential, il yes.

12 Q Well, Mr. Stokes, do you or do you not know 13 whether the work you were involved with was classified?

O 14 I submit to you that --

15 A It wasn't classified as top security classified, 16 if that's what you re getting at.

37 didLit have a load value that you took out of the code-18 and used.in your analyses?

.Q 10 y'ou.went to work for Reactors Control,* Incorporated.

" 11

'According to.your' testimony, you worked on control rod 12 design systems'for Grand Gulf.

o 13 MR. CASSEL: Control rod drive systems, I think Id it says, Joe, not design systems.

15 MR. GALLO: You're correct. Let me restate the 16 question.

I7 BY MR. GALLO:

18 Q What was the nature of your work with respect 19 to the control-rod drive system that you'workedeon at1 Grand:

20 Gulf?

21 g .I was hired as an~ interface between the Hanger 22 Group, which .was handling the -- the Hanger Group was RCI.

. 7 D

O s

49

,-n _

' # mgc5210

' 1

.They.had in-house personnel doing hangers. . I was an 2 . interface with the Piping Analysis' Group, which was being 3 done -- or I was contracted to a firm that all I know is d I was hired to perform' field functions by an acronym, ECHO.

5 for those two groups, and primarily to interface b'etween 6 the two groups as to whether'or not'a support could or 7 could not be built at'a location as affecting stress to a the pipe and as to whether or not, from a hanger analysis 9 approach, could or could not be built.

10 My background in both stress and supports was 11 the primary reason for me being given that position. I 12 resolved problems when Stress requested a hanger that 13 couldn't go where they wanted it because of hang'er

,f-b 14 configuration problems, by suggesting different locations, 115 based on my stress analysis background,.which would be 16 accepted on a point-blank basis.

t 17 4- I was responsible for verifying the system's 18 flexibility, that the surge from the pressure suppression 19 pool, deflection of.the slab it sat on, could be taken i

20 without jeopardizing the system.

21 I was responsible for verification that there 22 is no non-safety-related system or component within the l

vicinityyaf_those Class I lines which would inte'rfere 2 ~

with that'line in a seismicJevent. I basically was like 3

the mother to-that system. I did a lot of: things to ensure 4

its. integrity.-

Q Now if I.' understand what you just told me, 6

you a re talking about supports for piping systems; is that 7

correct?

8

'A It's'the_ control rods,~their piping systems.

9 They're three-quarter, one, two-inch lines, inch and a half-

'IO lines that control the drive-line's. I don't remember if

" they-have water or air. It seems like they were water-12 filled. Water was used as the hydraulic medium in that 13 plant.

O Id Q And these piping systems, are they located inside D

containment?

16 A Yes.

17 Q And if I understand your function, if a support, ,

  • I8 piping support, was required to be installed at a certain-19 location and there was something in the way, an 20 obstruction, and it couldn't be located there, then it was 21 your job to make a recommendat' ion as to where it might be 22 '

BU3 located?

g

51 J w

'A '~] ' mgc 5 1 A Th'at was one:of my functions.

2 O How did you go about making that determination?

3 A I relied 1on the years I've spent in engineering,

'd

.the. training,.the knowledgeI I've gained.

5-0 Did you conduct any kind of analysis to determine 6

.that~you'had selected the right location?

7 ~

A It was based.primarily-onfexperience, background 8

knowledge of the system operation. I basically -- basically pipe systems are an intuitive analysis approach. If 10 you've got a restraint on'one-end,-the pipe is thermally II growing somewhere, it has to grow to the other end. If 12 it's restrained on two ends, you have to have sufficient I3 r offset'to allow it to-deflect at both locations.

D] Id There's many aspects--to making that kind of a 15 determination, but basically it was walking the system 16 down, looking at it, looking at h'ow it was restrained, 37 looking at its attributes, how it was designed initially,

'8 getting a feel for how it moved when it's heated cnr

" exposed to certain load displacements of certain types, 20 and then making a decision.. And they wanted someone who 21 had enought experience to make that decision and suggest i' that location andLnot:have it turned down, not have to do i

10 A- Yes.

11 Q Now you indicated to me that aside from siting

~2 1 these hangers or pipe: supports, you did other things while

' 13 you were involved with the control rod-drive system at

.O 14 Grand Gulf. What was another thing?

15 A We walked the existing support structures down, 16 as-built them, sent those back to the home office for 17 computer input code generation, verified- span lengths 18- between supports. I walked the system. We verified the 4

19 system and documented it.

5' and sent1those to your.home-office?

6 1 Yes.

[End'5- 7- Q Did.you have any other job responsibilities 8 besides the two we just mentioned?

9 A I worked with the Hanger Group in suggesting: 'that-10 certain loads'be placed on different hangers, by requesting- -

11 that Stress not hang a support in a certain location.

12- I also assisted the Hanger Group in suggesting 13 ways' of design that they could do in the field, based

- 3

14 on constraints of construction which-the office wasn't 15 knowledgeable of.

16 I generated ECNs eventually, Engineering Change 17 Not' ices, modifying the structural steel on the supports to 18 the configurations necessary to comply with both the ,

19 2 Stress Group requirements and Hanger requirements, and they 20 were issued from..the field' and,I worked with the 21 Construction Department, because in many cases some of the 22 stuff'we wantedcto do, I had to'get their inputs because a-b

it would not exceed the FSAR-requirements nor change any 8

13 A Yes.

said, in this document in your testimony. I have a series 16 of questions with respect to those. .

17 On page 9, what you identify as Point 1, you I8 refer to a mistake that occurs in the formula, Section 12.2.4.

39 Can you tell me what type of design work is-covered by .

20 Section 12.2.4?

21 A Yes. The area is subgrade walls in structures.

11 Q And to your knowledge, you_just don't know who 12 did this work; is that correct?

17 0 All right. Turning the page, you refer in is Answer 12 to Section 19.5.d. Do you know what design 19 work this particular section concerns?

20 MR. CASSEL: Objection. It's answered right 21 there in the answer, to the extent the witness knows.

1 AFTERNOON SESSION

.2 .(1:10 p.m.)

'3' Whereupon, 4 CHARLES CLEVELAND. STOKES ,

5 resumed the stand and,'having been previously duly 1 sworn, 6 was examined and testified further as follows:

7 EXAMINATION - (CONTINUED) 8 BY MR. GALLO:

9 0 Mr.~ Stokes, referring to Answer 15, does 10 Section 34.2 deal with the general subject of the 11 installation'of embedded plates?

12- A I'm not sure if that's the overall topic for 34.

13 1 would assume it was,-the way the rest of the document

' - 14 was structured.

15 0 All right. What are these plates embedded in?~

- 16 A The plates are not embedded. They're -- well, 17 they're recessed in concrete when it's potted. The 18 attachments on the back of the plate are embedded in 19 the concrete. Studs are embedded in concrete.

20 0 What are the plates used for?

21 A Attaching various components in the plant to 22 the foundation.

Q t

~- ,

8 v )

72

.y_

. x,) mgc8-2 i Q- Do you know what contractor installed these 2 plates at the Byron site?

3_ A- No,,I don't.

4 Q In your-Answer No. 17, you say that you saw a 5

12-inch'line that had a strut to the embed plate on the 6 wall. Can you tell me 'what 12-inch line you are' referring 7 to?.

8 A 'This'was the Saturday that_I come in to the NRC 9 Judges, and it was -- we' stopped at this location, and to it was pointed out and discussed in thorough detail. 'I ti attempted to write down the line number, and I did write 12 down a number, but I don't believe I have it with me. I 13 didn't put it in the statement because I felt it was

- 14 obvious to enough people that were present that-day that 15 I wouldn't have to have it, and I'm not sure the num'er 16 I had would be valid for the line anyway.

17 Q Do you know what kind of line it was?

18 A I don't remember what system it was on, no.

pp Q Where was it in the plant?

20 A You're asking the wrong person. I wasn't leading 21 the trip. It was in the auxiliary building, I believe, 22 but not having a lot of familiarity with the plant, I couldn't

~

.. y i

_ _ _ _ _ , . . _ _ _ ._ _ ~

73 Omgc8-3 1 say, because I wasn't -- I was led, so to speak, to the 2 point, and that's all I can say.

3 What type of strut was it?

Q 4

A I don't know who made it, if that's what you mean.

5 Just a steel beam?

Q 6 A Well, it was made out of a combination of pipe, 7

a couple of swivel connections, a threaded section, some 8 nuts, I believe. There was a pipe clamp, an end bracket 9 for attaching it to the steel, a pin.

30 You say in your Answer 17, in the third sentence, Q

11 you' indicate that if there were a large load on the strut, 12 then you could conceive of a problem.

<. 13 Do you know whether or not there was, in fact, 14 a large load calculated for that particular strut?

15 A No, I don't. I base that statement on the fact to that the large strut would not have been required, had it 17 not been such a large load. They could have used a much 18 smaller strut to take the load, and I based it on my 19 previous knowledge of how large the strut was and the 20 load ratings for various components, and estimated the 21 load for that structure based on that.

22 You say you estimated the loading for that O

\

n.

s.

74 1

' . LL ~ mgc8-4 1

structure?

'2 A 'ye3, 3

0 'And what was that estimate? 15 to 20 kips?

4 A Yes. I would guess the load would have been 5 that magnitude or more.

6 And this observation is based solely on your Q

7

~

~ visual observation of this strut?

8 A That and-the pipe, how big the pipe was and the 9- location to the elbow which was very close'by. Various 10

~

factors. But I was very -- I tried to be on the ,

4 11 conservative side of that estimate.-

12 0 Did you see other examples such as this when-13 .you toured the plant?

14 A I didn't actually get to tour the plant in the 15 way that.I like to say it, and for that reason, I didn't 16 see any more on the tour that I was on that day, no.

17 I'd like to add a few lines to that. The tour is was~a quite fast-paced tour, just watching where I was 39 walking and trying to keep up with the group required my 20 utmost attention. I tried to get the tour slowed down, 21 so that I could actually sort of stroll along and look 22 outside of along where I was standing. That was not

- . ~ ,

n' s

75 v./ mgc8-5 'i c 'possible.

2- ;It appeared-that the tour was structured more 3 -for the Judges, and that they wanted to keep it.at a very 4 fast _ pace for them.- For that reason, I didn't see any more.

~

5 Q The tour-that you're referring to is the one that 6 the Judges requested be conducted for them during the 7 hearings.at the last session?

8 A Yes.

9 Let's assume that your visual observation is Q_

10 correct, that the load on this particular strut and baseplate 11 appears to be 15 to 20 kips. Do you know whether or not 12 that particular strut and baseplate -- embed plate, I should 13 say -- could withstand the safe shutdown earthquake for

'O 14 Byron at the load that you. estimated?

15 A On my past experience, if that's the load, the 16 anchor bolts embedded in the concrete would pull out if 17 the concrete or the allowable stresses would be exceeded at 18 that point, at some point below that, even if they were 19 immediately under itior.off to'one end of it, and I would 20 say, based on my experience, that I would question that 21 particular embed gapability:of-taking that load, yes.-

22 Q Do'you know whether or not the safe shutdown 4 A u

r 76 mgc8-6 1 earthquake for' Byron could generate that load at that 2 point?

3 A No, I've not done enough research to determine d that.

5 Q Let's refer to Attachment 3. Before we do that, 6 I have another question I want to ask you about your 7 Answer 17.

8 Do you know -- again referring you to the 9 strut and embed plate that you observed in the field --

10 do you know what the type or the size of the studs were on 11 the back of the plate for that particular location?

12 A In relation to the section that we discussed g3 13 _ earlier, 30 -- under the embed loading plat design section,

( )

'"' 14 which I can't seem to find at the moment --

[

15 0 34.2.

l j 16 A Yes, I believe that's it.

17 It appeared to me that in the structural analysis, 18 there is only one size. bolting used for a specific width 19 plate. They used three-quarter-inch plate of nine inch 20 width. They put studs on it in a particular pattern at 21 a particular spacing. There was no variance in that, 22 according to the criteria. There is a six-inch plate that l

e

)

y --

/^)

Ad mgc8-7 I wasahalfinchthrick,andthestudpatternonitwas 2 varied, but what was on the nine-inch piste,' it was 3

staggered from one(side ~to the other. There was a specific

  1. size stud used on-that plate,-and according to.the criteria, 5

both type plates were designed for.the exact same loads, 6

10 and-12 kips, I believe.

I

-Q So.'you are assuming that the studs around the-8 plate --

A Were exactl'y as the criteria require them to be IO for the width of that plate, yes.

lI And that's based on your reading of the Q

12 Criterion, Section 34.2?

13 Not seeing a calculation, just seeing the A Yes.

Id criteria.

IS All right. Now let's try Attachment 3.

0 16 Now did you write this document, at least the 37 first page of Attachment 3?

18 A I prepared it, yes, sir.

" Q .All right. And the balance of the page that is 20 3, where did they come from?

Attachment 21 y believe they were prepared by me or typed from 3

22 a document and prepared by me.

G gr. .

g _q-78 ,

,u,

-i I

'# mgc8-8 Q Are you sure?

2 A Oh,-wait a minute. No. .It' app' ears to be-a --

3 oh, it's copies of a document,'DC-ST-03-BY/BR. Those are d

the. specific sections that are referenced ~in the document.

5 on Att achment '3 ' that I've noted. It shows exactly -how 6

they're stated', listed and so forth.

'7 Q Now looking at the first sheet of Attachment 3, a

you've got various section. numbers' listed in the next to the 9

lefthand margin, and then thera are statements' appearing 10 after each section number.

' What is the significance of these statements?

12 Perhaps I'll let you take them one at a time for you to I3 answer them adequately.

Id A Well, .the significance'to me -- in some cases IS I spelled it'out, like, "Section 37.2. No definitive 16 statement that torsional stresses should be checked."

17 If you,look at.Section 37.2,;it says these

'8 eccentricities can cause torsional shear and warping I'

eccentricities. .Now it lets you-know that they are 20 concerned about this, because they state it, and the 21 problem with it is, there's no definitive statement as to 22 how you should approach this torsional shear and warping u

,e

II ,

79 mgc8-9 1 stresses or whether or not you should check for it. It just 2 says these can cause problems.

3 Q Do you think this statement should contain that 4 statement?

5 A This one or subsections of this, which the later 6 Sections, if you look at 37.2.1.g.2.C, 37.2.1.g.3.C, all 7 the C's seem to be torsional analysis not required, so they 8 did address it. They said you don't have to address it, 9 basically is what the bottomline came to -- the total 10 section.

11 Q So did that cause you.r,ome concern, then?

12 A Yes, it did.

,3 13 Q What is your concern?

( i 14 A That they were neglected.

15 Q They should have been considered; is that right?

"lo A' They.should have been considered as to the level 17 of critica1 ness,as to the allowable stresses that they 18 could have affected.

10 Q LookAng at the second item on the first page 20 of Attachment 3, you indicato a statement that says, 2f " Deflection and rotation of primary structural steel 22 ignoredsin deflection check," and then there's in

a. . .  ;,

. 6 L,)

s 80

'(M s ) mgc8-10 1 parentheses a question mark, and'then the words, " Members 2 . with pinned ends."

3 What does that mean? What did you intend by 4 .this question mark?

5 A It's a question mark. It's a' question to myself.

6 This was-made up to. flag things to me. Everything on here, 7 was a question. If you want'to know the truth of the 8 matter, in most. respects one way or the other, in this 9 particular case, I already knew what it was, because I just-10 wanted to have it there for future reference. But in any.

11 case, the question, " Members with pinned ends," indicates 12 that I questioned whether the absolute ignoring of 13 deflection was valid for members with pinned end connections, i O 14 primarily structural steel. That's what the section is 15 addressing.fPinned end'. connections cannot take any 16 deflection and rotation in the torsional aspect of the 17 word, and the absolute: omission of any deflection check, is omitted to check whether the member could even take that 19 kind of loading, and the end connections would have been 20 the place to check. I have seen pin-connected members that 21 have to be modified to fully-welded moment connections 22 because the torsional loadings were so great. The thing g.

s-O

l 81

> mgc8-ll I failed with pin connections.

2

,Q Did you determine this to be a problem at Byron?

3 A- It's in the criteria. It indicates a problem could exist at Byron. But no, I haven't been able to visit 5'-

the plant often enough.or,enough magnitude to review enough 6

supports and end-connected' members to determine whether or not they exist and it is a problem.

8 Q Have you' concluded that the fact that the 9

deflection check is ignored, as you characterize it, in 10 Section 37.2.1.f, does that constitue a design inadequacy,

' in your opinion?. ,

12 A It does, if they had at'tachments to pin-connected l3 em beams. They_could cause.rotatioh:of that beam.

\. ) j4 0 Well, is or isn't it a. design inadequacy. Can't 15 you tell from looking at the design document?

16 MR. CASSEL: Objection. Asked and answered.

II He just answered the identical question.

18 MR. GALLO: No. He said "if,' and that's not 19 giving me an answer to the question. In any event, I was 20 not satisfied.

21 THE WITNESS: If there are no rotational forces 22 applied to pin-connected beams, then, no, there is no problem.

5 BY MR. GALLO:

6 0 All right. Well, let's identify what kind of 7 problem we're. talking about. Are we talking about a design 8 problem or a hardware. problem at this point?

9 A It would be both. It would be a design problem, 10 because it is' oversight o,f; design. It would be a hardware 11 problem, , because it would affect the hardware. '

12 Q Sofif I.?look at parag'raph' ,(f) on the third page 13 of Attachment 3, based on what'you'just testified, I can lg g L\_)' Id conclude that,you'believe this statement in paragraph (f) 15 constitutes a design deficiency, because it says that-the l' 16 deflection and rotation of primary struct ral steel framing 17 may be ignored?

f 18 A That's right. I believe. I was sort of-

5 and it~says, " Safety-related Hangers." That's the main.

6 category that (f) is attached to.

18 MR. CASSEL: Design sufficiency?

9 " Torsion' included here. Question logic." That's the only 10 one I know of that'I' remember-does include torsion, and I 11 ' put down a comme'nt, " Question logic." 'I simply am 12 - questioning why they put it in one section. They omitted 13 it in infinitely more sections, when in reality, it is Id my experience in design that if'I tried to memorize this 15 document and design something, I would remember all the-

.16 times torsion is to be ignored. -I would never-remember that 37 one section where it's supposed to be' included.

18 But you consider that section to.be adequate, then?

Q-19 That's why you pointed this out for me?

20 Yes, that says it:should be included. I consider A:

21 that adequate.

~2 'A ~Let's see._ '37.2.l'.g.5. Based on_that one line,

.3 I-don't find that a deficiency, but-the subsections of-it make that one(line a very questionable item still.

~

4 5 36.2.'l.g.5'says,." Exact analysis must be 6 ~ perNormed for loads ~ greater than 20 kips." I questioned what it,would'do-for loads less tha'n 20 kips,-but then

~

7 8 the ABC' breakdown at the end of 3'7.2.1.g.5, if you limit 9 'it to the first three under t! hat se ation,_it says, " Assume

~

1 0 all masses lumped at shear center. Axial self-weight may

11. be ignored._ Torsional analysis not required." So it-12 appears to me that they liked 20-kips, to include torsion, x 13 you don't include self-weight, you don't include.the V 14 eccentricities of joints, but above-20 you do.

)

15 Now if that indeed is what was done, I have no 16 -question about above 20. kips, but I have a question for 17 everything below 20 kips.

is You see what'I'm saying?

19 Q Do you believe, then, that the Section 37.2.1.g.5 4

20 is deficient because it doesn't address what should be 21 done below 20 kips?

8. Can you tell me just what that item is?

.the first item.--

9 A' .W ell,.in. reviewing the documents, I had a 10 procedure I went through. I read everything.several times.

II In this case, this particular letter was an NRC letter-to 12 Commonwealth Edison, and on page 9, there's an Item No. 3, 13 and-under that item they'are discussing cable splicing.

' Id

'And in:this particular document they're discussing end-line i 15 splices.

146

And the question here, to me, came from another 17

' document concerning a butt connector review program that 18 I was familiar with. In reviewing the documents in the '

39 butt. connector. program, they were supposed to review 100 20 percent of the butt connectors.

8 connectors'versus a soldered type connection or I-joint.

In butt l connectors, the whole write-up that I had seen was 10 about the' crimp connectors, whether or not it had been 31 crimped by the right ' tool or whether or not there was 12 enough pressure on it and stuff.

13 Well, I have enough background with electrical

_O- id

~

stuff to know that end-line splices are equally made 15

, with crimp connectors, and the thing that seemed to appear 16 here to me is, the end-line splices were being omitted 37 because they were not butt connectors, and to me, end-line 38 splices or crimp connectors are as critical in this 19 butt review program as the. butt review program stuff they 20 reviewed.

21 They omitted -- the program-should have been a 22 crimp connector faulty installation review program, which J

splices or anything.

7 Q- Now you say the'end-line splices were omitted, a Who are you and you_ refer to "they" omitted them.

10 A' I said it appears they were omitted.

12 A .W ell, they were omitted by CECO or whoever 13~ was to do this 100 percent review of butt connectors.

fs i

id The whole problem was not butt connectors; it was crimp 15 connectors, and the program should have been 100 percent 16 review of crimp connectors, not butt connectors. And had 17 that been-the case, there would have been some end-lin'e 18 crimp connectors in the program.

i 19 None of the documentation I read -- and I mean 20 none of it -- came flat out and said end-line splices 21 were included because they're crimp' connectors.

about. Okay.

( /

Id A I've seen lots of letters on reviewing butt 15 connectors or butt splices. I've seen a few, I think, NRC 16 inspection comments about faulty end-line splices at I7 penetrations. End-line splices don't necessarily exist

'8 at all penetrations. They exist end line, wherever they 19 want to splice a cable. For that reason, the addressments 20 or letters I've seen only address certain connectors in that 21 ~

end-line splice category. At tenetrations, they did not 22 address the end-line splices totally as to crimp problems.

10 problem with end-line splicing, or did it just trigger a 11-memory response in your head that caused ~you to.say, "Aha, 12 here's a potential problem," as you've explained it here.

13 A Well, it addressed a problem with that particular O 14 type of one, NRC-363 with an end-line splice at the 15 penetration. That one is addressed by that letter. Now --

16 Q Does-the letter raise the --

17 MR.'CASSEL: Let.him answer the question.

18 THE WITNESS: It did raise.-- it didn't raise 19 something I'm familiar.-with._. It raises something that 20 everyone here should be hamiliar with'.

21 After-reading the butt connector letter-22 documentation, the whole butt letter or butt splice issue

-23 is not butt splices; it's crimp connectors. All you have A

v

102

- I to-do is read all that' documentation, then read through 2 all the other stuff, and you see that end-line splices 3 are -- they come in very sporadically with being deficiencies 4 at penetrations, but you don't see any documentation as 5 to end-line splice connectors.

6 BY MR. GALLO:

7 Q Did this letter address that point?

8 A I-don't believe it addressed the totality, 9 except at penetrations. I think it was specific 10 penetrations, but I can't give you a more definitive 11 statement. I'd have to' pull the letter out and reread it 12 again.

~9 .because it failed the test the second time.

10 Q Mr. Stokes, aren't these first four items where 11 you refer to NRC letters merely matters that have'been 12 identified by the NRC Staff'through Region III,andLremedied 13 by Commonwealth Edison in response to the NRC Staff?

O 14 A. . The Staff.has raised these questions to some 15 extent. -Whether or not the solution has been completely 1-6 documented and is acceptable.is another question that I 17 can't answer,,because I haven't, as you say, seen everything.

18 I'm only one person. I haven't had the time to read 19 absolutely everything. I don't have a -- I don't have a 20 limitless brain. But in any. case,-that question is still 21 a question to me from other documents.. That document.

22 doesn't state specifically that that one was corrected.

.i A It's a Sargent & Lundy document. That's the

[2' drawing number of it.

3 ~Q Now this'is a potential-concern. What is the

~

4 nature of.the concern?

~

5 .A There is a load table on this.- It's very

< 6 briefly described. There's a load table on -- these 7 documents are concerning steel conduit installation and a design.

9 Anyway, there is a load table'.for steel conduit 10 op .this document. It's specifically called out, load table,.

ii steel conduit.

12 I compared that load table with the load table 13 for steel conduit in the unistrut catalogue, which I had, D

\- .i4 which statement at the bottom st'ated it was in compliance 15 wish the '71 version of the National Electrical Code. The 16 numbersffor the weights in that table in the unistrut 17 catalogue;were larger than-th " numbers in the table of is Sargent & Lundy's drawing. The -- this may be. answered, and i9 I'll go a' head and throw this in.

20 In the Sargent & Lundy docum,entation, they 21 stated they used an '83 National Electrical Code. If in the 22 '83 version,'which I haven't had time to look, the loads are S

'?

r I[ .i what is'in this table,-'and all the components listed in this

-2 . table or the weights for those components were purchased I

! '- 3 . irt compliance with the ' 83 Electrical Code, .-I wouldn ' t U

4 have any question with'this if those things happened.

5 But the problem with this, as far as I see.it, 6 is unless the '83 version lists the same load table values,

! 7 -Sargent & Lundy's values appear to be below what the National 8 Electrical Code requires. Now --

9 Q llave you made this comparison?

ni A Yeah, I compared.the tables.

ii O So you compared the tabic in the unistrut

! 12 catalogue with the table shown on this drawing?

33 A Yes.

I /\

~

Q And you concluded that the load' table on the i4

~ ~

15 drawing is inadequate because it doesn't coincide with the

~

16 unistrut catalogue table?' '

l 37 A I didn't decide that it was inadequate. I said la if the table was per'the '83 code, and the '83 code is-p, identical to the table, then I only have one other question.

20 That would be whether or not the components put in the plant l -21 were por the '83 code instead of the '71, when purchased.

And']:he thing that keyed my mind

3 And then later when I was reading the documentation d'

on cable pulling, this same article.and memory came back, 5 and_I pulled it out to make sure that it was stating what I 6 remembered.

7 This article is not a problem itself because it a addresses factors that should have been addressed in pulling 9 The equations determining safe pulling loads and so cable.

4 When I raised this with Sargent s Lund, I believe

~

5 cm a Wednesday some number of . weeks ago, I was told in that 6- meeting NDE exams were'never in question in the reverification 7 and were omitted.

8 In reviewing all the documentation _on PTL,-

9 includingthe'reinspectionbehort, I find that PTL was so responsible for all NDE exams, but,they had the worst 11 failure-or' worst inspector qualification record --

12 0 Mr. Stokes, you-are rambling now.

13 A Well, I'm sorry.

- 14 Q The question that I asked you was what was the 15 nature of the potential concern that you had in the second i6 item, and I repeat, it says minimum pipe wall thickness 17 not met. Repair performed.

18 Now what is the concern or potential concern that 19 statement represents?

20 A It has two:

21 One, the repair performed, if it was part of the.

l 22 reinspection program, would have been significant from

7 .A' Beyond that,,=it zexpands the question of whether 8 NDE as atwhole'should have_.been questioned as an attribute 9 when'I-was told it was'omitted.-

~

10 O' All right. If I understood your testimony just.

11 now, you arejsuggesting that thetfact that this minimum 12 pipe wall thickness was repaired contradicts the Sargent &

E 13 Lundy testimony that none of the reinspection program O 14 discrepancies had design significance; is that correct?

15 A Well, it does to me if, as I said, that repair 16 was performed due to an inspection during the reinspection 17 . program.

18 Q What discrepancy are we talking about here?

19 A I'd have to thumb back through severa1' documents.

20 There's several where they repaired stuff. They're NDE 21 re ports , I didn't write the numbers down. If you'd like

11 Q My question is, is it your testimony-that since 12 they were' prepared -- repaired, rather, that meant that

16 A If they didn't have design. significance, ..

I-17 wouldn't have repaired it. There is a definite question is there.

19 Q So you think there is a correlation between 20 design significance and repair?

21 A Well, I've got a question about.why they were 22 repairing it, if it's not design-significant or safety-

'l~h t/ 1 What is this' item on computer printouts by 2 inspector for Hunter-Corporation?

3' A Oh,' boy. There's.a bunch of' computer printouts 4 that I. reviewed and I have copies of, even though I didn't really want them mysel{. .But;they are listed by inspector.

5 .

6 .The inspector numbers here are' listed. The document ID 7

number is what is shown onjthe-documents._ Those things 8 appear to be the ' work ~that the inspector did on a 9 computerized basis. It listed what was reinspected,.what to was inaccessible, what was not accessible. There was 11 quite a few things.on it.

12 The thing that -- I initially didn't even care 13 to look at them, and I finally reviewed them primarily for

(' -

14 what was inaccessible, and that is why that's listed here.

15 For instance, the first inspector says 16 inaccessible due to a lot of retrofit on feedwater system.

'only included two feedwater system problems.

This' documentation all' owed-me to compare the

-5 l actual problem with what's on this list of feedwater stuff-

-6 that this guy'.wasIlisting'as inaccessible. The two that 7

were reviewed in the-49 or so that were reviewed did not 8

include any of this feedwater stuff that was inaccessible 9

here due'to retrofit.

37 The third one --

'8 Q I'm sorry, I was just going to --

4 Cleanl'ine ss . The word " cleanliness" -implies 5 that it's filthy,.-you;can't visually see it or inspect it.

6 There.is a category'that was omitted from.the inspection 7 -called housekeeping, and I assume housekeeping is an ongoing 8 practice of keeping things clean. But to make something 9 inaccessible because it's so filthy, when_you could go-

-10 out and clean it, if that's indeed the way this was written, 11 says why did they not look at this? It's not reasonable 12 -for them to say it's filthy, we won't look at it.

10 mean.there's hot functional going on the other day when we 11 toured the plant. It was warm, but not impossible to 12 perform an inspection, I don't believe, just because of this 13 statement,' hot functional, without a much more definitive 14 statement,that casts that question, yes.

IS Q All right. Now turning to the item that starts 16 out Table 38.2-1, what document'is that table from?

17 A I believe it is from'the first document which is we were discussing, the main Sargent & Lundy criteria.

19 Structural project design criteria, Byron-Braidwood. It's 20 the only document, to my memory,.that-went up to 38. It 21 actually, I think, went a little bit beyond 38.

/~h i) 't - start out -- well, indeed, if.you look at the rest of the' 2 page,.each line seems to start out "omitted."

3 A. Yes.

4 0 'What does that mean?

5 'A- Just that.

6 Q Omitted from what?

7 A All procedurals that I reviewed, everything that-8 was given to me, supplied to me, there was absolutely no 9 section, no drawing, no nothing concerning through-bolt to ' design criteria. There was no-flare bevel or bevel weld 11 radius tube steel specified.

12 In other words, there was no table as to what the 13 . radius would be for the design team to use for various tube 14 sizes. There was omitted no as-building, 10 percent over-15 stress factor, and I limit that.

I 16 Now there was one document that covered that. It l

l 17 was -- this one line was not in the main' criteria. It was 18 not in the DC-ST-03-BY/BR document. There was a proprietary 19 document that I was allowed to review that included 20 several comments on both 10 percent overstress, zero percent 21 overstress, 33 percent overstress, and actual -- just --

22 you.could fail;one' member every so often of a certain type comment. But'at the moment I can't give you that document's number.

12 0 Go ahead, what is Attachment 77 13 A Well, that's probably.one I included for another b

(_- i4 point, and I was just fixing to -- yes. I'm not sure just is what that is. It's like I said -- or if I didn't say it, 16 I'll say it now, it's marked safety-related, it's got no 37 calc number, no revision. It's not reviewed, not approved, is it has no client, no project, project number. This thing is pp -- was almost, as far as I can tell, untraceable. But it 20 had -- and this copy is as terrible as my copy had. In 21 comparing several sheets of this thing, I was able to 22 determine this number at the top, the 117.57. It's something

?,

1 4

O

12-5 124 I

STD 117.57. I couldn' t even determine who prepared it. If 2 you can read that, boy, I could use you.

3 I could determine on secondary pages what --

4 who did it. It's got Shenean as the preparer. Still not 5 reviewed and not approved, but here he finally did stick in 6 something that helped me a little. It wa- CECO, Byron-7 Braidwood, and some numbers.

8 I still have not really found out anything about 9 this document. It's concerning weld reviews. It's obvious 10 from the write-up -- undercut -- boy, that looks like 11 reinspection stuff. You've got the 10 percent reduction, 12 you've got undercut and different sketches, and what really 13 caught my attention when I got through this document was it s

(' I 14 gets over and it didn't even have a page number. It has a 15 nice picture of tubing intersecting plate, and it calls out to the weld symbol for the tube-to-plate weld, R(E) with a bevel 17 weld.

18 What really caught my attention, after talking 19 to Sargent & Lundy that Wednesday several weeks ago was the 20 next page con'cerning' flare bevel groove welds, and it appears 21 that whoever prepared this did some research, and it states 22 typical field measurements indicate.the actual radius is between T and 2.5 T, where T is the tube wall thickness.

f

\_)

l 4

'125 12-6 Therefore the design assumption of R equals 2 T, an 2

offective throat equal to 5/16ths R per AWS D-1.1 is not-3 applicable.

4 Now, that states everything in a nutshell as 5

far as I am concerned. I, on Wednesday discussed an 0

allegation which I raised at Diablo, and I had absolutely 7

no proof that it would go anywhere where, and all of a sudden a

I was reading through this documentation and dumped in my lap was a flat-out statement by somebody at Sargent & Lundy 10 stating that their design assumption of R equal 2 T is not applicable to this work, and that there is T-radius steel in 12 the plant.

I3 g) They make that statement, but they don't sign it.

NJ 14 I guess it was Shenean.

15 But, in any case, this thing in fact did all the 16 research that I needed, that I wanted to do in the field. I wanted to measure stuff when I got my field trip, if I ever 18 got one that I could go on when I wasn't too busy.

This document did all my review work. It says 20 flat-out everything that's been assumed by Sargent & Lundy, 21 if it was based on their design assumption of R equal 2 T is 22 not applicable to Byron. Now --

126-12 ,.

._/# -

(_,l ' -i O. Okay, are you finished?-

~

2 A Yeah, I think that's plenty.

3 0 So I guess based on your testimony, this whole a question of flare bevel weld was not'omitted from the 5 documentation you looked at?

6 A It was not -- I said it was omitted from 7 procedures, criteria.

g Q And this doesn't qualify as any of that, Attachment 9 7 I'm referring to?

30 A No, it doesn't, because I don't know if this ii thing has been' destroyed by -- well, I know it wasn't 12 destroyed, because they gave me a copy of it somehow. But i3 what it' does tell me, because it's not reviewed and not ja approved, that somebody' undoubtedly didn't ever want to use 15 this thing.

16 But, then, on the other hand, the stuff that j7 follows the flare bevel stuff on thin plate sheet welding, 18 D-1.381, and the' transverse loading on the weld calce, it

.iq appeared in the calculations I saw,'they used these numbers 20 as the'capa'ities c for the wolds'wNich says they should have.

2 A There was an inspection report.

3 ~Q If I turn to page F-13, really your second-4 sheet of Attachment 6, and I look-under the item that 'you 5- have " starred, 'there is- a reference to a drawing detail 6 _ called DV-164. And if I look in the finding, there is a 7 reference to DV-162.

8 A Uh-huh.

9 Q Do you understand this to mean that what is at to issue here is the drawing detail DV-162?

11 A No, the allegation reads in quotes:

12 " General surveillance of this project 13 illustrates that approximately 90 percent of the B welds O 14 on that drawing are 1/8th undersize where tube steel has is been used. In most cases this represents a 40 percent to decrease in size and 55 percent in strength."

17 It was obvious to me by reading that ---maybe .

18 incorrectly -- that they were discussing flare bevel welds 19 on tubing which someone had made an allegation against the 20 flare bevels being undersized 1/8th of an inch, which is 21 quite similar to the allegation I raised at Diablo Canyon 22 - in the relation of quarter inch fillet welds and requested --

'3' O Do you know whether or not there's a drawing 4- detail called DV-1647

.5 LA No, I'm not even familiar with what.DV-164 or 162 y 6 or anything is. It wasn't in part ---it wasn't in the

.7 document. >

8 Q It's my understanding then that you just assumed 9 that the welding involving the tube steel in this allegation 10 was flare bevel type welding; is that correct?

11 A I did, yes. I may have incorrectly. That 12 would be-the same quote, almost identical.

13 0 Mr. Stokes, I'm going to show you a drawing O.

\/ 14 prepared by Sargent & Lundy which has on it drawing detail 15 DV-162. We have marked the area for you.

16 MR. CASSEL: Did you say this was 164 or 162?

t 2 BY MR. GALLO:

3 O And on this drawing is detail DV-162. I' wonder, 4 Mr.' Stokes,.if you can take the NRC description of the-B 5 weld that they are talking about and look at the drawing 6 ~ detail DV-162 and tell me whether or not the weld-shown 7 'as the B weld'is the. flare bevel weld or a fillet weld.

8 A The B weld here is a fillet, which wouldn't 9 apply to a flare bevel, no. So, thank you.

10 0 Did that change your reliance on this Attachment 6 11 for purposes of your answer?

12 A Well, it could be extracted from the documentation.

13 as far as I'm concerned. If I had presupposed that the O 14 allegation was tube steel, flare bevel welds was the issue is here, if that's the -- since you've shown me that it's not, 16 it's obvious that I'm raising the issue for myself, as per 17 the attachment after this, 7.

i is Q All right.

19 A I thought it had already been raised. I'm sorry.

L 20 It's something new.

21 Q Let's turn to your Answer 29. It's on page 20.

22 If I understand this answer, Mr. Stokes, you L

O a f k

y: -

I 132 I 13-5 1 have questions on calculations and assumptions found in 2 Calculation Book 19.1.2, and then your subsequent 3 questions and answers that appear deal with, by my count, 4 four of those items.

5 Let me make it easy for you. By my comparison, 6 you have not addressed Section 19, pages 1 through 5, and 7 Section 21, page 113 and my first question is -- maybe you 8 want a change to check that out to see whether my evaluation 9 is correct?

10 A I think I sort of looked through it the other 11 night, and I noticed that what you are saying is true. I 12 didn't --

,_ 13 0 Well, are there problems in Section 19, pages 14 1 through 5, and Section 21, page 113?

15 A I believe there are, yes. I think I checked out 16 all the numbers per a list that I had.

17 0 But they're not included in your testimony?

18 A In haste -- I'm sorry, I didn't include 19 absolutely everything that I found. I intend, and I had 20 planned on supplying a list to both Ceco and the NRC at 21 some point when I get it completely finalized. I'd like to 22 be abic to strike some of the things before I give it to

(~1 v

5 t ,

13-6 133--

1 l')

Ek/ I - them.- But this list, as I have said already,'or will state, 2 is not absolutely everything. In some. haste.there's been a 3 few things omitted. I stated that, I think, a little earlier

-d 'in relation to.the -- I don't think I included the document 5 on the telephone conversat' ion that'was not documented.

6 There was a'few others that now that I'm thinking 7 back along the calculational' side of things, I didn't 8 include in haste, but they weren't technical as much as 9 documentational issues that are QA-oriented. So. . .

30 Q Now, as I understand, the item-that you referred 11 to in your Answer 30, . is this a -- first of all, did this 12 involve a discrepancy that was detected during the course 13 of the Byron reinspection program?

O 14 MR. CASSEL: I'm sorry,~ Joe, you said Answer 30 15 we're now on?

16 MR. GALLO: Yes.

17 THE WITNESS: Was it detected during the Byron 18 reinspection program?

19 BY MR. GALLO:

20 0 Is this a discrepancy that was detected during 21 the Byron reinspection program?

15 0 Turning to your very last answer in your 16 testimony, this document you refer to, Drawing '6E-3393B, 17 is that a Sargent & Lundy drasing used for design purposes?

A_,L 1 whole' package, which was supplied to me, is 6E-3393A, it went almos* through the alphabet. It missed several letters 3 at the end and then came b'ack AA and BB, I believe, if my 4 memory serves me correct. It was quite a substantial 5 package of drawings on this particular --

6 O On page 26 of your testimony, you. refer to the 7 unistrut catalogue. Is it your understanding that Sargent 8 &.Lundy uses the design tables that are contained in the 9 unistrut catalogue for design purposes?

10 A It's not my understanding. It's sort of obvious 11 from the questions'I raised concerning KL/R that they may 12 have used unistrut, .8 for the K factor, which would make

-l 13 quite a substantial change in the table that I was looking 14 at, and the correctness of it for end connections..

15 And so whether or not they used it specifically, to I can't say, but it appeared that they may have relied very 17 heavily in the unistrut catalogue on the .8 factor, and 18 possibly the KL/R is listed for that factor, instead of 19 doing their own analysis of KL/R for the actual conditions l 20 in this table.

21 That was the explanation I reasoned out on my 22 own, but I can't go beyond that.-

In that trip, 3 the first-thing that I -- we was looking at electrical 4 stuff, and the first thing-they carried us to was all these s' tray' supports that were-extremely long off the ceiling, 6 and I remember.asking one of the CECO people -- I think it

0 14 cable trays are conduit--supports.

That's what we.were is looking at in the field, a lot of cable tray supports,

'16 GXtremely'long members off the ceiling. If-I said HVAC, 17 I'm sorry. The same-supports, by the documents I saw, is could have HVAC as well as cable trays on the same 1

'19 structure. And if I said just strictly HVAC, I'm sorry. 'I 20 There.would have been a combination of those two, maybe 21 just one or.the-other. -The ones we saw in the field that 22 I'm specifically referring to in that statement -- I believe a

3 0 Now I'm confused by your testimony. On-page 26, 4 you say that you reviewed many designs that exceeded the 5 .200 factor. And what I'm confused about is whether you 6 actually reviewed documents that exceeded this factor, or 7 it was based on your tour with the Judges that day and 8 you observed these: during; your tour.

BU7 9 A Some of both. 'The documents'that I start.out with, 10 the table indicates that the table-is incorrect. That

~

11 indicates that many' supports designed by that table would 12 be, in effect, incorrect.

13 On visiting the field, to continue, in

~O 14 extrapolating this, I visually saw many that exceeded-and 15 complied with this table. I actually saw them. .They were 16 shown to me, and they fit that table exactly.

17 On top of.that, in the calculations which I have 18 reviewed, which were towards the weld's end, which-only 19 was one very minor part of these things,-there was 20 reference by sketches of the configuration in the structure.

21 You can say I presupposed that many of those structures 22 are shown with the in excess of 200 KL/R, because in 22

5 I can say is, I reviewed those three things, and the same 6 problem is obvious in-all three,--'the field trip,.the

-7 document, add in thd cal $ulations.

8 0 =3 Let me see if I follow you. Based on your 9 review of the--. table:that is discussed on page 25 of your 10 . testimony, you conclude that'the table is inadequa'te,'and 11 then based on your field trip with the Judges, you actually 12 observed designs where the factor of 200 was exceeded.

13 Is that a fair statement?

f-

  1. 14 A In my opinion, I saw stuff. I didn't need a.

15 tapemeasure and a ladder to get up and do a real detailed 16 dimensional check. But just off of judgment, I would say 17 they exceed well over 200.

18 Q All right. Are you familiar with the testimony 19 -- of Ernest Branch?

20 A I have read Mr. Branch's testimony, yes.

3 Q Did you review any of those calculations during 4 your. review at Sargent & Lundy?

5 A- Many didn't have calculations. I've got the

11 In many cases, they were simply stated; " Accept-12 able," with no calc.at all.

13 0 We're talking about the 49 ASME welds?

(-#) 14 A Yes, yes. There was a-little pipe wall thinness l

15 calculation. I don't think that part was in the calc, 16 though, the pipe wall thinness. But they referred to the 17 thickness requirements and what was calculated as being 18 the requirement. I wasn't sure there was an actual-19 document where they sat down and said the thickness and 20 the pressure and all this stuff, and they came up with a 21 number. I didn't'see that, no.

22 Q It's Mr. Branch's testimony that 49 ASME walds,

I

'.-9

142 I which were detected with discrepancies during the 14-5

'2 reinspection program, were evaluated for their design 3 significance, and that none had design significance.

d And I am.asking if you, in your review at 5 Sargent & Lundy, looked at any of those evaluations?

6 A I looked at;those.three. documents, and they 7

were --

8 Were those-evaluations in'there, in those three Q

9 documents, to your' knowledge?

10 A I can't say it was completely there. There was 11 an evaluation in there, yes, as well as the entire listing 12 of all of the welds.

13 Do you know whether the evaluations that Mr. Branch

15 A I have no way of knowing what Mr. Branch reviewed.

16 He's never supplied me with a list of what he actually 17 If I made a statement on what he reviewed, looked at.

18 I would have to presuppose that -- make an assumption on 19 that basis, and I'm sorry, I can't do that.

there 8 The question before 37, the one you omitted, 9 discusses whether any Sargent & Lundy. calculations for.the 10 reinspection program had caused concern, and I list BRP-1, 11 okay?.

'~ 14 was only 1/64th of an inch.

15 The actual numbers shown in this cale indicate 16 that this thing fails, period. The only way they got it 17 over was they used the 1/64th accuracy to say, "Well, we is assume this gauge was out of tolerance, and we boost it 19 over." So that. caused concern. But that was related to 20 weld gauges used in inspecting.

13 Other than that -- and I'd say that makes up h, 14 half of the 49 or more.

15 Q Now what was the nature of-the ASME weld 16 evaluations performed by Sargent & Lundy? What did they do?

17 A Well, from what I could determine from this 18 document, the nature of the problems primarily were 19 insufficient weld thickness.' It appeared they had done a 20 calculation to determine minimum pipe wall thickness. . That 21 was not part of.the package, and I assumed maybe-the guy 22 just did it on a rough sheet of paper.

'9 Q Now Mr. Branch also testified with respect to 10 his evaluation of certain discrepancies involving what are 11 called in the reinspection program objective attributes of 12 Hunter. Did you review any of those evaluations?

2 McLaughlin?

3 A Again, I don't h' ave a list of what Mr. McLaughlin 4 included in his 356 to' compare it to the documentation I 5 have. But just going on what was supplied to me and:what I

, 6 have seen, I would assume that I've at least looked at part 7 of the 356 Mr.~ McLaughlin testified to, yes.

8 Q Again, do you recall any disagreement with those 9 evaluations that you --

10 A I'm sure there's got to be a few in there. I 11 had disagr'e ements with quite a few .cif .his calculations, but I 12 didn't'h' ave e'nough time to include absolutely every calc r

13 that I looked at, that I had a question on.

14 The other thing is I didn't have time to go back 15 and redo a lot of the cales that I had done preliminary stuff to on and had a question over to verify that I was correct.

17 And so I omitted stuff like that. I'm sorry, I --

18 Q You don' t have to apologize. That's not needed.

19 So you're telling me you noted disagreement with 20 certain of the Sargent & Lundy evaluations of the 356 21 llatfield AWS welds, but you didn't note those in your 22 testimony that you filed in this case; is that correct?

5 in response to a question from Mr. Wright. You say you 6 reworked the aspects of a number of engineering calculations.

8 A Well, no, I said in my review I reworked aspects 9 of a number--when I reviewed some of these calculations I 10 was just talking about, I performed rough cales on sticky

I \

\ ,) 14 Q What does the term " rework' mean here?

15 A I used it like rework as far as reinspection, 1-6 re-evaluate, requalify. It's Sargent & Lundy's work, it's 17 the work they did, as far as qualifying the safety 18 significance, design significance of the joint.

19 Q Did you run an independent calculation yourself 20 when you did this, or do Stokes calculations exist? That's 21 my question.

10 BY MR. LEWIS:

11 Q Mr. Stokes, I'd like you to look at Attachment 2-F 12 to your-testimony. 2-F is simply a one-page excerpt from

,, 13 the Sargent & Lundy design document that we've been talking l l

\# 14 about.

15 Have you located it?

16 A Oh, yes. Okay.

17 Q I'd like to direct your attention to the last is sentence on that page which reads, "A separate embedded 19 plate design shall be made where applied loads exceed the 20 capacity of the grid plate."

21 A Yes, I see that. I read that earlier.

22 Q You testified earlier that you were concerned

'2 I belie've you were talking about struts or~other members.

3 'A kes. ,

4 Q,' iben you read this sentence at the bottom of 5 2-F, did that indicate to you that the type of analysis 6 that you felt should be done would, in fact, be done where 7 applied loads exceed the capacity of the grid plate?

8 A - If the person was aware of that one line, 9 my experie'nce in this' whole little narrative here on embed to plates, that plates typically are designed for use without 11' knowledge of what's going to go there in many cases. The i

12 fac5 that the thing was on the plate indicated two things

,_ 13 from visual. There was a fairly large weld to the embed

( )

14 plate which had, you could tell, heated the concrete on 15 the edge. The attachment was as wide as the. plate almost, 16 which the plate had to be a six-inch plate. There was a 17 problem with overheating of that half-inch plate, because is it appeared they had put on quits substantial fillet 19 weld, and then on top of that, you tad a very sizeable 20 attachment for the width of the plate, and whether or not 21 this calculation indicates that it should be redone before 22 you attach it, and the' guy who did that analysis or did that a

4 But -- is that clear?

~

5- Q Well, to some extent. Let me ask you this. In

~

6 other words, if I correctly understand you, you are 7' ' concerned that maybe the person who would do this 8 calculation perhaps would not be aware of this provision?

9 Is that part of what you.--

10 A. Yes. And the calc's book size'is almost of,the il book,.in the early part of the book, there was a series of

+

12 written documents such as what is attached here to my 13 testimony, explaining assumptions, what's relevant, what's s

34 not relevant, such as the undercut discussion. It's 15 obvious to me that in this review it was likely they hired to people such as myself without any prior Sargent'& Lundy 17 experience to do with the work, because I heard there had 18 been a layoff some fews months ago before the review was .

19 required, and the people may not have had this document, i

20 the criteria document. In other words, it may have. existed, 23 but it was something they weren't exposed to due to'the.

22 rush of doing these recalculations.

16 Q What was the basis for your assertion that 17 piping supports are affected by fatigue leading?

18 A They are affected by dynamic loading. -Water 39 hammer is the dynamic loading. Seisdic loading is 20 dynamic. I've been in some operating plants, you know, 21 that the pipe -- fluid runs through it and it vibrates 22 from one side of the support to~the other, rattling quite

6 A Part'of'it.

Cycling time. It would be over.40

'7 years significant. 'You'd have to' sit there and count how 4

8 many times'a.second'it changes and-then multiply it over-9~ a.few years. But water hammer is part of that,'.too. You

,10 have to take into account how many times a year. You can a

11 estimate' valve closures are going to occur.and these other 12 issues that will cause the extreme magnitude of loading 13 that water hammer causes.

.I .

I4 For instance, when I was at-Southern Services, 15 in my earlier discussion of what I was doing, I said I 16 worked on the makeup water lines offsite from Miller steam 17 plant. In doing those thrust blocks that I alluded.to, 18 I.had to consult with the ASME department expert on water 19 hammer. He told me that I had to design for the lines 20 for approximately ten times what the design load was to 21 account for water hammer loads, they were that much larger.

m/ 1 the' analysis to get supports that would take the loads 2 for these 24-inch lines -- when I found I had an extreme 3- problem with designing something for that magnitude of 4- load, I' looked at the. piping analysis layout drawings, 5 and I found out that there was potential for a surge tank.

6 Now one of the courses that no one' asked me about 7 here is pipe flow theory and fluid flow theory. I took 8 courses in that, too, by the way. And I'm aware that 9 another alternative between designing for loads is to put 10 a suppression tank on it or a surge tank or a few other 11 little goodies that can take out that load.

12 Well, it just so seems that they have this tank 13 potential, but they didn't want to use it. They were

/,s) 14 keeping it as an ace in the hole, and I negotiated to have 15 the loads reduced, based on that surge tank and have 16 it installed, rather than have them design thrust loads l'7 and then have them put the tank in'later.

18 So from that respect, I'm quite familiar with 19 piping thrust loads, water hammer, and jet impingment and End 17 20 a lot of other stuff.

21 Q Mr. Stokes, do you'know what position the NRC 22 has taken? There is a reference in the annual report that I'T ts' l
