2 for the purpose of clarifyinn some technica]

1 ,

activities.at Comanche Peak rower Plant. It is a follow-un 1

of an carlicr interview that we did on August 2, 1984; how-5 ever it does cover some different subjects than the August 6 interview. Thelocationoktheinterviewisat 9 I'm not in Fort Forth, I'q 10 ,

MR. FESS?'AN: Present at the interview

! ji 4

12 are myself, Dick Wessman, for the NRC Staff; Paul Chen, NCR 13 Staff; and As we've agreed, the interview isi j4 being transcribed. [

15 The NRC has some questions in the areas of some 16 welding activities out there and also some questions con- .'

i  !

[  ;- cerning work on the main steam pipe that occurred out there y gg a couple of years ago. [

19 Paul, if you would, let's pursue the other

! 20 questions and then we'll come bach to the main steam line questions.

i* -

MR. CHEN: I have some questions here related to some 22 things that were mentioned in your 23 puif -

vou mentioned. a tran that l 3 you tried to firc three tincs. You said that he was a a general foreman on the night shift, and you implied that he ,

, 5 was incompetent. Can you. identify this man for us? ,

. r .

6l _

1o , I can't. It's been many, many f 4

l moons. l

. ,- m i 8 MR. WESSMAN: let me show you that_ )

, 9 again, if I could, and see whether as you read the te'xt of 10 that whether anything comes to mind that might give us a 33 little additional information on that. We're in the middle '

12 of page 6 of that document, I believe, and read, if you 13 would, for a moment.

14 All right. I know what I'm talking 15 about now. I can't think of his name. His name is in one 16 f my affidavits. Hollis.

i j ;7 MR. WESSMAN: H-o-1-1-i-s?

g gg Yeah, I think that's it: Pollis.

39 MR. CHEN

Is that his last name?

Yeah, that's his last name. This is 20 N

!. ,I a man that I tried to fire numerous times.  !!e done several i

things that were not up to standards. I!e done several things--the man was a scaffold builder. He built scaffold.

23

He was a very--pardon my French, ma'am--piss poor framo i i

carpenter. I tried to fire this man on numerous occasions j

4 anythina to specs. Hollis Bogart.

5 MR. tvTS S.'1AM : I!is first name was 1:ollis?

i 6 -

Hollis Pogart: Hollis Pogart was hisi j name.

I g MR. WESSMAN: Do you recall an approximate timeframe ,

9 that this fellow was working there?  :

10 It was about--I imagine about a year before I got fired; that was on jItwas  !

33 12 about a year before that. This man wasn't qualified for i 13 nothing. He built some stuff for a Gold Hat, built a i

j ,; porch and so on, sun porch, and that's the only reason he j had a job there.

l a_

i-MR. IfESSMAN: Was this gentleman a Gold Hat? l No, he was--well, he later wound un

. as a ceneral foreman, which was next to a Gold !!at; but I've j IS forgotten more than that man ever remembered. l 39 j MR. WESSMAN: Anyway, his name was Hollis Bogart, to 3 your recollection. '

{

i ~

/  %

22 M i Right. l MR. WESSMAM: Okay. With that we ought to be able to i pursue it via records at the plant. Go ahead.

MR. CHEN: The second question relates to something  ;

,, a_

I

t 5

I i that was mentioned in your sworn statement of June 'R3 in 2 ,

which you talked about torch cuttina bolt holes in the bacl.

3 i side of tube stocl that would be used for anchor holts.

l 4 i _

,Right.

5 liR. CHEN: Was this a very common practice?

6 Very common, especially with people that s_, -

7 didn't know what they were dealing with.

8 RR. CHEN: Can you elaborate on that for us?

9 Well, I tried to explain .to you-all l, t -

i 10 before that you have got a wall which a bolt is supposed to!

. 11 come out 90 degrees. These bolts are set in a pattern when !

12 they're poured in the concrete. They are not 90 degrees.

13 There's no way. This Hollis Bogart was one of the charac-14 ters that poured this concrete. It's easy to set up a 15 form and say, "Here it is." tihen you go tying in precision 16 steel where you're allowed an eighth and'a sixteenth and

! 17 a minimum, it don' t work that way. This bolt comes out of i 18 the wall--we'll exaggerate just a minor fraction--at 45

19 degrees. If this bolt comes out at 45 degrees, you heat i

! 20 this bolt and turn it 90 degrees in order to fit a piece of 21 six by six tube steel. When the inspector looks at it, he !

i f.

looks at it as it's coming straight through. All right.

.22 23 I!allis Bogart, which turned in to be a general forenan, 24 cut holes four and five inches in diameter in a six-inch 25 piece of tube steel in order to get the bac!: part to go ,

~.

4 i I was told, " Bob, don't look at it." <

5 j Mn. CllEN: Given 100 supports, how many of those 100 6! would you say would have this problem?

7 ' Fifty percent.

6 MR. CHEN: I just wanted to get a feel for it.

9 M Well, the concrete inserte were not 10 put in 'the way they should have been. 11 hen you put a con-11 crete insert in the wall--I don't know whether you ever 12 poured any concrete or not--the concrete moves things uo, 13 down, sideways; and when you put in a tube steel that has 14 to be flat up aga' inst the wall like so--okay?--if it's not 15 flat, if it's cocked any way incide that wall--this, that, 16 up, down--then you have got a piece of steel coming out here 2

l 17 that's not 90 degrees; it's up, it's down, it's sideways, j 18 one side or the other. This is what !!ollis Bogart caught, ;

1

the back side of the steel which CC don' t see, nobody can l 19 i

(  ! 20 see because you have--in most cases you have a six by six I  !

21 one-inch plate with an inch-and-a quarter hole in it. It l ,

22 goes against the wall, the tube steel goes up against it, 1

23 and then it goes out through the tute steel; you have a 24 one-inch plate up against the tube steel on the outside, l

25 then you have your nuts. So what do you see? You see a l

4  :  ?!n. CHEN: Was this done in Unit One and Unit Two, or--

1

'5 i~

l nit One in the only one I worked in; 6 , I did not work in Unit Two.

7l MR. CHEN: Can you identify any hangers or areas or  ;

S rooms where this condition might have--

9  : I worked between 860 and 905. I had all 10 of main steam; I had all of feed water, the main feed water  ;

11 in Reactor One.

12 MR. CHEN: Would this be all the main steam lines?

13 I had all the big main steam.

14 fir. CHEN: On all four loops?

15 No, just on 860--between 060 and 905.

16 t1R. WESSMAN: In the Reactor Euilding itself?

17 .

Right.

j 18 MR. WESSMAN: How, a minute ago you said you thought f, 19 as many as 50 percent of these Richmond inserts--is that the i

i 20 proper term--were incorrectly installed. Are you talkine 4

~

n 21 abc ut 50 percent of those that I!allis Bogart was involved I r

22 in or 50 perrcent of all of those? ,

23 .I'm talking about 50 percent of all 24 Richmond inserts were installed improperly. I would say I 25 as much as that, because I was involved in feed water, I was:

i involvcd in safeguard, auxiliary, turran, and they were all '

l 2 j the sane. .

3 MP.. WESSPAM: Mow, that's a large number, and obviously a we're again stuck with trying to pin down some specifics

.- r 5 like we'vn talked before , I need some sugaested areas l

Obviously if we go pick ten and don't i 6 .,

where we go look.

- find any, we haven't looked in the right place possibly. i 8 Can you give us some suggestions of some real good examples 9 if we have to go actually look for then? ,

C Just between me and you, if you went 10 33 and picked ten, eight of them wouldn't be wrong, on Richmond inserts. At an angle other than what, if I'm not mistaken, 12 13 was six degrees, we were allowed out.

MR. WESSMAN: Let me be sure I understand you. You're 34 saying normally the bolt should sit exactly straight out l a.

fr m the wall--

16 Ninety degrees.

37 MR. WESSMAN: --90 degrees angle between the bolt and j 18

the wall. If it varies by more than six degrees in either 39 i direction--

$ 20 --

I think that's what we vere allowed; I'rr not real sure.

MR. NESSMAN: All right. If it varied by more than i

six degrees, you think it was out of specification then.

I Acc rding to specs that I was taught.

9 I nn, gjSSimN: Your suggested place that we would loch l

i 2 i for examples is on this 860 to 905-foot levels of the l Reactor Building where you had actually seen some of these

- 4 that were incorrectly installed.

5 Well, I never actually seen the anchor i

6 . installed incorrectly. I'm just saying when I screwed my--

I when I screwed my anchor bolts into the walls, Itwould say i

6 eight out of ten were not within six degrees. We heated 1 i

9 bolts, we put a nut on the end of a bolt, and- took a sledge i 10 hammer and smacked it in order to make the 90 degrees so ,

11 we would not have to burn or drill a hole oversized on the l I

12 inside to allow for the outside to look good. i i

13 MR. WESSMAN: Are you saying that if we went and looked!

14 today, we would be very hardpressed to see whether any of 15 them are out of spec or not?

16 -

Yes.

! 17 MR. WESSMAN: Because you heated.them or pounded them  ;

i i

IS with a hammer to bend them straight. l 19 I would say eight out of ten of then. f 1

i 20 MR. WESSMAN: Do you know whether there are any NCR's

! 21 or documentation on the ones that were crooked?

22 No, because you got to realize you did u J 23 not call an inspector until the actual hanger was up, and 24 what that inspector saw was the finished product. IIe did 25 not see how that bolt was put in there or whether it was

..~

s

• 10 I beat, heated or otherwise. What the inspector saw was the 2 finished product with the plate behind it, the tube stocl, 3 the plate in front of it, and the actual torque of the 1 plate.

5 MR.;WESSMAN: Ithinkinthisearlier[ you i

6 also talked about how they would sometimes cut the hole on 7 .

the back side of the tube steel out so that it would fit a 8 slightly croched bolt. Would that evidence still be i

9 present? .  ;

10 On the actual ones that I found, no. -

4 11 MR. WESSMAN: What happened?

12 I fixed them. I heated the bolt, I.

13 straightened it out; I beat the bolt, I straightened it l 14 out. j l

15 MR. WESSMAN: So you weren't involved in actually  !

i 16 cutting these enlarged holes in the tube steel. You I i

, i .37 straightened the bolt instead of cutting holes in the back l i 18 of the tube steel.

3 i

19 If I ever caught one of my men cutting i 20 a hole in the back of tube steel, I'd have fired him. There I

j 21 ain't no doubt in my mind. '

i ,

MR. WESSMAN:

Did you actually see some situations where these holes were cut in.the back of the tube steel?  !

23 Yes, I seen--well, wait a minute. I 24 25 seen the results of it. I did not actually see the tube

11 I steel being cut, but I seen the results of it the next 2 morning. Hollis Bogart was general forer.an on nights.

f 3 j So when I pulled the particular hanger off, or hangers, that-4 i I'm talking about and you see a three-inch hole in a six-i-

5 inch piece of tube steel, you report it to your Gold Fat, 6 iI which was Raymond Ecbert, and you're told to shut your 7 mouth. This is what I'm talking abcut.

8 MR. WESSMAN: Raymond Ilebert said this?

9 Yes. .

10 MR. WESSMAN: Is that A-b-e-r-t or something?

11 .

. No, it's F-e-b-e-r-t or something. I?e 12 pronounces it A-bear. It's actually Hebert, but he pro-13 nounces it A-bear.  :

14 MR. CHEN: Are you saying that about 80 percent of all 15 the Richmond inserts were outside the six percent tolerance?-

16  :- Well, I would say if you checked eight i

~

17 out of ten you would find 50 to 80 percent out of the six i i, 18 percent--we were allowed six percent--or six degrees is what

19 we were allowed, six degrees out of tolerance. Okay. You t

i t

i 20 take a 90 degree wall and you go six degrees one way or the l

i 21 other, I would say, yeah, I would say 80 percent. There i 22 was no way that they were within six degrees. l 23  !!R. CHEN: Not all of these that were outside of this six-degree limit had holes enlarged in the back of the tube 24 25 steel against the wall. .

6 , MR. CHEM: Okay.

7 What.I'm saying is-give r.e a piece of 8 scratch paper there--

i 9 MR. WESSMAN: Let's go off the record for a minute l 1

10 while we're sketching and drawing.

11 (Off-the-record discussion held.) l i

12 MR. WES S.9.M : Mhile we were off the record, we were l 13 sketching a diagram of how the Richmond inser'ts were 14 installed in the wall and how these holes in the back of a 15 . tube steel for pipe support would be invisible to an i

16 observer once the installation had been c:omplete. Paul, i 17 go ahead with your questions.

j 18 MR. CHEM: Can you identify for us any hanger that has 19 this problem that you are aware of?

20 Not really. Like I stated before, my l =

l f 21 shack had all the hangers that were wrong, but I've been E

i 22 g ne f r two years and there's no way--they have covered-- i i

23 y u-all got one problem and I'll keep stating it and I'll.

24 keep 9tati.ng it. You-all bring this stuff up, andyougivef l

13 I  !

there from you-all's organization and let hir see what's 2 going on--because I talk to guys every day. I talked to a 3 guy Idst wcckend. The samE stuff is going on daily, and

- 4 until you-all put a son-of-a gun out there and find cut I

3 what's going on, you ain't going to believe a damn thing 6

I'm saying or anybody else is saying.

I MR. NESSMAN: Are you saying right now we could probably 8

see some of this sort of thing happening over in Unit Two--

'9 If you-all put somebody out there--Unit 10 Two is a joke, man. Unit Two is a joke. I went over'there 11 and watched people do things that you wouldn't believe.

12 Until you all put somebody out there and see what's going 13 on--because they'll hire anybcdy. They don't carc what you 14 are; they'll hire you.

15 MR. WESSMAU: Okay. Let's go on with the next 16 question. If you've got anything more on the hangers--

t I 17 MR. CIIEN: This next question concerns your allegation

.i 18 that lugs were welded to stainless steel lines without 19 purging with an inert gas. Can you give us any particulars I

l i 20 such as the line number or support number or anything like g -

t i

21 that for us to--

22 There's no way I can do it. I seen it I

23 done: :I seen it done by the welding foreman out there, Joe o4 Gray. I seen Joe Gray weld lugs on a line. In fact, I l .

! 25 held the lugs on for him on 832 elevation on a stainless l

l L

14 I i steel pipe.

2 ; MR. W.SSMAM: Any recollection of what system it was?

.t  : Man, there's no way. You're talking 4 l two years; I don't remember them systems.

5 MR. WESSMAN: Do you rer cmber how big a pipe it, was?

6  : It was a three- or four-inch. I'm not .

L__. '

7 l real sure on that. It was a three- or four-inch lin,e on S 832 elevation, which Roy Estes was in charge of. He had l

9 a bunch of lugs that were down there that were malfunction

o and the whole bit. We covered them up with Joe Gray welding gj because I held the lugs on for him.

12 MR. WESSMAN: Was this shortly before you were termi-13 nated out there? Do you remember the approximate time-14 frame?

I don't remember the time; I don't.

15 16 MR. WESSMAN: Any other suggestions for us on the i

j g7 welding of lugs that we might look at to,try to find some x.

IS individuals or timeframes or any unusual incidents that

_i 19 might come to nind, or an NCR that was filed that might I

i 20 help us find something?

l* 21 u

- I can't. I wish I could. I wish .I could name dates and everything else, but I can't do it.

22 MR. CHEN: You mentioned a few minutes ago that from 23 some of your friends that some of the kinds of activities

,g ,

that you're telling us about is going on in Unit Two. Is

15 I this the kind of thing that's going on now in Unit Two?  ;

~

2 Yes: yes, it is. It's the same thing.

3 I You've got pcople that are unqualified doing Uni t Two.

I t  :

4 You've got rebar people, form people, and it's been--the  ;

I a man in charg~e of Unit Two when I left there was a man that 6

stated--a'nd I stated it to him before--was a man that looked!

7  ; at one of my blueprints on the main stcan hanger and said, 8 " Man, I don't understand how you can even do anything like 9 that," and two weeks later he was a general foreman over 10 Unit Two in pipe supports. This is the type of people you 11 got out there. Ycu got the same people out there that was 12 out there two years ago. They are unqualified. There's 13 no way in hell that they're qualified to put up a pipe 14 support or any kind of steel support.

15 MR. CHEN: I have no further questions in that area 16 unless you do.

I 17 MR. WESSMAN: No, I don't. Let's pursue your questions i 18 on the main steam line.

19 MR. CI!EN: I was looking through your- --

snd 5

i 20 some of the interviews that were conducted with you on this

/

21 business about relocating the main steam lines. I'd like 22 to get as much information as I can from you in order to be 23 able to investigate what happened. Tell me, this is the i

24 main steam line in Unit One is that correct?

25 Yes.

6 MR. WESSMAM: Let's go off the record and let's draw 7 a sketch of what went on.

8 (Off-the-record discussion held.) .

i 9 MR. WESSMAN: While we were off the record, we 10 developed a couple of sketches of the configuration of the 11 main steam line installation showing where the permanent 12 line was located.and the permanent hangers that Mr.

13 Messerly was involved in the installation of. We've also 14 identified where a temporary connection ~near the steam ,

15 generator was made for flushing purposes. Go ahead from .

16 there with your questions, and let's describe where this ,

I i i 17 line moved when they cut it again, if you woul_ f j 18 _

Well, the line was moved six to twelve

19 inches from when they cut it loose. I was there; I  ;

i \  ;

! 20 witnessed it. My general foreman told me to get my people '

l j 21 off that floor on account of the whip restraint the steel 22 has, and get them off that floor between 860 and 905.

l 23 There was also a Gold Hat there that had the polar crane l

l l 34 tied to the top of this to pull it into position.

25 MR. CHEN: Just a moment. Can I point out at this l

I

........__..&__m 17 1

l point that pointed at the junction between the i

2 i 32-inch r$ain steam line and the smaller diarcter flushing 3 line. Go ahead.

4

, g And my gerieral foreman told me to leave 5 the floor and get all my people off the floor on account of l

6 the strain that pipe was in.

7 MR. CHEN: I believe you: stated in[ that 8 the line, the main steam line, was off'six inches 9 vertically and four inches horizontally.

I i

10 Right.

i 11 MR. CHEN: What was the source of that information? j

~

12 I The source of the information was the 13- pipe people themselves, and a man was down there with a 14 come-along pulling this thing over.in position. Ron McBee j l

15 was the' foreman on pipe that made this change. I can't 16 remenber the general foreman. Ron McBee was the man that l

• l 17 caused this. They took'come-alongs and they took the over-i 18 head polar crane and pulled this thing into position.

The l

4 .

19 tonnage was something like 40 or 50 ton to pull this thing j l l I i i 20 into position after it was cut. We had to move approximately 3

i j 21 four hangers, which I can take you out there and show you ,

, oo right now, that were moved.  !

s l-23 MR. CITEN: Were these hangers on the main steam line?

24 These hangers were on that stean line, l

1 l

25 on that expansion joint, that we had to move because they

.- l

• 13 . l I were out of loc'a tion. T'n talking about a hanger that wo 2 spent three or four weeks on just wolding up.

• l _ _

3 MR. Cl!FN: Did you happen to see which hook on the polar crane was used during this operatio'n?

~~

a 5 The big one.

i 6 MR. WF.SSMAN:  !!ow did you know it was about 40 tons on the polar crane?

~

8 They had a gauge on it.

9 11R. WPSSMAN: And you were able to see the gauge?

10 _ They had a gauge on it, a round gauge;

j it showed the tonnage pull.

12 MR. WESSMAN: This is a gauge--it must be a large gauge 13 that's visible to people standing on the floor.

I 14 ;It's, oh, 24 inches in diameter; or 15 bigger; cr smaller; I really don't know. ~

i 16 MR. NESSMAN: I understand.

I i j MR. CHEU: Let me clarify- get sonething straight.

37 In l i 18 some of your documents that I have reviewed, it indicates

39 that you've said the load might have been as high as 85 i  !

,,0 tons, t t

r  ;

I g  : I really don't know what tonnage it was.

I'm just guessing. I'll just put it to you this way: I've!

23 been in steel all my life, and you don't pull steel in tonnage and expect it to hold. This was also done by a man

,, a. that was fired by another man five years prior to comanche i gs . e m -. eeen e we** **** esp-e =essust e* G a ._ ,.e-===eg mee... - _ _ * ,

14 l

.. I 1

l Pcah, because he was incompetent: the Gold !!at of the i

2 i Pipe Dcpartment out there right now.

3 MR. CHEN: I'm a little bit confused because I think I

4 in some of the documents and affidavits you mentioned 3 ,

temporary supports. Nou you're saying that they're 6 permanent supports. Can you show me on this sketch roughly where these supports were?

! 9 S [-

Mo, I'd have to go out there and show '

9 you. I'd have to go out there and show you p_ermanent 10 supports, the ones we moved, the ones we had t> move, and 33 the whole bit. See, they have--they got a spring load

/

I 12 support, you got a support that keeps from going longitude 13 and latitude, and you have all these kinds ,of supports.

14 The support that we had to move on account of the pipe being g5 in the wrong place when they put the polar crane on it, we 16 had to' completely revise that; we had to completely rebuild i

. l.e that. Charlie Copeland fired the Gold Hat that was in g gg charge of pipe four or five years prior to Comanche Peak

39 begause he was incompetent, and this was a Cold Hat out 1

20 there. I can't remember his name now; I wish I could.

, MR. CHEN

Ile fired him on some other job other than i* ~

,, Comanche Peak?

-, l Right; for incompetence.

23 l  ;

MR. CHEN: flow much adjustments did you make in the hangers? Can you remenber that?

25 i

n, - - .

~

F _. 20 1

What do you nean by adjustments?

2 MR. WESSMAN:

You had to move several honocrs. Did 3

l you move then like three or four inches or are we talking

~~

.2...--

I a relocation that may involve several feet, or just--

5 .

No, we're talking anywhere from three .

6 inches to ten!nches i to a foot, after the pipe was through f 7 the concrete: and you don't put a bind on steel like that. I 8 MR. CHEN: Can you tell me how many come-alongs were 9 used? .

10  : About four.

I1 f1R. CHEN: Do you know what capacity these cor Nlongs 12 were?

13 I did, but it's been a while. But they e .

14 had a guy out there named Rex Broom that would make four of 15 me and you combined, and he put an eight-foot cheater on the 16 come-alongs to pull this pipe, and I'm talking about an i

i 17 expansion chamber, into position. If you think I'm kidding 18 you, go out there and talk to Rex Broom.

{ ,

i 19 MR..WESSMAN: I'm not too good on cone-alongs. Are i

i 20 there standard sizes, like one ton--

f: 21 -two ton, three ton, four ton, five 22 ton; but you put a cheater on them and you can get a lot 23 more.

24 MR. WESSIIAN: Were the cone-alongs being used likely 25 to be four or five tons or one or two tons?

2L I _I'd say four or five ton.

2 !i MR. MESSMAN: o}:ay. l 3  : With eight , ten , twelve-foot cheater.

. 4 , As I told you before, go out there and see Rex Broom.

1 j 5 . ,

MR. CHEN: Just to be sure I understand what is con- -

6 tained in some of these affidavits, you said the lift was 7

supervised by a Gold !!at, but there were no enc?ineers any-8 where around.

9 There was not an engineen nowhere. I -

10 don't give a damn what they say. There was none, because 11 my general foreman told me to get my people off the floor:

12 there was no engineers; he didn't know where that pipe was 13 going, and he didn't want none of his people hurt.

14 MR. WESSMAN: Uhen this pipe made its move, this was 15 while they were pulling on it and they were making the cut a

16 at tbg joint in the generator; so there was one guy dovm i 17 there finishing the cut, and as he finished the cut, the i- 18 thing popped and moved; is that right?

19 That's how far it was out of stress

! 20 right.

i e

2 21 MR. CHEN: Are you aware or have you heard of similar i

22 inciderits on the main steam line?

23 .

No, not really. I can't say I do. All 24 I know is what happened in Reactor One, Containment One.

25 I was there; I was there on everything.

',' 22 I MR. WESSMAN: Do you know whether they ever did this 2 on any other main steam lines out there?

3 i No, I don't. I can't se.y that they did 4 or didn't.

5 MR. UESSMAN: Do you kno.w whether they ever did it on a l 6 feed line or any other of the big lines but_there?

7

] T7o , I do.not. I went over in Reactor 8 Two and seen the results of what they did with the polar  :

9 crane pulling the feed water and the main ste,am lines 10 because the pipe hangers wouldn't fit; and the welding was 11 wrong and so forth and so on. But that's all I can say. l 12 MR. WESSMAN: They had to do some similar pulls like 13 this in Reactor Two?

14 [ You got to u'nderstand what too)c over 15 Reactor Two: Rebar people, concrete people, people who are 16 used to building forms; they do not know nothing about t

l 17 s' teel. They do not know nothing about the stress of it, j 18 about the tolerance of it, or anything else. This is what

$ 19 you got to realize. It's all a cliquer they're all from i

! 20 South Carolina, North Carolina; and they all come up there t 21 on the same deal. It's the same deal with the general i

22 foreman that did not know nothing about blueprints that I 23 was doing, and two weeks later he wound up as a general 24 foreman over pipe support.

25 MR. WESSMAN: Were you working any hangers in Reactor I

23 I Two where you would have seen any of this?

2 I have not done nothing in Reactor Two, 3 nothing in Containment and Reactor, other than a few pipe 4 supports in two-inch and under. That's all I've done in 5 Reactor Two, Containment Two, or anything to do with Two.

6 MR. Cl!EN: Let ne just try and clarify in my own mind 7 exactly what you're saying. You're saying that this line i 8

was in place; it was cut here, and that was where the 9 flopping of the piping occurred, and then the-pipe was 10 lifted.

~~

1. l 11

{'Right..

12 MR. CHEN: While it was lifted you had to go back and 13 undo some of your hangers and--

14 Approximately five, six hangers I had 15 to redo completely.

16 MR. CHEN: I have no other questions.

l 17 MR. WESSM7di: Was this all done in one overnight shift, j 18 or was this a several-day period this--

19

~7 No, it was a several day, because one

! 20 of the hangers we had to air are completely off of whip s

2, 21 restraints and redo completely, a

22 MR. WESSMAN: Anything else you can think of to share 23 with us.on this? I know you've talked this subject before 2; with the NRC.

W M 25  : No, not really; just that it was done; k

.~

24 I I was an eye witness at it. T'll swear to it in anybody's 2 court.

3 MR. WESSMA!!: Okay, Paul, you have no other questions;  ;

i 4 is that correct? '

I've been in steel work all my life -- I've been a fabricator, I've supervised 2 a shop, and the whole bit.

You've got people out there who do rebar tying.

3 You've got two pieces of steel to tie together with a piece of wire.

This is 4

rebar people, all right? All they've got to -do is to go up there and tie 5 the rebar, and pour the concrete around it.

It's all a hidden object, right?

6 This entire rebar organization and building department has come into pipe hangers.

The entire rebar staff out there is a kind of clique, and they went into the

a hanger department.

out there right new who,, three weeks before he was transferred from scaffold A 10 and rebar said, " Man, I don't knew how in the hell you read these blueprints 11

• g Cwm u Ma i W 47 On February 10, 1983, Messrs. Tony Vega and David Chapman contactech.

in an effort to obtain additional information relevant to his allegations stated in his affidavit dated February 3,1983.

stated he had drilled more than six (6) holes without the proper engineering documentation. He stated he had a log of the locations he had drilled. We asked him for a copy of this information so that we could investigate these items. We advised him he had a responsibility to provide us with this information under the Atomic Energy Act. He refused and told us he was not obliijated to us but was " obligated to someone else."

uggested we contact several people on site to get additional information on improper drilling activities, but stated the information that anyone else could provide would be " hearsay," stating that he was the only person who had first hand knowledge.

stated he also knew of one unautnorized modification to a hanger where, in driling a hole for a Hilti bolt and hitting rebar, the Hilti bolt was cut and welded to the back of the base plate and installed.

also mentioned a 4-inch pipe that " caved-in" in the Unit 1 Safeguards Tunnel, but would not provide additional details.

The above matters were investigated at the CPSES site starting Febrary th, 1983 by Messrs. Vega and Chapman. The persons that mentioned as having knowledge of these activities were interviewed with the following Q i* 2 A ~ .. , . ,

resul t s.

In regard to the alleged drilling activities, none of the persons interviewed' could substantiate allegation on improper drilling activity or provide any infonnation that would allow further investigation of improper drilling activities. In the absence of specific information, no further action is appropriate. ,

In regard to the unauthorized modification, two persons named byh had observed the hanger part first hand. One person observed it when he attended a meeting in Mr. James Callicutt's office approximately two years f

l ago. He was advised that this item had been found in the Turbine Building, i

uninstalled, lying on the floor. He stated that he knew of an investigation that had been conducted where installed Hilti bolts were ultrasonically tested i

j to verify that their actual length was consistent with the length code stamped i j on the exposed end of the Hilti bolts.

I The second person with knowledge of the unauthorized rnodification was the

! person who removed the welded Hilti bolt and returned the hanger to its f approved configuration. This person snted that he knew that .had worked on the hanger prior to it being identified as deficient, but stated he did not se cut and weld the Hilti bolt to the back of the plate.

The ultrasonic examination program to which the first person interviewed was referring, is that described by the Applicants on July 40, 1982. Tr.

1739-1757. On this basis, we have concluded that no further action is n eces sary.

The movement of the 32-inch main steam line mentioned by was investigated. The subject line is MS-1-RB-002 (loop 1). The activity was l _._ . ._

discussed with both craft personnel involved in the movement and cognizant engineering personnel. The line was . moved on January-1671982 under the supervision of the Field Mechanical Engineering Group, and was witnessed by designated representatives. A dynamcmeter, serial number MTE 357, was used at all times to measure lifting force. An engineering representative witnessed and signed-off the proper calibration status, installation and use of the dynamometer throughout the operation. The applied forces are recorded on proper documentation. The line was lifted 3-1/2 inches and moved 5 inches in a 1

. nortnerly direction under engineering supervision. The line is, by design, a

! highly flexible line, and is considered an expansion system to allow for

, , movement during operation. The line is also supported by spring hangers to

. allow for this movement. The lifting points were consistent with the hanger l

j locations to simulate the pennanent support system. The as built configuration I

has undergone stress analysis and the acceptability of the line confirmed.

Accordingly, no further action is appropriate.

An effort was made to identify the "4-inch caved-in pipe" in the Unit 1 l1 Safeguards Tunnel . No such pipe was found. In the absence of more detailed 1 .

information, no further action is appropriate. '

• J. T. Merritt, TUSI, Construction and Engineering Manager

• D. N. Chapman, TUGCO, Quality Assurance Manager

• R. G. Tolson, TUGCO, Site Quality Assurance Supervisor The RRI also interviewed other licensee and Brown & Root employees during the inspection period including both craft labor and QA/QC personnel. ,

• Denotes those persons with whom the RRI held on-site management meetings during the inspection period.

2. Action on Previous Inspection Findinas (Closed) Infraction (50-445/79-18): Failure to Control Inspection Stamps.

As noted in paragraph 2 of Inspection Report 50-445/79-27; 50-446/79-26, the use of numbered inspection stamps has been discontinued and the imple-menting procedure cancelled. The licensee'sjFite Surveillance; Group intervie.nd all QC personnel to whom suchstads .had been issusd and who

~

had failed to return them when the cancellation took'p'1'ce a to' iscertain the reason for the nonreturn and approximately when the stamp was lost or misplaced. Personnel no longer in QC by reason of termination were not interviewed. The dates of loss and/or termination were then used as the basis for an extensive QA records search to determine if the missing stamps had been improperly used. The records search failed to reveal

, any such improper use and the licensee concluded that the loss of the l stamps was attributed to personnel carelessness rather than any overt act.

The RRI had no further questions on this matter, j (Closed) Unresolved Item (50-445/80-01; 50-446/80-01): Class I to Class 2 j Transition Otifices. The licensee has issued Component Modification Cards l 33001 and 33002 which require the installation of the required transition orifices in the manner orginally called for in the design drawings at a location approximately six inches from the improperly sized orifices. The

. improperly sized orifices will be plugged and seal welded.

I

! The RRI had no further questions on this matter.but will follow the implementation of the above Component Modification Cards during routine l inspections.

(Closed) Infraction (50-445/80-01; 50-446/80-01): Failure to Provide l Instructions and Procedures Appropriate to the Circumstances. The licensee i informed RIV, by letter dated February 19, 1980, that their analysis of l 2 f

I l

the as-built mounting of the battery chargers indicated that the mounting provided adequate strength to satisfy seismic requirements. The licensee l also stated that engineering procedures were being revised to require an '

Architect / Engineer review of equipment mounting details in addition to that already required by the equipment vendor. The RRI has verified that

, , .the procedure has been revised and implemented.

The RRI had no further questions on this matter.

(Closed) Deficiency (50-445/80-08; 50-446/80-08): Failure to Report a Significant Construction Deficiency. The licensee informed RIV, by letter dated April 21, 1980, that a review of the reporting requirements of 10 CFR 50.55(e) had been accomplished and that a meeting in the RIV office, as documented by Inspection Report 50-445/80-12; 50-446/80-12, had rendered further clarification of the requirements. The licensee stated that necessary instructions had been given to appropriate personnel in the matter. The RRI has interviewed these personnel and is satisfied that they now understand and will implement the requirements fully. For

further information relative to the " honeycomb" condition referred to in the original finding, see paragraph 4 of this report.

This item is considered closed.

(Closed) Infraction (50-445/80-11; 50-44.6/80-11): Failure to Follow Piping

! Installation Procedures. This infractinge hich'is w discussed fd paragraph 7 of this report, was forwarded by RIV letter T t'ed" April 9; 1980. The licensee reported to RIV, by letter dated May 5, 1980, that an analysis of the reported situation showed that no excessive strain had been placed on the pump nozzle involved. The RRI reviewed these calculations with the NSSS supplier and was satisfied that no damage had been incurred.

The licensee also committed to additional inspection for like items which was accomplished and the results documented. Other situations were found of a like nature and fortunately no harm to equipment was invol,ved. The licensee stated' that piping installation procedures have been revised to make it clear to the craft labor force that piping connections to equipment are not to be made until the piping is supported properly with hangers rather than by simple cribbing.

The RRI observed, during tours of the facility, that the revised procedures had been implemented and had no further questions.

(Closed) Infraction (50-445/80-08; 50-446/80-08): Failure to Follow Procedures for Reporting and Repair of Damaged Electrical Cable. The licensee in-I formed RIV, by letter dated May 14, 1980, that a new cable would be pulled through the buried bus duct to replace the damaged cable. In addition, new cables were also pulled to replace several other cables in the duct that were damaged in the search for the cable originally reported. The licensee also stated, in the referenced letter, that Management / Supervisory Seminars had been held to emphasize the need to follow all project procedures.

The RRI reviewed documentation indicating that eighty-two persons, including 3

electrical department superintendents, general foremen, and foremen,  ;

attended one of two such seminars. Interviews with two electrical crew foremen indicate that they are aware of the procedural require-ments.

i- The RRI had no further questions.  !

3. Site Tours The RRI toured the safety-related plant areas several times weekly during the inspection period to observe the general progress of construction of the practices involved. Five of the tours were accomplished during portions of the second shift. Since the principal effort of the second shift is the installation of electrical cables, primary emphasis was placed on this activity.

No items of noncompliance or deviations were identified.

4. Concrete Repair Activities The RRI observed substantial portions of the activities involved in the removal of the defective concrete in the " honeycomb" areas of the Unit 2 Reactor Containment Building internal walls as discussed in Inspection Reports 50-445/80-01; 50-446/80-01 and 50-445/80 .08;.50-446/80.;q8.

~~ ' ~- -

. . . . . ~

The RRI examined a number of the cavities aftet removal'of the " honeycomb,"

after application of concrete bonding agents, and again after the repair formwork was in place for the concrete pour back. In one area, the sleeve through the wall for the reactor coolant pipe had to be partially removed l

to gain access to the defective concrete. The RRI observed portions of the weld repair to the sleeve to re-establish its orginal configuration.

The welding was accomplished in accordance with the engineer's instructions by qualified welders utilizing qualified weld procedures. As of the end of the inspection period, the entire repair effort was essentailly complete and appeared to have been done in a sound manner in accordance with recognized concrete repair practices.

The licensee officially informed RIV of the above matter as required by i 10 CFR 50.55(e) in a letter dated April 21, 1980. The report outlines the engineering evaluations performed, the safety impact had the defects gone unrecognized and/or unrepaired, and the repair methods to be utilized.

No items of noncompliance or deviations were identified.

5. Major Component Installation Activities During the inspection period, the RRI observed the efforts involved in installing the last two steam generators and the first two Reactor Coolant pumps in the Unit 2 Reactor Containment Building. The RRI observed the 4

1

1 initial preparation of the steam generators for hoisting into the building, the actual hoisting and movement, and finally the setting and alignment of the units on their support columns. Each step was observed to be.in accor-dance with Operation Travelers RI80-369-3400 and ME80-2005-5500 governing the work of the riggers and millwrights, respectively. The RRI also 2

reviewed the steps indicated by the two Operation Travelers with the NSSS supplier representatives on site and verified that the steps utilized

• were in consonance with the supplier's written recommendations. The RRI reviewed data developed by the site field engineers (surveyors) which showed that the generators are well within the established vertical require-ments of the vendor'and that each of the four support columns are carrying approximately equal load. In regard to the Reactor Coolant pump instal-lation, the RRI observed the work involved in setting the pumps on their columns and establishing the pumps into an essentially level position.

The RRI also observed the preliminary installation of two of the Reactor Coolant pipe legs through the sleeves leading to the Reactor Pressure Vessel. These pige sections were carefully handled and placed into posi-tion in accordance with good practice.

No items of noncompliance or deviations were identified.

6. Reactor Coolant Pressure Boundary Piping Installation

L ,

.r The RRI made limited observations of pipint conRonent', handling ,in the Reactor Coolant Pressure Boundary area during the period. The RRI observed two welds in process as follows:

Weld Number: FW-3A FW-20 Isometric: RC-1-RB-026 SI-1-RB-037 Line Identification: 14-RC-1-135-2501R1 10-RC-1-021-2501R1 Welder Identification: AWT and BMK BAG Weld Procedure: 99025 (Machine GTAW) 88025 (Manual GTAW)

Filler Metal Identification: 463870 762550 l Subsequent to the observation of welding, the RRI verified that the welders, weld procedures and weld filler metals were each properly qualified in accordance with the ASME Code,Section III or IX as appropriate. In addition, the RRI also examined the radiographs taken of the welder quali-fication test coupons for welders BAG, BLU, AXC, BPA and AED. These t

5 I

radiographs, which are an examination alternative of ASME,Section IX (the other alternative is prescribed bend tests), indicated a sensitivity technically seceptable per Section V of the Code. The RRI discussed the radiographs with the supervising radiographer who stated that the fuzziness of the radiographs was caused by energy scatter from the source (Iridium

-192). Since the radiographs met all technical requirements of the Code, he felt there was no problem. The RRI agreed that the Code had been technically satisfied, but at a marginal or minimum level and the radio-graphs could be substantially improved by a better technique. The RRI will pursue this matter during future inspections. The above discussed radiographs indicated that each welder had accomplished a weld or welds that satisfied the Code requirement's and were, thus, fully qualified to perform production welding.

The RRI also examined radiographs of the following reactor coolant boundary (Class 1) welds: .

7. Other Safety-Related Piping Installation Activities The RRI observed welder ARI during a period when the welder was working on joint W-5 as identified on isometric CT-1-RB-17 in line 10-CT-1-027-301R2. The welder was working to Weld Procedure 88021 using filler metal Heat Number 463638. The qualification of the procedure and this heat of' filler metal have been verified several times during previous inspection.

Review of the welder qualification records for ANI indicate that he has been properly qualified in accordance with ASME,Section IX.

The RRI also examined the licensee actions in regard to implementation of his commitment to radiograph and repair those field welds in the Safety Class 3 Component Cooling Water and Auxiliary Feedwater Systems that do not require radiographs under the Code. (For more information regarding this commitment, see Inspection Reports 50-445/79-12 and 50-445/79-17.) The personnel managing the program indicated that approximately 55% of the 1842 welds involved have, to date, been radio-graphed and that about 37% of those requiring cepair have been repaired.

The RRI randomly selected the following radiographs for review:

In one instance however, the RRI observed a situation that was of concern in that possible major safety component damage might have occurred which could easily have gone undetected. The RRI found that a pipe assembly, consisting of several feet of six inch diameter pipe, was being entirely suspended by attach-ment to the suction nczzle flange of the Unit 2 Train A Safety Injection pump TCX-SIAPSI-01. Further investigation developed that the pipe assembly would place a torque load on the nozzle.of between 1500 and ,

2000 foot pounds. The RRI found that CPM 6.9 did not provide instruc-tions on this matter to the labor force, although the project Mechanical Erection Specification (MS-100) specifically prohibited such practices.

The RRI notified the licensee of the situation which was in turn followed up with a Notice of Violation dated April 9, 1980.

The licensee responded to the initial notification by having the other installed pumps and valves in Unit 2 checked for like situations. A very limited number of other comparable situations were identified during this inspection.

The RRI identified situation and others identified by the licensee were

, detailed on Nonconformance Reports which were submitted to the component 8

e

1 vendor, Westinghouse, for analysis of possible damage to the components.

The analysis indicated that no damage was likely to have occurred due to

! the static loading on the. nozzles, although had the pipe been of a heavier 4 schedule or longer in length, such damage would have occurred. The West-

, inghouse analysis was reviewed by the RRI who had no question of its accuracy.

The licensee's investigation of the circumstances surrounding the incident indicated that the pipefitters had the pipe supported by temporary wooden blocks or jack stands when they left the work area. These workers 1

were subsequently reassigned to other work and did not return to the area.

In the meantime, it appears that a group of painters were assigned to paint the floors in the area and removed the temporary shoring under i

j- the piping leaving it suspended from the nozzles.

The labor force was notified that this practice must cease and the licensee also revised CPM 6.9 to provide specific instructions in the matter. All of these actions igere consummated during the period covered by this report, and as noted in paragraph 2, this item of noncompliance is con-sidered to have been satisfactorily closed.

Except as noted above, no items of noncompliance or deviation were identified.

8. Electrical Installation Activities ,

,'[

The RRI made a number of observations of electrical cable installations during the inspection period. The primary inspection effort was directed

toward observing the activities of the various cable pulling crews and i toward this end at least five crews were checked. During most of the period there were seven active crews working safety-related cable. Each of the crews observed appeared to be knowledgeable of the prescribed methods of pulling cable and of the limitations imposed by site pro-cedures and good practice. The RRI also examined most of the Main Control Room cabinets and the termination cabinets in the Cable Spread Room of Unit I relative to the quality of the worlananship displayed in termination of the cables. No instances were found in which the termination was less than satisfactory as evidenced by the application of the correct size l wire lug that was properly crimped and tightly installed on the terminal

! boards. The RRI also examined a number of terminations for correct l

connection on the terminals as indicated on the electrical design drawings with no errors being detected. This effort was primarily directed toward the main 6.9 KV switchgear in Safety Train A.

l' No items of noncompliance or deviations were identified.

I l 9. Protection of Major Safety-Related Equipment l

l During the course of general plant tours, the RRI noted that the major

plant components continue to be well cared for as evidenced by space i

heaters being energized and where appropriate, because of on going work, the equipment is adequately covered. The Unit I and 2 Reactor Vessels were noted to be well protected even though extensive civil construction work was in progress in the immediate vicinity. The Unit 1 Reactor Vessel internals were noted to be in their enclosures and apparently adequately-protected as was the Unit 1 Vessel head with the installed Control Rod Drive Mechanisms. ,

No items of noncompliance or deviations were identified.

10. Management Interviews The RRI met with one or more of the persons identified in paragraph 1 on April 2, 3, 9, 10, 15, 18, and May 13 and 29, 1980, to discuss inspection findings and to discuss licensee actions and positions.

iii. For low energy linen, if the clearances in i and 11 cannot be maintained due to ambient thermal expansion, a total clearance of 1/8" t 1/16" on any two adjacent sides is acceptable.

In the use of these deviation values *, when more than one direction plane is involved, the resultant value shall not exceed the deviation value.

7.4 ADJUSTMENT OF HANGERS 7.4.1 Adjustment Prior to Pipe Rigging After erection of a system of hangers, the contractor shall adjust all supports to the design elevation of the supports in the cold position indicated on the drawings after making any necessary corrections for deviation of supporting steel and equipment connections from the design elevations. All constant and variable spring supports shall be securely blocked out witn factory supplied travel stops, and all attachment welding and supplementary steel connections shall be inspected for completion and adequacy prior to rigging piping into the hangers.

7.4.2 Adjustment Prior to Testing and Flushing i

Prior to hydrostatic testing, the Contractor shall inspect all ,

installed permanent hangers for design offset, adequacy of clearance for piping and supports in the hot and cold position, p freedom of rods to swing and guidelines to permit movement without binding, and adequacy of all anchors.

L All threaded components shall be inspected to assure full thread engagement and proper erection of thread locking devices or upsetting of hanger rod threads. If the permanent hangers are not available for installation, the contractor shall be responsible for providing adequate temporary support during the test. Hanger installation and adjustment requirements for

• testing are as follows:

a. Flushing and Hydro-Testine of Steam Lines

1. For steam as the blowout medium at normal operating temperature or less, the deadweight supports (spring and rigid hangers) are required to be in place with all epring hangers in the unlocked and cold set positions.

Thermal restraints (rigid and guide) and moment restraint supporting structures are required to be in place.

ii. For domineralized water as the flushing or test medium at ambient temperature, the deadweight supports are required to be in place with all spring hangers in the supporting locked position. The' moment restraint structure is not required if it is substituted by a temporary rigid support.

iii. For air as the blowout medium at ambient temperature, the deadweight supports (spring hangers and rigids) are required to be in place with all spring hangers in the unlocked position. The moment restraint supporting structure is not necessary if substituted by a rigid support. .

b. Pneumatic Testine and Blowout of Air and Gas Lines Air and gas lines shall be pneumatically tested and blown out with clean dry air only. This is to be done at or near ambient temperature. The deadweight supports (spring hangers and rigids) are required to be in place. The moment restraint supporting structure is not required if it is substituted by a temporary rigid support.

c. Flushine and Hydro-Testine of Water Lines ,

For air or domineralized water as the medium at or near ambient temperature, the deadweight supports are required to be in place with all spring hangers in the unlocked and cold set position. The moment restraint supporting structure is not required if it is substituted by a temporary rigid deadweight support.
