6.2.2 CONTAINMENT HEAT REMOVAL SYSTEMS The Containment Spray System (CSS) is designed to remove heat from the Containment environment following a LOCA, a main steam line break accident, or a feedwater line break accident. Major components of the CSS are the RWST, Containment spray pumps, Containment spray heat exchangers, spray headers, spray nozzles, and Containment recirculation sumps.

O Each unit of the CPSES is equipped with two redundant Containment spray trains, each designed to provide emergency Containment heat removal in the event of a LOCA. This system, in conjunction with the ECCS, removes postaccident thermal energy from the Containment environment, thereby reducing the containment pressure and temperature.

6.2.2.1 Design Bases The CSS is a nuclear-safety-related system and is classified as seismic Category I. The system is designed in accordance with NRC Regulatory Guides 1.1, 1.26, 1.29, and 1.82 and in accordance with GDC 38, 39, 40, 41, 50, and 56 of Appendix A of 10 CFR Part 50.

The CSS operation is divided into two phases, initially operating in the injection phase and then the recirculation phase. Two redundant and physically separated spray trains are provided for the O

1 Q: Please state your name and address for the' record.

4 Q: P' lease tell us a littTe about youi Eapground at Comanche Peak plant.-

5 A: I worked for Brown & Root at Ccmanche Peak for almost f,ive years. -

6 It would have been five years in February 1983. I started out in cabl'e tray ha ngers.

until g 7 I worked' for.

10 In _I was busted back, supposedly for absenteism but I believe for a egea y 4, 11 pookingr,ibstha'weldrodcan. (Iwasn't.) About the end of November 1982, I 12- was, contacted by~ about the waste of materials, and ordering of equip-13 ment for dril-ling through rebar and ' concrete and gifts received by me and others 14 for ordering all the equipment for drilling through the rebar and concrete. I was

'15 told by him that I should turn over thh docu=entation,which I t}old him I had'  ;

16 on the holes I had' drilled in rebar and concrete without having documentation and%

v e Q ,

1 authorization to Ron Tolson. I asked Mr. Vega if I was going to have a job 2 Monday morning; he said, oh yeah, yeah, no problem, no problem, nobcdy's going 3 to know about this. And I was fired, on [Awelder 4 and I were over in the cdntainment building delivering a tool that we had borrowed.

5 and we were fired for. leaving 'our work area two minutes before the first whistle t

6 blew. ,

7 Q: Tell us about the drilWQhrough the rebar you mentioned.

8 A: You know the agticle that came out in the paper about rebar drilling and all that?

~ ~

g _ __

10 Q: The article from the FORT WdRTH STAR-TELEGRMi dated 1/7/83 titled 11 " Cover-up at Comanche Peak is charged" which I3.3. svwn you as being CASE At' tach , .

12 ment 9 to CASE's 1/11/83 Written Argument on issues? " - *

~

13 A: Yes, that's the article. Well, I@ t{e cie. that started the rebar -

14 drilling. I'm.the one that ordered the material to, get it, and. I'm i;he one -

15 .that broke in. . H.e used to work 16 for me. I went t ho was my imediate supervisor and told him 17 that I wanted something besides what I had, that I didn't want to go to the 18 next' Brown & Root job and say I knew how to drill holes through concrete and 19 rebar. And I got out of it.

,e 1

20 Q: They were buying'these -- what do they call them -- rebar eaters?

21 A: Yes, from Orillco Manufacturing Company at their branch office in 22 Miami, Florida. I told Mr. Vega that I had taken a trip to~ Miami, Florida, 1 .

l 23 watched the Dallas Cowboys play; that I took about $300 down there with me

~

l 24 and came back with mor.e money than I'took;- that me and my wife took an all-

~

25 expense paid' trip, were treated to the best meals and everything else by l

. i .

~

- fu .

• 1 Orillco Manufacturing Co.; and that I had been sent $400 from them as a gift 2

or whatever you want to call it through Western Union. All this was because 3 I had ordered those parts from Orillco. I told him I, also knew for a fact that 4

another man had t-eceived two motorcycles as a gift because he ordered Drillco 5 parts . And a week later I was out on the street.

6 Q: They're not supposed to use rebar eaters onsite?

7 A: Well, they 'are and they aren't. If they've got documentation and 8

authorization from engineers, it's all right to use Shem in certain parts of 9 the buildings. If there's no documentation for it, you're just not allowed 10 to use them, period, because it'll cut through anything. It's that type of 11 drill . .

~

12 Q:

But if they cut through any of the reba'rinlhe wall, they're suppo. sed 13.

to be, careful n'ot to damage the rebar any more, _than they have to and they, have 14 to get approval .before they do it, is that right? -

15 A: i Right. You've got to have approval and you ve got to have documentation 16 by engineering. And some of it was done with.out having any kind of documentation

17 or approval. '

'18 Q: Did you do some of that too? '

19 A: Yes, I'm the one that originated it.

I'm the one that ordered it from

!O Miami.

It was over $50,000 or so when I ordered the first order of equipment

) throug '

2 Q: And he was are of it and approved it?

!3 A:

He approved the ordering of it and what it did because it was like 90%

4-difference in that and Hilti bolt. What it amounted tio is Hilti organization 5

came in there with the same thing, but basically you had to drill more holes e

s. .

- 4- -

• c.

1 in the wall and you $1ad to mount Hfiti bolt drills to hold this particular app 2

tus they had; and Drillco had a vacuum plate where all you had to do was plug 3

it in the wall and hook it on the wall, and drill it. In man hours, it saved 4 a lot of time. '

5 Q:

But were things done that weren't supposed to be done they way they 1 6 were done? -

7 A: Well, that's sort of what it amounted to. I've 'got documentation for

'3 the past ils years when I took it over, and later made foreman 3 over it.

10 Q: Ycu've got documentation on .that?

11 A:

I've got about the holes that I've drillad and was ordered to drill 2

b ecause my job was on the line. I've got about' a year-and-a-half of documenta-3 tion. It's like a hiary. -

I kept a daily Trg"on-what, percent I cut out of the 4

rebar, wh'en it was done, the date, a d everything else.

And what I was. told 5

by general foremen and three stripers (which are next to a gold hat, which is 6

a superior general foreman); I was told to do-it or go out the gate. And this 7

is the documentation I wast 'old to turn in to Ron Tolson.

3 Q; Did you turn it over to him?

A: No, I did not.

I still have all the documentation, i

~2 eater to other people. I can't swear what they did with it, but they could 3

have used it to dril.1 holes in the concrete and' rebar without anyone knowing 4 l or authorizing it and without documentation.

I dan't know what can be done about the waste, the materials, and the back-stabbing that goes on at Comanche Peak.

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? A1,1 they've got to do is to go up there and tie 5 the rebar, and pour the conIrete around it.

It's all a hidden object, right?

6 This entire rebar organization and building department has come into pipe hanger 7

The entire rebar staff out there is a kind of clique, and they went into the 8

hanger department. They suddenly became hanger geniuses. There's one man

g out thgre right now who, three weeks before he was transferred from scaffold 10 and rebar said, " Man, I don't know how in .the hell you read these blueprints 11

-- I don't know~how in the hell you can make these things (pipe hangers)." ~

12

' And as God is my witn'ess, three weeks lateF this' man was a General Foreman cver pipe hangers.

' 13 ,

He was a general foreman next to a gold hat over pipe hangers.

14 He suddenly . knew all about pipe hangers. He sudddaly ' knew all about steel.

15 And here was a man that has done nothing but concrete and rebar all his life.

he belongs to the building department out the e, because he is one o

pipehanger crew until he left his employment with B&R in

alter hangers even though it was very time consuming.@ said gping a torch was " strictly forbidden", and that he never used one.@ also said he was not present nor was he aware of the reloca' tion of the main steam line using the polar crane in Unit I. .'.
