n. s. . e,. 5 INTERVIEW WITH AGUAYO e i . SHACKLETON: This is an interview of Mr. Philip A. AGUAYO. Mr.AGUAYO] is an electrician working for the Bechtel Power Corporation at Unit il at Palo Verde Nuclear Generating Station., Present to conduct this interview from,the J,_. Nuclear Regulatory Comunission is E. J. POWER and O. C. SHACKLETON, investigators from Region V. Mr. AGUAYO, do ,n ~[. we have your permission to log this interview on tape? c AGUAYO: Yes, sir. SHACKLETON: And, as I understand it Phil, you would like to have a copy of the, uh, transcript.from this tape, is that correct? a AGUAYO: Yes, sir. i ~ SHACKLETON: 0.K. The Connaission will furnish it to you and I'll mail it to your home and be patient with us in time; it will be i a few weeks. AGUAYO: 0.K. '..~; i fy: ~SHACKLEION: 'O.K. Phil, what I want to do is go through this list of -j W'A i allegations and find out whether or not you had any l similar experience or know anything about them or can

- s 1 4 to - 4 SHACgI.ETON: 0.K. Now, see you,e been here since, uh, only'1-1/2 y.' years, uh, you'll cover a period of time... the next d issue is on improper installation of high voltage 4,. termination and what I'm talking about here is the use of some of these materials you guys use to make the terminations like Scotchf111, and I understand that ~ approximately a year ago, two years ago, they were using this material on some of the terminscions and found that 'it bled.because of the intense desert heat out here, and so they've 6 sed another material. They use 130-c. It's a vrap. Is that what you're using now? J
U. \\ ( ,r
- v..,
.9 AGUAYO: Oh, I don't ... I really don't... see, we have all these little specs on different motors and different areas, and when they give you a card like on the motor ~ over here, you check out your specs,'you know, 'cause you. - you use different things and sometimes, you know, like a year age or something and you'd.be using such and such and if they'd say no, no we're not using that no more, we're , 91
- v using this, so uh...
pH W.^ So, whatever the current specs are, yeah. m' POWER: ... and then we're updating them 'so that is, that isn't AGUAYO: good enough, we're gonna use this now. POWER: Teah. 0.K. Phil, the next issue is concerned by some people where - SHACKLETON: you do terminations like onto an electrical motor, have .you done any of thoset AGUAYO: Right. r. }Q. And I'm talking primarily about safety class motor, not. p,' 5BACKLETON:~ tQ, wh, smaller ones but the larger motors that are involved A in Class Q systems where you may have on the pockerhead a
- c. w.
-e 6@ one-lug bolt connection off the motor and on your field 17 e u f': A F cable you've got a two-bolt lug. Do you follow me ~ allright? %g.,; C-p ], AGUAYO: Teah. r,.s w.. c.,. SHACKLETON: When,you... I AGUAYO: Two-bolt. i !~ e
\\ ( a 10 i l SHACKLETON: ... when you go to connect them, have you done any of those? AGUAYO: Uh, if I remember correctly, everything I've done they match right up. SHACKLETON: So you've never had a two to a one? v._1 g. -AGUAYO: No, I don't think you can do that.
- f,'f. '
SEACKLETON: 0.K. AGUAYo r - I'm pretty sure they came out and said we couldn't use that. SHACKLETON: The next issue is getting your opinion 'and observations on your QC inspectors that work with you people'to inspect your work. From your observations, do... are... do they do an adequate job? AGUAYO: Here then adequate. See, if you make a mistake, they're going to find out about it. m. 'c. .+.. 1 SHACKLETON:
- k. ;
Do you feel that they, they are well enough trained that' ,7 . ~ 3.q,. they know what they're doing? Do you feel satisfied? " " gr AGUAYO: Right. They do a real good job. v: ( SHACKLETON: Good. Now the other part of that is that we've had an allegation that some of these people are intimidated by i* foremen and superintendents in construction to where they'rt, they're afraid to enforce what they think they should do, like hang a red tag and then have a foreman come along and tell them to take the damn thing off and J
\\ k ) 11 s i the guy does it because he's intimidated by. it. Have,you ever observed or know of that to take place? i ACUAYO: Never. They're king pin out here, you know, they're w (unintelligible) main man. SHACKLETON: Do you feel then, that QC operates freely s.s quality control without being subject to construction? 2h' i er 1 AGUAYO: Right. Yes, I do. SHACKLETON: Have you done any high pot testing? AGUAYO: I actually have. I've been forenan on it, but as far as hooking up all the things, f. haven't. SHACKLETON: ' - Have you ever heard or observed excessive high potting on the cable? We understand, again as I explain to you, Gene and I are not electricians or electrical engineers, but we understand from the alleg... from the alleger that Anaconda, in their specs for their cable, states they can only high pot test it once. If you do it over once ~.c ('2... - that... 27 i - 5:. w 1 7 i i (end of tape) ..q ' y-::: .'r SRACKLETON: Phil, have you ever worked on, uh, the installation where
- , j
'you, you have conduit that comes down to a metal cabinet where'you terminate maybe some kind of a control cabinet, >) when you're using conduit and you have 0-rings where you f -. got a fitting that, that has threads and it tightens down [e.~ so that you have water-tight integrity.? ACUAYO: Uh, I'd inagine so, 'cause they're all over out there. h-
\\ k 3 ') 12 SHACKLETON: Yeah. Have you ever worked on then yourself? J AGUAYO: I would say' yes, I mean, I don't know... { t SHACKLETON: Have you always, can you recall, have you always had 0-rings available when you needed them? AGUAYO: Well, we don't install them, but the guys that run the pipe do. SHACKLETON: Yeah, 0.K. So you've never done it yourself. Well, I, I've ran pipe out here before... l AGUAYO: I ~ SEACKLETON: Yeah. AGUAYO: ... and I have intalled them. 1 SHACKLETON: Well, the allegation was that there was a period of time here for about six months in which Bechtel didn't have q 0-rings available and the men were told to go ahead and do the piping without them, which they did. AGUAYO: Every time I was on piping we always had them available. ?g i ,-a. g. ~ SHACKLETON: The last area, Phil,1 vant to talk to you about has t nothing to do with electrical, but it's a problem that we face in the country today and in many walks of life and I many places and that's the use of controlled drugs on the site and we've been given information relating to the use of and sale on this site of marijuana, hashish, ampheramines, uh, cocaine. Have you' observed or know of this type of traffic on the site? L J
\\ Q 1 13 AGUAYO: I've heard of it, you know, but uh... SRACKl.ETON: Is there any particular' areas in the plant where a lot of pot has been smoked? AGUAYO: The only place I would say about that would be out in the parking. lot. You know, like prior about three years ago. [ you know, when the thing was going big you had a lot of sw.. 2- ; people out there smoking pot. You could smell it, you know. i SEACKLETON: Uh-huh. .AGUAYO ... that's one thing... I've never been around anybody that's done that 'cause.I wouldn't even work with somebody like that, you know, it<can. endanger'you.and' endanger somebody else. SHACKLETON: Well, that's a real concern that we have, for the... everybody, the public in particularly. All they have to know 1f that we've got a drug problem out here in addition y to all the other allegations and we're interested in, in y curtailing it, getting it out of here because not only [j_, - drugs, but alcohol. If a guy is inebriated, uh, he could l. hurt somebody, hurt himself and he isn't going to do his Y ~ work very well. And if he's working on safety-related 'k work, uh, no one wants that, no one would want a surgeon or a dentist to be crocked when they're at work now. N AGUAYO: That's true. ,.7' $[ SHACKLETON: 0.K. J... the only other question I, have, Phil. Is g-there anything that you've observed here at the plant that 4 r+
( ( 9 14 you feel that the Nuclear Regulatory Commission should give it some special attention? AGUAYO: The only thing I'd.like to see, like when they get Unit 1. going, some monitors out there. You know, I don't know how they're going to do it once they get Unit 1 on the line,'but SHAC EETON: They put monitors all over the count'ryside. AGUAYO: ....for my own safety, you know, I'd like to have a ' sonitor available whenever I wanted.to walk around here. SHACKLETON: They have, they have monitors all around for miles... AGUAYO: But let me... SHACKLETON: ... and, and on zones, it's all zoned off. And they have, they have monitors on all the, uh... POWER: As far out as ten miles from the site. SHACKLETON:. Teah. i.S N POWER: ... they go out quite a distance... I bet... we've got !c6 different people in our region (unintelligible).
- v SHACKLETON:
We're not health physicists... they're health physicists.... Yes, I'm not a health physicist, I'm a physical security POWER: invesggator type, and we've got engineers, nuclear l engineers, mechanical and all that, whatever... anyway, e
( ( l 8 ') 15 the health physics side of the house does do that, uh, start-up takes a long time, uh, they really couldn't have a problem, they could have, I, I'm not trying to belittle the situation. It could be serious, but because of the tests that they go through, they have a gradual, what is called a power ascension. They're... it's like turning on a water f aucet, you turn it on a little bit and there's going to be a little drip. Well, if you were working in. the area and it's a little drip you can't get wet, 0.K. and then they start turning it on a little more, they go 10%, 20%, 50%, and then they are allowed to go up accordingly so far. Now this goes over a period of at ~ least a minimum of probably six months to.a year before they ever reach a point where they start producing power to sell and during this period of time they have to meet certain criteria, in all the testing'so it is a controlled situation, it is well tested. But when you have a question, yeah, make sure you ask anytime and don't forget they're'... there's three NRC onsite all the' time, right now. They're three engineers. Two of which are start-up engineers, that's where their deal is and they might, if you've got a question or concern, you know, please ask them... bi - c. I would like to know before they start Unit 1 or L" AGUAYO: anything... SRACKLETON: They have... they're required to... I would like to be informed about what they are going to AGUAYO: be having cut here. r PO**TR: Yeah.
( ( l s. ~; 16 AGUAYO: Cause, you know, I, you know, you're supposed to work safely, you know, I'm kinda... SHACKLETON: Uh, most everybody is. That's why we're here. POWER: Maybe somebody else will say... Well, maybe they, well, they believe an electrical installation is improper and if somebody has a question and they get to the NRC, I guarantee you somebody is going to come and look at it and make that determination. Now whether. or 'not you believe the NRC that's another problem, but I guarantee you we will ge.t the best that we have available that we can get to go to the 9th degree to determine whether or not it's a valid concern, you know, the allegation is true, if correctable, change or.. correct it or.we'll, um, shut it down, it's that simple ~... s r SRACKLETON: Not only that, we have a very expensive mobile laboratory. and they have come here periodically and run tests on, on the systems in the plant and make sure that... POWER: see if they relate to... SEACKLETON: that that they're at proper levels and so on. There's a lot of checks and it's all available to the public to, to know about. AGUAYO: Yeah. SRACKLETON: Is there any thing further you... POWER: Yeah,pI got one before you get going; AGUAYO: Nc, that's about w
(. (- 1 t. gy POWER: ... Uh, are you aware of or have knowledge of any situation where, in drilling cores, they have damaged conduit in concrete valls? Have you ever heard anything, of this nature? AGUAYO: Damaged your concrete? POWER: Yeah. While they're drilling core samples, you know, they get conduit in the process and damage it. AGUAYd: Oh3 No, I never heard of anything like that. SHACKLETON: 0.K. We'll terminate, uh, this interview at this time and it's approximately ten minutes after three. l (end 'of tape) t e e 4 y 4 e.. / e +}}
