5 Present for this interview from the Nuclear
.Regul' tory Commission is E. J.. Power and myself, O.
C.
6 a
-7 Shackleton, investigators for Region V of the Nuclear Regula-8 tory Commission.
9 Mr. Mast, do we have your permission to tape 10 record this interview?
11
~
MR. MAST:
Yes.
12
~
INVESTIGATOR:
Okay, Dan, I'm going to go over m
p 13 the list of concerns that were given to the Commission 14' concerning electrical to obtain from you your comments and 15 experience, and the first one we are talking about termination 16 cards.
And what we need to know is your experi,ence in 17 with termination cards.
18' Have you ever been asked to sign off a termination 19 card for work you did not perform?
20 MR. MAST:
A couple of times.
Nornally, we'd go 21 out and check and see if everything looke,d proper, or do 22 something like that-t 23 INVESTIGATOR:
When you do that, Dan, how do you i
24 fill out the card; what do you actually fill in?
25 MR. MAST:
Well, the (inaudible) I beiieve there l
L k
l.
3
~
1 were new cards made out,:and --
2 INVESTIGATOR:
Were they second cards; was the firs:
3 card lost, do you know?-
4 MR. MAST:
I imagine that's what it was.
You fill 5
it out.like you normally would.
6 INVESTIGATOR:
So you put your name.and your 7
badge number --
8-MR. MAST:
Right.
Date it.
9-INVESTIGATOR:
-- and then~do you put down your 10 crimping tool number?
11 MR. MAST:
Yes.
12 INVESTIGATOR:
Who directed you to do this? Is 13 7
this Keith, were you working for --
14 MR. MAST:
No.
This was -- well, I was on so 15 many different crews I can't remember who it was that --
16 -
I think it was just an engineer that requested it.
17 INVESTIGATOR:
Do you remember the name of the 18.
engineer?
19 MR. MAST:
No.
INVESTIGATOR:
Do you remember, Dan, whether or 21 not it was on a safety-related system?
MR. MAST:
A Q class?
23 INVESTIGATOR:
Yes, right.
24 MR. MAST:
No.
Not the ones that I. worked on.
25 INVESTIGATOR:
Do you remember what areas in the u _ __
'l 4
,-1 plant'they may have been in, or.-what part of the plant?.
2 Whether it was the turbine building ~or aux building or
.3 control: building or the containment?
4
They must'both of them been in aux.
5 That's mainly where.I was working most of the time.
&J 6
~Auxilia'ry.
7 INVESTIGATOR:
And how many times do you feel 8
you've been' asked to do this?
9 MR. MAST:
Oh, this w'as quite a while back; just 10 a couple of times.,
11 INVESTIGATOR:
And were you asked or were you 12 directed, Dan?
?-
MR. MAST:
I be'lieve I was asked.
14 INVESTIGATOR:
Did, by your recall and your 15 experience, were any of the other craftsmen ever asked that 16 J
you worked with?
. 17 MR. MAST:
I heard they were; I couldn't swear to 18 it.
~
18 INVESTIGATOR:
Do you know anyone that we could 20 talk to that may have been?
21 MR. MAST:
No.
22 INVESTIGATOR:
Gene?
. 23 INVESTIGATOR:
You indicated that you normally go 24 f
out and look.
Did you go in all cases?
25 MR. MAST:
Yes.
i
f-o.-
s-5 1
INVESTIGATOR:
Are all terminations both safety-2 related a'd not --
n 3
MR. MAST:
Q -- (inaudible).
4 INVESTIGATOR:
(Inaudible)- indicators.in all cases?
5 MR. MAST:
Right.
We checked that --
6 INVESTIGATOR:
Couldn't you take the other ones 7
off and put these on, or are they more on the same number?
8 MR. MAST:
The tag itself?,
8 INVESTIGATOR:
Yes.
10 MR., MAST:
We'd just leave the old one on.
11 INVESTIGATOR:
Okay.
12 MR. MAST:
It was all beat up.
p.
13 INVESTIGATOR:
Beat up?
14 MR. MAST:
Yes.
15 INVESTIGATOR:
Now when you go out and look at it,-
16-would you de-terminate ~it and crimp it all over again, or?
=
17~
MR. MAST:
No, if it' looked like it had been put 18 in right then it checked.the points, the landing points and'
'19 the color of the wire and the location and --
20
-INVESTIGATOR:
As long as you have no belief that 21 it was in - (inaudible).,Okay.
MR. MAST:
It was just like he'd done it.
23 INVESTIGATOR:
Right.
24 You were never, then, apparently from the conversation, under any pressure to fulfill
--?
-.y y
,-e
1.
MR.. MAST:. Sign?
2' INVESTIGATOR:
Yes.
3 MR. MAST:
Never have been pres'sured.into doing-e
-J
.4 that.
5 INVESTIGATOR:
Our'next area of interest, Dan, 6
relates to the improper splicing:of. quality control, the T
.7 quality class safet? related cables. -Have you ever.known 8
of any situation-or been asked to, splice quality class. cables.
9' Like in the trade.
I don't mean at a termination.
10 MR. MAST:
No.
11' INVESTIGATOR:
Or there's been damage done.to a c
~
12 cable.
2 13 M R '. MAST:
Splicing it without a card,-or --?-
14 INVESTIGATOR:
Yes, without a card, without QC, 9
.15 without an engineer --
16 MR. MAST:
No, I've never been asked to do,that.
17
-I don' t know of anybody that's ever done that.
18 '
INVESTIGATOR:
We have an allegation that there 19-was some damage done.by welding.
20 MR. MAST:
Oh.
21 INVESTIGATOR:
Slag came down, -- casing of the 22 cable and rather than de-terminate it, pull'the cable, the 23 heat shrink tube was, (inaudible) installed in covering up 24' the damaged area and cables were pulled over the-top so you
~ couldn't see-it.
Do you know any circumstance like that?
L _-
q I'
fe 7
1
No.
2 INVESTIGATOR:
Another area of allegation concerning; 3
the, is a violation of1 cable de-termination procedures.
Where
~
~~ 4 -
you' fellows, a craft, de-terminated a cable that.was bought ofi t.
5 by.QC.and then later,
- Startup,
'or someone else, comes along 6
and de-terminates without following proper procedure, the r
7 documentation 'nd so on, and you guys later. find thatiwhen a
8
'you're doing work t-hat somebody had done an improper termina-9 -
tion or maybe not even reconnected it again.
10' Have you ever had any situ'ations like that?
11 MR. MAST:
I heard'a lot about it, and I had run 12 into a couple of them in particular,-I believe it>was p
13 switches and such.
I'm not certain if they had gone through 14 all the paperwork, but I remember terminating one and later-
.15 on seeing it de-terminated going through the right s
16 paperwork.
17 1NVESTIGATOR:
For my own information, Dan, does 18.
that relate to class Q work?
19 MR. MAST:
That particular one was black cable; 20 it was in class Q.
21 g..
INVESTIGATOR:
It was in class Q.
22 Is that -- did that happen relatively recently, or 23 is it some time in the past?
24 4
MR. MAST:
Oh, that probably was.first of the year; 25 January, February.
8 s
c.
- o 1
INVESTIGATOR:
Is it still a discussion among'the 2-journeymen it beinga problem?
You said you heard it from 3
others.
No.
5 INVESTIGATOR:
Because you're starting.to go into 6
a startup phase now.
7'
'MR.
MAST:
Well when they st'arted issuing, going 8
into different tagging procedures and such, they were --
9
.well, people were a heck of a lot'more cautious, and when 10 you get to a O class cable, you treat it like gospel.
You 11 kn6w, because you mess up one of them, and that's just, you 12 know, all sorts of paperwork --
13 INVESTIGATOR:
(Simultaneous discussion. )
14 MR. MAST:
But as far as I know, I haven't seen, 15 you know, something'that can be terminated that I knew, you 16 know, that someone done it under the sly or something.
17 INVESTIGATOR:
Dan, I don't know whether, within 18
- the time frame of your last employment you may have any 19 knowledge of.this next area, but it relates to the improper
\\
N insulation, the high voltage termination. 'And what I'm 21 talking about here is they have a, well, we've learned -- they 22 had a problem with some of the material they were using to 23 close up-a termination; wrap it up, called Scotch Fill.
L 24 The rubber pad -- as I understand, Scotch Fill is some type 25 of a maleable compound that they use to --
- 9 l
v 1
MR. MAST: -I'm not -- I'm not really familiar with 2
it.
3 INVESTIGATOR: Are you using 130 C now?
4 MR. MAST:
Tape?
w 51 INVESTIGATOR:
Tape.
6 MR. MAST:
Yes.
7-INVESTIGATOR:
Okay, but you haven't gotten 8-directly involved in it?
9 -
MR. MAST:
I haven't done it; I haven't done any 10 taping in so long,,I can't remember.
They changed the 11
- procedure on that (inaudible).
They were using (inaudible),
12 I believe, and then they went back to Scotch.
But they 13 sent out a paper to change --
'14 (Simultaneous discussion. )
15 INVESTIGATOR:
Okay, Dan.
The next interesting' 16 point that was given to'us is concerning. terminations like 17 when you fellows run a field cable up and terminate to an 18 electric motor, and the pecker-head on the motor's got a one-
'19 bolt lug.
And I guess typically on the larger cables you've 20 got a two-bolt lug.
Bear with my ignorance, because I may 21 not have it correct --
22 MR. MAST:
All right.
23 I haven't made up that many motors, so --
24 INVESTIGATOR:
Have you ever worked where ybu have 25 a two-bolt lug or the field cable, or the one-bolt lug on C
y._..
j a,._.
y-10
~
i a
1
. hat you had to connect-it'to?
w 2
MR. MAST:
No, I don't believe I have.
I've made 3
up very few motors, and most of them were small motors with 4
fractional horsepo.wer and such. 'You probably refer to the 5
bigger motors.
6 INVESTIGATOR:
Yes'.
Primarily bigger motors.
7 The next issue is QC inspectors.
The QC inspectors 8
that are a's' signed by Bechtel t'o the electrical inspections of 9
.doing it, inspections of the work that you fellows do, by 10 your observations, and experience do you feel tihat. they are 11 properly doing their job and seem to be knowledgeable and 12 qualified to do what they are doing?
p 13 MR. MAST:
Yes.
The ones that I've had come watch 14 me I think do their* job just fine.
15 INVESTIGATOR:
Have you ever observed or even 16 heard of stories among the plant where QC inspectors have been 17 overridden by construction?
By this I mean intimidated, 18 where a guy might want to hang a red tag and a foreman comes 19 along and t' ells them, Get that damn thing off of there, it's 20 all right, you don't know what youre doing?
21 MR. MAST:
Construction intimidating QC?
22 INVESTIGATOR:
Yes.
23 MR. MAST:
No, I don't know that either.
24 INVESTIGATOR:
Do you feel, then, Dan, that from 25 what you observed in your plant QC operates freelp?
11 i
1 MR. MAST: I believe so, yes.
2
~ INVESTIGATOR:
That they are really quality control ?
3 MR. MAST:
I believe so.
'4 INVESTIGATOR:
Independent from construction.-
5 Most of the men -- I'd be' interested to 6=
know how you feel -- you feel you have appropriate time to 7
do your work?
8 MR.' MAST:
More than ample time to do-it.
9 INVESTIGATOR:
So you feel'there's no reason why 10 you guys shouldn't be able to do a qua'lity class job.
11 MR. MAST:
Right.
I've really never run into 12 anything where I didn't have enough time.
They give you 13 time. limits sometimes, and if you don't-get it dong, they 14
~just make a new time limit.
So you've got your own speed
-]
. 15 anyway, so --
16 INVESTIGATOR:
So you feel that you guys are 17 able to slo quality work?
18 MR. MAST:
I c.an speak for myself, yes.
'19 INVESTIGATOR:
Do you work in pairs, Dan, or do N
you work singly?
21 MR. MAST:
On and off probably 50 percent of the 22 time.
It varies.
23 INVESTIGATOR:
How long have you been in the 24 craft, Dan?
25 MR. MAST: Well, since my apprenticeship, i-L
- g...
w-a.:
~

'approximately seven an'.a half years._ I was'close to the. age.

' electrician?'
-+-
_4 MR.. MAST:.Four years.:-
5 INVESTIGATOR: -Have you done any high potting since
[6 you've'been out here?
17 MR. MAST:
Yes.
m 8.
INVESTIGATOR:~
One of the allegations we.have.is s.
9-that in-isome cases that excessive high ' potting on the same 10 -
cable, have you ev,er observed or'heafd of this?
11 MR; MAST:
No.
I helped with two.high pots, we
- 12 :
did - (inaudible).
r:
13' INVESTIGATOR: ~Well, the information we have is' 14 that the excessive high potting isn't being done by the 15 :
craft, but it's being done by some of the Bechtel engineers-16 who didn't.seem to know how to do it or it.was done by s
17
~
Startup who came along and did high pot testing'after.
= 18
.MR. MAST:
Is that right!
19
-INVESTIGATOR:
Construction had already done'it.
20
.Have you ever heard anything'like that?
21 MR. MAST:
I never heard anything like that.
22 INVESTIGATOR:
Do you have any ins'tallations where
- 23 you are working with conduit where you've used O rings for 24 integrity where the conduit comes into a box, connecting box?-
25 MR. MAST:
Are you referring to a fitting like a
f7 V
'13
} {'. ;* ^
v Myers',$ sort of'a brand name,, Myers.--
1 12-INVESTIGATOR:
It might be,'I!wouldn't know.-
3
.What'I'm[ talking.about, andithe way.it's described to me, it's q-
-4 like where you have'a conduit an'd you've-got.a slip ring on 5
it'with thread,cand-you've got thread on the top of the box.~.
to-And then you've got an O ring.that.' acts as a washer that
. compresses to give it watertight integrity to pull'the'.
7 j
'8 conduit-down tight.
8-MR'. MAST:
Okay.
I think I know what you're 10 talking about.
- (Inaudible) connector, a:
connector?
11 INVESTIGATOR:
You'd know the terminology.
12 MR. MAST:
I'm assuming that's what you're talking p
13 about.
14 INVESTIGATOR:
Have you done any installation of 15 -
those?
Now, the area I'm talking about is in the control 16 building'down at 100 foot' elevation.
Have you worked in
~
17 that area?-
18 '
MR. MAST:
Very.little in that area.
19 INVESTIGATOR:
The allegation we have is that for i
20
- one period of time Bechtel didn't'have the O rings available 21 for about six months.
An.d the electricians were told to'go 22 ahead and do the installations even though they didn't have 23 the O rings.
Did you ever hear anything about that?
24 MR. MAST:
No.
25 INVESTIGATOR:
And you've never participated'in E.
p'
~ 14 g..
f S
1
.any. installation like that?
- 2-MR. MAST:
No.
3 INVESTIGATOR:
The next subject, ' Dam, is a 4
situation where you guys have to make'a new penetration, 5
maybe going 1from the wrap-around building in the containment
~
6 or something where you've got to run a new line,- new cable 7
or something, and theyve accidentally drilled into' conduit.
8-Have you ever heard bf any such thing?
8' MR.. MAST:
(Inaudible).
~
4 10
. INVESTIGATOR:
Yes, when they're drilling, taking
' ll (inaudible).you know, penetration, they hit their core, 12 conduit.
p.
13 -
MR. MAST:
I've never run into that or heard-14 about~it.
r 15 INVESTIGATOR:
Talking about that, have you ever 16 heard of an electrician by the name of Jerry Stewart?,Or 17 Jim Williams?
18 MR. MAST:
Jerry Stewart sounds f amiliar; I'm not 18 certain if I know him, though.
s 20 INVESTIGATOR:
There's a couple guys we are trying.
21 to find who are no longer here.
Once they leave here, it 22 gets a little bit difficult.
(Inaudible).
'They were possibly 23 involved in some of these things that we're asking you about, s
24 and we'd like to talk with them.
N MR. MAST:
That may well have been before I came out.
I a
15 I
I 1
INVESTIGATOR:
It could well have been.
2 Last question off of this list; nothing relates
[
3 specifically to electrical installation, but it's one that
?
4 we're concerned about because of the implication it has on 5
the plant.
And that's the use of drugs on the site. I'm 6
- talking about controiled drugs; marijuana, hashish, cocaine, 7
all the various amphetamines like black beauties and.so on.
8 And we're not naive; we've been around the world a little bit.
9 We know we've got it, but we wonder how bad it is.
We're u
10 getting allegations of different -- different people.
And 11 you're on the young side, and it's usually the younger side 12 that knows more about it.
What is your observation?
13 MR. MAST:
I've smelled pot out there.. I can't
)
14 i
say I haven't.
15
~
INVESTIGATOR:
Is there any particular area of 16 the plant where you felt it's been in use more than any 17 others?
Do they have some favorite place as a hideout where 18 they can sit and smoke?
19 MR. MAST:
No, I haven't smelled any in quite a 20 while, but when I did it was, I believe it was up in about 21 the third floor of auxiliary or control.
22 INVESTIGATOR:
Underneath the control room?
23 MR. MAST:
Well, in the auxiliary -- in that area 24 between that and control.
25 INVESTIGATOR:
Have you heard any discussions L
~ x;
- ~
' ~
rq. ; -
16-1
.amongst people (about'the drug. traffic on site?
-2
'MR.
MAST:
Well,--I know what's out here; I don't 3
Particularly get-into it.
I do some -- I have,-and I don't-1 w.
jC 4
particularly care;to doLit out on the job.
5 INVESTIGATOR:
Well it's something that 'just doesn'
[t 6f have its place:here, just like boozei you know.
We don't want l7L
'PeoP e drinking here, either.
Whether it's marijuana or l
a whether it's alcohol,. it has the.same effect on a workman.
9 He's not going to be sharp, and if he's (inaudible).. Safety
.10 :
'for.himself and others, but what he's doing he can'tLdofa very
-11 ngood job if he doesn't_have control of all his faculties.
12 Gene, do you have any-other. questions?
p 13 INVESTIGATOR: No.
14 INVESTIGATOR:
Dan, we appreciate your cooperation 15 and --
16
-INVESTIGATOR:
Is there anything that you would li like to talk to us -
oh, any concerns, anything?.
18' MR. MAST:
I would like to make a statement as 19 far as, what I've seen as far as the quality of work.
I think N
most of it is exceptionally good as far'as the electrical end 21 of it, as far as mechanically sound, I think -- as a matter of 22
~ fact,.I think some pf it is just way overkill, you know.
23 INVESTIGATOR:
Well, of course you know a lot of 24 this redundancy is for safety purposes.
25 MR. f1AST :
Yes, I understand that.
But I can't say

it's not_a' good installation, from what I've seen.

I:believe that's all I need-to say.
