Exerpt of IE Interview of 45 Craig Faust f'

d, April 21. 1979 L

1l FAUST:

Well, I can't say that we - I don't think anybody really b

2,6 didn't think that we did have a problem.

We were having a problem t

3[

with - we just couldn't reason out for ourselves what would be giving g

us this problem, the way we were seeing.

It turned out that - it a

fi seemed like we could hold pressure, but we couldn't drop off too far c

l~

i in the makeup to get pressurizer level to come down any further.

It 6

was dancing high on the range, the indicating range there.

And you 7

know, that's telling you, you've got a problem.

The thing of it is',

8, s

trying to figure out what'it is, at that time, and get other things -

t e.

that about all I can say about it - and get other things done that you 10j knew you wanted to get done and get out of the way.

li 12b HUNTER:

Well, during our last interview, we made it down to a point

..a y.;

where you had, basically the generator levels were recovered and 4

things were looking fairly stable.

And then you indicated that you had moved across then to the makeup panel.

17 FAUST:

Before I went over there,

'before I got over to the makeup

FAUST:

All right.

And plus, n'ow after this, we had secured the RC -

I'm talking like, now it's like 70 minutes, 80 minutes in to

MARSH:

At this point here, I would like to break for just a minute 7

and replace tapes.

The time is now 4:28 and I'm 26 feet on the meter and I'll be ending at this time.

The time is 4:40.

The date is April g

21, 1979.

We are continuing with a second reel on the interview of o

Mr. Craig Faust.

I have zerced out the meter, and we are, once again, 10 g ing with a new tape.

People present are still Dorwin Hunter, Larry 11 Jackson,'Mr. Craig Faust, and myself, Bob Marsh.

Dorwin, I think you 12 had finished up with a question, and I'll let you pick up again at 3

this time.

1,r

.I 15l HUNTER-You were going to expound on a restart problem or an indicated 76 f

problem.

g 18 FAUST:

0. K.

Like I said, like I was saying, ind cations I was getting on'NIs 1 and 2, mainly... the thing that I was watching pretty well, was also the strip chart recorder on this was giving us trends of it, which would be NI 1 and intermediate range NI 4, which was showing up 22 there.

NI 1 started trending up.

We had stopped the RC pumps, trying 23 to establish natural circulatio'n, and it was becoming pretty obvious 24 that we weren't getting.

But, one of,the main things I was noticing 25

p, i

,i

' l1 47 I

i.

I was increases on the counts on NI 1, which would go up a little bit, 2 !

settle back down.

It would almost be like a i ouncing -- well, not 3;

bouncing, but it'd be a trend, and then back down.

I noted this to l

4L the supervisor and everybody else that was there at the time, which we 4

5 had quite a few people around then.

f 6

7 HUNTER:

Excuse me, would-the supervisor be Bill

...?

8 FAUST:

Yes, it would be Bill Zewe.

Well, there was a lot of people c'

i i

there.

There was Kuhn, Kunder was in, I think Joe Logan was there at 10 this time, I believe.

Somewhere in there, I can't be sure if it was 11, Mike Ros's was in here now or not - I think he came later.

Anyway, I started seeing the trends go up.

I pointed it out, went on monitoring 13 this, as well as just trying to watch the generators.

I was also g

i 7_o !

feeding the generators up during this, to 50% indication on the operating i

g MAP.SH:

You say you pointed it out - do you recall to whom or do you g

mean you just called it out in general?

20 FAUST:

Well, I noted it - I pointed it out to Fred Scheimann, our foreman, because he was right along.

He was watching pressurizer level and pressure at the time, trying to help control that.

I'm pretty sure Ed heard me becaust he was over a.ound the panel there.

I 24 know I got Bill Zewe, I can't remember, when we first started to get 25 V

'i k

U 1!i first indications, if I got the word to him right then, but when I t

t zg started getting a good solid increase and I actually picked up on the 3

intermediate range on it, and I was getting a little concerned about 4

getting -- I wanted to try to start an RC pump.

'I don't know what 5

their reasons where, but that alone, I felt that we weren't getting 6

water or boron in there.

Earlier -- I shouldn't even bring that in 7

now -- but I just felt we weren't getting water in there.

8 MARSH:

Feel free to bring,in anything you want to discuss, but at g

this time, was there any discussion of courses of action, or do you 10 recall aryy response to your calling this out?

11 12!

FAUST:

The discussion was being carried on, more or less.

We were g

talking about it, but the main discussion I - you know, it is hard g

for me to say -- seemed like -- it wasn't with me anyway, for the most 16l Part.

I was relaying information, more or less reacting to what I saw the best I could.

The decisions were -- I'm using the term like coming from behind me, wnich would have been Bill, and Kunder, and I-

,Sl A

believe Joe Logan at this time.

I'm really not sure of all these people right then.

But we were talking about starting it.

I said something about I just wanted to jog it just to get water in, jog the thing,. shoot water in, just move it in instead of trying to run it, because at this time everybody was pretty well assured, assured thah

/

Tit:i NM.,u r Ji we were drawing a... producing a lot of steam in the core.

Something M4 else I would like to just emphasize is,that just prior to stopping 25l L

.!n 49 r i

, Iq those pumps, we did reinitiate, we hit high pressure injection just 3

prior to stopping the pumps.

I don't know if that was brought up st 3'

before, it should be though.

We got the decision, in other words, we I ~We made the decision a.nd I'm not sure how you can look at'that./

4[

~r 5l decided, anyway I'd look at it at all of this to get one of those 6'

pumps back on.

I made the initial attempt myself to starting the 7

pumps and I started with t'he A pumps, and my reasoning there, once g_

again, was get spray back at first, if we could, so we would have spray control and pressure.

We needed it.

I worked my way across, o'l 10l and I oelieve it was, I ended up getting the two B going.

Neither of I

the'A pumps would start.

The B pump picked up and ran, but it ran g

with little or no indication of flow.

But there was enough amps to have the initial peg out on the amps, peak ou on the amps, and they 3

came back and they went to near.next to nothing, they were down around g

i 100 or something like that.

Definitely they were reading the meter f

ci sely, but it was darn low that it was wrong.

16 17 HONTER:

When you normally start a pump at the current pegs, how long g

did it take for the current to come back?

g

\\ 20 FAUST:

It's under, it's right about 9 seconds, in that range.

It came back pretty quick.

It just bounced up anti then came right back.

' 23 HUNTER:

So, and then it stayed at 100 amps.

g li FAUST.

Right, which sort of tells you...

I don't even think that 2 l registered right then, but I just remember that the amps went up and' 3

came off right away.

0.K., I can remember that now, but I at the time 4

I can't.

I can' t honestly say I said, "Oh my gosh.

Look at this."

5 6

MARSH:

I'm not a technical type, but what would that tell me, that 7

it's not catching, it's just spinning free?

?

FAUST:

What we would relate that to, would be like no impeller hooked g

10 up.

It's just spinning the motor.

11 p 1

UNTER:

Okay.

And one point you pointed out and I understand...

and we'll still talk about, I want to go back before you stopped the 73 74f pump.

You indicated that you had manually initiated ESF safety injection, l

and at that time that would put the two high pressure injection pumps s

15 16 kl7 FAUST:

Right.

19 HUNTER:

At maximum flow?

21-FAUST:

Right.

Well, at sixteens would travel open till a preset at 22 240, actual a total 250 gpm in each loop.

In other words, I'm saying it would be putting actually a 1,000 gpm.

That'ss what they're set up 24 to do, 250 per loop off the pumps.

Y

51 i

10, HUNTER:

And what was the reasoning behind initiating SI?

2[k 3

FAUST:

You're taking off your main coolant flow path, now, so our 4

trend of thought was, at least mine was, you want water going in 5

there.

You're trying to establish natural circulation, but to me we 6

were also under situatier.s that 16..' + really indicate that, to me, N7 that we were 'gonna make it because we started to cavitate our pumps.

Its a lot of -

th2 indication to me was a lot of voids, whatever you g

9 want to call it, voiding out in the loops.

So we -- I'm not sure 10 which -- it seemed like, try.

We were trying to establish circulation.

11 We had flow before we stopped it, so to us it wasn't inconceivable, l

anyway.

12 13 HUNTER:

Who initiated the ESF?

y,I o

15 W

FAUST:

Ed Fredrick.

16_S

_g HUNTER:

Okay, were you in that area then, near the pumps, or you were g

near the pumps but....

g

.20 FAUST:

I was at the RC pumps.

'Cause I was the one that - I did initial start attempts on them and started the first one.

23 HUNTER:

All right, and when thit B pump kicker' off low, starting current up, back down immediately almost, very quickly, and running 25 g

100, what was the first thing that happened thera k---

~

J

. * ). '-

52 E

e ;

1; FAUST:

The first thing I was looking at was the NI(s), they went down 2l and stayed down.

That's what I was observing, that's what I was i

3 really -- I'm sure everybody else was too -- but I was really concerned about that because I was starting to wonder exactly what I was seeing 4j s

there.

To me I assumed right off it was the indication of restart 6'

accident.

It's an indication that we don't have boron in there.

We f

were already coming, you know -- zenon should be doing everything for a

us, as far as building up and peaking out at this time, but for some g'

reason we were still getting indications on this NIs going up, which ever way it you analyze that out now, I don't know.

But I think it 10 was considerations of starting the pump were not only that helping in 11 L there, t' hey were talking about restarting them just for flow, just to try to get flow back into it because, by this time, it didn't look 73 like we were establishing natural circulation.

So,....

MARSH:

Again, you said "they" were talking about it.

Are we still yg talking about who, Zewe and who else?

p 18J FAUST:

I'm being a little, I'm being actually vague about this because e e Pu n g W in, but u h ately ne dec W on u rea Q &

e 20, something would be stated by the supervisor.

22 HUNTER:

In your case that would be...

Bill Zewe.
