l' MODERATOR:
This is an interview with Craig Faust.
0.K. (cough).
Do you i
2; guys have anything you want to cover on this?
(N0 NAMES MENTIONED) 3 4
INTERVIEWER:
Just in general.
Do you remember when you first got an 5
indication that there was activity in the reactor building and the auxiliary 6
building?
7 8
FAUST: Not...
9 INTERVIEWER:
In relation to the events that were occurring.
10 11.
FAUST:
12 0.K., it was prior to us tripping the RC pumps, the first set of RC g
13 pumps, shutting down and, uh, things like that.
I believe it was prior to 14 the initial isolation of the generator, l'm sure of that.
I think it was rigi.; around that time.
The date that... I'm really having a hard time 15 with the actual sequence of isolating the generator.
Ed and Bill helped me out when I was trying to get the time, because I was almost convinced it g
was before we isolated the generator, the B, when we restarted the A...
and tried to restart the RC pumps and we got one to bump, to jog.
Then, the 19l thing lit up, and I thought that was when I fully isolated the generator.
I was checking before we isolated it...
it had to be before, because we weren't into what we were into.
All right, I know that now.
I'm still hairy on it, but I know it had to be before it, because we were looking at things, and these were some of the problems we were looking at they were having and we were trying to question out.

INTERVIEWER:
When you ran those cociant pumps, how many of them did you 2:
run?
l 31 f
4 FAUST:
We started off with the A loop and tried to start the... came right 5
across the board and tried 1A, 2A, might have been you know, just opposite 6
of the A pumps.
We tried both loop, both A pumps, first and couldn't get 7
it to start.
We went over to the, uh, I'm trying to remember if we actually...
8 we tried to start a B pump and it wouldn't go and was sort of like the last g
throw and one pump went, picked up for us.
It didn't show much, but it was 10 en ugh to turn what we were seeing... there were two things going at the lli time we were really worried about.
We, first of all knew we definitely had 12 a problem by that tima, you know.
We thought we were... we felt we had a 13 bubble over where we don't want it, definitely.
We weren't seeing any natural circulation, temperature-wise.
The other thing that was really 13l bothering me was the trend on count rate, started, trending up at this...
we had spurious going up and down, I still believe the indication to me...
16 my first indication is somehow we're restarting...
18(
INTERVIEWER:
Right, you had a restart action...
I 20 FAUST:
...so, I myself, felt, the way we were going high pressure injection, we just weren't getting it into the core and it was boiling out.
The boron was diluting itself, and I'm not sure, it could have been the temperature heating up tco, I guess, and just staying more out.
I know I said somewhere along there, "we've got to restart one of those pumps."
TMt"h0 wha @/j, 2gno '56 l.
3 l'
you know, Bill was talking about it.
I can't say what they were seeing, 2
but I can say what I was thinking if I can remember what I was thinking, 3,
and that's one of the things I avoid, by that time, why, we've just got to 4
get it started.
(NOISE).
I don't know if I'm answering your question 5
right now, but...
6 7
INTERVIEWER:
No, that's fine...
8 FAUST:
...but we did attempt it, and it jogged enough in there that as g
10 soon as it got in there the counts went right back down.
We started having 11 other problems.
12 INTERVIEWER:
13 You were feeding the generators and having trouble controlling i
i B?
14!
~
l 151 j
FAUST:
On B generator, it turns out to have been right, 8 minutes into it approximately; just for a time right now that they're saying before we got flow into it-you've heard us before we thought we got it right away--
thought we'd discovered the problem but it was obvious we didn't from the ground.
The first generator to come up was the B; it regained level and I saw level change in it, so it kept keeping feeding and A lag behind it.
I got up to about 25 inches on the B and I just started throttling back on it because at this time I was going for low-level limits to establish low-level limits on the generator.
The A... I can't say the time in between because I was throttling off the 11s at this time--we had already reopened 25' 2000 '57 I
t I
4 1
the 12A and B--and started just regaining level in that generator through 2
that means.
3 4
INTERVIEWER:
When you start feeding in first, you reall.y...
5 61 FAUST:
I was worried about getting water in there.
I realized, you know, 7
you're trying to remember a lot of limits you're supposed to be meeting, g
but relative to sitting there I was thinking "that's the heat first like in g
the... there's no water there.
I had my doubts on it.
I can remember now 10 vaguely catching pressure coming down; that was one of the things I was 1
king for.
I thought pressure never changed, but it did initially drop 11!
12 I didn't spend time looking exactly what it was going down to, but I down.
13 saw the drop and it came back up.
It was telling me, once again relating g
to the graph, that what I was looking at at that time was, I was starting to feed then and I was just getting pressure back.
Apparently, we had to 15 (unintelligible) 16t 17, INTERVIEWER:
Were you feeding B any faster or slower than A?
1 81 19l l
FAUST:
The valves were wide open when I started.
20[
21 INTERVIEWER:
I'm trying to get some reason why you were having trouble i
with B.
B seemed to come quicker than A, and if you were feeding it, well, actually, didn't it come benind a little bit and then it overshot?
24 25l

i l
5 l'
FAUST:
I could be wrong...
2 3
INTERVIEWER:
What did the graph say...
4 5
FAUST:
Well, the graph I was looking at said "A", right?
But I'm just 6
remembering what I...
7 8
INTERVIEWER:
...the A came up first?
9 10i FAUST:
I thought the B did.
l 111 INTERVIEWER:
Oh, the B did, o.k.
g 13 FAUST:
14 If you look at the graphs it looks like it started bringing the A level up first, but maybe I just... I don't know, maybe I just scrutinized 15 it so tight that... so hard that...
17 INTERVIEWER:
Which of the 11 valves did you open first?
g 19 FAUST:
I opened them both.
0' 21, INTERVIEWER:
I mean the 12 valves.
22 23 FAUST:
Both 12s... I opened I guess the bottom one first, and that would be...
should be 12A.
The bottom one is 12A...no, that wouldn't make sense.
l 6
l pon] '59 i
6 1
I did open 12A, because I pushed the sign across--there was a tag lying, i
2j hanging over the B--I pushed that aside.
I did this while I was saying i
3l
" hey, the 12 is shut."
1 4
5 INTERVIEWER:
Yeah, I remember that from the transcript.
6 7
FAUST:
I guess I would have gotten the A first, and that would have been g
the one that travelled first.
9 10 INTERVIEWER:
What did you do for... what did you have for indication in lit the control room... (8ACKGROUND NOISE) for 12A and 8.
12, FAUST:
We have dual indication on it...
13 14 INTERVIEWER:
Open and closed?
15 i
16i FAUST:
Right.
When I'm saying dual, I'm just indicating intermediate 8,.
p sition on the 11... excuse me, let me back up a little... you're asking g'
about the 12.
20' INTERVIEWER:
Right.
22 FAUST:
We have indication of just lights on the 12.
Open and closed lights, right.
They were green.
241 1
2s!
2000 '60 t
7 11 INTERVIEWER:
- 0. K.
Are those positive... are those off the microswitches l
2!
on a (unintelligible) they're positive.
l 3!
4j FAUST:
I believe they're the, uh, they're uh, I'm trying to think of a 5
type... that it's not... I don't think it's limit switches as much as it's, 6l uh... I'd have to look at it.
7 8
INTERVIEWER:
No.
9.
FAUST:
I think it's about... I'm thinking...the dual indication on those, 10 11 right?
12i INTERVIEWER:
Right.
13 14,
}
FAUST:
I keep feeling like they're limit switches because they're...you Can hit either one you get them both.
17 INTERVIEWER:
When you come off the seat you have them both on, and when 18l gl you hit full open one goes out.
Do you have the same thing on the 11s?
20i FAUST:
Yep.
22 INTERVIEWER:
You had intermediate indication on the 11s?
23 24 2s, 2000
'61 i
l 8
1 FAUST:
Yes.
When I came back over, and here's what confuses me a little, 2.
too. I'm not sure I really saw red indication on the 11s.
What I looked at 1
3l was the Bailley controllers, initially while scanning it, and I could have 1
4l picked up another light there.
I thought I saw... the Bailleys were indi-5 cating a full demand /open.
I thought I saw c'.i indication on...
the 11s 6
were travelling at that time, which wouldn't make sense to me now.
They 7
should have been open when I came back, so when I came back over and I said 8
"we're not feeding the generators," I think Ed glanced over at that time or g
came over beside me momentarily and, uh, he noted the dual indication, too, 10, because I was en the 11s by then and I was just pushing the demands open.
3 Just reached down and grabbed them and put them into manual, pushed them open.
That's when we both noted the travelling of the valves.
At that time I didn't try to analyze it.
14
]
INTERVIEWER:
You isolated B generator...
I 16i FAUST:
...when I started going above low-level limit.
I got up to about 30, 40--between 30 and 40 inches in it--and I started backing down had to 18{
cut down.
I didn't cut it all the way off yet, right, but I travelled 19l 3
pretty heavily down on the B.
The level just kept going up.
I shut the 20 118, watched it, I still closely watch the generator level, and kept drifting up, it.
I reshut 128, it had a trend up on it, a gradual trend wiiich started giving me the feeling that maybe we were leaking into the B; we had 23 just had a tube leak somewhere or several, whatever it was, a leak to the B 24 2nn0 '62 from the primary.
25
9 l
1 INTERVIEWER:
0.K., is that when you isolated the B?
2 FAUST:
No, it wasn't right at that time.
I shut another valve down 3l 4
further just...as to say "maybe they're both leaking by" and went to three 5
valve isolation.
We started checking... this is a while into it...
this is 6
where it came about that we are still feeding it and think we might have a 7
leak in the B generator and we started looking at the pressure, too.
8 Pressure on the B, you know... we have gauges on the console for both gj generator pressures.
The B was down, and that's when I selected... you can 10 see on the graph I think several spikes on the graph... where I was shifting 11!
them back over... and you can see where the B generator pressure was.
It I
g didn't reach latch yet, but it's coming dcwn.
13 INTERVIEWER:
Do you have a feel for any timing, pf that?
14{
15:
FAUST:
16 I think you'd better rely on the graph; the graph would mark that point.
It was right after that that we isolated the B generator.
I think g
y u have it.
I was looking for that...do you have a copy of that one?
8{
19f INTERVIEWER:
Which one?
20!
i 21 FAUST:
The o.,e that shows that the steam generator, the A and B, the chart report.
24 25l 2000 163 i
10 1
INTERVIEWER:
Yeah.
I 2
3 FAUST:
Because I was curious myself as to what time it was.
4 5
INTERVIEWER:
I'll show you what we have on these.
You had the B isolated.
6 Did you take it back out of isolation at any time?
7 FAUST:
I don't believe I did, because level was still coming up on it.
I 8
g didn't really have to...the B was pretty high now already, so I didn't 10 really have to feed it up.
It was feeding itself up.
But, uh, once again g
this is a bad place for me to try to remember what I did with that B generator now.
I can't remember feeding it up.
I don't know if I just blanked it p
13 a, but I can't remember feeding it up after that.
I thought we isolated it, and that's the way it stayed.
Level just gradually drifted up 15l 16i INTERVIEWER:
You... were you controlling bypass, too?
17l 18l FAUST:
Yes.
T3y, at the time hadn't dropped any; it came down to about 5, uh, tha niitial end of it came to hang up around 550, somewhere in there.
Dropped a little, and header pressure seemed to be where it should.
Bypasses shouldn't have been opened; seems to me it was where it was supposed to be as far as header pressure.
We didn't seem to be cooling any.
I thought may be coming from a malfunctioning in it and I took the bypass 24 valve and c*acked it to get steam flow on it.
25 2nn0 '64 i
f l
11 1,
INTERVIEWER:
You....the turbine bypass valves, you cracked them?
2 3
FAUST:
Right.
I cracked those by, I thought, manually.
Those, the (NOISE),
4l I.took it out of... the Bailly controls in manual and just cracked them 5
slightly, because I didn't want to promote any excessive cooldown rate.
6 7
INTERVIEWER:
Which generator did you do that on?
Both of them?
8 g
FAUST:
At that time, that was, uh...
I did it on both of them at that I
time.
This was before we suspected a leak in the B generator.
10, 11 INTERVIEWER:
- 0. K.
And, uh, did, uh, you don't kncw what you... did you 12 13 have a feel for the time that you did that act?
14, FAUST:
15 That would have been put right around where the, uh, I took the ma n ee va es, r
e emergency feed valves... R wouM be shordy aner 16 I regained steam generator level.
That was my main concern right at that g
poli;t.
It Would have been shortly after that.
You know, if you looked on I
it, I'd say it'd probably be about... looking like it was about 20 minutes 19l 1
into it.
20 21; INTERVIEWER:
0.K....
22 FAUST:
...that time period.
24 25
12 1
INTERVIEWER:
Let's see... you...
2 f
3 FAUST:
You're not worried about, uh, other things we were doing... like we 4
were just putting... I was preparing trying to get a feed pump back on...
5 these are just... we have incidental things we were doing.
Gj 7
INTERVIEWER:
Oh?
8 gj FAUST:
Part cf the procedure is...
10f INTERVIEWER:
You finally shifted to a condensate pump you?
11 12 FAUST:
13 That was, uh, I didn't shift to a condensate pu,T.p... that was towards the... that was a couple hours...
14 I
15!
16j e
a sa rg mean, GaC s what your f
findings...
7 18l FAUST:
Yeah.
We started feeding...
19{
20 INTERVIEWER:
That was, what?
Several hours into it...
22 FAUST:
I'd say, yeah.
Because we arrived at 6:00 in the morning, pressure wasn't good... I didn't shift to a condensate pump until steam generator pressure came down on them that would allow me to feed them with it.
Up 25 until that time, why, we shut off the emergency feed pump.
And, uh...
2000 '66
13 1
INTERVIEWER:
Our whole time after the initial transient... the initial 2
transient took you up to the steam generator, power operators, well, the 3
atmospheric dump, condensor dtmp and some of the relief valves.
4l 5
FAUST:
Yeah.
6 7
INTERVIEWER:
Then you came back down, and from that point (NOISE) the g
atmospheric shut off and you were dumping steam into the main condenser, g
right?
10' FAUST:
Rignt.
11 12 INTERVIEWER:
13 And you had... you had a, uh, you had gland seal on the main g
condenser off of (NOISE)... main steam for a while...
15i FAUST:
We had that all the way through... Unit I lost its boilers.
We were off our own main stes:::-for the, uh, you know... we were off it even 18(
i 19l i
INTERVIEWER:
0.K., when did you leave?
20' 21' FAUST:
Was it 4:00 in the morninJ?
I think... it was arouno 3:30, 4:00 when I got relieved.
2000 '67 24 25 l
t
14 1
I:lTERVIEWER:
That afternoon?
l 2
3 FAUST:
Y?ah, we had just... it looked like we were going to regain pressur-4.
izer level.
We got our first...
t 5
6 INTERVIEWER:
...first lift...
7 FAUST:
... hopes of speed to getting it back.
I t was short' lived.
g 9
i INTERVIEWER:
So it was just about 3:30 or 4 in the afternoon when you did 10 at?
11 12
^
9 13 14 15l INTERVIEWER:
0.K., thtt was when you went to a condensate pump.
You were t
discharging then with a condensate pump to...
17 FAUST:
I had been feeding prior to getting relieved.
191 I
INTERVIEWER:
That was a condensate...
20 21 FAUS7:
..that was a condensate pump.
22 23 INTERVIEWER:
How long had you been...

{
15 1
FAUST:
That's what I'm trying...
place that one.
2 3
INTERVIEWER:
C. K.
4 5
FAUST:
I would guess, to say, I'm going backwards now from when I left, 6
and I'm saying it was probably about an hour and a half back when I left.
7 INTERVIEWER:
So that would be about 2:30 in the afternoon.
8l 9
FAUST:
Yeah, o.k.
I'm guessing on that one.
It's just the way it seemed.
10 11 INTERVIEWER:
- 0. K.
Anybody else have anything they want to ask?
12 13 p
After you cut the reactor coolant pumps off, there was a period of time when they weren't ru1ning without any reactor coolaiit pumps, then they 15 started a pump.
You remember whether that, when after that pump was shut 16 off, -iiether an hour later they tried to start another pury and ran it for g
a period of time?
18]
19j 20; FAUST:
I... we, uh, started... we shut the A and the 8, or the A pumps down, at about (NOISE) 9, approximately 20 minutes later, that we shut the Bs off...
there's a period of time there, that we... before we tried to restart it.
Is that what you're talking about?
24 J000 169 25 l
I t
l
f 16 1
INTERVIEWER:
You had a period...
2 3
FAUST:
... that we tried to start all the pumps...
4 5
INTERVIEWER:
Right.
6 FAUST:
We got one that went, but, uh...
everything indicated we'd better 7
g get it back off, because it wasn't dcing anything... it did something for g'
us, but it wasn't doing what we wanted it to do.
We expected flow; we didn't get it.
That's when, uh, we took it off, 10 l.L INTERVIEWER:
Hmmm.
Do you know if they tried to restart it after that?
13 FAUST:
If they did, I wasn't aware of it at that time.
I don't remember us trying to restart another RC pump at that time.
Before I left.
15 i 16 INTERVIEWER:
Craig, I guess that the first thing that's serious that happened on this thing was that a condensate pump tripped (MICROPHONE 18t l
MOVED CLOSER--SCRAPING)
The first thing that appears to have t.appened on 19{
this was the condensate pump trip.
Do you have any opinions of what might 20!
have happened there, or have you ever experienced this before, or anything 21 like that? Just your own personal opinion, don' t...
22 23 l
FAUST:
The only time I experienced a condensate pump trip was not at 241 power.
It was when we were shut down for refueling.
We were just heating 25j l
l 2000 '70 i
17 1.
on the secondary side.
I'm not sure I... you know, that was due to runaut 2
on the pumps when we were sending water back to the Unit 1.
The return 3
valve which was open too far at the time--there was a flow on the one pump.
4 5
INTERVIEWER:
(Unintelligible) a recurred trip?
6 7
FAUST:
Yeah.
Like I said, that was when we were just on feedwater heating at that time.
g 9
INTERVIEWER:
There wasn't anything going on that night that would cause 10 that to happen that you know of?
11 12 FAUST:
Not that I know cf.
It was a rather routine night.
13 14 15l:
INTERVIEWER:
All the readings you took were normal readings?
Nothing I
unusual?
16i 17
~
FAUST:
Nothing that I... I wouldn't have questioned anything, let's put it g
that way.
That night--it was that kind of routine; I can't believe how fast we've changed.
21 i
INTERVIEWER:
How about that voltage alarm' 2 28 23 FAUST:
0.K., that... like I said, I heard that, about that, during, I 24 think it was after the whole thing.
25 2000
'71 i
18 1
INTERVIEWER:
0.K., you didn't see that?
2 3l FAUST:
No, that was... they were checking into that.
That was just, it 4
was sort of like a... it was an alarm, just something that to be looking 5
into.
It wasn't something to get alarmed (ha)... get worried about.
6 INTERVIEWER:
Have you ever have those alarms come in before? When nothing 7
g happened but the alarms went off...
9 FAUST:
Yes.
10 We've had voltage alarms come in; apparently they just went in and out like they came in.
3 I
12l INTERVIEWER:
When they come in, they don't cause any equipment to draw up or anything that you know of?
f 15!
FAUST:
No.
16!
17 INTERVIEWER:
So, you know, you get the alarm and you can't see any effect 18 that would indicate why you have an alarm and no equipment seems to be malfunctioning?
20j 21 FAUST:
That's right.
22 23 INTERVIEWER:
(N0ISE)
Can you describe what you did to control the plant...
24 on the accumulators while you' re...
25 2000 '72 t
19
.I 1.
FAUST:
... like core flood.
I 2'
3 INTERVIEWER:
Cause I'm a Westinghouse ;ay...
4 5
(Laughter) 6 7l FAUST:
Well, the, oh, mainly we just, uh, knocked off the heaters and let g
the pressure drop.
9 INTERVIEWER:
About what time did you do that?
10 11 FAUST:
12 This had to be about an hour into the, uh, no, it was more that that... this was about an hour into the... somewhere within an hour after 3
the general emergency condition was declared.
I 15j INTERVIEWER:
So this was well after.the time the pumps had been stopped and started again, and you were back on one pump?
17 1Ej FAUST:
No, we weren't on one pump.
i 39l 20l INTERVIEWER:
0.K., so you had attempted to start all the pumps, by this time?
22 23 FAUST:
Right.
24 2000
'73 25i i
i
/
i
f 20 1..
INTERVIEWER:
And it was between the time you quick that and got one pump 2
running again?
I 4
FAUST:
From what I can remember...weli I...
I can't say that.
I was 5
there... I was over there, because I was on the, uh, I was working the 6
condensate pump.
When we were doing it, we were constantly plagued by, uh, 7
building pressure.
We were in spikes from uh, not spikesuh, gradual trend 8
up in the reactor building pressure to the point where it gave us an ES.
8 g
Reactor building isolation and cooling, which if your pumps start and stop in there, why, it was us regaining to where we were.
Trying to hold what 10 we had.

This was going on at that time?

Yes.

When you were trying to get down on the core...
181 FAUST:
... core flood tank.
13 20' INTERVIEWER:
How did you line up those core floods after.. did you ever along.
22 23l FAUST:
We floated them on it.
It didn't, like I said, my, what I had in 24 mind of it doing was actually trying to drop pressure far enough to have 25

them flood in, and we never obtained that.
We ended up floating on them to 2
where we just held the pressure, they held the pressure where we were at.

INTERVIEWER:
All right.
You didn't change your lineup to do that, though?

FAUST:
Makeup system?

INTERVIEWER:
Yes.
9 FAUST:
We, uh, we throttled down on makeup, but I can't remember ever 10 3
chutting if off.
We always had some makeup going... we knew how we were 12 m ving heat now, and that was through whatever we were just keeping up against the core.

What about the containment building spike... reactor con-15 tainment building soike?

I FAUST:
At the time, when I saw it at first, now and then I...later on and 18l even then, why, I figured it couldn't have been a little bit after because 19l i
all of it went up four channels and we figured we had, uh, probably had 20l t
some sort of a minor earthquake, (NOISE), because that's what it looked 21{
like.
Shock waves, from it.

No.

INTERVIEWER:
Did it affect the pumps or anything?

FAUST:
Didn't see any change in it or anything, except we had to re...
we 6
stopped the, uh... you know, pressure dropped right back off, and we reiso-7 lated... stopped the building spray pumps.
The reasoning there is, uh, I g
didn' t think... we didn' t think we needed... I'm tal king "we-,I_ didn' t gl think we needed a valve.
10 INTERVIEWER:
Right.
- 0. K.
The spray pumps came on automatically?
11l 12 FAUST:
Right.
13 14 INTERVIEWER:
15 And then you knocked them off before they started spraying, r did they actually begin spraying?
16 17 FAUST:
I don ' t kriow... I would have to say Ed could tell you what kind
,8; 19l of... maybe tell you what kind of discharge pressures were on the pumps, 40l he's the one that was at that point standing there.

I don't know how long he had them on before he... before they were 24 turned off or...

Did you start any... was there any equipment other than i
2t valves starting at this point?

Uh...

INTERVIEWER:
Like an internal circulation system?
7 FAUST:
We started, back earlier when we first noted building pressure, we 8
g put on emergency... reactor building emerge-cy cooling.
This started two 10, pumps.
Later on, I found one of the pumps that was in the... you have to g
go to test on it to get it to run, you'r not in the auto... and it was in the test position that the pump wasn't running, so I took the backup pump and started it, turned it off.
That's about all I did on that.

INTERVIEWER:
On these condensate pumps, I have one question.
Is there a 16l standby position on that switch, the control switch, for...?
l 17 FAUST:
There is a standby position on it, but it's related to, uh, two pumps-a booster and a condensate pump-picking up togeher; if you lose a 191 string you'd pick up the other one.
That switch is normally in manual, and i
in the seated position; in other words, the operator has to do it.
I'm trying to remember the reason now that we did that..
we just operate that way and we always have been.

We had two condensate pumps online, with two boosters and two l

Two boosters?

Right.
That is during the...or prior to...
