MARSH:
I have a couple of questions at t;.e end which I would like you 7
to respond to.
Question 1 is listed as: Did you understand what was 8
in the letter?
j 9
FAUST:
Yes.
10 11 MARSH:
Do we have your permission to tape the interview?
g l
l t
l 13 FAUST:
Yes.
14 1
15 MARSH:
And, would you like a copy of the tape or transcript?
16 17 FAUST:
Yes, I would like that.
19 MARSH:
Fine, that will be provided to you.
And the 4th question, which wasn't typed on the end of the letter there but is covered in the body of the letter, is that as it indicated you can have someone from the company present or from your union.
Do you have a -
24 FAUST:
I have no preference to that, right now.

5 1l MARSH:
Okay, so are you telling me you do not want someone present?
l 2
3 FAUST:
Not unless they want to be present.
4 5
MARSH:
Okay.
6 ;
7 FAUST:
I'm saying it doesn't really matter to me.
8 g
MARSH:
Okay, more than them wanted to be present, it would have to be 1
10 that you want them here.- They obviously have a very strong feeling to l
g be here, but it is up to you to make a decision.
12 FAUST:
g I didn't talk about it with anybody, so right now I say no.
14
\\
MARSH:
0.K., fine.
All right, at that point then I am going to ask 15, Larry Jackson and Dorvin Hunter to proceed.
And I would 1.ike, for the 6
ease of transcription, that each time you do make a statement to g
proceed it with just your last name 'and it will make it easier on the 18 transcription.
19 20 HUNTER:
Okay Craig, how about go through your background again for me, and your experience and how long you have been with the company 7
and have been an operator.
24
' FAUST:
My background is from the Navy.
I served as a Machinist Mate 25 aboard the George Washington Carver.
I spent two years of pre-schooling' O
s.
j 6
t i
y prior going to the boat, and reported aboard and was aboard the George l
Washington Carver for about five years, and.after that working, like I 2
said, in the capacity of Machinist Mate, Nuclear type.
From there I 3
i 4
was hired by Met Ed and spent the next 51/2, years up to now working 5
as a A operator first, then training programs, and then the CRO.
I 6
guess it's been two years now on Unit 2.
I had previously at one time 7
went up for a CR0 in Unit 1 and more or less for just disagreements that occurred at that time just between, well who I was training 8
under, who I was training, the shift I was on, I dropped back and was g
an A0 for awhile and then I bid up again for Unit 2 when the opening 10 n
came up.
12 HUNTER:
Okay and you indicated that.you are an A operator on Unit 1 g
14 "i
FAUST-Yes, definitely an A operator on Unit 1, but we were used on 16 Unit 2 at times when needed, whenever we -- like we did the initial g
systems, the descriptions and lecture plans on.
I was involved in some of that, and just plain tracing out the plant for initial startup.
g 20 HUNTER:
And then you bid, you said, CR0 for Unit 1 and due to I
22 FAUST:
It was more or less just a disagreement between me and my 23 shift supervisor at the, time,'that I just felt I didn't want to pursue the program right at that point.
I ' dropped ba:.:k and I just bid up later on for Unit 2.
i I
i l
1 I
g.
11 7
HUNTER:
Okay, and when did you get your' license on Unit 2, do you 1[
2 f recall?
i f
3 4
FAUST:
It was March of... I'll tell you when it was.
Let me dig it 5 !
out of here.
6 7
MARSH:
Craig, what is it you are checking?
Do you have a...
8 FAUST:
I have a copy of my license... somewhere.
This is something g
I imagine you can look up' too, just as easily.
I thought I had one in 10 my wallet.
I used to carry one.
Apparently, I don't.
g 12 HUNTER:
Okay, is that '78 or '77?
g 14 FAUST:
It would be in '78.
g 16 HUNTER:
Okay.
g 1
18 g
FAUST:
Early '78 is when I got the license.
20 HUNTER: All right.
And as soon as you're licensed at the plant, then 21 you are a CR0 in training, or a A CRO?
23 FAUST:
Well actually, we're a CR0 in training up until the time we are licensed.
In other words, we worked on the panel but at this time 25 6
I I
e)
~
'i i1
~
I 8
we did not have fuel in the reactor.
It wasn't refueled so we could 1l 2!
stand watches without being licensed 6at the time, and we were in our 3
Program - our training program - at this time.
4 5
HUNTER:
Then, did you losd fuel in Unit - you were a CR0 when they loadedfuelindnit2?
6 7
8 FAUST:
Yes.
When we received our license prior to loading fuel.
9 10 HUNTER:
All right.
I didn't want to pursue the bidding for the job in Unit 1.
But just one issue, 0.K.
And I wanted to ask if it was a n
personality conflict, or what was, you know, was the - if you would n
care to comment?
3 14 FAUST:
It was a_ personality conflict more than anything.
'Cause I 3
didn't -- the forman there, the supervisor that I was dealing with, we 16 just didn't hit it off too well.
You just run up against people that p
you don't get along with and that's about all it amounted to.
g 19 HUNTER:
Does that person still work with Met Ed?
21 FAUST:
Oh yeah.
23 HUNTER:
He -- is he still a Unit 1 supervisor or...
25 O
{
9 lj FAUST:
Well, he covers both units.
I've worked under him but there i
2 l is - it's a little different, I guess, when you're training and when l
3 ;
you're licensed and working for somebody because - I don't know how i
l 4
you want to put it - it sort of a reminds me of the Navy career.
S j There were just some people I didn't want to go to for qualification 6 ;
because I just thought they were wrong -
7 8
HUNTER:
Yeah.
9 10 FAUST:
About the way they went about training.
11 HUNTER:
Is there any problem there now?
y 13 i AUST:
No, 14 t
15l i
l HUNTER:
After you got your license, was there any problem?
6 17 FAUST:
No, there wasn't.
As soon as I dropped back, there wasn't any g
problem.
g4 20 Cold l
HUNTER:
What about when you came back and bid for go'-license in Unit 21,
)
2 or CR0 in 2?
'23 i
FAUST:
There wasn't any problem with that.

1h HUNTER:
- 0. K.
The night of the 28th, or the night of the 27th, you 2
came on the 11:00-7:00 and as I understand nd recall in our previous 3
tapes, you were the CR0 taking readings in the t.ontrol Room.
4
~
5 FAUST:
Yes.
6 7
HutRER:
And Ed Frederick was the panel CR0 that night.
- 0. K.
And go 8
through again what your duties are, in that position, as a CRO.
9 FAUST:
As a - well we call it switching and tagging CRO.
We take 10 care of writing up safety tags, when there are safety tags to write n
up, whenever an application form is put in for it.
On the back-shift 3
like this, and also when you are operating, you don't normally have 13 too many tags to write up because there is not a great deal of maintenance 14 g ing n.
And once this night, I didn't even have any to write up, so 15 all I was doing, for the most part,.was our normal data acquisition, 16f where you just go around and get a set of certain readings you take every hour or just once a shift, varying also shift surveillances',
18 which amount to when their computer schedules bring them up, provided g
there is no other cover sheet for it and you just schedule to do it O
that night.
And I was - I didn't have any of them, but I had the regular shif+. and dailys, which are called " Shift and Daily" readings, 22 to take that I was working on at that time or that I was finishing up.
24 HUNTER:
- 0. K.
And where were you located? What was your position 25 I
when you saw the Unit trip? What led you to not a the Un'it trip?
t 1
I j
11 i
lj rAUST:
I just faced the panel from where the switching and tagging i
2 desk is.
I had been walking over and turning around facing the panel 3
when the alarms came in that I first noticed on the trip, which were 4
located on the ICS alarm panel and also on the electrical board.
And 5
like I said, not before now, I'm almost sure, I had to have seen 6
alarms on the - when I say "I had to" - it was more natural for me to 7
actually be facing the one panel that I'm thinking about, which is the 8
one that's' on the secondary plant, which is, Panel 17.
The alarms had g
come on at thati spot are very -- when you're looKing at the panel 10 that's what you'd see out of the corner of your eye first.
So I'm n,
actually saying now that one of the first alarms I saw was the ICS, which was about 4 or 5 alarms on there initially.
And the ones on the g
turbine plant panel, which was probably a generator tripping - generator g
l trip panel, maybe even a condensate pump.
3 15 HUNTER:
Have you been through trips before?
16 17 18 19 HUNTER:
How many have you been through?
20 l' 21 FAUST:
I guess I've seen -- I've been in three trips before and I've i
... I don't know whether you count run-backs, too.
I've been in a 23 l couple of run backs.
I guess about 6.
l 25 i i
k i
E i
l 12 1
MARSH:
Craig, have any of those trips been here? Can you give me an 2
idea of how many trips have been here?
i l
4 FAUST:
All of the trips that I have associated with have been here.
Now, if you're talking abbut my Navy experience, I've been on aboard 5.
6 the boat, but I'wasn't in the Control Room.
My job was as a - was 7
khownasSCR,ControlRoomsupervisor.
8 g
MARSH:
The trips out here were all referring to Unit 2?
10 FAUST:
Yes.
I was going to go on to say that I have seen trips in
.n g
Unit 1, where I've been in the room, but I was only under trainee and 3
therefore, I did not get involved directly into it.
But I stood more or less, out of the operator's way so that. hey could perform what 14 they needed to do.
3 16 HUNTER: The two run-back - what were they associated with?
17 IS FAUST:
The two that I'm thinking about, were just where we had lost yg the feed pump.
And it turned out, later on we found out that it was due the FW 16 ' valves -- I got the right designation there,16.
I think.it was the B pump that we lost,16B that spiked open on us.
It went open just enough and shut, and we didn't see the valve travel, but it was enough to drop suction pressure on the pump, so we'had to 24
- drop the pump off.
And I guess we ran about 97% power and we had to 25 run back to 50% about.
We had that twice.

HUNTER:
Same problem, again?
2 3
FAUST:
But that was within the same shift, that one.
4 5
HUNTER:
- 0. K.
6 j
FAUST:
We've had other run backs.
I'm trying to place them.
There has been run backs when I've been in the Control Room, but not CR0 and 8
not even switching and tagging, but I was on, like, surveillance.
g During the day, we had extra CR0's on and they usually run the surveil-10 lance procedures that we need to go through.
n 12 i HUNTER:
What about the trips?
g 24 FAUST:
Well, one of the bigest ones we had was a trip during initial 15 startup where we were testing the steam safeties.
And we had to trip g
at approximately... it was right around 22% power.
And the bad thing gy about that was that we had a relief valve.
One of the main safeties, steam safeties, stick open on us.
It didn't re-seat.
g
'20 HUNTER:
Excuse me.
Safety on the secondary system or the primary?
22 FAUST:
It was on the secondary.
24 HUNTER:
The secondary.
- 0. K.
And it stuck open and then what happened?
25
~
I LI -
1 I
14 1
l '
FAUST:
It was more than one.
I think it was three all together.
2 They stuck at some point, where they didn't' full! re-seat when they 3
were supposed to at about - they should have re-seated like around 900 Udu) 4 pounds.
And they brought us down to a 600 pounds range or more,.which 5
gives you a pretty nasty cool down rate.
And I think it's pretty much 6
record, where you can read about it.
It shrank the pressurizer, we 7
lost the level out of the pressurizer, picked up high pressure injection g
but regained pressurizer level right away.
It was a rather sharp g
spike, where it went straight down.
In fact, I didn't even see the 10 pen drop, it went so fast.
And I carried out the procedures, once n
again.
And we managed the recovery fairly fast.
12 HUNTER:
- 0. K.
Another trip?
3 14 FAUST:
- 0. K.
There are two si.gnificant ones that are hitting me right 3
n w.
The other one's hard for me to picture when it was, but I know 16
{
we had it though.
I don't think I can picture or present it to you p
right now.
I'd have to look it up myself.
18 19 HUNTER:
- 0. K.
We'll look at it in Trailer soon.
We'll pick it up, 20 i 1
i too.
And if we have any further questions, I'll come back and we'll.
21 1 talk about it, if it's significant.
- 0. K.
And when the unit in tripped and you saw the alarms, then you, if I recall properly, you went to the makeup panel first?,
25 FAUST:
Yes.
l l
i
1 1
}
15 1
6 1 !
HUNTER:
- 0. K.
And what did you do at the makeup panel?
i 2 l I
3 FAUST:
I shut it down, shut our letdown isolation valve - MUV 376 -
4 and attempted to start the makeup pump.
First try, I know I didn't 5
hold the switch long enough.
Like I said before, it's a one second i
6 time delay for the lube oil pump on it... and to pickup and apparently 7
let the switch go too fast.
I was back on it, and just about, just as 8
I sort of let the switch go, I was back on it again, and held it over 9
on again.
The pump indicated it picked up, in other words, I got the 10 red -(stuttering), which would be really an 'ndication that the breaker closed.
Started, I even got amps on it.
When I backed off and I let n
go of the switch, the light went off but the pump tripped back off.
3, It was at that time that Ed Fredrick, whatever his movements were on 3
it, reached over and started it and I just kept going across the panel 14 4
to the feed station.
3 16 j
HUNTER:
- 0. K.
Looking at the makeup station, when you got there, what.
p was the normal charge ng in lineup, the normal makeup lineup at the g
time?
g 20 i
FAUST:
- 0. K.
"1B" makeup pump was running at this time and it was 21 just supplying normal makeup to the system, as needed, through the 17 valve - MUV 17 - and also seal injections through the RC reactor cooling pumps.
25 W
s
~
t 3
16 i
l' HUNTER:
What does that normally run - those two numbers, those two 2:
values?
3 4
FAUST:
Seal injections are usually about 40 gpra total, and it's hard 5
to tell what 17's because it varies.
At this time it was -- I can't 6
even guess
'ca'use the valve feeds, you know, automatically.
So you 7
don't really know which position it's making up.
8 g
HUNTER:
What about the letdown that you isolate? What was the letdown 10 lineup at that time?
11 FAUST:
0.K., that would of been around, I'd say probably about total y
3; of 50, 50 GPM, probably.
14 HUNTER:
Is that like one orifice?
or, 3
16 FAUST:
Well, it's a very -- it's an orifice.
g ISL y
HUNTER:
Okay.
20 FAUST:
I guess there around 40 while we're making up that (phoenetic).
All right, let's try to remember -- I'm getting them backwards here a minute.
24 l
HUNTER:
0.K. would I find that recorded anywhere, the makeup flow and 25 i the letdown flow?
b.
i e4 i.
1 17 l
1l FAUST:
You'll find the... no.
4 2 i 3
HUNTER:
0.K., would you have trended that on your analog recorders on j
4 the computer?
j 5,
6 FAUST:
Not unless we had a reason, and at the time we didn't.
7 8
HUNTER:
- 0. K.
What about makeup tank level?
9 FAUST:
Well, you see that is trended on the -- there is a chart 10 3
recorder for that.
12 HUNTER:
0.K., and when you shut the letdown valve there, the letdown 3
g es to, obviously goes to zero, and then you start the A, in this 14 case you started the A pump.
The sunction for the A pump is from 3
where?
16 17 FAUST:
Initially at this point, it's from the makeup tank.
19 m
20 HUNTER:
Would the pump just come on, on recire?
21,
FAUST:
The pump would come on on recire.
Actually, it would be --
the header for the A pump is lined up the same as the B pump.
That's why this one was selected initially.
25 t

d
f l
18 l
HUNTER:
- 0. K.
2 3
FAUST:
To start the "C", I would have had to go around the panel, run 3'V c
4 around that back panel E,nd open up-CHP 5A, or B rather, to get suction 5
to the C pump before I cou'ld start it, 'cause the pumps will burn up 6
in about 3 seconds without any kind of suction flow going to them.
7 8
HUNTER:
Elaborate on that a little bit for me, all right? The B pump 9
is lined up to the makeup tank.
It's normally charging flow and-letdown so it's stabilized and balanced.
10 11 FAUST:
Right.
y 13 HUNTER:
And you start the A pump, and its suction is from where?
14 l
FAUST:
It's. coming off the same flow pack that the B pump is, the 15 makeup pump, and its discharge path will then be the same too, through 17 g ;
seal injection and reCirC.
19 E"
^
- E 20 1
21 j level would have dropped, or going down.
f 22 FAUST:
The procedures call, on a reactor trip like that, it doesn't hurt to start the A pump in this manner.
Because unless you open the 16A, you're not feeding anything else.
You can have the pump if you j
I r

li need it.
That's the big point getting it on.
Next step, is you monitor, you see what the pressurizer is doing and where your level's 2
1 I
13 going.
That's when you'd crack open your 16A valve.
And if you 4
really have a problem and are n'ot recovering it right away, the operator tyv L..>
5 would go behind and open the 16, or-CHV SA, CHV 5A, and that would put 6
you on on the EWST.
7 HUNTER:
And through the 16A valve, or whatever the--
Now what's the 8
g lineup of C?
e 10 n!
FAUST:
C is isolated from A, at this time - or this configuration at 1

Give the items that you checked as you go to the secondary 5

panel.
7 8
FAUST:
The things I was looking for first were the -- and I missed it 9
in the first part of it, but I said I saw the rod bottom lights when I 10 was heading over, at least I feel I did.
And all green lights caused, W.:hd the (unintelligible) onto that.
To me that's rod bottom lights, vefy.
g!
q That's telling me the reactor has tripped.
No question to me.
The 3
next thing I was looking for was feed station, coming from the makeup I
14 station, was to check that for going over low level limits and first thing I looked at was the startup~ range.,And I had indications that 3
f it was c ming down.
It was somewhere in mid-scale on the startup 16 p
range at this time, right.
It didn't take any time to look to see, all I wanted to see was the turn in trend down, that it was coming 8
down.
I looked over... all I can say is that I looked over and I saw 9
feed pumps were off, I don't know why I did.
I just looked over and 20 the feed pumps were off.
The next thing I checked was all the emergency i
21 ;i feed pumps on, which they were.
So I proceeded, and I figured, in my own mind, I_ figured, well, coming down to the low level limits.
And I proceeded over to the turbine plant, secondary panel...
I'm missing
'something.... Something else that_was strange to me at that time.
It
u.
l 22 1 }
wasn't strange to me but it sort of is now, because the li valves were 2
traveling open.
And to me it shouldn't.
And when I think about it i
3 now, they shouldn't have been traveling open at that time because 1 4
was still high in the operating range.
I don't think there is anything, l
you know -- as levels dropping down it has to actually has to go below 5 l low level limits a little bit before the valves start fully traveling.
6 7
Or be right within th'e range of it.
So, that could just be something I don't know.
Maybe it does travel sooner, but I think it's a device 8
that you're actually below the low level limits and then it starts 9
10 feeding -
11 HUNTER:
You were coming to the startup limits - is that what you y
a said?
13 14 FAUST:
Well, I was on mid range of the scale, which is about 150 g
inches in the startup range.
16 17 HUNTER:
- 0. K.
l 18 }
19 FAUST:
So.
We were actually down to about 30 inches, before the 0
valve should have actually opened.
It didn't hit me at the time.
I just ncticed that I was getting a dual indication on the 11 valves -
the emergency feed valves.
I'll pick it up later on then, on that.
I went over to the secondary plant, the turbine plant, and one of tiie first things I looked at' was the turbine generator, main generator O
s
l if startup and... looked at the governor valves and trottle valves 2{
indicators, to make sure that they were shut.
One was hanging up, so i
3 one thing I did do was hit the turbine trip button, to see if for some 4
reason this was the quick reaction, to see if something would - it 5,
would release it.
The indication at that time was still open on the 6
one throttle valve. 'I don't remember. I'd have to look at the panel 7
right now to tell you which one it was.
Anyway, it didn't drop down, 8
so I continued on to the... I believe I went from there to the generator j
g breakers, put them in pull-to-lock and the field breakers in pull-to-1 ck.
And I was looking on the back panel, coming back now from here, 10 11 1 oking over the back panel at the extraction valve.
The indicators back there, there's a whole list of them, and they were traveling.
So I looked at that, and also saw that saw the turbine drain valves were g
14l g ing pen, I was getting dual indication on them.
I came back across 1
l and had sort of paused.
I was going to do another part of our EP,
. a which is starting our lube oil pumps on the. ain urbine.
Then it was just like -- it was a pause.
I can get that later.
I don't have to p
worry about that now.
I went back to the feed station.
First thing 1 saw was 10 inches indication on both generators, which is, again, to g
me is a dry generator because it's also stated to treat them as if they are dry when you get below about 10 inches.
The first thing that 21
- f. u. 4 g~
i I more or less looked at was the 11 valves, and they were shot.
I 22 jumped on them, and when I say " jumped", in other words, I took the 23
..daily station for the 11 valves in hand, to manual and then drove open
~:
on them on their demands.
That time I got indication of traveling 25 t
24 valves.
And once again, it seemed faster, but I waited.
I must have 1
2 been waiting for a couple of minutes because the next thing I'm looking 3
for is to verify flow into the generator, which we do by looking at 4
level.
I realize somewhere in there that we weren't getting flow yet 5
and announced it again, I had announced the first time that the generators 6
are dry, and then I announced we still aren't feeding the generators.
7 That's when I looked down over the panel, and I'm sure I looked twice.
8 The first time I didn't see anything abnormal, but I realized that after a second scan the one indicator light for the one valve is right g
10 on the edge of the panel, and I was actually pretty well leaning over 11 the panel looking back under me like.
And I was looking for this.
12 MARSH:
Craig, can I ask you to break for just a second.
Let me 13 interrupt and change tapes here.
I'm breaking at this time.
The time 14 15 1 is 3:59 and I'm reading 472 on the meter.
It's still 3:59.
We'll continue.
16 17 FAUST:
I was making the second scan on the channel below me, when I e
18 i
saw that, it would have been the EFB 12A, indicating light was indicating g
shut.
I voiced, I starting voicing, I voiced actually both of to them g
shut.
I know I yelled that out.
And I was reaching for the 12, and there was this tag that we had on the. EFV 16 it's FWV 16B, which had problems with it due to -- it's an automatic recirc valve for the feed pump.
The tag from that was covering the uppper valve lights, indicating lights.
It was like - I can't remember the motions, but I pushed the P
h
[
i 25 1
tag aside and at the same time just about was opening both valves, and 2'
somewhere in there at the same time saying to everybody else that I 3
knew what was going and what I found that EFV 12A and B were shut.
4 Bill Zewe the supervisor, vo' iced his opinion of it, you know, suprised 5
at it more than anything.
He said get them open.
As soon as those 6
valves started traveling -- I'm,not sure how much further along it was 7
when I found a new indication of feeding, and that was sound of the 8
noise monitor.
We were just imagining 50 to 60 degree water going g
into a hot -- down an ice cold pipe into a hot generator.
And we were 10'1 hearing it on the gen-- I'm pretty sure it'was selected to the number J
11, 5 point, which was the A generator, tube sheet for the A generator.
I fed -
12 13 14{
MARSH:
May I ask a question, before we get away from it?
Those two switches.
You talked about the tag hanging down, covering the lights 15 f the upper valve indicator lights.
16 17 1g FAUST:

I yelled - when I yelled to the operator, you mean...
g 10 MARSH:
That's the one you are addressing, is the' lower one?
11 12 FAUST:
That was the A valve, 16A... or I'm mixing them -- the 12A.
13' I'm giving 16s and As here.
That's EFV 12A was the first one I saw at 3
the time, that I yelled.
I actually yelled.
I think I put'the tag on 15 the upper one while I was going to the A valve and opening that one.
16 Flipped that, and I was reaching down and opening the B, 'cause it 7
g makes more sense to me now, and then saying 16's, or I mean the 12's are shut.
19 1
20 MARSH:
So, if I understand it right, when you initially noticed the' lower indicator lights as being closed and as you went to open that valve and flipped tag across and noticed that the upper one was also closed.

that one out to me.

feeding.
And of course, he took an immediate concern in that.
And I'm sure I wasn't alone over in that corner, though.
I just didn't look around to see who was there.
22 23 MARSH:
Do you recall-him saying anything in response to that?
Do you have any recollection at all?

action.
There wasn't any need to say anything.
For one thing, he 3
could see what I was doing.

MARSH:
Well, what you're saying is he would have been concerned.
Do 6
you recall then anything specif,ically that he did to show concern?
7 Did he start talking to you as he walked forward towards you, or do I
8 you have any recollections at all?
9 10 FAUST:
I can't remember, now, to tell you'the truth...
I think 11 somebody could be talking to me right at that point and I was so busy 121 trying to get feedback in my own mind, that I wouldn't have heard him.
13 And I imagine that's what it would have been.
He could have been 14' saying something to me and it didn't register on me.
15 HUNTER:
- 0. K.
The fact that the 11 valves were not opening when you 16 came back, or had not opened, and you were 10 inches, that shows, that p
yg appears to show a problem.
19 20 21 HUNTER _: Those valves should have fully stroked open.
23, FAUST:
Yes, they should have.

They weren't 2;
in automatic? There was nothing, you didn't do it?

The 11 valves are automatic.
5 6
HUNTER:
Right.
There was nothing wrong with them, that you are aware 7
of?
8 g
FAUST:
No.
As far as I know, we had no problems with them.
But a ---
10 11 HUNTER:
What about steam generator level at that time, steam generator 12 j I'V*I?
13 14 FAUST:
Steam generator level was at -- when I first came back over, 15 it was at 10 inches indication on both generators.
When I say 10 16 inches, you could look at the gauge on this end of it, and it's really 7
hard to read it.
It wasn't pegged out on the bottom.
And I'm pretty 18 sure that I got the 10 inches about right, because I was looking g
pretty hard at this.
But like I say, once again -- in fact, I'm not g
I even sure if it's in the procedure right now.
But we, in the past, when we had problems with the generator, it was put out that if you go below 10 inches, you assume the generator's dry.
So, that's where I was going from that point.
Somebody was behind me when I jumped on the lis.
That's about all I can say on that.
So, if it was Bill, I
25:
31 q'
1.!
that would be a good reason why he didn't say anything.
Another thing 2
that you might be thinking about is,.when I'm on the ll's there, I'm 3
actually leaning over the panel and over these 12 valves, so that he 4
couldn't see them.
5 6
HUNTER:
There is no way you could hit them... in other words, that 7
ought to have been (mumble) at that time.
8 g
FAUST:
As we were saying, I can't picture my body rubbing up against l
)
10 the switch - that type of switch.
11' HUNTER:
It's not a handle switch or a 12 13 FAUST:
You would have to be at a 30 degr'ee angle there or,less.
g l
15 HUNTER:
- 0. K.
g 17 FAUST:
And plus, one switch is even that much further up on the panel 18 than the other one, and you'd just really have a hard time hitting g
them.
21 HUNTER:
- 0. K.
I guess the question is, what channels feed -- the level channels feed those 11 valves.
And then the question would be, was the actual level that the control system supply with valves indicating i
high, and closing the valves back?
I don't know.
l!
i I
32 In FAUST:
That would have been - that comes off our startup range indication.
2 3
HUNTER:
You were looking at startup range and it was 10 inches.
I 4
5 FAUST:
That then feeds into our ICS system wher.e - that's logic, 6
whatever the logic is --
7 HUNTER:
How did you open the 11 valves? What did you do to open them g
then?
g 10' 11 FAUST:
What you do is you have to take the daily stations to manual, which are two - it's sort of like a - it's not a toggle switch, it's 12!
like a slide switch.
You just pull it down, in other words, what you 13 g
ended up doing...
Not down - I'm sorry.
What you're doing is, you're n
pushing buttons on this.
I'm thinking about the - just buttons, on 15 that part of it.
And you just hit the right side of it.
You push or lo.
press on them and it transfers the station ir.+.o a manual state where g
you c:an control it.
Then a toggle switch is onto control it.
g) 19 HUOTER:
Did you ever see those valves fail to open before?
21 FAUST:
We had problems with those valves during one of these trips that we had.
That it was the result of getting indicating lights up on the panel, so that we could tell that the 11 valves were actually
(
moving.
Because the only indication they had of it was on the daily f'
k
1 33 6
1 station itself, which is just an indication of the signal going to it.
2 Which really doesn't tell you anything.
So we had a problem with l
I 3
feeding the generators, one time before.
And it stemmed - you wastad a lot of time trying to tell' if the valve was moving by the daily 4
5 station or change in generator level, you had to wait.
There wasn't 6
any real, immediate indication.that the valve was moving.
So that what your lights came in for.
7 8
l HUNTER:
0.K. So now, after you've started feeding the generators, you i
g heard the A generator, apparently the feed' water, the crackling and 10 ',
g the hammer, noise, because of the water.
And then you were feeding to recover A water level, or what was your --.
l 13 f
FAUST:
I was shooting for a water level - 30 inches-in the generator.

15 HUNTER:

I can't remember which one it was now.
18 It's getting too far away.

HUNTER:
It's all right.
Go ahead.
21 22 FAUST:
I think I said, I believe the B level, I caess was leading.
23 One of them was leading the other one, and when I started to get an 24 indication on it, I started backing off on the 11 valve.
On the 7
e
+
II
~
1 j
34 i
1 generator an indication was coming up, because I know at the time I 2
was already feeding pretty heavily on it, but I also felt that -- I 3
didn't really have a feel, myself, to tell you how long we could go 4
without feed on those generators.
I figured, the primary was getting 5
pretty hot and I just wanted to get water in.here and start cooling 6
it down, to get some heat out of there.
I'm not sure how much of this 7
reasoning was in my mind at the time.
My main concern was that I didn't have water in the generator.
And I wanted some in there.
8 9
HUNTER:
- 0. K.
There was a point in this event also that you shifted 10 the steam dumps to manual.
12 FAUST:
This - when I was waiting - when I initially - when I first 3
hit the 11 valve, one of the things I was looking at and expecting to see for a dry generator was a fairly sharp decrease in steam pressure.
I wasn't sure at the time, while I was waiting in there, I thought maybe I am feeding it and I'm just not seeing it.
I reasoned something out to myself that I looked over, I realized that the header pressure was less than what the atmospherics was supposed to lift at.
- 0. K.
Not the atmospherics, but what the bypass valves were supposed to lift at.
They're set to go at 1010 and maintain air pressure at that.
And it was right around 1000, it was just about on the borderline, I'd say, at the time.
I figured I'd get a little cooling rate on it that 23 way, and I put the valves manual over there and cracked them.
When I 24 say cracked'them, I just hit the toggle switches until I just got the f
25 1
J 35 5
1 first indication that the light went from red to green and stopped it 2i there.
I got a drop in pressure from that, which like I say now, I 3
know I was actually just bleeding the pressure off that was in there 4
from the dry generator.
I recovered it, and it only went down about 5
300 pounds, I guess.
And I recovered it when I first starting getting i
6 steam in tere, feed in'there.
I h
HUNTER:
- 0. K.
There was a point also then that you, if I recall g
g right, that you went from the - you were having trouble and you went 10!
from the bypass valves later, to the atmospheric dumps.
l 11!
FAUST:
That was actually, I had already re-established levels, and l
3 13(
this was probably 20 minutes into it, I guess.
Because our next concern then was the secondary plant.
We wanted to try and re-p.
establish normal feed.
In fact, I think it was sooner than that.
I got involved and I directed Dale laudermilch it turned out to be, to go down and get on the reject valve, which at this time our COV 59 valves are automatic ones, and what we were worried about is if that thing, -- if we lost let the valve go wide open, it would cake away suction from the feed pump and cause a trip on us.
So what we ended 40 up doing was. throttling the downstream discharge valve on COV.60, so that when it did open there would be a more controlled reject out to the storage tanks, which for the most part, under normal operating conditions, there's no real problem with that.
Just a slower rate that you're rejecting at.
We had a hot well level --
In fact, I saw
~,
25 e
36 l
1 the tail end of go on high on the indicator up there.
And I was 2.
worried about flooding out the condensor.
I sent him down there to 3
open up the reject valve.
And we were also getting involved with 4
getting the bypass around the polishers open, which is COV 12.
That's 5
on the back panel.
We tried to open that up from the in Control Room 6
there, and Bill Zewe went around the panel to get it, so I could stay in the front there.
He pushed it and tried to get the thing to open 7
8 and it wouldn't electrically open.
So, we had an operator... and I think at that time - this has got to be a little bit after the initial g
10:
reject, getting the reject going up, or right during it.
We had, I 11' think Don Miller also went down with Bill Zewe and tried to open COV 12, of which (Name?), I think he can tell.you.
I just heard words, 12 something about the hand wheel wasn't on it.
So that was another 13 problem.
It was laying over in the corner, or something like that.
g They got it on anyway, and they got the valve cracked open to where it 15 i
c uld pen it then.
It was frozen on its seat apparently.
16 17 HUNTER:
Se once you cracked it, then the motor was running on
...?
19 FAUST:
Right.
By the time I got over to the secondary plant there, a
20 too, !omething you might want to realize is, I at this time hadn't l
realized we lost not only just the feed pumps but everything over
-there.
23 24 HUNTER:
Right.
t 25 l[

[
1 FAUST:
The only thing that was running were the heater drain pumps, 2
which were recircing the tank at low level.
In fact, I think it was 3
getting to the point where I think they should have tripped.
But by 4
the time I got over to the secondary panel there, Bill had already 5
attempted to start the condensate pumps, apparently.
And he got one 6
running, COV-2B, or -1B was running when I got over there.
It was 7
running on recirc back to the hot well.
We still had a high hot well 8
level.
I had one - I had Dale Althouse going down to open the reject 9
valve, isolation valve downstream with it, so that we could get rid of the water faster.
Another thing I attempted to do at this point was 10 11 go ver on the atmospherics; in theory just to stop dumping steam back there, to try to minimize the amount of water we were putting into the 12 hot well.
So I figured we could go onto the atmospherics for a period 13 f time, till we got control of our hot well back.
We did this by 14, 15' taking off circ water pumps, which if we down below the three circ water pumps, it automatically shifts control over to our normal daily 16 stations that are controlling the turbine bypass valves.
Then you can p
c ntrol your atmospheric dumps then.
It wasn't what I did at that 18 point.
It wasn't too long after this that we got the - I'm having a g
hard time placing one thing.
We received an outside call, and it couldn't have been at this time because we didn't have any problems that we would have somebody telling us to shu; those valves --
Somebody from the public.
They wouldn't even knew anything about it.
Apparently came in, "I don't want to see that," or something like that
" steam coming out, anything out of there at this time".
So it 25 must have been later.
It had to be later.

We had hot well level back, though.
That's what I'm getting.
8, We got it back and we shifted it back and it was the second time we g
attempted to do that and I'm not sure why.
And I don't know if it was me now.
That's what so bad about this.
I can't remember doing it the second time, but I can remember it struck me so funny...
I hate to u'e that term right now during this, but that somebody was calling us s
from outside telling us not to dump anything like that.

HUNTER:
How did you shift from the atmospherics back to the bypasses?
g Do you do that by switching or restarting the circ pump or -
g 20 FAUST:
Starting the circ pump remakes the ir.terlock that's between it and shifts the control back over.

How many did you start?
Restart? One?

In the chronology, we can key to tLit because we can see on 5
the computer when the pumps were restarted, so we --
6 FAUST:
I see what you are trying to say.
I'm pretty sure we put two 7
back on.
8 9
HUNTER:
But that will let us key to that.
But it was at that time, 10 though, that you saw Bill back, that you recall seeing Bill Zewe back?
11 12l FAUST:
Right.
13 14 I
HUNTER:
- 0. K.
Now, basicaHy the secondary was - you had the primary isj problem. 0.K.
And the secondary was there, and you had trouble with the B steam generator, or apparent trouble?
18 FAUST:
Well, OK.
When I initially -- right off when I got the flow g
back, B seemed to be coming up, and I was throttling back was before I even got up to low level limits there.
As soon as I started seeing an indication on the generator, I started throttling back on it.
And I got to the point where I shut 11.
Levels kept coming up.
Drifted up above 30, so I got up to about 35 and I said -- well, at first I 24 thought maybe this thing is really expanding or something, in there 25
j 43 l
l 1{
and it's just pushing it up.
And I shut 12, it would have been 128 2
isolation, EFV 128.
Then the level still came up.
I ended up, got up i
I 3
to about - I guess it got up around 45 inches.
And I was then worried 4j about really sub-cooling possibly - and giving them a harder problem 5
on the primary with pressure.
So I isolated a third valve.
And it 6
helped.
Well, it sort of drifted it really turned the rate at which 7
it was increasing till where I was paying attencion to the A coming up 8
and that one pretty well, I was able to hold the 11.
Throttling back on the 11.
I want to say something.
g 10 HUNTER:
When did you notice -- at this time did jou notice the reactor 1 11 building pressure changing?
12 13 FAUST:
Not during this period.
What I was looking at - some many g
other things that I was looking at - like, I was looking over the 1q.j NI(s) to make sure they were down, where I thought they should be, which in other words, it's like two to three decade drop right off.
g And just traveling down - it came down, which at that time was looking pretty good.
I got it into the EP at that time.
Somewhere in here I g
got under the EP, because I remember looking over the EP for the initial parts of our sequence that we wanted to cover on our reactor trip.
Then I never got fully through followup actions on it when I got involved back on the panel again.
And I also -- now this was later, this was another one even later on.

5 6-MARSH:
- 0. K., thank you.
7 8
FAUST:
I guess it was -
I'm losing out my train of thought where I g
want to go right now.
It just seemed to hold there for a long period of time.
They got level i~ndications back on the generator, the pressurizer.
10 I think that sort of made us feel like maybe we never lost it.
That 11 I
12l there wa's still some sort of a bubble in there.
At least, that's what I was thinking.
'Cause although we had a hard time holding it - I 13 don't know whether everybodys' suspicions were at the time - but I p
knew we were having a problem with high level in the pressurizer, 15 which was abnormal for what we were going through, for what we should li have been going through.
It seemed like we should have recovered it.
And I think this was getting pretty well onto where we started noticing 8
flow in the RQ pumps more and it was dropping off and it also, the i
g fact that we had all the alarms on the RC pumps up there vibration l
wise.

1l HUNTER:
Were you getting orders from more than Bill Zewe?
i 2l 3;
FAUST:
At this point the orders were coming from, at least on this 4
particular thing, we took -- maybe I should redefine something.
The 3
R0 takes immediate actions, right.
We get back up then, we all work 6
together to put the information together and recommend the best way we 7
can see to go on something, and that's the best way I say it, I guess.
We were making recommendations and we all come up with the same reasoning 8-g' that we wanted that pump going anyway.
Try to get it back on the line.
10 11' HUNTER: 'You saw the NI, the nuclear instrumentation Intermediate 12, range and the source range?
13 14 j FAUST:
The source range first, then the intermediate range.
15 16' HUNTER:
You saw it dip? What was next, what was the next thing that g
you saw or that you recall at that time?
yg 19 FAUST:
That's where I can't remember what I did exactly...
Oh, okay.
We just started a pump.
There's a hard part here on time, but the next thing we really started, like I said bef re this, we had noticed or indicated that intermediate let down coolers had alarms on 23 the rad monitors back there, as' far as the secondary closed side of it, which we pointied out and reasoned that due to probably the location e
4 4
%.y.
I i
54 i
1!
of the... just due to the location of those detectors, which are down 2{
by the let down coolers, were outside the room from it but they're 3l down in that area of the let down coolers - the sensors are - that 4
just hign background was probably setting it off at this time, down Si there.
There's things I'm missing right now because I can't remember 6
when we started seeing building pressure come up, because at the time 7
the answer that I got back, I said, "why the heck are we getting 8
that?"
It would indicate a leak in the heat exchanger to me, going g
possible leak.
And we really didn't have any problems with the level 10' on the intermediate closed surge tank to indicate a prim 3ry secondary leak on the let down coolers.
So, it was just reasoned out, it's down 11l h
near the sump down there and it's high, probably high background right n w because we were dumping water in the sumo.
13 14i HUNTER:
Being high background, would that mean that it was primary 5
1 coolant to you, a radioactive coolant of some type?
16 17 FAUST:
Yeah.
It would have to be.
To tell you the truth, I figured it was... at the time I thought this, but I was thinking that was g
sort of -- I hate to 'say this too -- but that was sort of an intermed-fate problem to me, to what we were having out front.
So, it was said high background, and for some reason, I visualized a lot of crud coming out of the system because of the thermal shock we had just put it through, and probably coming' down in through the let down coolers.
You really have to get into it.
I don't have a real feel for what

kind of curie content, microcuries, you'd be seeing in this crud cf I

f 4
5 HUNTER:
But that was your reasoning at the time then?
I 6

That was mine.
I just let that go then, to that point because, /
.s 8
the way it looked, we didn't have a leak from the surge tank level,,.

I ended up -- I was monitoring the... we 5
were just trying to hold where we were at now, is what it amounted to.
6 Trying to still get pressurizer level to go down and just remove 7
whatever heat we could, because this is the time period now that I saw 8
we were cooling the TC down and we couldn't. get T hot to come down.
T hot, when we stopped the pumps initially, went offscale high.
They g
claimed that, at least up in the panel.
They said they could still 10 :
see it on the -- we have a trend recorder over on panel... it's over 11 12l by panel' 8, to the left of panel 8, whatever the panel number is on that.
It is used to, it monitors some of our primary components, 13 radwaste and turbine supervisory things.
I don't know who was over 14, there looking at it, but he said he could just barely see it, which

I know Ed ended up, when we were sort of stable, ended up going behind and, I think this g
was before even, looking at the. RC drain tank.
He was doing some other things at that time, too.
So, one of the problems we were starting to have was with building pressure, now.
It was gradually coming up.
We still haven't had a 4 pound actuation yet on the isolation.
We had other people in because I was - I turned over the feed station and I think I. turned it over to -Len Wright - I believe he is the 19 operator that showed in.

5 We started trying -- of course, the ultimate thing was to try to get I
6[
pressurizer level, get pressure up and temperature up in the pressurizer.
7 Just get control of the plant, is what it amounted to.
I was taking, 8
receiving orders from -- I hate to say it because I can't even say the g
supervisor -- it must have been, it must have been Bill.
Because they were sort of in a conference behind us...
For the life of me, I know 10 11 I was on the make up panel.
I can answer some questions about that, but I can't answer what was going on behind.
I know I asked questions.
12 I think I asked why we were doing it, but it was.like one of those 13l things.

We couldn't g
10 g too low because we were trying to maintain pressure too in the system.
It almost ended up, you know, in a balance.
You still have 11 lu,,1 an indication of pressurizer level, and you're icw, you're down on pressure where you don't want to be.
You're down right around at 13 saturation, or whatever that.

At this point, it was, the flow was about 300 gpm.
Because I got the word to throttle on two odd valves.
I got the orders to shut 24 C, no B and 0, and throttle on C and A.
I think I got them right f

questions I couldn't figure out - I wasn't sure what they were trying 3
to.

somebody can figure out who they are behind there.

were involved in it at this time.

Where's he at?
g 19 MARSH:
That's not all of them.
20 21 FAUST:
Okay, Mike Ross.
I believe that it was him that indicated to throttle the valves in the position I had.
I had taken one of the 23 makeup pumps off, purely because of getting down to a lower flow rate 24 that I was throttling, I only needed one pump on.
It was then that I I
25 e
u il J
l 63 i
1l was actually shifting pumps.
I took one off and I got down to one i
2:
pump supp'ying 300 gallons, at one point.
I had taken "C" pump off, I
3 before -- this is what I mean, this is when I have a hard time remember-4!
ing -- I ended up somewhere in there I had the A makeup pump on, 5
supplying, and that would just be through the A and B valves.
I I
6i restarted C and ended up throttling on throttling configuration of 7
supplying 150 gpm, approximately.
They told me to try to shoot for gj 100 on the loops, and I couldn't get it down.
I couldn't fine -
throttle it that low, and I ended up, I was always putting in at least g
300-400 gallons per minute because it was too hard to get down.
I 10l 11j just couldn't get it down that low.

It's not 40, it's g
9 18 19 HUNTER:
What would that indicate to you?
Do you have any....
21 FAUST:
I thought it was, at the time I thought it was probably steam, but then it didn't seem to reason out to me because we had both let 23 down coolers on and temperature in the intermediate was low, so there is no reason for that.
And then I started thinking, maybe we were 4
{
64 l
1!
getting a lot of solid partic-- no, what I was starting to think was a 2.
crud buildup possibly in the let down lines, to where it was actually 3,
starting to block it up for us.
Along those lines, I even started 4
thinking, well maybe somehow it's solidifying out, baron was starting 5'
to solidify because we had such a high concentration possibly in 6
there, at this time.
7 HUNTER:
Questionable.

15j same pe pie are still present.
Donein, you still had questions when We broke.
I'll turn it back to you.
t 17' HUNTER:
Okay.
We were talking about the let down flows fluctuating 20 gallons per minute, around 40 gallons and you were indicating that g
it might be due to high boron concentration.
What did you do then?
21 FAUST:
Well, I didn't do anything really.
We were just monitoring really.
I was sort of taking r,eference from Fred and just listening 23 to him calling out what, you know.
Pressure seemed to be holding 24 around, it was around 1200 -- I can't even say that because he was 25
i 65 r
li sort of glued in that corner.
The main thing I was trying to see is i
2j if we were getting lead way at all in pressurizer level and T(av), if 3}
the thing was starting to cool down at all.
There was debate on what l
4l to do, of course.
Ideas we're coming up, try'ing t, with the possibilities 5
of going on and trying to get the core flood tanks to flood into it.
I actually can't tell you everything that was going on, as far as the 7
reasoning going on, right now.
8 HUNTER:
During that period of time, you' re sitting.....
g 101 1
11l FAUST:
I actually ended up being just a monitor, because all I was doing, at that point in the game, was controlling the makeup pump because we needed it for the flow they were asking for.
13 14 HUNTER:
Okay, and the flows that they were asking for were, like you 15 mentioned, the odds throttling, trying to get down to the 100 per loop, but you couldn't get down that low on 2 valve, so you were...
g 18 19 FAUST:
I was calling back, I think it was Brian Mehler was back i
there.
He was trying to pinpoint the - you can't see the gauges too well from over the panel there.
He was just trying to tell me when I was. hitting it.
Usually, just tweeking on those valves when you get 23 down'that low, you either go all the way one way or back up to 500 in 24 one loop.
It varies.

Two flow 1
3 paths for makeup, the normal makeup valve, okay - what would be the 4;
maximum and minimum flows you would normally ever see through-that 5
flow path?
In other words, if the pressurizer level is low, then that 6
valve could come open and you could have one or two pumps pulling the 7
water and then charging into that flow path.
8 FAUST:
Let's put it this way.
If that's 17 -- and we've experienced g
this in the past, it is the only was we can reference it to you --
10 11, right now, the.17 is shut, 'cause it's seeing a high level.
12 HUNTER:
Right.
I understand.
13 14 FAUST:
If that valve were to open wide, you could put in six, seven 15 hundred gallons going in'through there.
The way I can reason this out 16 is because we've had, we had a trip once.
We actuated ES and we g
Weren't getting any flow in the one loop indication back thera, and it turned out that 17 went wide open and just robbed the flow from that g
path and put it in through B high pressure injection loop but just took it away from that side from seeing a lot of it in through the A.
-22 HUNTER:
Okay.
And on the normal.-... the ESF valves, the 16 valves - A, B, ~ C, and 0 you indicated that you couldn't get down much below 4 -- er, 100 gallons on a. valve.
Can you --

HUNTER:
You said you shut' two off and you had two throttled.
8 g'
FAUST:
Right, that was this odd combination for what the reason they had in mind.
I guess it was just try to hold long enough so we could 10l I
see, I guess so they could have more time to think about what was 11 l
12 9 I"9 "-
13 HUNTS:
Okay.
I'll drop'it at that point and, again, I need to come 14i back to those details and we'll come back and discuss that area, to 15 try to establish the actual flows, to the best of your recollection, 16 One point, you're receiving instructions from someone at that time, y7 either a group or Fred Scheimann?
I mean...
19 FAUST:
Fred was pretty well tied up on the pressurizer level controller.
This was coming from Bill and Logan, I would say, and probably Kunder, back in the back discussing this.

0.K., good.
No problem.

There was other people -- in fact, there was a big meeting l
2 back in that room back there.
3 4l MARSH:
What I would like to do is switch over to Larry Jackson at l
Sj this time, and when Larry's finished, if depending on how you feel 6
Craig, if you would like to return and discuss the loops some more, we 7
could continue.
But if you begin to feel fatiqued we will rap up with
~
8 Larry.
So I'll let Larry take over from here, now.
The time is now g
5:17 and I'm reading 600 on the meter.
10 ig.
Craig, I've got some questions that relate to emergency JACKSON:
planning, effluent control, and a couple questions related to health 12 physics; and I know that you had some pretty specific duties in there, 13 14l and some of these may call for subjective answers instead of hard data.
So if I ask you a question and you don't know the answer to it, 15 16l that's fine.
If you've got an opinion or you've got an idea of what was going on, I would appreciate you putting that down, okay?
The 77 first question is - when in the sequence did you start getting radiation yg.
monitor indications that some type of release of radioactive material
. g j
from the reactor Coolant system was occurring?
I know you mentioned the intermediate cooler monitors.
~
21 22 FAUST:
Letdown coolers.
That was before we even took the pumps off -- I believe it was.
It's 'in question -- that's a hard one for me to answer.
Those two, I just remember them being there, and they were e
i f
-l 69 i
lj there, that we were at a point where we could say, we could at least 2
say, like, "we got these alarms - what could they be from, or what 3
kind of problem are we involved in here?" We made some checks on them 4
to at least say that "it's' not getting out into the system.
It's 5
still in the primary" to us.
That was my indication anyway, if it was 6
staying in the makeup' system, as far as I was concerned.
7 JACKSON:
One question on those let down monitors, or the intermediate 8
g cooler monitors - had those things gone off because of high background before, or is this something that --
10 11 r
FAUST:
No.
It never happened before.
3 13 JACKSON:
This was the first time so you were having to make a judgment 14 15 16 FAUST:
Yes.
18 JACKSON:
Was there anyone, in particular, monitoring the radiological conditions?
Is that an assigned? function of one of the operators?
21 FAUST:
It's not an assigned function from the fact that, if we think we have a problem and the problems are initiated by alarms, really on 23 the'back panel.
The first one we got didn't really show us that we 24 were having problems radiological wise, but I can't tell you when...
a h
70 1
I can't really say when - I think it was when we got the alarms initially I
gj that we shut our ASV-53 or -23, which is out steam supply to Unit 1, I
3; which get on their boilers pretty quick over there, because we just 4.
cut them off.
We called them, they knew that we had a problem now, 5l and they had to go on their own from there.
We were supplying our own l
61 steam from what we were pulling off the generators.
I 7
JACKSON:
Did you ever -- was there a point somewhere where you saw a 8
radiological condition developing in the plait that was abnormal or, I r
g know that you mentioned earlier that a lot of the alarms just - bang, 10 they were there.
Did anybody, to your knowledge, notice any trends 11 bef re this all happened?
12 i I
13 FAUST; No.
We -- the first indication to get our eyes back there w uld been an alarm.
We didn't receive any except, like I said, I 15 can't place how exactly when it was, the intermediate?
I know it was 6
beforethe rest of them and it was in for -- I can remember it being in for a While.
That's really about all I Can say to that.
19l JACKSON:
Did you at any time get a notification from Unit 1 that their releases were going up, if they were seeing anything on the monitors?
22 23 FAUST:
No.

h A
I l

I 71 l
11 JACKSON:
What considerations were given, during this time, to such 2
things as reactor coolant drain tank pressure, or level increases, or 3l to the reactor building sump levels - did somebody look at those or i
4j see?
Sj 6'
FAUST:
This is what "m saying...
This is even later than Ed Fredricks 7
was looking, looked at one thing he was at was the RC drain tank.
I 8
don't know what time period this was really, but that was one thing he g
was looking at.
10 JACKSON:
I'm kind of covering more...
Don't restrict yourself to 11l' just this immediate time frame here, when everything was going haywire, 12 because I'm really looking at a longer time period than dorwin, okay?
13 I'm trying just to following things up to the 31st, where they are 14 restricting themselves to looking at a pretty nar ow time frame now.
15 1
5 if y u think of anything that falls out of that time frame, that's 16 fine too.
g 18{
FAUST: Something you might -- as far as monitoring meters, I can't 19 remember when Hugh McGover'n came in, but he was one of the persons that... I just have it on my mind -- we got the alarms and Hugh was there.
That seems to be the way I remember it, because he was monitoring the back panels then, as far as radia' tion monitoring alarms, marking 23 the ' harts, and then trying to keep... trends were all pretty high at c
24 that time... it wasn't a trend, I think it was a step change.
So there wasn't much for him to monitor.' There never is.

He is a CRO.
He was to be our relief coming in at that time.

Yes.
I could be wrong on that?
I was relieved by another shift, really, so I could be wrong in that.
But, he was there, that's all I~can say.

JACKSON:
To your knowledge, do you know when anyone started looking at the indications with the ideas of classifying the situation as an 12 emergency? What keyed them to start doing this?
13 14 l
FAUST:
It was pretty instantaneous.
.15 l l
16 JACKSON:
Are you talking about radiation, instantaneous with relation 17 to --

6 FAUST:
No.
1 7
8 JACKSON:
OK.
9 FAUST:
At least, to my knowledge, let's put it that way.
10 11 g
JACKSON:
Do you recall a point when the decision was made -- well, y u've already answered that, I think -- when the monitors when off, 13 what was the declared first, a site emergency?
14 i I
15j FAUST:
It was a site emergency, and it seemed like it was very --
6 almost right after that it was declared a general emergency.
g 18, JACKSON:
Okay, so very little time was between the site and general.
g 20 FAUST:
Yes.
21 22 JACKSON:
One question in relation to this, going into the emergency 23 plan organization here - there's been some question about the supervisor's 24 role in contacting people - did you have enough supervision at this 4
5
I 75 ilj
' time or, maybe.I should have said, did you have too much supervision 2!
at this time?
I know you had a lot of people in the control room.
i 3
4j FAUST:
I'm not sure what k'ind of answer I should give there.
5 6
JACKSON:
Well, I'm asking for an opinion, really, OK?
7 g
FAUST:
I really don't like to say one, because.
9 10-JACKSON:
Okay, that's fine.
Let me ask you another question then.
11' At this point, what is your opinion about the number of people in the f
control room? Was the crowd managable, or was it causing, giving the 12l perators problems?
13 14 15l FAUST:
It's the first time I've ever hit it from this side of it, so 16l I'm n t sure how to answer it.
I wasn't in any... I had all the room I needed.
I didn't seem to... if I wanted to say something, it p
Wasn't ignored; as far as saying it, they were going to listen.
The only thing I remember saying is that before we turned the RC pumps g
"9
- Y "E
20 those pumps off, and nobody else did either, I'm sure.
But, the direction was to try to go on to natural circulation.
We had indications we'were going to lose the_ pump, maybe A pump. or naybe all of them.

MARSH:
To maybe put you a little more at your ease in answering i
2i these, remember, the purpose we're asking these is not to focus the 3
blame on an individual, but to draw from this as much constructive 4
information as possible for the future.
So we are not after you to 5
say well, so and so didn't do this or so and so didn't do that.
We're g
trying to get a feeling, a. flavor over all that we can draw from your 7
experiences, to make things better, should we have another occurrence.
8 And that's why we're looking for your feelings.
So don't feel we're g'
trying to place blame at this point, but more to draw on your experience.
10:
And only you went through it at this time.
So that is why we' re 11i asking it in the manner we're asking it.
l 12l FAUST:
Well, I guess I'd say, it seemed like we had a lot of input 13 that... what bugged me is that I didn't lih them going back in the 74 g
room and discussing it.
I know what their reasoning was, and maybe it's better reasoning, I' don't knoW.
But it is to try to -- they were holding the plant out there, try to get here and think over what's 7
going on out there to get a good answer.
I'm sure that's the reasoning behind it, probably.
So we were just standing out there, trying to hold on to it, so to speak.
The idea is I can see what they were i
doing now - they wanted us to hold it, try to hold it to give them enough time to try to reason something out.
We were the first line.
We were right there on top of i-t, looking at the thing, and somebody's got to back off and try to see it from the overall view point.

MARSH:
Has there been any discussion among the operators since then?
2.
In other words, separate from that of the supervisors, have you discussed l
3!
this among yourselves?
Do,ing this and that?
4 5
FAUST:
We talked about the accident among ourselves, I mean as far as 6
trying to reason-out what'.s happened.
7 8
MARSH:
I'm wondering, was there any feeling that -- do you feel that g
the operators have more of a hands on experience and definite knowledge 10 of.what was going on at the plant and the supervision may be a little 11 more divorced from that, and that maybe your input should have been solicited more?
12t 13 FAUST:
I don't know if I really feel that way or not.
14 15i MARSH:
I was just curious to see.
16 17 FAUST:
That's been something bugging me.
If I were -- I think what 18, you're after, if I were there alone, would I have done something gg different.
I would probably say yes.
But...

JACKSON:
What are the normal lineups for the reactor coolaat drain g'
tank and the reactor building sump? Where do they pump from, no wait, 10) not from but where they pump to?
11.
FAUST:
They're usually lined up to go to the miscellaneous waste --
12 this is the miscellaneous waste holdup tank, I think it's called.
13 They're the same tanks, they do the same thing.
It's just different 14 names are used.
15 16!
JACKSON:
Both the sump and the reactor coolant drain tank go to the 17 miscellaneous...
g.
19 FAUST:
The reactor coolant drain tank goes to the RC bleed tanks.
g That would be... in fact, it goes to the vent header on it.
The sump g
pumps to the miscellaneous hold up tank and the drain tank goes to the bleed tank, which I believe was isolated because of high pressure in the tank.
I don't believe it does - it isolates itself on high pressure in the tank.
I think it's only like 5 pounds in the tank or something, 25 and it will shut and isolates it.
l a
I
[
79 1
JACKSON:
What actions were taken to try to contain the radioactive
}
2 materials, now?
The question is what pumps were shut off? Were there 3
any valve lineups changed to divert water to different places?
4 5
FAUST:
At the time there wasn't... at the time when initially no 6
alarms were in the Auxiliary Bu.ilding...
I think it was, I can't 7
really answer this, I can just tell you what I know.
We shut off the 8
RC sump pumps.
They were shut off before we had radiation alarms and I believe before we shut the RC pumps off.
I-can' t, I can just locate g
it that way right now.
This is purely later on... this is something 10 that'Ed had have done when he was over there.
He had been, like I 11 12 said, he went back and looked at it, and I don't know if it was then r if it was even before then, that he had this done and was referenced, 13 f
and when he went back around and took a look at the RC drain tank to 3
I see what the conditions on it were.
151 l
16 JACKSON:
Once you had the alarms, I guess, what actions were taken to g
try to limit releases -- Ventilation system, isolation, and this type?
19 FAUST:
Ventilation system - did as much as you could do on it.
The 20 fans shut down and your suction and discharge dampers on the ventilation 21 l
unit trip off when the upstream monitor alarms high.
It just shuts the whole thing down, ar.d it did that.
And so you're sitting dead over.there, basically.

JACKSON:
Do you have any knowledge of radioactive materials, liquid 5
2 or gases, how they might have been transferred from the reactor building 3
to the auxiliary building?
...I'm tilinking like, you know...
- Well, 4
go ahead l
5 l
6 FAUST:
The only thing I can th, ink of is that init' ally the RC pump, 7
before we shut it down in the early stages of it, did pump to the 8
miscellaneous waste tank.
The only other thing I can think of would g
be that we -- that's manual, that would have been done manually.
10 N body pumped it down.
It would be the pump down in the RC drain 11, tank, at least at this time, there wasn't any pumping now like that.
h 5 the sump pump did pump automatically and it did put it into the 12 l miscellaneous waste hold up tank.
And a thing that I can't figure 13 out, once again, we were sitting down just discussing what nappened g
and trying to figure it out ourselves.
We couldn't figure it up to 15 the tank level indication prior to and after, never indicated it never 16 overflowed.
So, whatever came out should still have still been in p
that tank.
18;.
19 JACKSON:
You mean "in that tank", you're talking about the miscellaneous waste tank?
21 22 FAUST:
The only other thing I can think of is a relief lifting in the makeup, the letdown line in the makeup system, possibly.
Like I said, we were getting surging.
And that goes to the vent header of bleed e
ti Il i
h 81 il 1!
tanks.
And it's a loop seal on that -- it's very possible that seal 2
was loose somehow, and we started putting water... maybe water got 3'
out on the floor or into the system that way, I don't know.
I don't 4'"
think they can get in there yet to determine that.
The thing would 5
have resealed itself anyway, just from operations that we're doing 6
now, we still, we can hold the. pressure on that vent header.
You 7
know, we proved that later'on, so that's telling me we did put a lot 8.
of water in through that header, through another problem we had earlier.
9 It's really a mystery to us, too, how the water got out there.
We 10 can't figure it out ourselves, for the most part.
11 MARSH:
You say you had a problem earlier - a.e yo i talking during 12l i
1 this event, or are you talking of a date previous to this.
When you 13 said about the seal repressurizing itself now, you had had a problem.
14 15f ST:
This was, I was on the panel that day till about 3:30-4:00, so 15 17 j I went home.
When I came back on at the 11:00 shift that night, and earlier that morning then, just before I got off shift again, we ran 18 into, that's when we started making the initial releases.
Because of g
the problem we had.
To me, it got pretty serious, and I didn't want 60 to loose what we had.
22 JACKSON:
Do you know of any liquids being pumped from Unit 2, say
(
from turbine building sumps, or any other sumps, to the industrial waste treatment system, or Unit 1 anywhere else?
e
l.
82 1
FAUST:
The only thing we had going to Unit 1, and was terminated 2 ;
right away, was -- in fact, it was coming to us from them, was condensate 3
returned.
We were sending them steam and getting it back, and it was 4
isolated.
The condensate return went right away because of problems
~
5 with the hot well.
Steam went, as soon as we had problems with...
6 well, we had the trip and Unit 1 was getting their boilers up, bringing 7
their boilers up, which is normal in something like this, on just a g
regular trip, let's put it that way.
So we could be supplied.
I gl don't think we actually isolated it until we got the radiation alarms, l
10' then we secured the steam from Unit I and we made a brief announcement telling them, with a phone, I'm not sure how quick it was done.
17 That's one of the things we've got to get off the line if we have a 12 problem with radiation.
And the liquid release was terminated right 13 gl away into the river that Unit I was making.
That's another thing that I
g t done pretty quick.
15 16 JACKSON:
One question regarding reactor coolant drain tank.
If that
~
tank - I mean, not - well yeah, the tank or possiL ly even the sump too - is it feasible that if those pumps are turned off manually and g
the lines are not isolated, that the pressure in containment could c0 keep the flow going to the aux building?
22 FAUST:
I don't think it got high enough at that time to do it.
It was only 4 pounds.
The only other thing we had was this spike in the building, which I believe now we are interpreting possibly to a hydrogen 25
ly i
l' I
83 l
l i explosion.
That was beyond, we had this problem in the aux building 2
before that.
I would say no, because its got to -- the line's got to 3
pump up to the..
4, 5l JACKSON:
Possible, maybe due to siphon effect?
6 7
FAUST:
Wel1, maybe... I don't know.
8 JACKSON:
Does the pumping go about the same level?
g 10 FAUST:
It might have.
I guess it's feasible.
12 A GSON:
Okay.
13j 14 AU erry Daughedy sM, isolated some vahes associated 15 with turning the pumps off.
You can verify that with him.
16 17 MARSH:
Okay.
We're at a breakpoint, I would like to terminate this 18 tape at this time.
The time is 5:41 and I am reading 934 on the g
meter. I am going to shut this tape off and replace it with a new tape.
The time is 5:42.
It's April 21, and we are continuing.
This will be the third tape on an interview with Craig Faust, being conducted at the interview trailer NRC is using at the T'iree '4ile Island site.
This is Bob Marsh.
I'm accompanied by Larry Jackson of NRC and Dorwin Hunter, and.the fourth person in the room is Craig Faust.

I'm switching the questions now to a couple of HP type j
5 qjestions.
Did you enter the Auxiliary Building anytime, from the l
6 morning that the incident occurred to 3:31, which would have been -
7 Saturday, I guess?
8 FAUST:
On Saturday.
No, I don't believe... I went in but I think it g
was, like five days later, four or five days later.
10 '
ll i JACKSON:
Okay.
Do you know other individuals sent into the auxiliary 12 building on your shift?
73 l
14 FAUST:
I believe...
You mean after the accident ~
15 1G JACKSON:
Yeah?
The morning or up to, say, the 31st.
p
~
10 FAUST:
To tell you the truth, no.
I said, I'm pretty sure people g
went in, but I can't say who, or when they went in.
u0 21 JACKSON:
Okay.
23 FAUST:
And I was.1't really thinking much wrong with entering into the auxiliary building, for a while there.
Other. people were taking care
~
of that.

JACKSON:

HUNTER:
You indicated that you worked from 11 to 7, then you went in 4
and worked from 7 to 3, so you completed a 16 hour1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> day on the 28th?
5 6
FAUST:
On the 28th I worked my normal shift,11 to 7.
The accident 7
held me over till 3:30.
8 HUNTER:
Okay.
g 10 FAUST:
It just, you know, the reason is, you don't turnover on something 11 like that till you are somewhat in a stable condition, if you can.
12 Otherwise it gets extremely ridiculous.
13 14 HUNTER:
Okay.
5 16 FAUST:
That's my feelings on it, anyway.
g 18 HUNTER:
Okay.
At the time that you were relieved at 3:30 that day, 19 I
were you still on makeup panel?
20 l, 21 FAUST:
Yes, I think.
I must have been on that makeup panel there...
I can't believe it, I must have been in there for four or five hours, I guess, four hours, where we just folded.
I'm having a hard time seeing it being that long, but that's when I got relieved, I was there, and it was around 3:30, more like 4, when I left, around there.

86 4
l If HUNTER:
Okay? Do you recall turning the pumps off during that time?
2 3
FAUST:
During that time I was on it? Oh yeah.
4 5
HUNTER:
A number of times?
6 FAUST:
I started and stopped the pumps as, like I said, when flow 7
c nditions that I was required to maintain provided for it.
It was 8
either backed off on it to where one pump was easily within the range 9
f what I was supposed to be holding or you know, when they gave the 10l 11;i w rd to go higher and especially when we split, I was on -- I went d wn to one pump initially when I was told just to hold.
When we 12 shifted, I started the C pump...
There is a problem with me that I'm 13 trying to clear up now.
We ended up on the B pump. I keep getting the feeling I never stopped the C pump, that the one I took off was the A, 15 because I ended up trying to start the A, and it never started, and I 16 went right to the B.
And as far as I know, tre A nump may not start yet.
18 19 HUNTER:
Was there any time where you secured all the pumps or had them all off?
21 22 FAUST:
No, I always had one pump on at all times, that I can remember.
I I can't remember securing all the pumps.
I throttled back heavily 24 when we tried to go on the core flood tanks.

HUNTER:
When you ended up on the makeup, were you keeping your own 2
log'or was somebody writing the pump starts and stops down for you?
~
3 4
FAUST:
I don't think anybody was keeping a log at this point.
If 5
they were, I didn't know about it.
It's something, I think we should 6
have been, but...
7 8
HUNTER:
Okay.
9 FAUST:
Nobody was logging anything that I know of, in relation to the 10 11 pump starts.
One thing is, you sort of rely on the computer for
~
something like that.
You can go back and pick it out, you know, start 12
),
and stop ti,aes on' the pumps, what's on and off.
13 14 HUNTER:
Okay, I would like to leave it at that point and indicate 15y that I want to get back with you, and at that time it will be at some 6
specific points, and it would be to include your continuing the make-g up station, apparently from early morning until way late in the afternoon, 8
and see if we can't work our way through that okay?
g 20 FAUST:
Yeah, we have a lot of people who are in this.
I'm sure you can tell that they will be able to help and correlate this.
I can't remember stopping all the pumps, and for some reason, maybe I'm just blocking it out, but I can't remember doing it.
I remember, and like I said, I'm.getting the feeling I had, I went down to the C pump, not
88 1
like I remember saying I had it before because of what I did, trying 2;
to get the A back, and I ended up putting the B on.
I don't think --
3 I know I talked to people or mentioned it to somebody, and it's something 4
that I'm going to mention again, that that pump might not start, that 5
A pump.
I don't know if we know if it is going to start or not, yet.

HUNTER:
When it tripped, is it damaged?
8 FAUST:
This is what I mean.
All I know is, when I tripped it, it g[
went off properly and I had the lube oil trie pumps on.
It's when I 10 went to restart it, later on, it didn't pick back up.
11 12 HUNTER:
So it's sitting down there the way it was when you turned it 13 off?
3 15 FAUST:
As far as I know, yes.
I don't know if anybody attempted to 16 start it since it's a good point, I'm going to bring it up.
18 HUNTER:
Okay, keep the makeup system in mind a little bit, and be aware that we need to go through that, because you are the flow recorder 20 ;
on the makeup system from this time to this time.
Okay?
You know, 21 I'm just trying to,~ we need to know the makeup flow, as best as we can recall.
So we'll specifically get at that, not a pressure point at 23 i all, but just something that, you must realize that we need to sit down and go through it and reconstruct it as best we can.
And I'll 25 I
!i i,
h 89 i!
1]f have the chronology, and we'll go through it and spend an hour or what 1:
2[
ever, going through that and try to recover all the data that we can.
I 3
4 FAUST:
Well, it might help,- definitely.
I know what prints I have 5
been able to look at, did help relate to me, once again, time periods 6
that passed.
I can't believe it went that way.

HUNTER:
I have no further questions.
Larry, do you have anything else?

15l anything else you want bring up or talk about before we finish up today?
