1 RESNER:
The following interview is being conducted in Trailor 203, which 2
is located just outsid9 of the South Gate to the Three Mile Facility.
3 Today's date is May 24, 1979 and the present time is 1:55 p.m. EDT.
This 4.
is an interview of Mr. Douglas Earl Weaver, Jr.
Mr. Weaver is employed 5
with the Metropolitian Edison Company at the Three Mile Island Facility.
6 His job tit!e is Instrument and Control Foreman.
Individuals representing 7
the NRC present for this interview are Mr. James S. Creswell; Mr. Creswell 8
is the Reactor Inspector with Region III of the Nuclear Regulatory Commission.
g Also present is Mr. Anthony Fasano; Mr. Fasano is an Inspection Specialist assigned to Region I of the U.S. Nuclear Regulatory Commission.
Also 10 presenc, Mr. Donald D. Donaldson; Mr. Donaldson is a Radiation Specialist assigned to Region I of the U.S. Nuclear Regulatory Commission.
Monitoring this interview is Mark E. Resner.
I am an Investigator of the Office of 14l Inspector and Auditor, Headquarters, U.S. Nuclear Regulatory Commission.
Prior to taping this interview, Mr. Weaver was presented with a two page 151 16:
document, which advised him of the purpose, the scope and the authority 1
with which the Nuclear Regulatory Commission was given by Congress to conduct this investigation.
In addition, we have apprised Mr. Weaver that 18l he is entitled to a representative of his choice to be present during the interview should he want one, and also that in no way is he compelled to 20 talk with us should he not want to.
Also, on the second page of this 21 document, there are three questions which Mr. Weaver has answered.
I will 22 state them for the record.
No. 1.
Do you understand the above?
Mr. Weaver 23 has checked yes; is that correct Mr. Weaver?

Question 2:
Do we have your permission to tape this interview?
4 Mr. Weaver has checked yes.
Is that correct?
5 WEAVER:
Yes.

RESNER:
Question 3:
Do you want a copy of the tape? Mr. Weaver has g
checked yes.
Is that correct?

Yes, it is.
12 RESNER:
Okay.
We will provide you with a copy of the tape at the conclusion of the interview.
l4nd now, if you would Mr. Weaver, briefly give a synopsis of your educations 1 and your job experience as related to the job that you currently perforn.
16l 17 WEAVER:
Alright.
I was in the U.S. Navy for six years; Reactor Operator, Electronic Technician, 2nd Class, upon discharge.
I came to Met Ed, was 2nd Class I&C Technician for approximately 2 years; was promoted to an I&C foreman, February 1974; worked Unit 1 for a startup program; took it through 21 the first refueling; then I was transferred to Unit 2 as the I&C foreman 22 down there for taking the Unit 2 through its startup and whatever.

RESNER:
Alright, thank you very much, Mr. Weaver.
At this time,!1r.
2 Creswell has some questions he would like to ask you.
3 4
CRESWELL:
Mr. Weaver, could you tell us when you first learned of the 5
event that occurred on March 28, 1979?
61 WEAVER:
Oh, about 10 to 5:00 in the morning.
7 8
CRESWELL:
How did you learn of this?
g 10' WEAVER:
I got a phone call from Kent Bryan asking me about pressurizer level.
They had a reactor trip and the pressurizer level wasn't i dicating exactly right; if I had any fee' o-what could be wrong.
I told them no, not over the phone, I couldn't make any evaluation.
I decided to come out, I
look it over.
15!
16!
CRESWELL:
You said that he didn't believe the pressurizer level was acting exactly the way it should.
Could you elaborate on what he described to you?
20' WEAVER:
All the instruments were reading full scale which either indicated a malfunction, common to all three instruments, or a natural reading.
22 23 CRESWELL:
Did you advise Mr. Bryan of certain things that he could check?
24 25

WEAVER:
You go, you have your badge checked, your normal security checks 2;
through a metal detector, a normal entering type procedure wnen you go to 3
work.
4 5
CRESWELL:
Did you pick up a TLD at that tinie?
6 7
WEAVER:
No.
I don't think I did.
8 CRESWELL:
So after you went through the processing center where did you g
10 92 11, WEAVER:
12 I went over to the control room to see what was going 13 CRESWELL:
Upon your entrance into the control room, approximately how many pe ple were in the control room?
15 16 WEAVER:
There was about six.
18, CRESWELL:
Could you name them?
19!
20\\
WEAVER:
I think so.
Bill Zewe, Craig Faust, Ed Fredericks.
Okay, I'm pretty sure Mike Ross was in there when I, he was in there and George.
George Kunder might have came in later, I don't know.
So it was five or six.
And Fred Schiemann was in and out at that time.

5 CRESWELL:
1, Approximately, how long did that telephone conversation last?
2 WEAVER:
Not very long, maybe thirty seconds, cause I was already aware of 3[
4 the si>.uation and I told him, thank you-goodbye.
5 CRESWELL:
Then you got dressed?
6 7
WEAVER:
Got dressed and came to work.
g 9
CRESWELL:
What sort of conditions did you find when you arrived at the 10 security checkpoint? Did you come in the North Gate or the South Gate?
12l WEAVER:
North Gate.
i 14i CRESWELL:
Was it a normal situation at the gate when you came in?
i 16!
l WEAVER:
Everything was normal.
17l 18l CRESWELL:
Okay.
So you dr3ve your car on in to the parking lot and parked 19 it and went in to the access center.
Is th;t correct?
i 20' 21 WEAVER:
Yes.
First processing center, I believe is what they call it.

What happens whenever you get into the processing center.

1, WEAVER:
I told him that I had the instrument people take voltage readings 2
that were on shift.
I shouldn't say I did.
I thought I did so why don't 3
we strike that comment because that conversation that early in the morning 4
I'm not to with it all.
5 6
CRESWELL:
It's a possibility you nay have asked him...
7 WEAVER:
Normally I... My normal approach whenever '
_ t a call, I ask them 8
g' what did my people on shift do already, have they taken readings, stuff like that.
That's just one of my normal rections but I can't say I did.
10 11 CRESWELL:
Okay.
What happens then, after you get finished taking the g
telephone call?
13 14 WEAVER:
I got dressed and came in.
Well no, I got a call about 10 after 15t 5:00 where the control room operator from Unit 1, apparently unaware that I was called by Ken; he was in the process of calling in all the other super-visors that might be involved and telling them we had a trip to come out and respond to whatever necessary te do to help out.
l 20 21
- Let's see.
And did you name that control room operator?
CRESWELL:
22 WEAVER:
No, I did not.
I didn't catch the name.
We have a lot of new 23 people; it was an actual operator.
24 "O 007 25; I
7 1
CRESWELL:
You said Mr. Bryan called you.
Was he in the control room?
I 2
WEAVER:
Not at that time.
I think he was Reactor Unit 1.
3 il i
1 3
CRESWELL:
What did the control panel look like when you came into the control room?
6 7
WEAVER:
8 The items I looked at was only the control rods.
I looked for a full scram and the typical indication.
When I come in, I look at items for g
a technical area.
The first thing, when I come into a control room, I look 10 at areas that I have to work on during a shutdown such as an outage.
We have an outage list.
I did not look for plant conditions such as operations; I looked at the control rod drives to see if I had any PI problems; I looked at...
14 15 j
CRESWELL:
PI problems, would be position indications?
16!
17 WEA / ~R:
.. On the... right!
I icok for my normal green lights, my meters in the proper position, items like that.
I walked over and looked r
19{
I at the pressurizer level, did my comparison, took cc.nputer readings and the 20 recorcer reading, that kind of stuf f, t.) look for, if there was any problem 21 f
there.
22 23 CRESWE'jd Did you personally address data from the computer regarding the 24 pressurizer level?
25
""O 008 t

WEAVER:
Yes.
2 3
CRESWELL:
You called t:1e data up?
4 5
WEAVER:
Yes.
6 7
CRESWELL:
Did you call any other data up from the computer, that you recall?
8 9
WEAVER:
No, I don't think...
10 11 CRESWELL:
g Upon obtaining this information, you made a comparison between what the computer was saying and what the instrumentation indicated.
What was the result of that comparison?
i 15j DEAVER:
Then I looked at where all DP right from the computer and all 3 of i
161 the channels without any temperature compensation were reading what I would I
expect for the reading that I had on my recorder which was temperature compensated plus the reverse DT.
So everythi.ig looked like the transmitters overall seeing the same signal or they had a... common failure.
So every-thing was agreeing as far as the recomputer compared to the recorder.
22 CRESWELL:
Did you report that to anyone?
24
" O 009 2s I

WEAVER:
Yes.
2 3
CRESWELL:
Who did you talk to?
4 5
WEAVER:
Bill Zewe and the control room operator.
I can't remember which one.
That was reported that, hey, looks good to me.
6 7
CRESWELL:
Okay.
What did you do then?
g 9
WEAVER:
10 Well, I went downstair to look, to check for voltages, things like that to be sure that there wasn't something obvious that I was missing.
I 3
checked the ll5s, things like that.
We read right from the transmitters.
Just checked to see if there was anything that could effect all the readings.
14 CRESWELL:
This was in the cable room?
15j 16 WEAVER:
Yes.
17 18 CRESWELL:
And you would have checked by S Facts caoinets?
l 20 WEAVER:
What?
21 22 CRESWELL:
S--Safety Feature's Actuation Cabinet.

WEAVER:
No.
I just checked the p'1ssurizer level.
That was my concern at 2
the time.
3 4
CRESWELL:
Could you tell us what particular, is it power supplies....
5 6
WEAVER:
I checked the 115s volts to them and I checked their output to 7
make sure they had, the signal they transmit is -10 to +10, but I just g
checked at the actual voltage they were putting out, reading what the g
computer said and would correlate to what the recorder was saying at the temperature corrections.
10 11 CRESWELL:
12 Did you notice anything else abnormal while you were down in the Cable room?
14!
WEAVER:
No.

16!
CRESWELL:
Did you notice anybody down there in the cable room area at that time?
18 19 WEAVER:
No.
20 21 CRESWELL:
So, after you made these checks in the cable room what happens next?

WEAVER:
I went up to the control room and they were busy, so I just stood 6

in the background to see, if they needed me they knew where I was.
3 4
CRESWELL:
Did you report the information about the 115 volt power supply 5
to anyone?
6 7
WEAVER:
I cati't... I don't think I really did because if I would have g
found something abnormal I would have bothered him, but since it was nothing different..
g 10 CRESWELL:
yy What was going on in the control room when you got back up from y
the cable room?
13 g
WEAVER:
They were doing there plant operations.
They were running through.
Y #

They were looking at reactor building pressure and doing plant 16!
evolutions, which I don't feel I was qualified in
.. I tried to stay.in the background.
19!
CRESWELL:
How many people were in the control room when you came back up?
21 WEAVER:
I'm pre',ty sure that's when, I know for a fact, George and Mike were both there.

That's George Kuncer and Mike Ross?
2 3
WEAVER:
Yes.
4 5
FASANO:
What time was this at this point?
61 WEAVER:
It was around the 6:00 area.
7 8
CESWELL:
Okay, what happens next as far as your concerned?
g 10 WEAVER:
Well that's when I was able to ask Bill what F ought us down and he said we lost condensate.
13 CRESWELL:
This is Bill?
t 15j WEAVER:
Zewe.
And since there wasn t too much for me to do right at that 161 time, I said I going to go lcok around the plant.
So I went down and went to, now I might have my time frame messed up here, it might be closer to l
6:30.
19' 20 CRESWELL:
These are approximate numbers, we understand that.
21 22 WEAVER:
So I went down to the polisher panel and went inside the cabinet 23 and looked for water in the instrument lines, a probleia that I saw before, 24 and there was water coming out of the common regulator to the whole control 25 0
013 I
13 1
panel.
So I just made a peripheral walk of various other instruments in 2
that area to see how far the water got.
It was in that whole area, all the 3
instrumert lines had water cut of them.
So I, I can't remember if I went 4,
back to the control room and told them what I found, or went right down to 5
the instrument air compressors and the source air cc-oressors, and I did a 6
check down th-
- r..
I started blowing down some of the air receivere and 7
upeing how much water was there, and by that time Bubba Marshall, who is an g
aux engineer, I was working with him on a certain water problem from various g
times, trying to track down how it gets in and proving where it comes from, 10 that's when I called Bubba down and said, " Hey, Bubba, I've been blowing n
g down the tanks for 20 minutes and I'm still getting water out," and he came down and he assisted me, and about that time Donny Miller came and we Ju.t stayed there blowing down the water out of the air eceivers.
14 15,I CRESWELL:
How long would you estimate it took you to blow that water down?
16i WEAVER:
I never stayed for the whole blowdown.
I can't say.
In about 20 minutes I left.
I lef t it to the operations group to worry about that.
I went back to the control room to see if there was anything else I could dc.
20 21 FASANO:
This was about 7:00 then?
22 "O
014 23 WEAVER:
Yes.
24 25 t
i I
14 1:
FASAN0:
is1right.
To pursue a little bit more on the condensate problem, 2.
the condensate polisher, was this a problem that you had?
I gather it's a 3
problem you've seen before.
Did you come to any conclusions as to how the 4
water got there, how it got from the service and into the instrument air, 5
and how it, well do you have an answer now?
6 WEAVER:
I feel the Company has come up with an answer now.
I think they 7
8 did some verifications just this week.
They had found a leaky check-valve.
9 10 FASANO:
Is a check-valve in such a position where you can get from the, I gather the service air to the instrument air?
g 12 WEAVE _R_:, The check valve, if it was stuck open, would give you a path for 13 the water to go into the service air system and back through the instrument 14' air system.
Yes.
15!
16l FASANO:
Where would the water come from, the water that you four.d on March 28th?
Do you have any idea on how it got there?
19 WEAVER:
On March 28th I was guessing, because we never found anything positive that the water was coming from fluffing air, because every time they do that, the fluffing air evolution, well not e/ery time...
The other i
22' times that this problem occurred they were doing the same problem with the 23 polishers, regeneration, transferring resins, where they were using transfer 24 pumps; and just by that information you assume it comes from the water they 25 used when they transfer resins.
isnnU 013 I
15 1
FASAN0:
To go back.
You did go back and check the condensate polisher 2
panel and you did find air when you walked in the door?
I guess that's the 3
far door that you walk in and you tap it on that righthand side.
Is that 4
where the controls are that you are talking about?
5 WEAVER:
On the bottom, as you walk in the coor, there is a, 2 Fisher 6
7 regulators, and in series one of them is a water moisture separator, which had water in it.
8 9
I FASAN0:
10 That's about 3 inches, this water separator?
11 WEAVER:
Yes.
13 FASANO:
And about 1 inch in diameter I'd say.
Okay, did you check the I
front panel to see what the status was?
15j 16 WEAVER:
No, I didn't.
18 FASANO:
You did not?
19 20 WEAVER:
No, I was concerned more about the water.
The plant was already 21 down off the line.
I'm not an operator; I don't feel qualified to do work 22 like that.
23 24 "O
016 25 I
I,
16 1
FASANO:
When you do have water get in the line as it did, as it apparently 2
did, what happens to the inline valve and the outline valve on the polishers?
3 4
WEAVER:
From experience, they go shut.
5 FASAN0:
This then would block water passage to the booster pumps, is that 6i 7
correct?
8 WEAVER:
Yes.
g 10 FASAN0:
g So at this ;oint, it appears that there was a fluffing action g ing n be' ore you got there, and water got into the service air line.
12, Now how could water get into the service air line?
3 14y WEAVER:
I thought we just stated that.
16 CRESWELL:
He mentioned a leaking check-valve.
18 FASAN02 Yes, but that's in the air line.
When they were doing the fluffing the water coming into the; it's one of the vessels that you are going to...
20l l
Well is there a pressure difference between the air and the water?
22 WEAVER:
Yes.
160 lbs water compared to 115 lbs service air.
23 24 C' "' Q [] ] /
251 i
f I
17 1
FASANO:
Then there had to be another valve opened at this point?
2 3
WEAVER:
Yes.
4 FASANO:
Do you know what valve that would be and where it would be?
5 l 6
7 WEAVER-No.
8 FASAN0:
This would be an operations evolution?
g 10 11.
WEAVER:
I'm r.at sure of their operations, of all the valves, the lineup to transfer to high pressure water to remove resins.
So I'm not qualified to 12 speak on that.
14 FASANO:
That's okay.
Okay, then, as far as the logic for the tripping of 15, the condensate pumps and the boostcr pumps, is it within your expertise to 16 talk of that?
18 i
WEAVER:
Not at this time because I haven't sat back to look at them, I 19j would just be guessing.
i 20' 21 FASANO:
Okay.
23 CRESWELL:
On your way down to the polisher panel, did you stop anywhere else and check anything?
2s-
""O 018
{
18 1-WEAVER:
No.
2 3
CRESWELL:
On your way back from the polisher panels or from the receiver 4
drain tank, did you stop anywhere else?
5 WEAVER:
Ther6's nothing really along the way that related to the incident 6
to check.
7 8
CRESWELL:
Did you check anything else?
g 10 WEAVER:
No.
12 CRESWELL:
Then you went on back to the control room?
14, WEAVER:
Yes.
15 16 CRESWELL:
And what happens next.
How many people are in the control room when you get in there?
19 WEAVER:
Now you have more people.
That's when Ivan Porter came and we talked about, I guess while I was down there, he was looking over a lot of 21 the instrumentation and he had some questions on some of the readings.
22 23 CRESil ELL:
What questions did he have?
g 25 l
I I
19 1}
WEAVER:
Some of the in-core thermocouples weren't looking exact:y what he L
2:
expected, on '_,.e computer itself.
The T was high and we questioned that.
H 3
4 CRESWELL:
So what did you do next?
5 6
WEAVER:
Je went down and put a thermocouple breeder on some of the ques-7 tionable in-cores and took some readings to see if they agreed to tne values.
8 9
CRESWELL:
What did you find on doing that?
10
1.1 WEAVER
I wasn't directly involved.
Bob Gilbert and Skip Bennett, 2 other 12 13 f reman, came in by that time and they went down there and took the readings
~
and I believed they reported them to Ivan which he already testified that he already had those readings.
l 16 CRESWELL:
What are you doing in your spare time?
18l WEAVER:
I think I had a couple of things going on.
Item 1, we were getting 19l a couple of technicians to read the RTD, one of theT RTDs to see if we can H
get a on-scale reading compared to, see where T was compared to TC and H
various things like that.
So we connected up a fluke DVM, and 23 CRESWELL:
The DVM is the digital volt meter?
"O 020 2s
f 20 1
WEAVER:
Digital volt meter with a resistance capacity, where if it was 2
accurate enough at the time to see where you were, where we just cross 3
reference that to a curve; and at the same time, my supervisor Dick Siglett 4
came in and we discussed what was going on and we talked, not realizing the 5
extent of how bad it was going to take, we just discussed the workload for 6
the aest of the day and things like that.
7 FASANO:
What time did Sigletts come in?
8 9
WEAVER:
He was there.
I can't say when he came in, but I saw him around 10 11 7:00; but he was called out like myself.
He went and did his own area.
12 CRESWELL:
Did all of what you have told us sc far occur before the site 13 emergency was declared?
l 15j WEAVER:
I can't say.
I heard a site emergency occurred someplace around 7:00-7:10, :nd right about then is when things starting getting... As matter of fact, I probably talked to Dick between 6:00 and 7:00.
I know it 8
was before a site emergency was declared.
g 20 CRESWELL:
Dick?
"O 021 22 WEAVER:
Sigletts.
24 25
21 1
CRESWELL:
What did you discuss with him?
2 3
WEAVER:
We just, like I say, he's the Unit II supervisor of all main-4 tenance.
We discussed the shutdown and the workload for the day.
At that 5
time, it just looked like normal. outage.
6 7
FASANO:
Then you reported to Sigletts when you first came in?
8 WEAVER:
No I was there before him.
g 10 FASANO:
Who did you report to?
11 12 13 14 i FASANO:
And at what time was that wnen you got into the control room?
15 f
16' WEAVER:
I would be guessing, but sometime between 5:30 and twenty of 6:00.
18 CRESWELL:
What's the next thing that you recall happening?
20 WEAVER:
Okay.
At that time, since the other foremen were there, I let them go off and worry about the thermocouple readings and worry about the T readings, and I just tried to organize my daylight people coming on the H
Island and get them into--there's an office right off the control room-get 24 maintenance people available for the jobs that were coming up.
I called 25
"^0 022 1
22 1
over to Unit 1 and had all the Unit 1 I&C technicians sent over to Unit 2, 2.
or they were sent over on their own, I can't remember which.
Basically, we 3
just started organizing the personnel there to stand by and get ready for 4
anything that might occur.
5 :
CRESWELL:
Okay.
You made these calls to the I&C people in Unit 1, or they i
7 had already come over?
8 WEAVER:
Already came over.
They were there in the room and I told them to g
wait in the room until we gave them directions what to do.

They were in standby.

CRESWELL:
What part of the control room were they in?
16' 17 WEAVER:
They were in a room to the side.
It's where the HP people are right now, 9resently using for an office.

CRESWELL:
Okay.
They are on =.andby, ycu're in the control roor.t, what's 2
going on in the control room at this point?
31 4-WEAVER:
That's when Gary and the other people I guess declared a site 5
emergency and they tcok control of all the evolutions.
About that time, is 6
when they set up the, mustering in tim emergency repair parties and people 7
getting the TLDs and masks, and basically everybody mustering that wasn't 8
inv lved in the site emergency.
9 CPESWELL:
Okay.
Are you a member of the Emergency Repair Team?
10 11' WEAVER:
g Normally the Emergency Repair Team is the shift people themselves, but since I feel more qualified in Unit 2 I stayed and the other people...,
13 I stayed as the I&C foreman representative.
g I
15i CRESWELL:
Okay.
But who were you reporting to at this point?
16 17 WEAVER:
1.t this time, there was a period of time when Dick Sigletts was originally there with us and then Dan Shetland came in and took control as the repair party senior man.
It was either Dick Sigletts or Dan Shetland.
21, CRESWELL:
What direction did you receive from either of these two people?
22 23 WEAVER:
We stood by the control room wait:.ig for a job and then after everybody was alerted to don their face, their particulate masks, we went 25 on the turbine floor right outside the door to standby.

CRESWELL:
What happens then?
6:
7 WEAVER:
About that time, I know it was Dan in charge at that time, and he 8
told us to go stand by Emergency ECS, which is over in the HP area of Unit 1.
We all went over there and we stood by there waiting for a dispatch g
n ur j bs.
10 11 FASANO:
2 Did you get involved or did you hear about any problems with the hot well level indication?
13 14 WEAVER:
The pause is because I do remember something but I can't remember 15 exactly the problem.
I can't remember if it was COV59.
There was a valve 16 down there that they couldn't get opened and I told one of my I&C guys to down and see what they could do.
They found, I believe, a pressure sw.'ch 8
full of water and they jumped it out to get the valve opened.
g 20 FASAN0:
COV59?
21 22 WEAVER:
Don't quote me about that.
There was a valve they needed opened and it had to do with a pressure switch which was full of water and they 24 jumped the pressure switch out to get it opened.

get the numcering right.

Okay.
So you sent someone down to jumper your indcation so tF st 7
the valve could be then opened?
8 g
WEAVE 1 Yes, sir.
10 FASANO:
g Alright now, do you, just jumping back a bit maybe before March 28, g
do ycu recall wi..re the atmospheric dump valve bellows ruptured, got steam g
into the room I guess Miere some of the emergency feedwater, cabling gear and motors exist?
I 15 WEAVER:
Yes.
I remember it well.
I 17' FASANO:
You do.
Was, did you know about the checks made on the connections and the motors, are you involved?
20 WEAVER:
Not on the motors themselves, no.
22 FASANO:
Who would have done that?

That would be electrical department and construction.
They were 1

4 FASANO:
Did you get involved in any of the checkout after that steam 5
released?
6 7
WEAVER:
We were involved in the all the instrumentation and all the cabling g
that had to do with instrumentation.
We recalibrated all the instruments g
that were in that room, functional checked them, did continuity checks, gr und checks on the cables that had to do with instrumentation.
10 11 FASAN0:
How long ago was this?
Do you recall the date?

No, I don' t but that's available.
It's on record.

Yes.
I forgot about that.

l
27 WEAVER:
I would probably say between 8:00 and 8:30.
1, 2.,
3 CRESWELL:
Why did you make the entrance?
4 5
WEAVER:
Operations lost all ventilation in the aux building and they 6
wanted the ventilation back on and it had to do with a spurious alarm on 7
the fire detection system.
The detectors are sensitive to moisture or just 8
particulate, and I want in to bypass a fire defeat switch to allow the fans g
to start.
10 CRESWELL:
What floor is this defeat switch located?
11 12 WEAVER:

Can I back up for a moment.
Let's go back to you in the control l
2' room with the declaration of the site emergency.
Oc you recall who made 3
that declaration or how you became awara of it?
4, WEAVER:
No, I don't.
The announcement was made and I'm not sure who 5
6 spoke.
7 00NALDSON:
What is your normal response to the declaration of a site 8l g
energency?
10 WEAVER:
We have a control point to muster at, back where the emergency repair party..
13 00NALOSON:

And where would that be?
I 15!
WEAVER:
For Unit 2, it would be the roll up doors by the turbine building.

The roll up doors by the turbine building?
That would be the 18J l
ground floor?
19!
20 WEAVER:
Yes, sir.

According to the response plan, the repair party would muster 23 in the emergency control station.

3 DONALDSON:
You were not simply because you were not shift maintenance, is 4{
that correct?
5 ;
WEA'.'FR :
That's right.
6 7
DONALDSON:
So you formed a secondary group of people in the control room.
8 9
WEAVER:
Yes.
10 11 DONALDSON:
I think you did indicate that a repair party did form?
13 WEAVER:
There was a repair party formed over in the normal ECS.
But we 15l formed in the control room with my Unit 2 people who are aware of Unit 2.
They have the expertise in Unit 2.
That's the people that stayed with me in this incident.
We did not muster down at the roll up door because I needed those people for Unit 2 problems as they came up.
19 DONALDSON:
In other words, you intent was that the Unit 2 people you would keep as repair party people but keep them in the control room and not at r
21l the control point where
...?
22 23 WEAVER:
We were not in the control room.
We were at the room to the side 24 and word was put out that I was going to keep my people here because I feel 25 our people are qualified technicians to respond to the emergencies.

DONALDSON:
Are the shift people not qualified?
2}
3 WEAVER:
I didn't say that.
4 5
DONALDSON:
Clarify than what you mean by your people are qualified.
6 WEAVER:
7 What I'm saying is Unit 2 daylight workers I work with constantly 8
and they are more aware of my Unit 2 for ease of getting around.
It is just familiarity.
And when I say we had Unit 2 shift people and Unit 2 g
10 d ylight people and the shift people must go over there.
I kept my daylight people there because they have expertise in systems that shift people don't have.
13 DONALDSON:
Are there provisions for mustering the unit specific people in the control room as opposed to the check point?
Forming two repair party 15I teams.
16 17 WEAVER:
No, I don't think there is 19 DONALDSON:
Then early after the declaration of the site emergency, we 20 really have essentially two repair party tea:ns formed, and one in the 21 normal ECS and you with your group of site specific people in the room off 22 to the side of the co'itrol room?
Is that right?
23 24 25

Yes.
We mustered and the names were called down to Security and 2
the people were accounted for.

I 6l WEAVER:
Normal dispatch calls from the ECS over at Unit 1.

I believe by the emergency plan a shift maintenance g
10 f reman can be the head of the repair party.
Is that correct?

Let's go back to after you had your people formed.
I 11, believe you said you were taking directions from some of the shift operations pe ple.
Dick Siglett took over and eventually Mr. Shawes showed up.

Mm Mm 15j 16 DONALDSON:
Can we try to go through and lets just take the morning up until about noon, if we can.
Now let's try to piece together the various 18l.
repair or corrective actions that your group of people might have performed 19 that morning.
20t 21 WEAVER:
- 0. K.
22 23 DONALDSON:
All right.
I believe you mentioned that your number 1 function 24J l
that you performed, or one of the functions, was you made an entry into the 25{

auxiliary building to pass the fire defeat switch.
And you mentioned that 2t you weren't sure who directed it but it was one of the shift operations 3
people.
4 5
WEAVER:
Not thought.
It would have been.
We don't take direction from 6
anybody.
It's a shift supervisor or his direct supervision.
7.
DONALDSON:

Again, I've got to go back to the normal emergency organi-g g
zation that you drilled and practiced in the past.
If you were located in the Et,a, how would you get that direct.

It would come through the supervisor of maintenance who would be g.
at the ECS and say go do this.

contro' room.
I wo-. not go into an aux building that know that is contam-6 inated without any type of forethought.
I sat and I talked with peogde 7
before I do anything and I just can't remember who I walked to.

You were requested to do this.
Were you asned to volunteer g
f r it or were you just directed to do it?
10 11 WEAVER:
They directed somebody ter emergency repair party to do it.
I volunteered to do it because I feel I am probably more qualified in that area because I do have nuclear background.

At time we will change the tape.
It is now 1:37 p.m.,
Eastern Daylight Time.

This is a continu-19 20 ation of the interview with Mr. Douglas Earl Weaver.
21 DONALDSON:
0.K. Doug, we were talking about your first trip into the 22 auxiliary building and you mentioned that you thought that you were briefed 23 by one of the health physics staff.
I assume the briefing took place in 24 the control room before you departed?
(T ^ Jr 038
38 WEAVER:
This whole period of ti'me I had, I talked with Dick Dubiel on various, just general information on what was happening, where the radiation levels, just for my own information, just to keep posted, so if something did happen I would have an idea what was going on.
They requested that somebody makes an entry into the aux building to jumper out the switch.
I wanted to go myself, mainly because I feel I have a lot of experience in radiation and I was familiar with the aux building and I knew where the 7
switch was and I would rather I went in myself than a person maybe not as 8
experienced, with maybe just 6 years of nuclear training in other areas.
9 10 DONALDSON:
- 0. K.
Now in your discussion, and maybe you can't pin it down ll, this specific thing, but do you recall whether or not generally you were 12 aware of the dose rates and the radiological hazards in the area where you 13 were going?
14 l
15i WEAVER:
We have...
No.
0.K, I remember doing things now that you just 16i sparked the whole thing.
We went back and we tried to get a feel for 17 radiation level.
That's right, Dick and me did go back and we reviewed the 18l area monitor panels, looking for the type of readings we could expect from 3
19l j
the Victoreen monitors.
There is a monitor over in the one corner of the 20l aux building and that was one of the things we based our dose rates on, to 21 see what we could expect.
But the whole time I went in I had a dose rate 22 meter with me and I had a teletector which I was monitoring the whole time 23 I was in there.

So prior to entering the auxiliary building you checked 4
2,I the area monitor panel and as best you could tried to ascertain what the 3,
new levels were? 0.K.
Did Mr. Dubiel and yourself determine what protective 4
clothing you should wear?
51 6
WEAVER:
I can't say it was Dick or who, but out of the whole thing we knew 7
how we had to dress, Scott airpack, and protective clothing and how to...
where our control point was and everything like that.

WEAVER:
Yes.
2 3
DONALDSON:
Now I believe you said later that in that morning that you did 4,
marry up with the group that was downstairs at the ECS.
5 6
WEAVER:
Then the whole repair party merged together at the Unit 1 ECS and 7
at that time, because when they, around 12 o' clock is when they wanted to 8
minimize the people on the Island.
And I and two technicians left the g
Island and Barry Kalenevitch, which is another I&C foreman, shift type, he 10 stayed on the... as ow the only repair supervisor onsite.
11 DONALDSON:

Now you mentioned that you married up at the Unit 1 ECS.
That would be back down at the Unit 1 he'llth physics and chemistry check 13 points.
g i
15j WEAVER:
Yes.
17 DONALDSON:
Did this marrying up occur before or after the ECS evacuated 18f l
from the Unit I check point to the Unit 2 control room?
Let me put it this 19l way.
When the two parties married up, were there only maintenance and repair people in the area or was the ECS still activated?

In Unit l?

Now, in Unit 1, you're not talking about.
Was it in the 6
Unit 1 control room or in the Unit 1 HP and chem checkpoint.
7 8
WEAVER:
I'm not sure where they really had the official ECS set up as far gj as the management position, because they had tha communications channels 10 set up between Unit 1, Unit 2 and the HP area.
I'm not sure which was the 11' actual " turn all" to ECS.
That would be up to the people running it.
12 We were just reporting to that area as a central location for all maintenance pe ple to report from.

So in the morning then, eventually all the maintenance 15 made it dcwn to the HC chem area.

Now to help you out a little bit.
Maybe it will jog your memory.
The Unit I chem HP area was evacuated, I think approximately 8:45 9:00 in that area sometime, and they moved the ECS to the Unit 2 control Did you see when your team was down there, did you see Mr. Mulleavy room.

Did you remain in 5
that area for the rest of the morning?
6 WEAVER:
We remained there until around 12:30, when they told the rest of 7
g us to go offsite and leave a skeleton crew.

So for the better part of the morning after you made your 10 entry into the auxiliary building you remained at the Unit I chem HP check 3
point?

And you continued to see the ECS in operation at that location?
17 WEAVER:
ISj Yes.

DONALDSON:
And you left the Island?

21 WEAVER:
I'm not sure if it was called the ECS.
They can move the ECS at i
22l their discretion but there was people manning that location.

DONALDSON:
Good.
And you went to the observation center.
6 7
8 9
NALDSON:
What functions did you perform over there?
10 11 WEAVER:
Just basically stand by for any questions that might be needed from my area and assist in any other matters, labor, anything that had to be done.
15j l
DONALDSON:
Did you remain there then for the rest of your shift?
16i 17 WEAVER:
I remained there until 4:30, 5:00 that day, yes.

Then the following day, which would be the 29th, did you 20 report on the Island or back to the observation center?
21 22l WEAVER:
I raported to the observation center first and then I went on the 23 Island.
24 25 I

47 1
DONALDSON:
And where did you report when you went on the Island?
2 3
WEAVER 2 The Unit 2 control room.
4 5
DONALDSON:
And to whom did you report?
6 WEAVER:
I...
There were so many people there I can't single out one 7
8 person Jim Logan was there, and I'm not sure if Gary was still there.
g This senior " management personnel" there, I would have reported to, to keep them' aware of where I was.
0 11 DONALDSON:
- 0. K.
Then on the second day when you did report back to the Island? Were you at that time the senior maintenance supervisor?
14 l
WEAVER:
I don't think so.
15 16 DONALDSON:
You don't think so?
17 18f WEAVER:
I think at the time the company sent up a senior management person controlling maintenance functions from the observation center and Barry Riddle, I believe was there and myself.
I think Barry was designated the 21 senior maintenance foreman, supervisor, whatever you want to call it.
22 23 00NALDSON:
Barry Riddle, is he the electrical foreman?

WEAVER:
Electrical foreman.

3t DONALDSON:
- 0. K.
You mentioned that you thought that the observation 4
center had picked up.
S 6
WEAVER:
I knew that they had on shift at that time senior maintenance 7
supervisors controlling maintenance functions from the observation center.
8 g
DONALDSON:
- 0. K.
By senior supervisors, would that be the supervisor of 10 maintenance and superintendent of maintenance, or would it be GPU people?
11' WEAVER:
g No, to be exact it was Dick Sieglitz who is the Unit 2 supervisor j
of maintenance, Tom Hawkins which is the Unit 1 supervisor of maintenance, Pete Snyder which is the I&C department supervisor and John McGarry which g
is the mechanical station supervisor.
16!
DONALDSON:
- 0. K.
So maintenance then from the second day, repair functions, so on, are being controlled from the observation center?
19 WEAVER:
Yes.
20 21 DONALDSON:
Car. you recall for me any functions or any entries that your people made to perform any kinds of manipulations or functions on the 23 second day?

49 1
WEAVER:
I should have my...
To give exact days and times I would need my 2.
log to state everything that we might have done because we did too much in 3
each day, we didn't do too much, I mean we did various evolutions and I 4
can't single out one day from the other as far as which I did when.
S 6
DONALDSON:
In general, were the entries in the various areas being coordi-7 nated with Dick Dubiel or someone else?
8 WEAVER:
Yes.
Dick was an active member in the control room when I was g
10, there. He was very active because I know, I did go in the aux building that 11-day I believe, to run a hose for venting one of the various tanks they 2l needed vented and at that time Dick was actively involved with directing A
he H coordination unit.
13 14; DONALDSON:

Do you recall where the hose was run from and where it 5
went?

17 WEAVER:
Yes, I do.
181 19' DONALDSON:
Would you tell me, please?
21; WEAVER:
We went from 1485, I believe it is.
The number... it's basically is the first, is the RMS monitor in the first room in the aux building corridor, I believe it is 1485, I could be wrong, it could be 1486.
We ran 24 it from there over to a pres 3ure switch to relieve pressure from, I think it was the bleed tanks, to the reactor building.

From the bleed tanks into the containment?

WEAVER:
Yes.
7 8
DONALDSON:
Again, same basic question.
Did you have health physics coverage g
with you?
10 11 WEAVER:
We had at the time one technician, myself, one man outside standing by no HP man with me as such, but at the time they had surveys, plus we used existing radiation monitors to see what levels we were at and we carried HP equipment with us.
I 16l DONALDSON:
- 0. K.
Do you recall what the levels were in that "ea?
18f WEAVER:
I would be able to get close enough as far as the area we were 19l working, I think we're talking a couple of hundred mR.

DONALDSON:
Was anyone writing RWP's or did you have specified dose limits?
4-Did anyone tell you what the maximum exposure?
5 6
WEAVER:
Yes.
7 8
DONALDSON:
What was the administrative limit that was set at this particular time?
g 10 WEAVER:
11.
Dick told ne I wasn't allowed t go over 1000.
12 DONALDSON:
Over a thousand millirems?
13 14 5ll WEAVER:
Well, I am going to be very vague on this.
I was given one limit on the first day.
I think I exceeded that by, it was a very conservative limit.
g 18 DONALDSON:
Do you recall what the limit was?
g 20 WEAVER:
It wasn't the first day.
It was the 29th, the second day.
It was 21 a very conservative limit.
It was 100, 150 and I exceeded that by maybe 15.
If I get, if you don't want exact numbers...
I think I can tell you it was 150 and I got something like 165 the first day.
So then I went back in numerous times and they gave me up to 1000 to go in.

DONALDSON:
0.K. A thousand on that entry, or...

WEAVER:
No.
1000 total.
I was to keep track of my total.
4 S ',
DONALDSON:
- 0. K.
So you were instructed to keep track of your own total 3,
cumulative dose?
7 WEAVER:
olus we were, at the end of the day we had to go to the observation g
g center and report our lev:ls to the observation center where they kept the record.
10 11 DONALDSONi So you would keep your own record of your exposure?
13 WEAVEM I believe the first day, that's what we did, yes.
15{
DONALDSON:
And then the end of the day you would report to the observation center and in turn report to them what your exposure for the day was?
18\\
l WEAVER:
I believe the first day that's the way we handled it.
19{
20 DONALDSON:
The first day, 0.K.
What did you base this on?
The number.;
that you had.
22 23 WEAVER:
My dosimeter.

numbers that they had on their dosimeters?

Now we're getting into an area...
One day I didn't believe my 4;
5 reading and they read my TLD immediately.
They were verified that way.
6 When you had questions of what you had it was immediate readings or if you 7
exceeded your limit, they read your TLD.

DONALDSON:

So you did have an administrative limit for that second 14l i
day's entry? Like you Jaid, you had about three or four people working on that job with you?
i 16i 17 WEAVER:
I actually had one technician that went inside with me, and I had a man standing by in case that we exceeded our limits of stay time.
Dick 191 gave us stay time and if we exceeded that we had people... hey, here is what you gotta do, type thing.
21 22 DONALDSON:
Did any one in your party exceed the administrative limit of 23 1000 millirem or exceed stay time?
24
,3;
""O 054 I
l I
54 W AVER:
Not to the best of my knowledge.
I was surprised how quickly...
J 11 l
2' Well, we made a lot of preparations before running the hose and we did all 3
our up, at that day the 29th I moved my shop into that room to support 4,
operations and we had a regular maintenance function set up in that room 5
where I told you most of the people stayed before and we did.. we prefabed, 6
we hydrode and did things like that there ar.d then we just went in and did 7
installation type work.
8 DONALDSON:
g So you tried to preplan your work as much as possible to limit stay times?
10, 11 WEAVER:
Yeah.
We made the fittings up; we hydrede.
You know, all that stuff had to be done before you went in and that's why, my une reason for the 28th of staying, I am more, my daylight people are more familiar with 9
15 with what size tubing do you need to go in this fitting, and are more 16,j involved in little details like that.
That's why we were able to do a lot of our jobs when we knew exactly what type of fittings you're going to be dealing with, more so than a person that, they're as qualified as what we 19l call our daylight people, it is just that they have--their area is more flexible.
So we were aale to plan our work and do the job in the quickest time.
22 23 DONALDSON:
Okay.
On the second day, the 29th, other than this routing of 24 the tubing of the bleed tanks, did you perform any other functions, or were 25 you involved in the planning for any additional entries?
l
55 l
I 1.
WEAVER:
We did other, you have access to my work list.
You've already 2
looked it over.
The NRC did review it, so I assume your notes would probably 3:
have things there that would spur my memory, because right now without my 4
worklog here, I can't give you everything we did.
During that day, the 5
time frame that we are talking about, we did var'ous functior,s outside the 6
controlled area, where we took readings 'or operations, racorded them just 7,
to aid analyzing what was going on.
At this time, B&W and people were g
requesting readings.
9 DONALDSON:
Okay.
For entries inside the controlled areas, would you say 10 g
the same general procedures as you previously S: cussed.
12 WEAVER:
From my department, I know they were all handled that way, mainly becausa ve set up, like I said, a maintenance function right outside the 15l control room to assure that we had a working log to pass on from shift to 1
16l shift.
Also, to have spare parts and organize the 3 tuff and know what you have available.
At this same time, if I'm not mistaken, Unit 1 people I
Ossisted me by working out of Unit 1, and by phone call, say, " Hey, I need 18!
l 500 ft of tubing.
Could you get it for me?"
and they would transport it 19!
over.
And keeping that stuff in a central location.
All our I&C jobs were done in that order for those three days, and the other jobs that we were 21 i involved in I know about, I personally went in when I wasn't familiar with 22 it, and scoped out the job, see what fittings I would need, marked off how 23 many feet of hose, you know everything, the hand tools.
Just to assure 24 i
that if anybody got a dose of radiation, it was me who was the supervisor, 25l "O
056 i
56 1
compared to the other people, who didn't have, had to do the work for me.
2 I was able to minimfze, go and do the supervisory work and get my exposure 3
and then to go in and say here's how I want you to do it.
And then, how we 4
eventually worked out a big job when we ran lines and things that are 5
emergency conditions, we would lay it out, have a briefing.
I would go 6
d wn there and I would be completely dressed, and the foreman would be 7
completely dressed, say here's what I want you to do.
We'd go in there g]
show the guys--we want you to run from here to here--and they would see a
gf everything.
And then the supervisor would come out and go in on a periodic 10 thing or stay there to support them with anything else they'd need.
To g
send people in and out, when'you see their air tarks running out, you send g
another person in to continue the job.
I 13lh DONALDSON:
Okay.
You mention that those were the procedures that you f 11 wed with 1&C crew.
Were there parallel crews working with other kinds 15 i
of maintenance?
g 17l 1
WEAVER:
There was a mechanical department that was doing a job with me; we 18, 1
were running another line, and they basically operated in the same format I 191 I
did.
20 21 DONALDSON:
Okay, in addition, were the mechanical department people, and electrical and so on and so forth, running their own specific functions at this time also?
24
'"O 057 25 I
i
57 1
WEAVER:
The mechanic,... the I&C Department is the only people, that send I
gj a crew of people onsite to be ready and available.
The mechanics and 3
electricians were dispatched as jobs came up.
4 5
CONALDSON:
Okay, so the I&C essentially had the lead for repair party 6
functions?
7 WEAVER:
The I&C didn't have the lead, but the I&C is involved in things 8
g that are not repair party type jobs, where you need a person to take a 10, ltage reading for people that are analyzing what's going on for instrumen-y tation.
11 Mechanics and electricians, they're more of repair type things, the motor doesn't work and you got come in and replace the motor.
But a person will come to me, I need a recorder, a heater; I need a voltage 13 reading over here; I need something looked at.
You need peop h available p
to support instantaneous type jobs.
15 16' DONALDSON:
Then you say you perceive yourself to be more or less a repair party support team?
i 19 WEAVER:
I'm no' sure.
Maybe you don't understand what I'm trying to say or maybe I'm not understanding.
We're not only a repair party; we were there also to help the people that had to collect information-- that used digital volt meters--things the engineering staff needs.
There was, at this time, supervisions here, engineering people here that needed information, say, " hey, what's going on?
Could you take readings for us?"
You can't 25 o^0 058 I
58 1
call over to the observation center and say, we need a volt meter reading 2
here, or how does this work? You need a person there that can answer those 3
questions.
4 DONALDSON:
So you were sort of like advisory to a number of people?
5 6
WEAVER:
We assisted a number of people.
7 8
DONALDSON:
g And then, when necessary, you actually performed repair party un ns?
10 11 WEAVER:
When necessary, we performed them.
13 DONALDSON:
Okay.
That makes it clear.
Before I drop back and talk. tout something beforehand, do you want to discuss Tony, any specific work items?
16' FASANO:
Well, yeah, I liked to maybe get some background information.
Are 171 you familiar with the dipping bird?
18l 19 WEAVER:
(laughter)
Sure.
20 21 FASANO:
What is the dipping bird?
22 23 WEAVER:
It's a highly technical name for the C0 leak-off on the RC pumps.
24 25
""O 059 I

59 1
FASANO:
Okay.
Was there a problem with these prior to March 28th, do you 2
know?
3 4
WEAVER:
Such as.
5 FASANO:
For, well, so that one could evaluate the actual inventory of 6
7 leakage say from the primary system.
Was information available so that one 8
could make a determination to the inventory leakage in the control of g
environment of the reactor building.
10 WEAVER:
I would have to go back and look at my worklog.
But I know on one of my outage items, one of the birds were actually stuck in the dip position, and all the other three were functional.
14; FASAN0:
Based on your experience, what can cause one of these mechanisms to stick in the down position?
16}
17 WEAVER:
It's a very simple mechanical type device and just normal type of the environment that it's in, could cause a little bit of rust on the pivot points.
The way the unit is set up, you tighten down on the pivot points until it dips freely and accurately, and any type of, well I shouldn't say 21 dust, but moisture content or anything could just cause it to set up balance 22 type system, throw it out of balance.
23 "O 060 24 25 1
60 1
FASANO:
In the down position then, you could have leak 2qe and it just 2
would fall out and you don't record it.
3 4
WEAVER:
(indicates yes) l 5
FASAN0:
Would anyone be able to estimate an error or have anyway of knowing 6
7 what leakage is coming off on that particular...
8 WEAVER:
g Not from the dipping bird, itself, but I'm sure B&W people have a better feel of that area than I do.
10 11 FASANO:
How about the electromatic relief valve? Are you familiar with that piece of equipment and do you get involved in evaluating the circuitry 3
or the readout in particular?
l 15i
.j WEAVER:
I'm familiar with it and I probably should be more familiar with it than I am, because our department handles the indication and I'm familiar
,7 1
with the circuit but I didn't get involved in any of the repairs on it, so I can't comment too much on it.
19 20 FASANO:
Were you involved in the modification, where the I guess the logic was changed and also the indication light was rerouted to give a specific indication as the power goes through the solenoid?

The time now is 3:llp.m. and our interviewee is back.
22 FASAN0:
What I would like to know is--there's a leak on the electromatic 23 valve ad also on the code safety valves.
Is there a way of really deter-mining remotely separation between the three valves, and do you get involved 25 in this area?
" O 062 l
62 1
WEAVER:
We have a temperature detector on the pipes themselves, which will 2
tell you pipe temperature, which will tell you excess leakage just due to 3
heating.
4 FASANO:
5 Can you tell frv, can you really tell which one is the predominant leaker?
6 7
WEAVER:
I would not be able to comment on that.
8 9

Have you ever looked at it?
10 11{
WEAVER:
No.
13 FASAN0:
Okay.
Who would be the people or person that really knows...

WEAVER:
I would just have to guess when you have a leak light, if you feel you have a leak, you have somebody from engineering or somebody from opera-tions looking at that.

If they were concerned, if something wasn't right, the question of 4
calibration or the reliability of something, they might ask me my opinion.
5 Okay.
I guess there is only one other question.
Did you...say 6

y u had left by about 12:00, I gather?

Not myself, no.

DONALDSON:
Okay.
Now going back... you say 3 ou trentioned site drills.
I 10 wonder if you could kind of compare and contrast the way that the repair g
party function went during the actual event with the way you'd run it or the way it was conducted during drills.
Would you say it was the same or it was different?
If it was different, how different?
I 15l WEAVER:
I would say that the actual emergency was, well, it's hard to say, because when you have a drill you always have a time frame that you want to get the drill done with and you go and you say you iave a leak here, and I
they send you in the aux building to repair a leak, and everything is 19[
'always in abbreviated form.
Now, I would say we did everything on emergency i
20' type procedure, but it wasn't the abbreviation, where during the drill, you will sit down, you would simulate briefing the people, how you would do it.
22 During the eme'.gency we actually sta down and talked about the job.
We 23 actually did the testing and the things like that.
We planned our mainten-24 ance before we went in and did our work.
So, if you would take a drill and 25
""O 068 t
68 l'
drag a drill out for a 10-12 hr period and show everything that you would 2
have to contend with, I would say we did it the same as the training that 3
we had.
But, you can't correlate them because a drill is a drill and this 4
was action.

DONALDSON:
Well, I don't think I have any more questions.
Tony, do you 7
have any?
8 FASANO:
One quick one.
I found this in their FSAR.
I wondered if we do g
indeed have thermocouples in here.
This is called a vent valve thermocouple 10 11 n zzle.... it would be interesting, you know, you were here during the preop I guess, and if indeed there was a thermocouple.
12 13 WEAVER:
I was here from preop, but I never looked at that.
l 15' FASANO:
It would be interesting if we really had one in there, it would be 16 },
in a good lccation, but apparently you don't have any knowledge of that?
18i WEAVER:
No, I don't.
20j FASANO:
Okay.
22l WEAVER:
One thing, during the middle of this interview, I sort of, you know, I lot of questions were asked that made us look like we didn't give any forethought on some of the things.
I want to put on record that things I
" O 069 9
i, i
69 l'
we did, and when we went into areas, even though I myself can't remember 2
all the people we spoke with, but there was a lot of conversation going on 3
back and forth between all the people involved and before we actually did a 4-function, and especially defeating that switch and talking about going in 5
and taking the radiation levels.
People there, we did look at a lot of 6
tnings, and even though the names can't be recalled, a lot of conversation 7
was going back and forth even though it wasn't on record where I felt 8
assured when I went into that building I knew what I was 'to expect and and g
how they were going to handle the situation.
10 RESNER:
Okay, duly noted.
If you gentlemen have no further questions, I 11 y
wonder if for the record, Mr. Weaver, if you have any recommendations or observations specific to your area that you want to share with us?
14 en ng say in Ws Meniew.
15 16l RESNER:
