Thank you very much Mr. Spangler and now I$11 turn the interview,over to Mr. Creswell.

8 CRESWELL:
Jim Creswell speaking.
Bill, I wonder if you could back to If the day of March 28, 1979 and relate to us when you first found out 10!
about the event at THI-2 and how you found out about it.
11l 12l SPANGLER:
I found "out about it by way of telephone call from Lee I
13 Rogers at very close to 7:45 a.m. March 28.
It was exactly the time I 14 arrived at the office that morning.
The phone was ringing, as a matter 151 of fact, when I hit tne office.
That's when I learned about TMI.
1 16t 17 CRESWELL:
What did Mr. Rogers relate to y. u about the event?
18l 19I,.
SPANGLER:
Lee got me on the phone and I don't remember his exact words l
20!
but he said something to the effect that we've had, we had a serious l
l 211 situation at Three Mile Island and he relayed to me the following 22 information. He told us that the incident started at approximately 4:00 23 a.m., it was on TMI-2, they had a loss of feedwater while operating at l
24 98%, the turbine tripped followed by reactor trip.

They believed 2!
l the quench tank rupture disc broke.
They sere registering or had registered 800 R per hour in the dome at some point, I don't'know when.

That's about it.
He did mention 'that a fuel leak was a good possibility.
5 Gi I
CRESWELL:
Fuel leak or fuel damage.
j 7I 0
SPANGLER:
Fuel leak.
9f CRESWELL:
Okay. What did you then do with this information?
ui 12 SPANGLER: Well first of all, when the telephone came in, as soon as 13 Lee mentioned it was a serious situation, I called two additional people in my office.
One was ' Ken Wandoing, who is my assistant, basically.
15I
)
16l CRESWELL:
Excuse me Lee could you could spell his last name.
17l 18i SPANGLER: Wandoing.
I 19 l
20 CRESWELL:
Wandoing, Ken Wandoing.
l 21 22 SPANGLER:
Ken Wandoing.
And the other gentleman was Don Hallman.

l CRESWELL:
Okay.
Si I
7l SPANGLER:
Hallman is the Manager of Plant Performance Service.
Its a service organization.
So these two gentlemen heard all this information.

I l
~i Lee was on the squawk box in my office.
10!
l f
11 CRESWELL:
They heard the call also.
12l 13 SPANGLER:
They heard the call also, that is correct.
As a matter of 14!
fact, the notes I am using were notes taken by Ken Wandoing.
He was 15 designated by me as the offidial note taker of telephone calls that
}
16!
day.
So the question then was what did we do following the phone call.
17 IS{
CRESWELL:
Right.
191 i
20 SPANGLER:
Okay.
The phone lasted just a very few minutes, long enough 21 to relay this information and my next move was to, well first of all we 22 recorded the information that I gave you on the board in my office and c
23 my next move was to call Don Roy.
Don Roy is Manager of Engineering 24-25 i

Don then made arrangements 2l l
to set up a task force and identified Bruce Karrasch as to lead such a 3r I
tast force.

CRESWELL:
Could y'ou spell Mr. Karrasch's name.

I think it's Karrasch.
Bruce Karrasch.

CRESWELL:
All right.
Do you know what his title is.

task force.

g 16l SPANGLER:
Yes.
And we set up a meeting for 9:00, 0900, in Classroom B L17!
to make this information that we had known.
i lal f
19I CRESWELL:
Bill, Classroom B is close to the simulator.
20 21{
SPANGLER: Classroom B is right down next to the simulator.
So at 0900 22 we then had the meeting.
Do you want me to go on?

51 CRESWELL:
Just st'ep through the sequence.

SpANGLER:
All right.
0900 then, we had our meeting which was attended 8{
by a number of people including Don Roy, Alan Womack, Bruce Karrasch, Don Hallman, Ken Wandoing and many others.
I guess there were probably 10 20 people in that room.
And at that meeting we relayed the information 11f 1
Lee had given to us on the telephone to this group.
At that meeting we U
also identified a specific list of information that we would like to 13
-- get from the site when they called back.
I have that list right here.
14:
15 CRESWELL:
Could you identifywhat those items are?
16' 17 SpANGLER:
Yea, the information specifically requested were... requested 18l the information was identified at this meeting to be useful to us in 19 Lynchburg was pressurizer level, steam generator levels and was it 20 controllable, the reactor coolant pump condition, did the Aux feedwater 21 actuate, secondary side temperature / pressure, RCS temperature / pressure, 22

~l CRESWELL:
Excuse me just a minute.
You stated in item 3 that you Gi would want to know about reactor coolant pump conditions and the last 7l item that you talked about was the pump trip.
Could you go back to
- i

that item that referred to the pump trip and read it again please.

SPANGLER:
Chronology of sequence of events, pump trip, when - why.

I would assume that means the r. actor coolant pump.

So you had knowledge that the RCPs had...any reactor coolant 17f pump had been tripped.

Yep. We got that in the initial phone call.

f CRESWELL: How long do you estimate the 9 o' clock meeting lasted?
5\\
i SPANGLER:
I would guess, looking back, half hour, 45 minutes.
7!
at CRESWELL: Was there any discussion of fuel damage during your 9 o' clock meeting.
10; i
11 SPANGLER:
No, none other than, you know, the correlations between the im activity levels reported in the building and there's an obvious pos-A bility based on that there is some fuel damage.
14!
13 CRESWELL:
There was a correlition of activity levels in containment.
2 15i 17l SPANGLER: Well I made that in my own mind, and I am assuming other i
13]
people did.
There was no specific lengthy discussion about that, fuel 19) damage.
Really, the conversation during that meeting was directed at 20) letting people know that tne incident had occurred, getting a task 21 force of people thinking about the thing, identifying the kinds of 22 information that we would like to get. Now that's the last activities 23 specifically recorded here until 10:30.

SPANGLER:
Didn't...at the time.
I don't recall thinking of it in 2'

If I could sit back now and reflect I'd probably 3
say "yes, its not unreasonable."
4!
51 SPANGLER: OK. Want me to go on?
j 63 I
CRESWELL: Go ahead.
SI CRESWELL:
Let me understand one thing. You haa received no communications l0 from Lee or Greg Schaedel up until, or between the time of 7:45 until 11l 10:30.
12!
13' SPANGLER: That's right. That's the next recorced thin,g in these notes 14!
is that at 11:45 we had a telecon with Schaedel who was apparently at 15 his residence.
16i 17 CRESWELL:
Greg called you?
18(
19 SPANGLER:
Greg called me at my office and identified that he had just 20 finished speaking to Lee at the site and had some additional information 21 concerning the transient and at the end of it it appears that the 22 reactor coolant pump had shut down.
Trying to go solid and, actually I 23 don't know that means, whether the plant was trying to go solid or 24 whether I assumed the plant was trying to go solid, I don't think they

i were trying deliberately to make it solid. Indicating that a steam x'I bubble in the RCS loop, a specific loop was identified.
Low level radioactivity in atmosphere reported, Met Ed had made public announcement 4!

j to the news media.
Radiation teams performing surveys on and off site, l
5
and NRC teams sent to site to investigate.
Primary to secondary leak
.I on B steam generator confirmed by sample analysis.
B OT5G as a result 71 had been isolated. I have no idea what time.
And they wer2 cooling down on A steam generator, feeding the steam there using natural circu-of lation.
At this point he does indicate tnat the HPI is taking suction
~
' 01 from the barated water storage tank. Some indication that. the pressurizar 11!
heaters had shorted out and they were using pressurizer electromatic 12 isolation valves to control pressure.
At this time the RCS conditions 13 were T cold, 300 degrees and the system was 2100 psi and their plans 14l were to cool down and depress'urize.
Speculation of fuel leakage but no 15I further information on radiation levels.
Some level increase in reactor 3
16 building sump.
High moisture level in the reactor building.
Did 17!
mention that component cooling water seal *njection had been maintained I

ISI on the reactor coolant pumps.
At that time I asked Greg to have Lee l
19{
Rogers call up at 1315 so we could establish a time so we could keep
'20 the telephone open.

I 11i 12 SPANGLER: We were then expecting a telephone call from Lee Rogers at 13 1315 and prior to that time in preparation for that phone. call we la established ourselves in the Project Control Center.
At this time the 15!
task force had totally outgro'wn my office and that was when the Project 16!
Control Center, Command Center, Communications Center, was established, t
17 somewhere around one o' clock, one fifteen.
One thirty, 13:30, then we 18l had another telephone call from Schaedel.
And the information being 19 reported to us was that the reactor coolant system was at 495 psi and, f
20 of course, floating on their core flood tank.
T hot was 700 F and this 21 was apparently by volt mater.
Pressurizar was full, and they were 22 controlling pressure with the electromatic relief valve isolation 23 valves. The HPI was taking suction from borated water storage tanks 24 25 Wt sO.

He indicated, and I 15!
don't know that that means his. comment that the minimum coaldown from 2

A0TSG, that was A steam generator, we were still, they thought were i
17 cooling down on those pumps, (unintelligible words).
They were dumping 18j steam to the atmosphere through the atmospheric dump valves because 19l they had lost gland seal steam on the turbine (that's your backup 20 mode).
So they were dumping to the atmosphere at this time. Emergency 21 feedwater to A steam generator through the main feedwater nozzles. No i
22 further information on radiation levels. Airborne activity in the aux 23l building and the controlled area. I don't understand exactly what that 24l meant. He did indicate at that time that the reactor building sump was 25l i
