SHANNON:
I was enlisted in the Navy in 1970, November of 1970 as 10j electronics nuclear operator.
I went through electronics school till 11 the end of 1971 then I went to a Nuclear Power School, Mare Island, 12!
Cal i fornia.
In the beginning of 1972 I went to S3G prototype in New 13 York also in 1972.
Then I was sent to the USS John Marshall nuclear t
14l submarine.
I was there for 3 years serving in the nuclear field reactor 15l operator status.
October, 1976 I started at Met Ed as a Auxiliary 16l Operator and I trained to be a A Operator.
The training lasted ap-17l proximately 6 weeks initial assistance status and stuff like that.
Two l
18!
weeks of HP training at the end of that and then after one year we were 19; given our A Operator Status.
20' 21j FOSTER:
Thank you Mr Shannon at this point I am now going to turn the i
22 interview over to Mr. Yuhas and Mr. Creswell.

What we would like to do is have you described to us first how A
you became aware of the incident, what you became aware of, when yca 3!
reported for duty and what actions you took in the period frcm 3/28 4
through midnight Friday 3/30.
After you have in your own words described what you done we will go back and ask you some specific questions to 6
try to bring out additional details.
At the conclusion of that part of i
the interview we will give you the opportunity to bring forth any O!
comments or criticisms complementary or otherwise related to the incident 9
and to Met Ed in general.
So if you would please begin by telling us 10 how you heard of the incident and your involvement for the first three 11 days.
12!
i 13l SHANNON:
I received a phone call the morning of the 28th from a friend 14 asking me what was going on.
I had no idea what was going on at the 15:
time cause I was in bed.
After they talked to me for awhile I then got 16i up and listened to the radio tried to here what I could hear and of 17 course the radio was making some announcements about a possible meltdown 18I at TMI and what not.
And I sort of didn't get too upset about it.
I 19!
reported in as normal shift schedule at 3:00 in the afternoon on the 20 28th and found that I couldn't get the north gate.
I was told to 21(
proceed to the observation center, which I did.
And frcm there I was 22 contacted by a shift foreman and he said that I should proceed to the 23l Island to get into a control room, which I did.
I came into the Island 24 and everything was pretty well evacuated except for the control rocms.
25l w
t
l i
(

1 i
I reported to Unit 2 control room and just stood by, we were respirators 2f at the time.
I didn't get a job until maybe 9:00 or so and I was 31 instructed to go into the Auxiliary Building and put some nitrogen on 41 the ccre flood tanks, increase the pressure on the core flood tanks, 5
which I did.
Increased it to about 600 pounds and I was then given 6
another job to go in and try and make some rocm in our neutralizing tanks by pumping them over to Unit 1 for evaporation so we could pump 8I the water from the auxiliary building floor into our neutrali::ing 9
tanks.
Once I got in we found out that the switch gear was deenergized 10f for the neutralizing tank pumps and it would not start so we started 11l i
invest gating the problem there and thats about as far as we got.
We 12!
never did find out exactly what was wrong with switch gear and I left 13!
the Auxiliary Building and told them that I wanted to get my TLD read 14!
because I figured I had received quite a bit of radiation to the levels 15' in the Auxiliary Building and I did read it.
And I had 3.2 Rem at that 16 time.
That was about 11:00.
And I was then instructed to leave the I
17!
Island proceed out to the observation center and get a whole body count 18l for that.
At that time there was no whole body counter available yet, 19!
and I didn't get a whole body count until the next day, the 29th.
When 20!
I came in at 3:00 I was not allowed on the Island again due to the 21 radiation I did receive and I did odd jobs around the observation 22l center and the 500 KV substation such as frisking the vehicles coming 23 24!
I 25; i
l 3
f e
l l
5 l'
off the island and frisking any possibly contaminated people coming off the island.
And if they were contaminated then proceeding to help them 3'
l decon.
And I did that same job for approximately the 3 days.
4j i
5 YUHAS:
Thank you, at this point we are going to go back now and ask 6!
for more specific details.
When you reported to the observation center i
7 you stated that you were contacted by a shift foreman.
Do you know who 8{
that shift foreman was?

Yes, Conway, William Conway.

13[
you at that time have your TLD and pocket dosimeter?

i 5
SHANNON:
Yes, I believe was around 4:00 to 4:30 somewhere around s
6 there.
I parked my vehicle at the north gate and I rode in with a l
7 truck load of other people.
I am not sure who they were and I believed 8
we had to wait for mask at the north gate,... respirators at the north 9
gate.
They logged us in as they normally would by badge numbers and 10' names.
11:

YUHAS:
What sort of respirator did they provide you at the north gate?

I don't believe they had iodine cartrid-'.s that I know of, I 19f can't really remember the exact cartridge that I did have on.
20; i
21f YUHAS:
Prior to this incident did you have the MSA GMR combination 22!

When you arrived at the process center could describe the f
condition of the process center?

SHANNON:
There was no one in it, it was empty.
5 6l YUHAS:
That means that there was no security person there, that the 7
normal gates, key gates were not activated, that there was no metal 8
detection equipment in function and that there was no chemical detection 9
equipment in function.

SHANNON:
As far as people there, Joe Logan, Jim Seelinger, Mike Ross, f
6:
l George Kunder, those were the upper management type people that I can think of... then the normal shift CR0's.
Theii was a supervisor, Bill 8!
Zewe, Greg Hit::, Joe Chwastyk, Brian Mehler, those are the supervisors 9I that I can think of as being there.
Operators, some were out in the 10' plant but I'am not really sure who all of the operators were.
There 11 were at least 7 or 8 operators.
I 12!

Did you observe a control point established in the hall way 2!

31 l
4I SHANNON:
I wouldn't consider it a control point.
I think there was a c
step off pad at the entrance of the service Building from the Control 6
Building.
But there was a lot of Scott air pack boxes and coveralls I
7l and other radiation type equipment laying in the hallway, but there was 8l no control point.

Can you descrbe what you did frcm about... it must have been 15 about 16:30 by the time you got to the control room until your first 16 assignment at 2100?
1 17 18i' SHANNON:
I stood by and just tried to.
well we were answering phones 19!
a lot of phone calls, establishing communications with the observation 20l center, keeping people informed of anything that was happening.
And in 21I particular I think of Jack Herbein was calling up all the time and was i
22' giving out status reports on what was happening.
And I was just trying 23J to stay out of peoples way so that they could get everything under 24l control.

YUHAS:
Can you describe for us who specifically told you to make this 6i trip in the Auxiliary Building and the reason for making the trip?
7l l

SHANNON:
The actual order came from Joe Chwastyk, reason being he 9I wanted to have more nitrogen pressure on the core flood tanks, they 10!
were down about 400 pounds and he wanted to pressurize them in case we i
11!
needed them.

Well, I was questioning the order the foreman, and I believe 20!
it was Conway, was giving me and I went out into the front and the two 21!
of us were standing there and he was telling me why don't you go in.

Proceeded right down to the rad waste panel where it was 10 ren 20l and discovered that the pumps I neo:dd to pump the tank with were 21i deenergized.
Called the control room and informed them that, and 22l talked to Brian Mehler and he said find a spot of low level, as low as 23!
you can find.

the 1311 radiation monitor on our discharge to the river.

since that was such a high background that was restricting our pumps 61 from starting.

I noticed that there were... specific pumps that had been 2f turned off were all the pumps that were effected by the WDL 1311.
I 3l That's what led me to the conclusion that it was the 1311 that was 4l preventing us from using the pumps.
That's about all I noticed really.

You didn't notice any tank levels or any.

Oh I did look at (unintelligible) tank levels and they were 9l both somewhere around 10 feet and the Auxiliary Building sump level 10' was... sump and sump tank were both full.

So what you did was go in the Auxiliarj Building and open a 10 manual valve?

Yes. well I opened the regulator first to pressurize the line 13i to 600 pounds and I then went in and I opened the valves up.
I knew it 14 would take a while.
We just isolated at the manifold.

After you came out of the Aux Building did you go back and read 14l the regulators to see what it read pressure wise?

No I went up to the control room cause I knew it would take a 17 while and we were watching the pressure from up there.

them.
That did upset me a little bit but I don't want to say, but the 61 people that we have in the HP department as far as technicians, I didn't have a whole lot faith in before and I imagine they were busy I 8!
don't really know.
I hate to put them down withcut knowing the whole 9
story but we should have had some support.
I had thought of it.

How was your relationship with the health physics general 1
