81 MUNTER:
Okay.

101 MARSH:
Let me interject one word here just maybe to clear some confusion.
11!
Dennis, you indicated that you're normally assigned to Unit 2, but on March 12; l
28th you had been assigned to Unit 1 as a matter of cross training to be 13l l
not dual qualified, but just dual experience, right?
1 41 15; BUCHTER: Yes. We had 3 aids on our shift.
16i 17!
MARSH:
Okay.
18f 19i BUCHTER:
And we decided among ourselves that one would take each shift 20!
over.
21l 22!
MARSH:
Okay, but your normal duty assignment would've been Unit 2.
23!
24l l
25i NY o'
s a
13 l
l BUCHTER:
Yes.
1l i
2!
j MARSH: On this particular day you happened to be in 1...at the time?
31 l
4!
BUCHTER:
Yeah.
5!
Gi HUNTER: Okay, Dennis, a couple of questions a little more specific looking 7
at your experience on Unit 2.
We've had some problems as you're aware, Met 8l Ed has:had some problems as you're aware of now.
I'm sure that the E12 A 9!
and B valves on the emergency feedwater system were, in fact, closed and i
10i they were opened at 8 minutes into this particular event by Craig Faust.
11!
Have you performed the emergency feedwater surveillance procedures as a 24 12l serie and also the 27 series and the 14 series on emergency feedwater ni pumps? Have you performed those surveillances as an ADA?
14' 15.
BUCHTER: Yes.
16i i
171 l
'St HUNTER:
Can I assume you performed them more than once...since you've on 19 the plant?
201 21!
BUCHTER:
Yes, yes.
22!
i 22l HUNTER:
One of the concerns that we have is the procedure does a number of 2
things.
One of the things that it does, in fact, do is specific valve 25i a
0 9
t s
i I
i 14 l
!lj lineups and set the system up for a surveillance, also there are some valve 2
verification sheets that are done.
31 BUCHTER:
Yep.
4; t
Si i
HUNTER:
6 Do you or have you run into the condition where when you did the test, or started the test, that the valves...any of the valves on that i
gj system or the pumps were not in the correct position that you know of?
91 BUCHTER:
No.
Not that I know of.
10!
I 11; HUNTER:
Like the EF12's might have been closed, and they should have been i
open?
13i 14:
~
BUCHTER:
No, they were open all the time, cause when we do it they shut them in the control room.
16; 17 HUNTER:
Okay.
Do you...do you have a local indication of where you verified them closed or do you do that at the control board?
19!
20t i
BUCHTER:
What we usually do is talk on the page and then they tell us 21:
they're closed, and they start the pumps then.
22!
23l l
HUNTER:
All right.
Have you ever run into the fact that...have run into 2 41 25l the case where the pumps were inquota lock or in a position other than they were supposed to be?
k ihI u';
t J
6
i 15 BUCHTER:
No. You see, we go out and verify all the valves and we call 1l 2
them and tell them that we're ready to have to open the 12 valves and go l
ahead and start the pumps.
3 4j HUNTER: Okay.
Let me give you a condition of the...you are doing the 5
surveillance and you find something.
You find the EF12 A and B valves in g
7j the closed position or something local like a recire valve, more in line with your job. How do you handle that? What would you do with that?
g 91 10l BUCHTER,:
Usually call the control room and ask why it was shut, or why its out of position.
11!
12t 13l HUNTER: And would you normally talk to the control room operator or a 1
foreman?
141 d
15' BUCHTER:
Yeah.
The control room operator usually lets the foreman answer the page, and I'll talk to him.
17' 18t HUNTER:
Okay. Not just the emergency feedwater system, but also decay 19!
heat removal, other type surveillances.
Have you run into any valves being 20!
out of the position, like the 108 valves or any of they type valves or 21i pumps?
22!
l 23{
l BUCHTER:
There was a couple of valves I found out of position already.
24I' They were done... surveillance was done that day and they forgot to put them 251 back.
i
\\h C
5
-O 1
e, a
f
I i
l 16 l
l HUNTER:
Okay, and how did you find them out of position? During a routine 3
2 shift check or just by walking by and observing them in the closed position
"***?
3 l
4l
)
BUCHTER:
The control room operator usually said, " hey we don't know if g
Gj they're open yet, and we'd go check them", that's when I~went back to verify they were open.
7 8f HUNTER: Okay. And is that the limit then of your input to tnat, say it was B.. 8H108 valves or whatever, would that be the end of your input you 10l l
would say, okay they're closed, and he probably said, open them?
11!
12l' BUCHTER:
Yeah.
13l 14i riUNTER: And then you left it to him or would you...?
16i BUCHTER:
No, I'd open them if they're manual valves.
171 I
- 191, HUNTER:
Right.
Then would you get involved after that...?
20:
BUCHTER:
No.
21(
I 22l HUNTER:
...Or would you just leave it to the control room operator?
23 24!
25i n'g
\\9 cY
=
i l
17 1
BUCHTER:
I'd tell them that when they were open again and he'd do it from there.
2 3:
4j HUNTER:
Okay.
From a couple of the operators we've reviewed here the way Sj yud business, you'd have a check shift check sheet that you do and on i
6j those check sheets there are valve lineups and...
i 7l BUCHTER:
Yeah.
Some valves are on there.
g 9I HUNTER:
...Certain valves on there.
I'm speaking towards that type of i
10[
thing also...
12!
I BUCHTER: Yeah.
13) o 14:
HUNTER:
...If you find something in your checks.
If you found something out of position you normally would notify the control room and get it to the right position.
i 18!
BUCHTER:
Yeah.
Yeah, sometimes, you know, they find them out of position 19!
and you call... call up there and say they're in the middle of a surceillance 20i or doing...that they should be in a different position or else they're 21l doing a test.
22j 2l l
HUNTER: Would you log that on that sheet that...
24!
S' 25!
,u i
e a
l l
18 1!
BUCHTER:
Yeah.
I 2!
3 HUNTER:
...this is out of position because surveillance procedures is f
being run?
4 5l' BUCHTER:
Yeah, yeah.
6 7l l
suNTER:
Okay.
In a...in another area with the emergency feeewater system, 8
the EF11 valves are air operated remote control, they do have m.'.nual, auto g
- entrols on Baily Station.
Are you aware of those...
n!
BUCHTER:
Yeah.
131 HUNTER:
... types of stations.
Have you ever seen those valves in manual?
14i i
Or are they out of position...out of automatic?
151 16!
l BUCHTER:
No, not unless we operate them ourselves.
17!
18!
HUNTER: Okay.
191 201 MARSH:
Would there be conditions when you would operate them by yourselves, 21:
check them out auto?
22l r
231 BUCHTER:
Yeah.
If they had problems with them in the control room and i
24l they couldn't operate them or like a...they werer t always shut, they 25!

t 19 1,
didn't seat all the way we'd go down and manually try to shut them some 2j m re.
I 3!
MARSH: Have thera been situatic,ns such as that?
5l BUCHTER:
Yeah, I went down to operate them twice so far.
I had to...they l
thought they were leaking by and I had to go down and see if I could shut 7
them more.
8 9l
- l' MARSH
- Were you successfully in closing them more or...?
10 n;
i BUCHTER:
Can't really tell.
12!
1 13!
MARSH:
Can't tell.
Not that you got a quarter turn out of it or anything.
1Si BUCHTER:
16i We got a little out of it, but they. don't know how much you shut it.
17!
181 HUNTER:
Dennis, you are speaking of the E Fil valves right?
191 20l BUCHTER:
Yeah.
3 21:
22!
HUNTER: A and B valves.
231 Are you aware that the valves are special and in fact, they.do leak through that they're designed to leak?

Are you aware of that?

That's why they always shut the 12's.
I Si 7l HUNTER:
Okay, lets go back and talk about the 12's.
You in indicating 8l again, that okay, that the 12's would be shut...it becomes very obvious I
that if, in fact, the ll's a. leaking through, are you speaking in the g
terms that the ll's are leaking through and you're leaking back to the aux...the emergency feedwater pumps backwards or speaking in the terms of leaking from the emergency feedwater pumps when thay're on leaking into the I
131 i
14!
l BUCHTER:
15i It's leaking in.
16 HUNTER:
When...can you recall when you would have been involved in that i
17:
i king of thing of checking the ll's and possibly even watching the 12's go 18f closed or seeing them close them?
201 i
BUCHTER:
Yeah.
I don't remember when the last time I did that surveillance 21!
i was.

EFil valve and I forget which it's the A or the B.
The otter one 12!
I is nice and one of the types is... indicates high temperature the type is 131 tiis color. As if high temperature water or steam had been leaking through 14!
.the check valve back through the 11 valve...
151 16:

17 Yes.

Nope.

Have you ever walked up to the emergency feedwater pumps on your 22l 23i tours and they were rotating backwards or anything, that they were rotatirg?

23 1
BUCHTER: Yeah, the only things we had that was the reliefs would lift off

every once in a while on the suction of the motor driven emergency feedpumps.

4 And that's the reliefs you're talking about?
51 i
BUCHTER: Yeah.
61 I

Relief valves?
81 9l l

10l l
11!
BUCHTER:
12!
Yeah, it comes from the condensate system.
(
131 HUNTER:
Cond,ensate system.
But.the only way that would. relieve is if it was leaking back because that's the only source of high pressure water.
16; BUCHTER: Well this is on the suction end of the pump.
i 18[
HUNTER:
Right, but the only source of high pressure water wculd be if it 191 was leaking back to the pump from the...
20i 21f BUCHTER:
All we had to do is shut the suction valve and the relief would 22!
recede, so we always figured it came from the suction.
Or shut the suction 231 valve and the valve would 3r the relief valve would shut again and we could l
reopen the suction valve back up.
25i 9

24 I
i l
HUNTER:
Okay, I'll look at that.
That's interesting that you would...that 1

Is the relief valve on the pump side j
f the suction valve or on the tank side of the suction valve?
3 I

It's on the tank side.

It's on the tank side?

BUCHTER:
Yeah.
13!
14!

HUNTER:
Okay.
Yeah, I'll look at that.
I think that probably even confirms 161 the fact that it's leaking back through the pumps, but I'll look into that, 1
Okay.
Have you operated the emergency diesel generator surveillances 17!

Can you give me some comments on that as to how it came about?
4 51 H
e 1, at day a
.e reactor coolant pump tripped, and I had 6
f to go down and open the needle valves for cooling flow.
And I went in to 8;
perate the valve and when I came up both my arms were crapped up or contaminat ed i
end I didn't notice it, when I came out of Unit 2 HP because the background 91 was so high. When I got up to the processing center they picked it up and i
101 I walked back to Unit 1 HP to clean my arms up and all my clothing was 11:,
i 12l contaminated too cause rubbed it through the arms.
And then I couldn't wash off my arms; it was on there.
131 14i MARSH:
This was on April 6th?

21l YUHAS: Okay.
22l l
23\\
BUCHTER:
Well, I had cotton gloves underneath them.
The first pair of 2 41 rubber gir 25!
es was taped to my rain suit or the wet suits and the other one was taped passed the outer ones.
i n
l i
30 11 YUHAS: Okay. Where specifically on your arm or forearm did you become 2
contaminated?
31 BUCHTER:
To the front.
What do you call this area, right below the wrist.
Si YUHAS: Okay.
6 7
MARSH:
Your indicating the inner surface of your wrist just...
10j BUCHTER: Yeah.

0w, 1
I 31 YUHAS: Okay.
Can you describe the survey where you found the contami-y nation? What type of instrument did you use and what did it read and what 2
was the extent in terms of the area that was contaminated on your skin?
3 41 gj BUCHTER:
It was those monitors that had a Unit 1 processing center, what do t!_/ all the square ones with...
Si 7;
i YUHAS: Would this be the RM14...
81 91 BUCHTER: Yeah.
101 11!
i YUHAS:
...with the extra 210 probe?
12l 13!
BUCHTER:
Yes, that's the one.
And then I checked it out and it went off 14!
scale on the one scale and I immediately went back to Unit 1 HP.
- Finally, 15i later Pete Velez's arms were both crapped up too, contaminated.
He also 16i had to clean his.
17l 18!
YUHAS: When you went back to Unit 1 HP, did you contact an HP tecnnician 191 and ask him to resurvey you?
