Procedure -- Plant Procedure 24812-1.
l 2
It's my understanding that you and another I&C 3
technician by the name of Wilkins were conducting a 4
surveillance on this equipment on January 28, is that 1
5 correct?
i 6
A Yes, sir.
7 Q
Could you, in your own words, explain to me what 8
took place from the point in time you first started doing 9
that surveillance?
l 10 A
Yes, sir.
During the Unit 1 outage, there had been j
11 some -- two additional RTDs placed into the delta T TAVG i
12 loop, RTD bypass.
]
13 Q
RTD meaning?
14 A
Resistance temperature devices, which provide j
15 inputs for the hot leg and cold leg.
16 Q
Okay.
17 A
Temperatures.
We had set -- we were given the 18 surveillances for Unit 1 and Unit 2. These can't start until i
19 the due date which is after 12 o' clock on a -- you know, we 20 wara working nights at that time.
21 Q
Okay.
22 A
The test setup involved four RTD simulators, seven 4
23 digital fluke meters, a number of 0 to 10 volt voltage 24 sources and ramp step generators.
It's a very elaborate test i
25 procedure.
1 i
4 r
n,
Page 5 1
Q All right.
1
]
2 A-It requires a cart.
We took the cart into place, j
3 we went.through procedure of our normal test setup --
4 Q
Where -- just exactly where in the plant were you 5
conducting this surveillance?
1 6
A In Protection Set -- I believe it was -- in 4
7 Protection Set 3, which is in the main control room. The 8
control room area is rather narrow in the protection sets and i
~
control sets and other process cabinsts.
The cart is rather 9
4 10 wide, we had all our test equipment on the cart.
I was 1
11 standing directly in front of the racks as we were setting 1
l 12 up.
I had the rack.
The test equipment was here on the l
13 cart, Marcel was on the other side of the card with the, 14 procedure and the data sheets.
He was reading, I was 4
15 plugging.
i.
16 Q
When you say plugging, you were taking readings --
17 A
No, sir, the initial setup is -- the initial test l
18 procedure is quite elaborate where you set up your t
l 19 installment RTD in this card location, install another.RTD l
20 into this card location, install another RTD into this one.
21 And provide a voltage nource into this card, put a meter to 22 this card -- it's very systematic and orderly.
23 But once we got everything in, you set your 24 voltages up and we started our procedure.
Everything went i
25 well, the initial readings came in, the dynamic -- or the i
i i
+
s Page 6 1
ramp step generator where we put a ramping increase in and 2
check the time for a bistable to come, all that'was going i
3 well.
l 4
Then we came to a bistable, the 431H if my memory 5
serves me correctly --
I 6
Q Wil'1 these documents help you at all?
i 7
A Yes, sir.
8 MR. ROBINSON:
Let the record reflect that the 9
witness is reviewing Revision'16 of Analog Channel
~
10
' Operational Test Data Sheet 1, pertaining to procedure number i
11 24812-1.
l 12 THE WITNESS:
I will probably be referring to this 13 as an AC07, 4
i 14 MR. ROBINSON:
Okay.
1 15 THE WITNESS:
That's typically what we call it, 16 it's an analog channel test.
17 Yes, sir, it was a 431H, if this is our document.
18 BY MR. ROBINSON:
j 19 0
Is that your handwriting, are those numbers your 20 handwriting?
4 21 A
No, sir.
22 Q
It is Wilkins' handwriting?
23-A Yes, sir.
We got to that point, I'm on the rack, t
24 he's on the other side.
Okay, I'm varying a voltsge,
+
25 watching a bistable, which is a light emitting diode that's i
Page 7 1
extinguished or on.
2 Q
Okay.
3 A
Okay, I've got my mark such and such a voltage and 4
then I go pick it up on the other side, mark and get my 5
voltage.
That's out, that's out of cal.
6 Q
Out of calibration.
7 A
Out of calibration, it's outside the acceptable i
8 limits.
9 Q
Now are we talking about this --
i l
10 A
On illuminate and extinguish.
11 Q
Are we talking about this, voltage 4.130?
s 12 A
Yes, sir, as measured on a digital volt meter.
13 0
Okay.
So what did you do next?
14 A
My fiz.st impulse was -- there was a lot of other testequipment--youknoh,Itoldyouwehadalotinthere.
15 16 There was another spurious alarm coming in on another cabinet 17 which involved a lot of other test leada and records hooked Q
Y i
18 up, you know, multi-channel recorders hooked up.
My first Ql %v T
19 thought was tweak, but I.didn't.
I said no, that's wrong.
}/
20 Q
What do you mean by tweak?
e 21 A
Adjust it in.
It was close, ly $
22 Q
Adjust the --
23 A
Adjust the bistable.
\\
24 Q
Okay.
g.
25 A
But I did not do that.
-I- = = M nn.
that's wrong, T
(
j Page 8 1
we're not going to do that.
We called our foreman, Bob Neal.
s 2
Q Bob Neal, okay.
3 A
Bob --
4 Q
What did you tell him?
5 A
I said we've not a bis *=hla n t Le aroT, what.
6 do you want me to do. He sg d well -- I don't know whether 7
his term was w=
1 t'r==ke it rioht or we've got to fix it i
8 or 1.et -- not on-Then I called Quality Control Section, 9'
Roy Whitaker.
Told Roy that we had a bistable out.
10 Q
Is this -- you're talking to Roy on the telephone 11 or did he come over?
12 A
Yes, sir.
I said we're on hang-on or something --
13 I don't know exactly what I said but I informed him we had a 14 bistable out on a delta T loop, we needed him for as-left 15 values.
16' I don't remember whether Bob got there first or 17 whether Roy got there first, but both were there at the rack, I
18 and I showed them with the voltage source going up where we 19 were, and the values here that we're out.
And ther. we 20 adjusted the bistable to the value right here.
21 At that time --
N 22 O
Wait a minute -- while Bob and Roy were there, you
~~~~,,_
23 adj_usted the bistable tot ha 3.990?
24 A
Yes, sir, that expected value, yes, sir.
25 Q
Okay.
O l
Page 9 1
A At this point, I tliought I was doing the right 2
thing, this was out on my data sheet.
And we'd called QC, 3
we'd gotten in touch with Bob.
We made it right -- in my 4
mind, we made it right.
5 Q
Okay.
6 A
And then I think Bob left -- he would have to come P
7 back in order to an independent verification on the 8
completion after we restored the loop to service to make sure 9
that the bistables were all proper and all channel status 10 lights were extinguished.
So he couldn't be there with us 11 while we were restoring the loop.
12 Q
Was Roy with you?
j 13 A
Roy -- this is -- Roy witnessed the as-left to the 14 ACOT data sheet, and he said okay, where do I sign, what did 15 I just witness?
And then it hit me about that time, you
)
m 16 know, when he had to sign a step in the data sheet, that he w
17 witnessed as-left value taken under this step of the
\\
18 procedure.
19 Q
Okay.
20 h
That's what his signature means?
21 A
That's what his initials means, that he witnessed 22 that.
23 Q
Just looked at and verified the as-left values?
f 24 A
He verified the as-left value Der that step.
25 Q
And Bob saw that, essentially saw the adjustment to 4
4 i
Page 10
~\\
1 the 3.990 before he left?
f-2 A
Yes, sir.
h 3
3 Q
All right.
f 4
A To the best of my recollection, sir,' yes, j
5 Q
Okay.
And --
6
'A At this time, you know, Roy signed that -- and 7
someyncr + Hec==' - ' tPt'Q I reayed that we had 8
not done that step, we had --t t--
that step.
W e < H ei it to 7
i -
.9 theJK'OT value and did not do it to that value, to that art i
l 10 of the procedure.
j-11 Q
So was it just a matter of obtaining a value as 12 opposed to how you obtained that value?
In other words, l
13 isn't there a given procedure that requires you to go through 14 X number of calibration steps, regardless of what value 15 you're setting it to?
Does that question make any sense to 16 you?
i l
17 A
I don't think it does, sir.
f' 18 MR. ROBINSON:
Go ahead.
1 19 MR. BONSER:
When you find an iricorrect as-found 1
l 20 value, isn't there some other procedure that you should go 21 to?
You should come out of this ACOT procedure and to 22 another procedure?
l 23 THE WITNESS:
In the procedure, you notify your 4
24 foreman.
25 MR. BONSER:
Okay.
i s
1 1
t i
I I
l Page 11 1
THE WITNESS:
Now there is a specific procedure for 2
the calibration of the NAL card, alarm card is what that 3
means, NAL card.
4 BY MR. ROBINSON:
5 Q
Is this the procedure?
I'm going to show you 6
procedure number 23300-C.
7 A
Could I take a look at the actual delta T 8
procedure, please, sir?
9 (A document was proffered to the witness.)
10 MR. ROBINSON:
That's just an excerpt from that 11 procedure.
12 THE WITNESS:
Okay.
13 (The witness reviews the document.)
14 THE WITNESS:
I'm trying to find -- okay, this is 15 the QC hold point.
If we had -- this is actually in the 16 procedure.
I would need to go with my procedure to an 17 earlier step.
I 18 MR. ROBINSON:
And just for purposes of clarifying 19 it on the record, when you're pointing to something, try to 20 identify it by caying what page and what procedure.
21 THE WITNESS:
Yes, sir.
22 (The witness reviews a document.)
23 THE WITNESS:
This is the statement that I was 24 referring to earlier, sir.
"If during performance of this 25 procedure, any of the following occur, immediately notify IEC
l Page 12 1
foreman."
t 2
MR. ROBINSON:
Okay.
3 THE WITNESS:
"Any personnel error, procedural 4
inadequacy or malfunction is identified which could prevent 5
fulfillment of acceptance criteria and any test exceed 6
specified limits."
That's why we called Bob at that time.
7 BY MR. ROBINSON:
8 Q
Okay, and after that, af+-r nah e===,
how are you 9-s4Eposed to fix the problem?
10 A
We were supposed to have gone to the individual u
3 11 card _ calibration orocedure. -
l 12 Q
Did you know that at the time?
13 A
I_should have but it didn't reaister.
14 Q
Had you adjusted bistables using the ACOT procedure 15 balaza2 l
16 A
No, sir, because 95 percent of the procedures that i
17 we run, it's the same test setup for,the card calibration or 18
-- for the ACOT and for the card calibration.
19 Q'
Okay.
20 A
And this one is so elaborate that it goes through a 21 different system.
22 (The witness reviews a document.)
23 THE WITNESS:
Right here, sir.
This is the section 24 for the individual card calibration procedure.
25 MR. ROBINSON:
Let the record reflect that the e
i j.-
4
-w-
Page 13 1-
'section he is referring to is on Procedure Number 24812-1, 2
Rev Number 16, page 64, paragraph -- which pa ngraph were you 3
pointing out to me?
4 THE WITNESS:
This section right here.
5 MR. ROBINSON:
4.3.38.1.
6 THE WITNESS:
Signal comparator NAL card 7
calibration, 1 TB-431G/H.
The G/H means there's two bistable 8
channels on that card.
9 MR. ROBINSON:
Okay.
10 BY MR. ROBINSON:
l 11 Q
When Bob Neal came to where you were, did he give 12 you any instructions as to how to correct the out-of-13 calibration problem?
i 14 A
Not that I recall, no, sir.
15 Q
Was there any conversation about it being close to i
16 end of shift and the full calibration procedure is going to 4
17 take a long time?
I 18 A
No, sir.
19 Q
There was no conversation like that that you 20 recall?
21 A
Not that I recall.
There may have been, but I 22 don't recall it, no, sir.
23 Q
Do you remember saying anything like that?
24 A
No, sir.
25 Q
Were you familiar with -- I guess I may have asked 1
Page 14 1
this question before -- were you familiar with the procedure, 2
the full calibration procedure that you needed to use to 3
correct that out-of-calibration situation?
4 A
I think I should have known that, but it didn't 5
register at that time, no, sir.
6 Q
In your experience as an IEC technician, had you e
7 aver-parforn d tha+ fall calibration procedure before?
8 A
Yes, sir, many times on the loo-before it was 9
modified with the additional cards.
That's the first time I 10 had done a cal or a surveillance with the additional RTDs.
11 Q
I see. Go ahead.
12 A
You were mentioning the card cal procedure, the 13 field calibration procedure for NAL cards.
This is this area 14 right here and what it basically tells you is adjust the 15 calibration wheel to obtain values listed, but the delta T 16 procedure is spe'cific in the NAL card calibration.
This is a 17 general that is used in other procedures that are not i
18 specific, like control channels and this type of thing.
If 19 you have a card out, like multiply / divide card or a lead / lag 20 card in a control channel, you would -- it would be 21 instructions in the procedure to proceed to the field 22 calibration procedure 23300 for the applicable card.
23 Q
I see.
24 MR. BITTING:
Would you identify the page that you 25 just referred to?
i ad
Page 15 1
MR. ROBINSON:
Let the record reflect that the 2
witness.was referring to Procedure 23300-C, Rev 5, page 3
number 6 of 47.
I assume paragraph 4.4 Signal Comparative --
4 THE WITNESS:
There are three different NAL cards 5
and all three of them are listed, the type of card.
But 6
that's a generic -- that's a field cal procedure where 7
specific calibration instructions are not provided.
8 MR. BONSER:
So this is the procedure you should 9
have gone to?
10 THE WITNESS:
No, sir, I should have gone right 11 there.
12 BY MR. ROBINSON:
13 Q
You're saying that you should have gone to the 14 Signal Comparator NAL 2 Card Calibration, I guess that's ITB-1 15 431G/H?
16 A
ITB.
17 Q
ITB.
j 18 MR. BONSER:- So you did not need to go into this l
19 procedure,,the 23300?
20 THE WITNESS:
No, sir.
21 MR. BONSER:
Okay.
22 THE WITNESS:
Because see everything -- I'm not 23 sure how technical, but I know you understand this.
This is 24 where you actually put these values -- you'd have to flip 25 relay cards and actually put the test -- the rack into a
i
'Page 16 1
' system to take this test.
And it tells you adjust to this 2
voltage, adjust to this voltage, adjust to this voltage.
3 It's very specific in protection sets.
Most procedures in 4
the protection sets are very specific.
1 5
BY MR. ROBINSON:
6 Q
And did you or did you not do that?
)
7 A
No, sir, we did not.
i 8-Q And why not?
l 9
A Because when it was initially -- it didn't 10 register.
I thought I was doing the right thing when I found i
11 the ACOT value wrong.
I just didn't think.
]
f l
12 Q
Okay.
1 l
13 A
I didn't think of it until a time just -- around 14 the time
h-
00 had signed the data sheet that he witnessed i
15 that : ;p,
-*'m when it hit me.
16 Q
And he just witnessed the as-left value.
J 17 A
He witnessed the as-left value to the value on the 18 ACOT data sheet.
i 19 Q
And he was not rigning that he witnessed you 20 perform any specific procedure, was he?
Or was he?
21 A
He was signing that he was notified on this step, 22 to observe as-found data in that section of the data sheet.
23 Q
I'm going to show you a single page document, it's 24 headed VEGP 24812-1, Rev 16, page 138 of 158.
And I'll ask 1
25 you if you recognize that sheet.
.w i--
Page 17 1
A That appears to be the sheet that was completed, 2
that was filled out on the night of the 28th -- the morning 3
of the 28th.
4 Q
And who filled it out?
5 A
Marcel.
6 Q
And were readings taken to produce this filling out 7
of the sheet?
8 A
No, sir.
9 Q
How did Marcal arrive at these numbers?
10 MR. BITTING:
If you know.
11 A
I don't know.
12 Q
You don't know.
Were you aware that Marcel was 13 doing this?
14 A
After the fact, yes, sir.
15 Q
How long after the fact?
Initial}y_yhen we both realized a mistake had been h
16 A
17 ma id. a en--nt was made that -- you know, he 18 sig 6 s data sheet that ha's doina this, we've got to 5
19 com @ _tb +'-t.
R
-";;--ti--
=* that time was let's_ fill 20 out M e comment section of the ACOT data sheet that that 21 value g s adjusted to the ACOT value during the ACOT 22 pr~ adnve.
i 23 Q
And what did he say to that?
24 A
But QC sianed this.
25 Q
Yeah.
Page 18 1
A Well strike it out, have,0C -- you know, we can't 2
coge up-with another data sheet, that's not right.
3 Q
This is a conversation between you and Marcel?
4 A
Between Marcel and myself, as best I remember it.
]
5 Q
Anybody else around?
1 6
A Not to my knowledge, no, sir.
7 Q
Okay, go ahead.
8 A
I made the suggest that let's do this.
QC had q
9 gone, QC had gone home, they warr on a different schedule 10 than we were, he-was no longer there.
I was told to go 11 back -- Marcel was told to clean the oaoerwork up, which is a 12 normal situation.
After an ACOT, you have to ao back and --
x
/
j 13 Q
101o told Marcel to clean the paperwork?
14 A
It may have been Bob, it may have been just us 15 conversing about it, but I was instructed to go to Unit 2 and 4
16 perform the same ACOT on Unit 2.
17 Q
By Bob, you were instructed by Bob?
18 A
Yes, sir.
We had another ACOT -- we had two ACOTs 19 to do that night, one on Unit 1 and one on Unit 2.
The one 20 on Unit 2, I went to proceed to do it and at one time when I 21 was doing that, Marcel c===
by and said nc'a nnt here, we've v i t-en==
up with the' data sheet.
We can put in the block 22 e
23 we rrde : nirtake.
1 24 Q
Marc _a1 i=
+=1 tina von this?
25 A
Yes, sir.
I said we made a mistake.
e m
l I
Page 19 1
Q Oh, okay.
1 I
2 A
We made a mistake, let's write down what we did it 3
to, let's just ' fess up.
But at that time, we were fully i
1 4
thinking that we had made everything right.
That was our 5
mindset at that time.
6 Q
The hardware, the electrical equipment.
7 A
Yes, sir, we had made this right.
This was out, 1
8 they had been having trouble with this loop spiking and, you j
9 know, spurious alarms coming in.
We've had people in there 10 with recorders, it's very possible -- it's real easy to brush 11 a bistable and that was in my mind, but I knew we had made a 12 mistake.
j 13 Q
So did Marcel finally prevail over your idea of 14 strikina out the QC signature and makina the comment 7 15 A
I_never suggested to get QC to strike -- you would
~'
- 16 havs te gr' +ha DC inspector there.
17 Q
Yeah.
18 A
To strike it out himself.
19 Q
Right, okay.
20 A
In_ y e-+ien_of not saying anything, I knew -- I 21 knew what was going on.
22 Q
Okay.
23 A
I knew what was going on.
24 Q
And what you knew was going on was that Marcel was 25 fillin" ~2* *his Data Sheet 37 with figures that would
Page 20 1
pond to the figures that you actually obtained 2
on your. g.
3 A
Yes, sir.
v 4
Q There continued to be some spurious alarms with 5
that bistable after you reset, didn't there?
6 A
Yes, sir.
That's what got the people's attention 7
who went out the next day, the day shift.
8 Q
Okay.
That is essentially how the problem got 9
traced down.
1 10 A
Yes, sir, exactly.
It was a turbine run back 11 signal, it was a two out of four coincidence and one of the 12 two was flashing in.
13 Q
So it's your testimony here today that due to the 14 fact that you stood by and didn't stop Marcel from doing 15 this, it happened.
This was not a mutually agreed thing i
16 between you and Marcel?
17 A
I'm not sure exactly what you're asking.
18 Q
Did -- in the end when this sheet eventually got 19 prepared and turned in --
20 MR. BITTING:
You're referring to Data Sheet 377 i
21 MR. ROBINSON:
Yes, Data Sheet 37, Rev 16.
22 BY MR. ROBINSON:
23 Q
When that sheet not prap=*ad a nri turned In. avCyou 24 saying that you did not agree with the way that was handled?
25 A
I.ddd not agree with it, but I did not challenge s
1 1
Page 21 1
1,t,
t 2'
Q You allowed it to happen.
3 A
Yes, sir.
~
4 Q
Is_ Marcel senior to you?
/
5 A
No, sir.
6 Q
Do you have any responsibility for oversight over 7
Marcel or are you essentially equals in your job?
8 A
We're equals.
9 Q
We may have already gone over a number of these 10 items, but I have a list of specific questions that the 11 Enforcement people of NRC have requested me to ask you.
12 A
Yes, sir.
l 13 Q
The first question we've pretty much covered.
ave 14 you described everything that you are aware of regarding that i
15 particular incident now?
Is there anything that has happened 1
16 regarding any other data sheets that I don't have he.'re or
\\
17 other procedures that may or may not have been followed?
18 A
No, sir, there's nothing else other than the fact 19 that the data on the ACOT was. wrong, the procedure.
The root 20 cause was --
]
21 Q
The comparative -- the data that is supposed to 22 be --
23 A
The data on the ACOT was what was incorrect, yes, 24 sir.
25 Q
Okay.
And therefore, when you got a reading that i
1
Page 22
.1 was higher than that value, 2
A My --
3 Q
--you thought it was out of calibration.
4 MR. BITTING:
Let him finish the question before 5
you start to answer it.
6 THE WITNESS:
I'm sorry.
7 BY MR. ROBINSON:
8 Q
You thought it was out of calibration.
9 A
Yes, sir.
10 Q
And when you thought it was out of calibration, you 11 called your supervisor, Bob Neal.
12 A
Yes, sir.
13 Q
Or your foreman -- is he your foreman?
14 A
Yes, sir, my foreman.
15 Q
He told you to call QC or did you call QC on your 16 own?
l 17 A
Said we've got to get QC down here, I don't know i
18 whether he made the statement or I did, said we've got to get 19 QC for as-left.
20 Q
So Bob Neal and Whitaker both come.
21 A
Yes, sir.
12 2 Q
To the best of your recollection, in their presence 23 you make the adjustment, you do the tweak -- well describe 24 that to me.
25 A
NAL cards have a wheel.
It's not done with a
l Page 23 1
tweaking screwdriver, it's actually done with a wheel, it's a 2
little rhoostat, it's an adjustment on the card edge..
3 Q
All right.
And you made that adjustment, to the 4
best of-your recollection, in the presence of both Whitaker 1
5 and Neal.
6 A
Yes, sir.
I 7
Q And in fact, the way I understand what you said, I
8 you took an as-left reading and determined that the 3.990 1
4
)
9 reading was your as-left reading after you turned the wheel, l
1 1
10 is that correct?
I 11 A
Yes, sir, you make the adjustment and then you go i
12 down, take the bistable out and bring it in.
And if it's not t
l 13 right, you move it again.
14 Q
Okay.
15 A
That's what we did in the presence of Bob and Roy.
s 16 Q
And then, because for Bob to do an independent 17 verification of your as-left reading, he walked away.
Do you I
l 18 know where he went -- or go ahead, you seem concerned.
19 A
I don't know whether he left at that time or not, i
20 but at some point after this had happened he left.
Because l
21 he knew he had to come back when we restored the loop, to do and he could not be present while we restored 22 an independent, i
23 it, to do an independent verification of restoration.
f-24 Q
How long was it before he came back?
About.
25 A
How many more bistables did we have?
Do you have J
]
1
1 5-1 Page 24 i
1 the last sheet of this?
2 Q
No.
J 3
A There's some other values that you get on the back.
+
4 Q
Is that going to give you an idea of the elapsed 5
time?
6 A
The time, yes, sir.
7 Q
Are you sure he didn't come back until after you
]
i 8
finished them all?
Did you call him back or did he come back i
9-on his own?
l 10 A
I don't recall, sir.
l 11 Q
Well just to the best of your recollection.
I mean J
l 12 was it two minutes, two hours, 20 minutes?
13 A
It would_have been no longer than half an hour.
14 Q
And then he looked at the as-left reading ag31n --
15 no?
What did he do when he came back and verified?
I 16 A
The loop was -- all the test,equ'pment was removed.
i l
17 Q
Okay.
o 18 A
And he was verifying that the bistables and the l
j 19 relay card switches were in the desired. position for a loop 20 restored to service.
l 21 Q
And how did he do that?
Is that just a physical 22 observation?
23 A
Yes, sir.
l 24 Q
So he uses no test equipment and takes no reading t
i
{
25 at that time.
i I
e h
1
Page 25 1
A No, sir.
2 MR. BONSER:
But there is a sheet in your procedure 3
that he would have to sign off on, right?
4 THE WITNESS:
Yes, sir.
5 MR. BONSER:
That it we.s restored back to service.
6 THE WITNESS:
Restoration verification, right here.
7 MR. ROBINSON:
I see.
8 THE WITNESS:
He would have to come out and 9
physically look and make sure that all of these switches are 10 in the desired position listed, and sign.
He would have to 11 see that all the channel status lights' affected are 12 extinguished and would have to sign; all the relay card 13 switches; all the bistable switches.
14 MR. ROBINSON:
Okay.
15 THE WITNESS:
Yes, sir.
16 BY MR. ROBINSON:
17 Q
But these initials of Whitaker on page 154 of i
18 procedure 24812-1, Rev 16, just mean that he observed an as-19 left value --
20 A
The signature indicates that he observed an as-left 21 value on that step.
22 Q
Okay.
23 A
And we did not do that step, sir, we did it at the i
24 ACOT value.
25 Q
And I think -- did I understand you to kind of i
J
Page 26 1
. indicate that Whitaker almost had to ask you what he was 2
signing.for?
3 A
Yes, sir.
4 Q
Are you aware of Whitaker's expertise in QC of 5
electrical I&C type?
6 A
Yes, sir.
He's normally very thorough.
7 Q
He is?
8 A
Yes, sir.
9 Q
Was there any conversation between either you and 10 Whitaker or the other IEC tech and Whitaker regarding his 11 initials on this procedure?
12 A
There was probably, but I don't recall.
There had 13 to have been, sir, but I don't recall the exact nuts and 14 bolts of the conversation.
I remember -- what did we do, we 15 adjusted NAL card such.and such, that type of thing. Q he 16 was trying to find the area in the procedure to initial and 17 to reference for his inspection v rert, c
s 18 Q
Do you think Whitaker knew that he was signing for 19 the accomplishment of a procedure that had not been 20 accomplished?
21 A
I think he was signing -- this is speculation on my 22 part.
23 Q
Sure, I'll be talking to Mr. Whitaker.
24 A
He was signing that he saw this value here in a 25 bistable triggerin'g of those two values.
That's what he was 1
~--
Page 27 1
signing.
I think in his own mind that's what -- we showed 2
him this data sheet, this is what we are doing, Roy.
3 Q
So do you feel that you could have arrived at that 4
as-left value in almost any method you would have chosen, and 5
as long as you would have arrived at that value, he would 6
have signed off as observing it?
7 A
could you repeat that, please, sir?
8 Q
I. guess what I'm saying is -- and it goes back to 9
my earlier question.
These initials do not mean that he is 10 verifying that you used a certain procedure to arrive at that 11 as-left value,"is that correct?
These initials do not mean 12 that he is signing that you used a certain procedure to 13 arrive at that as-left value.
They just mean that he has 14 physically observed that as-left value.
15 A
Yes, possibly.
But I can't tell what Roy was -- I 16 can't get in his mind, sir.
17 Q
All right, I'll ask him.
18 Okay, I'm now going to read you a question from f
19 Enforcement verbatim.
I think we've probably discussed th'is 4
20 but I want you to answer it again.
"What caused you to not 21 follow the procedure as written?
22 MR. BITTING:
Is that specific enough for you to 23 answer, Mr. Davis, follow the procedure?
24 THE WITNESS:
I think I can answer it.
Would you 25 give it to me again, please, sir?
a Page 28 1
MR. ROBINSON:
Feel free to help me out here, 2
Brian.
3 MR. BONSER:
You were in the ACOT section?
4 THE WITNESS:
We were in the ACOT section.
5 MR. BONSER:
Is that Section 38 of this procedure?
6 THE WITNESS:
No, sir.
7 MR. BONSER:
Where is that?
That thing is so 8
thick.
9 THE WITNESS:
It's awfully bulky.
Manual channel 10' calibration, ACOT.
11 MR. BONSER:
What section of the section is that 12 you were in there?
13 THE WITNESS:
We were in the ACOT section.
14 MR. BONSER:
Okay.
15 THE WITNESS:
What I just referenced to is -- the 16 steps in the front of the procedure guides you to what steps 17 will be performed during -- whether it's unscheduled 18 maintenance, whether it is a channel calibration., whether 19 it's an ACOT, whether it's done with ASTEC, which we no 1
20 longer use --
21 MR. BONSER:
Right.
22 THE WITNESS:
-- but all of these are -- gives you 23.
specific steps which to perform.
The step -- this is a bad 24 copy of this procedure.
25 BY MR. ROBINSON:
- e Page 29 1
Q I believe the page that you referred to me before 2
was page 64.
3 A
No, sir.
I'm going to the ACOT section of the 4
procedure now, sir.-
5 Okay, you do the last ramp steps -- I'm trying to 6
find the exact section in the procedure where we were doing -
7
- it's the last section of the ACOT.
"If as-found readings 8
are not within limits specified on analog operational tests 9
data sheet, one or more accurate reading are desired.
10 Proceed as directed below."
11 Q
What page of that procedure are you on?
12 A
That is on 22.
13 Q
Okay.
j 14 A
At the time -- I'm going back to the original 15 portion of the procedure where it says "if any value is not 16 within limits, notify your IEC foreman."
l 17 Q
Okay.
18 A
He was notified.
As I have gone back and gone over i
19 the procedure, what.actually should have taken place at that 20 time, was that we continue right on through with the ACOT, j
21 getting as-found values until we get to this step right here.
22 Q
Which step are you referring to right there?
23 Identify it.
24 A
43279.
i 25 Q
And what does that step.say?
1 l
t n
- - ' e t
Page 30 L
l 1
A-
"As-found readings are not within limits specified.
2 on analog channel operational test data sheet, or more i
3 accurate readings are desired,. proceed as directed below.
If 4
toch spec allowable limits have been exceeded, notify.OSOS j
5 and IEC foreman to determine if TA equation in tech spec j
6 reactor trip system has been satisfied.
Then proceed as 7
directed."
8 Q
So you never really got to that step.of the 4
9 procedure, did you?
l 10 A
No, sir, j
11 Q
You got to the step where it was to call your IEC 1
12 foreman or supervisor --
]
i 13 A
In the earlier step of the procedure over-here, 14 sir.
i' 15-Q
-- and you called him and you made the adjustments 16 at t. hat point.
You didn't continue with the other bi-17 stables?
I 18 A
That's true.
i 19 "If calibration limits had been exceeded, a more 20 reading -- proceed to appropriate subsection."
The 21 appropriate subsection would have been --
j 22 MR. BONSER:
This 4338?
l 23 THE WITNESS:
Yes, sir.
l 24 BY NR. ROBINSON:
25 Q
I'm going to read you a question and see if it 1-d e
n w
e--
, s o
e 1
Page 31 1
makes any sense to you.
How did you convince the QC 1
2 inspector involved to sign the procedure without review of 3
the completed document?
Brian,.can you -- the completed J;
i 4
document would be --
3 j
5 MR. BONSER:
It would be this (indicating 4
.6' document.)
Well really, it would be both of these, data I
i 7
sheets.
Data sheet 37 and data sheet 1.
Isn't that correct?
8 THE WITNESS:
Yes, sir.
I
~
9 BY MR. ROBINSON:
l 10 Q
The QC -- you're thinking that the QC inspector i
11, would have had to have reviewed both of those documents 12 before he signed here?
Would that have been necessary?
13 A
No, sir.
I don't think so.
4 O' ay.
14 Q
x 15 A
The step in the procedure that calls him to come l
16 out is after adjustments have been made to the card.
It's 17 for as-left values.
That's what he's -- that's what he looks i
i I
18 for.
And as far as convincing hLa, we showed him this was 1
i 19 the value that was on the ACOT that was required and we 20 adjusted it to that value.
1 21 MR. BONSER:
When you were doing that adjustment 22 though, you were in a different section of the procedures?
23 THE WITNESS:
We were in the ACOT.
We were not in 4
24 the card calibration procedure.
25 MR. BONSER:
Right.
And this data sheet one is j
s O
-m.,
s a
Page 32 4
1 from'the ACOT procedure?
2 THE WITNESS:
Yes, sir.
It's from.the ACOT.
It's 3
all one procedure.
It's from the ACOT section -- ACOT data 4
sheet from the procedure.
5 MR. BONSER:
What I don't understand then is you 6
were showing him a data sheet from the ACOT section and he ~
7 was signing'--
8 BY MR. ROBINSON:
~
9 Q
He was signing that step 4.3.38.18 was completed, 10 isn't that r
~
11 A
That's what the signature would i,ndicate, yes, sir.
- - ~ ~
12 Q
Arid _ ~you hadn't even rea.ched._thAt_p_oint in the

procedure y p, --
13 14 A
No, sir.
15 Q
Did you see him sign this?
16 A
I don't recall.
i 17 MR. ROBINSON:
Okay, I'm sorry, I sort of 18 interrupted your train of questions.
l 19 MR. BONSER:
No, that.was -- well let me just get 20 back to one thing that I just didn't understand.
If you're 21 in Section 4.3.38 of this procedure, wouldn't you be using N
22 thiedata sheet, Data Sheet 37?
~
23 THE WITNESS:
Yes, sir.
24 MR. BONSER:
Rather than Data Sheet 1, which is out 25 of the ACOT section of I procedure?
c..
.. ~,
j e.

l I
Page 33 j
i 1
THE WITNESS:
Yes, sir, we would.
2 MR. BONSER:
Okay, so if the QC inspector is going 4
i 3
to verify a number, I'm not sure what number he would be j
4 verifying, but if he would be verifying a number, wouldn't he j
be ' verifying a number..Yfom this data sheet or a seTp61iit 5

(
11 Q
This document -- when I say this document, the Data i
l i
12-Sheet 37 that we have here today was not even filled out at
]
13 the ti2ne the QC inspector signed off on' this procedure sheet j
14 here, is that correct?
I 15 A
To the best of my recollection, yes, sir.
16
'Q Okay.
I'm going to ask this question, see if you 17 understand it. Was the signature on the procedure, meaning 18 the QC's signature, adequate to assure that the process was i
i
(
19 properly reviewed by QC7 s
20 MR. BITTING:
I don't understand that question.
j 21 A
No, sir, I don't understand that at all.
4 22 BY MR. ROBINSON:
23 Q
Okay, here's what I think that question means.
And 1
24 you've already told me what you think this signature means.
25 A-That was speculation.
1 1
5
h' r
Page 34 1
Q Yeah, and what you think it means is that he just 2
observed the as-left value, right?
3 A
(Nodding head affirmatively.)
4 Q
So the answer to the question "does this signature 5
assure that the process was properly reviewed by QC", the 6
answer to that question would be no.
That signature is not 7
assuring that that QC individual is saying that a given 8
process was used, is that correct?
3 A
Yes, sir.
10 Q
Okay.
Did the communications between you and your 11 supervisor reflect the appropriate corrective actions you 12 should have taken to correct the out-of-cal situation?
The 13 conversation between you and Henl.
14 A
No, sir, they did not.
15 Q
Okay.
What did that conversation reflect?
16 A
(No response.)
1 17 Q
Did your supervisor ever tell you what procedure j
1 18 you needed to use to correct that out--of-calibration 19 situation?
i 4
20 A
No, sir, not really.
I notified hLa this was out.
21 Q
I understand that.
l 22 A
And the proper course of action would have been to j
23 proceed right through with the ACOT to the end of the ACOT.
i 24.
Q But you know that after the fact.
l 25 A
I know that after the fact, sir, yes.
i
o Page 35 1
Q You're saying that you didn't know that at the 1
2 time.
3 A
I was going through the procedure and I had read
)
4 the section " notify your foreman if anything" --
5 Q
And you stopped there.
6 A
Yes, sir, I stopped and called hLm.
7 Q
He came and talked to you. Did he give you any 8
instructions on how to correct that calibration?
9 A
Other than let's make it right, or whatever that 10 term was that he used, no, sir.
.s 11 Q
Now you've already testified that while he was j
12 still there and while the QC guy 'fas still there, you made l
13 the correction.
14 A
Yes, sir.
I I
15 Q
Did anybody tell you to do that that way or did you \\
I 1
16 just decide to do it that way on your own?
17 A
At that point, I thought I was doing it the right 18 way -- I honestly thought it was right.
19 Q
So the answer to the question is that you decided 20 to do on your own?
(
21 A
Yes, sir.
j 22 Q
Did Bob Neal criticize that action in any way?
23 A
No, sir.
I f
24 Q
Was that fine with him?
25 A
Yes, sir.
Page 36 1
Q Okay.
Are other procedures that you perform during 2
the course of your duties susceptible to being violated in 3
the same manner in which this one was violated?
4 A
I'm not sure by what you mean susceptible.
If 5
someone intentionally wants to violate a procedure, any 6
procedure can be violated.
7 Q
Without really being discovered unless something 8
out of the ordinary happens.
well if'ou're talking about an unintentional 9
A y
10 violation --
11 Q
No, I'm talking about intentional.
12 A
I'm not sure that I understand what you're asking.
13 Q
From my perspective there are two problems here.
14 The first problem is that for whatever reason you did not use 15 the proper calibration procedure to calibrate that bistable.
16 A
Yes, sir.
17 Q
The other problem is the fabrication of a data 18 sheet so that it would appear that another point in the t
19 electrical train would correspond to the readings that were 20 obtained at this point in the electrical train.
21 A
Yes, sir.
22 Q
Can that kind of thing happen if someone wants to 23 do it intentionally in other procedures that you perform?
24 A
Not nearly --
25 Q
As easily?
Page 37 1
A There are other procedures where you have multiple 2
inputs.
3 Q
Okay.
4 A
Therefore, those would be more likely for this type 5
of situation.
But I'm still not sure I follow the --
6 Q
Would it be relatively easy to intentionally 7
falsify and put contrived figures in data sheets during the 8
conduct of other IEC procedures that you're doing?
Say there 9
was another situation that was out of calibration and it was 10
. going to take a long time to do the proper calibration 11 procedure.
Rather than doing that, would it be easy to fix 12 it and then falsify a data sheet like in this situation?
13 A
I'm sure there would be other situations where it 14 would be possible, but -,
15 Q
Okay.
16 MR. BITTING:
You can finish if you had more to add 17 to that.
o 18 MR. BONSER:
I think what we're asking is really 19 when doing an ACOT if you find something outside of the 20 limits here, is it easy just to go ahead and fix it without 21 going to the right procedure, like was done in this case.
I
]
22 don't think we're asking have you done it before.
I think 23 we're asking just from your general knowledge as an IEC 24 technician, wouldn't it be pretty easy to just go ahead and 25 fix something without following the right procedures.

THE WITNESS:
It's possible.
Yes, sir, e
i 2
MR. BONSER:
Is that --
3 HR. ROBINSON:
Well my interpretation is that.
4 Enforcement is also looking for other type procedures other 5
than just ACOT procedures.
6 BY MR. ROBINSON:
7 Q
What percentage of your work is doing ACOT t
8 surveillances?
i 9
A Sir, --
10 Q
Ninety percent?
11 A
No.
12 Q
Ten percent?
13 A
Twenty percent, maybe, 15.
Nights we do a lot more 14 surveillances than we do on days.
We do corrective 15 maintenance on valves, we do level control, heater secondary 16 plant work, we do loop tune, we do troubleshooting, do 17 protective relaying, we do a gamut of things.
18 Q
Okay, so in those other things that you do, are you 19 taking electrical readings?
20 A
Yes, sir.
21 Q
And are there tolerances in those electrical 22 readings?
23 A
Absolutely.
24 Q
And if one of your readings is out of tolerance in 25:
one of these other situations, would it be just as easy to

And you're not suggesting that he 1
I 4
falsified --
l 5
MR. ROBINSON:
No, no, I am not.
I'm speaking in 6
general terne, generic iorms.
7 MR. BITTING:
All right.
8 THE WITNESS:
You're asking for speculation, but 9
yes, it would be possible.
10 BY MR. ROBINSON:
i i
)
11 Q
Okay, you're exactly right, I'm asking for your l
12 opinion or speculation on it.
If someone intentionally 13' wanted to do it, to cover up a mistake or to -- for whatever i
14 reason, to keep from having to do a procedure that's going to l
15 take an excessive amount of time, you know.
16 Have you ever been involved in a situation like l
17 this before in your career here at Vogtle?
o I
18 A
For falsification?
No, sir.
I was involved in a 1
l' 19 procedural non-compliance in November.
20 Q
Mistaken?
Intentionally?
Did you do it 21 intentionally?
{
22 A
No, sir.
i 23 Q
Was it a mistake?
It was a watt-hour meter on a diesel generator 24 A
25 emergency buss that was holding up the refueling outage, s
t.
1 i
Page 40 1
coming out of the refueling outage.. This thing had to be 2
done in,the phantom load box, a non-measuring and test 3
equipment device used for controlling current and phase angle j
l l
4 on a watt-hour meter had been investment recoveriod by some 1
4 5
of our shop supervision.
We had nothing to do the procedure, 6-to calibrate this.
And I was asked if I could find a phantom 7
-- a dummy load box.
I called Northleg in Augusta, Meter 8
Lab, and they had one.
I was told by supervision, come in an l
9 hour1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br /> later tomorrow, go over to Northlag and pick up our l
10 dummy load so we can get this watt-hour meter 'done and get 11 out of this outage.
The dummy load box was different from
~
)
i j
12 the one that we had and the procedure was specific about' l
13 switch settings and this type affair.
And I did not know it 14 until the QC inspector came down and said there's no 4
l 1
15 equivalency, no load box or equivalent statement in that 1
16 procedure.
And I was DC'd for procedural non-compliance, j
17.
although I was working at the direction of --
[
18 Q
Yeah, who told you to go get the box? -
l James Sutphin said c'me in an hour late tomorrow.
19 A
o 20 At the time I thought the box was the same thing that we 21 have,'but it was a different box.
22 Q
Did he think it was the same thing?
He probably 23 thought it was the same thing because you told him.
24 A
He probably thought it was, yes, sir.
But it 25 performed the very same function but you didn't have to set
e o
Page 41 i
i the switches.
That procedures has since been changed to 3
include a no-equivalency statement and allow other load boxes 2
3 to be used.
4 Q
My question is more in the lines of have you ever 5
allowed a situation like the entry of these numbers to happen 6
before.
7 A
No, sir.
l 8
Q Did both of you decide on what you were going to do 9
here or did one of you initiate the actions and it was just 10 carried-on-by-th Ether?
e g.
11 T I 5E't' actually recall how it got started.
I know
~
12 it got to a point and I said this is wrong and we need 13 let's just write in the cosunent section what we did.
l 14
'Q'
~d~kay. ~5 h ink you've already answered this one, 15 even though I guess you stopped at a point in the procedure
{
16 where you probably shouldn't have stopped after you notified 17 the supervisor.
o i
18 A
Yes, sir.
i i
19 Q
Were the actions required by the procedure clear i
j 20 and precise?
In other words, is the procedure 21 uMerstandable?
Is that procedure confusing to you or is it 22 clear to you?
23 A
The general statement in the front about notify
)
24 your IEC supervision if something happens, in a certain i
25 respect contradicts to following the procedure down the line.
4 3
w a
2-
a r
4 m
I, Page 42 1
I knew the statement was there and I called Bob and told him.
2 I should have just kept right on with the procedure until I j
3 got to the end of it.
Now that may have been a i
i 4
misinformation on my part, maybe trying to read too much into 5
'it, but it's --
6 Q
,You kind of thought you had to stop when you found 7
one out of cal, right?
+
8 A
Yes, sir.
9 Q
Okay.
Is there anything regarding that particular
.10 situation, finding the bistable out of cal and the way you 11 handled it -- is there anything that you would like to add 1
12 that we haven't talked about that might clarify or contribute 13 to this?
14 A
No, sir, the statement that the values on it were 1
15 wrong.. I think they determined that was the root cause of i
i 16 the situation, was a faulty procedure.
17 MR. ROBINSON:
Brian, do you have any additional 18 questions?
j l
19 MR. BONSER:
No, I don't think so.
20 MR. ROBINSON:
Would you like to take a moment with 21 Mr. Bitting and just have a little conversation off the 22 record and decide if you want to make any final statement for i
\\
23 the record?
24 MR. BITTING:
Why don't we go off the record.
a 25 MR. ROBINSON:
We'll just -- it's now 2:46, we'll 1

Page 43 1
take a five minute break and you and your client decide.
2 (A short recess was taken.)
3 MR. ROBINSON:
It's 3:48 and we're back on the 4
record.
5 I'll repeat my question to you.
Is there any 6
additional comments that you'd like to make to clarify or 7
just summarize _our discussion here today?
8 THE WITNESS:
Yes, sir.
As a result of this unfortunate incident -- and it is very unfortunate for me --
10
-I think the shop in which I work and the plant in which'I 11 work as a whole are paying much more attention to detail, 12 procedtfrally.
I know I personally am and this doesn't --
=. _ -
13 this will never hap' pen again, but I can see where in the past
~...___,
14 a procedure was confusing, well it means this, that is no 15 longer tolerated.
Now if it means this, it says tais.
Like 16 on a trip actuating device operatio'nal test data sheet that I 17 did shortly after this.
I had asked two or three years ago l
18 to include more precise test equipment, a digital fluke j
I 19 versus the multi-amp analog gauge which'is plus or minus one 20 percent.
And they included the fluke in the procedure but j
f 21 they didn't tell you where to hook it up.
Now the procedure i
22 says exactly where you use this precision instrument and no 23 longer _just throws it in the body and say use it if you want.
24 And other procedures.
Other people run into 4
i 25 procedures -- yesterday, I TCP'd a procedure myself because 3
-l l
e
.o s
Page 44 1
it was wrong.
2 MR. ROBINSON:
Meaning temporary change procedure?
6 3
THE WITNESS:
Temporary change in procedure.
4 MR. ROBINSON:
Okay.
5 THE WITNESS:
And if anything good has come from r~
6 this situation, I can see that niant-wide.
7 bCR. ROBINSON:
Well that's good.
It's good that 8
you appreciate that.
9 I appreciate -- anything else that you want to add?
10 THE WITNESS:
I can just -- I'd just like to say 11 that this will not happen again.
12 MR. ROBINSON:
I appreciate that.
13 You came here freely and voluntarily today, there 14 wasn't any pressure or coercion put on you to come here.
15 THE WITNESS:
Not in the least, not in the least.
16 MR. ROBINSON:
I thank you for your time and your 17 cooperation and this interview is now completed, it's 2:51.
