MR.
IBARRA:
I'm Zose Ibarra from the NRC and I'm 4
a member of the IIT.
And we have Dave Barrett from Niagara 5
Mohawk and Frank Ashe, also another team member from the 6
IIT.
Dave, if we can get started by stating your name, 8
your position and your experience with the company, please.
MR.
BARRETT:
My name is Dave Barrett and I work 10 electrical maintenance reporting to Steve Doty and I have 14 11 years with Niagara Mohawk.
One year as an operations down 12 at the steam plant and 13 years as electrician.
I'm a 13 chief electrician at the present time.
14 MR.
IBARRA:
Dave, at the start of this incident, 15 what were you tasked to do and can you describe your -- the 16 work that you did after the event?
17 MR.
BARRETT:
At the beginning of the event I was 18 off site, so at a point in time where we could get on site, 19 we reported to the OSC and we were -- I was part of a damage 20 control team, but never went out that day.
21 MR.
IBARRA:
Okay.
As far as any maintenance or 22 whatever tasks you were involved with, the equipment -- any 23 time after the event, can you explain to us what you did do?
24 Any surveillance, any testing?
25 MR.
BARRETT:
After the event?
MR.
IBARRA:
After the event, yes.
MR.
BARRETT:
Actually none.
MR.
IBARRA:
In other words -- okay.
Have you 4
done any meggering, any electrical testing on the 5
transformer that went bad?
MR.
BARRETT:
No, I haven'.
MR.
IBARRA:
Okay. Are you involved with the daily 8
surveillance of those unit?
MR.
BARRETT:
We do the weekly yard, you know, PM.
10 It's assigned to one form and each week they just have their 11
- own, you know whoever personnel are and our crew, we just 12 assign them to do it.
l 13 MR.
IBARRA:
- Okay, can you tell me what's involved 14 with that?
15 MR.
BARRETT:
They take readings on all the 16 transformers as far as levels, temperatures, pressures, as 17 far as what equipment is operating on the equipment, you 18 know, like fans or pumps.
They do a yard inspection as far 19 as the breakers, PT's, CT's, visual inspections on the bus, 20 visual inspection is basically the whole yard.
21 MR.
IBARRA:
Do you have a
procedure that you 22 follow for this?
23 24 25 MR.
BARRETT:
- Yes, we do.
MR.
IBARRA:
Is it one?
MR.
BARRETT:
Yes, there's one.
It's an N2-EPM-
1 D690 procedure.
Yeah, it's weekly yard readings.
MR.
IBARRA:
Okay.
Are you involved at all with 3
the oil sampling?
MR.
BARRETT: If it gets assigned to you.
It's a
5
-- you know, it comes up, I'm not really sure, maybe 6
quarterly and it's just assigned to a foreman and they just 7
-- they go out and take transformer oil samples for all the 8
transformers out in the yard.
MR.
IBARRA:
Okay.
Are you involved with any of 10 the repairs on the ops that went down?
12 zs 14 MR.
BARRETT:
Not at this time.
No, nothing.
MR.
IBARRA:
Have you ever worked on those?
MR.
BARRETT:
Yes.
MR.
IBARRA:
Okay.
What type of mechanism do you 15
- use, work order or 16 MR.
BARRETT:
We usually work right under a
DWR or 17 a
WR and usually work in conjunction with I&C and just 18 support them as needed.
19 MR.
IBARRA:
Do you recall what type of problems 20 you have corrected -- corrective maintenance in other 21 words?
22 MR.
BARRETT:
As far as corrective maintenance 23 would be we have changed the motor operators for like the
'4 maintenance supply breakers.
We'e worked on the SCR legs, 25 recreating the SCR's.
Changed fans -- the cooling fans for
,I
5 1
either the legs or the cabinet coolers.
Done some trouble 2
shooting on some electrical malfunctions.
You know, fuse 3
replacement.
Usually we do the you know, the mechanical 4
end of it.
As far as breakers and actually hard, -- you 5
know, wire equipment and stuff like that.
MR.
IBARRA:
When you do some of this work, 7
especially on the
- UPS, do you all follow procedures and how 8
is that done?
Do you just take orders from somebody 10 9
verbally?
MR.
BARRETT:
Yes.
There's no, you know, on the Jg 11
-- you know like the DIVs, or the CAT-2, you know, UPS's,
'i 12 there's no real procedures.
MR.
14 but as far as 15 provides IBARRA:
Right.
Those are not safety relate'd, how do you take the instructions?
I mean who 16 MR.
BARRETT:
Right from the I&C tech.
You know, 17 because he is more knowledgeable.
It's basically their 18 equipment.
19 MR.
IBARRA:
You'e assisting them in other 20 words?
MR.
BARRETT:
We'e assisting them.
We'e usually 22 the support on the WR, you know support copy and the lead 23 copy would go to the I&C department.
24 MR.
IBARRA:
Okay.
As far as the daily checks on 25 the transformers, finding out that the fans are running or
6 1
whatever other basal
- checks, do you all have anything to do 2
with that or is that operations?
Who does that, basal 3
checks?
MR.
BARRETT:
We do, you know, a daily and we do a
5
-- every -- seven days a week we do the transformer and 6
switch yard checks and then OPS does some type of check.
7 You know, I don't know what they do, on, I believe every 8
shift.
They go out in the yard and look at -- well, 9
whatever parameters they look at, I don't know.
I know they 10 do go out in the yard.
12 MR.
IBARRA:
Okay.
MR.
ASHE:
Prior to this event, do you recall any 13 specific anomalies with the main transformer, the electrical 14 distribution system within your area of maintenance 15 activities?
16 MR.
BARRETT:
Only -- I haven',
because I haven' 17 done the yard readings.
- Just, you know, word passed around 18 in the shop as far as the higher temperature on B
19 transformer, you know, through doing the R readings, they 20 said it was running higher than A or C.
That's really the 21 only thing.
I knew there was a
CT that had -- out in the 22 yard that had moisture -- a little bit of moisture in it.
23 And the moisture indicator was showing a little bit of red 24 and besides that nothing.
You know, I haven't been involved 25 in it.
7 1
MR.
IBARRA:
Do you recall what timeframe they 2
were talking about?
MR.
BARRETT:
probably -- you know, the weeks -- a 4
couple of weeks preceding.
MR.
IBARRA:
Previous?
MR.
BARRETT:
Yeah.
Previous.
MR.
IBARRA:
Okay.
- Okay, any other maintenance 8
that you can think of that you do that are related to the 9
UPS unit that failed or to any of the transformers in all 10 three phases?
12 13 MR.
BARRETT:
Previous to the accident?
MR.
IBARRA:
No.
That you routinely cover?
MR.
BARRETT:
Nothing really routine.
As I say, 14 usually if there is WR's and they need electrical support, 15 you know, a lot of times if I'm available I'l work on it, 16 but you know, there's nothing really routine like in a 17 weekly type of thing that we do on the UPS's.
18 19 MR.
IBARRA:
Okay.
MR.
BARRETT:
There is -- like I say, they have 20 procedures; there's like a quarterly.
Quarterly rounds I 21 just got done doing that not too long ago.
That's where you 22 just kind of look at the lights, and you know, check the 23 screens for the cooling screens and stuff like that, but 24 that's nothing really major.
25 MR.
IBARRA:
On the oil analysis, if you were
1 involved in that, what would be your role in it?
MR.
BARRETT:
Basically just taking the sample.
3 All you do is you just need to get the -- they would hand 4
you the bottles and the sampling tubes and stuff like that 5
and you would just, you know, go out there and take the 6
sample; and just fillout all the procedure and the forms 7
that they send to Seventh North.
That's where they do their 8
oil analysis and just send it out to them.
Then they send 9
it back and then you record all the data that they found in 10 the procedure and you close the procedure out.
MR.
IBARRA:
How long does it take for that 12 analysis to come back?
13 MR.
BARRETT:
I'm going to say probably a couple 14 of weeks before you get the -- you know, all the stuff back 15 for Seventh North.
16 MR.
IBARRA:
Is it your group still responsible 17 for sending it out there and getting it back?
18 19 MR.
BARRETT:
Yep.
Yep.
MR.
IBARRA:
Did they keep track of what's out 20 there and what's coming back?
21 2.2 23 MR.
BARRETT:
Um hm.
MR.
IBARRA:
So you tag the oil sample.
MR.
BARRETT:
Yep, the bottles are all tagged, 24 they'e got little tags that go with the procedure.
You tag 25 them all and you wrap them and you have the data sheets
9 1
available with them, and you just send them out and they 2
send them back when they'e done.
And you just, you know, 3
take the data that they have and put it on your procedure.
4 So, this is a companywide procedure or companywide thing 5
that they do.
And we have a site procedure that we can 6
apply to it.
So we just, you know, end up taking all their 7
'data and putting it on our procedure and closing out our 8
procedure.
10 MR.
IBARRA:
Okay.
MR.
ASHE:
Your analysis
- are, or maybe your 11 opinion of the higher temperature was on the B phase, does 12 that indicate anything to you?
What would be your opinion 13 of that?
14 MR.
BARRETT:
Without -- my opinion?
About the 15 only thing I would do, would be take an oil analysis.
I 16 mean, if you didn't see any gas, you know, combustible
- gas, 17 increase and the temperature was the only thing, I would 18 probably have the TRD for the temperature switch caled, 19
- because, you know, they could go on a cal.
There was no, 20 other problems before this with them.
So, you know, if I 21 saw something like that, you know, I would look at the other 22 intercaves, look at an oil sample, you know, gas sample and 23 stuff like that.
24 MR.
ASHE:
Is it common that the RTD's go out of 25 calibration?
10 MR.
BARRETT:
I'm not really sure, you know I know 2
they -- anything goes out of cal after a while.
MR.
IBARRA:
Whenever you take this data, who 4
reviewed it or who would typically review this data?
MR.
BARRETT:
Systems supervisor.
MR.
IBARRA:
Okay.
There's a form for it that you 7
give them and MR.
BARRETT:
When you get done, anything you 9
know, you know, after you do your rounds, you would write a 10 WR, if it needed corrective maintenance.
And anything that, 11 you know, you thought was wrong, they would go out and 12 check; but at the end of the procedure when they close out, 1
13 they would sign off that they reviewed the whole procedure 14 and checked, you know, checked all the figures and stuff 15 like that.
16 MR.
IBARRA:
Have you been involved with the 17 collecting some of the data so they can assess it as of 18 today?
19 MR.
BARRETT:
No.
The only involvement I'e had 20 in the transformer so far was determing it, you know, over 21 the weekend.
I worked on Saturday.
22 23 MR.
IBARRA:
What did you do?
MR.
BARRETT:
Determed B transformer, that's the 24 only data -- you know the only thing I'e done as far as 25 that equipment.
2 MR.
IBARRA:
Any work for the UPS?
MR.
BARRETT:
Nope.
MR.
IBARRA:
Okay.
MR.
ASHE:
Is there any other information that you 5
would like to provide during this interview?
That's related 6
to your actual work activities as it might relate to this 7
event?
10 MR.
BARRETT:
No.
Nothing I can think of.
MR.
IBARRA:
Thank you.
I say terminate.
MR.
BARRETT:
Okay.
Thanks.

WR and usually work in conjunction with I&C and just 18 support them as needed.
19 MR.
IBARRA:
Do you recall what type of problems 20 you have corrected -- corrective maintenance in other 21 words?
22 MR.
BARRETT:
As far as corrective maintenance 23 would be we have changed the motor operators for like the 24 maintenance supply breakers.

is that done?
Do you just take orders from somebody 9
verbally?
10 MR.
BARRETT:
Yes.
There's no, you know, on the 11
-- you know like the DIVs, or the CAT-2, you know, UPS's, 12 there's no real procedures.
MR.
IBARRA:
Right.
Those are not safety related, 14 but as far as how do you take the instructions?
I mean who 15 provides 16 MR.
BARRETT:
Right from the I&C tech.
You know, 17 because he is more knowledgeable.
It's basically their 18 equipment.
19 MR.
IBARRA:
You'e assisting them in other 20 words?
21 MR.
BARRETT:
We'e assisting them.
We'e usually 22 the support on the WR, you know support copy and the lead 23 copy would go to the I&C department.
24 MR.
IBARRA:
Okay.
As far as the daily checks on 25 the transformers, finding out that the fans are running or
6 1
whatever other basal
- checks, do you all have anything to do 2
with that or is that operations?
Who does that, basal 3
checks?
MR.
BARRETT:
We do, you know, a daily and we do a
5
-- every -- seven days a week we do the transformer and 6
switch yard checks and then OPS does some type of check.
7 You know, I don't know what they do, on, I believe every 8
shift.
They go out in the yard and look at -- well, 9
whatever parameters they look at, I don't know.
I know they 10 do go out in the yard.
12 MR.
IBARRA:
Okay.
MR.
ASHE:
Prior to this event, do you recall any 13 specific anomalies with the main transformer, the electrical 14 distribution system within your area of maintenance 15 activities?
16 MR.
BARRETT:
Only -- I haven',
because I haven' 17 done the yard readings.
- Just, you know, word passed around 18 in the shop as far as the higher temperature on B
19 transformer, you know, through doing the R readings, they 20 said it was running higher than A or C.
That's really the 21 only thing.
I knew there was a
CT that had -- out in the 22 yard that had moisture -- a little bit of moisture in it.
23 And the moisture indicator was showing a little bit of red 24 and besides that nothing.
You know, I haven't been involved 25 in it.

BARRETT:
Nothing really routine.
As I say, 14 usually if there is WR's and they need electrical support, 15 you know, a lot of times if I'm available I'l work on it, 16 but you know, there's nothing really routine like in a 17 weekly type of thing that we do on the UPS's.
18 19 MR.
IBARRA:
Okay.
MR.
BARRETT:
There is -- like I say, they have 20 procedures; there's like a quarterly.
Quarterly rounds I 21 just got done doing that not too long ago.
That's where you 22 just kind of look at the lights, and you know, check the 23 screens for the cooling screens and stuff like that, but 24 that's nothing really major.
25 MR.
IBARRA:
On the oil analysis, if you were
1 involved in that, what would be your role in it?
MR.
BARRETT:
Basically just taking the sample.
3 All you do is you just need to get the -- they would hand 4
you the bottles and the sampling tubes and stuff like that 5
and you would just, you know, go out there and take the 6
sample; and just fillout all the procedure and the forms 7
that they send to Seventh North.
That's where they do their 8
oil analysis and just send it out to them.
Then they send 9
it back and then you record all the data that they found in 10 the procedure and you close the procedure out.
MR.
IBARRA:
How long does it take for that 12 analysis to come back?
I 13 MR.
BARRETT:
I'm going to say probably a couple 14 of weeks before you get the -- you know, all the stuff back 15 for Seventh North.
16 MR.
IBARRA:
Is it your group still responsible 17 for sending it out there and getting it back?
18 19 MR.
BARRETT:
Yep.
Yep.
MR.
IBARRA:
Did they keep track of what's out 20 there and what's coming back?
21 22 23 MR.
BARRETT:
Um hm.
MR.
IBARRA:
So you tag the oil sample.
MR.
BARRETT:
Yep, the bottles are all tagged, 24 they'e got little tags that go with the procedure.
You tag 25 them all and you wrap them and you have the data sheets
9 1
available with them, and you just send them out and they 2
send them back when they'e done.
And you just, you know, 3
take the data that they have and put it on your procedure.
4 So, this is a companywide procedure or companywide thing 5
that they do.
And we have a site procedure that we can 6
apply to it.
So we just, you know, end up taking all their 7
data and putting it on our procedure and closing out our 8
procedure.
10 MR.
IBARRA:
Okay.
MR.
ASHE:
Your analysis
- are, or maybe your 11 opinion of the higher temperature was on the B phase, does 12 that indicate anything to you?
What would be your opinion 13 of that?
14 MR.
BARRETT:
Without -- my opinion?
About the 15 only thing I would do, would be take an oil analysis.
I 16 mean, if you didn't see any gas, you know, combustible
- gas, 17 increase and the temperature was the only thing, I would 18 probably have the TRD for the temperature switch caled, 19
- because, you know, they could go on a cal.
There was no 20 other problems before this with them.
So, you know, if I 21 saw something like that, you know, I would look at the other'2 intercaves, look at an oil sample, you know, gas sample and 23 stuff like that.
24 MR.
ASHE:
Is it common that the RTD's go out of 0
25 calibration?
f
10 MR.
BARRETT:
I'm not really sure, you know I know 2
they -- anything goes out of cal after a while.
MR.
IBARRA:
Whenever you take this data, who 4
reviewed it or who would typically review this data?
MR.
BARRETT:
Systems supervisor.
MR.
IBARRA:
Okay.
There's a form for it that you 7
give them and MR.
BARRETT:
When you get, done, anything you 9
know, you know, after you do your rounds, you would write a 10 WR, if it needed corrective maintenance.
And anything that, 11 you know, you thought was wrong, they would go out and 12 check; but at the end of the procedure when they close out, I
13 they would sign off that they reviewed the whole procedure 14 and checked, you know, checked all the figures and stuff 15 like that.
16 MR.
IBARRA:
Have you been involved with the 17 collecting some of the data so they can assess it as of 18 today?
19 MR.
BARRETT:
No.
The only involvement I'e had 20 in the transformer so far was determing it, you know, over 21 the weekend.
I worked on Saturday.
22 23 MR.
IBARRA:
What did you do?
MR.
BARRETT:
Determed B transformer, that's the 24 only data -- you know the only thing I'e done as far as 25 that equipment.

to your actual work activities as it might relate to this 7
event?

No.
Nothing I can think of.
