! to run the compressors even though the I i
7 dryers are out of service, and I believe that 8
J when you do that, you have a condition like t 9 i you have right now on 2A and you'll end up 10 l 1

that, and I think having operated that way in

4 the past, you know, I don't think we can say 16 we've always met the statements on air quality
- l 17 that we have in the FSAR.
is on the other hand what we're saying 19 l
i is that we have inspected the receiver and !
! 20 1
i we've inspected the filters and from the j 21 i
extent of that inspection, we have not j 22 i
detected a corrosion problem, and I think 23 I
that's about as much as we can conclude.

7 projection is the same.

10 PARTON: We were showing three o' clock Tuesday l 11 (inaudible) yesterday.
12 BOCKHOLD: Three o' clock Tuesday. We're not 13 going to lose any time. Mode 3 will come quickly. That's my 14 projection.
15 VOICE: Mode 2 (inaudible).
16 VOICE: Okay. (Inaudible) mode 4.
17 BOCKHOLD: Tomorrow afternoon.
18 VOICE: Okay. (Inaudible) we don't need to 19 worry about (inaudible). ,
20 VOICE: (Inaudible) engineers (inaudible). j 21 VOICE: (Inaudible).
22 VOICE: I'm leaving, I just (inaudible).
23 BOCKHOLD: On my nickel.
24 BOCKHOLD: Let me read a paragraph. "GPC'has 25 reviewed air quality of the diesel generator of course 26 focusing on the 1A diesel air system including dewpoint 27 control and has concluded that air quality is satisfactory."
l l 1 " Initial reports of higher than expected dewpoints later l
2 attributed to faulty instrumentation.
3 That specific sentence was in reference to the March 29, 4 March 30, and March 31 work order associated with the 5 instruments that we later determined was bad, and we got the 6 V.C. Summer instrument and we figured out how to. work the EG&G 7 instrumentation. Okay.
8 This was confirmed by an internal inspection of one air 9 receiver on April 6, 1990. We looked in there and we found a 10 light film of oil and found some minor corrosion on some weld 11 surfaces. We told the NRC that. The periodic replacement of 12 control air filters were done in March, 1990. From all l
13 reports that I've heard on that is that those air filters were 14 always clean. Even in the previous outage they were very 15 clean and practically brand new.
16 We showed no indication of corrosion and air receiver and 17 daily air receiver blow (inaudible) which showed no indication 18 of corrosion and daily air receiver blow down with no 19 significant water discharge.
20 We believe, although Swartzwelder is checking, is ever 21 since we started up we've been doing daily air receiver 22 blowdowns as part of operations.
23 Further, I guess, Mike Horton, when the air' quality came 24 up, spoke to the Cooper people. And the Cooper reaction was, 25 gee, if you do these daily blowdowns, and you don't have a air 26 receiver full of water, because of the, these are marine 2
1 engines and because you have a pressure reduction going to the 2 controls, you really don't have to worry about air quality. .
- 3 You used the word that would be, you know, why you guys 4 bothering us, air quality at Vogtle was great. That was.the
- 5. flavor that came to me, okay.
6 We've done some I guess additional research. We have 7 during the '88 time frame --
well, we had some PM program 6 8 problems on working out some PM program problems.
9 The '88 time frame from' like 5/10/88 to 5/2/69, somewhere i
10- in that time frame, approximately a year ago, the year.before 11 that, we may have had one or more of the dryers out of service 12 for several months, okay,.and that's indicated here.
13 We probably were not doing good PM's on checking dryer l 14 quality at that particular period of time, okay.
l
\
15 I guess my question to the group is would that affect the l l
16 statement that we made in our letter at all? l
~
l 17 Is the other facts, the fact that hey, we blow down the 18 air dryers, the fact that we looked at an air. dryer, the fact 19 that essentially a year or approximately a year before the l 20 overhaul, you know, we did have good dewpoints would that 21 leave this statement, item.four, whole'and good?
22 KOCHERY: The question I need to answer first, 23 the dewpoint we were taking until you for the period, was it 24 used the right way? You know, we have (inaudible) seventeen,
! 25 twelve, twenty-two, these are good, you got a good. number.

l
. . i 1
1 MOSBAUGH: That's theoretically not possible.
1 2 BOCKHOLD: I mean, what we've got to basically !
3 say is our PM program before, I don't know --
4 MOSBAUGH: June, July, '89; 'right?
5 BOCKHOLD: Yeah, somewhere --
i 6 KOCHERY: (Inaudible) '89. !
7 BOCKHOLD: Yeah, somewhere in that time frame 8 our PM program was suspect. Okay, the readings were suspect.
I 9 You know, that doesn't mean that you didn't have good air. We 1 10 don't know if we had good air or bad air, okay.
11 But in the meantime we did pull the filter, okay, and we i 32 had been doing the blowdowns and all of that implies that the 13 air, although it may not during this period of time l
l 14 demonstrate the best quality, was satisfactory. j i
15 KOCHERY: (Inaudible) you can't say that we I 16 have a bad air and during the period because anytime you've l
17 got a minor corrosion, you can see anytime (inaudible). )
18 BOCKHOLD: You know, I guess I would tend to l 19 believe that we had good air based upon two things; one, 20 pulling the air filter and inspecting it, which was 21 essentially new. We didn't see any buildups of air things.
22 The second thing I guess I would tend to believe, you 23 know, you get two hundred and fifty pound air or thereabouts 24 and it sets there at kind of room temperature, okay, and your 25 dryer tries to dry it and it goes through and expansion 26 process, even if you didn't have a dryer, it gces through an 4
\ . .
i l
! 1 expansion process, the control air gets drier in my opinion.
2 -At least I think that's correct.
1 3 You know, you go from two hundred and fifty pounds or two j 4 hundred and ten pounds at the lowest to sixty pounds. It gets l 5 a lot drier. So the controls themselves are gonna see dry I l 6 air.
7 So I would then conclude, if my logic is correct, I would 8 conclude that our statement here we made on air quality is l
! 9 still a valid statement, right.
I 10 VOICE: (Inaudible). '
11 MOSBAUGH: Yes. You know, we responded in this 12 generic letter and stated what our air quality was.
13 We did state that our air quality, the maximum dewpoint 14 acceptance criteria for the Vogel air start system has been ;
i 15 established at fifty degrees F at system pressure. See FSAR 16 table. That's what we said our requirements are.
17 Dewpoint criteria was established based on a design j 18 capability of the air start system ' and a minimum diesel i i
19 generator room design temperature.
20 So basically we said that our criteria is fifty degrees l 21 F at system pressure.
l 22 BOCKHOLD: Yeah, that's what we said in the FSAR 23 (inaudible).
24 BOCKHOLD: We sometimes will not meet that and 25 we haven't met that in the past or where we didn't have a good 26 PM program to demonstrate it periodically. My question really 5
l.
l 1 focuses on this recent George Hairston letter and how long --
- . you know, I believe from what I've heard from all the experts
~
3 that Item 4 here is still valid.
l 4 I mean, we believe that we've had satisfactory quality l
5 air going to the control system.
6' KOCHERY: Yes, I think that because the dryer 7 . . . the filter (inaudible).
8 BOCKHOLD: Given the fact that you have an 9 expansion process that makes the air drier.
10 MOSBAUGH: Again, George, I say, you know, it 11 depends on what you're going to call satisfactory.
12 If you're going to say satisfactory is what we said in 13 response to the generic letter, I'm not sure that we can show 14 that we've met that criteria.
l 15 The problem is that you can't tell what any of those 16 numbers are because the way the PM's done, you just can't I 17 tell.
l 18 You know, there's a number down here, but there's no 19 calculation. They're doing the measurements at atmospheric 20 pressure, yet they need to be corrected back to a system 21 pressure, you know, --
22 HORTON: You can't prove that statement.
23 MOSBAUGH: -- and we're getting high numbers.
l 24 HORTON: (Inaudible) documented evidence to l
25 prove that statement. There's nothing to back that. You've 6
l l .
- 1. got to figure that that ~ statement is true based on our 2 observations and --
t 3 BOCKHOLD: We've made engineering judgments, 4 okay, on'this particular statement. I would go ahead and --
5 MOSBAUGH: You know, we're saying there's no 6 internal corrosion that we're observing, therefore air quality 7 is met and that may or may not be relatable.
l 8 KOCHERY: The air receiver was good you'can see 9 the wedge filter you can see the differ:ence.
10 STOKES: I guess it doesn't meet the specific 11 numbers criteria but based on our judgment when we blow it 12 down three times a day and operations says based on what we've-13 'seen on the filter and everything else no corrosion, we have.
l 14 to say it's acceptable --
but it doesn't in fact meet the 15 numbers.
16 HORTON: I think Al's concern is the lack of 17 documentation.
! 18 MOSBAUGH: The IIT team has -made' recent
[ 19 requests, George, for all these work orders, okay. They've 20 asked for all these --
21 BOCKHOLD: I'think at ten o' clock I'll talk to f 22 IIT team about going back on our past work orders in our'PM 23 program in #88 was not as good as our PM program has been in 24 'the past year, basically, in '89 and going to '90, and we'll 25 provide that information. It's still our engineering judgment 26 that we had satisfactory-air quality. I think that's -- :

l 1 BURWINKLE: The expansion of air from receiver l 2 pressure to eighty pounds is going to result in about an 3 eighty degree depression of dewpoint --
pardon me, thirty 4 degree depression at dewpoint. .
5 VOICE: (Inaudible).
6 VOICE: Yeah.
l 7 VOICE: Yeah.
l 8 MOSBAUGH: So the receiver --
9 BURWINKLE: The absolute worst case would be 10 water laying in the bottom of the tank on a hot day, you'd 11 have had, what, a ninety degree dewpoint or se.
12 MOSBAUGH: Okay. The other thing that happens 13 with a system like that is normally your receiver temperature 14 is elevated when your compressors are operating because of the l
15 heat, but a ninety or a hundred would be a good number.
. :L 6 BURWINKLE: But we store air in those for such a 17 long time.
l i ,
18 MOSBAUGH: That would only be a short period !
19 effect.
20 BURWINKLE: Yeah.
21 MOSBAUGH: I think that's probably a good 22 starting point.
23 BURWINKLE: You get about thirty degree 24 depression of a dewpoint for that expansion so whatever we l
25 theorize the maximum in the receiver was, we're sure we had 26 thirty degrees lower at the controls.

. , , , , . . - . . -, ,-*n-
1 l
1 BOCKHOLD: If you said you had ninety degrees in 2- the summer time in that room and that room would never,
! 3 actually never rapidly fall to sixty degrees.
i 4 BURWINKLE: .The ISA standard was twenty -- how
~
5 many degrees below room temperature?
6 STOKES: Eighteen degrees.
7 BURWINKLE: Eighteen degrees. So we always are 8 going thirty, which is more than eighteen.
9 BOCKHOLD: Okay.. So we believed then we had 10 good air quality and a poor PM program in '88 and we fixed 11 'that. l 12 BURWINKLE: The PM program needs some minor 13 tuning up now.
14 KOCHERY: (Inaudible) minor tuning needs to be .
15 done now.
]
16 BOCKHOLD: Oh, yeah, I agree.
17 VOICE: (Inaudible).
18 BOCKHOLD: Oh, yeah, we flapped around with the 19 fact that we got a, you know, on the 29th or so we got a j 20 crummy reading and nobody knew about it until Milt Hunt picked 21 it up.
l 22 MOSBAUGH: George, we had a bad reading today.
23 Sixty degrees on the 2A diesel.
24 BOCKHOLD: The 2A diesel I think we're working 25 on the problem; isn't that right?
9 l
i l 1 STOKES: They had left the dryers off, I think 2 following the PM, both dryers off.
3 VOICE: (Inaudible).
4 HORTON: Haven't we got any good readings.
5 BOCKHOLD: Not on'2A, 2B (inaudible).
l 6 KOCHERY: 2A was high. They're trying to drain 7 down the tanks.
8 BOCKHOLD: I can doublecheck with operations and 9 we should be bleeding that tank down.
10 KOCHERY: Cotty's going to do that today.
11 BOCKHOLD: Okay. When I heard about it, and I 12 heard about it yesterday or so or the day before yesterday --
13 actually, I heard about it just before the meeting with the l
l 14 NRC.
15 He mention +d there was a possibility and they finally 16 took the reading and I got the information just before they 17 finally took the reading that if effective and I think it was 18 sixty degrees at that point.
19 I thought I told Skip or somebody in operations to go 20 ahead and start the bleed, feed and bleed on the tank too.
21 BURWINKLE: For PM program improvement, the PM
! 22 currently says to use a pressure regulator upstream of the 23 instrument and the instrument manual says that you should not 24 use a pressure regulator. It should be a needle valve. That l
l 25 needs to be changed.
10
l 1 STOKES: (Inaudible) that had'been changed in 2 every version of the PM a year ago. We put the correct 3 numbers in there and the correct procedure and they changed it 4 in the meantime. And I just dispositioned another DC to have l
5 me write another procedure. So the PM has been out of our 6 hands. As soon as I correct something they say redo it.
7 STOKES: (Inaudible).
l 8 KOCHERY: Also the dryers are out of service. !
9 They still run the compressors. I can't understand that.
t l l 10 BOCKHOLD: I'll write a note to Skip Kitchens 11 (inaudible). I don't understand why.
12 BURWINKLE: And the reading for (inaudible) the 13 reading at atmospheric pressure, they ought to convert the I
14 acceptance criteria at atmospheric pressure : and then they '
15 wouldn't have to go correct back to receiver pressure every 16 time they did it with, you know, chance for error and not 17 knowing how they do it.
18 KOCHERY: (Inaudible) make that error.
19 KOCHERY: (Inaudible).
20 KOCHERY: They give the readings and they get l 21 the temperature, you know. They just (inaudible).
22 VOICE: Yeah.
23 KOCHERY: And they go back to try to correct 24 that one --
11
._ . _ _ __ . - _ - . __ . _. . _ _ . ~ _ . _ _ _. _ _ _ _ - _ _ -
o
- 1 BURWINKLE: So we're going . to end up with an j
~
l 2 acceptance dewpoint of like minus five degrees or something l 1
j 3 atmosphere.
l 4 . STOKES: (Inaudible) are you saying.take out -
I 5 the charts and -- 1 l
6 . KOCHERY: That's right. )
l l
~7 BURWINKLE: Well, their procedure.doesn't tell 8 them how to correct it.
It just says to correct-it, so we 9 don't know how they're doing it.
10 STOKES: Yeah. I.just dispositioned a DC to 11 have them rewrite the field test procadure for each one of-l 12 those and make sure the (inaudible). i l

l 21 VOICE: Right.
l 22 VOICE: (Inaudible) or region number, what's 23 that number?
24 VOICE: (Inaudible) just got a message j
- l 25 (inaudible).
12 .
e -
1 MOSBAUGH: The conclusion that I can draw, 2 George, is that I think that we know we've had compressors i 3 that -- dryers out of servjce for a long period of time. .
! e 4 Kenny says that we have continued at times to run the ;
5 compressors even though the dryers are out of service, and I l 6 believe that when you do that, you have a condition like you ,
l 7 have right now on 2A and you'll end up with, you know, sixty 8 degree or so dewpoint, okay. !
9 And we have operated that way, okay, and I think there's 10 an operating history like that, and I think having operated l 11 that way in the past, you know, I don't think we can say we've 12 always met the statements on air quality that we have in the 13 FSAR.
I 14 On the other hana what we're saying is that we have 15 inspected the receiver and we've inspected the filters and 16 from the extent of that inspection, we have not detected a 17 corrosion problem, and I think that's about as much as we can 18 conclude.
19 BOCKHOLD: I think we can add that, you know, 20 the thirty degree dewpoint drop because of the way the 21 system's designed still gives us satisfactory air and its our 22 engineering judgment associated with that.
23 MOSBAUGH: I think you have an actual case right 24 hero now on 2A.
25 BOCKHOLD: That's sixty degrees (inaudible) --
26 BURWINKLE: -- dropped to thirty (inaudible).
13
1 BURWINKLE:- You would meet the requirements of; 2 sixty. degrees certainly.
3 BOCKHOLD: -- on 2A..
4 BURWINKLE: If you postulate the dryer.being out
~
5 for a long period of time in the summer and the room getting-6 to ninety -- I guess design maximum the room is like ninety-7 eight.
8- BOCKHOLD: You've got to look'cVer a. course of' 9 time,'too.1 10 BURWINKLE: Yeah.
11 BOCKHOLD: 'I mean, when you do the bubble test, 12 you're bubbling moist air down the line. You know, that's for 13 a short ' period - of time. You've got . saturated air going 14' through the control. That's what the manufacturer is using, l 15 but short periods of time.is not a problem.
16 BURWINKLE: Yeah.
17 BOCKHOLD: The problem is that you get water )
i 18 down the line and it sets there and corrodes.
19 BURWINKLE: And corrodes and'(inaudible). l 20 BOCKHOLD: That's a big problem.
21 BOCKHOLD: Okay.
