9 10 BOCKHOLD: We're going to come up with the most probable i 11 scenario. Okay, what caused the problem out there.

. 12 MOSBAUGH: Hopefully, we can come up with just the actual .

i 13 real right root cause.

14 BOCKHOLD: If we can come up with the actual real root i

15 cause, that would be wonderful. I don't think that's going to 16 happen, my gut reaction.

17 MOSBAUGH: Well, George, you know the NRC is going to i

18 write a NOREG on this.

19 BOCKHOLD: I understand.

20 MOSBAUGH: When you write a NUREG--

21 BOCKHOLD: If you don't have a probable cause--

23 MOSBAUGH: --you kind of need--you kind of need an actual 23 real root cause.

24 BOCKHOLD: I understand exactly, but I don't think its 35 going to happen. I think we're going to blame it on -- from what 36 I heard the expert say in that meeting in there is that we're going 27 to blame it on air leakage and one of the lube oil sensors being l 28 vented continuously-- 1 l

29 BOCKHOLD: -- and therefore, low air pressure gave some 30 spurious trips and there were three of them. Low-turbo lube oil 31 pressure, low jacket water pressure, and high jacket water 1

32 temperature is what the people say they saw come in on the engine i l

4 1 panel, okay. The thing -- the thing that to me is real important ,

2 is if we pin it on that, is there any way that we can measure by 3 installing a little flow meter, do we have too much leakage in the i

4 engines?

5 MOSBAUGH: Well, yeah.

6 BOCKHOLD: You know, so that needs to be the corrective .

7 action, and we need to kind of figure out how to do it along with

. 8 the, determining what the root cause is or at least look at that.

9 MOSBAUGH: Well, when you -- when you blame it on leakage, 10 okay, you're going to draw into this orifices. There's little >

11 bitty orifices that range from 6,000ths to 14,000ths, okay, in the ,

12 pneumatic logic. And you draw in cleanliness, in-line filters, 13 instrument air quality.

14 BOCKHOLD: NRC has asked specifically about air quality j 15 and I committed that we would go run a test to whatever standard 16 was that we were going to do it. And, I think Paul Kochery was j

17 [GPC: off) [NRC: offerred] to make that happen or at least Ken I l

i 18 Holmes tras in the meeting. I don't know who was in the particular l

19 lead to make that happen (inaudible).

20 MOSBAUGH: Okay.

BOCKHOLD: See the flavor is--NRC is chasing every loose 5 dangling end out there right now.

r 6 MOSBAUGH: Yeah. r 7 BOCKHOLD: And I'm concerned that come tomorrow, okay, ,

I

] 8 they're going to be more frustrated when we've done all the testing

. 9 and the engine's running great, you know.

10 MOSBAUGH: It certainly is frustrating when we can't find l

4 11 the root cause.

12 MOSBAUGH: Okay, so -- so what do you want specifically?

13 Figure out something to look at air leakage, (inaudible) leakage, 14 or --

15 BOCKHOLD: I -- I think the people involved, af ter they do 16 the testing, are going to need to say -- just not rub their hands i 17 and say, gee, we're done, okay.

18 MOSBAUGH: (Inaudible.)

'19 BOCKHOLD: I think -- 1 think tomorrow is the crisis day

! 30 in this thing. You know, so that's my concern is getting ready and 21 -- we need to talk to them.

22 MOSBAUGH: I'm not going to be here tomorrow, George.

4 23 BOCKHOLD: I know you're going to take some time off.

34 MOSBAUGH: I'm [GPC: driving to] [NRC: in] Cincinnati. I 25 am flying'back.
