10 MR. BSARD: I think that's fine.
11 A. I w4s sound asleep. At approximataly 1:40 12 in the morning, seems to me that's wnat the t im e was
() 13 on the clocx wnen the phone rang. Tna t's usually 14 wnat I do is I open my ayes and look at tha clocs 15 and think wnat did tney do now. I answered the 16 phona, and Tod Lehman, the chift supervisor, 17 informed me that the reactor nad trippad. And 13 following the reactor trip, the main steam isolation 19 valvas had gone snut,-and tna aux. faed pumps were 20 not running at the time.
21 Q. So you got tne information that the 22 ranctor tripped, the MSIVs were closed and the aux.
23 feed pumps ware.not running?

4 Q. Which is almost self-avidant?
5 A. ;4he n he told me tno MSIVs had gona shut, I 6 knew that.
7 Q. You xnew.
3 A. I aaxed him what tno subcooling margin was 9 and whether he nad indications of ovarhaating ut 10 that time. And he said he did not. HO said tnat he 11 nad operators on tne way to both the auxiliary read 12 pumps and tna start-up feed pamp to restart the aux.

15 I nung up the pnene. Called Louie Simon, 16 g the op supervisor, since he lives relatively close 17 to the plant, and he answered the phona. I said, la Louie, we've lost feedwater. The reactors trippud.
19 I want you to get there immediately. He said all 20 right. Hung up the phone.
21 I call 2d Steve Quennoz and told nim that 22 the reactor had tripped. We'd lost feedwater. That 23 I had Louie going in, and I'd call him back in just
,.s 24 a minute as-soon as I got back with the plant to'sce i i LJ ACE FEDERAL REPORTERS INC.

k /~ 2 get those guys out of oad and gat Louia on his way 3 in nare because I know Louis can maka it in, you 4 Know, 20 minutes or so. I then called tna plant 5 aack. This was probably rive minutus later at tne 6 most, maybe six minutes.
7 BY MR. BEARD:
3 Q. You got a direct number into the 9 supervisor's --
10 A. Yes, I can dial dir-act into the shift 11 supervisor or the control room. I called the 12 control room. There is a four digit numbar where I
()
13 can call the control room. It's not a public'numcar 14 or anything, but I callad into the control room.
15 At this timo Ted said -- I asned nim tor 16 plant conditions. I said what's subcooling-margin, 17 wnat's pressure, what's tamperature, and wners you 13 at. He told me subcooling margin was 90 dagroos.

11 Q. . And the start-up valve you're refarring to 12 would be the one that feeds trom the start-up pump?
b) -13 A. Yes, SP7V. He said he had reestablished 14 tlow to the No. 1 steam generator. I said do you 15 have anything on No. 2. He said No. 2 aux. food 16 pump is coming _up. I said, are you cooling yet? Ho 17 said wait a minute. And he --
there was some other 18 conversations. Ha set the pnono down for s second i 19 and cama back. And na said --

5 BY MR. BELL:
6 Q. Normal steam ganarator trips what, 1010 7 pounds?
8 A. 1010 to 1015 yes.
9 Q. And tnis steam generator pressure had 10 dropped from 1010, it's normal value, down to 970 il PSIG.
12 A. He told as that he had a safety valve blow
() 13 excessively on the trip. So, you Know, attribut3d 14 that to the safaty valve blow.
- 15 Q. You'didn't thinK the Jteam genarstors were 16 dry?
17 A. I Knew tne ATOG procedura says as long as la you'ra above '30 you're not conaidared dry. And I 19 saked him what the level was twice, and ne said --
4 20 the first time we talxod, ne said he still had --
it 21 seemed to ma like 15 or 20 inenos. The second time 22 ne said it was indicating about 10 or 12, but --
23 Q. Regardless-ot tne ATOG procedurcs, do you
,f s 24 personally tninn the steam gancrators ware dry?
( l us ACE FEDERAL REPORTERS I t1C .
(202) 347-3700 a
13 1 A. Do I personally thinK it was dry? I tninK gS
J 2 tnat we had bottled tne genarator up. There was 3 wa te r and steam pressure in ther3. And by the 4 tecnnical definition o t. dry, I don't think tney sere 5 dry.
6 Q. But only ona -- avan if there was 7 oxcessive lifting of tne aatety, tnat would effect 8 only one steam generator's pressure, right?
9 A. That's true.
10 Q. So what about the other steam genera tor ,
11 tho steam ganerator that the safety wasn't stuqn on?
12 A. Our safaties typically blow us down to 960,
() 13 930. And than we-recover them.
14 Q. But as soon as they seat, than the decay 15 haat and pump heat brings you back up to 1010, rignt?
16 A. Pretty rapidly.
17 Q. Closa?
18 A. Yes.
19 Q. And pretty tast?
20 A. Yes.
21 Q. So even on the steam ganarator --
22 A. In my mind, I tnink tnat we were probably 23 overheating at that particular time, but --
24 Q. So avon if you ware overheating and even
\m ACE. FEDERAL REPORTERS INC.
(202) 347-3700
14 1 if there was some small quantity or water in tharo, 2 it wasn't sutficient for decay neat removal?
3 A. Correct.
4 BY MR. BEARD:
5 Q. I'd like to understand better a concopt 6 term I'va neard mentioned out here a number of timas.
7 Maybe you can h21p me. It's the term you asked him 8 were you overhoating. Now, when you use that term, 9 what are you talking abou t?
4 10 A. What we maan is is the plant heating back 11 up. And at the first call, we weren't. We ware 12 still at, I'd thing it was, lixe 560 or something at I'l 13 the time, which, you Know, is loss than the normal V

\l 2 if he couldn't get the core cooling, to tall nim if 3 he don't get any faadwater cooling --
4 A. In one minute I told nim.
5 Q. -- to line up tn2 low pressure injection 6 to the nigh pressurs injection to gat a path ot 7 cooling water to-the core?
8 A. Yes. I told him, when I was on tne phone

9 and wa only had the sta r t-up pump on tnat second 10 phene call, I ordared him, I said in one minute if 11 you don't have cooling on the other steam ganerator, 12 'to lina up for make-up nigh pressure injaction I'i 13 cooling.
U 14 Q. You can't.hava adequate decay neat rcmoval 15 with Just ona steam ganerator?
16 A. With only the. start-up pump by itsalt, 17 according to the B&W topical raport with no other 13 cora cooling methoda, it seems to me'it was like a 19 titty-fitty chance by tneir probablistic risk 20 analysis that if we didn' t get it established in a 21 half an nour, we may not have enough in the start-up.
22 There was analysis we had B&W do after TMI 23 as an addendum since we don't nave the nignast pumpo,

4 And they analyzed these small breaxa with S caly feedwatar. cooling and not make-up cooling in 6 addition to it. And with only start-up pump cooling, 7 tnere's like a fifty-fifty chance on a certain siza 8 bre1x that you won't.make it betore -- before you 9 boil down enougn that you can gat high pressure 10 injaction in.

7 Steve said, you'ra rignt, we probably were.
3 He had an old set of them, ha said, an oldce sat of 9 bcoxa. But he said-tnay weran't up to data. And I 10 said even if wa ware, Louias going to b2 at tha 11 plant in about tan more minutes, and I'm going to be 12 there in about 20 more minutes, so we can sort that

20 Q. SFAS is ESF actuation on low. pressure?
21 A. On low reactor coolant pressure due to the 22 overcooling you get. By.our procedure you have to l

l 39 1 time away from this shift supervisor, so the two
'q' O 2 aspects.
3 A. The plant.was stable at this point. The 4 five minutes it took Ted and Louie to tell me where S we were at I don't feel took t i de.:.a w a y"ef r o m the
-6 snitt supervisor at that point.
7' Q. I'm not criticizing. I just want to 8 understand what was involved.
9 A. What was involved in the turnover?
10 Q. Yes.
11 A. Just basically where we were now. They 12 told me the status of the aux. feed pumps, the fact l
() 13 that No. l-was running on the trip throttle valve in 14 manual control. No. 2 was the pistol grip was in 15 manual, and they were controlling the speed from the 16 control room, not in auto essential control.
17 They told me the start-up feed pump was on, la feeding steam No. 1 generators, and the levels were 19 being controlled j ust fine. We looked at the 20 primary plant parameters. Pressurizer level at that 21 time was a little high. It was up over 200 inches 22 if I remember right. But pressure and'everything 23 was normal.

, I would be down around 100 inches, but they had i
- I 2 injected acid and water from the BWST to complete 3 their boration, so -- and did not let that-water 4 ~ down. They kept the inventory in the sys tem. So 4
5 the pressurizer level was a little high, but that 6 was to be expected. Like I said, the entire 7 briefing probably took me five to six minutes at the 8 most.
9 Q. To what extent were you giving directives 10 f or opera tion of the plant or systems or people?
11 A. I was given no direction -- I was not j
12 giving any direction to the operators at this point.
() 13 Anything that we needed done by the operators, you 14 know, we'd -- I'd say, Ted, we need to check on this.

to see where I was.
( 21 Q.- Getting back to the DAD system, you wanted 22 to see where you had been7 - -

3 You can't tell in that ten minute time frame where 4 the plant had been because the strip charts move so l 5 slow that they just draw all over each otner and all i
6 .you see is lines take over the whole range.
- 7 Q. Your plant design didn't include a feature 8 on auto trip or ESF evacuation that it slows the i
9 recorders down?
10 A. No, sir. I called Don Lee a couple 11 minutes -- well, as soon as I hung up from Jacque 12 and told him that I needed maintenance support in
() 13 all areas. In other words, I wanted pipe, mechanics, 14 and electricians and INC in addition to the people 15 that we had on site.

7 Q. Is your plant manager on site now?
8 A. He arrived -- I've.got his time too. He 9 arrived at 3:13, right about now. He' walked in the I
10 control room. I was just finishing up tnose calls 11 when he walked in. Dick Crouse, vice president 12 nuclear, came in about 3:04 according to the

16 Q. Is it getting' crowded up there?
17 A. Not really. They stayed back out of the 18 way. They didn't get up in front of the panels or 19 anything. Dick just stayed back in the back and i
20 asked if he could do anything as far as getting 21 anybody else out. I just informed him I called 22 everybody I needed right now. They were all on 23 their way in.
24 He wanted an update on the plant, and I ACE FEDBRAL REPORTERS INC.

19 a half a Baby Ruth candy'bar in his mouth.and, you !

4 They were standing -- well, Brian had to 5 stay at the panel or one of them with the aux. feed 6 manual, but they were all just back and forth down 7 the panel, so they were -- they still had a lot of 8 adrenaline being pumped. But there was a little bit 9 of a -- you could tell they seemed more relaxed.

18 So we knew that within a few minutes, we

5 Q. So again could we say that.the tech 6 support center as a organizational entity had a 7 degree of fermality or degree of involvement of 8 people that were not needed in this event, that that 9 was not of use to you?
10 A. It was not of use to ma to have all the ,
11 extra people. The people that I needed to get all 12 the data out were the tech -- was the toch section,

17 A. The way our procedure is, it's essentially 18 all or nothing.

5 Walt Rogers had showed up at this time, 4
6 and Don Kosloff are our two irspectors, and they 7 wanted an update as they came into the control room.
8 So I spent some time with them and explained what 9 went one where we were now, what we were doing.
10 And I also discussed with Walt the fact 11 that by our emergency action levels for that ten 12 minute time frame, literally we were.in a site emergency during that time. And that we did not
(]) 13 14 declare a site emergency because by the time we got 15 into the EALs when it's all over, we were out of it.
16 We had normal feedwater cooling.
17 And he said he didn't expect us to go 18 declare a site emergency, then undeclare it. He 19 said he felt that at the time what we had done.was 20 fine. We had all the people we needed.

4 In other words, I was just checking over 5 to make sure that the -- somebody had all the log o sheets there, that the trip recovery procedure was 7 being signed. Kind of an administrative overview to 8 make sure tnat nobody had anytning that fell in a 9 crack that we might have missed.
10 And Steve and I were discussing whether we 11- should. downgrade from an unusual event at this time.
12 It was about 4 in the morning. And I said I didn't
() 13 want to downgrade from the unusual event until I was 14 confident that we had vacuum back, we had turbine 15 bypasses steaming to the condenser. In other words, 16 we'd restored the entire secondary side and gotten 17 off the atmospheric vents and aux. feedwater.
18 So even when I got the . boiler: back, vacuum 19 back and all of that which was later on in the 20 -morning, we let it sit like that for several hours 21 to ensure that we were able to maintain it. Then we 22 ' downgraded from the unusual event. So there was a

I don't remember the exact time we 8 downgraded right off the top of my head, but seems 9 to me it was like six hours later; is that right?

21 So I, you know, I did maintain us in an 22 unusual event probably longer than necessary, but I 23 felt it was needed due to where we, you Know, what 24 we had been through over the night. I was probably

~6 A. The decisio.n to go to mode 5 was made by --
7 we had a -- geez, I'm trying to remember whether it 8 was a full SRB. Later on in the afternoon, on 9 Sunday afternoon, we met with --
Steve Quennoz was 10 there, Jacque Lingenfelter. Steve had been in 11 contact with -- well, Dick Crouse was there. I'm
-12 trying to get all the players that-were present.
13
(]) There was other people there, but I can't --
I can't 14 .get all the phases.
15 And we discussed a lot of' things, one of 16 them being if we immediately go off to mode 5, we 17 can't do any testing because we won't have vacuum 18 and steam available'for the main feed pumps. We 19 won't have steam available for the aux. feed pumps.
20 -I kept saying, yeah, but, we've been here.
21- We're not really -- we'd already declared one aux.
22 feed pump inoperable because of the fact that we
-23 .couldn' t get control of it- at all. The.other~ aux.
24 feed pump was shaky at best. In other words, not --

~
'S comfortable sitting there in tne situation we were 6 in, and I wanted to go to mode 5 immediately. But, 7 like I say, there was about an hour's worth of 8 ' discussion there over it. We tried to weigh all the 9 pros and cons where wa wouldn't be able to 10 troubleshoot anything and all these.
11 But I said, yeah, and also we just had a 12 pretty bad event, and we're_not sure what caused any
() 13 of this stuff. If we sit in mode 5, nobody will get 14 on our. case. Where if we sit in mode 3, we're 15 liable to get much' more than a quarter back.

ACE. FEDERAL REPORTERS INC.
(202) 347-3700
1 60 1 Did you enter any sort of action s ta temen ts that
/~T kl 2 would cause you to have to go to mode 57 3 A. There was nothing at the time since we had 4 only declared aux. feed train 1 inoperable. Had I 5 declared aux. train,2 inoperable, that would have 6 been six hours to mode 4, twelve hours the rest of 7 the way to 5.
8 .Q. So it was pretty close.
9 A. And that was --
I wasn't comfortable 10 calling it officially operable. It was doing its 11 safety function. It was running just fine pumping 12 water in manual No. 2. And doing a normal cool down is much better than doing a crash down where you
(]) 13 14 have to run the RCPs all the way'down where we don't 15 normally do that.
16 We natural circuit rather-than degrade our 17 seals. In other words, we take the pumps down.
18 When we get down to -- I forget the exact. pressure 19 and temperature -- we turn:them'off and natural pump 20 the loope and just maintain the decay, and so.we 21 don't. form bubbles in our hot lakes.

5 Q. So the final -- we heard some discussion 6 before we left at the. office, the final outcome at 7 the plant was'the decision was made to go a'. the 8 way to' cold shut down rather than stay in some 9 higher mode and do testing?

23 after we had vacuum back, we had the s ta r t-up feed i i

5 Now, what this test involves is putting 6 the auxiliary feed pump in its normal emergency 7 standby status except for the valve that feeds the 8 steam generator, the 3869 or 3872, the one that's 9 No. 1 aux. feed pump-to No. 1 steam generator.

15 -A. Yes.
16 Q. And you say that it not only came up to 17 proper speed and discharge pressure, but it 18 controlled all right?
19 A. When you say control in this mode, it 20 doesn't know what level t'o control. It-just comes.
21 up and stays on the high speed atop because the 22 circuit breaker that you open for that valve is what 23 tells'it what steam generator level to-control. So

2 as fast as you can get there. .
3 Q. Okay. But I guess what I'm really trying 4 to understand is that you passed the test?
5 A. Yes.
6 Q. But it still didn't really show that the 7 equipment was functional in the way that it normally 8 does and the way you'd like to see it?
9 A. True. It was not intended to run this 10 tast and declare the pumps operable.
11 Q. I'm not questioning that. I really have 12 in the back of my mind a thought of the ~ adequacy of
.() 13 the test itself.
14 A. We only_ran one-phase of this test. This 15 test nas many phases. All I was trying toJdo was 16 see if I could duplicate.that super feed trip.- In 17 other words, we ran a:section of-this-test.: This is 18 about this thick.- It's about this thick.
19 Q. That's about two inches thick.
=20 A. And there's many,: many' phases to this test.
21 We ran the phase that gives the pump a start signal 22 and just measures the response time from stopped to 23 disch'arge pressure required by the tech specs, which 24 'is only one phase of this test. And all,I was --
ACE FEDERAL REPORTERS INC.
'(202) 347-3700
67 1 that's -- this particular test is the easiest way O 2 for me to see if the auxiliary feed pump can start, 3 get up to speed and not trip.
4 Q. Okay.
5 A. In other words, I didn't want to have to 6 write a special addendum to the operating procedure.
7 I knew that this test existed. And I said, let's 8 just run section 6 of the refueling test as a quick 9 and dirty method to see if we can make that aux.
10 feed pump trip again.
11 Q. Okay.
12 A. We wanted to see what its control was. We
() 13 also wa n ted to get some confidence in No. 2, since 14 we had not officially declared it inoperable. We 15 wanted to say, yean, No. 2 aux. feed pumps are right 16 in its present condition, so that we don't have to 17 enter.an action statement on-loss of both trains and 18 have to do a six hour cooldown.

10 Q. During any time in the event, did you have 11 to install any electrical jumpers to get equipment 12 to operate correctly?
() 13 .A. Not that I'm aware of.
14 Q. All right, sir. We were told earlier this 15 morning that the turbine bypass valve failed because 16 a portion of the main steam header had baen-filled 17 witn desuperheating spray from the feed system, I 18 think, the gentleman told us. However, that seems --
19 seems to be a little funny since both feed pumps 20 were tripped. He mentioned values of1100 pounds 21 per square inch. And you had no pumps operable 22 that has that high of a discharge pressure.
23 A. Start-up feed pump was running. .As soon s 24 as the start-up feed. pump was running, the system ACE FEDERAL REPORTERS INC.
(202) 347-3700
70 1 depressurized. The desuperheating valve control 2 was -- the automatic portion was out of service, and 3 it was being controlled on a bypass valve.
4 Q. Yes, we got that part. Okay. I inferred 5 that. I don' t think I'll take this any further.
6 I'd forgotton about that start-up of the start-up 7 feed pump. Do you think if the operators had the 8 SPDS display available, it would have been easier 9 for them to ascertain plant conditions?
10 A. Yes, sir, very much so. I don't think 11 that they had any trouble ascertaining what they 12 were in. But the SPDS is a great machine when it's J 13 working.
14 Q. I would think that you'd want that 15 operable at all times or as a high availability as 16 possible not only because your operators are trained 17 on that at tne B&W simulators, but is it not also 18 listed in your emergency procedures?
19 A. Yes.
20 Q. The pressure regulator on the discharge of 21 the feed pump oil pumps that supplies control oil 22 pressure, if that valve did not move quickly enough 23 on a feed --

15 From the information I think we've heard,-the 16 operator, for seat of the pants reasons or whatever i-17 -other reasons, he elected to close the block valve.
la He didn't like the way things were going apparently.
19 Okay. And then I understand' subsequently'.the valve 20 appears.to have been closed, the ;PORV was closed.
'21
- And then the block valve was reo'ened p later.

l- ~1 or this--- I'm calling for an assessment on your b 2- part as to whether it misbehaved during this. event? '
L t-j 3 A.- Looking at the data, it appears that on j
'4 the: third lift it may not have. closed as rapidly as 5 it should have. In other words, it was not the same f
i i 6 as the first two lifts. ' There may'have been other i
j 7 thing s .' tha t ,en te red into that though. They were a L :
l 8 little hotter at the time.' .In.other words, there
!. 9 was probably a-little more energy being put in. The 10 PORV may have, you"know, stayed open for that reason.
11 It still should have closed when 'the 4
12 pressure' dropped below 2350, you know, on-its normal 13 reset. set point. I'still, not having all the

5 Following that, when the PORV block valve 6 was closed, the PORV apparently was believed to 7 have closed, and I'm not sure the source of that 8 information, but at least it was believed to have 9 closed. And then it -- somebody made the decision 10 to reopen the block valve.
