s l 1 j SINCLAIR: The following interview is being conducted of Mr. Kenneth 24 l Bryan. Mr. Bryan is the Shift Supervisor at the Three Mile Island Nuclear Power Facility. Present time is 3:18 p.m. Eastern Daylight 4' l Time. Today's date is May 16, 1979. The place of the interview is t 5 trailer 203' which is located immediately outside the south gate at the 6l Three Mile Island site. The individuals present for the interview will i I be, interviewer Mr. Dorwin R. Hunter. Mr. Hunter is an Inspection 8 Specialist, Performance Appraisal Branch, I&E Reactor Construction 9 Inspection. Also attending the interview will be Miss Tracy Binion, 10I Inspector Auditor from the Office of Inspector and Auditor, U.S. Nuclear l ll! Regulatory Commission. Also attending is Mr. Chip Foster. Mr. Foster 1 12l is also an Inspector Auditor, Office of Inspector and Auditor. My name i 13 is John R. Sinclair. I'm an Investigator, Office of Inspector and 14i Auditor, U.S. Nuclear Regulatory Commission. Prior to the interview 15-being conducted, Mr. Bryan was provided a copy of a document explaining 16! his rights concerning information to be obtained reg 7rding the incident 17 at Three Mile Island. In addition, Mr. Bryan was apprised of the purpose 18 of the investigation, its scope and the authority by which Congress , 19I authorizes the Nuclear Regulatory Commission to conduct the investigation. 20! On the second page of the advisement document, Mr. Bryan has answered 21l three questions. The questions and Mr. Bryan's replies will now be 22 recorded as part of the interview. 23 24\\ 25[ r ry ? ,jg i, boJ l

a i l 2 1f SINCLAIR: Mr. Bryan, do you understand the document? 2: l 3! BRYAN: Yes I do. 4l i 5 l SINCLAIR: Second question. Do we have your permission to tape the 6' interview? 7 i 8 BRYAN: Yes. 9! 10 S_INCLAIR: Third question. Do you want a copy of the tape and transcript? 11l l 12! BRYAN: Yes. I 131 14 SINCLAIR-Okay, thank you. Okay, at this point I would like you to 15i provide us maybe a brief w3rk history, work in the nuclear industry and 16! any training which may be pertinent. 17! i 18j BRYAN: Well, I started work with Metropolitan Edison Company at Crawford 191 Station in Middletown, coal power plant, and I came down here in 1969 in 20l the training program Met Ed had set up for control room operators and it 21 was in a 42 week course and that's basically how I got into the industry. 22i We went through the 42 week training course that Met Ed has supplied and I 23! from there I went on to get my R0 license. I 24! 25! s e [Q? \\* t l UU J r

I i 3 { It ? SINCLAIR: R0 is? 2f I BRYAN: Reactor Operator. 41 i 5 SINCLAJ: Reactor Ooerator. And all your time you spent here at Three 6i Mile Island? 7, 8 BRYAN: Yes, all my time has been at Three Mile Island. 9l [ 10f SINCLAIR: Okay, thank you. At this point I'll turn it over to Mr. I 11l Hunter. I 12t 13 HUNTER: Okay, Ken after the 42 week training course you then received 14i your reactor operator's license and you are a control room operator in i 15i which unit? 16I l 17 BRYAN: Unit 1. 18l 19! HUNTER: Ana then you were promoted to Shift Supervisor from a Control 20i Room Operator? 21 22 BRYAN: No, my second position was a Shift Foreman in Unit 1. 23 24! 25f ,0 u, s

{ 4 ) l,; 'j HUNTER: And then? 2! 3! 1 BRYAN: And then Shift Supervisor. 4j Si j HUNTER: When did you obtain the position of Shift Supervisor in Unit l? 6j 7 BRYAN: Station Shift Supervisor. Approximately a year ago. 8 9 HUNTER: And in that position you are...you have a senior license on 10 both Units 1 and 2? 11l i 12l BRYAN: Yes sir. 13 14! HUNTER: Okay. Okay, Ken, realizing that it's been a while since March i 15! 28, the March 28, you were working the 11:00 to 7:00 shift on Unit 1, if 16 I understand your position at that time. 17! 18! BRYAN: That's correct. 19! 20! HUNTER: And that would put you onsite somewhere right...right prior to } 21 11:00 on the 27th. What was the...what were your duties on Unit 1 at 22, that time on the 11:00 to 7 what were you...what were you involvec in in 23 Unit l? 24 25; l ,ea Ib7 '{ k i d buJ [

{ 5 1 i BRYAN: We were in the process of heating Unit I up. This is...we just 2l finished refueling outage, we were heating Unit 1 up to put it back on l the line. 4j l c HUNTER: Were you doing any special testing, Ken? 6 I BRYAN: Not that I recall. Si 9! HUNTER: Just a..it was a normal heat up, normal procedures? I 10' 11! BRYAN: Yes. 12 13 HUNTER: What was the...what was your plan for the morning of the 28th 14! on Unit 1, just continue heat up? l 15 16i BRYAN: I. .I don't remember if we had done the second vent on the i 17li control re ' drives or not, you know, I really don't remember. i 18! 19! HUNTER: Okay, then... l 20i 21. BRYAN: I think we were the whole way up. 22 23' 24l 25j l /n7 iO' l OUJ iVi i

f 6 l! i, HUNTER: Alright. 2' I. 31 BRYAN: It seems to me like we were getting ready to...there...there was 4' something holding us up in deborating and I... I don't remember what it was. 6i 7 HUNTER: Okay, it's alright. And early in the morning apparently you 8 received a called from Bill Zewe on Unit 2, the Shift Supervisor on Unit 9 2. Can you characterize that particular call that you had from Bill? \\ 10j 11 BRYAN: No, I didn i get a call from Bill, I called Bill. 12 13 HUNTER: Okay. 14! 15i BRYAN: They announced over the page system that the turbine had tripped 16{ in Unit 2 and at i.ne time we needed st. , we were using Unit 2 steam 17! for feedwater heating and turbine seals in Unit 1, and I called him to 181 find out if the reactor had tripped and whether we needed our aux boilers 19! or not and he said that it did and he said why don't you come on down 20f and give me a hand and that's when I went down. 21l 22 HUNTER: Did he indicate to you anything other than a reactor trip, i 23l turbine trip? Can you give me any kind of point status at that time? 24i 25j t j f5 9 () O. \\ a l-U J

7 1 j BRYAN: He mentioned that he had ES injection already. 2! l 3 HUNTER: Does that mean anything to you as far as...was that unusual on 4j Unit 2? Sl I 6 BRYAN: It has happened before in Unit 2 on a turbine trip. 7l 8 HUNTER: Okay. About what time then did you get to Unit 2? 9l l 10' BRYAN: 4:08. 11! 12 HUNTER. Your fairly specific as far as your time how did you know I 13 exactly when you got there? t 14! 15; BRYAN: Cause it was right after I got there, but when I got there I 16! noticed that the feedwater valve...we weren't getting any feedwater to 17 the steam generators and Craig was standing in front of me. He looked 18! down and said the 12's are shut and he opened the feedwater valves. 19! 20f HUNTER: Okay. 1 21; i 22! BRYAN: .that's right when I got there. 1 23j 24l 25! I .c ~ i

8 lt { HUNTER: Ken, and when you walked into the control room, what keyed you to say your not getting any feedwater, what did you look at? 3l l 4! BRYAN: The first thing I noticed when I walked in was the Tavg indicator i and was 592 degrees, 596, and it was a little hot and I looked over the 61 steam generators and the levels were low and I said you don't have any 7 feedwater. 8 9 HUNTER: Did you notice anything other ther the Tavg in the fact that 10 the levels were...but were they actually at 10 inches or were they that 11 low, do you recall? 12; 1 13l BRYAN: They were that...they were low. 14! 15 HUNTER: They were low, they were very low. 16l i 17 BRYAN: Yes. 18j 19! HUNTER: Okay. Was there anything else that you noticed, did you notice 20 anything about the auxiliary feedwater, the emergency feedwater pumps at 21; that time or was that just your comment? l 22' 23 BRYAN: That was my comment at the time. That all happened right away. 24l I looked at Tavg, I looked at the steam generator levels and I said you 25i l l 07 inf bdJ iV i

9 l' -{ don't have any feedwater and Craig was standing between me and the 12 2' j valves, well he was right in front of them, and he looked down and said 31 the 12 valves are closed, and he opened them up. 41 5 HUNTER: Okay. Did the...did...were you then...were you two fellas then 0 or everybody in the control room, were you aware of the feeding of the 7 steam generators at that time and if you were how did you know when he 8 opened the 12 valves? i 9 10[ BRYAN: Well the levels started to come back. i lli i 12 HUNTER: Okay. Does that take time or does it occur right away? 13 14j BRYAN: It takes some time, yeah, we're talking a minute or two I guess. 15, 16j HUNTER: Alright, Craig mentioned something about the..the noise monitor 17l being on the A generator and that there was... i 18l 19' BRYAN: You could hear the feedwater. 20l l 21l HUNTER: . water hammer, splash in...in.. 22 23 24 25! 6 r t, [', ?03 \\c-l

l f 10 i i 1! BRYAN: Yes. 2! l 3 HUNTER: ...and the water entered the steam generator, do you recall 4 hearing that? 5 Gl BRYAN: Yes, that's the first I've heard of that since that night, but I 7 do remember it, we could hear something on the steam generator and we 8 assumed it was the feedwater. 9 10) HUNTER: Okay, did...did...what... did you wal k over and look at the i 11 feedwater station at that time? In other words to backup Craig or see 12 what he was doing, look at the feedpump pressures or are there actual, i 13] number of feedpumps running, anything...anything specific that you did 14 when they took.. opened the 12 valves backup? t 15; l 16! BRYAN: No, I...I think...the next thing I went over to look at was the i 17! pressurizer level. 18 19 HUNTER: Okay, lets... 20! 2 BRYAN: I was still...it was either that or the condensate pumps because 22 he didn't have..it seems to me there was only one condensate pump 23 running at the time or something. So I'd just walked in and I was just 2 trying to take a look and see what else is going on so I didn't pay too 25[ much more attention to the feedwater at that time. i o 3 / () 'g L' hd f

l 11 { l HUNTER: Okay, Tavg was high? No feedwater flow, they got the feedwater 2t i flow back, the 12 valves were closed and now they are open, the next M9 thing you indicate you throttled it up to pressurizer level do you I 4{ remember what...what it was at the time you looked at it? SI l 6I BRYAN: It was either still pegged high or just barely starting to 7 come.. come off the top of the scale. 8 9! HUNTER: Did that strike you as being unusual? 10! 11 BRYAN: Oh yes! Well.. 12! 13 HUNTER: Looking back at your training, but go ahead... 14! 15: BRYAN: With that high Tavg, I guess it..you know..you could expect a 16' higher than normal level. 17l t 18! HUNTER: Okay, Tavg should have come down to about 545 oc so and it was 19! 50 degrees higher, 40 something degrees higher rather, being at 592, 20lr okay. When you saw the high pressurizer level what was your..what was 21! your reaction then and what did you look at? I 22' 23 BRYAN: I looked at letdown flow and we were...there was a guy on...he 24 was trying to control letdown flow, increase letdown flow and reduce the 25l pressuri:.r level. O ? ,(,] ) ([i I I P

12 i !l' { HUNTER: Okay, and the.. if my notes ag'in are right, 8 minutes into 9t'i the event, apparently Ed Frederick was at the...at the pressurizer level 1 panel and also it could've been Fred Scheimann also was there. 4l 5 BRYAN: I think Fred was there when I... 7 HUNTER: Okay. 8 i 9 BRYAN: ...I remember Fred being there. 10i l 11l HUNTER: Alright, and he was trying to increase letdown flow? What 12I about the actual makeup flow, the pressurizer level is high, the 17 13 valve which is the makeup valve would be closed... i 14! t 15: BRYAN: Right. 16: 17 HUNTER: if it's fixed on automatic and I assume that it was, tilat's 18l the indication we're getting. What about any makeup flow through the 191 high pressure injection path or the reactor coolant pump seals? 20! I 21j BRYAN: Well you still have seal injection flow... 22 23 HUNTER: Would the operators ever secure the seal water injection flow 24l that you' re aware of? Would that be normal? i 25! 7 'Cl j () (U J IU I

13 li BRYAN: Would they secure it? ) 2 l 3' l HUNTER: Or have they...or would they routinely secure it or do they 4'l ever secure it or.. 5 61 BRYAN: No, that's not a normal... 7 8 HUNTER: ...and the procedures they normally keep the seal injection 9 operating? 10l i 11l BRYAN: Yes, yes. I 12l l 13l HUNTER: Okay. Well then you assume that..or did you notice whether 14 there was one or two makeup pumps on to make any seal water injection? 15i 16! BRYAN: I thought at the time that there wasn' t any on. 17 ( t, 18! HUNTER: I've been reading some ' the things. I want to make sure 19! because I'm cetting some different information and I want to make sure 20! that...can you tell me why you maybe thought that, or maybe..maybe they 21;i weren't off. That's what I need to know? 22 23 24i l 25I \\ 7 i O9 t

{ 14 l !l! i BRYAN: Maybe they weren' t, it's true. Ju l HUNTER: Yes, that's what I want to make sure. 4 1 5 BRYAN: I don't know how I came across this opinion but that morning I 6 assumed that they were off with the high pressurizer level and increase 7 " letdown and I thought we had secured them because of the fact that we 8 had a solid system and you didn't want to keep the head of the makeup 9I pump on the reactor coolant system. i 10 11! HUNTER: I understand. ) 12l t 13 BRYAN: But I just...just yesterday I was talking about it and I.. 14; they say there was one running yet, I don't know. 15! 16l HUNTER: Okay, fine. The..as they shift...as the..looking at your 17l' shift Unit 1, or Unit 2, and again looking at the seal water injection, ld! would the operators normally keep it on to protect the pumps? Will the 19! pumps run without seal water injection? 20l I 21! BRYAN: Oh, yeah. 22 23 24 25! f r 7 i' f g 'J U1 i

15 l 1 HUNTER: Is..,is it detrimental to the pumps at all? i 6 2; I I BRYAN: No, you can run without seal injection. 4l 5 HUNTER: Okay, so the reactor coolant pumps could run... 6l l 7l BRYAN: Yeah. 8 9{ HUNTER: ...your leakage then would just be out not being supplied by 10 the seal water injection? 1 11 i 12! BRYAN: True. I 13! 4 1 14i HUNTER: Okay. An item that I wanted to look at is that...early on you 15i indicated in a previous interview that, there's some previous information 16 that we have is tnat the...in previous interviews that we've done that 17l the core flood tank valves were closed or were closed while you were i 18l there. 19 20t BRYAN: Yes. 21 I HUNTER: Can you elaborate on closing those valves and what the..your 22 23 philosophy or your..the reason for those valves being closed if you 24 were involved? l l 25i ro, \\Qi uuJ l [

16 i i 11 BRYAN: Yes, we had, pressuri:er level was still high and core flood 2! j system is designed for a loss of coolant accident to reflood the..the 31 core and with the full pressurizer we didn't need any more water at the i 41 time we thought, so we closed the... isolation valves in the core flood 5 tanks. 6l HUNTER: Procedure for closing those valves or how..how...how did you go 0 about closing them? Do you have to go unlock them and energize the 9 breakers and then close the valves? Is that the way they were set up? 10i l 11' BRYAN: Yep. 12 t i 13 HUNTER: Who...who unlocked the valves? Do you recall who..who..did 141 you send somebody down or did Bill Zewe send somebody down? 15! 16i BRYAN: I don't know. I 17l 181 ':UNTER: Okay. 19t 20l BRYAN: Somehow or another by the time we got to that, the valves were 21[ energized I don't know... 22l 1 23l HUNTER: Okay. When you close them..close them, do you leave them i 24{ closed, I mean do you leave the electrical breakers closed, and were 25! they sitting there in the energizeo position? jh f} l- \\

17 ill BRYAN: Yes, so that it can be reopened. 2. 3 HUNTER: Okay. Reopened how? Manually, with a switch? 4 5 BRYAN: With a switch from the control room. 6l 1 7 HUNTER: What about any automatic opening of those valves? O 9l BRYAN: There is none. 10 11l HUNTER: The ES does not open those valves? 12 13 BRYAN: No. 14! 15 HUNTER: Okay. Later on in the day those were reopened? 16 i 17! BRYAN:

Yes, 18!

19! HUNTER: Well, did you happen to be there when they were reopened? 20! 21 BRYAN: No. 22 23 HUNTER: Okay. Did you happen to look at the steam generator, the 2d! condensate pumps were secured, the atmospheric dumps are automatically 25l Q t. i-

l ) 18 1 labeled but woen the condensate system is...no... the circ water pumps 2' were still on so the atmcspheric dumps were not in operation, the turbine 3t i bypass was in operation. Did you happen to look at the turbine bypass 41 valves and...at that time and if they were functioning or were on automatic? 5l l 61 BRYAN: I didn't look at those, I looked at header pressure and heder 7 pressure was holding. 8 9 HUNTER: Holding steady? 10i l ll! BRYAN: Yes and ir.iicating that the valves were working properly. I 12l 13 HUNTER: It looked normal to you... 14I 15i BRYAN: Right. 16! I 17! HUNTER: .then at that time? Okay. There seemed to be a problem with i 18! hotwell level and it was fairly soon after you got to Unit 2, Bill Zewe 19! ended up going to the Turbine Building and looking at hotwell level, can 20 you elaborate about the hotwell level and what the problem is with 21 hotwell level at that time? 22 23 BRYAN: We had a high indication in the (antrol room and Bill went down 24j to check the site glass and he came back and said, "The site..,it was 25! s0, r D 7 \\ d s b I

I l l [ 19 1 out at the top of the site glass" indicating that actually had a high 2 level in the hotwell and I think that's about the time we secured the 31 circ water pumps to automatically go over to the atmospheric relief 4 valves so that the steam we were dumping back to the hotwell would go 5 a'it the atmospherics and start reducing our inventory of water in the 6{ hotwell. I 71 8 HUNTER: The intent at that time was to get the condensate pump back or 9 booster pump and get 'e reject system back in and reject the hotwell 10 back to the steam generators. 11! 12 BRYAN: Capacity, yeah, well at that time we opened the. we wanted the 13! atmospherics opened, it was just so we'd be blowing steam out instead of 14 saving it, thus reducing the water inventory that we had in the hotwell. 15: 16! HUNTER: Okay. Do you know what the problem was with the hotwell? t 17! 18! BRYAN: The more I think back on it we didn't..we weren't feeding 19l anything, everything just ended up in the hotwell. 20[ l 21; HUNTER: That..that would be your evaluation of it now by just by again 22 looking back at it? 23 1 24l 25l f N UuJ l i

i l i 20 f 1! BRYAN: Yeah. 2. I, 31 j HUNTER: You weren't involved in getting it squared away and finding out 41' what was wrong with it, if it would'have a failed level control system 5 or... or whatever? 6 I 7' BRYAN: Oh no. 8 9 HUNTER: Okay. The.. throuch some inter.. of the interviews I've 10 come across in the fact that the reject line off of the condensate 11 system, the downstream valve on the reject line on Unit 2 is normally 12 throttled. Are you aware of that, or are you aware of the problem? Is 131 that for a specific reason? 14! l 15., B_RYAN: Yes, the automatic control valve sometimes fails open. 16l 17l HUNTER: What's the result if it fails open then? 18j 191 BRYAN: Get a low...a low suction pressure to the feed pumps and the 20[ feed pumps trip. 21f f 22l HUNT F.R: And low feed oumps tripped and then would cause a run back or a i 23l Unit trip? 24j 25! u- ,I

l { 21 BRYAN: Yep. i 2; I HUNTER: Okay. Is that thing going on for a substantial amount of time, 4 that you're aware of? 5 l 6l BRYAN: All I can say is that I know it's happened twice. 7 8 HUNTER: And the valves have teen throttled.... 9l [ 10' BRYAN: Since then to... 11: 1 12l HUNTER: Okay. 13 14 BRYAN: ..,to prevent that. 15j i 16! HUNTER: Al right. Were you involved at all in the demineralizer problem 17 in Unit 2, other than just discussions with the other fellows? IS! 19j BRYAN: No. 20l 21! HUNTER: ...because that ended up being the problem that they had, okay. 22! Were you ever involved in any of the trips in Unit 2? A turbine trip f 23[ before from any source? Personally, you know you'd have...you'd have 24j the... 25i v, i

I t I l 22 l ll' BRYAN: Yes. 2! t i 3\\ l HUNTER: ...you'd happen to have the... 4l P 5 BRYAN: I've been there for a couple other... I was... I'm just trying 6 to think... 7 8l HUNTER: Let me go a little further, Ken. During the trip that you had I that you have seen... if you have seen a trip, have you seen the ES 10 initiated before on a routine or a normal plant trip in Unit 2? 11l l 12! BRYAN: No, not while I was there. 13 14 HUNTER: Not while you were there, okay. But again you said it didn't 15 surprise you that it had initiated because you..had you reviewed trip 16i reports from the other trips that showed that ES had in fact initiated? i 17! l 181 BRYAN: I can't say that I 6ctually reviewed a trip report it just...we l$l all talk.. 20l 21[ HUNTER: Okay. 1 22l 23l 24i i 25i i I 3 ri c) to: !) * - I

f f ( 23 [ ll BRYAN: ... if a trip or something happens. 2, l 3lt HUNYER: Supervisors or other people, the operators had talked and you 41 were aware that that was the problem, okay? How did you feel about r 5l l pressurizer being solid, personally, and you look... look back at your 61 training, does that...did that...did your training key on trying to 7 maintain a pressurizer other than solid? 8 o BRYAN: Oh yes, yes, we tried not...we tried to maintain it with a ld! bubble. I 11! 12 HUNTER: Can you give...give me a feeling of...of what the problems t i 13l you...you would have visualized with allowing the pressurizer to go i 14!' solid? 15; 16! BRYAN: Well for one thing, once you get solid whatever your discharge i 17l pressure of the makeup pumps is it goes right onto the system. 18j 1$1 HUNTER: Let's say the discharge pressure of the pumps is approximately, 20j it could go as high as I think 2900 pounds. .? l 21i i 22l BRYAN: Yes. I 2 31 24l 25i sna 9. '> iv, a <' l l

24 l i l! l HUNTER: ... if you take the primary system solid and you have the pumps, 2! I would be under the assumption you'd lift the safety valves at 2485 3t i pounds... 4! 5( BRYAN: Right. i 6i 7 HUNTER: ...and you'd be sitting it on safety valves. 8! BRYAN: That's true. t 10t i 11 HUNTER: Have you fellows discussed that? 12 ', 13j BRYAN: That night. 14 i 15 HUNTER: In your training or...? 16l 171 BRYAN: Oh, no. 18i 19! HUNTER: Did you fellows discuss it that night? 20! 21f BRYAN: No. 22l l 23l 24 25, - a, 3 l (/d b

l [ 25 1l HUNTER: You know, Fred Scheimann or anybody with you that morning? 2: 31 BRYAN: Not that I'm aware of. 4! P Gj HUNTER: Okay. You indicated that with a solid pressurizer you might have been inclined to shut down the makeup pumps. Is the reason because the fellows are that sensitive to that solid pressurizer level that they 8 would tend to...to go back to almost no makeup pumps or minimum makeup 9; just to maintain that...try to maintain pressurizer level? 10' 11 BRYAN: Well, really once you get a solid pressurizer you don't r.eed any 12l makeup, at least we didn't at the time, and like you say you're just not 13 set there and operate on the relief valves. 14i 15! HUNTER: Okay. 16l 17! BRYAN: And, the relief valves aren't designed to set there and operate, 18l you know, with a steady flow of water through them like that and once 19l yot get back to a... to get back to a situation that you...you can get 20 another bubble again and you may not be able to get the relief valves to 21] reseat. 22 1 23l HUNTER: Have you seen in Unit 1 or 2 of the case where the relief 2p valves have in fact failed to reseat? Have you ever had that type 25! problem in either of these Units? a r. - y ] LU i

( 26 I, l:' BRYAN: No, but we've never sat there and operated solid. i 2: i 3f HUNTER: Okay. 4! 5! BRYAN: ... with coolant water through them. 6i t 7 HUNTER: You say the main steam safety valves failed to reseat due to 8 failures, other than that one time have you seen any fail to reseat? 9f 10 BRYAN: No. 11 12l HUNTER: Okay. In one of the interviews that we've had they indicated 13 that they had trouble with the A makeup pump failing to start, in one 14! case the makeup pump...the fellow may've held.., failed to hold the 15! switch over for more than a time delay to allow the oil pressure to 16i build up. In another case the makeup pump tripped in like 26 seconds 17l after the heater had been sitting there running for that amount time. I i 18i' 19 BRYAN: Is this that..that night we are talking about? 20i i 21f HUNTER: Yes, and that morning. Are you...I...I...I can understand why i 2 23 if the man doesn't hold the switch for the 3-1/2, it depends on the 23 pump, or 4 seconds for the lube oil pressure to build up. I can under-l 24i stand why the pump would trip back out. I'm having difficulty and so 25i l ( (ll 3

i ( 27 lt j far I haven't been able to determine why the pump would trip after 26 2 seconds and it was just sitting there running. Have you seen this 31 problem with those makeup pumps or with the makeup pumps where maybe the 4 lube oil system fails, or we get a pressure spike, or something, that i i 5 would...the computer didn't printout a low lube oil pressure which it Of would normally do I think if that was the problem so I couldn't key onto 7 that low lube oil pressure. 9 BRYAN: No, I haven't seen that problem. 10t i 11 HUNTER: Alright. The reactor coolant drain tank was a problem the 12 morning when you came over to Unit 2, and you indicated that you had 13{ walked around and looked at the reactor coolant drain tank and I believe 14 that some words about...it may be pumped down or whatever and when you l$l got around it was empty. Would tnat indicate the rupture disc had gone ldi at that time to you? Or do...you know..? 17 18j BRYAN: Not...not right away. 19! 20I HUNTER: Do you know what time it was you walked around and looked at 21 the reactor coolant drain tank? I 22l 23 24j l 25j t ~ on' ~ J bg ( _V UJ t

I 28 l li l BRYAN: No I don't. 2! l 3{ HUNT R: Do you have any feel for the time frame? 4 BRYAN: It was early...within the first hour. 6i i 7 HUNTER: Okay. Had...have you seen the rupture disc blown on the cool-8! ant... reactor coolant drain tank in Unit 1 or Unit 2 before? Or been 9f involved in that type of event? 10f 11) BRYAN: No. no. I 12! 13 HUNTER: Is it..,is it unusual for the reactor coolant drain tank to be 14 hot and high temperature on a reactor trip or a turbine trip when the..after 15: the power operated relief valve opens? 16} 17 BRYAN: That's not unusual, but.c was unusual that it was empty. \\ 181 191 HUNTER: Okay. Did..when you went back around did you tell anybody or 20j did you talk with anybody about that particular item? i 21 22 BRYAN: I think that happened, if I remember the sequence of events 23j right, when I came back around after I had seen that the drain tank was 1 24j empty, it was in a couple of minutes that we got a Reactor Building fire 25[ alarm. l n n '> ~' I i O () t J t

I k { 29 f HUNTER: Okay. i 2! I BRYAN: And that's when we went, I started looking at the temperatures 4' in the Reactor Building and they were increasing. Sj I 6 HUNTER: The temperatures of the containment, Reactor Building tempera-7 tures, were increasing? I 9 BRYAN: Um Um. 10 11l HUNTER: What about the containment humidity, do you have that available 12! to you to look at? 13 14! BRYAN: No. I 15 j 16i HUNTER: Okay. The temperature recorders I believe you indicate... 17 18l BRYAN: Yes. 191 20; HUNTER: ...there are temperature recorders that look at containment 21,! temperatures? Do you recall what the temperatures were? 22 23 BRYAN: Specifically, no. There...I was looking at a trend, you know, 1 24 they were all trending up. 25l ,i on bu\\ tQ l t [

I [ 30 i i 11 l HUNTER: Okay. What would that indicate to you? 2: l f, BRYAN: That we had a leak in the reactor building. 4} 5 HUNTER: Okay. Did you key that to anything? Did we primary coolant 6{ , tak or secondary leak or steam leak in the steam generator or was there 7 some... discussion at that time? 8 9 BRYAN: Yeah, with the drain tank being empty and the temperatures going i 10[ up I think that's when we decided we had blown the rupture disc. i 11! 12! HUNTER: Okay. Did you look at reactor building pressure at that time? 13l t 14! BRYAN: Yes. 15: 16; HUNTER: Do you recall, was it a trend or do you recall any specific 17j pressure numbers? 18i l 19l BRYAN: Around 2 pounds. 20h i 21l HUNTER: Do you recall any discussion about the B steam generator? 22 23 241 25l , o s" 7 g, u gu- 'i I

( 31 1 BRYAN: Yes. P 2; I 3 HUNTER: Giva e.c a fael for that if you would. 4l W;! c BRYAN: l We had the levels increasing in the B much higher than the A and 6f we thought...we thought we had a primary-secondary leak in there and we 7 isolated the B steam generator. 8 9 HUNTER: Okay. That..with the B steam generator isolated and you need 10 to steam to atmosphere or you are steaming to atmosphere, prior maybe to 11{ getting your cire pumps back on, is there a physical valve line up i 12l that's required to prevent steaming the 8 generator or will it just not 13 steam? Do you recall? t 14i 15I BRYAN: Yes, you have to close the...you have to close the feedwater 16! valve...we closed the feedwater valves and the block valves for the dump 17 valves. I don't recall if we had circ water back on. ,I don't think we l 18l did. 19f l 20f HUNTER: If you didn't have circ water, do you close the block valve on I 21t one of the atmospheric dump valves upstairs in the main steam area? 22 23 24f 25! i n it ~1 { <nT c'

i I 32 1; BRYAN: Yes. I 2! l 3I HUNTER: If you had circ water on then would you have closed the block 4 valve on that B side of the condenser? 5 6 BRYAN: It we had circ water on it would have closed itself and we 7 could've reverted back to controlling on the hotwell till the pressure 8 got up so high and then we'd have to close the manual valve at the block 9 valve for the atmospheric relief valve anyway, you'd end up closing up. 10l l 11 HUNTER: What about on the turbine bypass? Is it split also, the turbine i 12I bypass valves? \\ 13! 14l BRYAN: Yes. 15! 16! HUNTER: Would there be a manual valve you would have to close on that 1 also? 18j l 19! BRYAN: There, there, yes. 20t i 21j HUNTER: Okay. 22l 23 SINCLAIR: Let me break here. The time is 3:45 p.m., we are going to 24; take a break here to change this tape. l 25l ,a f (* [, b bbJ k

33 i 1 SINCLAIR: Al right. The time is 3:50 p.m., and we are gonna continue 2 ]' the interview with Mr. B ryan. 31 4 HUNTER: Okay Ken, this is Hunter speaking aga'in. We just discussed 5 isolating the B steam generator and discussed the atmospheric and the 6l turbine bypass valve manual isolation. I'd like to move to the power 7 operated relief valve, the RB2 and the isolation valve on that. In your 8 early stay in the control rocm did you review the condition of the power 9 operated relief valve, the discharge temperatures and what did you see? 10 lli BRYAN: I looked at the indication in the control room. That indicated i 12! it was closed. I printed out the thermocouples on the power operated i 13 relief valve plus the two electric... code safety valves and they all 14' three, the temperatures were all fairly close which indicated I 15i didn't. never thought that the code safety valves opened. So with 16 the temperatures of the three valves being close, I didn't think that 17i the electromatic was open at this time. ) 18 19! HUNTER: Okay. One thing you indicated you didn't feel like the code 2bl safetys... Did you review the pressure chart to see what the pressJres 21l went to during the trip? 22' I 23l BRYAN: 2355, I think we tripped at, and that's when they started going 24 down. 25j i a f\\ l fe1 L,. v (; s : - l 4

l 34 ltj HUNTER: Okay. So you didn't feel like you got to a point where a safety should have lifted? 3{ 4 BRYAN: Right. 5 6 HUNTER: Ah, and the temperatures were reading the same within a few 7l degrees? 8 9 BRYAN: 10, 15, maybe 20. 10l 11l HUNTER: You would suspect if the RB2 valve was open that the temperature I 12! would be much higher than that? l 13l 14 BRYAN: Higher than the other two. 15i 16) HUNTER: The difference between would be higher, okay? So you didn't i 17! suspect a problem at that time? 18j l 19! BRYAN: No, I didn't. 201 21 HUNTER: Okay. An area that ah..you learned later that the power i 22; operated relief valve had in fact been open and they had in fact isolated l' 23l it to the M0V, my understanding is at that time you were in Unit 1 and 241 somebody called you and let ycu know that it was open, right? 25i 0 ,o, m y( l I r

35 l' l BRYAN: Yes, it was Mike Ross. r 2' HUNTER: Okay. So I...that's fine I got to the point. Now, when you 4 called up the power operated relief valve temperatures on the computer i 5 did you call up on the demand log? You said you called this out? 6i 7, BRYAN: Yes. 8 9 HUNTER: Okay. So the numbers that you called up are available and we 10 have been through the particulars. 11' i 12I BRYAN: I turned them out twice probably within twenty minutes, maybe 13 even three times while I was there in the morning. Twice within twenty 14I minutes or so I believe. i 15j 1S{ HUNTER: It's...would you know the time frame that you printed them out? 17 You guys don't initial the log, so I can't tell who prints out what. INj Was it within the first half hour or maybe an hour ah, of the when you 19i came over? t 20: 21l BRYAN: Within an hour. 22 23 HUNTER: Can you key it to an event. Were you doing something when i 24l the..? 25 s ! e,> ~ U' i 1 l l

36 I 1 BRYAN: It was atter I noticed the drain tank was empty. 2t i 3I HUNTER: Okay. So it would be fairly quickly but not within the first j 4l ten minutes or so? i 5' 6 BRYAN: Oh, no. 7 O HUNTER: Okay. Reactor coolant flow was decreasing fairly quickly into 9l the event apparently it started decreasing. Did you review tne reactor 10f coolant flow and watch it as...you know, discuss it with the... Bill 11l Zewe or any of the other people in the control room? 12l 13, BRYAN: Yes, Mike Ross was there by this time I think also. 14l 15 HUNTER: What was your impression of the flow decreasing? 16i l 17 BRYAN: We didn't really know right off...you know. 18i 19) HUNTER: Okay. Now I'm gonna ask you again, I want you to be very 20r honest because I want the information. I want to go back and key that i 21l you had a high pressurizer level, okay? And I want to also go back and 221 say did you review the reactor pressurizer pressure, the reactor coolant 23 system pressure, did you look at it during the time that you were there, 24t like between well, I think you left scmewhere around whatever, 9 or l 25; C:30? I .a ,o' ti-3

j ( 37 l lli l BRYAN: 6:30. 2! l 3 HUNTER: That's right, 6:30. Did you look at the reactor coolant pressure I 4{ during that time? 5 6 BRYAN: Yes, we did and all I could say, at first we didn't know, and we i 7I thought maybe we were getting to a point where the temperature was too l 81 high for the pressure and we were starting to cavitate the pumps. They 9l were forming steam in the pump cavity or something, or net positive 10 suction head wasn't enough at this temperature for the pumps to operate 11{ pre;;erly. i 12l 13 HUNTER: Okay. Do you have curves available to you to use..to look 14! at... to give you an idea about where the pressure should be versus 15, temperature? 16l l 17! BRYAN: We have our heat up and cool down curves. I 18f 19{ HUNTER: Did you look at any of those, or was anybody looking at them 20l that you were aware of? 21l 22 BRYAN: If I remember right we were already outside the curves so we 23 weren't looking at any. 24 25j o' i ,oL v'" { bVI ? l l

f 38 \\ l' j HUNTER: But you were aware, you were aware that you were outside the 2 ' i curve? How did you find out, how did you determine that? Was it automatic i 31 because you know the curve or the temperatures? 4l I Sl BRYAN: With the temperature we were at and the pressure se were at we OI knew we were outside the curve. 7 8 HUNTER: Okay. What does that mean to you being outside that curve? 9 10j BRYAN: In relationship to what, you know, the reactor coolant pumps? I ll! 12l HUNTER: Uh, that's part of it. 13 14!. BRYAN: See the heatup and cooldown curve is based on alot of different i 15! things and it's just...it's one..it's compiled into one curve but each 16l line has different meanings. 17 18l HUNTER: I understand. Do you have in fact like a...I'll look at you 19i and I can talk and I'll draw a picture with my hands but the left hand 20 line of course is the nil-ductility transition limit, okay? And if you i 21! go all the way over to the right hand side of the _urve, there's a i 22f saturation limit curve that's over here. 23 24l 25I n' ) I 7 o (3

i l i ( 39 i \\ r If, BRYAN: Right. 2; 3 H_UNTER: Now there's pin compression limits and pump limits, whatever 4! inside of that but what does that...you're actually outside of your c saturation limit. What does that mean to you? ~ 6 7 BRYAN: Oh, we could be forming steam bubbles. We could be forming 8 steam at that pressure. 9 10 HUNTER: And the reactor coolant pressure at that time was...ah..it 11 varied around by 1200 pounds,1C30, whatever it was 12l 13 BRYAN: Yes. 141 15! HUNTER: Okay. And the pumps were still on, okay? 16! i 17! BRYAN: That's true. i 18l 19{ HUNTER: Flow was down but, and the auxiliary the emergency feedwater 20j system was functioning if you will and you were releasing steam to the i 21j atmosphere. So you were fairly stable from that standpoint, but the key 1 22l issue that keeps coming back to me, okay, is that the pressure was low 23 and if you take ah...if you take the Tavg and walk over to 545 when at 24 that time you were about at 1000 pounds and go up and take your xy plot 25l n

{ 40 1 and... it would put you outside of that... or, you were moving right 2! around the saturation. 3 4 BRYAN: Right. 1 5 Gi HUNTER: Did you discuss that with anybody or did anybody come up and 7 discuss that with you? Do you recall any detailed discussion of it or 8 comments by anybody? 9 l 10' BRYAN: No, I don't recall any detailed discussion of that. It was 11 mentioned and that's all I remember. 12l 13! HUNTER: Okay. The reactor coolant flow decreased and the shift ended 14 up taking off two pumps and they took off the B pumps leaving the A on 15'; and this was my understanding is due to spray. Is there any other 16' reason that you know of that you would pick the 8 rather than the A? i 17, 18j BRYAN: No. You need the spray. No, I don't know any other reason. 19! 20i HUNTER: Okay. I don't either, I just want to make sure that I'm finding i 2h the key to going to get all the information I can. Ah, were you a 22l there when they secured the last two pumos? I 23! I 24 L Y 25i o I i

c ( 41 i I 11 BRYAN: What time was that? 2: l 3! HUNTER: Ah, well the first two went off 74 minutes into the event which 4! would be slightly, you know, would be past 5 and then the next one went i 5! off at 100 minutes which was right before 6. I 6l 7 BRYAN: Yes, I was there. l 9 HUNTER: Okay. One of the discussions that apparently went on or it 10 appears to have gone on was going on natural circulation when you take 11l these reactor coolant pumps off. Give me a feel about natural circula-t lIl tion and what you...what, your uncarstanding of natural circulation, and 1 13l what's required to go on natural circulation. Besides the fact that you IN turned the pumps off when you were there,.Jt look .. go through a 15; little bit of your understanding. I'm not the... I'm a B&W expert now, 16 I guess, but give me your feel for the natural circulation requirements 171 and talk procedure if you want to, I don' t mind you talking about a I 18! procedure at all, and talk. whether or not you had a procedure in 191 your hand or whether or not you saw somebody with a procedure. 20f 21l BRYAN: I don't recall seeing anybody with the procedure at this time. 2 21 I'm not saying they weren't. I 23[ l 241 1 i i t

i i [ 42 i P 1;' HUNTER: No, I understand. 2: l 3 BRYAN: But ah, because by this time... 4! i St HUNTER: You didn't have ane. I 61 i 7 BRYAN: No, I didn't have one. There were quite a few other people ip 8l the control room by this time and I know the problem was to turn the 9l reactor coolant pumps off and to go on natural circulation but I know if 10 the steam bubble was in the top of the steam generator, which we didn't 11l know at the time, you can' t get natural circulation very well if you 12l can't get flow around the whole loop and I guess that's what we had at i 13! this time and natural circulation doesn't work as well without it. 14! t 15t HUNTER: Is there any requirement to raise steam generator levels prior 16 to going on natural circulation? 17' 18: BRYAN: Oh yes, you have to be at 50 percent. Well, I don't know if it 19! is required betore you secure the pumps. The emergency procedure is if 20 the.. all flow reactor coolant pumps trip the steam generators go on 21l level control at 50 percent, through the emergency feedwater valves. I 22 23 i 24l 25l a / Ol Lt U UV J f D

l [ 43 l i 1}! HUNTER: Ana that's 50 percent on the...which range? 2: I 3 BRYAN: 50% on the operating rango. 4, Si HUNTFR-50% on the operating range. What would that give you on the j 6l startup? I 7 8 BRYAN: 95%. i 9 10l HUNTER: 95%? Good enough. 1 11 l 12! BRYAN: The emergency procedure is probably written for operating at i 13 some percent power when the steam generators are already higher in that 14! level or around that level. f 15j 16 HUNTER: Okay. 17l 18; BRYAN: So if you would lose all four reactor coolant pumps you already 19! have your..the level established in the steam generators. 20t i 21l HUNTER: Let me go back when..were you there when they secured the 22 first two pumps? 23l 24! 25! ,., q o u)- in L l I

44 r l{' BRYAN: Yes. 2; 31 i HUNTER: My understanding now is that they were trying to protect the 4! pumps and if I'm wrong tell me. 5l i BRYAN: That's true. 7 8 HUNTER: The pumps were vibrating and they were making noise. They were 9 vibrating, the rpms were varying, they were getting... the computer was 10! printing out alarms on another backstop all pressure, etc., etc., so you 11; guys had indication that the pumps were in fact under stress. 121 f 13l BRYAN: Right. 14 15;' HUNTER: And so the first two pumps you secured, the B pumps, was anybody 16! or do you recall watching the B loops the steam generator what the 17! actual loops did at that time? Was anybody watching that particular 18r parameter? 191 20: BRYAN: No. Not that I know of. 21 i 22l HUNTER: I can indicate to you by the charts and the graphs and review 23 the event that when those two pumps were secured no backflow occurred. i 24l Not one smidgen occurred. Now if you secured two pumps and you still 25! .c }, I [Jo ) i i

l [ 45 I l t l' j have two running and there is no backflow, what would that indicate to 2 you? 3 t, 4l BRYAN: You say I have tio backflow through the tube operating under its i coolant pumps? 61 HUNTER: Through the two secured reactor coolant pumps, the two that are 8 down. No backflow at all through the B generator when they took that 9l off...when they took the B pumps off...they just died. That locp just i 10l died. I 11! i 12l BRYAN: That would indicate that it's got a steam bubble on top the loop i 13! and you know tha water can't flow the whole way through. t 14i 15' HUNTER: Okay. I want to make sure. I'm not used to the J-leg type 16l generators but louking at the...you take off two pumps in a solid system t 17! you would expect backflow and that generator would in fact steam some 18! and it would come to equilibrium and you would be sitting. You indicated 19l that you picked up procedures wnen you came to Unit 2. Do you recali 2 which procedures, emergency procedures that you reviewed? 21j 22l BRYAN: Turbine trip and reactor trip. I 23l 24l r

2bi, u-

\\ t i

I f 46 l{! HUNTER: Were there any others that you reviewed? 2' l BRYAN: No. 4l i 5l HUNTER: Okay. Part of the turbine... reactor trip procedures, I think O! in both of them requires a sample to be taken on the reactor coolant 7 system after the trip. Did you, wer. Ju involved in that particular 8 request? 9 10 BRYAN: Yes, more or less. It might have been done by someone else also ll! but I happened to see Dick Dubiel, he's the Chemistry Supervisor, he's i 12 the HP and Chemistry Supervisor, and I said you know you got a requirement 1Nl here for a greater than 15 percent power change, you have to take a 14! sample, and he says yes. Whether someone else had told him that before 15: or I was the first one I don' t know. 16: 17 HUNiER: Did you get the results back on the samples while you were 18i there? 19! 20I BRYAN: No. I was sitting in Unit 1 when they took the samples. That's 21) when we found out that we had some problems. 22lI 23! l 24l 25! 's i

l 47 6 HUNTER: Okay. 2! k BRYAN: Cause the sample lines run into Un't 1, they come by the hot machine shop and into the sample room and when they put the thing on

• l*

recirc we got the high radiation alarms in the hot machine shop and the 6 sample room. 7{ 8 HUNTER: Okay. What about the boron concentrations? Were you there 9 when an earlier sample was taken? I'll go a little further. The situ-10 ation that you are talking about occurred after the pumps were off, 11l okay, but apparently somebody requested that the chemistry lab place i 12 the... obtain a baron sample for the shutdown margin check and the 13 cale.ilation for restart, whatever the requirements are, and they put it 14 on recirc early. There was no radiation problem at that time. 15i 16! BRYAN: Early, what do you mean? 17f 18( HUNTER: That was at 4:45 or so and you got the sample about 5:00 and 19l then they called it into the control room and it was 700 parts per 20j million. Do you..were you aware of that particular number? l 21! i 22 BRYAN: No. That's the first I heard that. 23, l 24! ?Si () c..(,) A .w I

j i i ( 48 l 1: HUNTER: Ukay. Well then the second sample was in fact later on, and 2' i another sample, and Dick Dubiel had two people split the sample. Were 3l you aware of the results of that sample? That was after you left. i 4! cl] BRYAN: No. 6i 7l j HUNTER: Okay. When you were in the control room did you look at the 8 source range instrumentation, the intermediate range instrumentation? 91 10' BRYAN: No, I didn't. 11l 12l HUNTER: Were you aware of any emergency borating that was going on? 13i 14! _B RYAN: No. i 15' E 16! HUNTER: Okay. You were not involved in any discut by the...taking 17! off the second set of pumps. Were you involved in a d-assion as far I 181 as natural circulation and the requirements? Do you recall discussing 19l that? Kunder was there, okay, Mike Ross, Bill Zewe. 20 21l BRYAN: Brian Miller. I 22 23 24l 25j 1 [ () / 'l ' ' i l OOJ L<

49 i - l N HUNTER: Brian Miller was there? i 2; i 3l BRYAN: Yeah. Right after Brian came in was when I went back to Unit 1. 4! Si HUNTER: Okay, I understand that. Si 7 BRYAN: And, no I wasn't involved in that conversation. 8 ! Sl HUNTER: Okay. There was some discussion about ah, well let me go back i 10 again I'm just trying to fill in some blanks, the auxiliary feedwater..I 11l mean the auxiliary steam system is used for Unit 1 for feedwater heating 12l I gather during the normal heatup. Unit 2 needed the auxiliary feedwater 13 for ah...to maintain a vacuum after they had tripped. Ah, and ah so 14! when Unit 2 came down you needed to from Unit 1 to supply them steam for r 15: the vacuum. Did you guys get in a discussion at that time about supplying 16! auxiliary steam? 17; IS! BRYAN: Yes. 19l 20l HUNTER: Was it a, did you end up supplying steam to Unit 2? 21, 22 BRYAN: Uh, huh. 23t i 24! 25\\ m,- 5 {_ l.-- r C.t. i e

50 l i' l HUNTER: How did you, how did you end up, I have got the impression from ]4 some interviews and all that Unit 1...that there was some hesitancy at 3r first to supply steam and I guess that's the best way to rightly put it. Did somebody, were you over in Unit... 5 b BRYAN: You can't ren both Units with one aux boiler and Unit I was 7 sitting at the poirt where we were about ready to go back on the line. i 8l 9 HUNTER: Okay. 10 11 BRYAN: And we were already heated up. The Unit 2 was down and we knew 12{ it was going to be down for awhile. I'm speaking of a day or two at i 13! least you know at this time, and the decision I guess was made, earlier 14 we will get Unit 1 on and we'll worry about Unit 2 later, but, as it 15l turned out during the course of the day and that we had to get turbine 16 seals on the Unit 2 for the cooldown, we...you know..we just took Unit 17 1 back to nothing and gave Unit 2 the steam. 18j 19! HUNTER: Okay. Then do you recall...was the decision to supply Unit 2 20 steam while you were in Unit 2 or had you gone back to Unit l? i 21L 22j BRYAN: I left Unit 2 early. The decision was Unit 1 gets the steara. 23 24, o(u) 5 U / i i

51 HUNTER: Okay. 2: 1 3 BRYAN: And there was a couple of control room operators called and said I 4 I they want steam and I kind of ignored that and I forget somebody else 5 called up a couple of times and Mike or Bill or somebody called later on OI and said we decided we are going to put the seals back on the turbine in 7 Unit 2 and this and that. So we started cutting back on the feedwater 8j heating in Unit I and we ended up cutting it back almost to nothing. 9 10j HUNTER: And then... Unit 2...then you were able to maintain better seals 11! and get the vacuum? In order to not dump steam to the outside that's 12 my understanding that they have to have one of these 13 i 14 BRYAN: You have to have a vacuum. 15, 16 HUNTER: Gland seal steam system on a vacuum, okay. I have in fact 17! covered all the areas that I need to cover, do you have any questions or 18i is there anything that you would that you need...oh I have one more 19! question. This is sort of off the cuff. Jim Floyd was in Lynchburg. 20! i 21i BRYAN: Uh, huh. t 22! 23 24 i ,q7 25 in1 e.! UU 3 ^ i e

BRYAN: I don't remember the specific questions, but they had heard 13 about it down there and ha had called and he wanted to know some temper-14 atures, radiation monitor readings, and I gave him those numbers over 15: the telephone. He was down there with Bernie Smith and I guess some of 16I the head people from B&W were all sitting around talking about it. 17! i 18! HUNTER: Okay. I just wantea tc make sure that that was the type conver-19i sation you had. He wanted some numbers and you gave him the numbers. 20! Did you have to take any messages to Unit 2 or did you have to go to 21 Unit 2 to get any messages or it was it just a general conversation? 22f 23l BRYAN: It was a general conversation at first and I gave him the numbers i 24j off the top of my head that I had seen when I left there. 25! r, q, ),' 1
