7 10! MR. PARTICIPANT: And the ET Bridge.
11 MR. LANNING: Mr. Ryan, are you there?
12 MR. RYAN: Yes, this is the manager of 13 Communications.
14 MR. LANNING: Is this Mr. Ryan?
15 MR. RYAN: This is Mr. John Ryan.
16 MR. LANNING: Mr. Ryan, it's Wayne 17 Lanning. I'm looking for a couple of things, if you 18 could. First, could you give us an update of the 19 status of the plant and planned actions? And then I'd 20 like a discussion pertaining to what notifications you 21 have been making to the local officials and what press 22 releases you have issued.
23 MR. PARTICIPANT: We called the managers, 24 right? We don't call the duty officer to --
25 MR. PARTICIPANT: Someone has their mike NEAL R. GROSS COURT REPORTERS AND TRANSCRIBESk9 1323 RHODE ISLAND AVE., N.W. ERS 433 (202) 234-4433 WASHINGTON, D.C. 20005-3701 ( 02)
22 1 open.
2 MR. PARTICIPANT: Right. But we also call 3 the managers, right.
4 MR. RYAN: Hello? This is the Manager of 5 Communications John Ryan. Ready for a plant brief.
6 MR. PARTICIPANT: John, can you stand by 7 a minute?
8 MR. PARTICIPANT: (Inaudible.)
9 MR. PARTICIPANT: John Ryan?
10 MR. RYAN: This is John Ryan.
11 MR. PARTICIPANT: Go ahead, John, with 12 your brief.
13 MR. RYAN: I understand to go ahead with 14 the brief. The plant at this present time is just 15 cooled by 88 degrees. RCS pressure is 2260. The 16 maximum thermocouples are 565 degrees. Reactor vessel 17 level is 100 percent. The RCS -- sorry, the 18 pressurizer level is 57 percent.
19 At the present time, we are cooling down 20 the PRT pressure relief tank using primary grade 21 water. And that's why you are seeing, if you're 22 watching the ERDS system, you're seeing PRT level and 23 pressure increasing. And on decreasing, we did pump 24 it down.
25 On the secondary side, as far as the NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
(202) 234-4433 WASHINGTON, D.C. 20005-3701 (202) 234-4433
23 1 secondary side goes, the steam generator pressure is 2 coming up right now -- are approximately 1,080 pounds 3 on all four steam generators. We are feeding the 4 steam generators on aux feed, maintaining steam 5 generator level.
6 And radiation levels have not changed 7 since the initial event. And they did not change 8 during the initial event.
9 MR. LANNING: John, would you clarify what 10 you mean by that? Is this based on a secondary sample 11 or what?
12 MR. RYAN: No, this is based on the 13 radiation monitoring system in the control room, RAD 14 monitors.
15 MR. PARTICIPANT: (Inaudible.)
16 MR. PARTICIPANT: Have you confirmed you 17 have no primary or secondary leaks?
18 MR. RYAN: At the present time, we have 19 sampled alpha, bravo, and charlie steam generators and 20 there is no RAD levels detected in there. And we have 21 determined that there is no primary or secondary leak.
22 We are getting a sample on the delta at this time.
23 MR. PARTICIPANT: Did he mention D?
24 MR. PARTICIPANT: Yes, A, B, and C.
25 MR. PARTICIPANT: Okay. D is in progress, NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
(202) 234-4433 WASHINGTON, D.C. 20005.3701 (202) 234.4433
24 1 is that correct, John?
2 MR. RYAN: Delta is in progress, that's 3 correct.
4 MR. PARTICIPANT: All right. Go ahead.
5 What can you tell us about the indication of leaking 6 through the PORV or the primary safety value?
7 MR. RYAN: At the present time, the PRT, 8 which is the pressure relief tank, is -- the level is 9 fluctuating because we're pumping it up and cooling it 10 down with primary grade water so the detection on that 11 is really not available to me. I can get you tailpipe 12 temperatures on the relief valves. And I'll get them 13 while we continue to talk.
14 MR. PARTICIPANT: Okay. I'd appreciate 15 that. I understand -- are you still doing normal 16 charging and let downs?
17 MR. RYAN: Yes, we are still doing normal 18 charging.and let downs. We are still in ES 1.1, which 19 is determination criteria. And we are doing a brief 20 right now to enter OP3208 which is RCS boot up.
21 MR. PARTICIPANT: John, are you still in 22 the alert classification?
23 MR. RYAN: Yes, we have not changed our 24 classification level.
25 MR. PARTICIPANT: Are you -- can you give NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
.(202). 234-4433 WASHINGTON, D.C. 20005-3701 (202) 234-4433
25 1 us some insight as to what parameters must be met to 2 exit the alert and maybe go to a UE or whatever?
3 MR. RYAN: The directors are discussing 4 that at this time. And that's why I'm giving you the 5 brief. They're in a meeting right now. But as soon 6 as we know, I will get back to you.
7 MR. PARTICIPANT: Okay. All right. I'm 8 going to stand by for the tailpipe temperatures.
9 MR. RYAN: That's correct. And while 10 we're standing by for them, we have released three 11 incident report forms which go out to the local 12 officials and the state officials. And all of the 13 first selectmen within the emergency planning zone get 14 a page and they can call in and get a recording as to 15 what the incident report form's content is. Those 16 were faxed to Region I.
17 MR. PARTICIPANT: We have not received 18 those, John.
19 MR. RYAN: I faxed them to the Region I 20 office.
21 MR. PARTICIPANT: We have not received 22 those.
23 MR. RYAN: I understand you have not 24 received them.
25 MR. PARTICIPANT: We'll give you another NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.

27 1 MR. PARTICIPANT: That's correct.
2 MR. RYAN: Understand; 3 MR. PARTICIPANT: And they should ask for 4 the Reactor Safety -- no, the ENS Bridge.
6 MR. PARTICIPANT: ENS, Emergency 7 Notification System Bridge.
8 MR. RYAN: ENS Bridge, right. Understand.
9 And who would you like to speak to?
10 MR. PARTICIPANT: The communicator.
11 MR. RYAN: The Technical Support Center 12 does not have a communicator. All the communications 13 come out from the EOF here. They come through me.
14 MR. PARTICIPANT: Stand by a minute.
15 MR. RYAN: I understand.
16 MR. PARTICIPANT: (Inaudible.)
17 MR. PARTICIPANT: Mike Weber is on the 18 Bridge.
19 MR. DYER: Mike, this is Jim Dyer. This 20 is an ongoing alert. We're just getting a briefing 21 now. I can take you on a different line.
22 MR. WEBER: Okay, whatever works for you, 23 Jim. You're there in the Op Center, I understand.
24 MR. DYER: Correct.
25 MR. WEBER: Okay.

28 1 MR. LANNING: John Ryan, it's Wayne 2 Lanning again. Cancel that request for a communicator 3 from the TSC.
4 MR. RYAN: I understand you want me to 5 cancel the TSC communicator request.
6 MR. LANNING: That's right.
7 MR. PARTICIPANT: (Inaudible.)
8 MR. LANNING: We're still in a standby for 9 the tailpipe temperatures.
10 MR. RYAN: Yes, the tailpipe temperatures 11 right now are 220 degrees and stable.
12 MR. LANNING: And what is your 13 interpretation of that with regard to leakage?
14 MR. RYAN: I'd have to get back to you on 15 that as to whether the TSC has determined whether 16 there is any significant leakage.
17 MR. PARTICIPANT: John, have they been 18 able to discriminate where the leakage would be from 19 by acoustic monitors or from the tailpipe 20 temperatures?
21 MR. RYAN: I haven't been able to 22 establish that right now. But we can look at that out 23 here at EOF. What I'm going to do is I'll get the TSC 24 to answer that question for us, the Technical Support 25 Center.

29 1 MR. PARTICIPANT: Okay. We're also 2 interested in seeing if there is any thoughts of 3 closing the block valve.
4 MR. RYAN: Well, the pressurizer safety 5 valves do not have block valves.
6 MR. PARTICIPANT: Oh, you've established 7 then it's leaking from the safety not from the PORV?
8 MR. RYAN: We believe that it is leaking 9 from the safety because we did have one safety that 10 did open.
11 MR. PARTICIPANT: Had it opened before the 12 PORVs opened?
13 MR. RYAN: Yes, it did.
14 MR. PARTICIPANT: Okay.
15 MR. RYAN: At the present time, PORV --
16 block valve status is intermittent. I have a partial 17 closure on it.
18 MR. PARTICIPANT: John, would you say that 19 again about the block valve on the PORV?
20 MR. RYAN: The block valves right now on 21 the indication are reading partial. I just have a 22 closed/partial status. And right now both are reading 23 partial.
24 MR. PARTICIPANT: Is that two valves?
25 MR. RYAN: That is two valves. RCS No.

30 1 Z8000 alpha and bravo.
2 MR. PARTICIPANT: We need to know what 3 that (inaudible).
4 MR. RYAN: At the present time, we're 5 getting information on whether or not the control room 6 has more information on that partial status there.
7 MR. PARTICIPANT: Okay. Thank you, John.
8 We're also standing by for when you get the results 9 from the steam generator secondary side.
10 MR. RYAN: Delta, delta steam generator.
11 MR. PARTICIPANT: Delta, that's correct.
12 MR. RYAN: So I have a delta steam 13 generator sample that I will get back to you on as 14 well as an update on what the block valve status means 15 by saying a partial.
16 MR. PARTICIPANT: And also an evaluation 17 of the tailpipe temperatures.
18 MR. RYAN: And an evaluation of the 19 tailpipe temperatures, that's correct.
20 MR. PARTICIPANT: Now I understand that 21 you are in the process of removing the contents from 22 the PRT, is that correct?
23 MR. RYAN: Yes, what we are doing is we're 24 pumping down the PRT and then filling it with primary 25 grade water to get the temperature down and get it NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.
(202) 234-4433 WASHINGTON, D.C. 20005-3701 (202) 234-4433
31 1 within its normal band.
2 MR. PARTICIPANT: Okay. Could you also 3 confirm you still have no sump level indication as far 4 as leakage?
5 MR. RYAN: Yes, just a second. I can 6 confirm that.
7 MR. PARTICIPANT: (Inaudible.)
8 MR. RYAN: Wayne, this is John Ryan.
9 MR. LANNING: Go ahead, John. Wayne here.
10 MR. RYAN: PORV block value, pressurizer 11 PORV block values are open.
12 MR. LANNING: Help me understand that. So 13 if you think one of those are leaking --
14 MR. RYAN: We don't believe the PORVs are 15 leaking. We believe the leakage is actually coming 16 from a safety valve. And that safety valve does not 17 have a block valve on it.
18 MR. LANNING: Okay. Help me understand 19 that, John. Is that because of -- what kind of 20 indication that gives you confidence that the PORVs 21 are not leaking?
22 MR. RYAN: That's what we're doing the 23 tailpipe evaluation on right now.
24 MR. LANNING: Okay. So that is to be 25 determined?

2 That's correct.
3 MR. LANNING: Okay. John, can you give us 4 an update on any initiating -- what caused the event?
5 MR. RYAN: We still do not have what 6 caused the event. That's to be determined.
7 MR. LANNING: Okay. Thank you.
8 MR. PARTICIPANT: (Inaudible.)
9 MR. PARTICIPANT: Millstone Station on the 10 line.
11 MR. LANNING: Is this the Emergency 12 Director? This is Wayne Lanning in the IRC.
13 MR. HOFFNER (phonetic): This is Bill 14 Hoffner. I'm the Director of Station Emergency 15 Operations. I also have Dave Dodson (phonetic) and 16 Steve Scason (phonetic) here with me.
17 MR. LANNING: Okay, Bill. We just got a 18 brief by John Ryan regarding plant conditions. I'd be 19 interested in a couple of strategies on your part.
20 The first -- what is your plan going forward?
21 MR. HOFFNER: Our plan is to complete the 22 emergency EOPS 1.1, which is safety injection 23 termination. Then we will transition to normal plant 24 operating procedures which will have us initiate plant 25 cool down. We will initiate plant cool down to cold NEAL R.

(202) 234-4433 WASHINGTON, D.C. 20005-3701 (202) 234.4433
33 1 shut down.
2 MR. LANNING: Okay. (Inaudible). Can you 3 tell me -- I understand that you are still in the 4 alert status?
5 MR. HOFFNER: That is correct, Wayne.
6 MR. LANNING: Can you share with me what 7 some of the parameters are that would permit you to 8 exit that EAL?
9 MR. HOFFNER: Where we're looking right 10 now is to get the plant starting to cool down. We are 11 looking at containment pressure right now. Because we 12 lost cooling water to containment, the pressure is 13 just slightly above tech spec pressure.
14 So once we begin the cool down and we get 15 containment pressure back in specs, we're already 16 reviewing our termination checklist right now. So we 17 would expect later this afternoon to be able to 18 terminate.
19 MR. LANNING: Can you expand upon the 20 reasons for the loss of containment cooling? That's 21 new information to us.
22 MR. HOFFNER: It's actually a chill water 23 system. And that's a non-safety system at post 24 accident it isolates the chiller portion. And so 25 we've reset that and we've reinitiated it.

(202) 234-4433 WASHINGTON, D.C. 20005-3701 (202) 234-4433
34 1 MR. LANNING: Thank you for that. I 2 understand you reinitiated chill water containment 3 cooling.
4 MR. PARTICIPANT: (Inaudible.)
5 MR. LANNING: Bill, could you confirm for 6 us conditions inside containment in terms of the site 7 temperature and humidity for example?
8 MR. HOFFNER: I would have to get that 9 data, Wayne. We've had no reports of any indication 10 that other than from the loss of coolant, any 11 indication of any leakage or anything like that if 12 that's what the questions are heading towards.
13 MR. LANNING: That's really the question.
14 MR. HOFFNER: The loss of coolant has 15 caused the pressure to go up.
16 MR. LANNING: Yes, that's the question.
17 MR. PARTICIPANT: (Inaudible.)
18 MR. HOFFNER: Right. We do have a small 19 amount of leakage going to either one of the PORVs or 20 safety that's going into the PRT, primary relief tank.
21 We have been pumping that down so the pressure in the 22 primary relief tank, PRT, is intact.
23 MR. LANNING: Bill, I understand that your 24 two block valves for the PORVs are still open. Is 25 that correct?

(202) 234-4433 WASHINGTON, D.C. 20005-3701 (202) 234-4433
35 1 MR. HOFFNER: Let me take this phone call.
2 They are still open. We were going to go and cycle 3 them to see if that could stop the leakage. What we 4 have is we have three safeties and two PORVs and they 5 all come into a common line. So we want to see if the 6 leakage into the PRT we can isolate by shutting one of 7 the two block valves. So we're going to be working 8 through that very shortly.
9 MR. LANNING: Okay. Bill, I understand 10 you had a packing leak in the auxiliary building from 11 the charging system. Is that correct? And does that 12 constitute a release?
13 MR. HOFFNER: We did have a confirmed 14 leak, a packing leak off a charging line. The 15 charging line that leak is not a normal flow path 16 line. Following the safety injection, a release of 17 the charging pumps get a line back to RNSE (phonetic).
18 The valve leaked was on this line and the 19 line has been isolated. We have no airborne 20 indications at all. No change in our RAD monitors, 21 effluence. We do have some small amount of surface 22 contamination that we're in the process of cleaning 23 up.
24 MR. PARTICIPANT: (Inaudible.)

36 1- specifically around one of our charging pumps where 2 the valves are located.
3 Wayne, did you receive that?
4 MR. LANNING: That's affirmative. I did 5 receive that. I also understand that you have no 6 airborne alarms or elevated level?
7 MR. HOFFNER: Yes, we've seen no trends in 8 any of our RAD monitors that would indicate any 9 airborne effluent releases.
10 MR. LANNING: Okay. I understand you have 11 no indication or trends in RAD releases.
12 Okay. Stand by a minute. All right.
13 Bill, thank you for your brief. Is there anything 14 else you want to add?
