WEDNESDAY – MARCH 16, 2011

 

CHUCK CASTO: I reviewed the video. Tony and Brook (phonetic) and I reviewed the video. You know, it’s not very clear. You’re talking about a helicopter that’s trying to do a lot of things at once in a field. And they tried to scan all four units. You have to look through a window. And they claim there’s a reflection of water on the Unit 4 spent-fuel pool.

It’s not clear. I mean you really can’t see anything. There’s something there. You don’t know if it’s steel or water. They claim it’s a reflection.

 

CHUCK CASTO: The Chairman, you know, we need to probably let Bill and the Chairman know that on yesterday we were going by we thought that, with the explosion, there was structural damage to the Unit 4 spent-fuel pool. We don’t really know if there’s any integrity in that pool or not. The video doesn’t really show if there’s integrity.

There’s some what they claim is reflection, but we can’t tell. We knew there is some water in there as of five o’clock yesterday because it’s steaming.

So, I think the right call is still on Unit 4. And Unit 3 is steaming even worse.

 

MALE PARTICIPANT: You don’t have a copy of that video, do you?

CHUCK CASTO: They claim that it’s a special video file that takes a special video player and all this stuff, software, and the file’s too large to give to us. Imagine that.

MALE PARTICIPANT: Yes.

CHUCK CASTO: Look, they’re not going to let us have that video. You know, the next thing you know, that thing gets out. You know, they’re not interested in sharing that thing with us right now.

MALE PARTICIPANT: No, no, I was just asking to complete.

CHUCK CASTO: Yes. I mean that was a good question. We asked that, and it was asked in the meeting, and they said no.

 

BILL: Do we know it’s the Unit 4 spent- fuel pool? Are we certain that that’s the case?

CHUCK CASTO: Well, that’s a good question, Bill. Because the guy that was showing us the video from Conti, from the Government, said,

“TEPCO told us this is where the spent-fuel pool is.”

So, we don’t even know that that’s the damned spent- fuel pool that we was looking at.

NRC CHAIRMAN JACZKO: Chuck, Chuck –

CHUCK CASTO: All we can tell is some feet away, some feet away, there was steam coming out of the building. And they said, “Well, yeah, that’s not right where we think the spent-fuel pool is, but the wind’s blowing really hard today and the wind’s blowing the steam away from the spent-fuel pool.”

 

NRC CHAIRMAN JACZKO: Chuck?

CHUCK CASTO: So, we really don’t know what the hell we looked at.

 

CHUCK CASTO: I’m sorry. TEPCO and Conti, the Japanese Government showed us snapshots, and it looked, after the explosion, and it looked like the pool had lost structural integrity of the snapshots. Those were outer walls of the building. Today they’re saying, well, the pool doesn’t have an outer wall, is not associated with the outer wall, so they could still be intact.

However, they flew a helicopter by the four units, and it’s really inconclusive as you look at the video, which they showed us, but won’t share it with us, for whatever reasons. And they say, “Look, there it looks like a reflection in there.” And we said, “Well, is that the spent-fuel pool?” And the guy says, “Where that’s where they tell us the spent- fuel pool is, and we think that’s a water reflection.”

 

NRC CHAIRMAN JACZKO: Okay. But we’re not necessarily good with the statement that the pool is dry?

MARTY VIRGILIO: Well, that’s not, you know, our four points don’t speak to the pool being dry.

NRC CHAIRMAN JACZKO: Right, right. No, I know, but they speak to my credibility. That’s the problem.

MARTY VIRGILIO: Yes, but think about where that statement came from. It came from TEPCO to John Monager yesterday.

NRC CHAIRMAN JACZKO: Okay, that’s the source of it?

MARTY VIRGILIO: Yes.

NRC CHAIRMAN JACZKO: TEPCO said the pool was dry?

MARTY VIRGILIO: That’s what he told John Monager yesterday, and they asked John, given a dry pool, what are the four or five things, what things could we do to control the radiation release?

NRC CHAIRMAN JACZKO: Okay.

CHUCK CASTO: And I don’t think that’s the only one. I think, to Jim Trapp, they told him the same thing.

NRC CHAIRMAN JACZKO: Okay.

CHUCK CASTO: Now today they’re saying, “Well, we were just postulating that it would go dry.”

NRC CHAIRMAN JACZKO: Okay.

MARTY VIRGILIO: I mean that was pretty clear with Monager; they had told him it was dry and we needed some actions. What actions would you take if you had lost the integrity of the pool?

NRC CHAIRMAN JACZKO: Okay. That’s fine. Okay.

MARTY VIRGILIO: So, TEPCO and the Government are now changing their position. That’s great.

NRC CHAIRMAN JACZKO: Yes.

MARTY VIRGILIO: You know, I am hopeful, I’d like to see a better situation than we had yesterday.

NRC CHAIRMAN JACZKO: Yes, yes. Okay.

MALE PARTICIPANT: Notwithstanding we’re also recording dose rates in rems per hour in the vicinity. So, at a minimum, there’s at least a significant amount of fuel that’s exposed.

NRC CHAIRMAN JACZKO: Yes.

MARTY VIRGILIO: Right. The last I saw was 30 rem between Building 3 and 4. I don’t know where that number came from.

MALE PARTICIPANT: That’s right. That’s from uncovered fuel.

MARTY VIRGILIO: Right.

 

NRC CHAIRMAN JACZKO: Okay. Okay. Does that uncertainty change any of our views about the recommendations?

MARTY VIRGILIO: No, not the 50 miles.

NRC CHAIRMAN JACZKO: Okay. But the fourth, the Point No. 4? Marty, you know what the No. 4 point is?

MARTY VIRGILIO: Yes. Yes, I’m looking at it, and, yes, I would say yes, based on — and again, this is based not necessarily on radioactive dose alone.

NRC CHAIRMAN JACZKO: Okay. So, you’re saying you’re still comfortable with No. 4?

MARTY VIRGILIO: Yes.
