Title: Nuclear Regulatory Commission’s Fukushima Transcripts
Date: March 17, 2011
CASTO: [...] Now, what they’re doing is they have bulldozers — I mean, the dose sounds like not as much a shine from the building as when the building blew up. There is spent fuel and pellets and whatever all over the place around the plant. So they are taking the bulldozers through and pushing the rubble in piles, and they are saying that’s cutting the dose down, you know, 60, 70 percent.
So they are trying to — in these areas where the piping runs would go, they are trying to clean it up. But, I mean, the dose is still going to be, you know, incredible. I mean, they were talking yesterday, they said the resources they have were somewhere between 2- to 300 people, and that, you know, TEPCO and other licensees, the Civil Defense Force and some — some police.
MALE PARTICIPANT: I don’t know. They asked us how we deal with extending dose, and we just told them for emergencies and a condition like this, we have guidelines that let us go to a certain limit. But in this case, you need to do what you need to do to get it done.
MALE PARTICIPANT: We saw some media reports yesterday that said that they were — they had authorized going to 25 rem.
MALE PARTICIPANT: Yeah. Obviously, they need more — they need more people to spread that around, so that people aren’t getting in excess of 25 rem.
MR. CASTO: And they — you know, not just for the pool cooling, but they talked about our personnel to, you know, be embedded with their personnel. And they said no. I mean –
MALE PARTICIPANT: Thank you, John.
MR. CASTO: — you know, we’re not going to do that.
MR. VIRGILIO: Yeah, right, right. I mean, but that’s — then, they need to get out and recruit more than the 2- to 300 people they have.
[...]MR. CASTO: It got the MOD’s attention and they called us in and we had the big meetings, but — but, you know, nevertheless, I mean, they’ve still got, you know, people to worry about, and they have a huge crisis up there in terms of, you know, all the things from, you know, hazardous material, deaths, all that that they’re trying to deal with with their military. you know, so do you — you know, so it’s a terrible situation, and you evacuate, you keep people safe, and then we address this problem methodically, you know, without — because it is probably already at its worst-case scenario, and maybe stable. You know, if there are rubble beds in there in the spent fuel pool, right now there is — it doesn’t seem to be getting worse. So it’s — you know, it’s stable with regard to — whatever the rubble bed is, we’re not getting zirconium fires that we can tell or, you know, anything — it’s always –
MALE PARTICIPANT: Right.
MR. CASTO: It’s stable where it’s at, so, you know, you get the people away, and then, now, okay, let’s methodically, you know, without just running the military in there to kill people, just to, you know, make us feel like we’re solving the problem, you know, so we’re — you’ve got to kind of take it slowly. You know, let’s get the people out of the way. Now, let’s, you know, methodically go through this and, you know, without a lot of loss of life.
JOHN: [...] they gave us the dose rates of, what, 20 to 30 rem per hour [...] they said, you know, the dose rates go down 70 percent when they bulldoze [...]
