DN Y Craig Faust - April 21 NRC I&E Interview b

1 FAUST:

Something else I would like to just emphasize is that just prior to stopping those pumps, we did reinitiate, we hit high pressure injection just prior to stopping the pumps.

I don't know if that was brought up before, it 1

should be though.

We got the decision, in other words, we made the decision and I'm not sure how you can look at that.

HUNTER:

Okay.

And one point you pointed out and I under-stand.

. and we'll still talk about, I want to go back before you stopped the pump.

You indicated that you had manually initiated ESF safety injection, and at that time j

that would put the two high pressure injection pumps on?

FAUST:

Right.

HUNTER:

At maximum flow?

FAUST:

Right.

Well, the sixteens would travel open till a preset at 240, approximate total 250 gpm in each loop.

In other words, I'm saying it would be actually putting in a q

l 1,000 gpm.

That's what they're set up to do, 250 per loop off the pumps.

HUNTER:

And what was the reasoning behind initiating SI?

FAUST:

You're taking off your n.ain coolant flow path, now, so our trend of thought was, at least mine was, you want water going in there.

You're trying to establish natural I

circulation, but to me we were also under situations that didn't really indicate that, to me, that we were gonna make it because we started to cavitate our pumps.

Its a lot of - the indication to me was a lot of voids, whatever you want to call'it, voiding out in the loops.

So we --

I'm not sure which -- it seemed like, try.

We were trying to establish circulation.

We had flow before we stopped it, so to us it wasn't inconveivable anyway.

HUNTER:

Who initiated the ESF?

FAUST:

Ed Fredrick.
