April 24, 1979 NRC I&E Interview EUNTER:

Okay.

Is there a time where you then, during the first eight hours, excuse me, during the first four hours or five hours, you stayed on during that day, I guess, and worked.

But, during that first four or five hours, was there a time you realized that you could have had a loss-of-coolant or that you were having a loss-of-coolant?

ZEWE:

Certainly.

Once we isolated the electromatic block valve, it hit me like a ton of bricks that that's where the water was going and that's exactly what caused the high level in the pressurizar.

I had--well, we had looked at the discharge temperatures on the relief valves earlier and they really didn't seem like they were high to where the valve was open and I had indication on the valve that the valve was not still open.
