96 much done. The question I have: is there any question for the staff here? Any questions for Mr.

Hopenfeld from members?

MEMBER ARMIJO: I'd like to ask with respect to the last presenter's comments about new data. Is the staff familiar with -- no, I'm asking the staff if they're aware of the new data that you referred to MR. FAIR: Hi. I'm John Fair with Division of Engineering who did a lot of the reviews on environmental fatigue.

Yes, we are. The new data is the latest Argonne data that was being applied in new design certifications. Basically the criteria they're using ins license renewal was criteria that was developed quite, a while back, and we made a decision at that time that we would, as criteria, we would maintain that criteria because there were a lot of applications in process. So we didn't want to keep changing the rules as these people were putting in new applications. And a lot of the criteria had changed and was massaged over the years.

Actually if you go back and look at the latest, criteria we're applying to new reactors., it's not as conservative as the old criteria because we NEAL R. GROSS COURT REPORTERS AND TRANSCRIBERS 1323 RHODE ISLAND AVE., N.W.

97 changed the basis for deriving the curves. So if you go and look at the Fen factors themselves using the new criteria, they'll generally be lower.

MEMBER ARMIJO: Okay. Thank you.

VICE CHAIRMAN BONACA: Any other questions?

If not, Mr. Chairman, I'll turn the meeting.back to you.

CHAIRMAN SHACK: Okay. Well, it's five minutes late. I'd like to take a break now. I thank the presenters, staff and the industry, for a good presentation, I think, very informative and Mr.

Hopenfeld for his comments.

We're slated for 15 minutes. So we'll be back at ten of.

(Whereupon, the foregoing matter went off the record at 10:35 a.m. and went back on the record at 10:55 a.m.)

CHAIRMAN SHACK: The next topic is a draft final Revision 1 to Regulatory Guide 1.45, "Guidance on Monitoring and Responding to Reactor Coolant System Leakage, and, Sam, I think you're going to take us through that.
