Dear Mr. Pollock:
Your letter to Chairman Hendrie dated November 12, 1979 requested a meeting with the NRC staff to discuss the basis of NRC's ECCS analysis.
I called you on November 29th for the purpose of establishing a date and agenda for the meeting.
In the telephone conversation you indicated that you wished to receive additional information, which would be re-viewed by your consultants, before establishing the meeting date and the participants for the Critical Mass Energy Project. You indicated that you requested a technical discussion of cladding swelling and rupture models for LOCA analysis, a topic which has been the subject of considerable correspondence and meetings since the end of October 1979.
In accordance with your request, I agreed to send copies of recent information which I think will be of help to you in understanding the present situation.
In addition, I agreed to arringe a mutually acceptable meeting in our Bethesda offices when you indicate your readiness.
The requested information is enclosed. Enclosure 1 lists the information being transmitted, and provides some commentary which should be beneficial in understanding the content and status. When you have completed your review of this information, please call me at 492-7258 to arrange a meeting date and time.
If you have questions in the meantime, please call.
Very truly your7, M
Richard P. Denise, Acting Assistant Director for Reactor Safety Division of Systems Safety
