Dear Mr. Pollock:
Your letter to Chaiman Hendrie dated November 12, 1979 reouested a meeting with the NRC staff to discuss tne 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 vou indicated that you wished to receive additional infomation, which would be re-viewed bv your consultants, before establishing the meeting date and the
- narticicants for the Critical Mass Energy Project. You indicated that i vou requested a technical discussion of cladding swelling and rupture ncdels for LOCA analysis, a topic which has been the subject of considerable correspondence and meetings since the end of October 1979. In accordance i
with your request, I agreed to sord copies of recent infomation which I i think will be of help to you in understanding the present situation. In addition, I agreed to arranqe a mutually acceptable meeting in our l Bethesda offices when you indicate your readiness.
The renuested infomation is enclosed. Enclosure 1 lists the infomation beinq transnitted, and provides some comnentary which should be t=neficial l in understandino the content and status. When you have comleted your review of this infomation, please call te at 492-753 to arrance a Teeting date and time. If you have questions in the meantime, please call.

ENCLOSURE 1
}D Documents transmitted to Mr. Richard P. Pollock, Director, Critical Mass Energy Project on December 7,1979 Enclosure 2 A copy of the draf t report, " Cladding Swelling and Rupture Models for LOCA Analyses," UUREG-0630, by D. A. Powers and R. O. Meyer. This report differs in two ways from the information that was provided at the November 1,1979 meeting: (1) the typing of figure numbers and non-
. essential information (e.g., Table 1) has been completed, and (2) the important Section 4 showing comparisons with vendor models is included.
Approval to release the proprietary information in Section 4 had not been obtained on November 1,1979.
Enclosure 3 A summary dated November 20, 1979 of the public meeting held on Movember 1, 1979. This summary says why we thought there was a problem in the first pl-.ce and why, by the end of that day, we believed that there was no major safety problem. The last enclosure to that summary is a memorandum to the Commissioners providing more detail on the disposition of the problem.
