Documents for Public Meeting on LOCA Frequency and Jet Formation Date: Friday, May 18, 2012 11:12:58 PM Attachments: UT_May2012_CFD_FINAL.docx loca-hybrid-final.pdf

Balwant, Please find attached two documents we would like to discuss with the Staff in a Public Meeting. The documents are on recently completed work in LOCA frequency and Jet Formation.

We would like the meeting to focus primarily on the new methodology we have introduced in the LOCA frequency application in the GSI-191 context. We believe in this new method, we have addressed the Staff concerns associated with accounting for degradation mechanisms while also maintaining the NUREG 1829 frequencies. Also new in this method from last year is accounting for the epistemic uncertainties, and we are accurately preserving the 5th percentile, Median, and 95th percentile parameters which we concerns expressed by Bob Tregoning.

I would appreciate it if we could have the meeting scheduled shortly afterJune 10 as I will not be in the country after next week, returning June 9. It is possible for me to join a teleconference however it will be extremely expensive to do so while out of the country.

Thank you in advance for your help in scheduling this meeting.

Ernie Kee
