The 3UR Owners Group has directed General Clectric to take the lead in resolving this item with the NRC uith respect-to the LOCA analysis nodels.
The NRC staff was informed of this during the September 22, 1980 cirrification meeting in

acceptable.
Since General Electric performs the LOCA analyses for the Peach Botton Units, we also consider them to be the uost aporopriate party for the URC staff to work with in resolving the staff concerns related to small break LOCA models for BWRs.
i Accordingly, we-request that the NRC staff.connunicate directly with General Electric (contact Mr.
