Review Oconee Unit 1 reactor coolant flow evaluation (B&W NSS).
Oconee Unit 1 was dnsigned for a minimum reactor coolant flow rate of 131.32 x 105 pounds per hour at full rated power.
Partially because of internal changes resulting from redet,ign and refabrication, the reactor coolant flow rate has been s
measured to be 140.34 x lo pounds per hour at 75% power.
For safety analysin purposes, Duke Power Company has established 134.34 x 106 pounds per hour as the minimum flow rate at rated power to meet DNBR requirements in lieu of the 131.32 x 108 pounds per hour FSAR value.
The =nvim=- reactor coolant system flow rate based upon fuel assembly lif t li:2itations remains at 110.8% of the FSAR minimum design flow rate (131.32 x lbb lb/hr).
g.
We request that TR review this matter to assure us that the higher flow rate and method of analysis are acceptable prior to the prospective decision date (October 4,1973) for Oconee Unit 2 since this matter influences our Oconee Unit 2 decision.
