FSAR.

A flow rate of 106.5% of design-flow is 2.

used rather than the 107.6% previously used.

The FLAME computer-code was used in 3.

revised to incorporate a projected fuel rod low penalty based on B&W 1etter dated September 10, 1976.

A June 15, 1977 date was selected to permit an orderly issuance of-this package prior to Oconee Unit 1 startup, which appears to be
