i ENCLOSURE Point Beach, Units 1 and 2, Technical Specification Changes 490.0 Reactor Fuels Section, Core Performance Branch 490.1 Describe what margins were used to offset the reduction in DNBR due to fuel rod bowir.g.
Has NRC approved these margins for Point Beach applications?
Ii not, please provide the necessary justification.
l 490.2 Are the margins used to offset rod bowing DNBR penalties employed solely for this purpose? If not, please provide justification for using these margins more than once.
490.3 The reduction in DNBR due to rod bowing for the loss-of-flow transient and N-1 loop operation is greater than the reduction in DNBR for other conditions.
Is additional available margin used, or is the calculated limiting DNBR sufficiently large to offset this incremental penalty.
490.4 Amend the basis of the technical specifications to identify each generic or plant-specific margin that has been used to offset the reduction in DNBR due to rod bowing.
Also reference either the source or approval of each generic margin.
