In Table SA-1, BVPS-2 refers to a plant s imilar in design to BVPS-2 where anal ys es and/or tes t s were c on-duc t ed. These tes ts included Natural Circulation Test Report s which clearly demons trated the ability to initiate a controlled natural circulation cooldown in a Westinghouse three-loop plant. The refo re,
because of the clos e similarity, BVPS-2 does not plan to repe at a Natural Circulation Test at BVPS-2.
ITEM 2: Verification of Supplies of Auxiliary Feedwater to Support Cooldown Method:
