Replace existing Section 9.2.6.4.2.2 with the fo1100ing:
9.2.6.4.2.2 Natural evaporation of the Spray Pond was based on the meteorology selected in accordance with Regulatory Guide 1.27, Revision 2, and a-constant pond surface area of 9.6 acres. The water loss due to natural evaporation is shown in Table 9.2-13.
This is conservative since the average surface area over the 30-day accident scenario is-less than 9.6 acres, and the effect of the sprays suppressing evaporation is not taken into account.
The evaporation calculation was based on the methodology of Reference 9.2-5.
