p-Replace existing Section 9.2.6.4.2.2 with the following:
9.2.6.4.2.2 Natural evaporation of the Spray Pond was based on the design meteorology of Section 9.2.6.4.1 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.
