Site Design Parameters

Design assumes site parameters representative of a reasonable number of potential plant site locations in the U.S. A summary of the parameters is in FSAR Table 2.0-1 and provided in following slides.

COL Item 2.0-1: demonstrate site-specific characteristics are bounded by design parameters specified in Table 2.0-1. If not bounded, demonstrate acceptability of site-specific values.
