, -' WPPSS NUCLEAR PROJECT NO. 3 - UNITS 3 & 5 l* DOCKET NOS. 50-508 & 50-509 METEOROLOGY The plant site, located in the Chehalis River Valley of western Washington 26 miles west-southwest of Olympia, is in a region where atmospheric dispersion conditions are about average for the western United States.

, A description of meteorological conditions at the site, including the climatology of the region, local meteorological conditions, and expected severe weather, is presented in Section 2.6 of the Draf t Environmental

Statement for the plant issued in February 1975.

The Skagit plant design is consistent with the Regulatory Design Basis Tornado model (300 miles / hour) which is sufficient for this region of the United States.

The applicant has provided joint frequency distributions of wind speed and direction by atmospheric stability (based on vertical temperature difference) collected onsite during the one year period from May 1973 through April 1974. Atmospheric. dispersion estimates were based on wind direction and speed measured at the 10-meter level and vertical temperature difference between the 10- and 60- meter levels. An evaluation of short-term accidental releases frcm plant buildings and vents, assuming a ground-level release with a building wake factor, cA, of 1500m2 was made using the meteorological data described above and the diffusion i model described in Regulatory Guide 1.4.

A comparison of the short-term (0-2 hour) ' relative concentration (X/Q) value calculated for this site with similar values calculated by the Regulatory staff for over 40 other sites indicates that dispersion conditions at this site are better than at 30% of the other sites.

We conclude that there are no meteorological characteristics that would preclude site acceptability.
