LWA TESTIMONT WPPSS NUCLEAR PROJECTS NOS.1 & 4 DCCKET NU:OERS 50-460 50-513 METEOROLOGY
~
The-plant site, located in the Columbia Basin area of western Washington about eight miles nor:h of Richland on the Hanford reservation, is in a region where atmospherite dispersion conditions are abcut average for the western United States, A description of meteorolcgical conditions at the site, including the climatology of the region, local meteorology conditions, and expected severe weather..is presented in Section 2.6 of the Draf t Environmental Statement for the plant issued in December 1974.
The UPPSS units 1 & 4 plant design is consistant with the Regulatory Tornado Model (240 milea/ hour maxinum wind speed) which is sufficient
.for this region of the. Un.ited States.
' The applicant has provided joint frequency distributions of wind speed and direction by atmospberic stchility (based on vertical temperature difference) collected at the Hanford Meteorological Statioa 14 miles to the northwest, during the 16 year period from 1955 through 1970. Atmos-pheric disparzion estimates were based en wind direction and speed measured et the 200-f t level and reduced to represent conditions at the 33-f t level and stability determined by the vertical temperature differ-ence between the 50- and 250-ft levels on the tower. An evaluation of short-tere accidental teleases froa plant buildings and vents, assuming a ground-level release with a building uake factor, cA, of 1048 m' was made using the receorolodical data described above and the diffusion model
' des:ribed in Regulatory Guida 1.4.
A comparison of the short-tern (0-2'hr) relative ccncentration (X/Q) value estimated for the WPPSS Nuclear Project Number 1 site with cialler values calculatei by the Regulatory staff for over 40 9ther sites indicates that the dispersion conditions at the WPPSS 1 S. 4 eite are better than 65% of the other sites. Site dispersica esti-j mates will be confirmed using a full year of onsite data to be provided by the applicant upon completion of the annual data collection cycle.
We conclude that there are no ecteorological characteristics that would preclude site capability.
