l REQUEGT FOR ADDITICI;AL II.TORMATI0I; WASHIIiGTOI; PUBLIC POWER SUPPLY SYSTEM HANFORD NO. 2 DOCEET IiO. 50-397 Document BITdL - 1350 entitled Site Safety Analycis, Fact Flux Test Facility includes evidence in the form of Figures (2.22, C-1, C-2) and narrative (page 2.20) that the " difference in flow patterns between the 200 area plateau and the river are evident by ecmparison of wind reses for Statien 8 (the Meteorology Tower in the 200 area) and Statienc 5, 9, and 17 (300 aren)". The Hanford I;o. 2 PGAR specifies in Section 2.3.1.1 that differences in meteorology between the metrorological tower and the prcpeced site will be investigated in part by data from the FE F tite (3 miles from the Hanford I;o. 2 site). It is understcod that there is and hac been in existence for seme time an anenameter at a locaticn atout 3 miles WIT 4 cf the propxed site. Are there data y available frcn this ctation which might offer evidence ac to whether the prcposed cite winds are more like the plateau (200 Area) er river (300 area) regimes? If co, summarize these data.
Include information defining significant periods of miccing data during the cummariced period. State your conclusions reculting frcm analysis of these data.
Provide, for a repre.entative period of at least one year, joint frequer.cy distributions of wind speed and direction by AT stability clacs. Ihe AT classes should be as specified in Table 2 of Safety Guide 2; oncite Met eorological Progrre.c. The AT measurements should be based en
e h
. en temperatures measured at 50 ft and 150, 200, or 250 f t on the existing Hanford bl0-foot meteorology tower. The levels of measurement specified in this request are not intended to specify levels to be employed in your proposed data collection program described in Section 2.3.3 of the PSAR.
In this regard, your attention is called to Section C, Regulatory Pcsition of the appended Safety Guide 23.
Sub-section C.1 of Safety Guide 23 mentions the inclusion of humidity measurement instrumentation at sites where there is a potential for fcgging or icing due to operation of cooling tcwers. Have such measure-ments been considered in your proposed data collection program?
Define "same direction" as employed in generating persistance prcbability Figures 2.3-11 and 2.3-12 of your PS AR.
Specify the source of your upper air observations presented in Table 2.3-5 of your PSAR.
