Third Supplement dated July 31, 1967 -
i.i.......... . . .:I Prepared by Environmental Meteorology Branch Institute for Atmospheric Sciences Environmental Science Services Administration August 28, 1967 In regard to question VII.G.5, it is obvious f rom the comparison made by the applicant that there is very little dif ference beyond the first 300 meters between using a virtual point source or a volumetric source technique to account for added building-induced diffusion. It should be pointed out that both techniques are an empirical means to account for a phenomena which is not clearly understood but which i s observed. For comparative purposes it is interesting to note the ratio between con:entrations without accounting for building turbulence and the volumetric approach. The table below shows the Diablo Canyon calculations compared to recent field tests at the National Reactor Testing Station conducted under inversion conditions and moderate wind speeds (u = 6.3 m/ sec).
,Di st ance (meters) Diablo Canvon EBR-II Tests 100 3.5 200 4.2 300 9.6 400 6.2 3.9 6?0 3.2 700 3.2 800 2.8 1000 2.3 Extrapolating the results, one would conclude that an added dilution fa: tor of 2.8 is reasonable at the site boundary of 800 m.
