Comments on Shoreham Nuclear Power Station Long Island Lighting Company Preliminary Safety Analysis Repcrt Amendments 4 and 5 dated April 28, 1969 Prepared by Air Resources Environmental Laboratory Environmental Science Services Administration June 9, 1969 The meteorological data presented in Amendment 4 is identical to the information presented in the original submission. Thus, our general comments cf August 16, 1968 are still pertinent to the latest report.

The meteorological conditions used for the accident dose analyses (page XIV-4-1) are reasonably conservative for releases up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

We do not agree with the wind constancy approach in deciding the appropriate diffusion parameters for the 31-day release. A joint monthly wind rose and turbulence category distribution would be more pertinent. For example, the Brookhaven data show that during the su=mer ,

months inversion conditions exist about 50% of the time and that of l these conditions,13% occur in a 200 sector from the southwest, resulting in a joint frequency of about 6.5%. However, these data are based on a 10-year average. It is not unreasonable to assume that for an dadividual " worst" month, the inversion summer wirei rose could show a 25% frequency in the 200 sector from the southwest, for a joint frequency of 12 5% (25% x 50%). Thus assuming Pasquill Type F diffusion rates and a2m/seewindspeed w l to be 7.5 x 10-5 see,m->g compute at the the " worst" ite boundary. month average This compares core entration with our j computation of 1.5 x 10-5 cee using the applicant's lapse conditions. i l

As was the case in our previous comments it is difficult to check dose calculations because no relative diffusion values are listed.
