Dear Dr. Hendrie:
This refers to the letter of September 14, 1972, from A. Schwencer, Chief, Pressurized Water Reactors Branch No. 4, Directorate of Licensing, requesting comments on the following:

Sincerely,

silver. spring, Maryland 20910 Comments on Arkansas Nuclear One, Unit 1 Arkansas Power and Light Company Final Safety Analysis Report Amendment No. 29 dated 9/8/72 Prepared by Air Resources 2nvironmental Laboratory National Oceanic and Atmospheric Administration January 11, 1973 The basis for our most recent evaluation of the diffusion characteristics of the site is the data presented in tables 2. A-30 and 31 of Amendment No. 29.
These data cover a one-year period, approximately half of which winds were measured at 190 ft. and the remainder at 40 ft.
Because of effluent emission from rooftop vents, we have assumed a ground release and therefore have reduced the 190 f t. wind speeds to an equivalent 40-f t.
level by means of the power law function suggested in the ASME Guide.
For the short-ters (0-2 hours) release we have estimated from the joint free.uency of wind speed, direction and temperature gradient in the vertical that a relative concentration of 7 x 10-4 see m-3 will be exceeded five per-cent of the time at the minimum exclusion distance of 1046 m.
This assumes 2
a ground source and a building wake f actor of cA = 1100 m. The concentra-tion value is in close agreement with the value shown by the applicant in figure 2A-16.
We have not estimated concentrations for periods from 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> to 30 days since the meteorological data are not presented for these periods.
For the average annual relative concentration we have estimated that the maximum value occurs with winds from the east.
From the data compilation shown in tables 2.A-30 and 31 we estimate a 24 percent frequency of winds from the east' divided among Pasquill types F, D and B at a frequency of 12, 8 and 4 percent and speeds of 2, 3 and 3 m/sec, respectively.
The resulting average annual relative concentration at 1046 m is 1 x 10-5 see m-3,
