?'IIISTO?it MO. : 01-62 FISPONSIBLE IP, RICH: LURS4 Ua have reviewed the 9ections concerning netcorology of the tapSS-2 71nal Safety.,Analynio Report and have f,oind it acceptable. Encleced are several questions which we ask that you fortrard to the Broject.

John Coll, of ny section, prepared these questions.

He wish to cottend the Project for its very connlete and thorough report on meteorolog. Please pass our cc:mondation on to the Project.

FSAR ACCEPTANCE REVIEW - METEOROLOGY WPPSS NUCLEAR PROJECT NO. 2 DOCKET No. 50-397 372.0 . Meteorology (2.3) 372.0 Regional Climatology (2.3.1) 95% complete 372.1 Figure 2.3-5, based on your Reference 16 (Hilst and Nickola,1959), gives (2.3.1.2) average mass of dust per cubic foot varying with height at Hanford on 11 August 1955. Figure 2.3-6, based en your Reference 17 (Sehmel and Lloyd, 1972),provides airborne dust concentrations at four feet above the ground as a function of average air velocity. One data point of this figure is from a dust storm of 11 January 1972.

a) Reference 16 does not describe the meteorological conditions occurring during data sampling. Describe these conditions.

i Discuss whether Figure 2.3-5 represents average or extreme particulate loading conditions for the site region.

b) Describe the magnitude of the dust storm of 11 January 1972, including visibility during the storm and an estimate of expected return-period.

c) Surmise the vertical profile of particulate size and total mass

,cencentrations for the 11 January 1972 dust storm, and provide the bases for your estimate.

90% Complete 372.3 Provide a description of the meteorological monitoring program which (2.3.3) will exist during plant operation.

372.4 For each measured meteorological parameter, provide the total (sensor, (2.3.3.1) recorder, analysis, etc.) accuracy.

1 372.5 Provide the appropriate units for all variables used in Equations (2.3.4.2) 3, 4, 5, 6, and 7.

372.0 Long-Term (Routine) Diffusion Estimates (2.3.5) 85% Complete 372.6 You selected a Gaussian diffusion model to estimate offsite gaseous (2.3.5) concentrations. Justify its use for the WNP-2 site. As discussed in Regulatory Guide 1.111, consider its applicability both for within a few miles of the site and for distances out to 50 miles. Discuss the effects of deviations from the implied assumptions of the model (such as flat, homogeneous terrain, non-variability of the airflow, single-station analysis) that are necessary due to area-specific characteristics. Such characteristics could include the influence of topographic features on the airflow, preferred airflow paths, local diurnal wind patterns, and other spatial and temporal variations of the airflow. Provide any adjustments n;eded to Equation 1 which may be necessary to prevent misrepresentation of actual atmospheric transport and diffusion characteristics which could result in sub-stantial underestimates of actual exposure to an individual or population. , ,
