I oLc z1 G73 J. P. Stohr, Chief, Environmental Protection and Special Programs Section, Directorate of Regulatory Operations, Region I Inspector's Evaluation RO Inspection Report No. 50-219/7319, Meteorology i:
The portion of the inspection referenced above consisted of a detailed review of the licensee's meteorological program.
No items of violation were found during this inspection because there were no Technical Specifications dealing with this program. OC had sub-mitted a supplement to their application for their license in which they indicated they will satisfy Safety Guide 23 when their new tower is con-structed and new equipment is installed and operational. Meanwhile, there are a number of areas in the present program which are in nonconform-ance with the Guide.
1.
The Ouide requires a redundancy of recorders and sensors, or fre-quant inspections of these devices to insure 90% data recovery.
00 had no redundancy in this manner and inspected these devices 3 times weekly despite finding a high frequency of recorder fail-ures over the past several weeks.
2.
Safety Guide 23 says that recorders for wind speed and direction, and for temperature differences should be located in the reactor control room for use during reactor operations. The only recorders for this data are located in the meteorology shack at the tower.
Only the wind speed and direction at the 400 ft level are even gpg indicated (but not recorded) in the control room. Temperature differences were not indicated in the control room.
3.
The Guide indicates that a semi-annual calibration of instruments should be done. OC had been calibrating on an annual basis.
(I noted the supplement to the operating license did indicate OC would calibrate semi-annually af ter the new tower is operational.)
4.
The Guide calls -for monthly or seasonal and annual joint frequency distributions of wind speed and wind direction by atmospheric stability classes to be compiled from basic reduced data. OC sent 4
the recorder charts to Digital Graphics for reduction and key punching.
It was then sent to Picker and Lowe to be used in the 6 month operating report. OC had not obtained a copy of their basic reduced data, which did not even appear in the 6 month reports.
Picker and Lowe used the Wind Speed and Wind Direction data from the 400 foot level and that was all.
These compilations were not made according to Stability Class.
It appeared that what other information was collected, was not used at all.

- 5. - The_ data that was compiled (in the 6 month renort) was not adequate to allow either the licensee _or the'AEC staff to evaluate the Eit '
meteorological conditions and ' determine the atmospheric diffusion factors (X/Q), for accidental or annual releases.of ef fluents such that realistic'estimtes of'resulting doses.co the surrounding population could be.made in accordance with the Guide. No attempt was made by the licensee to come up with such estimates.
i In' addition,-when the Technical Specifications are updated to in-clude the meteorology program, (such as, inclusion of the section 4
developed'in Supplement 4 to the application for an operating

license).the type of data reduction and compilation to be done by.
1 the licensee _ought to'be spelled out. Data compilation should be according to the format suggested by Safety Guide 23, including wind frequencies by Stability Class, hours of data not recovered, etc. Meteorological information to be included in the 6 month report should also be spelled out.
