SUBJECT:
SAFETY EVALUATION REPORT--LICEilSE AMEN 0 MENT APPLICATION FOR AUTHORIZATION TO SURVEY THE REMOVABLE URANIUM CONTAMINATION BY COUNTING ALPHA ACTIVITY ONLY, LICENSE NO. SilM-1067, AMENDMENT N0. 21 REVIEWER:
A. L. Soong I.
Backoround The existing surface contamination control program conducted by Combustion Engineering (CE) at the Windsor Facility includes the routine survey of the areas where a potential for uranium contamination exists for both alpha and beta counting modes.
By letter dated September 21, 1979, CE requested authorization to use only the alpha counting mode in routine surveys for determining the removable uranium contamination levels.
II.
Discussion A.
Radiation Safety Uranium materials that have been handled in a uranium fuel fabrication plant may, in theory, be detected by surveying for either alpha or beta acti vi ties.
However, the most abundant radionuclides in the uranium are alpna emitters, therefore, alpha surveys are related more directly to potential personnel hazards than beta surveys.
Regulatcry Guide 8.24 also calls for alpha surveys alone in determining the level of removable uranium contaminatian.
The amendment application was discussed with Mr. Percy Clemons of Region I. IE Radiation Safety Inspector for the CE Facility. He foresaw no safety ; elated problem to the change in method for surface contamination control.

2 B.
Nuclear Criticality Safety No significant effect on the nuclear criticality safety of the operation should result from the modification to the surface contamination control program.
C.
Environmental Effects No significant environmental effect should result from the modification to the surface contamination control program.
III.
Conclusion The modification to the surface contamination control program is adequate for the protection of the health and safety of operating personnel, the public and the environment.
Issuance of the license amendment is recommended.
