Calhoun Station, and to the discussion of our findings with Dr. ,J. K. Gasper

and other members of your staff at the' conclusion of the-inspection on

October 19, 1990.

Areas examined during the inspection included portions of the liquid and

gaseous radioactive waste management programs and confirmatory dose

calculations of the offsite doses from radioactive waste effluents released to

the environment. Within these areas, the inspection consisted of selective

examination of procedures and representative records, interviews with

personnel, and observations by the inspectors.

The inspection findings are

documented in the enclosed inspection report.

Within the scope of the inspection, no violations or deviations were

l

identified. However, we identified some confirmatory calculation l disagreements

,

between your calculated offsite dose results and those calculated using our

~

PC-DOSE computer code. The problem appears to be in the computer codes used to

calculate your dose values.

The dose result disagreements'are discussed in

paragraph 7 (0 pen Item 285/9041-04) of the enclosed inspection report.

.
