• Attended the exit interview on August 28, 1987 2.0 Action on Previously Identified Findings 2.1 (Closed) Inspector Follow-Up Item (50-245/86-08-01; 50-336/86-08-01)

Audits of changes to Technical Specifications regarding effluents had not been completed. The inspector reviewed an audit of this area conducted in 1986. Major portions were completed. This item is close .2 (Closed) Inspector Follow-Up Item (50-245/86-08-02; 50-336/86-08-02). Review revisions to procedures for periodic surveillance tests to be performed. Procedures ACP-QA-9.02 A and ACP-QA-9.02 B were reviewed by the inspector and found satisfactor This item is close .3 (Closed) Inspector Follow-Up Item (50-245/86-08-04). Personnel at Unit One were not aware of calibration procedure and method for the steam jet air ejector radiation monito The inspector interviewed Unit One Chemistry personnel and found them knowledgeable of the calibration methodology. This item is close .4 (Closed) Inspector Follow-Up Item (50-245/86-11-01; 50-336/86-11-01)

Addition of Fe-55 and intercomparing all counting geometries routinely used in the laborator The inspector reviewed chemistry procedures and results of analyses and found that Fe-55 was added and geometries other than liquid being implemented. The inspector noted that although the procedure specifies a frequency of intercomparisons semiannually, the licensee was performing them on a monthly basi __ _ . _ _

3.0 Chemistry The organizational structure in the chemistry. department _is. divided into groups with responsibilities for each facility. The Chemistry Supervisor has the.overall responsibility and authority for the program. Assistant Chemistry Supervisors oversee the day to day activities for each unit and for program implementatio The licensee's radiochemistry program was reviewed through discussions with~ chemistry personnel, review of applicable procedures and radioactive effluent release data and permits. Procedures were established and implemented for liquid and gaseous wastes and reactor coolant as required by Technical Specifications. - Surveillance requirements are established in administrative. procedures.ACP-QA-9.02 A and ACP-QA-9.02 B for Units One_and Two respectivel The inspector reviewed release information and performed a spot check on the calculated doses as a verification, using the equations in the Offsite Dose Calculation Manual (0DCM). The ODCM was well stated and provided details and bases for the calculation methodolog With regard to vendor supplied analyses of Sr-89, Sr-90, and Fe-55, the inspector noted that the licensee controls vendor activities through a sample _QA program. The intercomparison QA program has been expanded to utilize all of the typcs of ' geometries routinely employed in radioanalytical measurements and the analyses are conducted monthl The procedure stipulates a sample frequency twice a yea Within the scope of this review, no problems were note .0 Audits The inspector reviewed audits germane to the radioactive effluents control program and found them comprehensive and technically complet The Radiological Assessment Branch (RAB) is due to perform an audit of-setpoint methodology and program implementation in the fourth quarter of 1987. The recent audit performed on the Radiological and Environmental Offsite Dose Calculation Manual (REM 0DCM) on behalf of the Nuclear Review Board (NRB), No. A-24001, 10/86, was reviewed by the inspector. The report included several findings which were adequately addressed in a timely manne Within the scope of this review, no violations were note .0 Radiation Monitoring System The inspector reviewed the gaseous and liquid effluent radiation monitoring system with respect to Technical Specification requirements for calibration and functional / channel checks. The inspector reviewed selected procedures and accompanying records for calibration and
