Denotes those present at the exit interview on August 20,199 Other licensee employees were contacted and interviewed during this inspectio .0 Purnose The purpose of this inspection was to ensure that the licensee effectively controls, quantifies, and monitors releases of radioactive materials in liquids, gases, and particulates according to Technical Specifications, Offsite Dose Calculation Manual (ODCM), and appropriate procedures during normal and emergency operatio .0 Licensee's Actions on Previousiv Identified items (Closed) Violation (50-219/90-13-01). Inoperable radwaste overboard discharge radiation monitor. During the review of the radwaste overboard discharge (liquid effluent) radiation monitor, the inspector evaluated the licensee's efforts to calibrate and return the liquid effluent monitor to service. The inspector determined that (1)

the primary calibration was performed appropriately, and (2) the secondary calibration was performed appropriately. This item is close .0 Management Controls Organization and Program Changes The inspector reviewed the organization and administration of the Radioactive Effluent Control Programs (RECP) and discussed with the licensee any changes since the last inspection conducted in May 1992. Overall, there have been no significant changes in the oversight of the RECP since the last inspection, however, in April 1993, the responsibility for the radiation monitoring systems was shifted from Plant Engineering (Oyster Creek Site) to Chemistry / Fire Protection System Engineering, Technical Functions (Corporate Office). (See Section 6.0 of this report for details.) Ouality Assurance Audits The inspector reviewed Audit Report No. S-OC-93-08, "Offsite Dose Calculation Manual / Radiological Environmental Monitoring Program" as part of the evaluation of the implementation of Section 6.5.3 of Technical Specification (TS) requirement The audit was conducted by the Quality Assurance Department during May 26-June 29,1993 and the report was issued on August 3,1993. The ODCM audit covered aspects of the effluent program including procedures / document control, technical specification surveillance / effluent analysis, dose

assessment / reports, and records. The audit was of adequate technical depth to assess the RECP. No significant findings impacting the radioactive effluent control programs were note .3 Review of the Semiannual Effluent Release Reoorts The inspector reviewed the semiannual radioactive effluent release reports for 1992 and determined that the licensee met the TS reporting requirement These reports provided total released radioactivity for liquid and gaseous effluents. These reports also provided descriptions of any inoperable effluent radiation monitoring systems and any changes in the Offsite Dose Calculation Manual (ODCM) as required by TS. The inspector noted that the service water radiation monitor was out-of-service repeatedly during 1992 until

'

modifications in March 1993 made the system operable. Also, the overboard discharge monitor was reported out-of-service until August 1992. During the entire reporting interval of January 1 - June 30,1992, there was one minor unplanned liquid release of 0.088 microcuries of silver-110m. This release was within regulatory limits. During the reporting interval of July 1 -

December 30,1992, the augmented offgas monitor was declared out-of-service for two and one-half weeks prior to the outage and remained in this status for longer than thirty days after the outage. The monitor was declared operable in -

March 1993. Grab sampling was performed as required by the TS for the monitor. There were no liquid releases during this time interva There were no significant changes to the ODCM in 1992, nor during the first half of 1993. No obvious anomalous measurements, omissions or trends were ;

The inspector noted that the procedures were detailed and well written. There were no planned liquid radwaste effluent releases during 1992 because of the licensee's program to reduce the routine release of radioactive liquid from the site during normal operation. This aspect of the RECP continues to be excellen ;

The inspector reviewed gaseous effluent controls via the weekly iodine and particulate sample results and the monthly gaseous grab sample results for noble gases. The reviewed results indicated that samples were collected as required and no anomalous measurements were identified during this inspectio Based on the above reviews and discussion with the licensee, the inspector determined that the licensee met the TS requirement .0 Radiation Monitoring Systems (RMS)

The inspector reviewed the calibration procedures and the most recent calibration results for the following effluent and process RMS to determine the implementation of requirements in Sections 3.15 and 4.15 of the T ]

• Service Water Radiation Monitor i

• Radwaste Overboard Discharge Radiation Monitor  !

(Radioactive Liquid Effluent Monitor)

eTurbine Building Sump No.1-5 Monitor

• Main Steam Line Monitors

• Air Ejector Offgas Monitors

• Stack Noble Gas Monitors (RAGEMS, Low and High Range)

• Turbine Building Noble Gas Monitors (RAGEMS, Low and High Range)

• Augmented Off Gas (AOG) Building Ventilation Noble Gas Monitor In April 1993, the responsibility for maintaining the RMS was shifted from Plant Engineering (Oyster Creek Site) to Chemistry / Fire Protection (CFP) System Engineering, Technical Functions (Corporate Office). The Plant Engineer was renamed System Engineer Assistant and remains on site. The System Engineer Assistant is the responsible individual for the RMS, with the exception of the AOG RM The inspector toured the facility to examine the above monitors with the System Engineer Assistant. All the listed monitors, with the exception of the Air Ejector and Main Steam Line Monitors, were examined to determine if the monitors were operational and maintained. The latter were not easily accessible due to plant operations, but were functioning at the time of the inspection. The AOG Ventilation -

RMS and the Stack and Turbine Building Radioactive Gaseous Effluent Monitor System (RAGEMS) were functioning at the time of the inspection. The Turbine Building Sump No.1-5 Monitor, installed to protect against a possible inadvertent

.

.-

release from the sump to the environment, was out-of-service. No interim samples were required because there were no liquid releases through this pathway. The Service Water monitor had a history of frequent failures. Several of these failures were longer than thirty days and were caused by the growth of algae in th monitoring chamber. The inspector noted that the licensee had installed a new sample line from the Service Water Header so that flow through the monitor would be maintained. The Service Water Monitor was operable at the time of the inspectio The Radwaste Overboard Discharge Monitor was operable at the time of the inspectio During the review of the calibration procedures and results of the above RMS, the inspector noted that the results were within the licensee's acceptance criteri However, the inspector noted that weaknesses in the secondary calibration continue The sources used for calibration were corrected for decay if applicable, then counted three times and averaged. This value was then compared to the decay corrected value 20%. The licensee did not verify the linearity or calibration factor ( Ci/cc/ cpm)

for these radiation monitors using the data and statistical analyses, such as linear regression. (See Inspection Report 50-219/92-11 for additional details.) The inspector discussed with the licensee the following method for calibratio The primary calibration for the RMS is performed using at least three known concentrations of radioactivity (NIST traceable sources). From these results, linearity and the conversion factor ( Ci/cc/ cpm) are determined. The secondary calibration is performed using at least three solid button sources of different strengths (i.e., Cs-137:

0.005, 0.1, 0.4, 1.1 pCi, etc.). The linearity and the secondary conversion factor (pCi/ cpm) are calculated from the calibration results. This secondary conversion factor is verified during subsequent calibrations using at least three solid button sources. The results of each subsequent calibration when plotted should yield the same conversion factor as the secondary conversion factor. Then one can make a safe assumption that the primary conversion factor has not changed. The licensee stated that this area would be reevaluated and appropriate actions would be take The inspector determined that (1) primary calibrations were properly performed for the above monitors, and (2) use of the secondary calibration results could be related to the primary calibration, as described in the above paragrap Based on the above inspection and discussions with licensee representatives, including a tour of the facility, and the subsequent meeting, the inspector determined that the methods currently used by the licensee to calibrate the above monitors were acceptabl l
