6 The ability to count the air samples collected should be demonstrate Questions in this area relate to the availability of sufficient counting systems to handle the expected large volume of samples as well as the susceptibility of such systems to being disabled by high ambient radiation fields. The inspectors reviewed documentation dated November 9, 1987 indicating that the licensee has set a limit on the amount of radioactivity on a charcoal cartridge and would not count cartridges above this limit. In addition, the licensee has purchased a shield for the gama spectrometry system located in the training center in order to provide shielding so that samples can be counted in the expected radiation field;. This sub-item is close The exact lines of authority during an accident should be designated, including the mechanisms that would be used to initiate sample collection and the assignment of priorities in counting those samples during an accident. The licensee has ordered air sampling equipment for the TSC, OSC, and ECC. The lead Radiological Controls representative in each center would direct sample collection from that center. This sub-iter.: is close (Closed) Unresolved Item (219/88-09-02): Compliance with Technical Specifications for airborne effluent sampling. The licensee is meeting ;

the Technical Specification requirements with respect to sampling every 48 hot rs when effluent monitors are declared inoperabl (SeeSection 3) This item is close . Effluents The responsibility for control of radioactive effluents from the site rests primarily with the Chemistry Department. Other groups have involvement in this area, such as I&C, which is responsible for process and effluent radiation monitor surveillance testin .1 Gaseous Radioactive Effluents The inspector reviewed the licensee's most recent submittal of the semi-annual effluent release report with respect to gaseous radioactive effluents. The report covered the period July 1 to December 31, 1987. No anomalies in the data were noted. The report appeared to be thorough and complete. In addition the inspector reviewed selected gaseous effluent data for the period January -

June, 1988. The following procedures in this area were also reviewed by the inspector:

,329.11- Turbine Building Ventilation System: Manual Sampling 83 Chemistry Surveillance Test Program 83 Surveillance / Compliance with 40 CFR 190 Off Site Dose Calculation Manual (00CM)

The data and procedures review indicated that the licensee has in place an adequate program for gaseous effluent sampling, analysis, surveillance, and reporting requirement The licensee uses the computer program EFFECTS to perform offsite dose assessment in order to demonstrate compliance with Technical Specification requirements using'0DCM methodology. The inspector using the gaseous effluent data for the period January 1,1988 to June 1,1988 performed hand calculations in order.to verify the dose calculations obtained by the licensee using the EFFECTS software. The results are:

Gamma Air Dose Stack Augmented Offgas Vent Licensee Result 4.5E-2 mrad 1.0E-2 mrad 1 NRC Result 4.4E-2 mrad 1.1E-2 mrad J Child Thyroid for Augmented Offgas Vent (Inhalation)

Licensee Result 5.4E-6 mrem NRC Result 5.7E-6 mrem l

The comparisons indicate good agreement. A review of the licensee's Jose calculations for 1988 to date indicate that the licensee is within Technical Specification Limit i

The inspector toured the facility and inspected the gaseous effluent monitors, selected ventilation systems and gaseous release pathways, and effluent monitor displays in the control room including the current monitor conversion factors. Presently the licensee is taking grab samples once every 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> at the Turbine Building Vent due to the lack of an effluent radiation monitor at the location. The licensee stated ;

that the monitor would be installed during the next refueling outage. No '

December 31, 1987.- No anomalies in the data were noted. .The report-appeared to be thorough and complete in this arer. In reviewing current data the inspector noted that no radioactive liquid releases had been made from the site for the period January 1 1 May 31, 1988. The following procedures in this area were also reviewed by the inspector:

82 Radiochemical Instrumentation: Liquid Radiation Monitoring 83 Radwaste System: Liquid Sampling 83 Radwaste System: Liquid Analysis and Disposition The data and procedures review-indicated that the licensee has in place an adequate program for liquid effluent sampling, analysis, surveillance and reporting requirements. The licensee is attempting to minimize routine liquid radioactive waste releases from the sit No routine liquid releases were-made during the third quarter of 1987 and, as noted above, no routine releases have been made through Ma for the year 1988. This is a noted strength of the licensee's progra The inspector noted that the licensee was effectively implementing the ODCM methodology for controlling ef fluent releases from the site, including trending of offsite doses and dose rate . Instrumentation The inspector toured the facility and examined the licensee's effluent radiation monitoring systems. Currently the liquid radwaste effluent monitor, the reactor building service water effident line monitor, and the turbine building ventilation monitor are not in service and are being operated under Tecnnical Specifications conditions which permit grab or additional sampling to meet the Technical Specification requirements. The licensee stated that the reactor building service water effluent line monitor and the turbine building ventilation noble gas monitor would be operable at the completion of the next refueling outag The inspector also reviewed the following procedures with respect to Technical Specification requirements for radioactive effluent and process radiation monitor checks, calibrations, and functional tests:

621.3.002 AE0G Radiation Monitor Test 621.3.003 Main Steam Line Radiation Monitor Test and Calibration 621.3.004 Process Radiation Monitors Test 621.3.009 MSL Radiation Monitor Front Panel Calibration 621.3.019 ARM / Process Radiation Monitoring Front Panel Test 621.3.021 A0G Ventilation Radiation Monitoring System Channel -

9-The inspector reviewed in detail the checks, calibrations, and functional tests of the main steam line and stack noble gas radiation monitors performed in 1987 and 1988 to date. The licensee is meeting the Technical Specification requirements with respect to these monitors and, in fact, is performing many of the surveillance tests more frequently than required by the Technic 1 Specification The inspector also reviewed the determination of the stack noble' gas conversion factor in which an actual stack gas sample is used to determine the effluent radiation monitor release rate. In addition the inspector reviewed selected effluent radiation monitor alarm set point These set points were determined in accordance with the methodolog specified in the ODCM. The inspector had no further questions in this are . Audits The inspector reviewed Quality Assurance audits of the gaseous and liquid radioactive effluent areas. The Technical Specifications require a audit of conformance to Technical Specification requirements at least once per 12 months and the ODCM and implementing procedures at least once per 24 months. The following audits of the chemistry department were reviewed:

-

Audit No. S-0C-86-10 performed 8-1-86 to 10-17-86

-

Audit No. S-0C-87-08 performed 7-13-87 to 10-7-87 These audits included the gaseous and liquid radioactive effluents areas. The ODCM has yet to be completely audited, although parts of the ODCM have been included in audits of the chemistry and radiological environmental monitoring areas. Discussions with. licensee personnel indicated that auditors were aware of the ODCM contents and bad incorporated various sections of the ODCM-into planned future audits, The inspector noted that the ODCM had not yet been in use for two year The inspector reviewed the master audit schedule and it appeared that the licensee would meet the Technical Specification requirements in this are The inspector noted that the audits which were conducted by a lead auditor appeared to be both quite thorough and of sufficient technical depth to adequately assess capabilities and performance-in the areas being audited. However, the inspector discussed with the licensee the inclusion of a technical specialist in the audit. The licensee stated that future audits would include a technicel specialis The inspector also reviewed activities performed by the Operational QA grou Periodic in-depth surveillances of Chemistry Department activities are performed by this group. Again, these Operational QA activities appeared to be quite good and of excellent technical depth, and were conducted by an individual with technical expertise in this are . -
