Inspector Observations The following are observations the NRC inspectors discussed with the licensee during the exit interview on March 3, 1989. These observations are not violations, deviations, unresolved items, or open items. These observations were identified for licensee consideration for program improvement, but the observations have no specific regulatory .l requirements. The following observations are identified in paragraph 3 of ,

this repor The licensee stated that these observations would be '

evaluated, Monitor Tank Release Permits - The licensee was no longer requiring a supervisory review and approval signature on the liquid radwaste effluent release permits prior to submitting the release permits to the control room for performance of the liquid discharge (see paragraph 3). Liquid Radwaste Ef fluent Release Data Review - The licensee's Plant Chemist had not completed a review of liquid radwaste effluent release reports in a timely manner following the completion of the liquid releases (see paragraph 3).

3 Liquids and Liquid Wastes (84750, 84523, 84723)

The NRC inspectors reviewed the licensee's liquid radioactive waste effluent program including: liquid radwaste system construction and installation, liquid radwaste sampling, procedures for liquid radwaste and effluent systems, reactor coolant and secondary water quality, and audits and surveillance to determine agreement with commitments in Chapters 4, 9, 11, and 12 of the Updated Safety Analysis Report (USAR) and the requirements in Sections 2.1, 2.9, 2.20, 3.12, 5.5, and 5.8 of the Technical Specifications (TS).

The NRC inspectors reviewed the licensee's implementation of the Radiological Effluent Technical Specifications (RETS) and Offsite Dose Calculation Manual (0DCM) to ensure agreement with analysis sensitivities, reporting limits, analytical results, sampling requirements, surveillance tests, radioactive waste effluent program (RWEP) operating procedures, offsite dose results from liquid effluents, and functional checks and calibrations of equipment associated with the radioactive liquid waste processing syste Selected documents and records listed in Attachment 1 to this report were reviewe The NRC inspectors reviewed current approved revisions of FCS standing orders and procedures governing the release of liquid radioactive wast These liquid effluent release procedures provide for the following:

sampling of radioactive waste; chemical and radionuclides analyses prior to release; calculation of effluent release rates and projected offsite radionuclides concentrations and offsite doses prior to release; verification of effluent radiation monitor setpoints and testing of effluent isolation valves prior to release; recording effluent dilution parameters during releases; and verifying discharge flow rates and effluent volume discharged. Selected documents listed in Attachment 1 to this report were reviewe The NRC inspectors reviewed a representative number of liquid release permits for the period January through December 1988. It was determined that processing, sampling and analysis, and approval and performance of the releases were conducted in accordance with FCS procedures. Quantities of radioactive nuclides released in the liquid effluents were within the limits specified in the RET Offsite doses had been calculated according to the ODCM and were within the TS limits. During the review of the liquid release permits, the NRC inspectors observed that the i

Chemistry / Radiation Protection Supervisor or Plant Chemist no longer was l required to approve and sign the liquid effluent release permit prior to its submittal to the control room and shift supervisor for performance of the discharge of liquid radioactive waste to the river. The only required

'

signature was that of the chemistry technician who performed the chemistry I analyses and prepared the release permit. This appeared to be a reduction i' in station management oversight of the release of radioactive waste

! materials beyond the site boundary. The NRC inspectors discussed this observation with the licensee's representatives during the exit interview on March 3, 1989, expressing the concern that the deletion of the supervisory approval signature on the liquid effluent releases may be a

reduction of safety precautions involving release of radioactive material

~

to the environment. The licensee agreed to evaluate the necessity of supervisory approval of the liquid effluent release permits prior to submittal to the shif t supervisor for initiation of the release The NRC inspectors also observed that liquid effluent releases (88090-88149) had received a final review, but they were signed by an alternate for the Plant Chemist and the remaining liquid effluent releases for 1988 (88150-88201) and all liquid effluent releases performed during January through. February 1989 had not been reviewed and signed by the Plant Chemist at the time of the inspection. This appeared to the NRC inspectors as another example of lack of management oversight in conducting the RWE The NRC inspectors determined that a contract had been awarded to the Duratek Company to process the station's liquid radwaste. The Duratek Enhanced Volume Reduction Processing System replaces the station's radwaste denineralizers and waste evaporator for processing liquid radwast The NRC inspectors reviewed procedures and selected reactor coolant and secondary water chemistry analyses records for the period January through December 198 The records reviewed indicated that all required sampling and analyses were performed at the frequencies required by the TS and the analyses results met TS requirement The NRC inspectors reviewed selected QA audit and surveillance reports of QA activities performed during 1987 and 1988 in the areas of radioactive waste effluent releases. The reports were reviewed for scope and thoroughness of program evaluation and timely followup of identified deficiencies. The NRC inspector determined that QA surveillance had been performed in accordance with FCS procedure The NRC inspectors reviewed the Safety Audit and Review Committee Audit No. 8-88, " Radiological Effluent Program," performed during the period October 31 through November 10, 1988, and found the audit plan to

,

be technically comprehensive. It was noted that 10 Deficiency Reports and 8 Quality Reports were issued as a result of the audit. The NRC inspectors reviewed the licensee's responses and corrective actions to these audit findings and found two Deficiency Reports closed and four Quality Reports closed at the time of the inspection. The remaining audit findings were in the progress of being resolved and had been assigned completion dates prior to July 1,198 No violations or deviations were identifie . Gaseous Waste System (84750, 84524, 84724)

The NRC inspectors reviewed the licensee's gaseous radioactive waste effluent program including: gaseous waste system construction and installation, gaseous radwaste sampling, procedures for gaseous waste and effluent systems, and air cleaning systems to determine agreement with commitments in Chapters 6, 9, and 11 of the USAR and the requirements in Sections 2.9, 3.6, 3.12, and 5.8 of the T _ _ _ _ _ - _ _ - _ _ - _ - _ _

The NRC inspectors reviewed the licensee's' implementation of the RETS and ODCM to ensure agreement with analysis sensitivities, reporting limits, analytical results, sampling requirements, surveillance tests, RWEP operating procedures, offsite dose results from gaseous effluents, and functional checks and calibrations of equipment associated with the radioactive gaseous waste processing syste Selected documents and records listed in Attachment 1 to this report were reviewe The NRC inspectors reviewed current approved revisions of FCS standing orders and procedures governing the release of gaseous radioactive wast These gaseous effluent release procedures provide for: the sampling of gaseous radioactive waste; radionuclides analysis prior to release; calculation of effluent release rate, projected offsite radionuclides concentrations, and offsite doses prior to release; verification of gaseous effluent radiation monitor setpoints and testing of effluent isolation valves prior to release; recording of meteorological conditions during releases; and verifying discharge flow rates and effluent volume discharged. Selected documents and records listed in Attachment 1 to'this report were reviewe The NRC inspectors reviewed selected gaseous waste release data and permits which included plant stack continuous releases and batch releases from waste gas decay tanks and containment for the period January through December 1988. It was determined that the gaseous waste releases were being performed according to FCS procedures and the quantities of gaseous radioactive nuclides released were within the limits specified in the RET Offsite doses had been calculated according to the 00CM and were within the TS limits. The NRC inspectors reviewed the licensee's analyses results to determine compliance with the requirements of TS 2.9.1(2) and 3.12.1(2) and Table 3-12. The NRC inspectors determined that no design changes had been made to the gaseous radwaste management system since the previous NRC inspection in December 198 The NRC inspectors reviewed the instrument operability checks of the hydrogen and oxygen monitors on the gaseous waste system. These monitors are to monitor the in-service gas decay tank during the transfer of waste

gases to the gas decay tank to ensure that the hydrogen and oxygen

'

concentrations are maintained below an explosive mixture. The hydrogen and oxygen monitors have been out-of service since June 10, 1988. Due to this monitor inoperability, the licensee has been required by TS to take grab samples from the in-service gas decay tank during transfer of waste gases and analyze these samples for oxygen and hydrogen concentratio The NRC inspectors reviewed the results of these analyzes and verified that the TS requirements were being me The NRC inspectors reviewed the licensee's procedures, surveillance tests, and selected records and test results for maintenance and testing of air cleaning systems which contain high efficiency particulate air (HEPA)

filters and activated charcoal adsoruers. The NRC inspectors verified that the licensee's procedures and surveillance tests provided for the l _- _ - _ _ _ _ _ - _ _ _ _ _ _ -

required periodic functional checking of ventilation system components, evaluation of HEPA and activated charcoal adsorbers, tracking of system operating hours, and replacement and in place filter testing of filter system The NRC inspectors reviewed selected records and test results for the period January through December 1988 for the control room, containment building, safety injection pump room, spent fuel pool area, and auxiliary Iuilding air cleaning system The in place filter testing and activated charcoal laboratory tests had been performed by approved and Q' audited contractors and all test results were verified to be within TS limits. Selected documents and surveillance tests listed in Attachment 1 to this report were reviewe The NRC inspectors determined that the licensee was using a contractor to perform in place filter testing and a second contractor laboratory to perform charcoal adsorber enalyses on station ventilation systems as required by TS. The licensee had performed a QA program audit on each of the contractors performing the in place filter testing and laboratory analyses on the station ventilation systems and had placed the contractors

.on the FCS routine supplier's lis No violations or deviations were identifie . Reports of Radioactive Effluents (84750)

The NRC inspectors reviewed the licensee's reports concerning radwaste systems and effluent releases for compliance with the requirements of 10 CFR Part 50.36(a)(2) and Section 5.9.4.a of the T The NRC inspectors reviewed the semiannual effluent release reports for the periods July 1 through December 31, 1987; January 1 through June 30, 1988; and July 1 through December 31, 1988. These reports were written in the format described 'in NRC Regulatory Guide 1.21 and contained the

~

information required by T No violations or deviations were identifie . Exit Interview (30703)

The NRC inspectors met with the NRC resident inspectors and the licensee representatives denoted in paragraph 1 at the conclusion of the inspection on March 3, 1989. The NRC inspectors summarized the scope and findings of the inspection and discussed the NRC inspectors' observations. The licensee representatives stated at the exit interview that they would evaluate the NRC inspectors' observations and concerns and take necessary corrective action to implement program improvement l l
