Dunng the inspection, the Arkansas Nuclear one Units 1 and 2 were at power operations. No operational events occurred that affected the results of the inspectio IV. Plant Supped R1 Radiologloal Protection and Chemistry Conwols ,

R Radioloaical Environmentaljionitorina Proaram (84750) Insoection Scope The inspector reviewed the radiological environmental monitoring program to determine compliance with the requirements in Unit i Technical Specification 4.30.1, Unit 2 Technical Specification 3/4.12, and Offsite Dose Calculation Manual Table 4 Qbiefyations and Findin95 Overall, the inspector found that the collection, processing, and analyses of radiological environmental media samples were conducted in accordance with Technical Specifications, station procedures, and the Offsite Dose Calculation Manual. Licensee staffing was adequate and management controls were appropriate. Environmental samples were analyzed by the River Bend Station Environmental Laboratory. Good results were obtained from the laboratory intercomparison program. The land use census was performed as required. The annual radiological environmental operating reports were wntten and submitted to the NRC as require CQDG141iQua A good radiological environmental monitoring program was implemented in accordance with Technical Specification requirement R1.2 Meteomlgaical Monit0DD2 Proaram (84750)

a la5Dfstion Scope The inspector reviewed the meteorological monitoring program to determine compliance with Unit 2 Technical Specification 3.3.3.4, the commitments in the Updated Safety Analysis Report, and agreemen' with the recommendations in NRC Regulatory Guide 1.23. Also, the inspector reviewed data collection and review procedures and discussed the data results with licensee personne b, Observations and Findinat The meteorological tower instrumentation and tower configuration agreed with the guidance in Regulatory Guide 1.23. Good backup methods of obtaining data from the meteorological tower were in place. Backup power was provided by an uninterruptible

-4-power supply (battery) and a propane electrical generator, No redundancy was provided for tower meteorological monitoring instrumentation. The inspector noted that there was no regulatory requirement for maintaining redundant monitoring instrumentatio Meteorological data was available in both units' control rooms and the emergency response facilities via the safety parameters display syste Records reviewed indicated a greater than 99 percent data recovery rate for 1995 and 1996. However, the inspector found that the meteorological data validation process was weak. Data from the meteorological tower was collected without validation as to whether at was good or bad. For example, when the meteorological tower was being calibrated, the data during that time frame was not noted as invalid or inaccurate. That was because the data logging components of the meteorological tower continue to log data during calibration; however, the tower was not in its normal configuration; hence, the data would be inaccurate. The same situation existed when an instrument which was reading erratically. There was no communication link to the person who compiled the meteorological data to exclude certain dats because of it being inaccurate. The licensee acknowledged the inspector's comment and initiated methods for notifying the staff responsible for maintaining the meteorological data when meteorological tower parameters were inaccurat Tino inspector verified that the data recovery rate for 1997 was greater than 90 percen Specifically, the data recovery rate as of the date of this inspection was approximately 96 percent for 1997, Concksloan A good meteorological monitoring program was implemented The performance of the meteorological monitoring program satisfied the commitments of the Update Final Safety Analysis Report and agreed with the guidance contained in Regulatory Guide 1.23. A process had not been established for excluding inaccurate meterological monitoring data from the performance report R2 Status of Radiological Protection and Chemistry Facilities and Equipment R2.1 Environmental MoniquDg Eauioment and Facilities (84750)

sarnpling techniques were observed. All samplo analyses for the radiological environmental monitoring program were performed at another Entergy site (River Bend Station Environmental Laboratory). The chemistry technicians were also responsible for the calibration of the air samplers. New digital volume totalizers had been installed at the environmental air sampling stations and were working properly. All equipment used in the collection of environmental samples was operable and calibrate The inspector obseived that the location of the licensee's environmental air sampling stations were as required by Technical Specifications. The inspector toured the environmental media sample storage and preparation facilities. These facilities were stocked with the necessary equipment and supplies to perform the required sampling activities and sample thipment preparatio c C9 aclu 11Qua The licensee maintained sufficient supplies and spare environmental sampling equipment to perform the activities described in Technical Specifications and Offsite Dose Calculation Manual. Environmental monitoring stations were properly maintained with operable and calibrated equipmen R2.2 Mitteoroloaical MonitQdDa Eauioment (8475Q) [aspection Scopa The inspector observed the meteorological monitoring instrumentation at the meteorological tower and reviewed associated calibration records to ensure that the meteorological instrumentation on the towers was operable, calibrated, and maintained in +

accordance with wntien procedures, the guidance in Regulatory Guide 1.23, and Updated Safety Analysis Repor b Observations and Findinas The inspector toured the meteorological tower with a instrument and controls technician responsible for performing periodic calibrations of the monitoring equipment. The licensee maintained an excellent meteorological tower with monitoring instrumentation at the 10 and 57 meter levels. The instrumentation at these levels included wind speed, wind direction, and temperature sensing instrumentation. Instrumentation, including recording and transmitting equipment, was noted to be in good operating conditio The inspector reviewed meteorological instrumentation calibration procedures and associated records. The inspector determined that the meteorological sensing and recording equipment was calibrated semiannually by the licensee's instrument and controls department. The calibrations were conducted in accordance with approved procedures. All records reviewed hdicated that the meteorological monitoring instruments were being properly maintained, tested, and calibrated at required frequencies.
