Selected environmental media sampling stations were inspecte b. Observations and Findinos The inspector accompanied and observed an environmental technician collect vegetation ,
samples. Good sampling techniques were observed. The inspector also observed an !
environmental technician prepare selected environmental samples for analysis and !
perform radiochemistry analyses in the environmental laborator l The collection, processing, and analyses of the radiological environmental samples were performed in accordance with Technical Requirements Manual and Offsite Dose Calculation Manual requirements. The inspector verified that the environmental sample ;
locations were as described in the Technical Requirements Manual and the Offsite Dose Calculation Manual. The 1995,1996, and 1997 annua l land use censuses were properly performed, and the land use census results were documented, as required, in the appropriate annual radiological environmental operating reports. Based on the results of l the annualland use censuses, appropriate changes were made to several environmental sample locations. Environmental samples from all four Entergy Operations nuclear power stations were analyzed by the Entergy Operations corporate environmental laboratory located at the River Bend Statio The radiological environmental monitoring program was implemented in accordance with l the requirements in the Technical Requirements Manual and the Offsite Dose Calculation Manual. Summaries of the 1995,1996, and 1997 environmental sample i analyses results showed that all sample analyses indicated no observed radiological impacts on the environment that could be attributed to station operation. An assessment of the preoperational and operational environmental data showed no changes to the environmental radiation levels due to station operations.

calibrated. The Entergy Operations corporate erivironmentallaboratory facility located on site was inspected to verify that sufficient supplies, equipment, analytical instrumentation, and spare calibrated air samplers were available to perform the licensee's radiological environmental sampling program. The licensee's maintenance and calibration program for the air sampling equlprent was reviewe Observations and Findinas The inspector toured and inspected the following types of sampling sites: air, broadleaf vegetation, thermoluminescent dosimeter, groundwater, surface water, and shoreline sediment. The inspector verified that the locations of the environmental media sampling stations met the requiremen'.s specified in the Technical Requirements Manual and Offsite Dose Calculation Manua The inspector verified that all air samplers in the field were operational and properly calibrated. A timing device was used with each air sampler to monitor its time of operation and to cccount for any power outages during the sampling period. Radiation j controls department technicians were responsible for the maintenance and calibration of the air samplers. The inspector verified that the air samplers were properly maintained I and calibrated semiannually. Proper maintenance and calibration records were maintained for each environmental air sampler. A sufficient supply of calibrated air samplers was maintaine !
All environmental samples were analyzed in the Entergy Operations corporate l environmental laboratory located on site. The inspector verified that the analytical instrumentation was properly calibrated and that an excellent quality control program was implemented. The corporate environmentallaboratory participated in an interlaboratory comparison program as required by the Technical Requirements Manual. The analytical results from the interlaboratory comparison program were reported in the annual radiological environmental operating reports. The 1995,1996, and 1997 analytical
, performance results were within three standard deviations of the known certified results which documented an excellent performanc The inspector inspected the corporate enWronmental laboratory where environmental i sampling equipment was stored, and environmental samples were prepared for analyses.

The meteorological tower instrumentation was inspected. Instrument calibration procedures and records were reviewed to ensure that the meteorological instrumentation was operable and properly calibrated and maintained in accordance with the Technical Requirements Manual and the guidance in Regulatory Guide 1.2 Observations and Findings The inspector toured the meteorological tower with instrument and controls personnel responsible for maintaining and calibrating the meteorological tower instrumentation and the senior environmental specialist responsible for monitoring the meteorological ;
instrumentation reliability and performance. The meteorological tower was equipped with primary and secondary instrumentation for wind speed, wind direction, and temperature measurement at the 30- and 150-foot levels. Daily channel checks were performed by the operations department personnel, and semiannual calibrations of the meteorological I sensing and recording instrumentation were performed by the instrument and controls department personnel. The meteorological instrumentation was operable and property calibrated and maintained. Two major modifications were made to the back-up analog and digital meteorological data recording systems since the previous NRC inspection conducted in July 1996. Six analog chart recorders used for recording analog traces for both the primary and secondary meteorological parameters were replaced with two l digital multiparameter chart recorders. One chart recorder recorded the primary, and the other recorded the secondary wind speed, wind direction, and temperature data. The AMI-80 data acquisition computer system, which serves as the back-up digital data recording system to the digital radiation monitoring system, was upgraded. The two modifications improved the station's ability to accurately record meteorological data using i three independent system The reviewed maintenance and calibration records documented that the meteorological monitoring instruments, including sensing and data recording equipment, were properly tested, calibrated, and maintaine _ - . - _ - _ _ _ _ _ _ . _ _ _ _ _ - _ . . - _ _ _ _ _ - _ _ _ _ _ - _ _ _ _ _ - _ _ _ _ _ - _ _ _ _ __- _ - _ _ - -
