. Washington Nuclear Project-2 NRC Inspection Report 50-397/98-17 This routine, announced inspection reviewed the implementation of the radiological environmental monitoring and the meteorological monitoring programs.
Training and qualifications, quality assurance oversight, facilities and equipment, and annual reports were also reviewed.
PI u
Overall, good radiological and meteorological monitoring programs were implemented.
Replacement of all environmental air sampler units in 1997 reduced equipment malfunctions from 19 in 1996 to 4 in 1997. The annual land use censuses were properly conducted.
Sample collection logs, shipment and release forms, and sample analyses reports were meticulously maintained at a high level of quality. Meteorological data recovery was greater than 92 percent from 1995 through 1997.
Comprehensive radiological 'environmental operating reports were submitted in a timely manner.
These reports discussed such anomalies as detectable levels of cesium-137 and cobalt-60 found in river sediment and soil samples which were attributed to releases from the Department of Energy during the operation of the old Hanford Reservation reactors.
The licensee identified that the procedures used to calibrate wind speed and delta temperature instrument loops allowed for tolerances outside the limits specified in the Final Safety Analysis Report from 1983 through 1996. A review of calibration records indicated that the actual tolerances of meteorological instruments from 1995 through 1997 were within the Final Safety Analysis Report limits. Inadequate procedural reviews coupled with maintenance personnel performing the calibrations not being familiar with the requirements were identified as the primary contributors for this long-term procedural erro R1 Radiological Protection and Chemistry Controls R1.1 Radiol i al Environmen al Monitorin Pro r m a.
In c ion Sco e 84750 The radiological environmental monitoring program was reviewed to determine compliance with the requirements in the Technical Specifications and Offsite Dose Calculation Manual. Selected environmental media sampling stations were inspected.
b.
Observa i ns n
Findin s The organizational structure of the radiological environmental program remained unchanged since the previous inspection conducted in July 1995.
Personnel from the chemistry department's environmental and analytical section were responsible for the collection, shipment, and documentation of radiological environmental samples.
Analyses of environmental samples were conducted by an offsite contract laboratory.
The inspector accompanied and observed an environmental scientist collect and prepare for shipment air particulate, charcoal cartridge, and water samples.
These activities were all conducted in accordance with approved procedures.
A review of the sample collection logs, sample shipment and release forms, and sample analysis reports revealed that these documents were meticulously maintained and demonstrated a high level of quality.
The inspector determined that the collection, processing, and analyses of the radiological environmental samples were performed in accordance with the Offsite Dose Calculation Manual requirements.
The 1995, 1996, and 1997 annual land use censuses were properly performed, and the land use census results were documented, as required, in the appropriate annual radiological environmental operating reports.
Comprehensive radiological environmental operating reports were submitted in a timely manner.

Ins ec ion co e 84750 The meteorological monitoring program was reviewed to determine agreement with the recommendations in NRC Regulatory Guide 1.23. The inspector reviewed data collection and data displays at station facilities.
Observa i n an Findin s The inspector noted that the meteorological tower's primary and secondary instrumentation and configuration agreed with the guidance in Regulatory Guide 1.23.
The primary tower provided for meteorological instrument redundancy at the 33-and 245-foot levels.
The inspector was informed that the primary tower currently utilizes only one power supply; however, the backup tower utilizes an uninterruptible power supply with two separate sources of power.
The inspector verified that appropriate meteorological data was transmitted and displayed in the station's emergency facilities, including the control room, technical support center, and the emergency operations facility. The system engineer stated that the meteorological data is placed in the site-wide computer system so that all computers connected to this system have access to the data.
The meteorological data recovery rates during 1995, 1996, and 1997 were greater than 90 percent.
Specifically, the data recovery rate for 1995 was 93.9 percent, for 1996 was 97.3 percent, and for 1997 was 92.2 percent.
c.
@~on lumin Overall a good meteorological monitoring program was implemented.
The performance of the meteorological monitoring program agreed with the guidance contained in Regulatory Guide 1.23. Meteorological data recovery was greater than 92 percent from 1995 through 1997.
R2 Status of Radiological Protection and Chemistry Facilities and Equipment R2.1 nvironmen al Monitorin E ui m nt Ins e ion co 84750 Selected environmental sampling stations were inspected to verify that the stations were properly maintained and that all sampling equipment was operable and properly calibrated.
The environmental laboratory located at the Plant Support Facility was
-5-inspected to verify sufficient supplies, equipment, and spare calibrated air samplers were available to perform the licensee's environmental sampling program.
The licensee's maintenance and calibration program for the air sampling equipment was reviewed.
rv i n and Fi in The inspector toured and inspected selected environmental media sampling locations for airborne, water, and thermoluminescent dosimeters.
The inspector verified that the locations of the environmental media sampling stations met the requirements specified in the Offsite Dose Calculation Manual.
Allair samplers in the field were verified operational and properly calibrated.
Proper maintenance and calibration records were maintained for each environmental air sampler.
The inspector noted that between December 1996 through September 1997 all air sampler units were replaced due to a high occurrence of malfunctions.
Through review of air sample deviations listed in the radiological environmental operating reports, the inspector noted. that the number of air sample malfunctions was reduced from 19 in 1996 to 4 in 1997. This indicated that the replacement of air samplers resulted in effectively reducing the number of missed air samples caused by equipment malfunctions.
The environmental laboratory was stocked with the necessary equipment and sufficient supplies to perform the required sampling activities.
c.
~Cn lumin Sufficient supplies and environmental sampling equipment were available and properly maintained.
Replacement of all environmental air sampler units in 1997 reduced the number of equipment malfunctions from 19 in 1996 to 4 in 1997.

4 50 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 Final Safety Analysis Report and the guidance contained in Regulatory Guide 1.23.
Observa ions and Fin in Through review of selected calibration records for the meteorological instrumentation, the inspector noted no occurrences were instrument calibration tolerances exceeded the Final Safety Analysis Report limits. All meteorological instrument calibrations were performed at the required frequenc The inspector reviewed Performance Evaluation Request 297-0241 entitled, "METTower loop inaccuracies in the calculations exceed the values published in the FSAR." This Performance Evaluation Request indicated that from 1983 through 1996 the procedure used to calibrate the wind speed and wind direction instruments, and from 1987 through 1996, the procedure used to calibrate the delta temperature instruments, allowed calibration tolerances outside the Final Safety Analysis Report limits. This error was discovered during a calculation review by system engineers on March 3, 1997. As a result of this review, the calibration procedures were corrected to reflect the Final Safety Analysis Report calibration tolerance requirements on April 15, 1997. A system engineer previously responsible for the meteorological tower stated that inadequate procedural reviews and maintenance personnel performing the calibrations, who were not familiar with the requirements, were the primary contributors for this procedural inconsistency being present for such a long duration.
The chemistry manager stated that the radiological environmental program implementing procedures were currently undergoing a thorough review to identify any inconsistencies and were being changed from Environmental Analytical Laboratory procedures to Chemistry Instruction procedures.
The licensee contracted an outside consultant to evaluate the location of the backup meteorological tower. The consultant indicated that the backup tower was too close to the plant support facility and did not provide representative sampling of the environmental conditions.
In discussions with a system engineer, the inspector was told that the backup tower was originally used as a radio tower, and later meteorological instrumentation was added to the tower to increase the meteorological data recovery rates along with providing an alternate site. The system engineer stated that no formal evaluation had been conducted by the licensee to determine ifthe backup tower meteorological data differed from the data acquired by the primary tower. The chemistry manager stated that the station is currently evaluating suitable alternative sites for backup meteorological instrumentation.
