4..
Unresolved Items Unresolved items were not identified during this inspection.
5.
-Status of Radiological Environmental Monitoring Program a.
License Condition 39 of license No. SNM-1107 requires implementation of a radiological monitoring program and specifies the analyses required, e.g., soil, sediment, vegetation, ground and surface water, fallout, fish and direct radiation. The inspector reviewed sample collection records and analytical results to verify the implementation of the program. Where analytical results had not been completed by the licensee's contract laboratory, the inspector reviewed the sample collection and shipp.ing logs to verify that the samples had been collected. The inspector also discussed the schedule for collection of annual' fish and sediment samples with cognizant licensee representatives. The inspector had no questions concerning the implementation of ti,e environmental monitoring program during the period August 1982 - July 1983.
2 b.
The inspector accompanied a licensee representative on a tour of various sampling stations specified in License Condit. ion 39. The inspector verified that the air sampling stations were operating.
In Region II Report 70-1151/82-19, aninspectorfollowupitem(82-19-01) was identified concerning the condition of the air sampling station shelters, and the protection of the samplers from rain or other weather conditions. The inspector observed that new sampling station shelters had been_ installed which provide protection of the sample media from the weather. The inspector had no further questions and informed licensee management that followup item 82-19-01 was closed.
6.
Laboratory Quality Control Program a.
The inspector reviewed the QC program for laboratory measurements and contractor work in the environmental monitoring area. Other pertinent subjects, e.g., management control and procedures, are discussed in other paragraphs, b.
Inspector followup item 82-18-01 dealt with the need for audits or other checks of the contract laboratory performance. A licensee representative stated that the contractor submits the laboratory quality control data with the periodic reports of the sampling results. These data will be reviewed when received. Additionally, the licensee submitted twenty samples, which included spiked samples, duplicate samples and blanks, to the contract laboratory. Based on the reported results of these samples, the licensee will determine whether to conduct a formal audit or establish other methods of checking the contractor's performance.
The inspector informed licensee management that item 82-18-01 would remain open pending completion of the review of the contractor's performance.
c.
Inspector followup item 82-18-02 dealt with the need for documenting and investigating deficiencies identified in the programs. The inspector reviewed the monthly environmental monitoring reports and Regulatory Compliance Committee reports and determined that both reports provide a mechanism for identifying and documenting corrective actions of deficiencies. The inspector also determined that the laboratory procedures have specific action levels on sample results. The inspector informed licensee management that item 82-18-02 was closed.
7.
Management Controls a.
The inspector reviewed the management responsibilities and controls as they relate to the environmental monitoring and laboratory QC program.
Plant procedure CPC-33 assigns overall responsibility for these programs to the Manager, Regulatory Compliance. Responsibility for the operation and maintenance of the laboratory is further delegated to the Manager, Health Physics Operations.
Radiological and Environmental Engineering is assigned responsibility for the environmental monitoring program.
a 3
b.
A Senior Radiological and Environmental Engineer is assigned responsibility for the environmental monitoring program. This responsibility includes review of the contract laboratory work and coordination with appropriate state agencies.
c.
Results of the program, including identified problems and/or deficiencies are reported to management by means of the Monthly Summary Effluent and Environmental Monitoring Report. Additionally, the Regulatory Compliance Committee reviews effluent releases and environmental monitoring data as part of the plant ALARA program.
8.
Review of Stack Sampling Assemblies Inspector followup item 82-18-05 dealt with the evaluation of stack sampler flow measurement compensation. Such compensation is necessary as the sampler and rotameter operate under vacuum conditions and the rotameters are calibrated for atmospheric pressure. The licensee conducted an evaluation of the flow rates at operating conditions vice ambient conditions and developed a flow rate correction factor for the rotameters.
Separate correction factors were included in the calculations for inplant and stack samplers. The factors were incorporated in procedure HP-06-002, Rev. 3, and the Effluent Air Sampling Report computer program. The inspector had no further questions and informed licensee management that item 82-18-05 was closed.
9.
Review of Procedures and Records a.
The inspector reviewed the following procedures and records related to the radiological environmental monitoring program and the laboratory QC program.

In Region 11 inspection report 70-1151/82-18, an inspector followup item (82-18-03) was identified concerning the lack of an operating procedure for the Tennelec LB5100 Alpha-Beta counters. The inspector reviewed procedure HP-01-024, Rev. O, and the referenced Tennelec technical manual, and discussed the operation with the cognizant supervisor. The inspector had no further questions and informed licensee management that item 82-18-03 was closed.
c.
Inspector followup item 82-18-04 dealt with the evaluation of counting losses due to self-absorption in sampling media and the resulting correction factors. The inspector discussed the evaluation with the cognizant individual, who explained that differences in the self-absorption factor had been identified between different types of sampling media but the final results of the evaluation were not complete. The inspector informed licensee management that item 82-18-04 would remain open pending completion of the evaluation.
10.
Confirmatory Measurements a.
During the inspection covered by Region II report 70-1151/82-18, samples were collected for analysis by the NRC contract laboratory and the licensee's laboratory. Due to handling errors in the preparation of the licensee's laboratory sample, the results of the two labora-tories could not be adequately evaluated. The inspector informed licensee management that followup item 82-18-06 was closed for record purposes.
.b._
The inspector selected two stack particulate filters and a liquid effluent sample. The filters and the liquid sample were analyzed by the licensee in the health physics laboratory for gross alpha radioactivity. The samples were then analyzed in the Region II laboratory. The results of the two laboratories and a comparison of the results are shown in Table 1.
c.
After the initial NRC analysis of filter No.15 showed only "possible agreement", the filter was counted several times over an eight day period. The analysis showed that a short-lived nuclide was present on the filter, making a comparison of the licensee results and NRC results difficult.
However, based on acceptable results (" agreement")
for filter No. 24 and the water sample, the inspector had no further questions concerning the licensee's measurement program.
