J.J. Kottan,' Acting Chief, Effluents date Radiation Protection Section Inspection Summary:
Inspection on October 18-22, 1982 (Report No. 50-213/82-20)
Areas Inspected:
Routine, unannounced inspection of environmental monitoring program for operations. The areas inspected included: management controls, the licensee's program for quality control of analytical measurements, imple-mentation of the environmental monitoring program - radiological and biological / ecological, and a follow-up on licensee action on previous en-vironmental inspection findings. The inspection involved 32 onsite inspect-or-hours by one regionally-based NRC inspector.
Results: Of the five areas inspected, no items of noncompliance were iden-tified.

Submission of Vendor Audit Responses for 1980.
The inspector reviewed Vendor Audit Responses.
l (Closed) Follow-up Item (231/80-25-02):

3.
Management Controls - Environmental Monitoring a.
Changes l
The inspector reviewed the licensee's organization for the manage-ment of the environmental programs and identified no changes which would result in a decrease in overall effectiveness of management controls.
The inspector had no further questions in this area.

b.
Licensee Audits The inspector reviewed the semi-annual audits of the environmental programs, conducted by the Environmental Review Board from " Summer 1981" through " Summer 1982." The inspector noted that the audits had been conducted in accordance with Procedure CYERB-1, Revision 0,
" Periodic Environmental Audits." The inspector determined that responses to identified deficiencies were issued in a timely manner.
The inspector determined through records review that the primary radiological analytical contractor (Chemical Waste Management o f Massachusetts, Inc., formerly Interex) was audited on June 24, 1382; May 18, 1982; and October 5, 1982. The quality control analytical contractor (Yankee Atomic Environmental Laboratory) was introduced and was audited in 1982.
Satisfactory responses had been received for all audits in the time specified.
No items of noncompliance were identified in this area.
4.
Licensee Program for Quality Control of Analytical Measurements The inspector reviewed the following procedures:
a.
RAB 3-1, Revision 2, October, 1982, Quality Control of TLD Monitor-ing Program; b.
RAB 3-2, Revision 3, October, 1982, Quality Control of Radiological Environmental Monitoring Program; and c.
RAB 3-3, Revision 4, October, 1982, Radiological Analysis Data Checks.
The inspector noted that these procedures contained the assignment of responsibility to manage and conduct the program, type and number of measurements checks, acceptance criteria, and follow-up to correct identified deficiencies.
The inspector reviewed records of the quality control program for 1981 and 1982 and noted that acceptance criteria had been applied to the results.
The inspector also noted that discrepancies were addressed and corrective actions taken as appropriate.
No items of noncompliance were identified.
5.
Implementation of the Environmental Monitoring Program - Radiological a.
Direct Observation The inspector examined selected air sampling, water sampling, and TLD monitoring stations. The inspector determined that the examined stations were located as required by the Environmental Technical Specifications (ETS) and were operating at the time of the
o
.
inspection. The inspector also noted that the air samplers and dry gas flow meters were maintained and calibrated on a routine basis.
b.
Review of Annual Reports The inspector reviewed annual reports for 1980 and 1981 and preliminary radiological program data available from 1982. The inspector determined that the licensee has complied with the ETS in terms of sampling frequencies, sampling locations, measurements, analytical sensitivities, and reporting schedules.
The inspector reviewed corrective actions for the previous in-spection follow-up item (213/80-25-02). The licensee reported Ra-226 activities in well water samples based on the equilibrium of Ra-226 and daughter products which was not an accurate assumption in many cases. The inspector noted that the licensee now reported 81-214 activities in the annual report instead of Ra-226. The analysis of Cs-137 in water, fish, and shellfish was performed using a radiochemical separation method and counting with a low background proportional counter in order to meet the required sensitivity.
This method was unsuitable to distinguish Cs-137 from Cs-134 and was actually a determination of total radioactive cesiua. The inspector noted that minimum detectable levels (MDLs) of Cs-137 for water, bottom sediment / soil, fish / shellfish, and vegetation samples were increased by Amendment No. 32 issued March 15, 1979. Therefore, required MDLs of Cs-137 for all sample media could be met by gamma spectrometry. The licensee discontinued the cesium radiochemical separation method. The inspector verified that required MDLs of Cs-137 were met and determined the corrective actions were adequate.
The inspector noted that unusual levels of Cs-137 and Sr-90 had been reported in goat milk samples. The licensee stated that the anoma-lous Cs-137 and Sr-90 results were due to the feeding habits and anomalous results would be investigated in the future.
c.
Thermoluminescent Dosimeters (TLDs)
The inspector realized that an unresolved item was identified during the previous inspection in this area.
The inspector reviewed the licensee's evaluation of TLD performance and noted that TLD response to energies between 1 MeV and 3 MeV was not determined (213/78-03-10).
The inspector reviewed the corrective actions during this in-spection. The inspector noted that the licensee obtained the energy response data up to 1.25 MeV from the TLD manufacturer and had used these data. The inspector also noted that the licensee calculated the theoretical responses to energies between 1.25 MeV and 3.0 MeV and scheduled a calibration during November 1982 (1.25 Mev). The inspector stated that the corrective actions were adequate.

d.
Meteorological Monitoring The inspector reviewed the instrumentation at the base of the meteorological tower and in the Control Room and determined that they were functioning at the time of inspection. The inspector also reviewed and discussed calibration records for 1981 and 1982 and the maintenance program.
The inspector determined that the instrumentation was routinely calibrated and weekly system checks were performed. The inspector had no further questions in this area.
No items of noncompliance were identified in this area.
6.
Implementation of the Environmental Monitoring Program - Biological /
Ecological a.
Review of Annual Reports The inspector reviewed the nonradiological environmental operating reports for 1980 and 1981, and determined that the required sampling, analyses, and reporting had been performed. Areas re-viewed included the water quality monitoring parameters (e.g., pH and temperature), fish impingement monitoring and shad monitoring studies. No items of noncompliance were identified.
b.
Review of Non-routine Reports The inspector reviewed the following non-routine environmental reports concerning plant effluent water quality.
Report Date Report Number Subject January 13, 1981 EST-NR/81-01 Increased impingement rate of spottail shiners August 25, 1981 EST-NR/81-02 Release of radioactive gas due to boro, dilution system December 8, 1981 EST-NR/81-03 Release of sodium hypochlorite and fish kill The inspector reviewed the licensee's ecological study for EST-NR/81-01 and corrective actions for EST-NR/81-02 and EST-NR/81-03.
The inspector had no further questions regarding the above ecologi-cal study and corrective actions at this time.
