No violations or deviations were identified.
5.
Semi-Annual and Annual Reports (80721, 84723, 84724)
Technical Specifications 6.9.1.6 and 6.9.1.8 require submittal of the Annual Radiological Environmental Report and Semi-annual Effluent Release Reports, respectively.
The inspector reviewed Semi-Annual Radioactivt Effluent Reports for 1985.
No technical discrepancies were noted and the reports were consistent with Regulatory Guide 1.21.
Doses for liquid and gaseous pathways were within applicable Technical Specification limits.
The meteorological data indicates a high data recovery rate for the second, third and fourth quarters.
This was significant improvement over first quarter recovery rates.
The meteorological computer compares data from the primary and secondary sensors to evaluate' operability of individual components as well as eliminate incorrect data.
The inspector toured the meteorological station and reviewed the maintenance logs and channel check records.
The inspector had no further questions.
The inspector reviewed a draft of the 1985 Annual Radiological Environmental Report. The report included all required information and no obvious errors

were noted.
The inspector determined that the program was performed as
required.
No violations or deviations were identified.

Radioactive Gaseous Waste and Gaseous Effluent Treatment Systems (84724)
Technical Specification 3/4.11.2 establishes upper limits for concentrations of radioactive material in gaseous effluents, t
The inspector selectively reviewed release records from January '- March 1935. All releases were within limits.
Technical Specifications 4.6.6.3 and 4.7.2 give surveillance requirements for the Standby Gas Treatment System and Control Room Emergency Filtration System, respectively.
The inspector reviewed Operations and Maintenance records from August 1985 to April 1986.
These records covered blower, isolation and operability tests of both the above systems, 'as well as charcoal absorber analysis and in-place leak testing of component filters. The inspector had no further.
questions
No violations or deviations were identified.
i 7.
Radioactive Liq;id Waste (84723)
Technical Specification 3/4.11.1 establishes upper limits for concentrations of radioactive materials in liquid effluents.
The inspector reviewed selected release ' records to verify conformance with
!
technical specifications.
For a selected release, the inspector performed dose calculations using the current revision of the ODCM for two nuclides
,
and two different organs.
The calculations agreed with the licensee
,
computer generated dose projections.
The inspector discussed operational
'
performance of the liquid radwaste systems.
There have been some routine problems noted, but the processing load due to -leakage had been reduced during the past year. Currently, the.radwaste demineralizers are effective
'
for over a year.
No violations or deviations were identified.
8.
Radioactive Effluent Monitoring Instrumentation (83723, 83724)
i Technical Specification 3/4.3.7.1 requires radioactive liquid-and gaseous
.
effluent monitoring instrumentation channels to be operable with their
alarm /t ip setpoints set in accordance' with. specified limits and give minimue time intervals for channel checks, channel functional tests, and channel calit ation operations.

The inspector observed monthly channel functional tests of the Standby Service Water Radiation Monitors A and B, the Component Cooling Water Radiation Monitor and the Radwaste Effluent Radiation Monitor.
The operability of Control Room readouts for the radioactive effluent monitoring instrumentation were verified by direct observation.
Review of selected records from December 19S? to April 1986 showed that the surveillance program for channel checks, channel functional _ tests and channel calibrations met the technical specification requirements.
For gaseous monitors the alarm / trip setpoints arc set using the most conservative point determined from either the annual calibration or monthly grab sample analysis. For liquid monitor alarm trip setpoint, minimum dilution flow and total tank voiding are assumed to determine conservative setpoints.
No violations or deviations were identified.
