The inspector also interviewed other licensee personnel.
2.0 Mana ement Controls.
The inspector reviewed the licensee's management controls for the radioactive liquid and gaseous effluent control programs, including organization, program audits, and semiannual effluent reports.
The inspector reviewed the organization for administration of the radioactive effluent monitoring programs;
"Nuclear Generation Organization Chart, Nine Mile Point Nuclear Site, July 31, 1988".
Radwaste operations, chemistry, radiation protection, and instrument and controls ( 1&C) have responsibilities in. the radioactive effluent programs.
Electronic calibration of the effluent monitors is handled by the I&C Department.
Radiological calibration of the effluent monitors is handled by the Radiation Protection Departments Preparation of the radioisotope standards for the calibration, effluent sample analyses, and semiannual effluent reports are performed by the Chemistry and Radiochemistry Department.

'QA Audit Report 087028-RG/IN SRAB Audit-0; Chemistry and Radiation Management November 30-December 11, 1987 SRAB Audit-K; Offsite Dose Calculation Manuals October 13-15, 1987
.
'QA Audit Report 088006-RG/IN SRAB Audit L; Radwaste Process Control Program Units 1 and
July 1988 The inspector noted that the above referenced audits were very thorough.
The inspector also noted that the audit scope was excellent.
The Audit-K, Offsite Dose Calculation Manuals (ODCM), covered the following areas in detail;
'et point determination for gaseous and liquid effluents
~ dose determination,
~ accumulating dose calculation, and
~ liquid effluent concentration calculation The inspector noted that SRAB Audit L contained previous audit followup items in the effluent area.
These items were reviewed and closed by SRAB Audit members during SRAB Audit - L.
The inspector also noted that the licensee has a tracking system for identified followup items.
2.3 Review of Semiannual Effluent Re orts k
The inspector reviewed the Unit 1 semiannual effluent reports for 1987 and the Unit 2 effluent reports for 1987 and 1988.
The Unit 2 semiannual reports provided total released radioactivity for liquid and gaseous effluents including radiation dose to the public.
The inspector noted that Unit 1 has not discharged any liquid radwaste since June 1986.
Therefore, the radiation dose to the public was calculated using gaseous effluent data.
Through review of these reports, the inspector determined that, the licensee met the Technical Specification requirements.
No problems were identified in the area of the management control.0 Radioactive Li uid Effluents 3.1 Unit

3.2.3 Review of Li uid Effluent Release Permits The licensee's program for liquid effluent release was reviewed against criteria contained in:
~Technical Specification 3/4. 11. 1, "Liquid Effluents"
~Offsite Dose Calculation Manual
~Regulatory Guide 1.21; "Measuring, Evaluating, an'd Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials in Liquid and Gaseous Effluents from Light-Water-Cooled Nuclear Power Plants".

~ N2-CSP-5V; Revision 1, July 14, 1987 "Circulating and Service Water Chemical Surveillance at Unit 2"
~Associated chemistry procedures.
The inspector reviewed selected liquid release permits to determine compliance with the above requirements.
During the review of the release permits, the inspector noted that the liquid effluent monitor was out of service.
During the period the monitor was.out of service, the licensee took two indepen-

~ g
dent grab samples and analyzed those samples as required by the Technical Specifications.
The licensee declared the monitor was inoperable due to the increase of background counts during effluent releases.
The monitor normally read about 300 cpm (counts per minute) background count rate.
Due to the con-figuration of the monitor chamber, some particulates were trapped in the chamber, resulting in background counts of about 900 cpm which was the near alarm setpoint.
When this occurred, the licensee stopped discharge.
The inspector reviewed release permits with monitoring data and grab sample analytical data and found that the background count rates were increasing due to the trapped particulates not due to high activity in the liquid effluent tank.
Currently, the licensee is modifying the monitor chamber to avoid trapping of particulates.
Based on the above review, the inspector determined that the licensee has an effective radioactive liquid effluent control program for Unit 2.
No problems were identified.

"Gaseous Radioactive Waste Chemistry Surveillance at Unit 2" The licensee uses the Gaseous Effluent Monitoring Systems (GEMS) to monitor radioactive gaseous effluents at the main stack and the radwaste/reactor building ventilation system.
The inspector reviewed calibration data collected on July 8, 1988 for the main stack and collected on July 6, 1988 for the radwaste/reactor building ventilation system.
All results were acceptable.
Several other tests are being performed as part of the calibration.
If these test results are acceptable, the GEMS will be designated as operable.
