2PS1 Radioactive Gaseous and Liquid Effluent Treatment and Monitoring Systems (71122.01)

a. Inspection Scope

This area was inspected to ensure that the gaseous and liquid effluent processing systems were maintained so that radiological releases were properly mitigated, monitored, and evaluated with respect to public exposure. The team conducted an in-office review of the licensees annual reports, self-assessments, and corrective action documents. On site, the team examined procedures and representative records; walked down the major components of the radwaste, fuel handling area, containment, and turbine building gaseous and the liquid effluent release systems; and interviewed cognizant personnel. The team observed sample preparation, collection, and analysis of gaseous effluent from the fuel handling area exhaust and the offgas post-treatment monitor for compliance with procedural and regulatory requirements. Additionally, the following items were reviewed and compared with regulatory requirements and commitments in the Updated Final Safety Analysis Report:

  • Unplanned, monitored releases reported in the 2001 Radiological Effluent Release Report
  • Effluent radiological occurrence performance indicator incidents (no occurrences during the inspection period)
  • Effluent radiation monitor alarm setpoint values and calculation methodology
  • Selected radioactive liquid waste and gaseous release permits and associated projected doses to members of the public
  • Compensatory sampling and radiological analyses conducted for unmonitored releases and when effluent monitors were declared out-of-service
  • Monthly, quarterly, and annual dose calculations
  • Air cleaning system surveillance test results for the Control Room Ventilation and Fuel Handling Building Systems.
