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

a. Inspection Scope This area was inspected to: (1) ensure that the gaseous and liquid effluent processing systems are maintained so that radiological discharges are properly mitigated, monitored, and evaluated with respect to public exposure; (2) ensure that abnormal radioactive gaseous or liquid discharges and conditions, when effluent radiation monitors are out-of-service, are controlled in accordance with the applicable regulatory requirements and licensee procedures; (3) verify that the licensee=s quality control program ensures that the radioactive effluent sampling and analysis requirements are satisfied so that discharges of radioactive materials are adequately quantified and evaluated; and (4) verify the adequacy of public dose projections resulting from radioactive effluent discharges. The team used the requirements in 10 CFR Part 20; 10 CFR Part 50, Appendices A and I; 40 CFR Part 190; the Offsite Dose Calculation Manual, and licensee procedures required by the technical specifications as criteria for determining compliance. The team conducted in-office inspection and reviewed:

  • The implementation of the radiological effluent controls program requirements as described in radiological effluent technical specifications;
  • Effluent monitoring instrumentation documentation to ensure adequate methods and monitoring of effluents;
  • The program for identifying, assessing, and controlling contaminated spills and leaks;

-4- Enclosure

  • The annual effluent release reports and the correlation to the environmental monitoring results; and
  • The results from quality assurance audits.

The team conducted an onsite inspection, which included interviewing cognizant licensee personnel, performing walkdowns of facilities and equipment, and observing licensee activities to review:

  • The gaseous and liquid discharge system configuration;
  • Selected point of discharge effluent radiation monitoring systems and flow measurement devices;
  • The observation of selected portions of the routine processing and discharge of radioactive gaseous and liquid effluent (sample collection and analysis) including a selection of radioactive gaseous and liquid waste effluent discharge permits;

  • Surveillance test results on non-safety related ventilation and gaseous discharge systems (HEPA and charcoal filtration) including the methodology to determine the stack and vent flow rates;
  • The identification of non-radioactive systems that have become contaminated;
  • Effluent monitoring instrument (installed and counting room) maintenance, quality control, and calibration;
  • The methods used to determine the isotopes in the plant source term, meteorological dispersion and deposition factors, and hydrogeologic characteristics used in the Offsite Dose Calculation Manual and effluent dose calculations including a selection of monthly, quarterly, and annual dose calculations;
  • The land-use census;
  • The implementation of the voluntary Nuclear Energy Institute/Industry Ground Water Protection Initiative;
  • Records of abnormal gaseous or liquid discharges including the evaluation and analysis of events involving spills or discharges, dose assessments to members of the public, required (or voluntary) offsite notifications, and assessments and reporting of abnormal discharges in the annual radiological effluent release report;

Inspection Scope This area was inspected to verify that the licensee=s radioactive material processing and transportation program complies with the requirements of 10 CFR Parts 20, 61, and 71 and Department of Transportation regulations contained in 49 CFR Parts 171-180. The team interviewed licensee personnel and reviewed:

  • The radioactive waste system description, recent radiological effluent release reports, and the scope of the licensee=s audit program;
  • Liquid and solid radioactive waste processing systems configurations, the status and control of any radioactive waste process equipment that is not-6- Enclosure

operational or is abandoned in place, changes made to the radioactive waste processing systems since the last inspection, and current processes for transferring radioactive waste resin and sludge discharges;

2PS3 Radiological Environmental Monitoring Program And Radioactive Material Control Program (71122.03)

a. Inspection Scope This area was inspected to ensure that the radiological environmental monitoring program verifies the impact of radioactive effluent releases to the environment and sufficiently validates the integrity of the radioactive gaseous and liquid effluent release program; and that the licensees surveys and controls are adequate to prevent the inadvertent release of licensed materials into the public domain. The team used the requirements in 10 CFR Part 20, Appendix I of 10 CFR Part 50, the Offsite Dose Calculation Manual, and the licensees procedures required by technical specifications as criteria for determining compliance. The team interviewed licensee personnel and reviewed:

  • Annual environmental monitoring reports and licensee event reports;
  • Selected air sampling and thermoluminescence dosimeter monitoring stations;
  • Collection and preparation of environmental samples;
  • Operability, calibration, and maintenance of meteorological instruments;

-7- Enclosure
