Dear Ms. Ade sam:
In the Matter of
)
Docket Nos. 50-327 Tennessee Valley Authority
)
50-328 We request an exemption to the reporting mquirements of 10 CFR 50.73(a)(2)(viii)A, which became effective January 1, 1984, regarding airborne radioactive releases for Sequoyah Nuclear Plant (SQN). This plant has implemented the Nuclear Regulatory Commission (NRC) -dose methodology guidelines (Regulatory Guide 1.109 - October 1977-R1, NUREG-0472) in the Offsite Dose Calculation Manual (ODCM) to demonstrate compliance with 10 CFR 50, Appendix I criterion, '"As Low As Is Reasonably Achievable (ALARA) for Radioactive Material in Light Water Cooled Nuclear Power Reactor Effluents."
The enclosed table I outlines the maximum permissible boundary concentration limits of Appendix B of 10 CFR 20,10 CFR 50.73 reporting values, and SQN site boundary concentration limits derived from ODCM methodology to meet 10 CFR 50, Appendix I and Technical Specification (TS) 3 11.2.1 dose criteria for SQN.
Site boundary noble gas concentrations, approximately one-third of the derived TS allowable normal-operating limits, would have to be reported as Licensee Event Reports unless an exemption to the 10 CFR 50.73 reporting mquirements is
. granted.
Therefore, TVA requests an exemption to the reporting mquirements of 10 CFR 50 73(a)(2)(viii) A to resolve the inconsistency between the reporting mquire-ments of 10 CFR 50.73 and the TS for SQN. TVA proposes to report those conditions for which releases of radioactive materials in gaseous effluents exceed the limits of the TS, provided as Appendix A to the operating license for
- each unit.
