SAFETY EVALUATION BY THE OFFICE OF SPECIAL PROJECTS SUPPORTING AMENDMENT NO.143 TO FACILITY OPERATING LICENSE NO. DPR-33 AMENDMENT NO.139 TO FACILI,TY OPERATING LICENSE N0. DPR-52 AMENDMENT N0. 114 TO FACILITY OPERATING LICENSE NO. DPR-68 TENNESSEE VALLEY AUTHORITY BROWNS FERRY NUCLEAR PLANT, UNITS 1, 2 AND 3 DOCKETS NOS. 50-259, 50-260 AND 50-296
1.0 INTRODUCTION
The proposed amendment would revise the limiting conditions for operation for the Standby Gas Treatment System, the Control Room Ventilation System and the Primary Containment Purge Systen.
In each case, the proposed change would replace ANSI N510-1975, which is currently referenced in the Technical Specifications for the radioactive methyl iodine removal effectiveness test of charcoal filter samples, with ASTM D3803. ASTM D3803 is referred to in ANSI N510-1980 as the proper test to use for measurir 4thyl iodine removal effectiveness.
2.0 EVALUATION Regulatory Guide 1.52, "Design, Testing, and Maintenance Criteria for Post Accident Engineered-Safety-Fer.ture Atmosphere Cleanup System Air Filtration and Adsorption Units of Light-Water-Cooled Nuclear Power Plants " requires that licensees refer to ANSI standard N510-1975 "Testing of Nuclear Air-Cleaning System" for acceptable methods of analyzing carbon samples for iodine removal efficiency.
ANSI N510-1975 requires that laboratory testing of samples be performed in accordance with RDT M 16-1T.
During a NRC inspection (November 21 to December 31,1985), a review of test results indicated that not all the requirements of RDT M 16-1T were being satisfied during the testing. This resulted in a violation of 10 CFR 50, Appendix B, Criterion V (Inspection Report 50-259, 50-260 and 50-245/85-87).
This item was W o listed as an open item under the topic, Surveillance 'e,*ing-Observation, in that report.
In response to the Inspection Report and Notice of Violation, the licensee has requested a change to the Technical Specifications in regard to the Limiting Condition for Operation (LCO) in Sections 3.78, Standby Gas Treatment System; i
3.7E, Control Room Emergency Ventilation; and 3.7F Primary Containment Purge Systen.
Specifically the requested change in the LCOs would substitute ASTM D3803 for ANSI N510-1975 in the section on radioactive methyl iodide removal testing.
88022S0268 880212 DR ADOCK 050 9
ANSI N510-1975 was revised in 1980 and the new revision was labeled as ANSI /
ASME N510-1980. ANSI /ASME N510-1980 specifically refers to ASTM D3803 as the recomended testing procedure for methyl iodide removal efficiency. ASTM D3803-79 lists detailed procedures for testing which are acceptable to the NRC staff.
Based on the above evaluation, the staff finds the proposed changes to the Technical Specificatiens acceptable.
3.0 ENVIRONMENTAL CONSIDERATION
The amendments involve a change to a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20. The staff has determined that the ar'endments involve no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no sigrificart increase in individual or cumulative cccupational radiation exposure. The Comission has previously issued a proposed finding that these amendments involve no significant hazards consideration and there has been no public comant on such finding. Accordingly, the amendments neet the eligibility criteria for categorical exclusier set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b), no environmental impact statement nor environmental assessment need be prepared in connection with the issuance of these amendments.
4.0 CONCLUSION
The staff has concluded, based on the considerations discus +d above, that: (1) there is reasenable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, and (2) such activities will be conducted in compliance with the Connission's re-gulations, and the issuance of the mendments will not be inimical to the corr.on defense and security nor to the health and safety of the public.
