Dear Mr. O'Reilly:
SEQUOYAH NUCLEAR PLANT UNITS 1 AND 2 - NRC-0IE LETTER RII:WHH 50-327/79-34 AND 50-327/79 ADDITIONAL INFORMATION ON DEVIATION ITLi The subject letter dated October 31, 1979, cited TVA with three deviations in accorda:~ce witn 10 CFR 2.201.
My letter to you dated November 21, 1979, transmitted our response to those deficiencies.
Enclosed is additional information requested by Inspector W. H. Miller during his inspection on May 13-15, 1980.
This information is in relation to deviation item 50-327/ 79-34-03 and 50-328/79-19-03, Inadequate QA Documentation of Inspections and Tests Conducted on Fire Protection System Installations.
If you have any questions concerning this matter, please get in touch with D. L. Lambert at FTS 854-2581.
Very truly yours, TENNESSEE VALLEY AUTHORITY L. M. Mills, Manager Nuclear Regulation and Safety Enclosure Mr.VictorStallo,Jr., Director (Enclosure)/

4 ENCLOSURE SEQUOYAH NUCLEAR PLANT UNITS 1 AND 2 ADDITIONAL INFORMATION ON NRC INSPECTION DEVIATION ITEM 50-327/79-34-03 AND 50-328/79-19-03 INADEQUATE QA DOCUMENTATION OF INSPECTIONS AND TESTS CONDUCTED ON FIRE PROTECTION SYSTEM INSTALLATIONS TVA believes the test data provided for the hydrostatic tests and flushes conducted on the fire protection systems to be adequate and in full con-formance with the commitments in Revision 4 of TVA's responses to Quality Assurance Branch Request for Additional Information item F421.1 (C.5).
These tests were witnessed by qualified engineering employees representing the Division of Construction, thereby providing the degree of autonomy to achieve compliance with the commitments in the above referenced responses, items F421.1 (C.4) and (C.5).
Hydrostatic t asts were performed in accordance with design requirements and National Fire Protection codes and were documented with engineering records showing hydrostatic test boundaries on fire protection flow diagrams.
Flushing of the fire protection system was accomplished in accordance with TVA Ceneral Construction Specification G-39 and documented in the same manner as the hydrostatic tests.
SNP Construction Procedure P-43, Installation Inspection-Fire Protection Systens, was revised on November 9, 1979, to include requirements for independent inspection of hydrostatic testing and flushing operations.
Records of hydrostatic testing and flushing have been maintained by the Division of Nuclear Power for portions of the system which have been modified since the initial flushes were conducted.
Subsequent preopera-tional testing of the system has accomplished additional flushes of most of the system and has not revealed the presence of any foreign material in the piping systems.
TVA believes the above to be evidence of the fact that adequate hydrostatic testing and flushing of the fire protection system has been accomplished.
