ENCLOSURE e
RESPONSE TO R. C. LEWIS' LETTER DATED APRIL 24, 1980,
REFERENCE:
RII:RFS 50-259/80-19, 50-260/80-14, 50-296/80-15 INFRACTION As required by Criterion IX of Appendix B to 10 CFR 50, measures -shall be Ih established to assure that special processes, including welding heat treat-ing, and nondestructive testing, are controlled and accomplished by qualified personnel using qualified procedures in accordance with applicable codes, standards, specificat!.ona, criteria, and other special requirements. The accepted quality assuin,ce program (Topical Report TVA-TR-75-1A), states in part that TVA QA/QC Procedures requires that special processes be con-trolled and accomplished by qualified personnel using qualified written procedures.
In addition, Item 6.3.A.1 of the facility Technical Specification states that, detailed written procedures, including applicable checkoff lists covering items listed below, shall be prepared, approved and adhered to for
- preventive or corrective main *unence operation which could have an effect on the safety of the reactor.
Contrary to the above, on March 11, 1980, qualified procedures were not used for work on the High Pre ;ure Coolant Injection system (HPCI) steam line when attempting to correct a micalignment problem on the HPCI steam line by the use of heat treating.
RESPONSE
I Corrective Steps Taken And Results Achieved Corrective Action Report 80-SMM which deals with the subject infraction has been issued. All personnel were reminded that no one would work on any critical piping systems or equipment without following approved proc' dures.
e The incorrectly treated section of piping was subsequently examined, analyzed, and stress relieved under carefully, controlled procedures and conditions.
This casured that the piping was returned to an acceptable condition before placing
'IPCI back into operation.
Corrective Stops Which Will Be Taken To Avoid Further Noncompliance The procedure used was not followed completely, in that the metal temperature was not monitored as heat was applied to a section of HPCI steam piping to correct a misalignment problem.
The necessity for strict adherence to i
procedures without deviation has been stressed to all personnel.
