HATCH NUCLEAR PLANT UNIT 1 POST-WELD OVERLAY REPAIRS TESTING Gentlemen:

Our submittal dated December 10, 1984 discussed repair activities conducted during the 1984 Unit 1 refueling outage. We. indicated therein

-that a hydrostatic test was scheduled to be conducted following weld overlay of certain piping welds in the Recirculation and Residual Heat Removal systems which had been found to have crack-like indications. Hydrostatic testing following such repairs would normally be performed per ASME- Section XI Code requirements by either removing the from service or gagging . those valves and enthMain Steam pressurizing thesafety system./ relief A ' valve review of Hatch Unit 1 Technical Specificatioi

• 2.A.1 indicates, however, that the safety / relief valves are required to be operable when irradiated fuel is present in the vessel and the vessel head is installed. As a result of this limitation, a hydrostatic test cannot be performed.

IWA-5214(d) of the 1980 Edition of the ASME Section XI Code with Addenda through Winter 1980 states that when a hydrostatic test performed as a result of repairs conflicts -with the Technical Specifications, a system inservice test -is acceptable in lieu of the hydrostatic test. It is our position that this code provision may be applied in the case of the Unit I repair. The appropriate systems will, therefore, be visually examined while in service at operating pressure rather. than hydrostatically tested as

,previously planned.
