ROBINSON STEAM ELECTRIC PLANT, UNIT NO. 2 DOCKET NO. 50-261/LICENSE NO. DPR-23 SHEARON HARRIS NUCLEAR POWER PLANT DOCKET NO. 50-000/LICENSE NO. NPF-63 BORIC ACID CORROSION OF, CARBON STEEL REACTOR PRESSURE BOUNDARY COMPONENTS IN PWR PLANTS (GENERIC LETTER 88-05)

Gentlemen:

Carolina Power k Light Company (CPrtt:L) hereby submits its response to Generic Letter 88-05 (GL88-05) in accordance with the provisions of 10CFR50.50 (f).

CPrst:L does.not currently have a formal program to address the concerns and elements identified in GL88-05 for the H. B. Robinson Steam Electric Plant (HBR2) or Shearon Harris Nuclear Power Plant (SHNPP). However, as a result of experience at HBR2 and within the industry, CPRL has taken a positive approach toward the reduction of boric acid-induced corrosion. Examples of this at HBR2 include closely monitoring detectable leakage (inclusive of leakage rates at less than technical specification limits) and providing status to management should a change in trend occur, inspections for boric acid buildup during refueling outages, instituting a preventative valve repacking program, and torque requirement controls.

Although SHNPP has not yet completed its first operating cycle, significant efforts to prevent boric acid corrosion have been taken based on the review of applicable industry operating experience and NRC notices and bulletins. In particular, maintenance procedures for borated and non-borated water systems include torque requirements and bolt/stud inspection requirements for various sizes and grades of bolting. In addition, the plant performs daily reactor coolant system water inventory balance to calculate identified and unidentified leakage rates. This'information is trended and reported to plant management when adverse conditions are noted.

CPRL agrees that a formal program governing boric acid corrosion is appropriate. A formal program which builds upon existing provisions at HBR2 and SHNPP is currently being developed to comply with the provisions of GL88-05 for both units and will be completed and implemented by 3anuary 1, 1989.
