The proposed changes will delete specific differential pressure values required by SR 4.7.1.2.a.1 and SR 4.7.1.2.a.2 to prove operability of the motor-driven and the steam turbine-driven auxiliary feedwater pumps. This change is being generated as a result of removing the pressure control valves from the discharge of the motor driven auxiliary feedwater pumps. The pressure control valves were replaced with cavitating venturis. Please note that the required specific values will be contained in the appropriate plant instructions. The justification for the proposed technical specification change is provided in enclosure 2. A proposed determination of no significant hazards consideration performed pursuant to 10 CFR 50.92 is provided in enclosure 3.
