' deference: TVA's letter to NLC dated November 17, 1987. "Sequoyah Nuclear plant (9QN) - Technical Spectfleation Change 87-40" The reference transmLtted a proposed revision to the auxiliary feedwater (AW) suction-pressure, low-trip setpoint and allowable value of table 3.3-4 (units 1 and 2) for the turbine-driven purp.

As part of their review of the proposed change, NRC has detemlnud that the logic time delays assoch:ted with the suction transfer of the turbine-driven and mo'.or-drLven AFW purps should also be included in the technical specifications.

TVA will autrmLt a proposed technical specification change to add appropriate i
