U.S. Nuclear Regulatory Commission Document Control Desk Vashington, D.C. 20555 Attn: T.E. Hurley December 4, 1992

Dear Dr. Hurley:

This letter is vritten to submit changes to the Cook Nuclear Plant Unit 2 Data Point Library that, vere discovered during internal ERDS testing. The specific changes are outlined belov. These changes vere discussed vith Hr. J. R. Jolicoeur of your staff on November 17, 1992. The Unit 2 Data Point Library vas originally submitted in our letter AEP:NRC:1163A dated June 17, 1992.

The necessary revisions are as follovs:

The alarm/trip setpoint for reactor coolant system pressure vas omitted. It should be 425 PSIG lov.

2. The alarm/trip lov setpoint for the primary system charging or makeup flov vas given as 40.0 GPH high.

It should be 40.0 GPH lov.

Attached are the revised pages to the Unit 2 Data Point Library that incorporate the above changes.
