ABSTRACT (Umit to 1400 spaces, i.e., approximately 15 single-spaced typewr%n'i nes) (16) l On October 6.1994. Florida Power Corporation's (FPC) Crystal River Unit 3 (CR-

3) was in MODE ONE (POWER OPERATION). operating at 100% power. It was determined that the potential existed for CR-3 to have o)erated outside plant Improved Technical Specifications (ITS) relative to the Reactor Protection  !

l System (RPS) setpoints. FPC personnel were reviewing a revised calculation when i it was discovered that RPS setpoints may not be conservative relative to ITS.

A further review of RPS setpoints determined that the Variable Low Pressure Trip (VLPT) setpoint was set at the ITS limit without provision for instrument error.

The Shutdown Bypass trip setpoint was also found to be set at its ITS limit.

This condition is reportable in accordance with 10 CFR 50.73(a)(2)(i)(B). The remainder of the RPS trip setpoints were determined to be in compliance with ITS requi rements. Subsequent evaluations determined that one Emergency Feedwater Initiation and Control System (EFIC) setpoint two Engineered Safeguards

Actuation System Bypass bistable setpoints, and instruments used to monitor i Reactor Coolant System (RCS) total flow were also potentially non-conservative  !

relative to ITS. The cause of these events was personnel error. Corrective  ;

i actions include: implementation of a setpoint action plan encompassing i recalibration. procedure changes, and assuring adequate setpoints for other actuation systems.
