REVIEW 0F TECHNICAL SPECIFICATION 5.7 In the process of reviewing the CPSES Unit I draft Technical Specifications during the February 14, 1989, TV Electric /NRC meeting, the NRC staff requested l

that TV Electric address the difference between proposed Table 5.7-1, Component Cyclic or Transient Limits, and FSAR Table 3.9N-1, Summary of Reactor Coolant System Design Transients.

The NRC staff also requested that the monitoring of transients not listed in Table 5.7-1 be addressed.

Table 5.7-1 lists those limiting reactor coolant system design transients l

i which would require an amendment to the Operating License to change.

The CPSES proposed table is in accordance with Standard Technical Specifications, t

Table 3.9N-1 summarizes reactor coolant design transients for Normal, Upset, Emergency, Faulted, and Test conditions.

Table 3.9N-1 includes those transients considered in the fatigue evaluation.

EPRI has been active by developing fatigue cycle monitoring programs to l

support design life extension and technical specification compliance.

The Westinghouse Owner's Group (WOG) is currently developing general guidelines for nuclear power plant transient and fatigue monitoring.

3 TXX-89119 February 27, 1989 Page 2 of 2 TV Electric recognizes the importance of monitoring both technical specification and fatigue significant transients. Once industry guidance is-available, TV Electric will develop a program to monitor additional fatigue significant transients in accordance with such guidance to assure cyclic stress limits are not exceeded.
