POWER AUTHORITY OF THE STATE OF NEW YORK JAMES A. FITZPATRICK NUCLEAR POWER PLANT DOCKET N0. 50-333 ATTACHMENT TO LER 79-093/03L-0 Page 1 of 1 During normal operation, Operations personnel noted that a routine computer print out of the core performance log indicated that the Core Maximum Fraction of Limiting Power Density (CMFLPD) was 1.003 compared to a Technical Specification limit of equal to or less than 1.000.

Reactor power was immediately reduced approximately 2% in accordance with the requirements of Technical Specifications, Appendix A, Paragraph 4 .1. B . This action restored CMFLPD to within the limits of Technical Specifications within the t19e frame allowed and is considered to be equivalent to operation in a degraded mode.

Following the initial power reduction, the core performance log was again demanded from the plant's process computer and revealed that CMFLPD was within specifications. Control rod pattern adjustuents were made and approximately two hours later, power was-restored to between 99 and 100%

of rated power. A core performance log demanded following the power increase revealed that CMFLPD was within spec,1fications. ..

The event did not represent a significant hazard to the public health and safety.
