OPERATING LICuiSE OP457 EDWIN 1. HATCH N ELEAR P M UNIT 1 i

l REQUEST F09 CHAN3E5 TO TEC+lICAL SPECIFICATI0t@

i Cetlemem f

l Pursuant to 10 CFR 50,90, Georgia Power Coepany hereby requests two j

changes to the Technical Specifications (Appendix A to Operating License 1

DF4 57).

The first proposed chang adds two fuel types to Specification 3.11. A, which sets M4PLHQR operating limits.

The justification for these two additional HAPLKR curves.is provided in enclosure 1, Errata and Addenda Sheet for NEDO-24006, LOCA A% lysis for Edwin I. Hatch H> clear Plant thit l*

ditch we also sutxnit at this time.

We have evaluated the results given in this (pdate to the Hatch 1 ECCS document and believe these HV'LHGR limits to j

be conservative for operation of these fuel types in Hatch 1.

Tin secured proposed change increases the Rod Block ntnitor setpoint to 107E and increases the KPR limit for all fuel typ(es to 1.29.

The KFR.

limit ircrease la based on General Electric's CE) new generic md

' withdrawal error (RWE) analysis procedure as sitaitted from E to the IRC by letter of May 18, 1981.

The new method' for HWE analysis sets the transient change in critical power ratio ( CPR) for the potential worst rod withdrowal error etpal to the 95/95 statistical value of limiting CPR's from 40 arAlyses with the previous nethod. The new nethod provides CPR/1CPR es a function of Ibd Block Monitor (ROM) setpoint.

The CPR/ICPR can bei algebraically manipulated to provide the MCPR operating limits necessary to maintain the MCfR above the safety limit in the event of rod withdrawal error.

An advantage of the new wcthod is that the operating limits are independent of the fbel cycle, which will elitninate the uncertainty of future RWE analysis results and will facilitate 10 CFR $0.59 reload submittals. Tre 95/95 value of maxinum linear heat generation rate (kW/Ft) was shown to be consistently I

less than the current transient limits (1% plastic strain), and therefore, will not be reported onder the new procedJres.
