DESCRIPTION OF REQUEST:

This submittal requests that reactor vessel fluence-dependent ,

pressure and temperature limits be removed from Technical '

Specifications (TS) and relocated to a Pressure / Temperature Limits Report. The term, PRESSURE / TEMPERATURE LIMITS REPORT, will be  :

added to the Definitions Section of TS. A new administrative ,

reporting requirement will be added to existing reporting i requirements of TS. The individual specification and applicabla .

Bases will be revised to state that the values of reactor vessel l pressure /temperaure parameters shall be maintained within the .

limits identified in the Pressure / Temperature Limits Report.  !

RERSON FOR REQUEST >

l Technical Specifications (TS) address pressure and temperature  !

limits associated with parameters that generally change with reactor vessel fluence requiring the processing of changes to TS -

to update these limits each fuel cycle. These limits are developed using an NRC-approved methodology, therefore, the license amendment  !

process is an unnecessary burden on the licensee and the NRC. An alternative to including the values of these reactor vessel fluence-dependent parameters in individual specifications is responsive to industry and NRC efforts on improvements in TS and is provided in this change request.  ;

t i r

,, e .'

4 g EVALUATION OF REQUE8it It is essential to safety that the plant is operated within the bounds of pressure / temperature limits and that a requirement to maintain the plant within the appropriate bounds must be retained in the TS. However, the specific values of these limits may be modified by licensees, without affecting nuclear safety, provided that these changes are determined using an NRC-approved methodology and consistent with all applicable limits (e.g., heatup limits, cooldown limits, inservice leak and hydrostatic testing limits).

A pressure / Temperature Limits Report will be submitted to NRC with the values of these limits. This will allow continued trending of this information, even though prior NRC approval of the changes to these limits would not be required. The Pressure / Temperature Limits Report will documer.t the specific values of parameter limits resulting from the licensee's calculations including any revisions to such parameter values. The methodology for determining pressure / temperature limits is documented in NRC-approved Topical Report BAW-10046A, Rev. 2, " Methods of Compliance With Fracture Toughness and Operational Requirements of 10CFR 50, Appendix G",

June 1986. As a consequence, the NRC review of proposed changes to TS for these limits is primarily limited to confirmation that the updated limits are calculated using an NRC-approved methodology and consistent with all applicable limits of the safety analysis.

The pressure / temperature limits calculated in accordance with the approved' methodology will be included in a report, Pressure / Temperature Limits Report, and provided to the NRC upon issuance as required by the proposed Technical Specification 6.9.1.7. Controlled copies of the Pressure / Temperature Limits Report will be maintained at Crystal River Unit-3 (CR-3) and will be revised as required by the future CR-3 reactor vessel fluence periods. Attachment 1 provides a sample copy of a 15 EFPY l Pressure / Temperature Limits Report for information purposes only.

.,, e' SNOLLY EVALUATION OF REQUEST: j Florida Power Corporation (FPC) proposes the removal of pressure / l temperature limits from Technical Specifications does not involve l a significant hazard consideration. The removal of the fluence  ;

dependent variables from Technical Specifications has no impact '

upon plant operation or safety. The Technical Specification will ,

continue to require operation within the pressurc/ temperature i limits for each cycle reload calculated by the approved reload design methodology. Appropriato actions to be taken if limits are violated will also remain in Technical Specifications.  !

FPC concludes this change will not:  !

1. Involve a significant increase in the probability or consequence of an accident previously evaluated because the ,

removal of pressure / temperature limits from the Crystal River i Unit 3 (CR-3) Technical Specifications has no influence or impact on the probability of a Design Basis Accident (DBA) 1 occurrence.

The cycle specific pressure / temperature limits will be relocated to a PRESSURE / TEMPERATURE LIMITS REPORT. The requirements to operate CR-3 within the limits will continue to be maintained in Technical Specifications.

2. Create the possibility of a new or different kind of accident from any accident previously evaluated because the removal of the fluence dependent variables has no influence, impact, nor does it contribute to the probability cr consequences of an accident. The fluence dependent variables are calculated using an NRC approved methodology, and Technical Specifications will continue to require the operation within the pressure / temperature limits.
3. Involve a significant reduction in the margin of safety because the margin of safety presently provided by current Technical Specifications remains unchanged. This proposed amendment still requires operation within the pressure /

temperature limits as obtained from the NRC approved methodology, and appropriate actions to be taken when, or if ,

limits are violated, remain unchanged.
