==Dear Sir:==
Pursuant to the referenced document, Florida Power Corporation (FPC), doing business as Progress Energy Florida, Inc., submitted License Amendment Request (LAR) #295 which proposed changes to the Crystal River Unit 3 (CR3) Improved Technical Specifications (ITS) to allow the deletion of second completion times. Included in the referenced document was a discussion of administrative controls. As a result of a telecon conducted on January 30, 2008, between the NRC Project Manager and CR3 Licensing personnel, FPC is providing additional information related to administrative controls proposed by LAR #295.

However, doing so would be inconsistent with the basis of the Completion Times.

Subject:

Crystal River Unit 3 - License Amendment Request #295, Revision 0: Extension of Allowed Outage Time to Seven Days and Elimination of Second Completion Times - Response to Request for Additional Information (TAC No. MD5241)

Reference:

CR3 to NRC letter dated April 13, 2007, "Crystal River Unit 3 -

License Amendment Request #295, Revision 0, Extension of Allowed Outage Time to Seven Days and Elimination of Second Completion Times Limiting Time"

Dear Sir:

Pursuant to the referenced document, Florida Power Corporation (FPC), doing business as Progress Energy Florida, Inc., submitted License Amendment Request (LAR) #295 which proposed changes to the Crystal River Unit 3 (CR3) Improved Technical Specifications (ITS) to allow the deletion of second completion times. Included in the referenced document was a discussion of administrative controls. As a result of a telecon conducted on January 30, 2008, between the NRC Project Manager and CR3 Licensing personnel, FPC is providing additional information related to administrative controls proposed by LAR #295.

Page 3 of Enclosures C and D of the referenced document proposes to revise ITS Example 1.3-3 by eliminating the second Completion Times and replacing the discussion regarding second Completion Times with the following text:

"It is possible to alternate between Condition A, B, and C in such a manner that operation could continue indefinitely without ever restoring systems to meet the LCO. However, doing so would be inconsistent with the basis of the Completion Times. Therefore, there shall be administrative controls to limit the maximum time allowed for any combination of Conditions that result in a single contiguous occurrence of failing to meet the LCO.

These administrative controls shall ensure that the Completion Times for those Conditions are not inappropriately extended."

The administrative controls described in the above insert will be captured by the following new licensing basis commitment:

U.S. Nuclear Regulatory Commission 3F0208-01 Page 2 of 3 There shall be administrative controls to limit the maximum time allowed for any combination of Conditions that result in a single contiguous occurrence of failing to meet the LCO for ITS 3.6.6, Reactor Building Spray and Containment Cooling Systems, ITS 3.7.5, Emergency Feedwater (EFW) System, ITS 3.8.1, AC Sources - Operating, and ITS 3.8.9, Distribution Systems - Operating. These administrative controls shall ensure that the Completion Times for those Conditions are not inappropriately extended.

The administrative controls will ensure that Completion Time is NOT extended beyond the additive Completion Times of the two Required Actions for restoration of OPERABILITY unless a risk evaluation is performed. If unit operation within an LCO will exceed the maximum Completion Time, then either the shutdown Condition within the LCO should be entered OR a risk evaluation shall be performed and the risk impact managed under CP-253, "Power Operation Risk Assessment and Management."

The attachment to this letter contains a list of all the regulatory commitments associated with LAR #295, Revision 0. The commitment above is included in this list.

The No Significant Hazards Considerations provided in the referenced document remains valid and is not changed by this submitttal.

If you have any questions regarding this submittal, please contact Mr. Dennis Herrin, Acting Supervisor, Licensing and Regulatory Programs at (352) 563-4633.

These administrative controls shall ensure that the Completion Times for those Conditions are not inappropriately extended.

The administrative controls will ensure that Completion Time is NOT extended beyond the additive Completion Times of the two Required Actions for restoration of OPERABILITY unless a risk evaluation is performed. If unit operation within an LCO will exceed the maximum Completion Time, then either the shutdown Condition within the LCO should be entered OR a risk evaluation shall be performed and the risk impact managed under CP-253, "Power Operation Risk Assessment and Management."

This will be implemented in conjunction with the license amendment.
