Dear Sir:

On July 18, 2007, the Nuclear Regulatory Commission (NRC) issued a Request for Additional Information (RAI, Reference 2) regarding License Amendment Request (LAR) #295 (Reference 3). On September 4, 2007, Florida Power Corporation (FPC), doing business as Progress Energy Florida, Inc.,

issued a response to this RAI (Reference 1). Subsequent to submittal of the RAI response, the NRC has asked two follow-up questions informally about the response. In accordance with the provisions of 10 CFR 50.90, FPC hereby provides the response to the RAI.

This letter revises regulatory commitments made in References 1 and 3. The revised commitments in Attachment B to this letter replace the commitments in References 1 and 3 in their entirety.

If you have any questions regarding this submittal, please contact Mr. Paul Infanger, Supervisor, Licensing and Regulatory Programs at (352) 563-4796.

CRYSTAL RIVER UNIT 3 DOCKET NUMBER 50-302 / LICENSE NUMBER DPR-72 LICENSE AMENDMENT REQUEST #295, REVISION 0 EXTENSION OF ALLOWED OUTAGE TIME TO SEVEN DAYS AND ELIMINATION OF SECOND COMPLETION TIMES ATTACHMENT A RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION

U.S. Nuclear Regulatory Commission Attachment A 3F0907-07 Page 1 of 2 Request for Additional Information Response On July 18, 2007, the Nuclear Regulatory Commission (NRC) issued a Request for Additional Information (RAI, Reference 2) regarding License Amendment Request (LAR) #295 (Reference 3). On September 4, 2007, Florida Power Corporation (FPC), doing business as Progress Energy Florida, Inc., issued a response to this RAI (Reference 1). Subsequent to the submittal of the RAI response, the NRC has asked two follow-up questions informally about the response. FPC hereby provides the following response to this RAI.

NRC Request

1.

The Crystal River 3 (CR-3) response to RAI 6 in Reference 1 regarding fire risk identified six bulleted items for fire areas which are "sensitive" to fire risk (page 8 of 16 in Attachment 1).

However, only one of the bulleted items in this list is addressed in the regulatory commitments (the first, for the Decay Heat Removal

[DH], Decay Heat Closed Cycle Cooling [DC] and Raw Water [RW-DC] rooms, which appears to be addressed by commitments four and five of Attachment B). It appears that CR-3 has identified fire areas as being important to fire risk, but then proposes no action be taken. Since CR-3 did not provide the specific contribution of each fire area to the calculated fire risk, it is not able to conclude that the compensatory measures proposed have any significant mitigating impact on the fire risk. Therefore, this information needs to be provided, and CR-3 needs to include all the identified fire areas in the scope of its compensatory measures.

FPC Response

1.

From Reference 1, the text described above is as follows:

The following fire areas showed they were sensitive to fire risk in conjunction with a DH

[Decay Heat Removal], DC [Decay Heat Closed Cycle Cooling], BS [Reactor Building Spray] and RW-DC [Decay Heat Seawater] system outage:

The opposite train DH, DC, and RW-DC rooms.

The opposite train MCC room (480VAC and 4160 VAC).

Non-Safety 4160VAC and 480VAC rooms.

The opposite train battery and charger rooms.

The opposite train Inverter rooms.

Remote Shutdown Room.

These areas were identified in the revised fire assessment performed to support the CR-3 response to the NRC's recent RAI (Reference 2). FPC agrees that fire watches for these areas should be included in the List of Regulatory Commitments. This list has been revised to include fire watches for the above areas during all periods of extended outage (greater than 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />) for the DH, DC, BS or RW-DC Systems.

For pre-planned extended outages, the compensatory measures will be in place for the entire system outage period. For unplanned extended outages, the compensatory measures will be put in place as soon as practical once it is known the system outage will exceed 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.

U.S. Nuclear Regulatory Commission Attachment A 3F0907-07 Page 2 of 2 NRC Request

2.

In addition, a "periodic" fire watch has been identified for "planned" outages in the regulatory commitments in Attachment B. "Periodic" needs to be defined, and this should be applied to any use of the extended CT, not just planned uses.

FPC Response

2.

The use of the term "periodic" to describe the frequency for fire watches is meant to be consistent with the Fire Watch Program at CR-3, described in Administrative Instruction 2210, "Fire Watch Program."

The Program states that it is the Fire Watch's responsibility to inspect assigned areas at least once per hour with a margin of fifteen minutes.

FPC agrees that a periodic fire watch should be used for any extended outage, regardless of whether it is planned or not. As such, the commitments in Attachment B have been revised to state that the compensatory measures apply to all extended outages (greater than 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />), whether they are scheduled or emergent.

Commitment Due Date CR-3 will perform procedure CP-253, "Power Operation Risk During extended (greater than Assessment and Management,"

which requires both a 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />) outage on the LPI, deterministic and probabilistic evaluation of risk for the BS, DC or RW-DC System performance of all maintenance activities.
