REQUEST FOR ADDITIONAL INFORMATION FOR THE REVIEW OF THE CRYSTAL RIVER UNIT 3 NUCLEAR GENERATING PLANT LICENSE RENEWAL APPLICATION (TAC NO. ME0274)

Dear Mr. Franke:

By letter dated December 16, 2008, Florida Power Corporation submitted an application pursuant to Title 10 of the Code of Federal Regulations Part 54, to renew the operating license for Crystal River Unit 3 Nuclear Generating Plant, for review by the U.S. Nuclear Regulatory Commission (NRC or the staff). The staff is reviewing the information contained in the license renewal application and has identified, in the enclosure, areas where additional information is needed to complete the review. Further requests for additional information may be issued in the future.

Items in the enclosure were discussed with Mr. Michael Heath, and a mutually agreeable date for the response is within 30 days from the date of this letter. If you have any questions, please contact me at 301-415-3733 or by e-mail at robert.kuntz@nrc.gov.

Sincerely,

/RA/

ENCLOSURE REQUEST FOR ADDITIONAL INFORMATION CRYSTAL RIVER UNIT 3 NUCLEAR GENERATING PLANT LICENSE RENEWAL APPLICATION DOCKET NUMBER 50-302 RAI 2.4.2.1-1 The watertight sleeves around the raw water sump vents that protect the Auxiliary Building (AB) at an elevation of 95 ft against flood levels up to an elevation of 129 ft are listed as additional components required for local protection in the Crystal River Unit 3 Nuclear Generating Plant (CR-3) AB final safety analysis report (FSAR) Section 2.4.2.4. This commodity/component is not listed in Table 2.4.2-1 of the CR-3 license renewal application (LRA) for the AB. Please justify its exclusion from the scope of license renewal.

RAI 2.4.2.3-1 As mentioned in the CR-3 LRA, the borated water storage tank (BWST) and shield wall structure include an attached reinforced concrete structure that has been abandoned but contains several components that are included in scope of license renewal, as stated in the CR-3 LRA on page 2.4-15. Clarify if this abandoned structure has been included in scope or justify its exclusion as having no impact, especially on the flood barrier capabilities on the adjacent structures that are included in scope of license renewal and therefore subject to an aging management review (AMR).

RAI 2.4.2.3-2 STYROFOAM' covers a full range of extruded polystyrene building products used primarily for insulation of floors, walls and roof systems. Please clarify if the one inch thick STYROFOAM' filler, located in the gap between the concrete missile barrier and side of the borated water storage tank, is included in scope of license renewal or justify its exclusion from the scope of license renewal.

RAI 2.4.2.3-3 The BWST is listed as a Class 1 structure per CR-3 FSAR, Section 5.1.1.1. Its foundation is made of reinforced concrete and its primary use is to support and provide missile protection to the BWST which is a mechanical component. Please clarify if this Class 1 reinforced concrete foundation is completely above grade or else justify why the below grade concrete is not listed in Table 2.4.2-3 of the CR-3 LRA, as in scope of license renewal and subject to an AMR.

RAI 2.4.2.4-1 Both bridges forming the cable bridge span the discharge canal and provide support for electrical circuits required to mitigate a postulated station blackout (SBO) event. The SBO conduits are considered to be within the cable bridge structure from where they exit the ground on one side to cross the bridge to where they re-enter the ground on the other side of the bridge. Due to the proximity to a body of water and the entrance/exit of electrical cables required to mitigate an SBO event, from the ground and their supports, please indicate if there are any seals, gaskets or any other applicable flood barriers or insulation that should be included in Table 2.4.2-4 of the CR-3 LRA, and therefore subject to an AMR.

RAI 2.4.2.4-2 In Table 2.4.2-4 for the cable bridge section of the CR-3 LRA, the cable tray, conduit, heating, ventilation, and air conditioning (HVAC) ducts and tube tracks are listed as being in scope of license renewal and therefore subject to an AMR. Please clarify if the HVAC ducts system component supports are needed and included in scope of license renewal or justify its exclusion from Table 2.4.2-4 of the CR-3 LRA.

RAI 2.4.2.8-1 Protection of the intake structure during a postulated probable maximum hurricane peak tide is provided by a cut-off wall extending downward into the competent caprock at the entrance to the structure (See CR-3 FSAR 2.4.2.4). Please confirm that this wall is considered part of the intake structure and thus included in scope of license renewal or else justify its exclusion from the scope of license renewal.

RAI 4.5-1 The fourth column of the first row in CR-3 LRA, Table 4.5-1, Summary of Tendon Data, lists the tendon force value extrapolated to the end of the period of extended operation for dome tendons as 1255 kips. However, in CR-3 LRA, Figure 4.5-1, Projected Force in Dome Tendons, the trend line based on individual lift-off forces from surveillance data indicates that the projected lift-off force in the dome tendons at the end of the period of extended operation (i.e., 63 years after initial tensioning) would be approximately 1330 kips. Please explain the discrepancy between the projected tendon force values at the end of the period of extended operation in the dome tendons indicated in CR-3 LRA, Table 4.5-1, and in CR-3 LRA, Figure 4.5-1 and identify the correct value.
