43. TLAA - Based upon the most recent fatigue analysis performed to A.3.2.2 As noted in the LRA, Metal date for the three auxiliary feedwater (AFW)-to-feedwater commitment Section 4.3 Fatigue (FW) line connections downstream of the steam-driven pump, transient limits have been reduced in the RNP RAI 4.3-2 Fatigue Monitoring Program. These reduced limits are based upon inputs used in the analysis and are more RAI 4.3-7 conservative than the original limits. The reduced limits will remain in effect until the connections are further analyzed, RAI 4.3-10 repaired, or replaced to assure the connections remain within their design basis through the period of extended operation.

Based upon the fatigue analyses performed to consider environmentally assisted fatigue, the load/unload transient limit has been reduced in the RNP Fatigue Monitoring Program. The reduced limits are based upon inputs used in the analyses and will remain in effect permanently unless the components are reanalyzed. The reduced time limit is not expected to be approached through the period of extended operation, because the original limit was established at a high value to account for load following, which is not necessary at RNP.

Further action is required for management of environmental fatigue of the surge line for the period of extended operation. Therefore, fatigue of the surge line will be managed using one or more of the following options.

1. Further refinement of the fatigue analyses to maintain the EAF-adjusted CUF below 1.0.
2. Repair of the affected locations.
3. Replacement of the affected locations.

If this option is selected, the scope, qualification, method, and frequency will be provided to the NRC for review and approval prior to the period of extended operation.

44. TLAA - In accordance with the requirements of the Environmental A.3.2.3 As noted in the LRA, Sections Environ- Qualification Program, any component that is not qualified commitment 4.4 and mental through the period of extended operation will be 4.4.1.3 Quali- refurbished or replaced prior to exceeding its qualified life.

fication Prior to the period of extended operation, certain motor-operated valve actuators will either be reevaluated to demonstrate acceptable wear-cycle qualifications or they will be replaced.

45. TLAA - To provide additional assurance of the tendons design A.3.2.4 As noted in RAI 4.5-2 Contain- capacity, testing (at integrated leak rate test pressure) commitment ment similar to the Structural Integrity Test performed in 1992 Tendon will be scheduled to coincide with Appendix J containment Loss of integrated leak rate testing conducted during the period of Prestress extended operation (required frequency in accordance with 10 CFR 50, Appendix J). The monitoring criteria for these tests will be limited to deformations and cracking associated with the vertical prestressed tendons, and will not include radial monitoring. Guidelines for performing the IWL examinations for these tests will include additional emphasis on looking for a pattern of horizontal cracks, and additional cracking in the discontinuity areas.
46. TLAA - Information from the response to RAI 4.5-1 will be A.3.2.4 Prior to the RAI 4.5-3 Contain- incorporated into Section 3.8.1.4.7 of the UFSAR. This will period of ment include initial average prestressing force, losses, and final extended Tendon average prestressing force at 50 and 60 years as operation Loss of discussed in the response to RAI 4.5-1. This commitment Prestress supersedes the proposed changes shown on LRA Page A-6 for UFSAR Section 3.8.1.4.7.

47. TLAA - Prior to the period of extended operation, the Boraflex A.3.2.8 Prior to the LRA, Section Aging of Monitoring Program will be modified to (1) include neutron period of 4.6.4 Boraflex in attenuation testing, called blackness testing, to determine extended Spent Fuel gap formation in Boraflex panels; (2) include trending the operation RNP-RA/03-Pool results for silica levels by using the EPRI RACKLIFE 0154 predictive code or equivalent, and (3) include measurements of boron areal density by techniques such as the BADGER device, RNP has requested, by letter dated May 28, 2003, Serial: RNP-RA/03-0038, an amendment to the Technical Specifications to eliminate the need to credit Boraflex neutron absorbing material for reactivity control. The Boraflex Monitoring Program will be eliminated upon NRC approval of this amendment or upon implementation of another option(such as re-racking the spent fuel pool) which eliminates the need to credit Boraflex for reactivity control.
