REQUEST FOR ADDITIONAL INFORMATION ST LUCIE NUCLEAR PLANT, UNIT NO. 1 STEAM GENERATOR TUBE INTEGRITY TECHNICAL SPECIFICATION AMENDMENT DOCKET NO. 50-335 By letter dated April 24, 2006, Florida Power & Light Company requested an amendment to the St. Lucie Nuclear Plant, Unit 1, technical specifications (TSs) requirements regarding steam generator tube integrity, based on TS Task Force traveler TSTF-449.
The U.S. Nuclear Regulatory Commission (NRC) staff has reviewed this request and finds that the following additional information is needed to complete the review.
1.
On page 13 of Attachment 2 of the submittal, the proposed revision to TS 3.4.6.1 adds the statement... per Surveillance Requirement 4.4.6.2.c.... under Actions a and b.
The purpose of adding this statement is not clear, since Surveillance Requirement (SR) 4.4.6.2.c has no additional details. In addition, the action statements require the reactor coolant system water inventory balance to be performed at least once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, which appears to conflict with the 72-hour requirement stated in the current SR 4.4.6.2.c. Please explain the purpose of adding this statement or discuss your plans to remove it.
The remaining questions relate to the proposed TS Bases in Attachment 4 of the submittal.
2.
The current Bases for TS 3/4.4.6.2 (shown on page 11) states that the dosage contribution from the tube leakage will be limited to a small fraction of Title 10, Code of Federal Regulations (10 CFR) Part 100 dose guideline values. The proposed revisions on pages 6 and 12 state that the dose consequences are within the limits of 10 CFR Part 100 and 10 CFR 50.67. Please clarify whether your current NRC-approved accident source term is based on Part 100 (as referenced in the current TS Bases),
10 CFR 50.67 or both?
3.
On page 12, in the proposed insert to B3/4.4.6.2, there appear to be two words missing from the second sentence of the third paragraph. The sentence currently reads:
Therefore, monitoring reactor coolant leakage... The sentence should read:
Therefore, detecting and monitoring.... according to the Standard TSs. Please discuss your plans to add these two words to the proposed TS Bases.
4.
On page 6, the last sentence of the second paragraph currently reads:... or the NRC approved licensing basis (e.g., a small fraction of these limits). However, on page 12, the same sentence appears in the last paragraph but the statement included in the parentheses is missing. Please discuss your plans to add this statement in this section.
Enclosure 5.
There are several proposed changes to the Bases for TS 3/4.4.6, Reactor Coolant System Leakage, that go beyond TSTF-449. Please confirm that all of the proposed changes are consistent with your current NRC-approved design and licensing bases. If they are not consistent, please provide a technical justification for the differences or discuss your plans to remove them.
6.
On page 9, the proposed Bases for TS 3.4.5, Actions a.1 and a.2, indicate that the affected tubes(s) must be plugged prior to entering HOT STANDBY. However, the corresponding requirement of TS 3.4.5 is to plug the tube(s) before entering HOT SHUTDOWN. Please discuss your plans to modify this statement.
7.
Under Item d on page 13, there appears to be a typographical error in the first sentence. It appears that with should be within. Please discuss your plans to correct this error.
8.
On page 14, the proposed Bases associated with TS 3.4.6.2, Action b, does not address the need to be in Hot Standby within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and Cold Shutdown within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br /> in the event that unidentified or identified leakage cannot be reduced to within limits within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />. Please discuss your plans to modify the proposed Bases to address this issue.
