Dear r or Madam:

Pursuant to 10 CFR 50.90, Duke Energy Progress, Inc. fotmerly known as Carolin Power and Light Company, hereby requests Sn amendment to the H. B. Robinson Steam Electric Plant, Unit No. 2 (HBRSEP2) eWect facility operating license DPR-23, Appendix A,Technical Specifications.:

The proposed llcense amendment implements the NRC-approved TSTF-491, Removal of Main Steam and Main Feedwater Valve Isolation Times From Technical Specifications, via the Consolidated Line Item Improvement Process (C0IIP). This request wil modify the current HBRSEP Technical Specifications (TS) 3.7.2, Main Steam isolation Valves (MSIVs) and 3.7.3, Main Feedwatlr Isolation Valves (MFIVs), Main Feedwater Regulation Valves (MFRVs) and Bypass Valves by relocating the specific Isolation time for the isolation valves from the associated Surveillance Requirements (SR.). The specific Isolation times will be maintained In the HBRSEP2 Technical Requirements Manual (TRM).

The Enclosure provides the basis for the proposed change, including a detailed description, technical ind regulatory evaluations, environmental considerations, and the Duke Energy Progress, Inc. determination that the proposed change does not involve a significant hazards consideration. The proposed marked-up and retyped TS pages are provided in Attachments I and 2 to the Enclosure respectively. Mmrked-up TS Bases are included in Attachment 3 to the Enclosure for information.

Approval of the proposed amendment I requested by Septmber 30, 2014. Once approved, fte amendment shall be Implemented within 120 days. Ac

United States Nuclear Regulatory Commission Serial: RNP-RA/13-0077 Page 2 of 2 This proposed change has been reviewed by the HBRSEP2 Plant Nuclear Safety Committee.

3.2 Vedt AM Comminmt As discussed in the notice of availability published Inthe Federa Register on December 29, 2006 for this TS improvement, plant specific verifications were performed as follows:

The proposed change revises TS 3.7.2 and TS 3.7.3 surveillance requirements to remove specific valve Isolation times from the associated surveillances. The specific valve isolation times are replaced wth the requirements to verify the valve isolation is within limits. The specific valve *olatoiotime required to meet the surveillances is relocated outside of the TS into a document that is subject to control by the 10 CFR 50.59 process.

The Main Steam Isolation Valves, Main Feedwater Isolation Valves, Main Feedwater Regulation Valves, and Bypass Valves specific isolation times will be provided in the TRM, which is controlled by the 10 CFR 50.59 process. The proposed chwnge does not alter TS requirements for the Main Steam and Main Feedwater System isolation valves to be operable nor does, t change the TS requrent for the valves to isolate within the required time. As such, the proposed change is acceptable because Itdoes not affect the assumptions of any accident analysis or TS compliance with the requirements of 10 CFR 50.38(cX2XU). The proposed change simply adjusts the level of detail contained In TS 3.7.2 and 3.7.3 to be more consistent with the requirements of other ESF equipment required operable in the HBRSEP TS.

U@ ENVIRONMENTAL EVALUATION The amendment changes requirements with respect to the installation or use of a facility component located within the restricted area as defined in 10 CPR Pad 20. The NRC staff has determined that the amendment adop*n TSTF-491, Rev. 2, Involves no significant increase Inthe amounts and no significant changes in the types of any effluents that may be released offslte, and that there Is no significant Increase In individual or cumulative occupational radiation exposure. The Commission has previously issued a prOpoed finding that TSTF.491, Rev. 2, involves no significant hazards considerations, and there has been no public comment on the finding in Federal Register Not*c 71 FR 193, October 5, 2006. Accdig, the amend meets the eligibility criteria for categorical exclusion set forth In 10 CFR 51.22(c) (9). Pursuant to 10 CFR 51.22 (b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendment 5.0 REFERENCEs

MSIVs 83.7.2 BASES ACTIONS C.and C.2 (continued)

Condition C Is modified by a Note Indicating that separate Condition entry Is allowed for each MSIV.

Since the MSIVs are required to be OPERABLE InMODES 2 and 3, the Inogp lo MSIVs may either be restored to OPERABLE status or closed. When closed, the MSlVs are already In the position required by the assumptions In the safety analysis.

The 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> Completion Time is reasonable, oonsidering the low probability' ofan'accident occurring during this time period that would require a closure of the NSIVs.

For inoperable MSIVsthat cannot be restored to OPERABLE status within the specified Completion Time, but are closed, the inoperable MSIVs nrust bevwrified on a periodic basis to be closed. This Is necessary to ensure that the assumptions inthe safety analysis remain valid. The 7 day Completion Troe Is reasonable, based on engi mnt, in view of MSIV status indications available in the control room, and other administrave controls, to ensure that these valves are In the closed position.

Q.1 and 132 If th MSIVs cannot be"restoredto OPERABLE -Ot or are not closed w4hin the associated Completion'Time, the uri Imust be placed in a MODE in which the LCO does not apply. To achieve this st*tue the unit must be placed at least InMODE 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and in MODE 4 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. The allowed Completion Times are reasonable, basd on operatn experience, to reach the required unit conditions from MODE 2 condltions In an orderly manner and without chalienging unit systems.

BASES (continued)

SURVEILLANCE 9R 3.7.3.1  !. i REQUIREMENTS This SR verifies that the closure time of each MFRV and bypass valve Is * , on an actual or simulated actuation signal. The MFRV, and bypass valve closure times are assumed Inthe ascident and containment analyses (Ref.

2). This Surveillance is normally performed upon returning the unit to operation following a refueling outage. These valves should not be tested at power since even a part stroke exercise ncrmase the risk of a valve closure with the unit generating power. This is consistent with the ASME Code.Section X!(Ref. 3).

The Frequency for this SR Is in accordance with the Insee Testing Program. The specfied Frequency for valve closure is based on the refueling cycle. Operating experience has shown that these components usually pass the Surveillance when perfomd at the specified Frequency.

This $R verifies that the closumre time of each MFIV Is

.ehlMl~ ~ Is on an actual or simulated actuation signal.

The MFIV closure times are assumed in the accident and contairment analyses (Ref. 2). This Surveillance is normally performed upon returning the unit to operation following a refueling outage. These valves should not be tested at power since even a part stroke exercise Increases the risk of a valve closure with the unit generating power.

This Is consistent with the ASME Code,Section XI (Ref. 3).

The Frequency for this SR is In acordance with the Inservice Testing Program. The specified Frequency for valve closure is based on the refueling cycle. Operating experience has shown that these components usually pass the Surveillance when performed at the specified Frequency.
