The purpose of this letter is for the Nebraska Public Power District (NPPD) to submit a request for amendment to the Technical Specifications (TS) for Cooper Nuclear Station (CNS) in accordance with the provisions of 10 CFR 50.90. | |||
The proposed amendment would delete TS 5.5.3, "Post Accident Sampling," thereby eliminating the program requirements to have and maintain the post accident sampling system at CNS. The changes are consistent with Nuclear Regulatory Commission (NRC) approved Industry/Technical Specification Task Force (TSTF) Standard Technical Specification Change Traveler, TSTF-413, "Elimination of Requirements for a Post Accident Sampling System (PASS)." The availability of this technical specification improvement was announced in the Federal Register on March 20, 2002, as part of the consolidated line item improvement process (CLIIP). CNS will continue to have the ability to obtain samples, utilizing PASS, following an accident. | |||
The submittal was prepared in accordance with the CLIIP example application. Attachment 1 provides a description of the proposed change, the requested confirmation of applicability, and plant-specific verifications. Attachment 2 provides the existing TS pages marked-up to show the proposed change. Attachment 3 provides revised clean TS pages. Attachment 4 provides the existing TS Bases pages marked-up to show the proposed change (for information only). provides a summary of the regulatory commitments made in this submittal. | |||
NPPD requests approval of the proposed License Amendment by July 14, 2015, with the amendment being implemented within 60 days following approval. | |||
This proposed TS change has been reviewed by the necessary safety review committees (Station Operations Review Committee and Safety Review and Audit Board). | |||

== | ==1.0 DESCRIPTION== | ||
The proposed license amendment deletes the program requirements of Technical Specification (TS) 5.5.3, "Post Accident Sampling." Revision of TS 5.5.2, Systems Integrity Monitoring Program, is not needed since it contains no discussion of Post-Accident Sampling System (PASS). | |||
The changes are consistent with Nuclear Regulatory Commission (NRC) approved Industry/Technical Specification Task Force (TSTF) Standard Technical Specification Change Traveler, TSTF-413. The availability of this TS improvement was announced in the Federal Register on March 20, 2002, as part of the consolidated line item improvement process (CLIIP). | |||
2.0 ASSESSMENT 2.1 Applicability of Published Safety Evaluation Nebraska Public Power District (NPPD) has reviewed the safety evaluation published on December 27, 2001 (66 FR 66949), as part of the CLIIP. This verification included a review of the NRC staffs evaluation (as modified slightly by the notice of availability) as well as the supporting information provided to support TSTF-413 (i.e., NEDO-32991, "Regulatory Relaxation for BWR Post Accident Sampling Stations (PASS)," submitted November 30, 2000, and the associated NRC Safety Evaluation (SE) dated June 12, 2001). | |||
NPPD has concluded that the justifications presented in the TSTF proposal and the SE, prepared by the NRC staff, are applicable to Cooper Nuclear Station (CNS) and justify this amendment for the incorporation of the changes to the CNS TS. | |||
2.2 Optional Changes and Variations NPPD is not proposing any variations or deviations from the TS changes described in TSTF-413 or the NRC staffs model SE published on December 27, 2001. | |||
Note 2 of the December 27, 2001 NRC SE identified three other potential TS changes for which the staff provided discussion. For CNS, applicability is as follows: | |||
(1) Editorial changes No editorial changes to CNS TS are required to account for the changes covered in this request. The proposed TS reflect Subsection 5.5.3 as "Deleted." The remaining subsections in Section 5.5 are not renumbered. | |||
NLS2014035 Attachment I Page 3 of 4 (2) Mention of PASS as a potential leakage source outside containment NPPD plans to leave PASS in place. Therefore, the configuration of PASS will continue to be a potential leakage path outside the Primary Containment for highly radioactive fluids. Any PASS leakage would be included in the cumulative allowed Emergency Core Cooling System leakage. | |||
TS Subsection 5.5.2, Systems Integrity Monitoring Program, provides for a program to minimize leakage from those portions of systems outside containment that could contain highly radioactive fluids during a serious transient or accident. PASS is not mentioned in the scope of this program. Therefore, no revision to TS 5.5.2 is needed. | |||
(3) TS Bases changes The elimination of PASS results in changes to the discussion in the TS Bases section B 3.3.6.1, Primary Containment Isolation Instrumentation. Item number 2.e, Reactor Vessel Water Level - Low Low Low (Level 1), discusses bypassing this function in order to obtain a sample for PASS. The specific mention of "PASS" is replaced with a reference to "core damage assessment capability." The proposed Bases revisions are provided in Attachment 4. NPPD will formally address the change to the TS Bases in accordance with the TS Bases Control Program of TS Section 5.5.10, and will provide the actual revised TS Bases pages in a future submittal required by 10 CFR 50.71(e). | |||
No change to TS Bases B 3.3.3.1, Post Accident Monitoring (PAM) Instrumentation, is necessary since the current TS Bases do not mention PASS. | |||
==3.0 REGULATORY ANALYSIS== | |||
3.1 Applicable Regulatory Requirements/Criteria Construction of CNS predated the 1971 issuance of 10 CFR 50, Appendix A, "General Design Criteria for Nuclear Power Plants." Appendix F, "Conformance to AEC Proposed General Design Criteria," of the CNS Updated Safety Analysis Report discusses that CNS is designed to conform to the proposed general design criteria (GDC) published in the July 11, 1967, Federal Register, except where commitments were made to specific 1971 GDC. It notes that the Atomic Energy Commission (AEC) accepted CNS conformance with these proposed GDC. | |||
This difference does not alter the conclusion that the proposed change is applicable to CNS. | |||
NLS2014035 Attachment I Page 4 of 4 3.2 No Significant Hazards Consideration Nebraska Public Power District (NPPD) has reviewed the proposed no significant hazards consideration determination published on December 27, 2001 (66 FR 66949), as part of the consolidated line item improvement process. NPPD has concluded that the proposed determination presented in the notice is applicable to Cooper Nuclear Station and the determination is hereby incorporated by reference to satisfy the requirements of 10 CFR 50.91(a). | |||
3.3 Verification and Commitments As discussed in the model SE published in Federal Register (FR) on December 27, 2001, for this TS improvement, plant-specific verifications were performed as follows: | |||
: 1. NPPD verified it has contingency plans for obtaining and analyzing highly radioactive samples from the reactor coolant system, suppression pool, and containment atmosphere. NPPD will maintain this capability in CNS Chemistry Department procedures. Implementation of this commitment is complete. | |||
: 2. NPPD verified it has established the capability for classifying fuel damage events at the Alert level threshold for CNS at radioactivity levels of 300 ACi/cc dose equivalent iodine. This capability is described in the Emergency Plan Implementing Procedure for performing dose projection. Implementation of this commitment is complete. | |||
: 3. NPPD verified that it has an l-131 site survey detection capability, including an ability to assess radioactive iodines released to offsite environs, by using effluent monitoring systems or portable sampling equipment. The capability for monitoring iodines will be maintained in the Emergency Plan Implementing Procedures for manually determining airborne release rates and for onsite and offsite boundary monitoring. Implementation of this commitment is complete. | |||
4.0 ENVIRONMENTAL EVALUATION NPPD has reviewed the environmental evaluation included in the model safety evaluation published on December 27, 2001 (66 FR 66949), as part of the CLIIP. NPPD has concluded that the NRC staff s findings presented in that evaluation are applicable to CNS and the evaluation is hereby incorporated by reference for this application. | |||

If the steam is allowed to continue flowing out of the break, the reactor will depressurize and the core can uncover. Therefore, the isolations are initiated on high flow to prevent or minimize core damage. The isolation action, along with the scram function of the RPS, ensures that the fuel peak cladding temperature remains below the limits of 10 CFR 50.46. Specific credit for these Functions is not assumed in any USAR accident analyses since the bounding analysis is performed for large breaks such as recirculation and MSL breaks. However, these instruments prevent the RCIC or HPCI steam line breaks from becoming bounding. | |||
The HPCI and RCIC Steam Line Flow-High signals are initiated from differential pressure switches (two for HPCI and two for RCIC) that are connected to the system steam lines. A time delay is provided to prevent HPCI or RCIC isolation due to high flow transients during HPCI or RCIC startup with one Time Delay Relay channel associated with each Steam Line Flow-High channel.

1.0 DESCRIPTION
The proposed license amendment deletes the program requirements of Technical Specification (TS) 5.5.3, "Post Accident Sampling." Revision of TS 5.5.2, Systems Integrity Monitoring Program, is not needed since it contains no discussion of Post-Accident Sampling System (PASS).
The changes are consistent with Nuclear Regulatory Commission (NRC) approved Industry/Technical Specification Task Force (TSTF) Standard Technical Specification Change Traveler, TSTF-413. The availability of this TS improvement was announced in the Federal Register on March 20, 2002, as part of the consolidated line item improvement process (CLIIP).
2.0 ASSESSMENT 2.1 Applicability of Published Safety Evaluation Nebraska Public Power District (NPPD) has reviewed the safety evaluation published on December 27, 2001 (66 FR 66949), as part of the CLIIP. This verification included a review of the NRC staffs evaluation (as modified slightly by the notice of availability) as well as the supporting information provided to support TSTF-413 (i.e., NEDO-32991, "Regulatory Relaxation for BWR Post Accident Sampling Stations (PASS)," submitted November 30, 2000, and the associated NRC Safety Evaluation (SE) dated June 12, 2001).
NPPD has concluded that the justifications presented in the TSTF proposal and the SE, prepared by the NRC staff, are applicable to Cooper Nuclear Station (CNS) and justify this amendment for the incorporation of the changes to the CNS TS.
2.2 Optional Changes and Variations NPPD is not proposing any variations or deviations from the TS changes described in TSTF-413 or the NRC staffs model SE published on December 27, 2001.
Note 2 of the December 27, 2001 NRC SE identified three other potential TS changes for which the staff provided discussion. For CNS, applicability is as follows:
(1) Editorial changes No editorial changes to CNS TS are required to account for the changes covered in this request. The proposed TS reflect Subsection 5.5.3 as "Deleted." The remaining subsections in Section 5.5 are not renumbered.
NLS2014035 Attachment I Page 3 of 4 (2) Mention of PASS as a potential leakage source outside containment NPPD plans to leave PASS in place. Therefore, the configuration of PASS will continue to be a potential leakage path outside the Primary Containment for highly radioactive fluids. Any PASS leakage would be included in the cumulative allowed Emergency Core Cooling System leakage.
TS Subsection 5.5.2, Systems Integrity Monitoring Program, provides for a program to minimize leakage from those portions of systems outside containment that could contain highly radioactive fluids during a serious transient or accident. PASS is not mentioned in the scope of this program. Therefore, no revision to TS 5.5.2 is needed.
(3) TS Bases changes The elimination of PASS results in changes to the discussion in the TS Bases section B 3.3.6.1, Primary Containment Isolation Instrumentation. Item number 2.e, Reactor Vessel Water Level - Low Low Low (Level 1), discusses bypassing this function in order to obtain a sample for PASS. The specific mention of "PASS" is replaced with a reference to "core damage assessment capability." The proposed Bases revisions are provided in Attachment 4. NPPD will formally address the change to the TS Bases in accordance with the TS Bases Control Program of TS Section 5.5.10, and will provide the actual revised TS Bases pages in a future submittal required by 10 CFR 50.71(e).
No change to TS Bases B 3.3.3.1, Post Accident Monitoring (PAM) Instrumentation, is necessary since the current TS Bases do not mention PASS.
3.0 REGULATORY ANALYSIS
3.1 Applicable Regulatory Requirements/Criteria Construction of CNS predated the 1971 issuance of 10 CFR 50, Appendix A, "General Design Criteria for Nuclear Power Plants." Appendix F, "Conformance to AEC Proposed General Design Criteria," of the CNS Updated Safety Analysis Report discusses that CNS is designed to conform to the proposed general design criteria (GDC) published in the July 11, 1967, Federal Register, except where commitments were made to specific 1971 GDC. It notes that the Atomic Energy Commission (AEC) accepted CNS conformance with these proposed GDC.
This difference does not alter the conclusion that the proposed change is applicable to CNS.
NLS2014035 Attachment I Page 4 of 4 3.2 No Significant Hazards Consideration Nebraska Public Power District (NPPD) has reviewed the proposed no significant hazards consideration determination published on December 27, 2001 (66 FR 66949), as part of the consolidated line item improvement process. NPPD has concluded that the proposed determination presented in the notice is applicable to Cooper Nuclear Station and the determination is hereby incorporated by reference to satisfy the requirements of 10 CFR 50.91(a).
3.3 Verification and Commitments As discussed in the model SE published in Federal Register (FR) on December 27, 2001, for this TS improvement, plant-specific verifications were performed as follows:
- 1. NPPD verified it has contingency plans for obtaining and analyzing highly radioactive samples from the reactor coolant system, suppression pool, and containment atmosphere. NPPD will maintain this capability in CNS Chemistry Department procedures. Implementation of this commitment is complete.
- 2. NPPD verified it has established the capability for classifying fuel damage events at the Alert level threshold for CNS at radioactivity levels of 300 ACi/cc dose equivalent iodine. This capability is described in the Emergency Plan Implementing Procedure for performing dose projection. Implementation of this commitment is complete.
- 3. NPPD verified that it has an l-131 site survey detection capability, including an ability to assess radioactive iodines released to offsite environs, by using effluent monitoring systems or portable sampling equipment. The capability for monitoring iodines will be maintained in the Emergency Plan Implementing Procedures for manually determining airborne release rates and for onsite and offsite boundary monitoring. Implementation of this commitment is complete.
4.0 ENVIRONMENTAL EVALUATION NPPD has reviewed the environmental evaluation included in the model safety evaluation published on December 27, 2001 (66 FR 66949), as part of the CLIIP. NPPD has concluded that the NRC staff s findings presented in that evaluation are applicable to CNS and the evaluation is hereby incorporated by reference for this application.

Primary Containment Isolation Instrumentation B 3.3.6.1 BASES APPLICABLE SAFETY ANALYSES, LCO, and APPLICABILITY (continued) be OPERABLE to ensure that no single instrument failure can preclude the isolation function.
The Reactor Vessel Water Level-Low Low Low (Level 1) Allowable Value is chosen to be the same as the ECCS Level 1 Allowable Value (LCO 3.3.5.1) to ensure that the recirculation sample valves will isolate on a potential LOCA to prevent offsite doses from exceeding 10 CFR 50.67 limits.
This Function isolates the recirculation sample valves. It may be bypassed using a key-locked switch during accident conditions to obtain a sa~mpllef -tAofdn mpigSse(PS.
High Pressure Coolant Iniection and Reactor Core Isolation Cooling d
coedamage core eSystems Isolation assessment capability 3.a., 3.b., 4.a., 4.b. HPCI and RCIC Steam Line Flow-High and Time Delay Relays Steam Line Flow-High Functions are provided to detect a break of the RCIC or HPCI steam lines and initiate closure of the steam line isolation valves of the appropriate system. If the steam is allowed to continue flowing out of the break, the reactor will depressurize and the core can uncover. Therefore, the isolations are initiated on high flow to prevent or minimize core damage. The isolation action, along with the scram function of the RPS, ensures that the fuel peak cladding temperature remains below the limits of 10 CFR 50.46. Specific credit for these Functions is not assumed in any USAR accident analyses since the bounding analysis is performed for large breaks such as recirculation and MSL breaks. However, these instruments prevent the RCIC or HPCI steam line breaks from becoming bounding.
The HPCI and RCIC Steam Line Flow-High signals are initiated from differential pressure switches (two for HPCI and two for RCIC) that are connected to the system steam lines. A time delay is provided to prevent HPCI or RCIC isolation due to high flow transients during HPCI or RCIC startup with one Time Delay Relay channel associated with each Steam Line Flow-High channel. Two channels of both HPCI and RCIC Steam Line Flow-High Functions and the associated Time Delay Relays are available and are required to be OPERABLE to ensure that no single instrument failure can preclude the isolation function.
