SUMMARY
DESCRIPTION Pursuant to 10 CFR 50.90, Indiana Michigan Power Company (l&M), the licensee for Donald C. Cook Nuclear Plant (CNP) Unit 1 and Unit 2, proposes to amend the Appendix A Technical Specifications (TS) to Facility Operating Licenses DPR-58 and DPR-74. l&M proposes to change TS 5.5.14, Containment Leakage Rate Testing Program, to clarify the containment leak rate testing pressure criteria.
2.0 DETAILED DESCRIPTION TS 5.5.14 b. currently states, "The calculated peak containment internal pressure for the design basis loss of coolant accident, Pa, is 12 psig." l&M proposes to change this statement to read, "The containment design pressure is 12 psig. For the. containment Leakage Rate Testing Program, Pa is defined as 12.0 psig."
Enclosures 3 and 4 to this letter provide the Unit 1 and Unit 2 TS pages, respectively, marked to show proposed changes. New text on these pages is marked with a single-line border. New clean Unit 1 and Unit 2 TS pages with proposed changes incorporated will be provided to the Nuclear Regulatory Commission (NRC) Licensing Project Manager when requested.
3.0 TECHNICAL EVALUATION
3.1 Background By letter dated April 6, 2004 (Reference 2), l&M requested to convert from Current TS (CTS) to Improved TS (ITS). Amendment 287 for Unit 1 and Amendment 269 for Unit 2 were issued June 1, 2005. The calculated peak containment pressure values have historically been relatively close to the design pressure value. Recent containment integrity re-analyses using new analysis methods have resulted in reduced calculated peak containment pres~ures. l&M's conversion from CTS to ITS combined with the new containment integrity analyses have resulted in confusion regarding the language in TS 5.5.14. The language is not specific in describing the 12 psig value as the Pa value for containment leak rate testing purposes. The 12 psig value was previously established in the licensing basis as the test value and is not the same as the calculated peak containment pressure.
The containment design pressure is 12 psig for both CNP units. Current calculated peak pressure from a loss-of-coolant accident (LOCA) is 10.37 psig for Unit 1 and 10. 78 psig for .Unit
- 2. The Updated Final Safety Analysis Report (UFSAR), Section 5.7.3, states that periodic leak rate testing is performed at the design pressure of 12 psig. The UFSAR testing criteria has remained consistent since the initial issue of the FSAR.
NEI 94-01, Revision 3-A, "Industry Guideline for Implementing Performance-Based Option of 10 CFR Part 50, Appendix J" endorses American National Standard ANSl/ANS-56.8-2002, "Containment System Leakage Testing Requirements" for testing details. NEI 94-01, Revision 3-A, Section 8, "Testing Methodologies for Type A, Band C Tests" states that Type A, Type B and Type C tests should be performed using the technical methods and techniques specified in ANSl/ANS-56.8-2002. Section 3.3.2, Test Pressure, of this ANSI Standard states:
Enclosure 2 to AEP-NRC-2016-64 Page 3 "Type B and C tests shall be conducted at a differential pressure of greater than or equal to Pa unless otherwise specified in the plant's licensing basis. When a higher differential pressure results in increased sealing, the differential pressure shall not exceed 1.1 Pa"*
3.2 Evaluation CNP desires to clarify that Pa is defined as 12.0 psig for the Containment Leakage Rate Testing Program. The definition for the term Pa in ANSl/ANS-56.8-2002 and 10 CFR Part 50 Appendix J .is the peak containment internal pressure related to the design basis LOCA. Containment design pressure, Pd, has remained at 12.0 psig for both CNP units. Containment leakage rate testing has also consistently been conducted using a value of Pa equal to 12.0 psig, as defined in the CNP licensing basis. Maximum* peak containment internal pressure related to LOCA event Pa, has been revised three times at CNP for the values of 11.85 psig, 11.75 psig, and 11.43 psig for both units (using a single bounding analysis for both units). For the majority of CNP's operation, the calculated LOCA pressure has been relatively close to the licensing basis value of 12 psig. A recent LOCA reanalysis resulted in calculated peak pressures of 10.37 psig
- for Unit 1 and 10.78 psig for Unit 2. This reanalysis was implemented under a 10 CFR 50.59 review and uses the methodology in WCAP-17721-P-A (Reference 4) which was approved for use by the NRC in Reference 5. Note that the reduced calculated LOCA pressure is due to a new analysis method and does not correspond to plant modifications that would impact the actual response during a design basis event. As a comparative reference point, using the current calculated peak pressure, the difference in test pressure for local leak rate test (LLRT) is approximately 1.63 psig for Unit 1 and 1.22 psig for Unit 2. Using a Pa of calculated peak pressure would result in test pressures slightly lower than the licensing basis value Pa of 12 psig for CNP. Therefore, CNP's licensing basis value of 12 psig for containment leakage rate testing program is acceptable.
As discussed, the NEI 94-01, Revision 3-A, guidance for Appendix J limits the differential pressure used during testing to 1.1 Pa. The purpose of this guidance is to prevent testing to be performed at significantly higher pressures than those expected to be observed during a design basis LOCA event. For example, when compared to CNP's 12 psig containment design pressure, testing a check valve at 55 psig would cause the check valve to seat tighter and therefore leak less. This limitation would not be a concern for a large majority of components tested under the Containment Leakage Rate Testing Program, which would have conservative results at higher pressures.
Use of Pa at 12 psig for the Containment Leakage Rate Testing Program will not result in a significantly larger differential pressure to seal components whose characteristics result in improved sealing based on increased pressure. This allowance also results in having consistent LLRT pressures for each unit.
4.0 REGULATORY EVALUATION
4.1 Applicable Regulatory Requirements/Criteria Title 10 Code of Federal Regulations (CFR) 50.36, "Technical specifications" states:
(c) Technical specifications will include items in the following categories:
to AEP-NRC-2016-64 Page4
- 4) Design features. Design features to be included are those features of the facility such as materials of construction and geometric arrangements, which, if altered or modified, would have a significant effect on safety and are not covered in categories described in paragraphs (c) (1 ), (2), and (3) of this section.
The proposed change will modify TS 5.5.14 b., for the Containment Leakage Rate Testing Program. This change does not modify the testing requirements for Leak Rate Testing.
Therefore, the requirements of Title 10 CFR 50.36 continue to be met with the changes proposed in this license amendment request for TS 5.5.14 b.
General Design Criteria The construction permits for CNP were issued and the majority of construction was completed prior to issuance of 10 CFR 50, Appendix A, General Design Criteria, in 1971 by the Atomic Energy Commission (AEC). CNP was designed and constructed to comply with the AEC General Design Criteria (GDC) as proposed on July 10, 1967. The application of the AEC proposed General Design Criteria to the CNP is contained in the CNP UFSAR as the Plant Specific Design Criteria (PSDC). Appendix A of 10 CFR Part 50 GDC differs both in numbering and content from the PSDC for CNP.
The impact of the Surveillance Requirment changes proposed in this submittal on the PSDC applicable to this license amendment request are discussed below:
PSDC 54 Initial Leak Rate Testing for Containment The CNP UFSAR states:
"The containment shall be designed so that integrated leakage rate testing can be conducted at the peak pressure calculated to result from the design basis accident after
- completion and installation of all penetrations and the leakage rate shall be measured over a sufficient period of time to verify its conformance with required performance.
The containment was designed so that its maximum integrated leakage under accident conditions meets the site exposure criteria set forth in 10 CFR 100 guidelines. "
PSDC 55 Periodic Containment Leakage Rate Testing The CNP UFSAR states:
"The containment shall be designed so that an integrated leakage rate can be periodically determined by tests during the plant lifetime.
The containment is designed to permit full-integrated leak rate tests."
to AEP-NRC-2016-64 Page 5 With the changes proposed in this license amendment request, the requirements of PSDC 54 and 55 continue to be met and the plant TS will continue to provide the basis for safe plant operation.
4.2 Precedent By letter dated September 30, 2015, the NRC issued amendments to Sequoyah Nuclear Plant, Units 1 and 2 for the Conversion to the Improved Technical Specifications with beyond Scope Issues. This amendment approved the use of wording for the Containment Leakage Rate Testing Program which is consistent with the proposed wording in .this License Amendment Request (LAR).
4.3 No Significant Hazards Consideration Determination Pursuant to 10 CFR 50.90, l&M, the licensee for CNP Unit 1 and Unit 2, proposes to amend the Appendix A TS to Facility Operating Licenses DPR-58 and DPR-74. l&M proposes a change to TS 5.5.14, Containment Leakage Rate Testing Program, to clarify the calculated peak containment internal pressure related to the design basis accident. l&M has evaluated whether a significant hazards consideration is involved with the proposed amendment by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of amendment," as discussed below:
- 1. Does the proposed change involve a significant increase in the probability of occurrence or consequences of an accident previously evaluated?
Response: No The proposed changes do not involve changes to the installed structures, systems or components of the facility. The proposed change is consistent with Westinghouse Owners Group Standard Technical Specification language for the Containment Leak Rate Program.
Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 2. Does the proposed change create the possibility of a new or different kind of accident from any accident previously evaluated?
Response: No The proposed change does not introduce a new mode of plant operation and does not involve physical modification to the plant. The change does not introduce new accident initiators or impact assumptions made in the safety analysis. Testing requirements continue to demonstrate that the Limiting Conditions for Operation are met and the system components are functional.
Therefore, the proposed change does not create the possibility of a new or different kind of accident from any previously evaluated.
Enclosure 2 to AEP-NRC-2016-64 Page 6
- 3. Does the proposed change involve a significant reduction in a margin of safety?
Response: No The proposed change does not exceed or alter a design basis or safety limit, so there is no significant reduction in the margin of safety.
Therefore, the proposed change does not involve a significant reduction in a margin of safety.
Based on the above, l&M concludes that the proposed amendment presents no significant hazards consideration under the standards set forth in 10 CFR 50.92(c), and, accordingly, a finding of "no significant hazards consideration" is justified.
4.4 Conclusion In conclusion, based on the considerations discussed above, (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed
. manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
5.0 ENVIRONMENTAL CONSIDERATION
l&M has evaluated this LAR against the criteria for identification of licensing and regulatory actions requiring environmental assessment in accordance with 10 CFR 51.21. l&M ha~
determined that this LAR meets the criteria for a categorical exclusion set forth in 10 CFR 51.22( c)(9). This determination is based on the fact that this change is being proposed as an amendment to a license issued pursuant to 10 CFR Part 50 that changes a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR Part 20, or that changes an inspection or a surveillance requirement, and the amendment meets the following specific criteria:
(i) . The amendment involves no significant hazards consideration.
As demonstrated in Section 4.3, the proposed TS change does not involve a significant hazards consideration.
(ii) There is no significant change in the types or significant i"ncrease in the amounts of any effluent that may be released offsite.
- This LAR will not change the types or amounts of any effluents that may be released offsite.
(iii) There is no significant increase in individual or cumulative occupational radiation exposure.
This LAR will not increase the individual or cumulative occupational radiation exposure.
