1.0 INTRODUCTION
By application dated February 4, 2016 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML16035A227), Exelon Generation Company, LLC (the licensee) requested an amendment to the licenses for Calvert Cliffs Nuclear Power Plant (CCNPP), Unit Nos. 1 and 2, DPR-53 and DPR-69, to revise the technical specifications (TSs) to change surveillance requirement (SR) 3.5.3.1.
The proposed change would include SR 3.5.2.10 in the list of applicable SRs shown in SR 3.5.3.1. This SR is applicable to the U.S. Nuclear Regulatory Commission (NRC)-approved Technical Specifications Task Force (TSTF) Standard Technical Specifications (STS) Change Traveler TSTF-523, Revision 2, "Generic Letter [GL] 2008-01, Managing Gas Accumulation,"
(ADAMS Accession No. ML13053A075) dated February 21, 2013. The NRC issued Amendment Nos. 313 and 291 dated July 30, 2015 (ADAMS Accession No. ML15161A380) which approved the implementation of TSTF-523 for CCNPP, Unit Nos. 1 and 2, respectively.
Subsequent to the issuance of these amendments, the licensee identified that inclusion of SR 3.5.2.10 should have also resulted in a change to SR 3.5.3.1.
2.0 REGULATORY EVALUATION
2.1 Regulatory Requirements The regulatory requirements and guidance documents which the NRC staff used in the review of the application are listed below:
- In Section 50.36 of Title 10 of the Code of Federal Regulations (10 CFR), the NRC established its regulatory requirements related to the content of TSs. Pursuant to 10 Enclosure 3
CFR 50.36, TSs are required to include items in the following five specific categories related to station operation: (1) Safety limits, limiting safety system settings, and limiting control settings; (2) Limiting conditions for operation (LCO); (3) Surveillance requirements; (4) Design features; and (5) Administrative controls.
2.2 Regulatory Guidance
- The NRC's guidance for the format and content of licensee TSs can be found in NUREG-1432, "Standard Technical Specifications, Combustion Engineering Plants,"
Revision 4.0, April 2012 (ADAMS Accession Nos. ML12102A165 and ML12102A169).
- The model SE for plant-specific adoption of TSTF STS Change Traveler TSTF-523, Revision 2 "Generic Letter 2008-01, Managing Gas Accumulation," dated December 23, 2013, can be found in ADAMS Accession No. ML13255A169. The availability of this TS improvement was announced in the Federal Register on January 15, 2014 (79 FR 2700).
3.0 TECHNICAL EVALUATION
3.1 Background By letter dated July 30, 2015, the NRC issued license amendments that revised the CCNPP TSs by implementing TSTF-523. These amendments added new SRs related to gas accumulation for the shutdown cooling system, the emergency core cooling system (ECCS),
and the containment spray system to the CCNPP TSs. Specifically, SR 3.5.2.10 was added to the CCNPP TSs because there was not an existing SR related to gas accumulation. The licensee did not identify, and subsequently did not request a change to the TSs, that adding the new SR 3.5.2.10 should have resulted in a change to SR 3.5.3.1 as well.
The licensee has implemented administrative controls as per Administrative Letter 98-10 "Dispositioning of Technical Specifications that are Insufficient to Assure Plant Safety," dated December 29, 1998, to include SR 3.5.2.1 O into the list of applicable SRs shown in SR 3.5.3.1 while the NRC evaluates this LAR.
3.2 Licensee's Proposed Changes In its LAR dated February 4, 2016, the licensee proposed to add SR 3.5.2.10 to the list of applicable SRs shown in SR 3.5.3.1.
3.3 NRC Staff Evaluation As noted in the discussion above, the licensee previously received license amendments that incorporated the SRs listed in TSTF-523 into the CCNPP TSs. The staff's review of the amendments established that addition of the SRs in TSTF-523 met the regulatory requirements of 10 CFR 50.36 because the changes provided assurance that the necessary quality of
systems and components will be maintained and that the LCO will be met, and therefore, were acceptable to the staff.
Specifically, TSTF-523 modified CCNPP LCO 3.5.2, "ECCS - Operating," by adding an SR.
The new SR requires that ECCS locations susceptible to gas accumulations be verified [to be]
sufficiently filled with water.
Prior to receiving approval of the TSTF-523 amendment, the CCNPP TSs did not contain a SR requiring the licensee's verification that ECCS locations susceptible to gas accumulation be sufficiently filled with water. The Combustion Engineering (CE) STS contains an existing SR (SR 3.5.2.3) to verify that the ECCS piping is full of water. In the CE STS, this SR is included in the list of applicable SRs in SR 3.5.3.1. When the model SE for TSTF-523 was developed it was based, in part, on the CE STS. Therefore, TSTF-523 didn't explicitly require the modification of the list of applicable SRs in SR 3.5.3.1 to add the SR to verify ECCS piping is full of water. As stated in its application, the licensee failed to identify that the addition of a new SR should result in a change to SR 3.5.3.1 to capture the new SR.
The NRC staff has reviewed the proposed change and determined that the existing SR 3.5.2.10 in the CCNPP TSs should have been included as one of the applicable SRs listed in SR 3.5.3.1.
The staff has determined that this change is acceptable as it had previously approved the implementation of TSTF-523 into the CCNPP TSs which covers the licensee's proposed change.
3.4 Technical Evaluation Conclusions The NRC staff has found that the change described above is consistent with TSTF-523 and satisfies the requirements for TSs in 10 CFR 50.36. Therefore, the NRC staff has concluded that the change to SR 3.5.3.1 as described above is acceptable.
4.0 STATE CONSULTATION
In accordance with the Commission's regulations, the Maryland State official was notified of the proposed issuance of the amendments. The State official had no comments.
5.0 ENVIRONMENTAL CONSIDERATION
The amendments change a requirement with respect to the installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 and changes SRs.
The NRC staff has determined that the amendments involve no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendments involve no significant hazards consideration, and there has been no public comment on such finding published in the FR on May 24, 2016 (81 FR 32806). Accordingly, the amendments meet 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 amendments.
6.0 CONCLUSION
The Commission has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) there is reasonable assurance that such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendments will not be inimical to the common defense and security or to the health and safety of the public.
