| ==1.0 INTRODUCTION==
| |
| | |
| By {{letter dated|date=July 30, 2020|text=letter dated July 30, 2020}} (Agencywide Documents Access and Management System (ADAMS) Accession No. ML20212L521), as supplemented by {{letter dated|date=September 22, 2020|text=letter dated September 22, 2020}} (ADAMS Accession No. ML20266H819), STP Nuclear Operating Company (the licensee) submitted a license amendment request to the U.S. Nuclear Regulatory Commission (NRC, the Commission) for the South Texas Project, Units 1 and 2 (STP).
| |
| The proposed changes would revise TS 6.8.3.i, Diesel Fuel Oil Testing Program, by relocating references to specific American Society for Testing and Materials (ASTM) standards for fuel oil testing to the Technical Specifications (TS) Bases and adding alternate criteria to the clear and bright acceptance test for new fuel oil. The changes are based upon Technical Specifications Task Force (TSTF) Traveler TSTF-374, Revision to TS 5.5.13 and Associated TS Bases for Diesel Fuel Oil. These changes were described in a Notice of Availability published in the Federal Register on April 21, 2006 (71 FR 20735) (ADAMS Accession No. ML061040356).

| | |
| ==2.0 REGULATORY EVALUATION==
| |
| | |
| The onsite electrical power system includes standby power sources, distribution systems, and vital auxiliary supporting systems to supply power to safety-related equipment. Most commercial nuclear power plants use diesel generators as the emergency power source for the safety-related electrical buses. The importance of the diesel generators (or other standby power sources), is reflected in their incorporation into NRC regulations, TS, and other regulatory programs, including Appendix B, Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants, to Part 50 of Title 10 of the Code of Federal Regulations (10 CFR Part 50). NUREG-0800, Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR [Light-Water Reactor] Edition, addresses diesel fuel oil and other supporting systems in Section 9.5.4, Emergency Diesel Engine Fuel Oil Storage and Transfer System Review Responsibilities.
| |
| Enclosure 3
| |
| | |
| The TS includes requirements for testing diesel fuel oil to ensure it is of the appropriate grade and that it has not been contaminated (i.e., proper fuel oil quality). The Diesel Fuel Oil Testing Program defined in the TS includes tests for (1) the acceptability of new fuel oil for use prior to addition to storage tanks; (2) other properties of new fuel oil within limits within 31 days following sampling and addition to storage tanks; and (3) total particulate concentration of the fuel oil every 31 days. The current TS identify particular ASTM standards and methods of performing these tests. The industry submitted TSTF-374 proposing changes to the Standard TS (STS)
| |
| (NUREGs 1430-1434) to provide the flexibility to address future changes in Environmental Protection Agency (EPA) regulations for fuel oil or revisions to the ASTM standards. TSTF-374 was reviewed and accepted by the NRC staff and has been incorporated into each of the STS NUREGs. Requirements for testing the diesel fuel oil are maintained, but references to specific ASTM standards are relocated to licensee-controlled documents and an alternative to the clear and bright acceptance test for new fuel is added to address changes in EPA requirements.
| |
| | |
| ==3.0 TECHNICAL EVALUATION==
| |
| | |
| In adopting TSTF-374, the licensee proposes to relocate the reference to specific ASTM standards from the TS Administrative Controls Section 6.8.3.i to a licensee-controlled document. Although the reference to specific testing standards or methods is relocated, TS 6.8.3.i retains acceptance criteria for new and stored diesel fuel oil and refers to applicable ASTM standards for sampling and testing requirements. The specific testing standards or methods are relocated to the TS Bases Section, which are controlled in accordance with 10 CFR 50.59, Changes, tests, and experiments, as described in TS 6.8.3.m, Technical Specification (TS) Bases Control Program. The licensee's testing programs for diesel fuel oil are also governed by other regulatory requirements, including Appendix B (Quality Assurance Criteria) to 10 CFR Part 50. While the relocation of selected program details provides the licensee with some flexibility to adopt practices defined in future ASTM standards, the NRC staff finds that the remaining TS, TS Bases Control Program, and other NRC regulations provide appropriate regulatory controls to ensure diesel fuel oil quality will be maintained.
| |
| The plant-specific adoption of TSTF-374 also includes an alternative to the clear and bright test currently required for new fuel oil acceptability. The revised TS would allow either the clear and bright test or a test confirming that the fuel oil has water and sediment content within limits. This alternative test is better suited for darker colored fuels and is recognized in ASTM standards that have been referenced in NRC approved amendment requests. The NRC staff finds that the alternative for testing the water and sediment content will maintain or improve the inspection of new fuel oil and therefore finds the change acceptable.
| |
| The licensee included in its application the proposed revisions to the TS Bases to reflect the changes to TS 6.8.3.i and to incorporate the references to the applicable ASTM standards. In the above Notice of Availability, the NRC requested TS Bases changes be included with the proposed license amendments consistent with the Bases in TSTF-374. The STP TS and Bases are custom specifications. As a result, the current STP Bases were not consistent with the STS Bases and the markup to the STS Bases provided in TSTF-374. Therefore, the licensee proposed conforming changes to the STP Bases to ensure consistency with the STS Bases used to develop TSTF-374 and changes to STS Bases as provided in TSTF-374. The proposed STP Bases change also include updated references to applicable ASTM standards, as the applicable ASTM standards associated with testing diesel fuel have changed since the NRC approved TSTF-374 in 2005.
| |
| | |
| In addition, the STS Bases used to develop TSTF-374 changes described American Petroleum Institute (API) gravity fuel limits. However, the current STP Bases, due to their custom nature, did not describe API gravity fuel limits. Rather, STPs Diesel Fuel Oil Testing Program, a licensee-controlled program, defined STPs API gravity fuel limits. The proposed STP Bases include API gravity limits to ensure consistency with the STS Bases used to develop TSTF-374 and STPs Diesel Fuel Oil Testing Program. However, STPs API gravity range described in STPs current Diesel Fuel Oil Testing Program and STPs proposed revision to STP Bases differ slightly from the STS Bases used to develop TSTF-374. The API gravity range in STPs Diesel Fuel Oil Testing Program was previously adjusted (i.e., not as part of this license amendment request) in order to accommodate higher API gravity fuels that STP expected to receive from fuel vendors. As described in the license amendment request as supplemented, STP performed an evaluation that approved use of a higher API gravity limit (i.e., 42°) in comparison to the STS Bases used to develop TSTF-374. STP applied the 10 CFR 50.59 process to this API gravity change and determined that NRC approval was not required prior to making the change to STPs licensee-controlled Diesel Fuel Oil Testing Program. The STP Bases changes are consistent with TSTF-374 (considering updates to applicable ASTM standards and the use of the 10 CFR 50.59 process) and will be incorporated into the TS Bases in accordance with TS 6.8.3.m.
| |
| | |
| ==4.0 STATE CONSULTATION==
| |
| | |
| In accordance with the Commissions regulations, the Texas State official was notified of the proposed issuance of the amendments on March 15, 2021. The State official had no comments.
| |
| | |
| ==5.0 ENVIRONMENTAL CONSIDERATION==
| |
| | |
| The amendments change requirements with respect to installation or use of facility components located within the restricted area as defined in 10 CFR Part 20 and change surveillance requirements. 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, as published in the Federal Register on November 3, 2020 (85 FR 69656), and there has been no public comment on such finding.
| |
| 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 Commissions 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.
