Mr. G. Interim President and CEO/CNO STP Nuclear Operating Company P.O. Box 289 Wadsworth, TX 77483

SUBJECT: ANNUAL ASSESSMENT LETTER FOR SOUTH TEXAS PROJECT ELECTRIC GENERATING STATION UNITS 1 AND 2 (REPORT 05000498/2017006 AND 05000499/2017006)

Dear Mr. Powell:

The U.S. Nuclear Regulatory Commission (NRC) has completed its end-of-cycle performance assessment of South Texas Project Electric Generating Station, Units 1 and 2, reviewing performance indicators (PIs), inspection results, and enforcement actions from January 1, 2017 through December 31, 2017. This letter informs you of the NRC's assessment of your facility during this period and its plans for future inspections at your facility. The NRC concluded that overall performance at your facility preserved public health and safety. The NRC determined the performance at South Texas Project Electric Generating Station, Units 1 and 2, during the most recent quarter was within the Licensee Response Column, the highest performance category of the NRC's Reactor Oversight Process (ROP) Action Matrix, because all inspection findings had very low safety significance (i.e., Green), and all PIs were within the expected range (i.e., Green). As noted in NRC Inspection Report 05000498/2016407 and 05000499/2016407 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML17040A341), dated January 10, 2017, one Greater than Green violation in the Security Cornerstone was identified by the NRC during this assessment period. In its final significance determination letter for this violation, NRC Inspection Report 05000498/2017405 and 05000499/2017405 (ADAMS Accession No. ML17010A211), dated February 9, 2017, the NRC assessed the performance of the South Texas Project Electric Generating Station, Units 1 and 2, facility as within the Regulatory Response Column of the NRC's action matrix beginning in the fourth quarter of 2016. The NRC conducted a supplemental inspection pursuant to Inspection Procedure 95001, "Supplemental Inspection Response to Action Matrix Column 2 Inputs." As previously noted in supplemental inspection report 05000498/2017409; 05000499/2017409 and follow up assessment letter, dated September 27, 2017 (ADAMS Accession No. ML17270A267) the NRC concluded the station's actions met the objectives of Inspection Procedure 95001. As such, in accordance with the guidance in Inspection Manual Chapter 0305, "Operating Reactor Assessment Program," the White finding was closed, effective September 27, 2017. As a G. result, the NRC determined the performance at South Texas Project Electric Generating Station, Units 1 and 2, to be in the Licensee Response Column of the ROP Action Matrix as of October 1, 2017. Therefore, the NRC plans to also conduct ROP baseline inspections for your facility in 2018. The enclosed inspection plan lists the inspections scheduled through December 31, 2019. This updated inspection plan now includes planned security inspections which were formerly transmitted under separate correspondence. The NRC provides the inspection plan to allow for the resolution of any scheduling conflicts and personnel availability issues. Routine inspections performed by resident inspectors are not included in the inspection plan. The inspections listed during the last twelve months of the inspection plan are tentative and may be revised. The NRC will contact you as soon as possible to discuss changes to the inspection plan should circumstances warrant any changes. Additionally, to verify the adequacy of the security controls for a new independent spent fuel storage installation, the NRC will also conduct Inspection Procedure IP 81311, "Physical Security Requirements for Independent Spent Fuel Storage Installations," prior to the first loading of spent fuel. The NRC will use the advance notification required under § 72.212 (b)(1) to coordinate our initial inspection of this facility. In accordance with Title 10 of the Code of Federal Regulations (10 CFR) 2.390 of the NRC's "Rules of Practice," a copy of this letter will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of the NRC's document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room). Please contact Nicholas Taylor at (817) 200-1141 with any questions you have regarding this letter.

Sincerely,/RA/ Troy W. Pruett, Director Division of Reactor Projects Docket Nos. 50-498 and 50-499 License Nos. NPF-76 and NPF-80
