SUBJECT:
ANNUAL ASSESSMENT LETTER FOR BYRON STATION, UNITS 1 AND 2 (REPORT 05000454/2017006 AND 05000455/2017006)
Dear Mr. Hanson:
The NRC has completed its end-of-cycle performance assessment of Byron 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 NRCs 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 Byron Station, Units 1 and 2 during the most recent quarter was within the Licensee Response Column of the NRCs 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). Therefore, the NRC plans to conduct ROP baseline inspections at your facility.
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 12 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.
Temporary Instruction 194, Inspection of the Licensee's Implementation of Industry Initiative Associated With the Open Phase Condition Design Vulnerabilities In Electric Power Systems (NRC Bulletin 2012-01), is planned to start the week of April 2, 2018. This letter and its enclosure will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in accordance with 10 CFR 2.390, Public Inspections, Exemptions, Requests for Withholding.
Please contact Eric Duncan at 630-829-9620 with any questions you have regarding this letter.
Sincerely,
/RA/
Eric R. Duncan, Chief Branch 3 Division of Reactor Projects
