Dear Mr. Hanson:

On May 19, 2017, the U.S. Nuclear Regulatory Commission (NRC) completed an Evaluations of changes, Tests, and Experiments inspection at your Byron Station. On June 29, 2017, the NRC issued Inspection Report 05000454/2017009; 05000455/2017009. This original inspection report documented one traditional enforcement Severity Level IV violation with an associated finding in which the NRC treated as a Non-Cited Violation (NCV) in accordance with Section 2.3.2 of the NRC Enforcement Policy. In a letter dated July 23, 2018, (ML18204A144) the NRC withdrew the NCV based on an independent panels review. The purpose of this letter is to re-issue the NRC Inspection Report 05000454/2017009; 05000455/2017009 in its entirety.

The inspection examined activities conducted under your license as they relate to safety and compliance with the Commissions rules and regulations and with the conditions of your license.

The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.

No findings or violations of more-than-minor significance were identified during this inspection. This letter, its enclosure, and your response (if any) 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.

Sincerely,

/RA/

Station, Units 1 and 2; Evaluations of Changes, Tests, and Experiments.

This report covers a one-week announced Evaluations of Changes, Tests, and Experiments baseline inspection. The inspection was conducted by Region III based engineering inspectors.

The NRCs program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 6, dated July 2016.

REPORT DETAILS

1R17 Evaluations of Changes, Tests, and Experiments

.1 Evaluation of Changes, Tests, and Experiments

a. Inspection Scope

The inspectors reviewed evaluations performed pursuant to Title 10 of the Code of Federal Regulations (CFR), Part 50, Section 59 to determine if the evaluations were adequate and that prior U.S. Nuclear Regulatory Commission (NRC) approval was obtained as appropriate. The inspectors also reviewed screenings and applicability determinations where licensee personnel had determined that a 10 CFR 50.59 evaluation was not necessary. The inspectors reviewed these documents to determine if:

• the changes, tests, and experiments performed were evaluated in accordance with 10 CFR 50.59 and that sufficient documentation existed to confirm that a license amendment was not required;

• the safety issue requiring the change, tests or experiment was resolved;

• the licensee conclusions for evaluations of changes, tests, and experiments were correct and consistent with 10 CFR 50.59; and

• the design and licensing basis documentation was updated to reflect the change.

The inspectors used, in part, Nuclear Energy Institute (NEI) 96-07, Guidelines for 10 CFR 50.59 Implementation, Revision 1, to determine acceptability of the completed evaluations and screenings. The NEI document was endorsed by the NRC in Regulatory Guide 1.187, Guidance for Implementation of 10 CFR 50.59, Changes, Tests, and Experiments, dated November 2000. The inspectors also consulted Part 9900 of the NRC Inspection Manual, 10 CFR Guidance for 10 CFR 50.59, Changes, Tests, and Experiments.

This inspection constituted 23 samples of evaluations, screenings, and/or applicability determinations as defined in IP 71111.17-05.

b. Findings

No findings or violations of significance were identified

4OA2 Problem Identification and Resolution

.1 Routine Review of Condition Reports

a. Inspection Scope

The inspectors reviewed several corrective action process documents that identified or were related to 10 CFR 50.59 evaluations. The inspectors reviewed these documents to evaluate the effectiveness of corrective actions related to evaluations of changes, tests, and experiments. In addition, corrective action documents written on issues identified during the inspection were reviewed to verify adequate problem identification and incorporation of the problems into the corrective action system. The specific corrective action documents that were sampled and reviewed by the inspectors are listed in the attachment to this report.

b. Findings

No findings of significance were identified.

4OA6 Meetings

.1 Exit Meeting Summary

On November 8, 2018, the inspection results were presented to Ms. Z. Cox. The licensee personnel acknowledged the inspection results presented and did not identify any proprietary content. The inspectors confirmed that all proprietary material reviewed during the inspection was returned to the licensee staff.

.2 Interim Exit Meetings

On June 1, 2017, the inspectors presented the original inspection results to Mr. T. Chalmers, and other members of the licensee staff. The inspectors confirmed that none of the potential report input discussed was considered proprietary.
