OTHER ACTIVITIES

- TEMPORARY INSTRUCTIONS, INFREQUENT AND ABNORMAL 71003 - Post-Approval Site Inspection for License Renewal The inspection was conducted as outlined in NRC Inspection Procedure 71003, Phase 2 - Post-Approval Site Inspection for License Renewal, as a supplement to the Phase 2 team inspection completed at Salem Unit 1 (IR 05000272/2015011). This inspection effort included walkdowns of selected SSCs subject to aging management programs; interviews with engineers, and reviews of associated design and licensing documents to evaluate if PSEG was meeting their License Renewal commitments and to verify inspections or examinations required to be performed had been and would be completed prior to the period of extended operations. For the aging management programs selected, the inspector reviewed the parameters monitored or inspected, detection of aging effects, and acceptance criteria for program procedures. Documents reviewed for this inspection are listed in the Attachment.

The Aging Management Programs (AMPS) reviewed were:

Post-Approval Site Inspection for License Renewal ===

(1) Thermal Aging Embrittlement of Cast Austenitic Stainless Steel (CASS)

(2) One-Time Inspection

(3) One-Time Inspection of (ASME) Code Class 1 Small-Bore Piping

(4) Electrical Cables and Connections Not Subject to 10 CFR 50.49 Equipment Qualification Requirements

(5) Metal Enclosed Bus

(6) Periodic Inspections

INSPECTION RESULTS

Licensee-Identified Non-Cited Violation 71152 This violation of very low safety significance was identified by the licensee and has been entered into the licensee corrective action program and is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.

Violation: 10 CFR Part 50, Appendix B, Criterion III, Design Control, requires that measures shall provide for verifying or checking the adequacy of design, such as by the performance of design reviews, by the use of alternate or simplified calculational methods, or by the performance of a suitable testing program.

PSEG procedures CC-AA-103, Revision 15, Configuration Change Control for Permanent Physical Plant changes, Section 4.5.10, and CC-AA-102, Revision 25, Design Input and Configuration Change Impact Screening, Section 4.1.5, implement these requirements for verifying or checking the adequacy of design.

Contrary to the above, since the approval of the Design Change Package (DCP) in October 2014 until present for the Salem Unit 1 and 2 Chilled Water System chillers replacement, PSEG did not adequately verify and check the adequacy of the design via design reviews, an alternate or simplified calculational method, or a suitable testing program. The inspectors determined that this is a violation of 10 CFR Part 50, Appendix B, Criterion III.

PSEG has implemented adequate intermediate corrective actions until the permanent corrective actions are completed to resolve the low chill water flow condition.

This violation of very low significance was identified by PSEG and has been entered into their corrective action program and is being treated as a NCV, consistent with Section 2.3.2 of the Enforcement Policy.

Significance/Severity: Green. The inspectors reviewed NRC IMC 0609, Initial Characterization of Findings, Attachment 4, issued on October 7, 2016 and IMC 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, issued on June 19, 2012. The inspectors determined that the finding is of very low safety significance (Green) because under Exhibit 2, Mitigating Systems Screening Questions, of IMC 0609, Appendix A, the finding screens to Green for being a deficiency affecting the design or qualification of a mitigating system, structure, or component (SSC) while the SSC maintains its operability or functionality.

Corrective Action References: 70206648, 70207634 Observation: Follow-up of chiller issues and 13 chiller low chilled water flow 71152 condition The inspectors performed an in-depth review of PSEGs evaluations and corrective actions associated with multiple equipment issues experienced on the chillers and chill water systems for Units 1 and 2 since July 1, 2018. The inspectors reviewed associated documents and interviewed personnel to assess the adequacy of PSEG completed actions and planned follow-up actions.

Following the permanent plant modification replacing the 13 chiller with a newly designed chiller in March 2019, a low chilled water flow condition was identified during the modification acceptance testing (MAT). The inspectors reviewed PSEGs actions to resolve the low flow condition and the overall system impact this condition could have on the chill water systems ability to fulfill its safety function. PSEG completed an extensive design review and operability evaluation to ensure the systems capabilities during normal and accident conditions. Prior to the replacement of the other Unit 1 and Unit 2 chillers, PSEGs planned corrective actions include performing a chiller system flow re-balance, using throttle valves to maintain the re-balanced system flow, and additional system MAT.

The inspectors evaluated all of the chiller system issues in accordance with the guidance in IMC 0612, Appendix B, Issue Screening, and Appendix E, Examples of Minor Issues, and determined all but one of the issues were of minor significance because the inspectors did not identify any condition adverse to quality that were not appropriately corrected or scheduled for correction in a reasonable period of time. Consequently, these issues are not subject to enforcement action in accordance with the NRCs enforcement policy. However, inspectors documented one deficiency associated with design control of the chillers, specifically with PSEGs control of the design change process. This deficiency is documented above.
