During 2016 and 2017, several examples of inadequate assessment and management of risk were identified, including an unplanned change to station risk that resulted in a Green non-cited violation (05000387/2017002-02), an inadvertent break of a daisy chained neutral while changing a light socket that resulted in single loop operations and a significant power transient, and an inadvertent electrical short during maintenance that resulted in a reactor scram.


Susquehanna performed a cause analysis on the events under CR-2017-17228. In all cases the cause was related to issues with human performance, communications, and not challenging assumptions. Corrective actions taken by Susquehanna included revision of the Emergent Work Checklist and the High Risk Challenge Board procedural guidance to include a requirement to consider the consequences prior to performing work. The station also revised procedure NDAP-QA-1902, Integrated Risk Management, to add a requirement for development of risk mitigation actions for a Yellow probabilistic risk assessment risk.

Susquehanna conducted a thorough technical review of their foreign material exclusion (FME)program under CR-2017-13888. Susquehanna determined that there was a lack of program ownership for the FME program combined with a lack of oversight by the line organizations in regards to FME controls. Corrective actions included assigning an FME coordinator to fill the vacant role at the station, assign individuals within each line organization to become the FME lead within that organization, and to reinstate monthly FME steering committee meetings.

Additionally, the inspectors reviewed CR-2017-11996 to evaluate and correct the A EDG not meeting starting time requirements.


The inspectors review of CR-2017-00530 determined that Susquehanna engineering staff concluded there was not an adverse trend because a review of records since January 2009 documented normal operating start times from 7 to 8.9 seconds. The review also determined Susquehanna staff were generating condition reports at a lower threshold which resulted in an increased number of condition reports. The inspectors concluded the evaluation was conducted with sufficient technical rigor to support the conclusions.

PLANT STATUS

Unit 1 began the inspection period at 100 percent power. On August 3, 2018, operators reduced power to approximately 57 percent to perform a rod sequence exchange. Full power was achieved again on August 5, 2018. On August 18, 2018, operators shut down the unit for a planned maintenance outage to replace a reactor recirculation pump seal. Following seal replacement, operators commenced a reactor startup on August 23, 2018, and commenced a ramp towards full power, achieving 96 percent power on August 30, 2018. On August 30, 2018, operators lowered power to 59 percent following an electrical disturbance that caused a loss of drywell cooling. Following restoration of drywell cooling, operators restored power to 96 percent and continued the ramp, achieving full power on the same day. Unit 1 remained at or near 100 percent power for the remainder of the inspection period.

Unit 2 began the inspection period at 100 percent power. On August 30, 2018, operators lowered power to 60 percent following an electrical disturbance that caused a loss of drywell cooling. Following restoration of drywell cooling, operators restored power to 100 percent that same day. On August 31, 2018, operators reduced power to approximately 62 percent to perform a rod pattern adjustment. Operators returned the unit to 100 percent on September 2, 2018, and remained at or near 100 percent power for the remainder of the inspection period.

INSPECTION SCOPES

Inspections were conducted using the appropriate portions of the inspection procedures (IPs) in effect at the beginning of the inspection unless otherwise noted. Currently approved IPs with their attached revision histories are located on the public website at http://www.nrc.gov/reading-rm/doc-collections/insp-manual/inspection-procedure/index.html. Samples were declared complete when the IP requirements most appropriate to the inspection activity were met consistent with Inspection Manual Chapter (IMC) 2515, Light-Water Reactor Inspection Program - Operations Phase. The inspectors performed plant status activities described in IMC 2515, Appendix D, Plant Status, and conducted routine reviews using IP 71152, Problem Identification and Resolution. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel to assess Susquehannas performance and compliance with Commission rules and regulations, license conditions, site procedures, and standards.

OTHER ACTIVITIES

- TEMPORARY INSTRUCTIONS, INFREQUENT, AND ABNORMAL

IP 92709 - Contingency Plans for Licensee Strikes or Lockouts

Susquehanna developed a Business Continuity Plan to ensure a sufficient number of qualified personnel were available to continue operations in the event that Local 1600 International Brotherhood of Electrical Workers (IBEW) personal engaged in a job action upon the expiration of their contract on August 26, 2018. Using guidance contained in NRC IP 92709, Contingency Plants for Licensee Strikes or Lockouts, the inspectors reviewed Susquehannas plans to address a potential job action at the site. On August 24, 2018, Susquehanna and IBEW, Local 1600, tentatively agreed to a new contract and union members subsequently approved the new contract. No job action was taken.

INSPECTION RESULTS

Observations 71152 Annual Follow-up of Selected Issues Condition Report CR-2017-17228, Cognitive trend of not effectively utilizing risk mitigation actions during emergent work

During 2016 and 2017, several examples of inadequate assessment and management of risk were identified, including an unplanned change to station risk that resulted in a Green non-cited violation (05000387/2017002-02), an inadvertent break of a daisy chained neutral while changing a light socket that resulted in single loop operations and a significant power transient, and an inadvertent electrical short during maintenance that resulted in a reactor scram.

Susquehanna performed a cause analysis on the events under CR-2017-17228. In all cases the cause was related to issues with human performance, communications, and not challenging assumptions. Corrective actions taken by Susquehanna included revision of the Emergent Work Checklist and the High Risk Challenge Board procedural guidance to include a requirement to consider the consequences prior to performing work. The station also revised procedure NDAP-QA-1902, Integrated Risk Management, to add a requirement for development of risk mitigation actions for a Yellow probabilistic risk assessment risk.

The inspectors reviewed the technical adequacy and depth of evaluations performed by the licensee for these issues. The inspectors also evaluated the licensees development and implementation of corrective actions in this area and concluded that they were reasonable.

Observations 71152 Annual Follow-up of Selected Issues Condition Report CR-2016-25721, Indications of fuel defect for Unit 2; CR-2017-10852, Debris failure identified for rod in fuel bundle V27452; and CR-2017-13888, Adverse trend of foreign material intrusion into fuel assemblies in Unit 2 reactor

In conjunction with Susquehannas fuel vendor, Susquehanna determined that the most probable cause of the fuel defect identified in fuel bundle V27452 in 2017 was debris fret caused by foreign material.

Susquehanna conducted a thorough technical review of their foreign material exclusion (FME)program under CR-2017-13888. Susquehanna determined that there was a lack of program ownership for the FME program combined with a lack of oversight by the line organizations in regards to FME controls. Corrective actions included assigning an FME coordinator to fill the vacant role at the station, assign individuals within each line organization to become the FME lead within that organization, and to reinstate monthly FME steering committee meetings.

The inspectors reviewed the corrective actions and determined Susquehannas overall response to the issues were commensurate with the safety significance, were timely, and were generally effective. The inspectors noted a high number of FME-related condition reports were generated during the previous refueling outage but acknowledge this is most likely the result of the increased focus and oversight on FME controls.

The inspectors reviewed the condition reports and determined they were being entered at an appropriately low threshold and were being addressed commensurate with their safety significance.

Observations 71152 Annual Follow-up of Selected Issues Condition Report CR-2017-00530, MRC requested further evaluation on trend slower than typical DG starts; CR-2017-11996, A DG start for SO-024-001A 10.1 seconds to frequency

The inspectors reviewed corrective action CR-2017-00530, which was initiated by Susquehanna staff on January 6, 2017, to evaluate a trend in slower EDG start times that still met technical specification requirements. Additionally, the inspectors reviewed CR-2017-11996 to evaluate and correct the A EDG not meeting starting time requirements.

The inspectors review of CR-2017-00530 determined that Susquehanna engineering staff concluded there was not an adverse trend because a review of records since January 2009 documented normal operating start times from 7 to 8.9 seconds. The review also determined Susquehanna staff were generating condition reports at a lower threshold which resulted in an increased number of condition reports. The inspectors concluded the evaluation was conducted with sufficient technical rigor to support the conclusions.

CR-2017-11996 indicated that the A EDG reached frequency in 10.16 seconds versus the required 10 seconds during testing on June 19, 2017. The inspectors determined that Susquehanna staff implemented the applicable technical specification requirements, evaluated the problem in sufficient detail to identify that pneumatic valves USY-9 and/or USCV-9 actuated slowly resulting in a pneumatic delay, and that other causes were reasonably ruled out. Susquehanna staff replaced these valves and planned actions to revise maintenance activities and schedules for the pneumatic shuttle valves. The evaluation further noted the pneumatic starting circuit is only present in test mode and is locked out during an emergency mode start. The inspectors concluded the evaluation was of sufficient detail to identify the likely cause of not meeting the required start time and provided for corrective actions that addressed the cause.

EXIT MEETINGS AND DEBRIEFS

The inspectors verified no proprietary information was retained or documented in this report.

On October 18, 2018, the inspectors presented the quarterly resident inspector inspection results to Mr. Kevin Cimorelli, Site Vice President, and other members of the Susquehanna staff.
