5. Evaluation of Exercises and Drills (Inspection Procedure 88051)

a. Inspection Scope On September 18, 2019, the NFS staff conducted a biennial emergency exercise in accordance with the emergency plan and the provisions of 10 CFR 70.22(i)(3)(xii). Prior to the exercise, the inspectors reviewed the proposed emergency scenario submitted to the NRC on July 11, 2019 and discussed the objectives with the emergency preparedness program manager to determine whether the exercise included a type of scenario that was postulated as most probable for the site. The inspectors also assessed whether the exercise scenario was adequate to test the elements of the emergency plan. The inspectors discussed the administrative controls in place to prevent disclosure of the exercise scenario to the participants with the exercises lead 14

controller. Prior to the exercise, the inspectors conducted a tour of the NFS facility to verify that there was no pre-staged equipment or markings that could reveal hints of the planned emergency scenario. Additionally, the inspectors reviewed the list of offsite responders that were planning to participate in the exercise to verify that the licensee had invited the appropriate offsite response organizations as required in 10 CFR 70.22(i)(3)(xii).

The inspectors observed and evaluated the emergency exercise, which consisted of a fire that caused damage to part of a building structure containing licensed material. The simulated fire was of significant size and duration to eventually elevate the incident to a Site Area Emergency. In addition to the fire emergency, the scenario included the rescue and medical treatment of various victims with different degrees of injuries and radiological contamination.

At the initiation of the emergency exercise, the inspectors observed the participants actions to follow up on the fire alarm indications and the reporting of the Emergency Control Director (ECD), On-scene Coordinator (OSC), and onsite fire brigade staff to the Emergency Response Facility. The inspectors observed the initial coordination between the ECD and the OSC to verify that all required positions were fully staffed in accordance with the emergency plan. The inspectors evaluated whether the OSC maintained proper command and control of the emergency response team and coordinated actions with the offsite emergency responders.

The inspectors evaluated if the on-scene emergency response activities were appropriate to meet the objectives of the exercise scenario. The inspectors observed the fire brigades search and rescue activities for the simulated victims. The inspectors observed the establishment of barriers and a triage area to provide urgent medical care to the victims. The inspectors observed the licensees practices for identifying and controlling the spread of simulated contamination. The inspectors also observed the on-scene coordination with offsite ambulance services, including Wings Air Rescue, to transport the victims to local hospitals. The inspectors also observed the coordination with the Erwin Fire Department to authorize and execute fire mitigation actions.

The inspectors observed the activation of the Emergency Control Center (ECC) under the leadership of the ECD and verified that all required positions were fully staffed within the required timeframe in accordance with the emergency plan. At the ECC, the inspectors evaluated whether the licensee assessed the accident scenario, analyzed the plant conditions, and classified the event in accordance with the emergency response procedures. The inspectors observed the radiologically assessment staff perform offsite dose assessment and evaluated whether the licensee used dose assessment results to inform its emergency response decisions, particularly for protective action recommendations (PARs).

The inspectors reviewed the initial offsite notifications to verify these met the timeliness requirements specified in the emergency plan and were accurate in content. The inspectors reviewed the press releases issued by the ECC communicators to verify these were approved by the ECD prior to issuance and were in accordance with the emergency plan. The inspectors also verified that the onsite communications to the occupational workers were consistent with the PARs approved by the emergency response organization.

15

The inspectors observed the staff critiques of the emergency exercise and verified if the critiques were effective at evaluating the appropriateness of the emergency plan, along with emergency procedures, facilities, equipment, training of personnel, and overall effectiveness of the response. The inspectors also verified whether the critiques used individuals not having direct implementation responsibility for the emergency plan. The inspectors verified if the licensee documented any deficiencies in the PIRCS. The licensee documented the critique results in PIRC 76385, 2019 NRC Graded Biennial Exercise EP Critique, dated September 18, 2019.

b. Conclusion

No violations of more than minor significance were identified.

D. Other Areas

1. Quarterly Resident Inspector Observations of Security and Material Control and Accounting (MC&A) Personnel and Activities

a. Inspection Scope During the inspection period, the inspectors conducted observations of security and MC&A personnel and activities to ensure the activities were consistent with applicable license, procedure, and regulatory requirements. These observations took place during normal and off-normal plant working hours.

These quarterly resident inspectors observations of security force personnel and activities did not constitute any additional inspection samples. Rather, they were considered an integral part of the inspectors' normal plant status reviews and inspection activities.

b. Conclusion

No violations of more than minor significance were identified.

2. Written Event Report 2019-001, Criticality Accident Alarm System Speaker Failure in Building 333 LEU (Event Notification 54218)

a. Inspection Scope On August 13, 2019 the licensee identified that a speaker in the low-enriched uranium (LEU) area of Building 333 was not operating when a series of public address announcements were made. The licensee implemented compensatory measures to limit access in the affected area to only those personnel with radio communication with the alarm room. The licensee also tested the system and confirmed that the criticality accident alarm system (CAAS) and the Fire Alarm system were not audible in the Building 333 LEU area. There were no other areas of the plant affected. On the same day, the licensee replaced the affected speaker and restored the system to normal operation. The event did not result in actual consequences to plant workers or the public.

16

On August 14, 2019, the licensee submitted event notification54218 to the NRC followed by a 30-day written event report (WER) on September 12, 2019 (ADAMS ML19262D347). The inspectors reviewed the information provided in the reports and interviewed licensee staff to assess the level of NRC response for the reported condition in accordance with the guidance of Management Directive 8.3, NRC Incident Investigation Program.

b. Conclusion

This item remains open pending the review of licensees corrective actions and will be included in the scope of routine NCS inspections for closure.

3. (Retracted) Event Notification 54255, Unplanned Contamination Event

a. Inspection Scope On September 4, 2019, the licensee reported via EN 54255 that a glass component used for a licensed process had failed, resulting in an unplanned contamination event.

The release was limited to an area inside of the Radiologically Controlled Area designed for radiological work. The licensee reported that airborne radioactivity samples were below action levels. The licensee also reported that cleanup and decontamination activities were safely and promptly initiated, but due to the complexity and space constraints of the system components, there was a chance that normal access to the area would not be restored within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. The event did not result in personnel contamination, exposures to the public, or releases to the environment.

On September 16, the licensee retracted the event on the basis that the unplanned contamination event was decontaminated to levels that did not require access to be restricted by imposing additional radiological controls for more than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Thus, the licensee concluded that the event did not require a report per 10 CFR 70.50(b)(1)(i).

The inspectors interviewed licensee staff and conducted walk-downs of the affected area to follow up the licensees response to the event. The inspectors also reviewed the information provided in the reports and the licensees corrective actions to assess the level of NRC response for the reported condition in accordance with the guidance of Management Directive 8.3, NRC Incident Investigation Program. The inspectors also verified that the licensee provided a valid basis for retracting the event notification.

b. Conclusion

No violations of more than minor significance were identified. This item is considered closed.

E. Exit Meetings The inspection scope and results were presented to members of the licensees staff at various meetings throughout the inspection period and were summarized on August 15 and September 18, 2019, and at the end of the quarter on October 28, 2019, to J.

Stewart and staff. Proprietary and classified information were discussed, but not included in this report.
