  • Meeting minutes of the GE VNC as low as reasonable achievable committee for the past 2 years
  • GE VNC dosimetry records for the past 2 years-7-
  • Annual RPP Review for the past 2 years
  • Survey results for daily, weekly, monthly, routine, and special surveys for the past 2 years
  • Calibration and periodic check records for radiation monitoring instruments for the past 2 years
  • Annual Report No. 58 for the GE-Hitachi NTR, dated April 18, 2018 b. Observations and Findings The inspector toured the facility and interviewed licensee personnel, observing practices regarding the use of dosimetry, radiation monitoring equipment, and placement of radiological postings and barriers and determined that they were appropriate.

The licensee used a National Voluntary Laboratory Accreditation Program-accredited vendor to process personnel dosimetry. Radiation work permits were used for all activities to track workers and dose sources with appropriate alarm set points depending on each different area. Due to the reduced staffing levels, exposure amounts have increased for the two active license holders, though one is receiving the majority of the increase as the primary reactor operator. The facility has an administrative limit of 300 millirem/quarter. On occasion, a request for additional exposure has been submitted and approved. The inspector noted that, even with these increases, doses were well within the regulatory limits and consistent with the operations of the NTR.

The licensees RPP was established through various standards and procedures in use at the facility. These were maintained and available on-line. The program included requirements that all personnel who performed work in association with radioactive material receive training in radiation protection, policies, procedures, requirements, and facilities. These were being tracked on-line and completed at the required frequency. Additionally, the annual review of the RPP was being completed internally by different managers at the required frequency.

The inspector reviewed survey and calibration records and found that they were being completed as required with no safety issues identified. The inspector also observed surveys being performed and found the process appropriate. Copies of current notices to workers were posted in the facility.

The inspector reviewed the records documenting on-site and off-site effluent and environmental monitoring stations for the past 2 years. Airborne and water releases were below regulatory limits. Off-site samples indicated normal background.

c. Conclusion The inspector verified that the licensees RPP was effective in minimizing radiation doses to individuals through training, notices to workers, radiation monitoring and surveys, and calibrated equipment. The program met regulatory-8-

requirements. Effluent releases, effluent monitoring, and environmental monitoring satisfied license and regulatory requirements.

8. Design Changes a. Inspection Scope (IP 69001)

To ensure the requirements of 10 CFR 50.59, Changes, tests and experiments, the TS, and the licensees administrative procedures were being met, the inspector reviewed the following:

  • Annual Report No. 58 for the GE-Hitachi NTR, dated April 18, 2018
  • 10 CFR 50.59, Determination Worksheet b. Observations and Findings During the inspection, the licensee conducted a maintenance activity to repair secondary cooling system flowmeter. Testing was performed and results correlated with previous data. All changes were reviewed and approved by the senior reactor operator/NTR Manager, Regulatory Compliance, Vallecitos Technological Safety Council, and the VNC Site Manager as required.

c. Conclusion Records indicated that changes at the facility were acceptably reviewed in accordance with 10 CFR 50.59 and applicable licensee administrative controls.

9. Committees, Audits and Review a. Inspection Scope (IP 69001)

The inspector reviewed the following to verify compliance with TS Section 6.2, Independent Reviews:

  • Annual Report No. 58 for the GE-Hitachi NTR, dated April 18, 2018
  • Vallecitos Technical Safety Council (VTSC) Committee Meeting Minutes for the last 2 years b.

VTSC composition, meeting quorums, and meeting frequency followed the requirement of VSS 1.1.

The inspector also reviewed the RCs periodic audits of the facility operations, maintenance, and administration. The independent group was completing the audits within the required 2-year cycle.

-9-

c. Conclusion The review and audit program was being conducted acceptably by the NSRG as stipulated in the TS.

10. Emergency Preparedness a. Inspection Scope (IP 69001)

To ensure that the requirements of the E-Plan were being met, the inspector reviewed:

  • GE Hitachi Vallecitos Nuclear Center (VNC) Integrated Contingency Plan, dated October 2015
  • VNC Reactor and Radiological - Radiological E-Plan, reviewed November 2013
  • SOP 8.0, Emergency Procedures
  • Memorandum of understanding with Valleycare Medical Center, Alameda County Sheriffs Office, and Paramedics Plus
  • VNC Biennial Exercise and Building Evacuation Drills for the past 2 years
  • Various VNC Emergency Training Records b. Observations and Findings The E-Plan currently in use was being properly maintained by the licensee. The inspector noted that the E-Plan was applicable to the VNC campus and the NTR has implemented specific procedures. These procedures were readily available in the NTR control room and offices.

The inspector reviewed records for the monthly alarm testing and the semi-annual emergency equipment cabinet inventory check and found that they were being completed as required.

Training for the facility operators, staff, and members of the VNC having emergency response duties included completion of an initial training program and the performance of annual review and an examination. Several staffers have completed respirator program training as well which included annual fit test, medical, and equipment checks. The inspector noted through records and interviews with licensee personnel that the training and examination was completed satisfactorily.

The inspector also noted that off-site first responders participated in on-site orientation and training. Participants included Paramedics Plus Alameda, the Alameda County Sheriffs Office, and the Cal Fire department.

Through the review of drill scenarios and record reviews, the inspector determined that key emergency response personnel can respond to an emergency condition as required. The annually emergency evacuation drill was conducted as required by the E-Plan. The biennial comprehensive emergency

  • Annual Report No. 58 for the GE-Hitachi NTR, dated April 18, 2018
  • SOP 12.0, Preventive Maintenance - NTR,
  • NTR Preventive Maintenance Index and Completion Records b. Observations and Findings The inspector reviewed the corrective maintenance cards for minor issues for the past 2 years, with no issues identified. Major maintenance activities discussed in the annual reports were previously reviewed by the inspector. Routine and preventive maintenance were well controlled and documented in a tracking system.

A review of the NTR preventive maintenance log indicated that all maintenance activities were generally conducted consistent with applicable requirements and that any modifications had been properly evaluated in accordance with 10 CFR 50.59. After all maintenance items were completed, system operational checks were performed to ensure the affected systems were operable before returning them to service.

c. Conclusion Maintenance was performed and logs and records maintained consistent with the TS and licensee procedure requirements.

Radioactive material to be used on site were also transferred to the broad scope license and distributed by Environmental Health and Safety. The irradiated material was held for decay until levels were below established limits. The transfer forms indicated the material had been surveyed prior to custodial change. The program for radioactive material transfer and transport were consistent with procedural requirements.

The inspector also verified that individuals responsible for transporting radioactive material received radioactive material and transportation of radioactive material training. They are certified every 2 years.

c. Conclusion Radioactive material shipments were made according to procedures and regulatory requirements.
