VBWR Annual Report No. 59 3.0 ROUTINE PATROLS The facility was inspected weekly, quarterly, and annually in accordance with written procedures.
Patrols identified the following:
Unchanged efflorescence on the basement walls and floor.
Unchanged spalling of concrete, corrosion stains and rebar corrosion on the Basement Pump Foundation pedestal.
Unchanged Seepage of water into the basement bore location.
These conditions have been evaluated, pose no threat to structural integrity, and are being monitored. The structural condition of the facility is being actively monitored and is structurally sound to ensure maximum protection for public health and safety.
4.0 RADIATION AND CONTAMINATION Complete radiation and contamination surveys of the facility indicate that levels remain low.
Results of the surveys are presented in attachment 1. Air sampling results are presented in attachment 2. The radiation/contamination levels listed are representative but not necessarily maximum values.
Analytical results of groundwater samples are available in the Annual Environmental Report submitted on February 15, 2024.
5.0 ACTIVITIES Inspection of the installed gauges showed no propagation of concrete cracking.
There were no preventive or corrective maintenance activities performed having safety significance during the reporting period.
6.0 ORGANIZATION The Site Manager is C. Martinez. The VBWR Facility Manager is J. G. Ayala. The Manager, Regulatory Compliance and EHS remains J. Smyly.
Page 2 of 3
VBWR Annual Report No. 59 7.0 CONCLUSION GE Hitachi Nuclear Energy concludes that the deactivated VBWR is being maintained in a safe shutdown condition.

ANNUAL REPORT NO. 65 FOR THE YEAR 2023 LICENSE TR-1 DOCKET 50-70 MARCH 2024 Val/ecitos Nuclear Center Sunol, California
GETR Annual Report No. 65 General Electric Test Reactor (Deactivated)
ANNUAL REPORT NO. 65 GE Hitachi (GEH) has maintained the General Electric Test Reactor (GETR) in a deactivated status under the authority of Amendment No. 17 to License TR-1, Docket 50-70, issued October 22, 2007 as specified in TS 6.6.1 to Amendment No. 14, issued February 5, 1986. In this annual report, a summary of the status of the facility for the period of January 1, 2023 to December 31, 2023 is presented.
1.0
SUMMARY
The facility remains in predominately the same condition described in Annual Report No. 64. Entry into the reactor building was made for routine radiation surveys and a general examination of conditions throughout the building. The crane, and ventilation were serviced and tested in 2023 in anticipation of beginning remediation activities.
Such activities have not begun.
Structural conditions and radiation and contamination levels remain at acceptable levels. Environmental data is maintained on site and available for review.
2.0 STATUS OF FACILITY In accordance with written procedures, the Facility Manager controls access to the containment building and general systems. The facility continues to be in deactivated status. There were no changes authorized by the Facility Manager pursuant to 10CFR50.59{a) in 2023.
3.0 ROUTINE PATROLS The facility was inspected weekly, quarterly, and annually in accordance with written procedures.
The presence of minimal efflorescence was identified on facility basement walls during the annual inspection. This condition was evaluated and determined to not pose a structural issue.
The structural condition of the facility remains actively monitored, stable and structurally sound to ensure maximum protection for public health and safety.
4.0 RADIATION AND CONTAMINATION Complete radiation and contamination surveys of the facility indicate that levels remain low. Results of the surveys are presented in attachment 1. Air sampling results are Page 1 of 2
GETR Annual Report No. 65 presented in attachment 2. The radiation/contamination levels listed are representative but not necessarily maximum values.
4.1 GETR Stack Although maintenance was performed on the stack in 2023, and the stack was tested, there has been no remediation effort performed for the GETR reactor. The ventilation system is operational, but not currently in use.
Analytical results of groundwater samples can be found in the Annual Environmental Report submitted on February 15, 2024.
5.0 ACTIVITIES Inspection of the installed gauges showed no propagation of concrete cracking.
There were no preventive or corrective maintenance activities performed having safety significance during the reporting period.
6.0 ORGANIZATION The Site Manager is C. Martinez. The GETR Facility Manager is J.G. Ayala. The Manager, Regulatory Compliance and EHS remains J. Smyly.
7.0 CONCLUSION
GE Hitachi Nuclear Energy concludes that the deactivated GETR is being maintained in a safe shutdown condition. The inspections, access control, and administratively controlled activities ensure maximum protection for the public health and safety. The procedures will be continued to maintain this high level of protection.
