ANNUAL REPORT NO. 53 FOR THE YEAR 2011 LICENSE TR-1 DOCKET 50-70 MARCH 2012

GETR Annual Report No. 53 General Electric Test Reactor (Deactivated)

ANNUAL REPORT NO. 53 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. In this annual report, a summary of the status of the facility for the period of January 1, 2011 to December 31, 2011 is presented.

1.0

SUMMARY

The facility remains in essentially the same condition described in Annual Report No. 52. Entry into the reactor building was made for routine radiation surveys and a general examination of conditions throughout the building. The crane, elevator, and ventilation were serviced and tested in 2011 in anticipation of beginning remediation activities. Such activities have not begun.

Radiation and contamination levels remain at acceptable levels.

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 2011.

3.0 RADIATION AND CONTAMINATION Complete radiation and contamination surveys of the facility indicate that levels remain low. Results of the surveys are presented in Table 1. The radiation/contamination levels listed are representative but not necessarily maximum values.

The data below are from sample and dosimeter results accumulated during 2011.

These data are for the entire VNC site and include the effects of operations other than GETR.

GETR Annual Report No. 53 3.1 GETR Stack Although maintenance was performed on the stack in 2011, and the stack was tested, there has been no remediation effort performed for the GETR reactor. The ventilation system is not yet fully operational, and the stack air flow has not been calibrated. Thus no concentration data is available for 2011.

3.2 Air Monitors (Yearly average of all meteorological stations.)

Four environmental air-monitoring stations are positioned approximately 90 degrees apart around the operating facilities of the site. Each station is equipped with a membrane filter that is changed weekly and analyzed for gross alpha and gross beta-gamma.

Alpha Concentration:

Weekly Maximum, 6.38x 10-13 gCi/cc Weekly Average, 5.72 x 10-14 jCi/cc Beta Concentration:

Weekly Maximum, 3.81 x 10-14 ICi/cc Weekly Average, 7.20 x 10-15 gCi/cc 3.3 Gamma Radiation The yearly dose results for the year 2011 as determined from evaluation of site perimeter environmental monitoring dosimeters showed no departure from normal stable backgrounds.

3.4 Vegetation No alpha, beta or gamma activity attributable to activities at the GETR facility was found on or in vegetation in the vicinity of the site.

3.5 Off-Site Samples taken off the site indicate normal background for the area.

4.0 ACTIVITIES Routine inspections were conducted during this report period. There were no Page 2 of 4

GETR Annual Report No. 53 preventive or corrective maintenance activities performed having safety significance during the reporting period.

5.0 ORGANIZATION The organizational structure changed during 2011. The Site Manager is A.E.

McFadden. The GETR Facility Manager remains M.R.Schrag. The Manager, Regulatory Compliance and EHS is T.Dashiell.

6.0 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.
