ANNUAL REPORT NO. 51 FOR THE YEAR 2009 LICENSE TR-1 DOCKET 50-70 MARCH 2010

THIS PAGE INTENTIONALLY LEFT BLANK GETR Annual Report No. 51 General Electric Test Reactor (Deactivated)

ANNUAL REPORT NO. 51 General Electric Company has maintained the General Electric Test Reactor (GETR) in a deactivated status under the authority of Amendment No. 16 to License TR-1, Docket 50-70, issued September 30, 1992. In this annual report, a summary of the status of the facility for the period of January 1, 2009 to December 31, 2009 is presented.

1.0

SUMMARY

The facility remains in essentially the same condition described in Annual Report No. 50. Entry into the reactor building was made for routine radiation surveys and a general examination of conditions throughout the building.

Radiation levels remain essentially unchanged.

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 10CFR5O.59(a) and completed in 2009.

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 2009.

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

3.1 GETR Stack Not operated.

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

GETR Annual Report No. 51 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, 7.36 x 10-13 ipCi/cc Weekly Average, 5.59 x 10-14 itCi/cc Beta Concentration:

Weekly Maximum, 7.29 x 10-13 !vCi/ccI Weekly Average, 9.30 x 10-14 ViCi/cc 3.3 Gamma Radiation The yearly dose results for the year 2009 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 preventive or corrective maintenance activities performed having safety significance during the reporting period.

5.0 ORGANIZATION The management and operations organization for the GETR is described in Technical Specification 6 (Figure 1) of License TR-1. The organizational structure changed in 2009. The Level 1 Organizational Head for 2009 was D.W. Turner. The Level 2 Facility Manager during 2009 was J. L.Grinold for the first half of 2009, and D.W. Turner for the remainder of theyear. At year-end, 2009, M. R.Schrag became the Level 2 Facility Manager Page 2 of 4

GETR Annual Report No. 51

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.
