GENERAL ELECTRIC TEST REACTOR (DEACTIVATED)
ANNUAL REPORT No. 31 The General Electric Company has maintained the General Electric Test Reactor (CETR) in a deactivated status under the authority of Amendment No. 14 to License TR 1, Docket 50 70, issued February 5, 1986. This annual report summarizes the status of the facility for the period January 1,1989, to December 31, 1989, as required by Technical Specification 6.6.1 to License TR 1.
I.
SUMMARY
l The facility remains in essentially the same condition described in Annual Report No. 30.
Entry into the reactor building was made for routine radiation surveys and a general check of conditions throughout the building.
II.
STATUS A.
Maintenance There were no major preventive or corrective maintenance activities having safety significance performed during 1989.
B.
Chances There were no changes authorized by the Facility Manager pursuant to 10CFR50.59(a) and completed in 1989.
III.
RADIATION LEVELS AND SAMPLE RESULTS AT ON-AND OFF SITE MONITORING STATIONS l
The data below are from sample and dosimeter results accumulated during 1989.
l Except for the GETR stack data, these data are for the entire VNC site and include the effects of operations other than the GETR.
A.
CETR Stack 1
Total airborne releases (stack emissions) for 1989 are as follows.
Alpha Particulate, < 0.163 pCi (predominantly radon thoron daughter products)
Beta Camma Particulate, < 1.70 Ci 1

B.
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 which is changed weekly and analyzed for gross alpha and gross beta gamma.
Alpha Concentration:
Maximum
< 5.7 x 10 15 pCi/cc (predominantly radon thoron Average
< 3.1 x 10-15 pCi/cc Beta Concentration:
Maximum
< 5.4 x 10' 4 pCi/cc i
Average
< 2.33 x 10 Ci/cc C.
Carnma Radiation The yearly dose results for the year 1989 as determined from evaluation of site perimeter.TLD environmental monitoring dosimeters showed readings within background.
D.
Veneration 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.
E.
Off-site l
Samples taken off the site indicate normal background for the area.
IV.
CONCLUSION l
i The conditions at the GETR reflect a year of safe shutdown conditions.
