j GENERAL ELECTRIC TEST REACTOR (DEACTIVATED)
ANNUAL REPORT NO. 30 1
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 1,1988, to ,
December 31, 1988, as required by Technical Specification 6.6.1 to License TR-1.
I.
SUMMARY
The facility remains in essentially the same condition described in Annual Report No. 29. 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 1988.
B. Chances The following change was authorized by the Facility Manager pursuant to 10CFR50.59(a) and completed in 1988.
GETR Enclosure Exhaust Fan
Description:
The exhaust fan was rewired to connect it to the Site Emergency Alarm System panalarm display located in Building 102B.
Change was instituted so that interruption of fan operation can be detected and prompt action taken.
Safety Analysis: Permits quicker response to interruption in fan operation.

GETR Annual R3 port No. 30 III. RADIATION LEVELS AND SAMPLE RESULTS AT ON- AND OFF-SITE MONITORING STATIONS The data below are from sample and dosimeter results accumulated during 1988.
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 Total airborne releases (stack emissions) for 1988 are as follows.
Alpha Particulate, < 0.150 pCi (predominantly radon-thoron daughter products)
Beta-Gamma Particulate, < 4.19 pCi 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:
-15 Maximum < 4.8 x 10 Ci/cc (predominantly radon-thoron
-15 Average < 2.73 x 10 pCi/cc Beta Concentration:
Maximum < 9.4 x 10' 4 pCi/cc Average < 2.69 x 10 pCi/cc C. Gamma Radiation i
The yearly dose results for the year 1988 as determined from evaluation of site perimeter TLD environmental monitoring dosimeters showed readings within background.
D. 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.
E. Off-Site Samples taken off the site indicate normal background for the area.
