GENERAL ELECTRIC TEST. REACTOR (DEACTIVATED)
ANNUAL REPORT NO. 28 The General Electric Company has maintained the General Electric Test Reactor (GETR) 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 1,1986, to December 31, 1986, 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. 27. 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 1986.
B. Changes There were no changes authorized by the Facility Manager pursuant to 10CFR50.59(a) and completed in 1986.
III. RADIATION LEVELS AND SAMPLE RESULTS AT ON- AND OFF-SITE MONITORING STATIONS The. data below are from sample and dosimeter results accumulated during 1986.
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. GETR Stack Total airborne releases (stack emissions) for 1986 are as follows.
Alpha Particulate < 0.399 pCi (predominantly radon-thoron daughter products)
Beta-Gamma Particulate 12.4 pCi 1

CETR Annual Report No. 28 i
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 < 4.9 x.10 Ci/cc (predominantly radon-thoron
-15 Average < 3.48 x 10 pCi/cc Beta Concentration:
Maximum
-1
< l.3 x 10 pCi/cc
-14 Average < 3.9 x 10 Ci/cc C. Gamma Radiation The yearly dose results for the year 1986 as determined from evaluation of site perimeter TLD environmental monitoring dosimeters showed readings within background.
D. Vecetation No alpha, beta or gamma activity attributable to activities at the CETR facility was found on or in vegetation in the vicinity of the site.
E. O f f- S i te l Samples.taken off the site indicate normal background for the area.
I-
! IV. c0NCLUSION The conditions at the GETR reflect a year of safe shutdown conditions.
