GENERAL ELECTRIC NUCLEAR TEST REACIOR ANNUAL REPORT NO. 23 I.
INIRODUCTION 1
This report summarizes the operation, changes, tests and experiments at the Nuclear Test Reactor (NIR) which were authorized pursuant to License R-33 and 10CFR50, Section 50.59, for the period January 1,1982, through December 31, 1982.
II.
GENERAL A.
The reactor was operated at or above critical for 995.3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />. A total of 380 startups were made.
Six (6) scrans and three (3) unscheduled shutdowns occurred during this period.
B.
The average annual radiation exposure to f acility personnel was 1.2 Rem.
C.
There was one occurrence that required the notification of the NRC.
During a routine inspection of the General Electric Nuclear Test Reactor (NTR) prior to startup on April 12, 1982, it was discovered that one of the two scram springs on Safety Rod #4 was broken. The broken spring did not prevent the rod from operating. However, the scram time for the rod was 432 msec versus a limit of 270 msec required by the technical specifications. There was no safety problem as only one of the four safety rods is required to scram the reactor. The broken spring was replaced on April 12, and all four rods scrammed within the required time limit.

III.
ORGANIZATION One change was made to the NIR organization in 1982. The position of l
Manager, Reactor Irradiations (RI), was discontinued, and the Manager, Advanced Nuclear Applications (ANA), was delegated facility manager responsibilities for the NIR.
As with the former Manager, RI, the Manager, ANA, reports to the Manager,' Irradiation Processing Operation.
IV.
CHANGES, TESTS, AND EXPERIMENTS APPROVED BY IHE MANAGER, ADVANCED NUCLEAR APPLICATIONS A.
Channes Pursuant to 10CFR50.59(a), the Manager, Advanced Nuclear Applications, authorized two (2) changes during 1982. The changes are briefly described below: t
7_.
f n
.O 1.
Facility Personnel
==
Description:==
See Section lil, Organization.
Safety Analysis: This change is entirely administrative.
It is a change in-the Facility Manager's title and organization but does not alter his functions or duties.
2.
Secondary Cooling System
==
Description:==
A temporary discharge line for the secondary cooling system made of PVC was replaced with a permanent-line constructed of 1-1/2-inch galvanized pipe.
Safety Analysis: This was basically a material replacement.
There were some routing changes which have no safety significance.
B.
Experiments There were a total of 883 Individual experiments reviewed, approved and performed in 1982.
No new types of experiments were perroceed which are different from those already described in Section 7 0 of the Summary Safeguards Report for the General Electric Nuclear Test Reactor, APED-4444A, or as specified in annual reports submitted since the submittal of APED-4444A.-
C.
Tests No special tests were performed during 1982 that required authorization of the facility manager.
V.
CONCLUSION The overall operating experience of the Nuclear Test Reactor reflects another year of safe, ef ficient operations. We anticipate the operation of the reactor will continue on this basis.
