Subject:
Modified Core Configuration for the Westinghouse Nuclear Training Reactor, License R-119, Docket 50-87 Gentlemen:
The Westinghouse Electric Corporation hereby submits for your in-formation a document titled " Safety Considerations for the 24 Element Graphite-Reflected Core".
This document was prepared for review by the Westinghouse Nuclear Training Reactor Safeguard Committee in accordance with Section 4.0 of the Technical Specifi-cations.
The Reactor Safeguard Committee reviewed the proposed core configuration, operational procedures, and the attached do -
cument.
It is the judgement of the Reactor Safeguard Committee that the proposed core configuration does not present or constitute any unreviewed safety questions or involve a change in the technical specifications.
Based on this decision by the Reactor Safeguard Committee and in accordance with the provisions of 10 CFR 50.59 (a) (1) (iii),.the testing program for the 24 Element Graphite-Re-flected Core commenced during January 1981.
The Westinghouse Nuclear-Training Reactor as'it'is currently con-figured (Fig. 1) utilizes a quantity of SNM that exceeds the formula quantity.
The modified. core configuration (Fig. 2) is being' con-sidered in an effort to reduce the SNM inventory to less than the formula' quantity.
Basically the modified core configuration contains about 4800 grams of Uranium - 235 with graphite reflector assemblies utilized to eccnomize the neutron flux.
If you have anyl questions concerning this transmittal please. contact me by writing to the above address or call me on (412) 373-4652.
