TEST RESULTS DL-S-151 T-550132 DETERMINATION OF COEFFICIENTS OF REACTIVITY SECTION I 1692.8 EFPH FIFTH PERFORMANCE

摘要

To determine the temperature and pressure coefficients of reactivity at zero power.nThe magnitude of the temperature coefficient at the plant operating temperature (500 F) was 1.42 (ΔK/ΔT) X 10-4. This is not as large as previous test performances, but doe3 indicate stable reactor operation at the new plant operating conditions. The determination of the pressure coefficient was omitted from this performance due to a lack of time and at the AEC's request.
