Evaluation of MSM for assessing subcritical reactivities in FFTF

Conference ·
OSTI ID:7014403

Modified Source Multiplication (MSM) is the method that will be used to monitor the subcritical reactivity of the Fast Flux Test Facility (FFTF) reactor during startup, acceptance testing, shutdown and refueling operations. Evaluation of the method as a subcritical reactivity monitoring system in FFTF was provided by the following types of measurements: (a) a calibration of MSM with an Inverse Kinetics Rod Drop (IKRD) method; (b) measurement of the reactivity of a variety of subcritical states by both the MSM and IKRD method; and (c) measurement of subcritical reactivities by MSM and comparison of results with calculated reactivities for subcritical states where inverse kinetics can no longer be used.
