Knowledge of time-dependencies (and magnitudes) of feedback components is necessary for interpretation and understanding of transient behaviors. Described herein is one analysis of negative insertion (approx. 36 cents) of a control rod from full power during Experimental Breeder Reactor-II (EBR-II) run 93a. The time-dependencies of the component feedbacks have been analyzed using 24 channels in the EROS computer code. Seventy distinct temperature coefficients of reactivity were used in conjunction with this 24-channel EBR-II model. These temperature coefficients of reactivity were obtained using an addition (TEMCO) to the EBRPOCO code.
