Abstract : The design of a system for the measurement of the transient control rod motion of the AFRRI-TRIGA pulse reactor is presented. Data on the transient rod motion and its effect on the reactor pulse are presented and discussed. It is found that the finite travel time of the rod has an effect on the time of the pulse peak and the magnitude and shape of the pulses above $3.00. For pulses on the order of $1.00, the beginning of the power transient was found to be sensitive to the transient rod bounce. (Author)
