OUTPUT OF THE TYPE 4051 AND 4061 PERIOD METERS DURING STARTUP TRANSIENTS

Technical Report ·
OSTI ID:4165211
A digital computer program for the Ferranti Mercury computer is described. With this program, startup transients for the recently developed period meters, Types 4051 and 4061, may be computed. The reactivity disturbances considered are steps and terminated ramps of reactivity. Due allowance is taken of the variable time constant which is a feature of these period meters. The reactor may be critical or subcritical initially as desired, and the initial input time constant of the period meter may be zero or finite. Some representative transients obtained with the program are presented and discussed. (auth)
