PULSE COUNTING PERIOD METER OUTPUT DURING STARTUP TRANSIENTS

Technical Report ·
OSTI ID:4682241
The time response of a period meter whose input signal comes from a pulse-counting channel is calculated using a Ferranti Mercury autocode program. The period meter considered is the type for which the logarithmic characteristic is approximated by several diode pump circuits. The input excitation is a terminated ramp of reactivity. Other reactivity inputs may be treated. In particular the step change of reactivity may be used as the input excitation. Allowance is made for the effective time constants of the diode pump circuits and the period meter. The program may be used for instrument assessment and for safety and operations studies on reactors which use this type of period meter. An example of the use of the program is given. (auth)
