• Note (General): Pulsed neutron experiments have been performed on FCA V-1, the physics mockup core for the JOYO. Neutron decay curves have been measured at several different re-activities from the delayed critical down to -6\. In all cases, single exponential decays are observed after the constant delayed component being subtracted. Prompt neutron decay constant $\alpha$ and the reactivity $\mu$pindoller unit are determined for each decay curve. Both $\alpha$'s and $\mu$'ps show no dependence on detector positions or energy responses in the measured reactivity range (down to -2\). $\alpha$ and $\mu$p hold good linear relation down to -6\.The prompt neutron decay constant at delayed critical, $\alpha$c is determined as 0.341 0.031x105 sec-1. $\alpha$c calculated by SNKPARAM with JAERI-FAST set is about 13\%larger than the experimental value.; None
