Description
A critical experiment on the interaction effect between two rectangular cores moderated with light water was performed at Tank-type Critical Assembly (TCA) of JAERI. Each core was composed of the array of UO2 fuel rods of which 235U enrichment was 2.6 w/o. The lattice cell was a square type of which the pitch was 1.956 cm corresponding to the water-to-fuel volume ratio of 1.83. From the obtained critical water heights, reactivity effects from one unit to another through water gap and negative reactivity of water gap and subcriticality of single units were measured by use of water level worth method as a function of the distance between two units. Calculations for critical configurations were also made with Monte Carlo code KENO-IV in JACS system, and compared with the measured reactivity effects. (author)
