Title: TEMPERATURE COEFFICIENT MEASUREMENTS ON A CRITICAL MOCK-UP OF EBR-I

Abstract

A rough mock-up of the EBR-I reactor was built in the ZPR-III critical assembly machine, with resistance heaters in the core and inner blanket. The variation of reactivity with core temperature was observed. Lateral expansion was measured as the core was heated. A temperature coefficient of --0.42 inhour per degree Centigrade was observed when the core alone was heated, and --0.72 inhour per degree Centigrade was observed when the core and inner blanket both were heated. Essentially all of these coefficients are attributable to volume expansion. (auth)
