A comprehensive analysis was made of the nuclear characteristics of the SM-1 Core I. Comparison of analytical and experimental results for neutron ages and core reactivities of a variety of cases investigated showed that the MUFT III with P-1 slowing down approximation gives the best results. At startup the core reactivity and rod bank worth under various operating conditions are investigated and compared to experiment. Core lifetime was calculated to be 16.8 MWYR compared to 16.4 MWYR experimental. The temperature coefficient was calculated and compared to experiment as function of burnup. Flux distribution, temperature coefficient, effective delayed neutron fraction, and core life were analyzed by one and two group modified theory and series expansion calculations. (auth)
