NS SAVANNAH CORE 1 NUCLEAR CHARACTERISTICS
Nuclear characteristics of the N.S. Savannah's Core 1 are based on improved calculations and measurements taken at about 10 percent of the core lifetime. An initial physics test program determined core excess reactivity, flux and power distribution, control rod group and pattern worths, and power-peaking values for various control rod patterns. Core physics tests included measurements of operating reactivity coefficients and calibrations of various control rod Groups. All full power values are based on a core power of 74 MW-t which delivers approximately 20,000 shp under normal operating conditions. Initial excess reactivity and the measured worths of various control rod groups and patterns at ambient temperature were determined by the water height method during zero power tests. The measured reactivity coefficients, which included the temperature coefficient, power Doppler coefficient, and the pressure coefficient, were calculated using both one and two-dimensional models.
