Abstract

It has been proposed that various reactor parameters, including temperature and pressure, could affect the measured load of fuel assemblies during refueling at the Hinkley Point B Advanced Gas Cooled Reactor. After processing station logs and matching the appropriate parameter values to a specific refueling event it was found that there is no detectable correlation between deviations in the measured load and the vessel pressure or the temperatures of various core regions. There is however a strong correlation however between the Dome Differential Pressure and deviation in the measured load relative to the absolute assembly weight, of up to 100kg.
