Interim waste storage for the Integral Fast Reactor Fuel Cycle Demonstration

An interim storage system design and operating strategy were developed for implementation in the Integral Fast Reactor Fuel Cycle Demonstration. Waste characteristics and thermal power levels as a function of time were established for the principal waste streams. A passive convective cooling system has been designed and a thermal model of the system was developed. Heat transfer in a sealed storage facility was also modeled. The various design parameters, waste characteristics and heat transfer models were then used to investigate the interrelationships between systems to determine a flexible strategy that would minimize the number of required waste containers and storage space
