A Pressure Tube Fast Test Reactor Concept

摘要

This study presented an innovative fast-spectrum testreactor borrowing from the CANDU pressure-tubereactor. Based on our neutronic evaluation of theconcept, a peak fast flux of >10~(15) n/cm~2s wasachieved. We significantly modified the CANDU concept by altering the fuel type, assembly size,power density, reflector material and coolant. Afterthe writing of this summary an initial thermalhydraulic evaluation of several potential coolants hasbeen completed [5]. It concluded that a reasonablethermal-hydraulic design appears more achievablewith helium than it is with steam. This will be thesubject of a future publication. To further validatethis concept functionality more investigation isneeded in the areas of coupled neutronic/thermalhydraulic and safety aspects.
