RADIONUCLIDE RELEASE FROM AERO-SPACE NUCLEAR REACTOR FUELS Ⅰ. SAFETY ANALYSIS OF PULSED NEUTRON IRRADIATION OF DRY FUEL

摘要

The safety of in-core exposures of ROVER/NERVA fuel to pulsed neutron irradiation has been analyzed. Exposure in a dry environment of fuel specimens containing one gram of u235 to a TRIGA Mark F power transient (following a three dollar step increase in reactivity) vas examined. These examinations indicate that expected temperatures, pressures and radiation levels are well within required safety limits.
