BNL-TWIGL has enabled us to determine the dependence of the CRDA peak power and fuel enthalpy on the core inlet subcooling and rod drop speed. The results show that the peak power and fuel enthalpy increases rapidly with inlet subcooling up to a subcooling of approx. 20/sup 0/F and become relatively insensitive at higher subcoolings. Furthermore, as the rod drop speed is increased, the calculations show that the peak fuel enthalpy increases by less than or equal to 30%. It must be pointed out that in all cases studied the peak fuel enthalpy was found to be well below the 280 cal/gm criterion.
