A stand-alone version of the integrated fuel/coolant interaction (IFCI) code has been developed and demonstrated. IFCI is a best-estimate code that attempts to model all phases (mixing, triggering, propagation, and expansion) of fuel/coolant interactions (FCIs) in as mechanistic a manner as possible. Modules and references associated with reactor cores, detailed structural information, and extraneous code linkages have been removed in order to create a useful tool to study FCI progression. The size of the source code has been decreased almost 70%. The executable is approximately half the previous size, and compile time has been decreased by almost 20%. IFCI has been exercised for a limited suite of experimental cases up to and including explosive FCIs. The basic features of IFCI and the assessment against explosive results from the Integral Effects Tests Series (IET-8, in particular) are presented in this paper.
