Abstract

Following the large interest aroused in the world on Accelerator Driven Systems (ADSs), the TRASCO Italian national research program for nuclear waste transmutation has paid special attention to the development of suitable numeric al tool s for studyin g operational tran sients and acc idental sequences of ADS-like systems. At present a multigroup dedicated neutronic code for subcritical systems coupled with a simplified thermal-hydraulic code (NILO-TESTE) and a modified version of the RELAP5/PARCS code are both available. The aim of this work is to test and compare these two coupled codes against a set of typical transients for lead-bismuth cooled subcritical systems under cover gas injection enhanced natural circulation.
