Simulation of the VVER-1000 pump start-up experiment in the OECD/DOE/CEA V1000CT benchmark by the FLICA4/CRONOS2 coupled code system

Abstract : In the framework of joint effort between the Nuclear Energy Agency (NEA) of OECD, the United States Departement of Energy (US DOE), and the Commissariat a l-Energie Atomique (CEA), France a coupled 3-D thermal hydraulics-neutron Kinetics benchmark was defined. The overall objective of OECD-NEA V1000CT reactivity transients where mixing phenomena (mass flow and temperature) in the reactor pressure vessel are complex. Original data from the Kosloduy-6 Nuclear Power Plant are available for the validation of computer codes one experiment of pump start-up (VT1000CT-2). The CEA presented results for the V1000CT-1 Exercise 2 using a coupling of FLICA4(3)and CRONOS2(2) via the coupling tool ISAS(4). The FLICA4-CRONOS2 VVER-1000 model is based on the data available in the benchmark specifications. this paper sensitivity studies and presents the CEA results for V1000CT-1 Exercise 2 as Well as a comparaison sith expereimental results at hot Power Steady State (HP SS)
