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) %G English %2 https://cea.hal.science/cea-02356018/document %2 https://cea.hal.science/cea-02356018/file/200600005016.pdf %L cea-02356018 %U https://cea.hal.science/cea-02356018 %~ CEA %~ DEN %~ DEN-SACLAY
