Simulation of Bundle Test Quench-12 With Integral Code MELCOR
NURETH-14 - 2011 September 25-30
Jiri Duspiva (Nuclear Research Institute Rez plc.)
The past NRI analyses cover the Quench-01, Quench-03 and Quench-06 with version MELCOR 1.8.5 (including reflood model), and Quench-01 and Quench-11 tests with the latest version MELCOR 1.8.6. The Quench-12 test is specific, because it has different bundle configuration related to the VVER bundle configuration with hexagonal grid of pins and also used E110 cladding material. Specificity of Quench-12 test is also in the used material of fuel rod cladding – E110. The test specificities are a reason for the highest concern, because the VVER reactors are operated in theCzechRepublic. The new input model was developed with the taking into account all experience from previous simulations of the Quench bundle tests. The recent version MELCOR 1.8.6 YU_2911 was used for the simulation with slightly modified ELHEAT package. Sensitivity studies on input parameters and oxidation kinetics were performed.
