  1. MULTIFACTORIAL MODELS FOR HEATCONDUCTION AND HIGH-TECH WAYS TO PROTECT FISSION MATERIALS Saenko A.V. Obninsk State Technical University for Nuclear Power Engineering, Obninsk, Russia

  2. MULTIPLE FACTOR ANALYSIS OF THE MODEL OF THE SPHERICALLY-SYMMETRIC DEVICE WITH FUEL ELEMENT Structure of the bundled software and geometric configuration for three technology of device

  3. LINEAR MODELS (BM, MHR, MRB, MRF, MEI) NON-LINEAR MODELS(RNM, CNM, CNR) Heat conduction equation for heat-generating sphere: Solution of equation: Heat conduction equations forshells: Solutions of equations: Boundary conditions: Continuity conditions:

  4. VISUALIZATION OFTHE SOLUTION The temperature profiles (content of238Pu 5.5%) MHR CNM CNR MRF The dot-line are the temperature profiles for BM. Profiles for «High Technology» is low for 50 оС

  5. THE MODEL WITH EXTERNAL INFLUENCE The model of device with rods Effective heat conductivity coefficient for IV shell: εiis defined for every parts as: n=20 LowTechnology The temperature profiles (content of238Pu 5.5%)

  6. THE ADVICE TOCHANGETHE CONTENT OF238Pu Correction for the content of 238Pu (in %)

  7. STRUCTURE OF THE BUNDLED SOFTWARE

  8. The bundled software was created for estimate thermal field in spherically symmetric device with fuel element. Temperature profiles were obtained for 8 models for two types of the boundary problem and three technologies. Correction for the content of 238Pu were calculated. conclusion
