Nuclear Reactor Integrated Simulation Project
2009-2012 | European Commission - FP7

The target of the NURISP Collaborative Project was to make new and significant steps towards the NURESIM European Reference Simulation Platform, which is a set of state of the art software devoted to the simulation of normal operation and design basis accidents of light water reactors (BWR, PWR, VVER), while it includes a number of codes covering different physics such as neutronics, thermal-hydraulics, fuel thermo-mechanics, as well as relevant scales, i.e. local (sub-channel or pin), fuel assembly, core and reactor system. During the course of NURISP the codes are extensively benchmarked and validated against experiments, comprising also testing and comparison of different neutron cross-section libraries. The platform is set to provide a more accurate representation of the physical phenomena by developing and incorporating “best estimate” codes, better validated and qualified, faster models in core physics, two-phase thermal-hydraulics and fuel codes.

Major Achievements

The project addressed a wide spectrum of problems. Major Results related to the NCSR Demokritos participation include the extensive qualification of the TRIPOLI-4 Monte-Carlo code using VENUS, a MOx (Mixed Oxide, U-Pu) international benchmark reactor core analyzed with various well-established international neutronics codes using a spectrum of neutron cross section libraries.
