50. Analysis of fuel rod behavior during design basis accidents using the Bison code

Giovanni Pastore (Idaho National Laboratory)

The US Department of Energy (DOE) has been developing state-of-the-art capabilities to simulate nuclear fuel behavior within the Consortium for Advanced Simulation of Light Water Reactors (CASL) and Nuclear Energy Advanced Modeling and Simulation (NEAMS) programs. The result is the Bison code [1], a modern multidimensional, finite-element based fuel performance code developed at Idaho National...

37. A burn-up module for application in fuel performance codes: methodology, verification and assessment for MOX fuel in thermal and fast neutron spectra

The evolution of actinides within the nuclear fuel affects the power distribution and the thermal and mechanical material properties. In addition, the concomitant production of helium in the fuel matrix due to actinide alpha decays and nuclear reactions has a relevant impact on the whole fuel rod performance, since helium concurs to fuel gaseous swelling and gas release. For this reason, fuel...

33. PLEIADES ALCYONE 3.5D simulation of a power ramp including OpenCalphad fuel thermochemistry with TAF-ID

Clément Introïni (Commissariat à l'Energie Atomique et aux énergies alternatives)

ALCYONE 2.1 fuel performance code, co-developed by CEA, EDF and Framatome within the PLEIADES software environment, provides a multidimensional modeling for detailed analysis of PWR fuel elements behavior under irradiation [1]. ALCYONE is validated by comparing numerical results to post-irradiation examinations from a large experimental database. Iodine-Stress Corrosion Cracking is one of the...

20. Multi-scale nuclear fuel simulation with VER software

Marcelle Ibrahim (CEA)

PLEIADES is a scientific code platform dedicated to nuclear fuel
behaviour simulation for several types of reactors: water cooled
reactors, sodium cooled fast reactors, research and material testing
reactors, etc. In this platform, the microstructures of these
different types of fuel are studied using VER software (Representative
Elementary Volume). These studies aim at the comprehension of...
