Topics of internship:
Reliability Analyses of a Passive Emergency Core
Cooling System
There are no publications, but they will be
written in the next few months.
3
The research perform the reliability analysis of
passive ECCS using a three-dimensional thermalhydraulic model of the reactor core. The 3D
model will be implemented into a CFD code
(OpenFOAM) using a porous media approach
with distributed heat sources. A new model will
be used to calculate the fuel and clad
temperature in the core.
4
Main steps in the internship plan:
• literature study on new reactor designs with
passive ECCS, reliability study of passive systems,
methods of analysis of passive systems, methods
of uncertainty analyses for passive systems
• performance of the analytical model
• development of porous media CFD model of a
reactor core, including heat sources due to decay
heat
• development of a model to calculate the local
effective clad temperature
