STARS MSc Project 1
Development of Accident Tolerant Fuel Models in FALCON
FALCON is a state-of-the-art FEM Code for Fuel Performance developed by EPRI in
collaboration with PSI/STARS Designed primarily for thermo-mechanical analyses of current UO2/Zr-Clad technology
New Claddings (SiC) and Fuel Materials (U2Si2) on the way for stronger accident-resistance
Master Project Development of U3Si2 / SiC Thermal-Behaviour Models for FALCON including literature surveys
Verification and/or Validation against available Experimental Data
Assessment of Performance during Normal Operation and Transients for LWRs
Complex Phenomenology of
UO2/Zr Fuel Behaviour Trends towards
Development of New ATF Materials

STARS MSc Project 2
Background Methodology for MCNP Criticality Safety Evaluations with Nuclear Data Uncertainty Quantification (NUSS)
developed at PSI
Validation based on fresh fuel critical experiments only – Applicability for burned fuel need to be proven
Also, account of correlations between experiments could potentially reduce calculated unceratinties
Master Project Review criticality benchmarks suitable for transposition to validation of CSE with Burnup Credit (BUC)
Development of MCNP models and analyses with NUSS using latest libraries
Derive correlations between validation benchmarks and selected application case (e.g. disposal canister)
Evaluate effect of correlations on CSE unceratinties and upper sub-criticality limits
Criticality Safety for Spent Fuel Geological Disposal

SACRE Overview
Panorama – from Core Degradation to Source Term
2018.05.18/LRT /FH41 ( 9 / 12 )
MELCOR is an integral computer code developed by the Sandia National Laboratories for
modeling severe accidents in nuclear power plants. Since the code version 2.1, also accident scenarios in High Temperature Gas-cooled Reactors (HTGRs)
can be considered.
Master Project Improvement of the existing MELCOR input deck of the HTR-PM pebble bed reactor
Investigation on the capabilities to model fission product release and transport in HTR-PM in normal
operation and in accident conditions using the MELCOR core.
Contact: Jarmo ( [email protected] )
Accident Analysis of High Temperature Reactors Estimation with MELCOR of the source term from different severe accident sequences

TEG Overview
2018.05.18/LRT /FH41 ( 11 / 12 )
Background Aerosol Release during Severe Accident in Nuclear Power Plants
Current Techniques and Technology for Measuring Aerosol Characteristics limited
Master Project Develop an optical method based on light attenuation
Design and conduct experiments in a smaller scale facility using LINX infrastructure, where analytical
models from literature can be used to analyze the experiments, e.g. particle settling in a quiescent fluid.
Comparison against established techniques such as Phase Doppler Anemometry (PDA) or Shadowgraphy
Expected outcome: A scalable aerosol measurement method
