From “Turbine to Pellet” Integral LWR Safety Analyses

Scope

STARS aims at nuclear reactor modelling and simulations with focus on

Safety assessments for the current generation (GII) of Light-Water-Reactors (LWRs) in general and for the Swiss operating LWRs in particular
Safety evaluations for next-generation LWRs (GIII/GIII+)
The keywords of STARS are LWR nuclear engineering, science and technology.

Technical Areas

STARS is constituted by the three LWR modelling-related research groups of the LRS and the main technical areas of expertise are therefore

Plant Behaviour
(system thermal-hydraulics and fluid dynamics)
Core Physics
(neutronics/radiation transport, reactor physics, and coupled core statics/dynamics)
Fuel Modelling
(fuel thermo-mechanics and material behaviour)

The principle of STARS is to combine these competences and build an advanced
"Turbine-to-Pellet" modeling capability for integral safety assessments of nuclear reactors.

Range of Application

The STARS modelling and simulation activities are currently aimed at covering the following range of applications

Steady-State Normal Reactor Operation
Transients and Dynamical Events
Design-Basis-Accidents
Beyond-Design-Basis-Accidents
(excluding core melt and severe accidents)
Out-of-Core Applications
(Fluence, Activation, Shielding, Spent Fuel Characterization, Criticality Safety w/o Burnup Credit)
