INR provides experimental and theoretical investigations in the research field Energy of the German Helmholtz Association of Large Research Centers (HGF). This work is embedded in the research domains fusion technology, nuclear safety research, stationary energy storage devices and direct energy conversion. Key aspects concern

  • Physical modeling of the heat and momentum transport in  thermally highly loaded components,
  • Computing methods, code development, and data for neutronics and reactor-physical applications,
  • Multiphysics and multi-scale coupling methodologies to compute non-linear phenomena in the fields of neutron-physics, thermal-hydraulics, and fluid-structure interaction,
  •  Layout, design, fabrication, and analysis of nuclear components,
  •  Experiments and instrumentation for flows in gas and liquid metal cooled (helium, air, sodium) test modules to determine heat transfer and pressure drops and for direct energy conversion and high temperature heat storage for solar systems.

 

Besides the application oriented work in the frame of national and international co-operations, fundamental research is performed at the INR, where, in particular, students and Ph.D. candidates are integrated. They are supervised individually by dedicated in-house expert teams. Additionally, the INR is active in academic and vocational education. The INR also organizes and contributes to lectures at the university and international events like summer schools on reactor physics (Frederic Joliot / Otto Hahn) and fusion technologies.

 

KIT-INR has a number of facilities available (FUSION and FISSION)  within the scope of the GENTLE project:

  • Gas cooled systems  (L-STAR)
  • Liquid metal operated  loops e.g. KASOLA (Sodium, GaInSn) and measurement techniques
  • Helium and other Pure Gases Loops (Fusion)
    • FLEX (He, 0.4 MPa, 12 g/s)
    • HELOKA-LP (Air, 0.6 MPa, 120 g/s)
    • HELOKA-HP (He, 11 MPa, 1400 g/s
  • KIT-INR is equipped with Multi-scale thermal hydraulic experimental facilities
  • CAD-Office for design of complex systems

 

INR numerical activities are focused on both use of external codes and development of own code.  Hereafter is a list of in-house code developments:

  • Karlsruhe modular neutron physics extendable code system (KANEXT) for reactor simulations
  • Thermal hydraulic sub-channel codes for LWR and fast rector systems: SUBCHANFLOW
  • Porous media two-phase flow code for nuclear and non-nuclear applications (TWOPORFLOW)
  • High-fidelity code system for direct prediction of local safety parameters (DYNSUB)
  • High fidelity Thermal hydraulic /Monte Carlo coupled code system for reference solutions (MCNP5/SUBCHANFLOW)
  • High-fidelity CFD/SP3 transport coupled code NHYSDYN (DYN3D-SP3/NEPTUNEC-CFD)

 

International codes under Validation, improvements and application:

  • CFD codes (NEPTUNE-CFD, ANSYS CFX)
  • Sub-channel codes (FLICA4, Cobra-TF)
  • Thermal hydraulic system codes such as ATHLET (German), RELAP5 (USA), TRACE (USA), ATHLET (Germany)
  • Core simulators: DYN3D (Germany), PARCS (USA), PARTISN (USA)
  • Neutronic Monte Carlo codes: MCNP5 (USA), SERPENT (USA)
  • Uncertainty quantification: SUSA (Germany)

  • Own LINUX computer clusters, access to KIT SCC large computer clusters
  • High Performance Computer Center for Energy
  • Simulation Lab for Nuclear Safety (under implementation)

 

KIT-INR is also equipped with

  • Own LINUX computer clusters, access to KIT SCC large computer clusters
  • High Performance Computer Center for Energy
  • Simulation Lab for Nuclear Safety (under implementation)
