ARCHER’s System Code Inventory on track

One of the tasks in ARCHER Subproject 1 is to make an inventory of all the available and currently used High Temperature Reactor (HTR) plant simulation tools in Europe for neutron physics and thermal hydraulics.

For this purpose, the IKE Institute at the University of Stuttgart sent out a questionnaire to collect information on the use and development status of codes used in simulations. Both European and non-European codes are used amongst partners.

This task will help to set the future requirements for the design, performance evaluation, safety and licensing of a nuclear cogeneration demonstration.

An evaluation table was created to organise this information and to facilitate the comparison of the collected data. In addition, IKE used available manuals and published papers to compensate for missing information.

The final table should be helpful for decision-making on which codes to use according to the specific cases. It also provides information on possible coupling to other codes and identifies those that are coupled, their task and the method the coupled codes apply.

A second overview table attempts to classify these codes with respect to their status, i.e. active development or application only; availability of source codes; and background of the information received, whether from user or developer.

This should allow identifying the possible candidate(s) for further development with respect to the missing capabilities needed to close the gap for a comprehensive HTR analysis, including reactor physics, thermal hydraulics for reactor pressure vessels, primary and secondary systems, and containment phenomena along with other features.

The following codes have been listed:

  • European: ASTEC-V2, ATHLET MOD 2.2 Cycle A with DYN3D, ATHLET MOD 2.2 B, CATHARE 2, CRYSTAL, DORT-TD/THERMIX, DYN3D, FPRC, FRESCO/PANAMA, MGT-3D, PANTHERMIX, SIM-ADS, SPECTRA, STACY, TAC-NC, THERMIX-DIREKT, TORT-TD/ATTICA3D, TRAC-AAA, TNT, VSOP, WIMS, ZIRKUS
  • Non-European: ACCORD, CONTAIN, GAMMA+, GOTHIC, FLOWNET, FLOWNEX, MELCOR, RELAP-3D, RELAP-MOD3.2, RELAP-MOD3.3, SCDAP/RELAP/ATHENA, THYDEHTGR, TRAC-M
