ORILL is a code suite for nuclear research reactors design and operational safety.

  • ORILLCODE: 1D transmutation, fuel depletion, and radiological protection
  • MULTILLABY: multi-compartment model dispersion and transmutation
  • HARMATTILL: atmospheric plume dispersion and radiological consequences

ORILL has been cooked at the Nuclear Safety Unit of the Institut Laue-Langevin (ILL), Grenoble, France. Actually, there is a need for such pocket tools that not addressed by available heavy codes.

The name “ORILL” comes from “ILL” and the prefix “OR” is a tribute to the excellent ORIP_XXI freeware from E.G.Romanov, V.A.Tarasov, F.Z.Vahetov, Research Institute of Atomic Reactors, Dimitrovgrad, Russia.
