    Calculations of radioactive inventories in fission reactor components for decommissioning purposes were reviewed at the International Atomic Energy Agency (IAEA) Advisory Group Meeting on “Nuclear Data Required for Fission Reactor Decommissioning” in Vienna, September 1992. Details of neutron transport calculations through pressure vessel and bioshield necessary to determine fluxes and spectra at these locations were discussed. In contrast to embrittlement studies the main interest for this problem is in accurate description of transport of thermal neutrons. The codes and data libraries used by the specialists in this field were identified. Actions necessary to improve the accuracy were agreed upon. Procedures for calculating activation of materials in reactor components were also assessed. The need for compilation of a special data library and a benchmark testing of libraries together with available codes against an experimentally measured data for a real plant at the decommissioning stage was established. Phase 1 of such a benchmark exercise is now under preparation at the IAEA.
