Accurate predictions of material inventories is a key input to virtually all aspects of the operation, safety and environmental assessment of nuclear plants. Additionally, the neutron-induced transmutation (change) of material composition (inventory) with time, and the creation and evolution of configurational damage from atomic displacements, require precise quantification because they can lead to a change in material properties, and thus influence reactor-component lifetime. This report provides a detailed and comprehensive set of data concerning the activation, transmutation (depletion and build-up) response, and immediate damage response under neutron irradiation of all naturally occurring elements from hydrogen to bismuth, as well as the material alloys that are used to model ITER for nuclear analysis. Whilst the goal of this ‘handbook’ is to provide a global picture of the response of a material, covering the majority of nuclear technological space, special focus is given to the in-vessel conditions predicted for the ITER experimental fusion reactor, which is currently being built in France via a global partnership of research organisations. Results are presented from simulations with the inventory code FISPACT-II using the latest version of the TENDL nuclear data libraries – TENDL-2015.
