Concrete and Stainless Steel Activation/Decay Heat Data for the IFMIF-DONES Test Cell Components

Activity inventories and decay heat for waste evaluation and decommissioning are essential parameters for development of any nuclear device. The activities in this field aim to provide the detailed calculation results and identify the needs for the IFMIF-DONES facility and components. The main objective of the study is to perform activation/decay heat calculations for steel and concrete materials located in Target & Test Cell (TC) of the accelerator. This paper contains the data on updated activation, decay heat and dose rates calculations of TC liner and concrete inside biological shielding walls. On this basis new data was provided for the further DONES (one accelerator, 125 mA current, 5 MW beam power to the target) design, or the need for performing additional activation calculations cases not considered so far. Test Facility consists mainly of two systems: 1) the Test Cell housing the nuclear reaction and 2) the set of hot cells allowing the replacement of the Target Assembly and the TMs, and also the preparation of new modules and the extraction of irradiated specimens. The Test Cell is the system where beams converge with the Li of the Target Assembly to generate high neutron and gamma radiation fields to irradiate Test Modules. Then, high quantity of radioactive materials will be in this cell, as well as liquid metal.
