ITER oriented neutronics benchmark experiments on neutron streaming and shutdown dose rate at JET

Abstract

Neutronics benchmark experiments are conducted at JET in the frame of WPJET3 NEXP within EUROfu-sion Consortium for validating the neutronics codes and tools used in ITER nuclear analyses to predictquantities such as the neutron flux along streaming paths and dose rates at the shutdown due to acti-vated components. The preparation of neutron streaming and shutdown dose rate experiments for thefuture Deuterium-Tritium operations (DTE2 campaign) are in progress. This paper summarizes the statusof measurements and analyses in progress in the current Deuterium–Deuterium (DD) campaign and theefforts in preparation for DTE2.
