OUT OF PILE EXPERIMENTS ON THE INVESTIGATION OF HYDROGEN INTERACTION WITH REDUCED ACTIVATION FERRITIC-MARTENSITIC STEEL F82H

摘要

One of the main concerns of fission and fusion reactors development is the ecological aspect of their operation. If we consider fusion reactor operation with high energy and density neutron fluxes, the problem of activated materials management will be very important. To reduce the level of induced radioactivity it is supposed to use reduced-activation steels, for example F82H steel. Nevertheless the main reason of these steels application is their good stability against swelling and embrittlement. Because of possible application of this steel in the design of DEMO liquid metal blanket it is very important to know the parameters of its interaction with hydrogen isotopes for evaluation of tritium uptake and permeation flux in structural elements made of this material.
