A coordination meeting for participants in the Hydrogen Permeation CRP, including a session on the experimental round-robin exercise on irradiated tungsten. This event was held as a hybrid online / in person meeting in Room M0E79 at IAEA Headquarters in Vienna from 4 – 6 October 2021. The Scientific Secretary is Kalle Heinola.
The meeting focuses on the provision of fundamental and evaluated data on hydrogen isotopes permeation in nuclear fusion in-vessel materials and components. It is of crucial importance to know the behaviour of the fusion reactor wall materials with respect to permeation of hydrogen isotopes from the plasma in order to assess their suitability for fuel recycling during plasma operations and isolating the T fuel from the surrounding fusion reactor components. Of particular concern is the trapping and retention of T in the wall components, and the possibility of T diffusing through the material and finding its way into the coolant water of the reactor components, where it would pose a potentially serious radiological hazard for the operating personnel and the environment. Study of hydrogen permeation in the first wall plasma-facing materials is further complicated by the elevated temperatures present under normal operation of a reactor and the anticipated damage they will suffer due to plasma-surface interactions and irradiation-induced damage by the flux of energetic 14 MeV neutrons produced in the D-T fusion reactions.
