Recent progress in the modelling of helium and tritium behaviour in irradiated beryllium pebbles

Autor: A. Cardella, Claudio Ronchi, E. Rabaglino

Publikováno v: Fusion Engineering and Design. 69:455-461

One of the key issues of the European Helium Cooled Pebble Bed blanket is the behaviour under irradiation of beryllium pebbles, which have the function of neutron multiplier. An intense production of helium occurs in-pile, as well as a non negligible

Study by microtomography of 3D porosity networks in irradiated beryllium

Autor: E Boller, C. Ferrero, Thierry Wiss, Claudio Ronchi, José Baruchel, A. Elmoutaouakkil, E. Rabaglino

Publikováno v: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. 200:352-357

The analysis of gas release modes from irradiated materials during out-of-pile temperature transients and of the related microstructure evolution provides fundamental evidence for developing and validating models of the behaviour of gases in solids.

Helium and tritium kinetics in irradiated beryllium pebbles

Autor: J.-P. Hiernaut, Claudio Ronchi, E. Rabaglino, F. Scaffidi-Argentina

Publikováno v: Journal of Nuclear Materials. :1424-1429

High-precision measurements of the release rate of helium and tritium from weakly irradiated beryllium pebbles were carried out by means of a Knudsen-cell technique. The samples were heated in a high vacuum to temperatures above the melting point and

Study of the microstructure of neutron irradiated beryllium for the validation of the ANFIBE code

Autor: E. Rabaglino, T Schulenberg, Claudio Ferrero, J Reimann, Claudio Ronchi

Publikováno v: Fusion Engineering and Design. :769-773

The behaviour of beryllium under fast neutron irradiation is a key issue of the helium cooled pebble bed tritium breeding blanket, due to the production of large quantities of helium and of a non-negligible amount of tritium. To optimise the design,
