Fusion materials irradiation test facility: description and status
The Fusion Materials Irradiation Test (FMIT) Facility will generate a high-flux, high-energy neutron source that will provide a fusion-like radiation environment for fusion reactor materials development. The neutrons will be produced in a nuclear stripping reaction by impinging a 35 MeV beam of deuterons from an Alvarez-type linear accelerator on a flowing lithium target. The target will be located in a test cell which will provide an irradiation volume of over 750l within which 10 cm/sup 3/ will have an average neutron flux of greater than 1.4 x 10/sup 15/ n/cm/sup 2/-s and 500 cm/sup 3/ an average flux of greater than 2.2 by 10/sup 14/ n/cm/sup 2 -/s with an expected availability factor greater than 65%. The projected fluence within the 10 cm/sup 3/ high flux region of FMIT will effect damage upon the materials test specimens to 30 dpa (displacements per atom) for each 90 day irradiation period. This irradiation flux volume will be at least 500 times larger than that of any other facility with comparable neutron energy and will fully meet the fusion materials damage research objective of 100 dpa within three years for the first round of tests.
