Neutron flux characterisation of MEGAPIE target

The neutronic performances of the MEGAPIE target will be studied using fission micro-chambers specially designed to stand the severe irradiation conditions of flux and temperature. The absolute neutron flux will be monitored on-line at different positions inside the target in order to studied its sp...

Description
Summary:The neutronic performances of the MEGAPIE target will be studied using fission micro-chambers specially designed to stand the severe irradiation conditions of flux and temperature. The absolute neutron flux will be monitored on-line at different positions inside the target in order to studied its spatial and temporal variations. Together with the flux characterisation, actinide incineration potential of such target will be study through 241Am and 237Np isotopes. Prototype fission detectors and electronics have been successfully tested during the past three years at the High Flux Reactor of Laue Langevin Institute. The results of these tests are presented.
