Absolute yield and kinetic parameters of delayed neutrons from the neutron-induced fission of Pu-239
There is currently a strong request, supported by IAEA/Coordinated Research Program, to provide new high quality data of delayed neutron (DN) yield and group constants for nuclear reactor and criticality/safety applications, as well as to validate fission models with calculations like FIFRELIN or GEF. In this proposal, the PF1B instrument is requested to deliver a collimated cold neutron beam to an active target of Pu-239 enclosed in a flat miniature fission chamber. The latter is surrounded by a neutron long counter. A fast shutter (<10ms) will be placed prior to this device, in order to drive repeated cycles of irradation and decay phases. The DN emission will be recorded as well the prompt neutron emission, in parallel with the monitoring of the fission events from the target. This proposal is focused on irradiating a new Pu-239 miniature fission chamber. in addition, a U-235 detector will also be irradiated in the same setup for comparison with results obtained in experiment 3-07-380. This proposal is part of a PhD work by D. Foligno (2016-2019). A financial support was obtained by EDF and FRAMATOME, as well as from the NEEDS/NACRE collaborative program hosted by CNRS.
The data is currently only available to download if you are a member of the proposal team.
