Absolute yield and kinetic parameters of delayed neutrons from the neutron-induced fission of 233U
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 U233 in the form of a flat fission chamber. The latter is surrounded by a neutron detector consisting of a cylindrical PE block, with 16 He3 tubes. A fast beam stop system 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 experimental set-up is providing better conditions for DN measurement at very short-time compared to other reported experiments. This proposal is a continuation of a similar proposal dedicated to U235 (3-07-380) and Pu239 (3-07-385). It is financially supported 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.
