Neutron-induced fission cross section of 240Pu from 0.5 MeV to 3 MeV
240Pu has recently been pointed out by a sensitivity study of the Organization for Economic Cooperation and Development (OECD) Nuclear Energy Agency (NEA) to be one of the isotopes whose fission cross section lacks accuracy to meet the upcoming needs for the future generation of nuclear power plants (GEN-IV). In the High Priority Request List (HPRL) of the OECD, it is suggested that the knowled...
متن کاملTowards high accurate neutron-induced fission cross sections of 240,242Pu: Spontaneous fission half-lives
Fast spectrum neutron-induced fission cross sections of transuranic isotopes are being of special demand in order to provide accurate data for the new GEN-IV nuclear power plants. To minimize the uncertainties on these measurements accurate data on spontaneous fission half-lives and detector efficiencies are a key point. High -active actinides need special attention since the misinterpretation ...
متن کاملSimultaneous measurement of the neutron capture and fission yields of 233 U
We have measured the neutron capture and fission cross section of 233U at the neutron time-of-flight facility n TOF at CERN in the energy range from 1 eV to 1 MeV with high accuracy by using a high performance 4π BaF2 Total Absorption Calorimeter (TAC) as a detection device. The method, based on the TAC energy response study, allowing to disentangle between γ’s originating from fission and capt...
متن کاملCold-fission yields at effective excitation energies.
The experimental cold-fission yields for the systein 2 3 ' ~ ( n , h , f ) are analyzed as function of the effective total excitation energy (TXE). The nuclear level density effect is taken into account at higher TXE, in order to benefit by the lower experimental data uncertainty as well as to avoid the quantitative account of the level densities close to fragment ground states. In this way the...
متن کاملNeutron - induced fission cross - section of 233 U in the energy range 0 . 5 < En < 20 MeV The n TOF
The neutron-induced fission cross-section of U has been measured at the CERN n TOF facility relative to the standard fission cross-section of U between 0.5 and 20MeV. The experiment was performed with a fast ionization chamber for the detection of the fission fragments and to discriminate against α-particles from the natural radioactivity of the samples. The high instantaneous flux and the low ...
