Abstract
Nuclear fission yields data measurements for thermal neutron induced fission of 241Pu have been carried out at the ILL in Grenoble, using the Lohengrin mass spectrometer. The relative isotopic yields for the masses 137 up to 141 have been derived with the associated experimental covariance matrices. Moreover, from preliminary results for the masses 92, 138 and 139, a clear evolution over fission product kinetic energy of the isotopic total count rate is observed.
Highlights
The isotopic fission product yield, Y(A, Z), is the production rate by fission of a specific nucleus of mass A and nuclear charge Z
A collaboration of the LPSC, the CEA and the Institut Laue-Langevin (ILL) focuses on producing precise measurement of fission yields for major actinides with the related experimental variance-covariances matrices [6]
Focus will be given to the 241Pu thermal neutron induced fission isotopic yields
Summary
The isotopic fission product yield, Y(A, Z), is the production rate by fission of a specific nucleus of mass A and nuclear charge Z. The fission product yields knowledge for thermal neutron induced fission, condensed in the recent evaluated nuclear data libraries The uncertainty propagation can not be properly done since the yields variance-covariance matrices are missing from the evaluated data libraries, despite recent efforts to tackle this issue [2][3][4][5]. Some discrepancies between the major libraries exist and need to be understood. For these reasons, a collaboration of the LPSC, the CEA and the ILL focuses on producing precise measurement of fission yields for major actinides with the related experimental variance-covariances matrices [6]. Focus will be given to the 241Pu thermal neutron induced fission isotopic yields. The main results will be displayed and discussed in the last section, Sect. 4
