“…Considering the adopted method for calculating these quantities (SLBW), FRENDY’s default package offers the calculation of cross-sections for two important elements: Plutonium 238 and Technetium 99. The former element (Pu238) is of crucial importance, for instance, to space exploration [ 37 ] and Mars colonization [ 38 , 39 ]. In addition, 80% of the scans performed in nuclear medicine departments are made from the latter element [ 40 ].…”

In the last seven years, Kaniadakis statistics, or κ-statistics, have been applied in reactor physics to obtain generalized nuclear data, which can encompass, for instance, situations that lie outside thermal equilibrium. In this sense, numerical and analytical solutions were developed for the Doppler broadening function using the κ-statistics. However, the accuracy and robustness of the developed solutions contemplating the κ distribution can only be appropriately verified if applied inside an official nuclear data processing code to calculate neutron cross-sections. Hence, the present work inserts an analytical solution for the deformed Doppler broadening cross-section inside the nuclear data processing code FRENDY, developed by the Japan Atomic Energy Agency. To do that, we applied a new computational method called the Faddeeva package, developed by MIT, to calculate error functions present in the analytical function. With this deformed solution inserted in the code, we were able to calculate, for the first time, deformed radiative capture cross-section data for four different nuclides. The usage of the Faddeeva package brought more accurate results when compared to other standard packages, reducing the percentage errors in the tail zone in relation to the numerical solution. The deformed cross-section data agreed with the expected behavior compared to the Maxwell–Boltzmann.

“…Recovery of the minor actinides (Am, Cm, Np) from nuclear waste has immense relevance for the waste management and application of some of these actinides in thermo-electric devices. [1][2][3] A number of extractants have been developed over the years for the extraction of the minor actinides from the high level nuclear waste (HLW). 1,4,5 Diglycolamide (DGA) derivatives are a promising class of ligands for the co-extraction of the trivalent actinides and lanthanides.…”
