Joint Evaluated Fission and Fusion (JEFF) Library version 4.0 test 2
The JEFF-4T2 nuclear data library content has been agreed upon in October 2022. It includes one set of data containing 564 neutron cross section evaluations.
The main changes include:
- New evaluations for the 'Big-3' (U-235, U-238, Pu-239)
- A new Fission Yields evaluation for the thermal neutron induced fission of U-235
- The adoption of the following INDEN evaluations:
- 5-B-10g, 5-B-11g, 8-O-18g, 9-F-19g, 14-Si-28g, 14-Si-29g, 14-Si-30g, 24-Cr-50g, 24-Cr-52g, 24-Cr-53g, 24-Cr-54g, 25-Mn-55g, 26-Fe-54g, 26-Fe-56g, 26-Fe-57g, 29-Cu-63g, 29-Cu-65g
- The Thermal Scattering Law files are the same as JEFF-4T1.
Warning
Please note that this is a test library that has not been approved for formal release. The latest official release remains JEFF-3.3.
