Recent nuclear data libraries, including both ENDF/B-VIII.0 and the new ENDF/B-VIII.1 release, have included a significantly larger number of thermal scattering law (TSL) files than have previous data releases.  This leaves many nuclear criticality safety (NCS) practitioners in the difficult position of selecting TSL files to use in their models without sufficient knowledge, training, or expertise to make informed, physics-based decisions about the appropriateness of the TSL files to their specific applications. This workshop will help bridge the gap by providing the necessary information for NCS practitioners to perform their analysis not just for these libraries, but for any TSL materials in future nuclear data library releases.

This workshop will be broken up into two sections. First, a theory section that will go over: what TSLs are/aren’t, how they’re used in transport codes, and how they should be used in criticality safety applications. Second, there will be a series of practical exercises that will demonstrate the points discussed in the theory section. These practical exercises will be made to ensure that they cover several of the more prominent neutron transport codes used in the international NCS community: SCALE, MCNP, and SERPENT.

Users will be expected to arrive with their own computers or laptops with the codes pre-installed on them. As such, the only prerequisite will be having a working version of the codes installed on their machines. Specifically, the inputs will be designed & optimized to work on SCALE6.3.1, MCNP6.3, and SERPENT2.2. These codes are only required for participation in the practical exercises during the workshop. Attendees are not required to participate in these exercises, and are therefore not required to have a license for these codes to attend. There are no citizenship restrictions.
