SCALE Developments for the U.S. Nuclear Criticality Safety Program: Recent Achievements and Outlook

Research output: Contribution to journalConference articlepeer-review

Abstract

This summary covers the key capabilities in SCALE for NCS practitioners with a focus on those capabilities developed in 2023 and 2024 that support the US Nuclear Criticality Safety Program. SCALE 6.3, released in 2023, is the current, quality-assured production version of the code, intended for use in applications such as criticality safety, validation basis assessment, and uncertainty propagation. All SCALE training is now using the 6.3 series, which is currently planned to be supported with maintenance updates (which include visualization improvements) and bug fixes through 2026. The next series, SCALE 7.0, is currently available as a pre-release beta, with new NCS-facing features focusing on ease-of-use and deployment with parallelism, additional sensitivity and uncertainty capabilities, visualization, and additional post-processing capabilities.
