Abstract
Polaris is an easy-to-use 2D light-water reactor lattice physics code available within the SCALE code system. Polaris is used to support the confirmatory analysis needs of the US Nuclear Regulatory Com-mission and is used worldwide for both conventional fuel design assessment and accident-tolerant fuel candidate assessment. Since its original release in SCALE 6.2 in 2016, several enhancements have been integrated into Polaris for runtime improvements, extended geometry support, detector response modeling, and new workflows for spent nuclear fuel inventory analysis. This paper summarizes Polaris’s enhancements and new features, which are available in SCALE 6.3 (released in 2022).
