SCALE is a comprehensive modeling and simulation suite for nuclear safety analysis and design developed and maintained by Oak Ridge National Laboratory under contract with the U.S. Nuclear Regulatory Commission, U.S. Department of Energy, and the National Nuclear Security Administration to perform reactor physics, criticality safety, radiation shielding, and spent fuel characterization for nuclear facilities and transportation/storage package designs.
The SCALE 6.2.4 validation report four-volume set is now available on OSTI:
- SCALE 6.2.4: Validation Overview
- SCALE 6.2.4 Validation: Nuclear Criticality Safety
- SCALE 6.2.4 Validation: Reactor Physics
- SCALE 6.2.4 Validation: Radiation Shielding
The SCALE 6.3.0 validation reports will be released in 2023 with an additional volume specifically for spent fuel inventory and decay heat (Spent Fuel Applications) and additional Polaris and PARCS LWR validation in the Reactor Physics volume.
The SCALE 6.3 Online Manual is now available.
The 7th SCALE Users’ Group Workshop (hybrid event) was held April 26-28, 2023. For more information about the workshop, please click here.
