CASMO-5M is an extended version of Studsvik Scanpdower's newest lattice code, CASMO-5. While CASMO-5 is used primarily for generation of data for the downstream CMS codes (e.g., SIMULATE-4, S3K, etc.) CASMO-5M is designed for application to standalone lattice analysis calculations.
These include multi-assembly configurations which can be used for example to validate the nodal model. Or can be combined with modeling of fuel storage pool modeling. Depleted lattices from single assembly calculations can be combined for example to analyze fuel burnup credit.
