CASMO-3/SIMULATE-3 benchmark on Ringhals units
Validation of the Studsvik Core Management System (Studsvik-CMS) is presented on Ringhals units 2, 3, and 4, Westinghouse three-loop, 157-assembly pressurized water reactors (PWRs) operated by the Swedish State Power Board (SSPB). The work is a part of the project to develop full in-house in-core fuel management (ICFM) capability based on a modern reactor physics methodology. The major codes of Studsvik-CMS are the cell data code CASMO-3 and the advanced nodal code SIMULATE-3. The SSPB has used CASMO-3 since its first reloads for both PWR and boiling water reactor units. The code SIMULATE-3 was recently installed for PWRs to replace conventional nodal core models and to obtain pin-power reconstruction capability. The Ringhals cores have several advanced features that make them especially interesting for testing the accuracy of modern nodal methods. The Ringhals units operate on an annual cycle with summer refueling. The analyzed cycles include base load, load-follow, and coastdown operation.
