Abstract
A computational CFD model has been developed that makes it possible to determine the scalar values of temperature and vector values of air velocity in the spent nuclear fuel storage (SNFS) at an NPP of the VVER-1200 conceptual design. The calculated values serve as a basis to substantiate safe operation of transport packaging casks (TPCs) with spent nuclear fuel placed in the SNFS and confirm the adequacy of the structural and process solutions adopted in the SNFS design, which ensure the necessary safety and reliability margins without the need to perform expensive full-scale or mock-up experiments.
