S5K leverages the power of SIMULATE, the industry standard in nodal reactor analysis. Including cutting-edge neutronic methods and advanced engineering features, S5K delivers unparalleled fidelity with production-level run times.
S3K solves the transient three-dimensional, two-group neutron diffusion equations, including a six-group model for delayed neutron precursors. Intranodal flux and power distributions within each node are used to compute the power, fuel temperatures, and enthalpies for every axial level of every fuel pin in the core during transients.
Each fuel assembly in the core is explicitly represented in the core thermal-hydraulics. For BWR operational transients, vessel and steam line models are capable of simulating acoustic effects in the steam line due to sudden valve closures or openings.
