SUBSALS: a subchannel thermal-hydraulic code for IRT type fuel analysis
نویسندگان
چکیده
The LVR-15 research reactor is operated with a tube type fuel IRT-4M. Due to fuel’s unique concentric square annular shape with, coolant flow subject significant pressure driven crossflow. Detailed calculation of such patterns beyond capabilities standard system codes used for the thermal hydraulic safety analysis. To assess core designs consisting IRT-4M assemblies, new subchannel code under development at Research Centre Rež and Czech Technical University in Prague.Computer program SUBSALS single phase, steady state, solver development. Rigid computational mesh describes IRT-like geometries, it also suitable other specific doubly connected ducts.In this contribution, general description procedure presented along code-to-code comparison. It could be as proof concept future improvements calculations reactors.

Recent advances in computational fluid dynamics (CFD) codes along with high performance computing hardware made the codes more useful in many engineering applications. For instance, single-phase CFD codes have long been used to predict the fluid flow in fuel channels of a pressurized water reactor (PWR) [1, 2]. Considering the current affordable number of computation mesh is a little below one ...
