Review of European Thermal-Hydraulic Calculational Methods for Thermal Reactors
Nuclear Science and Engineering, 1988During the past few years, there has been an increasing effort to understand the behavior of nuclear power plants (NPPs) in normal and abnormal situations. To achieve this goal, large computer codes that allow the description of two-phase flows with sources and sinks of mass and heat have been built in many countries.

3D thermal-hydraulic calculations of a modular block-type HTR core
Nuclear Engineering and Design, 2006Abstract This paper deals with 3D numerical simulation of assemblies of a high temperature helium cooled reactor core. The present aim is to investigate an emergency situation due to the blocking of few Helium channels in the core. In this situation, some Helium channels for coolant passage are blocked and the related issue is the temperature ...

Liquid-Metal-Cooled Reactor Thermal-Hydraulic Calculations in the United States
Nuclear Science and Engineering, 1988A wide range of thermal-hydraulic computer codes has been developed by various organizations in the United States. These codes cover an extensive range of purposes from within-assembly-wise pin temperature calculations to plantwide transient analysis. The codes are used for static analysis, analysis of protected anticipated transients, and analysis of ...
