A Process Inherent Ultimate Safety Boiling Water Reactor

A lattice Boltzmann framework to simulate boiling water reactor core hydrodynamics

This paper presents a consistent LBM formulation for the simulation of a two-phase water–steam system. Results of initial model validation in a range of thermodynamic conditions typical for BoilingWater Reactors (BWRs) are also shown. The interface between the two coexisting phases is captured from the dynamics of the model itself, i.e., no interface tracking is needed. The model is based on th...

Advanced Power Plant Modeling with Applications to an Advanced Boiling Water Reactor and a Heat Exchanger

Advanced methods that use continuity wave equations in fluid flow paths and exact solutions of these and all other differential equations are applied to transient performance models of a counter flow heat exchanger and an Advanced Boiling Water Reactor (ABWR). The continuity wave equations for single and two-phase flow, with heat addition, are developed, and the exact solution for a typical lea...

REACTOR PHYSICS CALCULATIONS ON MOX FUEL IN BOILING WATER REACTORS (BWRs)

The loading of MOX (Mixed Oxide) fuel in BWRs (Boiling Water Reactors) is considered in this paper in a “once-through” strategy. The fuel assemblies are of the General Electric 8×8 type, whereas the reactor is of the General Electric BWR/6 type. Comparisons with traditional UOX (Uranium Oxide) fuel assemblies revealed that the loading of MOX fuel in BWRs is possible, but this type of fuel creat...
