A MIXED CORE FOR SUPERCRITICAL WATER-COOLED REACTORS

Supercritical Water-cooled Nuclear Reactors: Review and Status

Modern concepts of nuclear reactors cooled with supercritical water are presented together with a short history. The supercritical water-cooled CANDU ((CANada Deuterium Uranium) is a registered trademark of AECL) reactor concept is fully discussed. Also, thermophysical properties at critical and supercritical pressures as well as heat transfer and hydraulic resistance at these conditions are pr...

Large Eddy Simulation in Pebble Bed Gas Cooled Core Reactors

A High Temperature Gas-cooled Reactor (HTGR) is one of the renewed reactor designs to play a role in nuclear power generation. This reactor design concept is currently under consideration and development worldwide. The combination of coated particle fuel, inert helium gas as coolant and graphite moderated reactor makes possible to operate at high temperature yielding a high efficiency. In this ...

A Characteristics-based Implicit Finite- Difference Scheme for the Analysis of Instability in Water Cooled Reactors

Two-phase flow systems are prone to dynamic and static instabilities of many kinds. In the last few decades, a considerable amount of work on the two-phase flow instability has been carried out all over the world. Several numerical, experimental and analytical studies were conducted to understand two-phase flow instabilities and to derive the stability criteria. Theoretical modelling of density...
