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...

JOSHUA is a computational system developed to perform the extensive engineering and physics calculations needed in the design and analysis of Savannah River Plant (SRP) nuclear reactors. Application of this system significantly enhanced the efficiency, effectiveness, accuracy, and safety of nuclear reactor design and analysis. The unique features of SRP reactors, which necessitated the Site’s d...

The Experimental Breeder Reactor-II (EBR-II) was a 62.5 MWt±20 MWe sodium cooled fast reactor that was operated successfully for 30 years. Over its period of operation a wealth of fuels and materials information originated from EBR-II. Several missions were conducted in EBR-II, all of which yielded new and valuable additions to the world's knowledge base for nuclear materials. Some of the ®rst ...

The monitoring of detailed 3-Dimensional (3D) core power distribution is a prerequisite for the operation of nuclear power reactors to ensure that various safety limits imposed on the fuel pellets and fuel clad barriers, such as the Local Power Density (LPD) and the Departure from the Nucleate Boiling Ratio (DNBR), are not violated during the reactor’s operation. The LPD and DNBR need to be cal...
