Natural Uranium being a limited resource on earth needs to be conserved and utilized optimally when used in the reactor core. Pressurized heavy water reactors (PHWRs) are fueled with natural Uranium (NU) in the form of short length bundles. Features like online refueling and short length ...
Pressurized heavy water reactors (PHWRs) are in many ways similar to pressurized water reactors (PWRs) in the sense that a pressurized coolant is pumped through a reactor core, being heated by the nuclear fuel assemblies in the core. The coolant then flows through the tube bundle of steam ge...

The primary objective of the ORNL pressurized-thermal-shock (PTS) experiments is to verify analytical methods that are used to predict the behavior of pressurized-water-reactor vessels under these accident conditions involving combined pressure and thermal loading. The criteria on which the experiments ...
Nuclear reactors employ a reactor core comprising a mass of fissile material, such as a material containing uranium oxide (UO2) that is enriched in the fissile235U isotope. A primary coolant, such as light water or heavy water flows through the reactor core to extract heat for use in heating...
However, the design and construction of such reactors, which are different from pressurized water reactors of conventional type, can lead to additional costs and technical difficulties in the drawing up of an equipment schedule in nuclear power stations. ...
