The core shroud in the boiling water reactor (BWR) design and the core barrel in the pressurized water reactor (PWR) design are very similar, in that they are large-diameter, thick-walled cylinders which are largely used to guide the coolant flow through the internals. Looking for Pressurized water reactors? Sales, revenue and prices, power plants, fuel use, stocks, generation, trade, demand & emissions. Pressurized-water reactor (PWR) A common nuclear power reactor design in which very pure water is heated to a very high temperature by fission, kept under high pressure (to prevent it from boiling), and converted to steam by a steam generator (rather than by boiling, as in a boiling-water reactor).The resulting steam is used to drive turbines, which activate generators to produce electrical power.
