Pressurized heavy-water reactor

A pressurized heavy-water reactor or pressurized heavy toilets reactor ( PHWR ) is a Nuclear reactor which uses combustible Uranium natural like and of the heavy Eau (D₂O) like coolant. Heavy water is maintained under pressure until its Dewpoint, which makes it possible to reach higher temperatures and thus to transport more Chaleur apart from the heart of the engine. Although heavy water is relatively expensive, the engine can function without calling upon expensive equipment of Uranium enrichment, which minimizes the costs.

The first PHWR were the engines CANDU, engines of Canadian design manufactured by the company AECL. After being sold in the whole world, approximately 29 are currently under operation or restoration. The Indian nuclear company NPCIL built and exploits 11 engines PHWR. In the beginning, these engines manufactured apart from Canada were Retro-engineering engine CANDU, but the current models have specific characteristics.
