Pressure Water Regulator (PWR) – Pros and Cons
Pressure Water Regulator (PWR):
It is a hot reactor, using enriched uranium oxide, coated with zircalloy as fuel. A PWR has a fuel assembly of 200-300 rods each, arranged horizontally in the core, and a large reactor will have around 150-250 fuel rods containing 80-100 tons of uranium. Steel is used for pressure work. Pressurized water is used both as a heat transfer fluid and as a moderator. It is surrounded by pressure vessels and water heaters. In this reactor, Frontier Utilities Rates high boiling water is prevented because the water is pressurized to about 150 atmospheres. The hot water from the reactor flows to a reheater (or generator) where its heat is transferred to the feed water to produce steam. The second air conditioner works at low pressure. The main coolant then comes from the heat exchanger and the main circulation pump which delivers it to the reactor. The …
