Uses of pressurized nuclear Reactor
Answers
The pressurized water reactor (PWR) is a type of nuclear reactor used to the generate electricity and propel nuclear submarines and naval vessels. They make use of light water (ordinary water, as opposed to heavy water) as their coolant and neutron moderator. It is one of three types of light water reactors, with the others being the boiling water reactor and the supercritical water cooled reactor.
It was originally designed for the U.S. Navy, however, it quickly grew to become the most widely used reactor in nuclear power plants; with 297 in operation around the world as of 2018. This makes them by far the most dominantly used reactor in the world, with the second most (the boiling water reactor) having only 80 in operation. Construction of PWRs diminished greatly after the Three Mile Island nuclear accident, mainly as a result of public support becoming weaker.
Their use on naval vessels and nuclear ships are of extreme importance to various militaries around the world.Nuclear power has a huge advantage over fuels like gasoline or diesel as it allows ships to run for very long periods without the need to refuel. PWRs make a good reactor for these ships since they have a high specific power (high power for their mass) due to their use of high pressure. This allows the reactors to be fairly compact, especially with the use of highly enriched uranium.
