Boiling water reactor - Wikipedia

A boiling water reactor (BWR) uses demineralized water as a coolant and neutron moderator.Heat is produced by nuclear fission in the reactor core, and this causes the cooling water to boil, producing steam. The steam is directly used to drive a turbine, after which it is cooled in a condenser and converted back to liquid water. This water is then returned to the reactor core, completing the loop.

Boiler - Energy Education

Boilers are used in power plants in order to produce high pressured steam, so that the plant can generate electricity.The process that does this is known as the Rankine cycle.The boiler takes in energy from some form of fuel such as coal, natural gas, or nuclear fuel to heat water into steam.All but a small fraction of the world's primary energy comes from fuels, and about three-quarters of

All boilers require 1L of water per 150L of steam produced. If a boiler runs out of water, and is then fed more water while it is still hot, it will explode, so make sure you've got enough water production for your boilers! 2L of steam makes 1 EU, multiplied by the efficiency loss of the steam turbine. The first set of boilers available are the

The Nuclear Boiler is a machine that is currently used to refine Uranium Hexafluoride from water and Uranium Ore/Yellowcake.. Note that the Chemical Extractor processes one Uranium Ore to three Yellowcake, therefore more Hexafluoride gas is obtained by refining the latter at the expense of time and power.. As of 1.1.4 there is no way to pipe the Uranium Hexafluoride gas, so the Centrifuge must
