    One of the many uses of boiler feed pumps is as part of a Pressurized Water Reactor (PWR) system in nuclear power plants. In a PWR, the primary coolant (superheated water) is pumped under high pressure to the reactor core. The heated water then transfers thermal energy to a steam generator.

    Difference Between PWR and BWR - Pressurized Water Reactor

    Oct 14, 2019· Here the water in the primary loop is maintained at high pressure (15 – 17 MPa) to avoid boiling at reactor exit. Here water pressure remains comparatively low (7 – 8 MPa) as it is allowed to boil. A pressurizer is required to use mandatorily to maintain water pressure in such a way that it does not evaporate even at very high temperature.

    A boiling water reactor (BWR) is a type of light water nuclear reactor used for the generation of electrical power. It is the second most common type of electricity-generating nuclear reactor after the pressurized water reactor (PWR), which is also a type of light water nuclear reactor. The main difference between a BWR and PWR is that in a BWR, the reactor core heats water, which turns to

    What is the safe pressure for a hot-water-heating system?

    Jan 19, 2015· The water pressure in a hydronic boiler shouldn't be over 12- to 15-psi. It should have only enough pressure to raise the water a few feet above the top of the highest point in the piping system. A 12-psi setting will lift water 28' above the fill valve. A 15-psi setting will lift the water to 34'.
