PWR has various meanings in the Technology category. Discover the full forms, definitions, and usage contexts of PWR in Technology.
A power reactor in which heat is transferred from the core to an exchanger by high temperature water kept under high pressure in the primary system. Steam is generated in a secondary circuit. Many reactors producing electric power are pressurized water reactors.
TechnologyThe ratio of true power to the apparent power in a circuit, especially those that are not purely resistive. It is also equal to the cosine of the phase angle for the circuit. The rate of producing, transferring, or using energy, most commonly associated with electricity. Power is measured in watts and often expressed in kilowatts (kW) or megawatts (mW).
