Pressurized Water Reactors - Disadvantages

Disadvantages. The coolant water must be highly pressurized to remain liquid at high temperatures. This requires high strength piping and a heavy pressure vessel and hence increases construction costs. The higher pressure can increase the consequences of a loss-of-coolant accident. The reactor pressure vessel is manufactured from ductile steel ...

Pressurized water reactor - PWR - Nuclear Power

Feb 11, 2014 The pressurized water reactor, abbreviated as PWR, is a light water reactor, in which light water (ordinary water) is used as a moderator as well as the reactor coolant. In PWRs, the reactor coolant is maintained under the high pressure (16 MPa) and at normal operation the flow is considered to be single-phase (without boiling). It is the most common …

Jan 06, 2003 A nuclear power plant where heat is drawn from the reactor core via a closed cooling circuit containing water under high pressure (as the name suggests) in order to keep it in a liquid state at high temperatures. The heated primary coolant is itself in turn cooled by passing through a steam generator, exchanging heat with water in a secondary circuit which is then …

Jan 15, 2015 Pressurized water in the primary coolant loop carries the heat to the steam generator. Inside the steam generator, heat from the primary coolant loop vaporizes the water in a secondary loop, producing steam. The steamline directs the steam to the main turbine, causing it to turn the turbine generator, which produces electricity.

O-rings in Pressurized Water Reactor. 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.

The reactor is a steel pressure vessel. The reactor core is 3.5 m high and has a 3 m diameter. This reactor is refueled once a year during reactor shutdown when one-quarter to one-third of the fuel bundles is replaced. Ordinary water is used as both the moderator and the coolant (also referred to as a LWR, light water reactor).
