People Also Ask about

Is PWR or BWR better?

BWRs can prevent the risk of fire and investment cost plus construction times are lower than a PWR, but these advantages do not come with disadvantages. The core of a BWR is less compact and is bigger than a PWR because it requires more control rods and uses four times more fuel elements.

What are the disadvantages of BWR?

Disadvantages of BWR Larger reactor pressure vessel than for a PWR of similar power, with correspondingly higher cost, in particular for older models that still use a main steam generator and associated piping. Contamination of the turbine by short-lived activation products.

How do boiling water reactors work?

Boiling Water Reactors BWRs heat water and produce steam directly inside the reactor vessel. Water is pumped up through the reactor core and heated by fission. Pipes then feed the steam directly to a turbine to produce electricity. The unused steam is then condensed back to water and reused in the heating process.

How does a boiler water reactor work?

Boiling water reactor boils light water that is fed to the reactor. The evaporated steam is then fed directly to the steam turbine. Steam then flows through the steam turbine and is cooled down in the condenser. The water is then pumped back to the cycle by major circulating pump.

What is the principle of boiling water reactor?

Boiling water reactors have a closed water-steam cycle. In the cooling water system, the coolant water flows through the reactor core, where the heat in the fuel elements, produced through nuclear fission, heats the water to around 286 degree Celsius so that it boils in the reactor pressure vessel.

What are the disadvantages of boiling water reactors?

Disadvantages The BWR has negative power demand coefficient. The steam leaving the reactor is slightly radioactive and hence the turbine and the pipings should be properly shielded. Since the boiling of water on the surface of the fuel is allowed, the 'burn out' of fuel is more.

What temperature does a boiling water reactor operate at?

The pressure and temperature in the reactor are maintained near 70 MPa and 286°C. FIGURE 12-9. Boiling water reactor (BWR). The water surrounding the fuel rods in the reactor core of the BWR must be maintained as liquid because the core is designed for water to serve as the neutron moderator.
