What properties does Magnox have?

Magnox is short for Magnesium non-oxidising. This material has the advantage of a low neutron capture cross-section, but has two major disadvantages: It limits the maximum temperature, and hence the thermal efficiency, of the plant. It reacts with water, preventing long-term storage of spent fuel under water.

Why is AGR reactor core size greater than PWR?

However the reactor core has to be larger for the same power output, and the fuel burnup of 27,000 MW(th) days per ton at discharge is lower than the 40,000 MW(th) days per ton of PWRs so the fuel is used less efficiently, countering the thermal efficiency advantage.

Which gas is used in gas-cooled reactor?

Gas-cooled reactors use graphite as a neutron moderator and carbon dioxide gas as the coolant.

Is Magnox a government?

Magnox Ltd is a nuclear decommissioning Site Licence Company (SLC) under the Nuclear Decommissioning Authority (NDA), a government body set up specifically to deal with the nuclear legacy under the Energy Act 2004.

What kind of fuel does the Magnox reactor use?

The efficiency of graphite as a moderator allows the Magnox to run using natural uranium fuel, in contrast with the more common commercial light-water reactor which requires slightly enriched uranium.

How did the Magnox nuclear power plant get its name?

Magnox. Magnox is a type of nuclear power/production reactor that was designed to run on natural uranium with graphite as the moderator and carbon dioxide gas as the heat exchange coolant. It belongs to the wider class of gas cooled reactors. The name comes from the magnesium – aluminium alloy used to clad the fuel rods inside…

Can a Magnox alloy be left in a cooling pond?

Magnox alloy is reactive with water, which means it cannot be left in a cooling pond after extraction from the reactor for extended periods. In contrast to the Windscale layout, the Magnox design used vertical fuel channels.

Where was the Sizewell Magnox nuclear power station built?

Sizewell A Magnox nuclear power station In all, 11 power stations totalling 26 units were built in the United Kingdom where the design originated. In addition, one was exported to Tōkai in Japan [21] and another to Latina in Italy. [18]
