The Dounreay site at Caithness was opened in 1955 to develop fast reactors.

After Dounreay's closure, there are hopes that staff can work in the worldwide decommissioning and decontamination (D&D) market.

Dounreay was originally ordered in 1988.

All the reactors at Caithness have now closed.

The nuclear power plant in Krümmel was closed on 4 July 2009 after a short circuit in the transformer, but is set to reopen in 2010 after new transformers are supplied.

A control room located on the site monitors and records every process of the reactor.

The emergency control room contains two of the plant's six emergency diesel generators.

The plant generates electricity through nuclear fission.

The plant is part of Germany's plan to reduce carbon emissions throughout the country.

The plant is primarily made up of two buildings; the reactor building and the turbine building.

Sellafield, UK.

As the European demonstration project for nuclear reactor decommissioning in the UK, Project WAGR aims to show that a full-size reactor can be dismantled safely and cost effectively, with minimum risk to the environment.

Since its shutdown in 1981, a large amount of work has been completed at the site. For each piece of equipment, specific tools and methods must be devised and used.

The delayed 1.2GW Watts Bar 2 PWR is to be completed.

Watts Bar Unit 2 will cost the TVA around $2.49bn to complete.

Watts Bar Unit 2 is located next to Unit 1, just south of Watts Bar Reservoir.

Watts Bar lies on the Tennessee River, near Spring City.

TVA's three nuclear plants (Browns Ferry, Sequoyah and Watts Bar) provide about 30% of TVA's power supply.

Siemens is refurbishing and upgrading the turbine island.

Watts Bar is TVA's third nuclear power plant.


Westinghouse is building four AP1000 nuclear plants in China.

Engineering design and some procurements have already begun for the planned Chinese plants.

Construction of the Chinese reactors is expected to start in 2009.

The four plants will be built in pairs at Sanmen and Haiyang.

Passive systems on the AP1000 use gravity, natural circulation and compressed gas – there are no pumps, fans, diesels, chillers, or other rotating machines in the safety sub-systems.

Westinghouse is expected to bring the first plant on line in 2013.
