Interim storage unit for radioactive waste

Today in Gorleben there are two interim storage units for radioactive waste. The Gorleben transport container storage unit (Transportbehälterlager Gorleben) is used for short-term storage of spent fuel elements and for vitrified, highly radioactive waste from German nuclear reprocessing plants. The fuel elements and vitrified waste block containers are in dry casks standing in a hall above ground and cooled by the surrounding air. Permission has been granted to store 420 dry casks on the site.

In the Gorleben waste dump (Abfalllager Gorleben), waste which emits negligible amounts of heat is also stored in the short term; this comes mainly from German nuclear power plants, but also from research and industry.

On the site, the German Society for the Construction and Management of Long-Term Waste Storage Units (DBE mbH) runs what is known as a "pilot plant", which may become a long-term storage site for highly radioactive nuclear waste.

At present, however, this use is extremely controversial and it has not been finally decided upon yet. The choice of Gorleben as a site was made in 1977 by the Minister-President

 (rock salt) as a host rock for a final repository was a step which eliminated from the start any alternative locations such as the clay or granite formations favourised in other countries for this purpose. Specific exploratory geological drillings were carried out between 1979 and 1999, and from the early eighties the results showed that the Gorleben salt dome could actually be unsuitable because of its unstable roof rock and as it has contact with the groundwater

Another discovery made by the exploratory drilling was that saliferous groundwater moves both from the sides and the top of the salt dome towards the surface, meaning that if it came into contact with highly radioactive material, the result would be a contamination of the biosphere

 criteria, Gorleben was judged the least suitable out of several salt domes. Some critics complained that the exploration was in fact a hidden attempt to build the storage unit. Despite the findings, further exploration has not been cancelled but only put on hold since 2000-10-01. This break, described as a "moratorium", is to provide time to sort out questions on the concept behind the final repository and its security.

Those in favour of Gorleben as a location for the dump have called for the moratorium to be lifted, to let further exploration go ahead; its opponents have demanded a comparison with several alternative halite locations, as is usually mandatory for large-scale plans. Furthermore, they consider the geological results so far to be convincing enough evidence that Gorleben is an unsuitable spot for a nuclear waste repository.

's center-right Federal Government lifted the moratorium and re-started the exploration process. Large-scale protests promptly resumed.

Pilot conditioning plant

Near the exploratory mine and the interim storage hall, there is still a "pilot conditioning plant". Here, tests are to be made of conditioning the fuel elements in order to store them in a deep repository, and also to reload the containers for the vitrified waste blocks into containers suited to long-term storage. The dry cask storage containers themselves are not suitable for long-term storage and can not be placed in the salt dome for technical reasons. However, at present the plant may only be used for repairing damaged containers, according to an agreement signed by the German government.

Today, protests still take place against nuclear energy and the plans for waste disposal at Gorleben: they reach a climax in the yearly transport of dry cask containers by rail and special lorries through northern France and Germany to the interim storage unit. For the last few years, this transport has usually been carried out in November; it is accompanied by a huge police presence.

In November 2008, a shipment of radioactive waste from German nuclear plants arrived at a storage site near Gorleben after being delayed by large protests from nuclear activists. More than 15,000 people took part in the protests which involved blocking the route with tractors and blocking trucks with sit-down demonstrations.
