Breeder technology has been used in several experimental nuclear reactors.

The decommissioning of a small experimental reactor on the Sellafield site has been continuing for some years.

For research purposes, the following experimental nuclear reactors have already been built in Indonesia:

An international group may build a $5 billion experimental reactor.

In the 1960's the United States launched an experimental reactor into space but it was quickly shut down after a failure.

Last ditch research was conducted in an experimental nuclear reactor at Haigerloch.

"We also have a few experimental reactors in operation which use the atomic fusion process but they're not very efficient up to now."

None of the experimental reactors, however, was used to produce material for weapons, officials here said.

TerraPower is looking for a country that is willing to house an experimental reactor.

If built, the experimental reactor would probably stand some 10 stories high and cost at least $6 billion.
