European Space Agency seeking radioactive power for space missions

Belgium-based international engineering and consultancy group Tractebel has been selected to head a research and innovation consortium, designated Pulsar, to conduct research into dynamic radioactive power systems (RPS), on behalf of the European Space Agency (ESA). The RPS being researched would be powered by plutonium-238 (Pu-238). Tractebel was previously awarded a contract by ESA to investigate the practicality of producing Pu-238 in Europe. Pu-238 is not suitable for use in nuclear weapons and most Pu-238 produced over the years (all in Russia or the US) has been used to power spacecraft. The new ESA contract complements, and takes forward, that work.
