A member of the Dutch Socialist party has requested the country’s government to
‘increase and extend’ research into plutonium transmutation at the European
Commission-owned Petten research reactor in the Netherlands.
Diederik Samsom, a former member of Greenpeace, submitted the request to the
government on 26th June, after the positive results of a recent plutonium
transmutation experiment – designed to reduce stockpiles of plutonium – were made
public. In his request, Mr Samsom asks the government to consider an “increase and
extension of the research, (in order) to contribute to a more effective and
efficient reduction of plutonium stockpiles – of both civil and military origin.”
The Dutch nuclear research and consultancy group, NRG, told NucNet that the item
is now “on the political agenda”, and will be “discussed further”. It adds that
other political parties in the Netherlands support the importance of the
research, but are not prepared to increase financial support to the project “at
this stage”.
A recent plutonium transmutation experiment at Petten – carried out by NRG in
conjunction with the Japanese Atomic Energy Research Institute (JAERI), and the
Paul Scherrer Institute in Switzerland – showed that the irradiation of
plutonium, when embedded in inert matrix fuel, has the potential for “highly
efficient plutonium burning”.
NRG said: “With this recent developed technology, the net plutonium consumption
in light water reactors is four times higher than with the traditional
mixed-oxide (MOX) fuel concept. This is achieved by the use of uranium-free fuel,
which generates no new plutonium during irradiation”. NRG, together with JAERI and PSI, says research will now focus on “higher percentages of transmutation, as well as on transmutation of other elements that contribute to the lifetime and radio-toxicity of nuclear waste”.
Construction of the High-Flux Reactor at Petten started in 1957, and the reactor
celebrated 40 years of operation in November 2001. It will reach the end of its
operational lifetime in 2015, and studies for a replacement reactor are ongoing.
