Reactor pressure vessels wall lining to be tested

A new wall lining for pressure vessels in reactors will undergo testing in Oxfordshire, it has been announced.

The Joint European Torus (JET) fusion reactor will experiment on the material in order to ascertain whether it will respond in the way that is expected and has extra diagnostics systems to monitor it.

Beryllium and tungsten tiles have been developed for the International Thermonuclear Experimental Reactor (ITER), which is under construction in the south of France.

The next-generation fusion facility will be fitted with the wall lining following experiments at the newly-upgraded JET.

"We had a very good start with high purity plasmas readily established in ITER relevant conditions - a promising sign for the use of these wall materials in ITER," Francesco Romanelli, European Fusion Development Agreement Leader, explained.

Pressure vessels were breached at the Fukushima nuclear power station in Japan following a meltdown caused by the March 11th earthquake and tsunami that struck the country.
