AREVA to supply hydrogen recombiners to Japanese reactors

22 October 2012

AREVA has announced that it will equip the Japanese reactor fleet with one hundred of its Passive Autocatalytic Recombiners (PARs). PARs are state-of-the-art passive safety devices used to prevent the build-up of hydrogen into reactor containment vessels so to preserve the integrity of the reactor.

PARs do not require any operator intervention or power. They, therefore, continue to work even in the case of a station blackout. The devices are easily installed, and generate almost no operational or maintenance costs, as they use the catalytic oxidation to convert the hydrogen into harmless steam.

“PARs represent a major step forward in nuclear plant safety, and AREVA is proud to be driving this progress with its Safety Alliance Program”, said Philippe Samama, AREVA’s executive vice president for the Installed Base Business Unit.

To date, a total of 140 plants worldwide have been or will be equipped with AREVA’s PARs. Further orders have already been received this year and tenders to supply PARs to various nuclear power plants in Europe and Asia are currently underway, AREVA said in a 19 October statement.
