Decommissioning: AREVA completes first major component decontamination in
PARIS -- August 29, 2013
AREVA (Paris:AREVA) has successfully decontaminated the major components of
the Chooz A nuclear power plant located in Northern France. The first project
of its kind performed by AREVA in France, the decontamination of the primary
loop elements - four steam generators, the pressurizer and the primary loop
lines - is a major step forward in the ongoing decommissioning of the plant.
The decontamination was carried out successfully thanks to the combination of
two AREVA techniques, the CORD UV® and the AMDA®. This operation is based on
the progressive introduction of chemical substances into the primary circuit
which circulate in there over several days, until the end of the process.
Through this process, AREVA significantly reduced the degree of the
components’ radioactivity so that they could be classified as “very low level
waste.” Following their decontamination, these components were transported to
a National Radioactive Waste Management Agency (Andra) facility, in order to
be stored there.
Compared to alternative solutions, AREVA’s decontamination technology produces
a very low volume of radioactive waste, which is also managed by Andra. Once
the process is completed, the used chemicals are decomposed to carbon dioxide
and water, leaving behind no additional waste.
“The successful completion of this operation testifies to the effectiveness of
our process. For over 35 years, this proven, efficient, and economical
solution has enabled AREVA to decontaminate the components of more than 30
nuclear power plants worldwide, including in Germany, Japan, China, and the
United States,” declared Philippe Samama, Executive Vice President for the
Installed Base Business Unit.
