Between60 and100percent nominal
output, the EPR reactor can adjust its
power output at a rate of 5 percent
nominal power per minute at constant
temperature, preserving the service life of
the components and of the plant.
Building it!
“With a lifetime of several decades
for the plant, it is essential that, on the
construction site, every worker present is
aware that each task realized is important
for the next 60 years,” said Bob SALM,
nuclear safety and licensing manager for
the OL3 site.
Security, nuclear safety and quality
are indeed an essential part of the daily
work on OL3. A dedicated team focused
on nuclear safety culture ensures the
excellent level of understanding, diffusion
and respect of the principles, which
is a challenge in such a multicultural
environment. As an onsite employee
would say: “The nuclear safety culture is
basically our Bible.”
OL3 today
The overall project completion
reached 87 percent at the beginning
of 2014. More than 95 percent of the
documentation is now completed which
signals a strongly mature final design.
Three-quarters of the required licensing
documentation for the construction
and commissioning phases have been
submitted to customer TVO and the
Finnish safety authority STUK.
The physical progress of the OL3
plant includes completion of 95 percent
of the piping installation, 80 percent of
the ventilation, electrical installation
and finishing works, and 25 percent of
mechanical standalone instrumentation
and control (I&C) commissioning.
Earlier in 2014 a number of
important milestones were achieved.
Following intense preparation, the reactor
containment tightness test (CTT), an
operation that consists of pressurizing
the reactor building to test its leak
tightness, was performed on the OL3
site. The test was successfully completed
on February 12, 2014. On April 1, 2014,
the project teams received TVO’s
authorization to launch the I&C system
tests based on the quality of the I&C
documentation prepared by the AREVA-
Siemens consortium. The tests started on
the I&C platform at the AREVA test bay
in Erlangen, Germany.
Together with this positive step
forward, the OL3 I&C system detailed
architecture was validated by the Finnish
safety authoritymid-April 2014.Thiswas
a major step for the project and its team.
Tests on the I&C systems are currently
fully on track.
In the nearby town of Rauma, volunteers from the construction site are joined by families who participate in
Raum’Areva, an annual AREVA-organized running event in the Finnish wild country.
