Jean-Pierre Mouroux
Jean-Pierre Mouroux is the
Olkiluoto 3 Project Director for
AREVA. With a background in chemical
engineering, Jean-
Pierre was involved
with several
international large
nuclear projects
– from design
and licensing
to construction,
start up and
commissioning
with project control
applications.
Before joining the
Olkiluoto 3 project
in Finland, Jean-
Pierre had already
spent 10 years as an
expatriate, gaining
strong experience
in business development in nuclear
and energy fields, and managed an
engineering company.

project developments in Finland.
While the duration of a construction
project is limited, the involvement of the
plant vendor is permanent in the region
as the latter continues to work along with
its customers to train suppliers and future
plant operators, or offer localized and
expert maintenance.
A product and project
like never before
The OL3 nuclear power plant is an
EPR: the competitive third generation
design by AREVA. It is one of the four
EPRreactors currentlyunder construction
in the world. Other projects include
Flamanville 3 in France, and Taishan 1
and 2 in southeast China.
The EPR is designed to resist plane
crashes and seismic vibrations, and has
quadruple safety device redundancy.
Thanks to a special compartment isolating
the molten core, the core meltdown risk
is further reduced and its consequences
minimized. The safety features on the
EPR reactor are a combination of active
and passive safety systems designed as an
extensionof theKonvoi (Siemens) andN4
French design reactors to increase safety
and to provide better process control over
plant operation. Its main safety principles
are the diversity to prevent common cause
failures, the redundancy to overcome a
single failure and the complementaritybe-
tween active and passive systems, so as to
achieve essential safety imperatives—the
resistance to extreme hazards, the robust-
ness of cooling capability and prevention
of environmental damage. The EPR reac-
tor has a high structural resistance against
earthquakes, its build-
ings are watertight
and flood-resistant.
The reactor building,
fuel building and two
safeguard buildings
are protected by an
airplane crash (APC)
shell which means
the EPR can resist
the impact of a large
commercial airplane.
The electrical
production capacity
of the OL3 EPR is
more than1630MWe.
The power output
of the EPR reactor
originates from the
size of its larger core,
which is capable of holdingmore fuel and
its advanced nuclear steam supply system
comprising four primary coolant loops.
The electrical production is
maximized through reliable components,
proven technologies and in-service
maintenance duringoperation, permitting
shorter unit outages.
Fuel consumption is reduced and so is
productionof long-lifewaste products (by
-15 percent), through improved thermal
efficiency and uranium utilization. Steam
generators, for example, with an axial
economizer provide increased steam
pressure and noticeably increase the
reactor’s thermal efficiency. A neutron
reflector surrounding the core reduces fuel
consumptionby limitingneutron leakage.
It also increases the lifespan of the reactor
pressure vessel by limiting its irradiation
and its embrittlement.
Core catcher: a passive system designed to contain and cool the molten core in case of a core meltdown.
