
Brennilis reactor is an
experimental reactor
moderated with heavy water
and cooled with carbon dioxide
(HWGCR). The reactor was to
have a power of 70 MW.

The startup occurred in 1967.

In 1985 the reactor was
decommissioned.

DECOMMISSIONING
Brennilis marks the first dismantling of a complete nuclear power station in France.
EDF and CEA announced intention to make a transparent process so that it can be
used as a model for dismantling of other plants later.
The process is divided into 3 phases:
Phase 1
This phase was launched in 1985, similar to a refueling outage the fuel is moved to
the spent fuel pool, but new fuel is not loaded, and the fuel on site is evacuated.
Phase 2
Phase 2 started in 1997, consisting of:
•
decontamination and disassembling of the buildings except for the reactor
itself.
•
evacuation of the nuclear waste.
In 2005 phase 2 officially finished.
Phase 3
Phase 3 which is currently underway, consist of:
•
dismantling of the heat exchangers.
•
dismantling of the Reactor pressure vessel (RPV) – ONET TECHNOLOGIES
leader of consortium ONET TECHNOLOGIES/NUKEM TECHNOLOGIES.
•
demolition of the containment (Reactor building).

SCOPE OF WORK
PARTNERS MAINT COMPANY LTD
The equipment is designed for operation in a chamber for
treatment of radioactive waste (CDI) and will be installed in place
in the Brennilis nuclear power plant in France. The equipment will
perform specific operations and is designed to comply with the
requirements of individual technical specifications prepared by
consortium
GМЕ
TECHNOLOGIES).

MAIN DESIGN PROBLEMS
Lack of sufficient input data for the civil construction –
considering the specific conditions due to the place of
operation and considering the specific technological
processes due to the functions of the whole system for
treatment of radioactive waste it is necessary to modify
and change the use of some areas of the reactor
building.
Difficulties with limited space – the tight equipment
overall dimensions are predetermined by the limited
space assumed for operation execution and
incorporation of the systems in the design.

EQUIPMENT CONTROL
The main control mode of the whole equipment during the
process of nuclear reactor dismantling is intended to be from
control room via Ethernet communication.
The reliable and synchronized operation of the devices is
realized by utilization of contemporary technologies and
concepts.
The equipment is also able to operate in maintenance mode
and emergency mode during which the control is accomplished
by local control panels.
