General ASN regulations
• Decree No 2007-1557 of 2 November 2007
– Any nuclear facility (INB) shall assess the impacts on the
“interests” mentioned in the article L593-1 of the Environment
code: health, security, public “salubrity”, nature and
environment protection.
– By this decree, ITER becomes an INB the day the preliminary
safety report is sent to the regulator, meaning in January 2008.
– Be impacts on the health and environment are subject to
this decree.

General ASN regulations
• INB Order - Order dated 7 February 2012 relating to the
general technical regulations applicable to INB
– From the INB order article 1, it is clear that any activity related
to design, construction, operation, decommissioning,
surveillance and maintenance of activities related to protection
of the interests mentioned in the environmental code enters in
the scope of this INB order.
– Beryllium is concerned by these interests, since it can
affect the environment and health.
– From the title III in this order, the defence in depth principle
shall be implemented.
– The INB order establishes a list of internal and external
hazards to be considered in articles 3.5 and 3.6.

General ASN regulations
• Decisions ASN 2013-DC-0360 of the French Nuclear
Safety Authority dated 16 July 2013
– The decision focuses on the control of pollution and the impact on
health and the environment of basic nuclear facilities
– The beryllium is an hazardous substance due to its impact on
health and environment, so the decision is applicable
– The title II related to water sampling, effluent discharges and transfer
in the air/water provides technical data. The process of Beryllium
during assembly and storage could lead to production of liquid and
gas effluents contaminated by beryllium mainly due to plates cleaning
process. These INB articles 3.5 and 3.6 provide requirements in
terms of collection, treatment, transfer and discharge of effluents
mainly articles from 2.3.5 until to 2.3.13 of ASN 2013-DC-0360.

General ASN regulations
• Decisions ASN 2013-DC-0360 of the French Nuclear
Safety Authority dated 16 July 2013
– In particular, the article 2.3.13 requires having a stack design in order
to have a good atmospheric diffusion of releases airborne effluents in
order to avoid their re-use in neighbouring installations. The stack
height cannot be lower than the one resulting from the calculation in
appendix 1 of the decision.
– Additional monitoring of effluents under aerosol form as well as under
a potential liquid form is to be performed as per title III.
– It is specified in article 4.1.1 that the facilities shall be designed,
constructed, operated, decommissioned, dismantled, maintained and
monitored in such a way as to prevent or limit the direct or indirect
discharge of substances likely to cause pollution in the receiving
environment or sewage systems.

authorising ITER Organization to build the licensed nuclear facility
called ITER in Saint-Paul-lez-Durance
– Article III-1:
The confinement of hazardous materials shall consist of two systems, based on
two confinement methods: static and dynamic:
1. A first system, located as close as possible to the materials, provided in
particular by the tokamak vacuum vessel and its extensions, the tritium
processes, the maintenance hot cells and the associated ventilation systems as
necessary.
2. A second system designed to limit releases into the environment, provided by
the walls of the rooms and buildings and the associated ventilation systems as
necessary.
In the parts of the facility where a risk of spread of dangerous materials
exists, ventilation system provisions ensure a negative pressure
cascade compared to atmospheric pressure.

phase, the operator must provide the relevant staff members with training on the
risks associated with beryllium.

• Worker protection provisions will be the following for
beryllium-relevant zones:
– when the zone has been identified as a beryllium-controlled
zone:
• access is limited only to beryllium qualified personnel,
• specific medical monitoring will be associated with this berylliumqualified personnel,
– beryllium monitors will be implemented in the rooms with the
main risks,
– when the zone has been identified as a breathing protection
zone (above 0.2 μg/m3), then the same provisions are
considered as for beryllium-controlled zones, adding the
following requirements:
• air breathing masks will be required for personnel entering these
zones,
• the zones will have higher air renewal rates.

• Only atmospheric releases of beryllium are expected in
ITER (for liquid see slide 26).
• The potential release (stack height 58m) of airborne
beryllium is estimated at:
– during the construction and assembly phase: 6 g
– during the operation phases: 1.5 g
• The actual release should not exceed the values
estimated in the RPrS.

• Beryllium waste management
– The waste management requires that before any production of waste
to identify how to process these waste, in particular Beryllium waste,
and to limit as far as possible and using best techniques at
economically acceptable the waste volumes stored before evacuating
them. [ITER decree].
– Only atmospheric releases of beryllium are expected in ITER. Plasma
operations do not generate beryllium in liquid form. However, it is
perhaps possible that liquid beryllium will be created in the beryllium
laboratory in order to carry out beryllium measurements. Specific
procedures will be put in place in order that liquid beryllium samples
are not released in the industrial effluents (due to agreement with
CEA) and that they are captured and transferred for a specific waste
treatment. The same process of capture will be used for the first
rinsing water. Subsequent rinsing water may be released after
monitoring as an industrial effluent. [RPrS]
