The waste disposal facility in the Aube district is the second surface waste disposal facility built in France.It is located in the Aube district, and has been operated by Andra since 1992.With a footprint of 95 hectares, it is licensed for the disposal
of 1 million cubic metres of low- and intermediate-level, short-lived waste packages. The CSA is located a few kilometres
away another Andra facility, currently in operation for very-low-level waste, and collection and storage of non-nuclear power waste
(the Cires).
For nearly 20 years, Andra’s waste disposal facilities have been developing exemplary industrial activity in the Aube district, in accordance with strict rules
and procedures, and full transparancy, with the constant aim of protecting man and the environment.
To find out all about the centres and understant how radioactive waste is managed, you are welcome to visit the Andra's waste disposal facilities in the Aube district, and really see what happens in these active industrial installation.

What is aNdra?
The French National Radioactive Waste Management Agency (Agence nationale pour la gestion des déchets radioactifs-Andra) is a public industrial and commercial establishement. Placed under the supervision of the respective ministers for energy, research and the environment, it is responsible for implementing and guaranteeing safe solutions for protecting current and future generations from the risks of french radioactive waste.

the waste disposal facility in the aube district (csa)the csa is located on land spreading across three municipalities in the aube district: soulaines-dhuys, epothémont and la ville-aux-Bois. it covers 95 hectares, 30 of which are dedicated for disposal.
this surface disposal facility is designed to receive low- and intermediate-level, short-lived radioactive waste (lilW-sl)
Key Figures • 1 million m3 licensed disposal capacity
• 267,496 m3 of waste in the disposal facility by the end of 2012 (26.7% of the total licenced capacity)
• 116 disposal structures closed as at the end of 2012 (about 420 are planned in due course)
Until the end of 1994, LILW-SL was stored in the Manche disposal facility (CSM).
in the 1980’s, the government decided that a second disposal facility was needed to take over from the csM. Preliminary research was then carried out in four districts (Aube, Indre, Haute-Vienne and Maine-et-Loire).
in 1987, the aube site was chosen for extensive geological survey. in 1989, a decree authorised the French Alternative Energies and Atomic Energy Commission (CEA), of which Andra was a part at the time, to create a radioactive waste disposal facility there.
Based on its experience acquired over a quarter of a century of operating the CSM, the csa was commissioned in 1992.
Waste disposed of at CSA is conditioned in concrete
or metal packages. Waste packages are placed in reinforced concrete repository structures 25 metres square and 8 metres high, that
are constructed as needed. Once they are filled,
the structures are closed with a concrete slab and
then sealed with an impermeable coat. At the end
of operation, a cap formed mainly of clay will be
placed over the structures to ensure long-term waste
containment.
once the authorized limit (one million cubic metres) has been reached, the csa waste disposal facility will be monitored for at least 300 years.

a basic nuclear installation (iNB)
The waste disposal facility in the Aube district
(CSA) is classified as a basic nuclear installation
(French acronym INB). It is regulated by the
French Nuclear Safety Authority (ASN) which
carries out a number of inspections on the site
every year.
in accordance with the Nuclear transparency and security act, a local information commission (cli) was set up to monitor the disposal facility’s activities and regulary inform local elected officials and the neighbouring population of its operations.

Why disPosal?Radioactivity is a phenomenon which decays naturally with time. in order to isolate radioactive waste for as long as it represents a hazard for man and the environment, France, like many other countries, has opted, for more than 40 years, to dispose of it in facilities that are adapted for each type of waste.To facilitate management, radioactive waste is classified according to five categories based on level of radioactivity and half-life.The principle of disposal consists in isolating the waste for a sufficiently long period of time to ensure that the radioactivity in contact with humans no longer presents a health hazard due to natural decay.
three disposal solutions are currently planned in France to take over all radioactive waste:
surface repositories
near-surface repositories (under design)
deep repositories (under design)

low- and intermediate-level, short-lived radioactive waste (lilW-sl)
LILW-SL is mainly (for up to three-quarters) made up of small equipment (gloves, clothing, tools, etc.)
contaminated during maintenance and operation
of French nuclear power plants. Such waste also
comes from hospital, university and research centres,
cleanup operations of sites polluted by radioactivity
and the dismantling of nuclear facilities.
This waste mainly contains short-lived radionuclides
(half-life less than or equal to 31 years). It may also
contain long-lived radionuclides in very limited
quantities. Due to radioactive decay, the impact of
short-lived radioactive waste is negligible after 300 years.
According to Andra’s National Inventory of Radioactive Materials and Waste 2012, as at the end of 2010, lilW-sl accounted for 63% of the total volume of radioactive waste produced in France, or 830,000 m3 and 0.02% of the total radioactivity of radioactive waste in France.
At the end of 2012, 267,496 m3 of radioactive waste had already been placed in the CSA and 527,225 m3 in the Manche disposal facility (CSM).
WHERE DOES LILW-SL COME FROM?

Five categories of radioactive waste
Radioactive waste can be classified according to a number of criteria: origin, physical and chemical nature, level and type of radioactivity, lifetime, etc.In France, radioactive waste is managed according to classification based on the following:
- its radioactivity expressed in becquerels (Bq) per gram. The radioactivity (or simply "activity") of waste can be very-low, low, intermediate or high level.
- its lifetime, which depends on the half-life of each radionuclides it contains. Waste whose radioactivity mainly comes from short-lived radionuclides (half-life ≤ 31 years) is referred to as short-lived waste, while waste with a significant quantity of long-lived radionuclides (half-life > 31 years) is referred to as long-lived waste.
there are five categories of radioactive waste:
• very low-level waste (VLLW)
• short-lived low- and intermediate-level waste (LILW-SL)
• long-lived low-level waste (LLW-LL)
• long-lived intermediate-level waste (ILW-LL)
• high-level waste (HLW)
Some waste, mainly hospital waste, have a half-life of less than 100 days.Because of its very short half-life, such waste is stored on site until its radioactivity has decayed away naturally, which takes from a few days to a few months, long enough for the radioactivity to naturally decay.

What is radioactive Waste?The term radioactive waste refers to substances for which there is no planned or intended use.
In France, radioactive waste is produced by various economic activities involving the use of radioactive materials. It is managed through the implementation of specific processes.
distribution of French radioactive waste produced according to economic sector:
Nuclear power industry 59%
Research 26%
Defence industry 11%
Conventional industry (excluding nuclear power) 3%
Medical field 1%

did you know Radioactivity is a phenomenon that has occured naturally in the environment since the Earth was first created. It is present in water, air, rock and even the human body. It decays naturally with time, at a rate depending on the radionuclides present.
The half-life is the time taken for half of the initial quantity
of a given radionuclide to decay.

➡the lilW-sl circuitthe waste circuit from production to disposal comprises several steps, each requiring strict and rigorous inspection.
08
Package preparation
Before it reaches in the disposal facility, most of the waste is treated (compacted, solidified, etc.) and packaged (in a metal or concrete container) by the producers.
After packaging, a package of LILW-SL consists of 15 to 20% of radioactive waste and 80 to 85% of encapsulating material (grout).
Production
LILW-SL mainly comes from the nuclear power generating industry, but also from hospitals, university and research centres and from clean-up and decommissioning operations.
delivery of packages to the csaThe packages are transported from the producers' permise to the Andra disposal facility by road or rail, in compliance with strict international regulations (transport is the responsability of the producers).Annual average: six trucks per workday.

arrival at the disposal facility
An administration check on the delivery and a radiological check on the packages are carried out when they arrive at the disposal facility.
Each package is marked with a barcode, a sort of ID card giving the nature, content and origin of the package.
Processing of certain packages before disposal
• Certain metal drums (containing plastic, gloves, etc.) are compacted in order to reduce the volume.
and
• Grout is injected into large metal containers for the more bulky.
disposal Every year, about 12,000 m3 of packages are placed of in the concrete structures of the CSA.

Protecting present and future generationsto ensure that the disposal facility has low an impact as possible on man and the environment, andra carries out regular and thorough monitoring.
According to the regulations, the annual dose of
radioactivity from industrial activities must be as low
as possible and may not exceed 1 milliSievert (mSv)
for the population.
To ensure that the impact of its activities is as small
as possible in and around the disposal facility, the CSA takes more than 14,000 measurements every year. These include:
• radiological checks on air, water, sediment
in the nearby streams, plants and the food chain;
• physical-chemical checks on water;
• ecological checks on fauna, flora and aquatic
habitats.
Every year, Andra publishes a report presenting the
results achieved in terms of nuclear safety, radiation
protection and environmental monitoring.
These results are available on Andra's web site and
upon request.
Furthermore, since 2009, andra has been an active member of the 'National network for the measurement of environmental radioactivity' and concerning this disposal facility, it sends in about
350 measurement results every month, which are
then published on the www.mesure-radioactivite.fr national website.
At the end of its operating life, surveillance of the
disposal facility will continue, for at least 300 years, until it has reached a level of safety requiring no
further human intervention.
* Evaluation based on a hypothetical most exposed group.
The radiological impact of the CSA for the year 2012 is evaluated at 0.0013 microSieverts (µSv)*, or less than 100,000 times less than the regulatory limit and hence the same fraction of the average impact of natural radioactivity in France.
ENVIRONMENTAL MONITORING
MONITORING OVER SEVERAL CENTURIES
did you know 1 msv per year (millisievert) is the maximum allowable annual dose for the population.
this is equivalent to
• 3 lung X-rays
• 9 months spent in a granitic region
• 1 year at an altitude of 1,500 metres
• 17 months in the Paris region
• 7 roundtrip flights between Paris and San Francisco.

conserving and handling down the history of the disposal facility
To enable future generations to understand the choices
we have made, change them if they want to, and take
any corrective measures they consider necessary, it
is important for them to have access to the essential
information concerning the disposal facility (origin,
content, etc.). andra has taken steps to conserve the history of the disposal facility and ensure that it is readily available for several centuries.This includes preparation of a precis (with a brief
description for the general public, illustrations, etc.)
and a detailed record (with complete reports, technical
plans, inventories, etc.). The detailed record is printed
on permanent paper (lifetime from 600 to 1,000 years)
and kept in the French National Archives, as well as in a
dedicated room inside the disposal facility.
