Introduction

1. History of the management of radioactive waste Between 50's and 1983

Introduction


Radioactive waste : 100 000 tons
Storage : bottom of the oceans in concrete boxes
Origin : UK, Switzerland, USA...
Initial idea: decrease activity for 500 years

Now In France : Volume of waste produced per year and inhabitant in France

Sources : www.andra.fr

Around 100 000 m3 of radioactive waste stored

It is managed by Andra

2. Radioactive wastes from electronuclear industry : National Inventory 2004

Medium activity long lifespan wastes (MA VL)

Introduction

Hight activity wastes (HA) 0,2% 91,68% r*

Stored inside glass in an inox boxe.

Non recyclable

4,4% 8,22% r*

Stored in an inox boxe.

1. Presentation of Andra

I – General frame

The French National Agency for Radioactive Waste Management



A public industrial and commercial organisation



Created by the Act of 30th of December 1991



Managed by 3 ministers : Environment, Industry, Research

3 missions

Industrial

Research + a public service mission

managed by laws

Information

2. « Loi de programme du 28 juin 2006 » Sustainable management of radioactive material and waste

I – General frame





Objectives and deadlines of the Andra



Studies about HA and MAVL wastes

3 Main lines Separation and transmutation of long lifespan nuclear waste

CEA

Sustainable storage outside

Reversible storage in deep geological layer

Andra Mission : the HAVL project

3. The HAVL project

I – General frame

Aims :

An industrial plant of storage near Bure (55) An observatory of the environment

Planning :  2005 : Publication of a file about the feasibility of a reversible storage of HA and MA VL waste  2015 : Application for the authorization of the creation of a geological storage centre  2025 : Beginning of the running of the centre (under authorization and after a public survey)

Now :

A laboratory running since 1999 in the site Several data recorded

Find the best conditions for the future storage site Have initial datas for the watching of : fauna, flora, soil…

4. The work for the HAVL project Record data of the soil into a map for the observatory  Existing soil map : 1/3 of the observation area (2002)  The remain : mission of the L.S.E. (ENSAIA) for june 2008 Ligny-en-barrois

Observation area (~900km2)

Location of the observatory not yet fixed

Montiers –sursaulx Bure

LABORATORY

Transposition area (~200km2)

Location of the storage not yet fixed

II – Field work

1. Geological frame of the soil of the studied area

II – Field work

• All the area is on sediments of the Secondary and is part of the pond of Paris. • Layers have a pendage from 1 to 1,5 degrees on average, steered toward the centre of the pond. • Five different geologic layers in the sector of study (Valanginien, Portlandien, Kimmeridgien, Oxfordien and veneers of silt)
Geological data and field work

2. In the field 1) definition of the perimeter of the different areas

II – Field work

2) digging holes with an auger 3) recognition of the type of soil through the study of the profile 4) laying out of the different areas on a map according to :




geological map




contours




landscape structure

III - Digitalisation

III - Digitalisation

Capturing, Storing, Analyzing and Managing data associated attributes spatially referenced to the Earth With Mapinfo (Claritas/axsiom) 1) Superimposing of our map scanner on the IGN 2) Drawing of the different perimeters = polygons One colour for one type of soil = layer 3) Checking : gaps between two polygons or superposition 4) Formatting depending on the thematic analysis

III - Digitalisation IGN map

III - Digitalisation

Create a polygone Modify it Zoom

Management of the layers

III - Digitalisation

Formatting : possible uses of a map

III - Digitalisation

For each hole : Data are recording ( pH, humidity rate...) and put in a computer (b.e.excel) Thematic analysis : 1) transfert data from excel to a mapinfo table 2) Selection of the parameter wanted on the map (b.e. type of soil, pH)

III - Digitalisation

IV – Conclusion

700 km² of the observation area is done

V – Pros & Cons An interesting project :  Review and complete the basic notion of soil : how to define and classify a soil according to its texture ...etc Work in the field 

Work on a GIS : important tool for engineers its use is quite simple

 We learn more than how to do a map :
How to manage the problems
The RMQS 

ANDRA's initiative : professional impact of our job

RMQS à Dommartin-St-Père

An other example of use:

RMQS Network of measures of the quality of soils 16 km between each hole measures and observations in the centre of each grid every ten years

Many thanks to Sophie Maillant and all the other persons who helped us in our work.

Any question???
