Containment materials

A general approach to containment materials will be developed during this teaching unit, covering the properties required for use, the different classes of containment matrices and the associated synthesis methods. Structure-property relationships in relation to the containment of radionuclides and/or toxic chemical elements will also be described. Materials covered will include glass, glass-ceramics and ceramics.

Hourly volumes* :

            CM: 12h

            TD : 8h

The objective of this teaching unit is to understand the approaches used to define, develop and characterize materials (glass, vitroceramic, ceramic, hydraulic binders) intended for the confinement of radionuclides and/or toxic chemical elements.

Basics of radioactivity

Solution chemistry applied to actinides

Advanced inorganic materials

Final inspection

• Desired usage properties and associated constraints:
• - Containment of radionuclides and chemical toxins (glass, glass-ceramics, ceramics, hydraulic binders)
• - Separation/sorting of radioelements by crystallization/precipitation operations
• Classes of materials and synthesis routes in nuclear environment:
• - Glass (borosilicate, phosphate, aluminosilicate, etc.)
• - Ceramic materials
• - Hydraulic binders
• Relationships between solid structures and expected properties (case studies):
• - Formulations of glasses and ceramics in relation to waste streams (radioactive, toxic, etc.)
• - Formulations of hydraulic binders for saline waste streams (sulfates, nitrates, etc.)
