Topics

Operations in the nuclear power industry produce a wide variety of radioactive wastes. The predisposal waste management is to produce waste packages suitable for storage, transportation and final disposal. Cementation is a widely applied technique for the conditioning of low- and intermediate-level radioactive wastes. Compared with other solidification techniques, the cementation process is relatively simple and inexpensive. Moreover, calcium silicate cements show many advantages, such as easy supply, compatibility with aqueous wastes, good self-shielding, and high alkalinity which allows to precipitate and thus confine many radionuclides. However, specific issues have still to be addressed, such as the limitation of adverse cement-waste interactions which may affect the quality of the resulting solidified waste form, or the understanding and prediction of long-term properties of the waste packages and cement barriers. There is also a need for safe processes minimizing the production of secondary wastes. The objective of the symposium is to promote the exchange of advanced information on the ongoing research and development activities dealing with cementation of nuclear wastes, from elaboration of waste packages to their final disposal.

The following topics will be primarily considered.

❶ Methods of production of cement-waste forms

- Performance requirements and implementation methods
- Formulation for various kinds of wastes (metallic wastes, ashes, spent sorbents including ion exchange resins, hydroxide flocks, evaporator
   concentrates and other salt solutions, organic-containing wastes)
- Formulation methodologies
- Processes involved: mixing device designs, packaging options ; engineering feasibility and implementation in real site

 ❷ Physico-chemical processes occurring in cement-waste forms at early age

- Cement-waste interactions
- Factors influencing rheology, setting, hardening, hydration rate, heat production, pH and pore water evolution
- Evolution of mineralogy and microstructure

 ❸ Influence of external and internal factors on long term properties of cement-waste package and cement barriers

- Effect of water, temperature, radiation, waste / cement interactions
- Gas generation and evacuation
- Micro and macro-cracking
- Radionuclides retention and transport
- Interactions with other cement barriers
- Monitoring techniques
- Modelling of long-term behaviour, service life prediction
- Decontamination of concrete structures

❹ Emerging and alternative cementitious systems

- Low pH cements
- Calcium sulfoaluminate cements
- Geopolymers
- Non hydraulic binders such as magnesium cements, calcium phosphate cements…
