TN MW®: Modular Triple Purpose Cask for Waste

Efficiently manage your various types of radioactive waste with a triple-purpose versatile solution: transport, interim storage, and final disposal

Implement technically and economically viable solutions to manage your waste.
Keep in mind that not all waste types generated today have a defined disposal solution, and many will likely require interim storage for at least 40 to 50 years.
Minimise handling and reconditioning operations to reduce both operational costs and radiological impacts.
Address the transportability challenges associated with long-term interim storage, as future transport regulations and technical specifications applicable 40-50 years from now have yet to be fully defined.

Ensure versatile waste compatibility: support solid, liquid, and gaseous waste forms
Standardise key elements such as the cask closure system (containment), external dimensions, package mass, construction materials, and shock absorbers to maximize efficiency and regulatory compliance
Adapt internal shielding configurations to meet the required performance for each specific waste type
Customise baskets to accommodate a wide range of waste geometries and characteristics
Provide interim storage capability for durations of up to 100 years
Guarantee transportability after storage with minimal additional operations
Ensure final disposal compatibility by incorporating current best practices, anticipated future trends and regulatory recommendations from safety authorities, and ensure safe behavior during the “reversibility” period of disposal
Simplify maintenance through life-cycle-oriented design
Support both wet and dry loading/unloading processes
Enable flexible transport modes (road, rail and maritime transport) including integration within ISO 20’ containers

Modular design of TN casks for greater flexibility and simplified licensing processes
Enhanced robustness and safety through optimised engineering
Significant reduction in manufacturing lead times and costs
Cost-effective solutions achieved by pooling efforts among various stakeholders and limiting the need for project-specific developments
Optimised waste streams management during operational or decommissioning phases (including conditioning, transport, interim storage, and final disposal) resulting to reduced waste management costs
Applicable to a wide range of waste types, such as:
