- Customisable: materials can be adapted to specific radiation protection requirements
DESCRIPTION
Novashield® HE (high-efficiency) is a new range of hydrogenated, neutron-absorbing and fire-resistant materials
This range of materials cover all the needs of the nuclear sector, installations and embedded systems. Their use is recommended during both the design phase and the operating phase and they can be designed for fusion and fission.
Specially designed for nuclear fusion projects
As part of the ITER program and scientific challenge, Lemer Pax has studied, developed and proposed solutions to meet ITER’s design needs.
Novashield® HE materials, a worldwide first, are designed based on a new technology combining optimum radiation protection, high fire resistance capacity and adaptability for specific neutron spectra. It represents a technological breakthrough in design, combining optimum protection against neutron and/or gamma radiation with compliance with fire safety standards.
These hydrogen-rich low density materials are fire-resistant. In accordance with Euroclass NF EN 13501-01, they have a very limited contribution to fire. Compared to commonly used materials, they comply with the fire safety standards. Thus, in the event of a fire, the Novashield® HE range retains its radiation protection properties.
The range of high-performance neutron-absorbing materials allows to reduce exposure to neutron radiation. They can be customised to provide simultaneous protection against gamma rays.
The Novashield® HE range is suitable for the nuclear industry, the cyclotrons, the particle accelerators, etc.
Novashield® HE: materials with customizable shapes and sizes
To date, seven product references, from three families: mortars, flexible materials and rigid materials, are developed, tested and applied.
