Abstract
A window for protecting against the radiation from cells or chambers in nuclear plants includes at least one optical unit which provides protection against high-energy and/or neutron radiation, and a frame, the space between the optical unit and the frame being filled with a castable and hardenable material.
Claims16
A window comprising:
- at least one optical unit formed of a material which provides protection against at least one of high-energy and neutron radiation;
- a frame positioned around the optical unit to form a space therebetween;
- and
- a castable and hardenable material filling the space between the optical unit and the frame wherein the castable and hardenable material includes at least one of heavy particles and anti-neutron particles.
