C-M nuclear applications:
Accelerators, spallation and nuclear plants
Fast neutrons are most effectively stopped by a high hydrogen content such as water, paraffin or polyethanes which contain high levels of hydrogen nuclei. Through repeated collisions with hydrogen nuclei, fast neutrons can be reduced to so-called slow neutrons. AB Carlsson & Möller markets Borotron®, a material consisting of stable polyethylene modified with boron. The material can to a great extent eliminate the neutrons through nuclear reaction between the substance boron and neutrons. Borotron® is available in the grades PE-HMW (High Molecular Weight Polyethylene) and PE-UHMW (Ultra High Molecular Weight Polyethylene), which can handle working temperatures up to +80°C to +120°C. For higher temperatures, Carlsson & Möller offers a polyethylene with 20% boron and 10% lithium. This material withstands continuous temperature exposure up to +200°C and short-term temperature exposure up to +300°C. |
