HEAT SHIELD FOR CABLES

摘要

A heat shield for use with cables in a nuclear environment can include a thermal insulator. The thermal insulator can have a low thermal conductivity and can be formed of a silica glass fiber material, an aerogel, or an aerogel-derived material. The heat shield can mitigate a 650 °C temperature spike caused by a severe accident condition. Cables including such heat shields can operate through a nuclear accident that causes an initial 650 °C temperature spike.
