Performance of Insulating Materials for Future Fusion Blankets

摘要

Thermal conductivities of five candidate insulating materials were determined in the temperature range of 300 to 1000 exp 0 C in air, argon, and helium at 1 atm so that a comparison would be made with existing data. These were done in a non-nuclear environment. The test apparatus was a cylindrical shell cooled with water flowing through tubes attached to the shell. The insulation to be tested lined the inner part of the shell which was heated along the axis of the cylinder with a single electric rod heater. (ERA citation 05:009511)
