Abstract

1457670 Heating by glow discharge VARIAN ASSOCIATES 10 June 1974 [11 June 1973] 25718/74 Heading H5H A nuclear fuel rod thermal simulator comprises a stainless steel tube 16, a part of which 15 is hermetically sealed and is heatable by glow discharge. The part 15, bounded by insulators 17, 17<SP>1</SP>, contains a discharge sustaining gas (e.g. hydrogen or helium) at reduced pressure (e.g. 2À5 torr) and has a central electrode 18, the stainless steel tube 16, earthed, being the other electrode. Part 15 may be heated to 900‹ C. Tube 16 may have a liner 37, of tungsten, molybdenum or an alloy of one of these with a platinum metal. Electrode 18 may be a tungsten wire or a tungsten tube partially filled with silver that is vaporized at operating temperatures and acts as a heat pipe. Insulators 17, 17<SP>1</SP> may be of thorium dioxide and shaped at the facing ends to provide long current leakage paths. Thermocouple 23 has connecting leads 25; current supply to electrode 18 is via lead 22.
