a composite procurement specification (RDT Standard P4-3T) prepared from the input of heater manufacturers, users, and the Department of Energy (DOE). This was followed by a test program designed to evaluate the effectiveness of the procurement specification requirements. Heaters were originally procured from three manufacturers - Chromalox, Rama, and Hesco. The heaters were tested in various configurations, sizes, grades, compaction density, and voltage ratings. Various means of limiting heater failure damage by the use of protective devices in the heater electrical circuits, heater standoff designs, and resistance grounding were also accomplished as part of the technology involved in the safe use of electrical resistance heaters. In addition, a limited program evaluating MI cable for trace heating of small piping systems used for heat transport in LMFBR liquid metal applications was conducted. Show Less
