All sodium piping and equipment is heat traced to maintain the sodium in a liquid state. The Pipe and Equipment Electrical Heating Control System controls the rate of heat application to sodium piping and equipment during heatup of empty systems prior to filling with sodium and to maintain heat in operating sodium systems. The Pipe and Equipment Electric Heating Control System is designed to aid in detecting malfunctions and failures within the system. The Control portion except for the control thermocouple is electrically independent of the alarm portion, thus providing a more reliable check on the overall system. Instrumentation is modular to provide for easy removal and replacement. Detailed maintenance procedures will be developed as a part of the detail design work and will be included in the Operation and Maintenance Manual. Procurement specifications will call for detailed maintenance and calibration procedures for each type of instrument
