Summary
A thermal analysis was performed to establish requirements for a heating system for the standpipe bubbler sufficient to maintain the sodium in the standpipe in a liquid condition over the range of operating conditions. There are very few formal requirements on operating limits or hardware selection. Therefore, consideration was given to standard types of equipment employed in a conventional manner. The recommended heating system consists of metal-sheathed resistance heaters with three units being mounted on standoffs and equally spaced around the pipe. The heaters would be covered by a layer of insulation having both interior and exterior coverings of reflective metal sheathing. The pipe temperature would be monitored by thermocouples, and the heaters would be turned on and off on a cycle of approximately 4 hours to maintain the pipe at a temperature of 800/sup 0/F +- 50/sup 0/F.
