Loss of Normal Electrical Power for the molten salt pump

release time：2016/10/29 clicks：

Loss of electrical power will cause the salt pump motor, cooling air blower motors, and preheaters on the salt piping and equipment to cease operation. Salt in the salt circulating system will become stagnant and will cool from the normal operating temperature of 1300°F. salt from freezing (930°F mp) in the piping and the pump, it must be drained into the salt storage tank. Since solid salt in the freeze valve can be thawed most quickly with electric heaters, a reliable, emergency source of electric power is required. It is operated once each week to maintain readiness and it has never failed to start.

During power failure the emergency power supply will also be used to operate the salt pump lubrication and the shield plug cooling systems to protect pump shaft bearings and seals from overheating.
