Subcooling margin system for cooling fluid in a nuclear reactor

摘要

A monitoring system 10 for providing a display 38 of the margin between actual and saturation pressure as well as a display 68 between actual and saturation temperature for the cooling fluid of a nuclear reactor. The system 10 also has an alarm 46 which is set off whenever the pressure margin to saturation pressure reaches a predetermined limit as well as a temperature margin alarm 78 which sets off an alarm whenever the temperature margin to saturation temperature reaches a predetermined limit.
