In order to maintain the flue temperature and guarantee the gas can combustion fully, gas pressurecontrolloop and the sub flue suction control loop are designed.
In order to carry out power transient tests for PWR fuel element in China Advanced research Reactor (carr), the research and conceptual design of 3he pressurecontrolloop were completed.
It can display instantaneous and cumulative flow division simultaneously, and regulate flow by controlling parameter in order to achieve close-loopcontrol of pressure in high-pressure pipe network.
