Abstract

Abstract

The fault of main feed water regulating valve of CP600 nuclear power units occurs frequently. This paper analyzes several fault conditions frequently occurred on main feed water regulating valves, and studies the stuck of the main feed water regulating valve of CP600 simulator. Three control schemes are compared and the optimal control scheme for the hot standby condition is proposed.
- Main feed water regulating valve,
- Severe condition,
- Valve stuck,
- Coupling effect
