Abstract
The main objective of this research is to develop a new feedwater control logic for Ulchin Nuclear Power Plant Unit 3{approx_equal}4 (UCN 3{approx_equal}4) by incorporating the steam generator level control concept utilized in the UCN 1{approx_equal}2 which have demonstrated their capability of automatic level control at low power levels. The new control concepts adopted from UCN 1{approx_equal}2 are the steam generator level compensation by the feedwater temperature, the variable level setpoint program according to the turbine power, and the two element control scheme at low power levels. The results demonstrated that a stable steam generator level control is possible with the new feedwater control logic at power levels lower than 15%. Therefore, it is highly possible to improve the performance and safety of the UCN 3{approx_equal}4 provided that a further research develops a complete feedwater control system logic applicable to the entire power range and investigates the impact of adopting the new control logic on the system design.
