KOREA HYDRO _NUCLEAR POWER http://www.khnp.co.kr
INDEX • * Location • *Plant flow • -primary side • -secondary side • *The role of mechanical engineering major in KHNP
location KHNP also operates nuclear power plants in Kori, Yonggwang, Ulchin and Wolsong, and several hydroelectric power generation facilities in the Hangang system, providing approximately 40% of the national power supply.
-Plant flow • -The following is a flow diagram for the principles of nuclear electric power generation viewed in a plane.
-Primary Side (1차축) -Rearctot(원자로) Transfers heat to coolant passing through the reactorby absorbing fission energy generated from nuclear fuel. -Steam generater(증기발생기) Reactor coolant pumps transport coolant that has passed through a reactor ; the coolant transfers Heat to secondary feed_water outside the steam Generator tube bundles while it flows inside The tube bundles.
-Primary Side (1차축) -Reactor coolant pump(냉각재펌프) Transfers heat to feed_water system of the secondary side by transporting reactor coolant, heated by the heat generated from the reactor, to steam generators. -Pressurizer(가압기) During normal operation Pressurizer volume is shared; 50% water and 50% steam. The balance between steam and water is controlled By spray nozzles and electric heaters.
-Generator A generator is connected with turbines in one axis; they revolve together as the turbines rotate. It makes electricity by generating a three_phase induction current in a rotator and a stator -Secondary Side (2차축) -Low_pressuretubine Steam passing through the high_pressure turbine again rotates three low_pressure turbines and is con verted into mechanical energy, required for the operation of a generater. -High pressure turbine Heat energy generated in a reactor is transported to turbines in the form of high temperture and high_pressure steam and converted into kinetic energy to rotated the turbines.
The role of mechanical engineering majors in KHNP • The power station consists of millions of parts, and most have dual hardware and key features. Therefore, in need of a lot of mechanical engineers. Engineers design, facilities management, maintenance, and are currently working in the field of non-destructive.. • In particular, the nuclear power plant so that safety is the best and excellent machine requires that you accept the following major engineers and technical training
