Nuclear Power in South Korea - Reactor Overview

Reactor Overview

South Korea has a relatively smaller generating stations, only four, but each station houses four or more units, and three sites have more reactors planned. Thus Korea's nuclear power production is slightly more centralized than most nuclear power nations. Housing multiple units at each site allows more efficient maintenance and lower costs, but reduces grid efficiencies. Some of the Wolsong reactors are Pressurized Heavy Water (PHWR) reactors with designs based on Canadian CANDU technology.

In 2013, in response to a petition from local fishermen, Korea Hydro and Nuclear Power (KHNP) renamed its Yonggwang as the Hanbit plant, and its Ulchin plant in North Gyeongsang province was renamed as the Hanul plant.
