In Asia, South Korea built four CANDU reactors at te Wolsong site. Units 1-4 were commissioned between 1983 and9, with Unit 4 being thee lass CANDU 6 built outside Canada.

First-of-a-kind nuclear construction in a new country involves signitant financial risk. Capital costs for a twin- unit EC6 plant are estimated in thee range of $4.000- $6,000 per installad kilowat, depensing g on site conditions, regulatory requirements, andthee defaule of local content. For a 700 MWe unit, this translates to a total project cost $3- a facional commant for any developineg ecy.

Several mechanisms exist to liquidite this burden.
