Costs of continued operation are 1/5 of construction costs

Costs of coal is increased approx. 1.2 billion USD a year as of 2015

1.2 Billion USD Alternative

There is a reduction of carbon dioxide as about 11,000 ton a day in case of Wolsong unit 1.

36 Million USD

Additional costs of carbon dioxide is increased approx. 36 million USD
