Doosan Heavy Industries & Construction is entering the “spent nuclear fuel” container business. Until now, there has been no domestic firm with the design technology.
Doosan Heavy Industries & Construction announced that it has signed an agreement with NAC International of the U.S. in Kyobo Tower in Seocho-gu, Seoul, on Aug. 25. Under the agreement, the two companies will jointly develop a Korean model of CASK, a container for used nuclear fuel.
A CASK is a special container that transports and stores spent nuclear fuel. Since spent nuclear fuel steadily emits strong radiation and high heat, cask is a product that requires special design and manufacturing technology to convey and store it.
The special container will be five meters high and weigh more than 100 tons. The demand for CASKs is expected to rise in the nation from 2024, because the storage of Hanbit Nuclear Power Plant will be saturated in that year.
