Doosan Heavy exports casks to store spent nuclear fuel to U.S.

SEOUL, March 25 (Yonhap) – South Korea’s leading power equipment manufacturer, Doosan Heavy Industries & Construction Co., announced Thursday that it has provided a U.S. company with five vertical concrete barrels for the first time to store spent fuel.

Under the contract with Nuclear Assurance Corp. (NAC), a US provider of nuclear fuel cycle technology and consulting solutions, supplied the drums to Doosan Heavy.

However, Doosan Heavy did not reveal the value of the deal, citing a confidentiality agreement with NAC.

Doosan Heavy is expected to provide two portable storage canisters, a key component of the dry storage kegs, in June under a separate contract with the US company.

The dry storage barrels will be used to store spent fuel at the Three Mile Island Nuclear Power Plant in Pennsylvania, USA, Doosan Heavy said.

The concrete barrel is 5.7 meters high, 3.4 meters in diameter and weighs 100 tons.

Export of the dry storage drums is significant as Doosan Heavy first paved the way for entering the overseas spent nuclear fuel drum market, the company said.

Since 2015, Doosan Heavy has been developing spent fuel barrels with the technological support of NAC.

The company has sought approval of the designs for its kegs from the US Nuclear Regulatory Commission (NRC), an independent agency that regulates commercial nuclear power plants and other uses of nuclear material.

Doosan Heavy predicts it could get approval in June.
