Doosan Heavy Industries and NAC International, Inc. form Technology Alliance on Development of CASK Storage for Spent Nuclear Fuel

Doosan and NAC are pleased to announce the signing of a cooperation agreement for the joint development of CASK, a spent nuclear fuel storage system. CASK is a special container standing some 5 meters tall and weighing over 100 tons that is designed to carry and store spent fuel. The storage system requires a special design and production technology for transportation and storage, and will be built to ensure protections from the intense levels of radiation and heat from the enclosed spent fuel.

CASK will be deployed in Korea in an effort to support spent fuel management of the Korean nuclear industry. According to the Public Engagement Commission on Spent Nuclear Fuel Management in Korea, the storage capacity for spent fuel of the Hanbit plant will reach its full capacity in 2024. As the demand for spent fuel storage systems is likely to increase, Doosan and NAC plan to develop the CASK and expand it as a new business line in the nuclear sector in the future. To date, no other Korean company has developed a design technology for a long-term storage system.

In attendance at the signing ceremony held at Doosan’s Seoul Office were officials from the two companies including CEO Kent Cole of NAC and Executive Vice President & CEO Habang Kim of Doosan’s Nuclear Business Group.
