The continuing delay in the U.S. Department of Energy's Yucca Mountain and monitored retrievable storage spent-fuel disposal and storage programs has prompted U.S. utilities to consider expanding on-site storage of spent reactor fuel. Long-term, on-site storage has certain advantages to U.S. utilities since it eliminates the need for costly and difficult shipping and puts control of the spent fuel completely under the direction of the owner-utility. AECL Technologies (AECL), through its research company and Canada deuterium uranium (CANDU) engineering services division, has been developing on-site storage for Canadian heavy water nuclear plants for almost 20 yr. AECL has developed a design for a dry storage unit, designated MACSTOR (modular air-cooled storage), that can accommodate U.S. light water reactor (LWR) fuel elements and could become a candidate for the U.S. market. This paper describes MACSTOR and its evolution from the original silos and CANSTOR system that was developed and used in Canada. These systems are subject to regulatory controls by the Atomic Energy Control Board of Canada and have proven to be safe, convenient, and cost effective.
