Toshiba's efforts to reduce refueling outage duration in nuclear power plants

摘要

Improvement of refueling outage technology for nuclear power plants is an important aspect of improving plant availability. In particular, ways of shortening the duration of refueling outage are especially important due to the need for costreductions following the revision of the Electricity Utilities Industry Law.As a plant manufacturer, Toshiba has an abundance of experience in refueling outages. We have therefore been making many presentations to utilities on methods to reduce refueling outage duration while maintaining plant safety; namely, improving facilities and equipment, improving the work sequence, and other duration-shortening technologies.
