Abstract

A large amount of T is used as a fuel in a fusion reactor, but its release to the environment is rigidly regulated to be quite low by law. In order to protect workers, the public, and the environment from radiation of T, it is very important to confine T safely. The first section explains basics of radiation protection and indicates specified values relating to T safety confinement such as dose limit. T has a property of permeating easily through even metals. Therefore, the T release to the environment is suppressed by multiple confinements system based on the concept of defense in depth. The multiple-confinement system has been adopted in many T handling facilities in the world and operated successfully for many years. The second section explains the concept and practical configuration of the multiple confinements system in the present T handling facilities and a fusion power plant. In the fusion power plant, various kinds of wastes contaminated by T would be generated. It is necessary to pay careful attention in handling of these T contaminated wastes. The third section explains the management and processing of the T contaminated wastes.
