A conceptual design of light ion beam fusion reactor — UTLIF(2)

Abstract UTLIF(2) is a conceptual design study on a light ion beam driven fusion reactor based on a concept of rod-bundle blanket. Survivability and maintainability of the first wall and the blanket are regarded as of major importance in the design. The blanket rod is composed of a thick tube which has enough stiffness, a thin wrapping wall which receives high heat flux, and liquid lithium which breeds tritium and removes generated heat. The rod can be pulled out from the outside of the reactor vessel, hence the replacement is very easy. Nuclear, thermal and structural analyses have been made and the performance of the reactor has been shown to be satisfactory. Safety and reliability of the plant have been discussed and the challenge before us has been revealed. This paper also includes a fireball analysis, an outline of target design and design of a tritium handling system.
