CONCEPTUAL STUDIES ON HIGH GAIN LASER FUSION REACTOR WITH MAGNETICALLY GUIDED LI FLOW

Abstract

A concept of a D-T fusion laser reactor (SENRI-I) with magnetically guided inner Li flow is presented. It is assumed that input laser energy is 1∼5 MJ and pellet gain is 1000∼200. The scaling law of pellet gain is examined. The inner Li flow is used as a first wall protector, a coolant and a tritium breeder. It is found that flow shape and velocity are well controlled and the disassembling is suppressed by magnetic field pressure. One dimensional neutron transport calculations show that tritium breeding ratio is ∼ 1.6.
