Tritium transport permeation and control
WebThe source permeator (SP) delivers atomic hydrogen (H, D, and T) from a gas-phase reservoir into the PbLi via a permeable dense metal membrane. A modular system and a fixed SP system are presented. In the modular design, PbLi flows through the inside of a tubular membrane, and gas-phase hydrogen is introduced on the outside of the membrane. WebOct 7, 2014 · II. Tritium transport model 1. Tritium production rate In graphite moderated high temperature reactors, tritium is produced by ternary fissions and by activation reactions with graphite impurities (6Li) or with control materials (10 B). Tritium is also provided by activation reactions with nuclides which
