Abstract :
An approach to augmenting the energy multiplication of fusion reactor blankets is proposed. It consists of including, in the blanket, a high-Q element in a fluid state, thereby allowing removal of its contribution to afterheat in case of a loss-of-coolant accident (LOCA). The two general design approaches proposed are including Mn or Cr-containing particles within a gas coolant, and using MnF2 or CrF2 in a molten salt system. A preliminary feasibility study indicates that both approaches could be practical, so that a more thorough assessment is recommended
