Study on the fuel balance of a DT reactor

The tritium balance in a DT fusion reactor is discussed in this paper. It is pointed out in this discussion that tritium balance in a fusion reactor is largely influenced by such uncertainties as plasma vessel effect, module effect and recovery efficiency of bred tritium required to estimate the overall tritium recovery efficiency and such uncertainties as overall burning efficiency of tritium in the plasma vessel, tritium trapping ratio at the first wall, loss due to β-decay of tritium inventory and designated reactor base tritium breeding ratio required to decide (β)overall to decide tritium balance.
