instantly exploding and, before it has time to expand, some fustion of D and T nuclei takes place, forming the gas Helium, He. Fast moving neutrons are released which carry most of the energy produced. This process is called 'inertial confinement fusion' (ICF).
3 is solved by surrounding the vessel with liquid lithium (Li), a light, highly reactive metal like sodium, which traps the neutrons, turning their energy into heat, used to make steam to drive turbines and produce electricity.
4 is also solved here, as nuclear reactions between Li and the neutrons will 'breed' more T.
Problem 1 is the least worry of fusion researchers at the moment, but is nevertheless not simple. The apparatus must be strong enough to withstand the ten or so explosions per second needed to produce a useful amount of energy. without leaking.

A failure of cooling would not affect the supply of fuel at all, unlike in a fission reactor with the danger of a 'meltdown' Leakage of liquid Li would be dangerous, though, with the possibility of fire and release of radioactive T. Though T gives out less powerful radiation and for a shorter time than U or Pu being a gas it can easily enter the lungs and, being chemically identical to H, it can be incorporated in water and enter the tissues of the body, in both cases being best placed to cause mutilations and cancers.
The danger may be low globally but could be high for workers in such establishments, or for nearby residents. In any case, fusion reactors would appear to be safer than fission reactors. but since at present no one has succeeded in getting out more than a few per cent of the energy they put in to start a fusion reaction. commercial fusion power seers raiber a long may € = 5= dot tee IF light-skinned people in sunny lands learn to their cost; and as we shall all learn, if we destroy the nanno lover!
