Interfacing the Tandem Mirror Reactor to the Sulfur-Iodine Process for Hydrogen Production

摘要

The blanket is linked to the H sub 2 SO sub 4 vaporization units and SO sub 3 decomposition reactor with either sodium or helium. The engineering and safety problems associated with these choices are discussed. This H sub 2 SO sub 4 step uses about 90% of the TMR heat and is best close-coupled to the nuclear island. The rest of the process we propose to be driven by steam and does not require close-coupling. The sodium loop coupling seems to be preferable at this time. We can operate with a blanket around 1200 K and the SO sub 3 decomposer around 1050 K. This configuration offers double-barrier protection between Li-Na and the SO sub 3 process gases. Heat pipes offer an attractive alternate to provide an additional barrier, added modularity for increased reliability, and tritium concentration and isolation operations with very little thermal penalty.
