Tritium can be stored as a solid metal tritide. You can use several different metals but titanium seems to offer the best cost/benefit. A 7" diameter cylinder 16" high weighing 35 pounds can store 300 grams of tritium safely for 5 years (without releasing any decay helium). It's totally stable at room temperature, stable in water, and needs to be heated to ~600C to add/remove tritium. The decay heat output of 300g of tritium is ~100 watts, so the vessel should probably have some heatsinks and be ventilated. About 300g of tritium will be required per day to produce 800 MW of power. https://inis.iaea.org/collection/NCLCollectionStore/_Public/... |
