Section: claims

1. A method of mitigating plasma disruption, comprising:magnetically confining plasma in a plasma vessel;storing cooled pellets; andinjecting the cooled pellets into the plasma vessel at a known velocity from a location that has an absence of a magnetic field from the plasma vessel. 2. The method of claim 1,wherein the cooled pellets are cooled to less than or equal to 40 kelvin (K). 3. The method of claim 2, wherein the stored cooled pellets are cooled to 10 kelvin (K). 4. The method of claim 2, the pellets comprise solid pellets. 5. The method of claim 2, comprising using hollow shell pellets as the pellets. 6. The method of claim 5, wherein each hollow shell pellet encapsulates a payload. 7. The method of claim 6, wherein the payload comprises granules or a porous material. 8. The method of claim 6, wherein the payload comprises lithium, lithium deuteride, beryllium, beryllium deuteride, boron, boron nitride, or tungsten. 9. The method of claim 2, wherein each pellet includes lithium. 10. The method of claim 1, comprising using a hollow shell encapsulating a payload as the pellets. 11. The method of claim 10, wherein the hollow shell comprises lithium, lithium deuteride, beryllium, beryllium deuteride, or boron nitride. 12. The method of claim 10, wherein the payload comprises lithium, lithium deuteride, beryllium, beryllium deuteride, boron, boron nitride, or tungsten. 13. The method of claim 2, wherein each pellet includes beryllium.
