1. A nuclear reactor installation comprising: a. a reactor vessel adapted to contain nuclear fuel therein, said vessel being adapted for operation with said installation whereby it will become radioactively contaminated in the course of its operative life; b. a shield structure including: 1. a reactor chamber for housing the reactor vessel during its operative life; and 2. a burial chamber beneath the reactor chamber in communicating relationship with the reactor chamber and capable of receiving the reactor vessel at the expiration of its operative life for at least a time sufficient to permit the radioactive contamination to decay to acceptable levels; c. a platform supporting the reactor vessel within the reactor chamber, said platform being capable of permitting downward movement of said reactor vessel into the burial chamber; d. means for supporting said platform; e. means for withdrawing support from said platform; and f. means for withdrawing the reactor vessel from the reactor chamber to the burial chamber at the expiration of said operative life.
2. a burial chamber beneath the reactor chamber in communicating relationship with the reactor chamber and capable of receiving the reactor vessel at the expiration of its operative life for at least a time sufficient to permit the radioactive contamination to decay to acceptable levels; c. a platform supporting the reactor vessel within the reactor chamber, said platform being capable of permitting downward movement of said reactor vessel into the burial chamber; d. means for supporting said platform; e. means for withdrawing support from said platform; and f. means for withdrawing the reactor vessel from the reactor chamber to the burial chamber at the expiration of said operative life.
2. A nuclear reactor installation according to claim 1 wherein: a. said platform supporting the reactor vessel within the reactor chamber is adapted for downward movement into the burial chamber at the expiration of said operative life; and b. said means for withdrawing the reactor vessel from the reactor chamber to the burial chamber includes an elevator drive operatively connected to said platform whereby at the expiration of the operative life of the reactor vessel the elevator drive may be activated to cause downward movement of said platform and said exhausted vessel into the burial chamber.
2. an auxilliary entombment area adjoining the primary entombment area for subsequently receiving the exhausted reactor vessel.
2. at least one removable support column positioned within the burial chamber for supporting the platform during the operative life of the reactor vessel in a position defining the floor of reactor chamber; and b. each shaped explosive charge is deployed on each support column.
2. at least one explosive charge positioned such that upon detonation said support structure is destroyed thereby allowing the reactor vessel to drop under the influence of gravity into the burial chamber.
3. A nuclear reactor installation according to claim 2 wherein: a. said burial chamber includes:
4. A nuclear reactor installation according to claim 3 wherein: a. said elevator drive comprises:
5. A nuclear reactor installation according to claim 4 including: a. removable support means positioned within the burial chamber for supporting the platform during the operative life of the reactor vessel in a position defining the floor of the reactor chamber; and b. an access way leading into the lower portion of the burial chamber to permit entrance into the burial chamber for the purpose of removing said support means in preparation for entombment of said exhausted reactor vessel.
6. A nuclear reactor installation according to claim 5 including: a. an access way leading into the upper portion of the burial chamber through which sealing material may be poured to permanently seal the burial chamber.
7. A nuclear reactor installation according to claim 6 wherein: a. said reactor chamber is located above ground level, and B. said burial chamber is located below ground level.
8. A nuclear reactor installation according to claim 1 wherein: a. said means for withdrawing the reactor vessel from the reactor chamber to the burial chamber includes:
9. A nuclear reactor installation according to claim 8 wherein: a. each explosive charge is a shaped explosive charge capable of channeling the explosive force in a predetermined direction.
10. A nuclear reactor installation according to claim 9 wherein: a. said support structure includes:
11. A nuclear reactor installation according to claim 9 wherein: a. said reactor is located above ground level; and b. said burial chamber is located below ground level.
12. A nuclear reactor installation according to claim 11 including: a. secondary shaped explosive charges situated exteriorly of the burial chamber for the purpose of permanently sealing the burial chamber after removal of the reactor vessel into the burial chamber.
13. A nuclear reactor installation according to claim 12 including: an access way leading into the lower portion of the burial chamber to permit entrance into the burial chamber for purpose of deploying each explosive charge.
14. A nuclear reactor installation according to claim 12 including: a. an access way leading into the upper portion of the burial chamber through which sealing material may be poured to permanently seal the burial chamber.
15. A a for disposing of a nuclear reactor vessel supported in a reactor chamber at the expiration of its operative life comprising the steps of: a. withdrawing support from the reactor vessel; and b. withdrawing the reactor vessel downwardly from the reactor chamber housing the a vessel during its operative life into a burial chamber beneath the reactor chamber and communicating with the reactor chamber, utilizing at least one explosive charge positioned such that upon detonating said charge, the structure supporting the vessel in the reactor chamber is destroyed to thereby allow the vessel to drop under the influence of gravity into the burial chamber.
16. The method according to claim 15 wherein the explosive charges are shaped explosive charges capable of channeling the explosive forces in a predetermined direction.
17. The method according to claim 16 including the step of: a. permanently sealing the burial chamber.
18. The method to claim 17 wherein a. sealing of the burial chamber is effected by detonating shaped explosive charges deployed exteriorly of the burial chamber.
19. A method for disposing of a plurality of nuclear reactor vessels supported in a reactor chamber in succession at the expiration of the operative life of each vessel including the steps of: a. withdrawing support from each reactor vessel; b. withdrawing the reactor vessel downwardly from the reactor chamber housing the vessel during its operative life into a burial chamber beneath the reactor chamber; c. moving each exhausted reactor vessel subsequent to placement thereof into the burial chamber out of the path of downward movement of the reactor vessel into the burial chamber; and d. reloading the reactor chamber with a new reactor vessel.
20. The method according to claim 19 wherein: a. movement of each exhausted reactor vessEl into the burial chamber is accomplished by lowering the platform supporting the vessel in the reactor chamber during its operative life into the burial chamber.
21. The method according to claim 20 including the step of: a. raising the platform into its initial position within the reactor chamber prior to reloading the reactor chamber with a new reactor vessel.
