Injecting reactant into a spent fuel pool to react with radioactive effluent released into the pool from a nuclear reactor containment

1. A method of releasing an atmospheric effluent within a nuclear containment to an atmosphere surrounding the nuclear containment, the nuclear containment being adjacent to an associated spent fuel pool that is located outside the nuclear containment, the method comprising:

sensing a pressure buildup within the nuclear containment;

routing a portion of the atmospheric effluent through the spent fuel pool when a pressure buildup within the nuclear containment reaches a preselected value, wherein the routing includes introducing the atmospheric effluent into water in the spent fuel pool through a sparger supported near or at a bottom of the spent fuel pool; and

releasing a chemical into the spent fuel pool, based on the routing, to facilitate a reaction with the atmospheric effluent to substantially neuter any deleterious environmental impact of the atmospheric effluent, wherein the releasing comprises releasing the chemical into water within the spent fuel pool at an elevation near the bottom of the spent fuel pool proximate to the sparger.

2. The method of claim 1 , wherein the routing and the releasing are performed at approximately the same time.

3. A method of releasing effluent within a nuclear containment into a spent fuel pool, comprising:

sensing a pressure within the nuclear containment;

routing a portion of the effluent into the spent fuel pool, based on the pressure reaching a threshold, wherein the routing includes introducing the portion of the effluent into water in the spent fuel pool through a sparger supported proximate to the bottom of the spent fuel pool; and

releasing a chemical into the spent fuel pool, based on the portion of the effluent being routed to the spent fuel pool, wherein the releasing comprises releasing the chemical into the spent fuel pool at a location proximate to the sparger, wherein the location is proximate to the bottom of the spent fuel pool.

4. The method of claim 3 , wherein the routing and the releasing are performed at approximately the same time.

5. The method of claim 3 , wherein the location is at an elevation above the sparger.

6. The method of claim 3 , further comprising controlling a release of the effluent from the nuclear containment.

7. The method of claim 3 , further comprising controlling a release of the chemical into the spent fuel pool.

8. A method of releasing effluent within a nuclear containment into a spent fuel pool, comprising:

routing a portion of the effluent from the nuclear containment toward the spent fuel pool;

releasing, via a sparger, the routed effluent into the spent fuel pool at a first location, wherein the first location is near the bottom of the spent fuel pool; and

releasing a chemical into the spent fuel pool at a second location proximate to the first location, based on the routed effluent being released into the spent fuel pool.

9. The method of claim 8 , wherein the routing and the releasing the chemical are performed at approximately the same time.

10. The method of claim 8 , wherein the second location is at an elevation above the first location.

11. The method of claim 8 , further comprising controlling a release of the effluent from the nuclear containment.

12. The method of claim 8 , further comprising controlling a release of the chemical into the spent fuel pool.

13. The method of claim 8 , wherein routing the portion of the effluent from the nuclear containment toward the spent fuel pool comprises routing the portion of the effluent along a first path from the nuclear containment to the spent fuel pool, and wherein the method further comprises:

sensing a pressure within the nuclear containment; and

rerouting the effluent along a second path based on the pressure reaching a threshold, wherein the second path is different than the first path.

14. The method of claim 8 , further comprising preventing inventory of the spent fuel pool from being routed into the nuclear containment during a nuclear containment vacuum.

15. The method of claim 8 , further comprising preventing the nuclear containment from exceeding a maximum vacuum limit.
