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

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.

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.
