1. A filter system, comprising:a dedicated piping system configured to connect between an interior of a containment housing a nuclear reactor or a ventilation outlet of the containment and a spent fuel storage water pool outside the containment, the dedicated piping system configured to fluidly communicate any atmospheric effluent to be released from inside of the containment through the spent fuel storage water pool, the dedicated piping system comprising an outlet in a lower portion of the spent fuel storage water pool;one or more valves connected to the dedicated piping system, the one or more valves configured to control a release of the atmospheric effluent to be released;a chemical injection system configured to release a chemical into the spent fuel storage water pool to facilitate a reaction with the atmospheric effluent to be released to substantially neuter any deleterious environmental impact of the atmospheric effluent to be released, the chemical injection system comprising a chemical injection header;a control system connected to one or more of the chemical injection system and/or the one or more of the valves and configured to control the release of the chemical and/or the release of the atmospheric effluent; anda sparger connected to the outlet of the dedicated piping system, the chemical injection header supported above the sparger within the spent fuel storage water pool;wherein the outlet in the lower portion of the spent fuel storage water pool is configured to release the atmospheric effluent to the spent fuel storage water pool through the sparger; andwherein the chemical injection system is configured to release the chemical into the spent fuel storage water pool through the chemical injection header. 2. The filter system of claim 1 wherein the dedicated piping system includes a check valve configured to prevent spent fuel storage pool water from being drawn into the containment. 3. The filter system of claim 1 wherein the control system includes a manually actuated, remotely operated valve in the dedicated piping system, the manually actuated, remotely operated valve being configured to isolate the atmospheric effluent from the spent fuel storage water pool under normal operating conditions, unless actuated. 4. The filter system of claim 3 wherein, the manually actuated, remote operated valve is configured in the dedicated piping system to be in parallel with a passively operated valve structured to release the atmospheric effluent to the spent fuel storage water pool if a pressure is sensed within the containment in excess of a given pressure. 5. The filter system of claim 1 wherein the chemical injection header and the sparger are supported within the spent fuel storage water pool at an elevation below a level that is used to transfer fuel into and out of the spent fuel storage water pool. 6. A filter system, comprising:a piping system configured to couple a ventilation outlet of a containment housing a nuclear reactor and a spent fuel storage water pool outside the containment, the piping system configured to fluidly communicate atmospheric effluent from the containment to the spent fuel storage water pool, the piping system comprising an outlet in a lower portion of the spent fuel storage water pool;a valve system configured to control a release of the atmospheric effluent from the containment to the spent fuel storage water pool;a chemical injection system configured to release a chemical into the spent fuel storage water pool to facilitate a reaction with the atmospheric effluent, the chemical injection system comprising a chemical injection header;a control system configured to control:the release of the chemical from the chemical injection system; andthe release of the atmospheric effluent from containment to the spent fuel storage water pool; anda sparger connected to the outlet of the piping system, the chemical injection header supported above the sparger within the spent fuel storage water poolwherein the outlet in the lower portion of the spent fuel storage water pool is configured to release the atmospheric effluent to the spent fuel storage water pool through the sparger; andwherein the chemical injection system is configured to release the chemical into the spent fuel storage water pool through the chemical injection header. 7. The filter system of claim 6 wherein the chemical injection header and the sparger are supported within the spent fuel storage water pool at an elevation below a level that is used to transfer fuel into and out of the spent fuel storage water pool. 8. A filter system, comprising:a piping system configured to couple a ventilation outlet of a containment housing a nuclear reactor and a spent fuel storage water pool outside the containment, the piping system configured to fluidly communicate atmospheric effluent from the containment to the spent fuel storage water pool, the piping system comprising an outlet in a lower portion of the spent fuel storage water pool;a valve system configured to control a release of the atmospheric effluent from the containment to the spent fuel storage water pool;a chemical injection system configured to release a chemical into the spent fuel storage water pool, the chemical injection system comprising a chemical injection header;a control system configured to control at least one of:the release of the chemical from the chemical injection system; andthe release of the atmospheric effluent from containment to the spent fuel storage water pool via the valve system; anda sparger connected to the outlet of the piping system, the chemical injection header supported above the sparger within the spent fuel storage water poolwherein the outlet in the lower portion of the spent fuel storage water pool is configured to release the atmospheric effluent to the spent fuel storage water pool through the sparger; andwherein the chemical injection system is configured to release the chemical into the spent fuel storage water pool through the chemical injection header. 9. The filter system of claim 8 wherein the chemical injection header and the sparger are supported within the spent fuel storage water pool at an elevation below a level that is used to transfer fuel into and out of the spent fuel storage water pool.
