For example, at the Indian Point nuclear power plant, unintended releases of tritium through a crack in the spent fuel pool concrete support wall may have been the cause of the elevated levels of tritium in groundwater in the area immediately surrounding the plant's spent fuel pool. In another instance, at the Braidwood nuclear power plant, unintended releases of tritium from a number of vacuum breaker valves at the plant caused elevated levels of tritium in groundwater in unrestricted, public areas.
