Basis An Operational Basis Earthmake (0.11G) may cause damage to some portions of the site but should not affect the ability of safety functions to operate. Method of detection is validated by a reliable source (e.g. Lamont-Doherty Geological Observatory: (914)359-2900). The OBE is as determined from 10CFRlOtD. The EAL's addressing intake water level both high and low are escalations of a worsening condition cited in the U.E. class. The level's address the Nureg concern for approaching design conditions where the heat sink's effectiveness may be reduced and subsequently lost. EAL # 5 is based on the assumption that a tornado striking (touching down)) the facility (within the protected area boundary) may have potentially damaged plant structures containing function or systems required for safe shutdown of the plant. If such damage is confirmed, the event may be escalated to a Site Area Emergency.
