l The Site Emergency class includes Alert conditions where the plant personnel have been initially unsuccessful in restoring the facility to a safe shutdown condition (e.g., the fire has now continued for more than 10 minutes and has now caused loss of function of

, subsequent additional malfunctions have occurred Te.g., a transient l occurs during the time when plant alarms are inoperabfe). The Site l Emergency class is more severe than the Alert class because
