Frozen water in the standpipe could result in the restricted flow or complete loss of water supply to the sprinkler heads. The PSS declared the system inoperable and TSR LCO 2.4.4.5 actions were initiated to remove the system from service. </br>Freeze out of the system was due to extremely low outside ambient temperatures and a faulty filter room thermostat. The event is reportable as a 24 hour event, as required by 10 CFR 76.120(c)(2)(i); An event in which equipment is disabled or fails to function as designed when the equipment is required by a TSR to prevent releases, prevent exposures to radiation and radioactive materials exceeding specified limits, mitigate the consequences of an accident, or restore this facility to a pre-established safe condition after an accident. The equipment was required by TSR to be available and operable and no redundant equipment was available to perform the required safety function.</br>The faulty filter room thermostat was replaced, and the High Pressure Fire Water System was declared operable at 1500 CST. Operations personnel took compensatory measures by checking similar indicators in all process buildings.</br>The Senior NRC Resident Inspector has been notified of this event.Inspector has been notified of this event. +
