The 1B and 2B trains of Nuclear Service Wa … The 1B and 2B trains of Nuclear Service Water Systems (Raw Water Nuclear RN) were declared inoperable on 1/18/11 at 0423 EST due to fouling of the respective suction strainers when aligned to the Standby Nuclear Service Water Pond (SNSWP).</br>Tech. Spec. 3.0.3 was entered at 1110 EST on 1/20/11 due to the lack of reasonable assurance of operability pertaining to 1A and 2A RN trains in the event of a potential realignment to the SNSWP due to a seismic event.</br>The licensee plans to reduce power and place both Units in Mode 5.
