On February 23, 2017, a containment visual … On February 23, 2017, a containment visual inspection was performed to identify the source of elevated RCS (Reactor Coolant System) leakage. A leak was identified at the nozzle connection of the boron injection line to 2D RCS cold leg at 1922 (EST). It was determined that the leak cannot be isolated and is considered RCS pressure boundary leakage. Unit 2 entered TS LCO 3.4.13, RCS Operational Leakage, Condition B, for the existence of pressure boundary leakage.</br>This event is reportable in accordance with 10CFR50.72(b)(2)(i) (4 hours) for 'initiation of plant shutdown required by Technical Specifications' and 10CFR50.72(b)(3)(ii)(A) (8 hours) for 'any event or condition that results in the condition of the nuclear power plant, including its principal safety barriers, being seriously degraded.'</br>The unit will shutdown and repairs will be performed in Mode 5.</br>This condition has no impact on public health and safety.</br>The licensee has informed the NRC Resident Inspector.</br>At the time of the event notification, Unit 2 was at 33 percent power. Unidentified RCS leakage is estimated at 0.28 gpm. Unit 2 is expected to be in Mode 3 by 0122 EST on 02/24/2017. Unit 1 is not affected by this event.17. Unit 1 is not affected by this event. +
