(This) was confirmed to be the cause for an invalid torus high water level alarm and a HPCI (High Pressure Core Injection) pump suction swap. This resulted in the HPCI suction swapping from its normal lineup, condensate storage tank (CST), to the torus as designed. Once actuated the suction swap occurred as designed. The cause was attributed to the close proximity between an individual descending/ascending the fixed ladder and the affected sensing line in conjunction with a loose tubing restraint which made the line more sensitive to being bumped. After confirming that the actuation on high torus level was invalid, HPCI suction was realigned to the CST.</br>The HPCI pump suction was subsequently realigned to the CST and the loose tubing restraints were tightened.</br>The licensee notified the NRC Resident Inspector.ensee notified the NRC Resident Inspector. +
