| Title | Potential Leak from a Pipe Could Result in Damage to Both Trains of Electrical Power Systems |
| Event Description | This is a non-emergency notification.
At approximately 10:40 AM on October 8, 2014, with the Harris Nuclear Plant operating at 100% power, a condition was discovered where a potential leak from a pipe supplying water to the fire suppression system in the diesel fuel oil storage tank building could result in damage to equipment in both trains of the onsite electrical power system. Neither the leak from the piping nor the damage to equipment actually occurred, so there are no actual safety consequences and no impact to public health and safety or the environment due to this condition. The condition was discovered during a Harris staff evaluation in the corrective action program. The condition will be fully investigated, including the extent of condition, and corrective actions taken to resolve the issue. Compensatory actions have been taken as interim actions to ensure safety systems are not impacted by the potential pipe leak. This event is reportable per 10 CFR 50.72(b)(3)(v). The NRC Resident Inspector has been notified. |
