REFUELING WATER STORAGE TANK LEVEL LOWER THAN REQUIRED
"While performing a purification on the Unit 2 Refueling Water Storage Tank (FWST), it was discovered that the single train system was inoperable due to the level being less than the required volume per SR [Surveillance Requirement] 3.5.4.2. The condition was discovered on 8/18/19 at 1700 [EDT]. The FWST level was restored to greater than the required volume per SR 3.5.4.2 at 1744 on 8/18/19. This condition is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(v)(D) for an event or condition that could have prevented the fulfillment of a safety function. There was no impact on the health and safety of the public or plant personnel.
"The NRC Resident Inspector has been notified."
