| Title | Reactor Coolant Leakage Outside of Containmemt |
| Event Description | This is an 8-hour notification being made to report exceeding the design basis for the reactor coolant leakage outside of containment. The event is being reported under paragraph (b)(3)(v) of 10CFR50.72.
On 12/05/04 at 1015 the control room was notified of leakage from a gasketed flange area on the 11 Residual Heat Removal Heat Exchanger. The leak rate has been conservatively quantified at 0.68 gpm, which is greater than the UFSAR limit of 2100 cc/hr (0.009 gpm) for ECCS leakage outside containment. With leakage greater than the UFSAR allowed limits, GDC-19 limits for control room habitability cannot be assured. Actions are in progress to torque the flange bolts to reduce the leakage. The licensee has notified the NRC Resident inspector of this event. Salem Unit One is in Mode 4 with the Residual Heat Removal system in service removing reactor decay heat. No ECCS system actuations occurred. No one was injured as a result of the leak. |
