| Title | Offsite Notification to Federal Agency Regarding Excavation Activities |
| Event Description | {{#Wiki_filter:On April 16, 2011, a suspected buried pipe leak was identified in the plant yard. Subsequent investigation revealed that the source of the water was a leak in the Unit 1 Condenser Circulation Water (RC) intake pipe. In order to perform a repair, the ground in the vicinity of the pipe, including the toe of the dike berm, required excavation. McGuire Nuclear Station (MNS) site personnel recognized that excavating into the dike would require Federal Energy Regulatory Commission (FERC) involvement. Duke Hydro was contacted, and confirmed that the dike across the MNS intake is an extension of the Cowans Ford Dam and would require FERC authorization to dig into it. On the morning of April 20, 2011, Duke Hydro personnel contacted the FERC engineer assigned to Duke Energy's Cowans Ford Hydroelectric Development to seek FERC authorization for the excavation. Duke Hydro hosted a conference call later that same morning between FERC's Atlanta Regional Office and MNS site personnel to discuss the details of the situation and planned repairs. FERC later dispatched their personnel to the site to observe the repair effort.
10 CFR 50.72(b)(2)(xi) requires a 4-hour notification to be made for any event or situation, related to the health and safety of the public or on-site personnel, or protection of the environment, for which a news release is planned or notification to other government agencies has been or will be made. �50.72(b)(2)(xi) further states that such an event may include an onsite fatality or inadvertent release of radioactively contaminated materials. Although a phone call to an outside government agency (FERC) was made, Duke Energy made the decision at the time to not make a 4-hour notification to the NRC. This decision was based on the belief that 1) the RC leak and impact on the dike had no safety significance, 2) there were no concerns regarding protection of the environment, and 3) the situation did not involve an on-site fatality or an inadvertent release of radioactively contaminated materials. However, based upon how the matter was characterized in discussions between NRC and FERC, the NRC is not in agreement with the Duke Energy position. Therefore, the purpose of this phone call is to provide the necessary 10 CFR 50.72(b)(2)(xi) notification retroactively. }} |
