| ENS 53573 | 30 August 2018 09:58:00 | This is a concurrent report of a 24-hour report that was made to the Tennessee Department of Environment and Conservation (TDEC) regarding an unauthorized storm water discharge. As permitted by the State of Tennessee, emulsified vegetable oil was being injected into ground water wells located on the North Site of NFS property. At approximately 11:00 (EDT), Environmental Safety was notified of a cloudy oil substance that was observed in the west storm water ditch. Injections were immediately ceased and immediate corrective actions were implemented. Oil absorbent pads and socks were deployed and samples were collected. Before noon on 8/29/2018, the cloudy substance was observed at the discharge of the storm water ditch into Martins Creek. Because of the discoloration observed at the entrance to Martins Creek, this event required a 24-hour notification to TDEC (made at 16:15 on. 8/29/18) and a five day written report will be submitted. Analysis of the grab samples indicated no radioactive material release. The licensee notified the NRC Resident Inspector. |
| ENS 53384 | 4 May 2018 15:40:00 | This is a concurrent report of a 24-hour report that was made to the state of Tennessee regarding a break in the main fire water loop due to construction activities. The fire loop is fed by city water. The fire water pipe break was isolated by closing isolation valves upstream of the break. A portion of the water and dirt from the excavation flowed into a nearby storm water drainage system. This drainage system has a storm gate which was closed prior to the event to contain the dirt and water. The dirt is still contained in the storm water system located within the protected area of NFS. The dirt is currently being removed from the storm water system. The storm gate will remain closed until the dirt removal activity has been completed. Potential health and safety consequences to the workers, the public and the environment: "There are no actual safety consequences to workers, the public, or the environment. The potential consequence was a slightly elevated but less than the 10 CFR 20 Table 2 limits of contaminated liquid effluent from a construction accident. The licensee notified the NRC Resident Inspector. Fire watches have been established for the areas affected by the fire loop break. No criticality controls were affected by this event. |
