GNF-A's (Global Nuclear Fuels - Americas) … GNF-A's (Global Nuclear Fuels - Americas) Fuel Manufacturing Operation maintains a safe geometry Radwaste accumulation tank to receive certain liquid discharges from operations. During the annual shutdown work activities and routine inspections, an accumulation of material was identified in a safe geometry Radwaste accumulation tank.</br>The accumulation appears to have occurred due to reduced recirculation flow, an engineered feature that mixes the contents of the tank as part of a density control. The accumulation of material is an indication that the tank density control had degraded.</br>Plant operations attempted to remove and quantify the material per normal requirements. On 4/12/18 at approximately 1900 (EDT), GNF-A determined that the material could not be quantified in a timely manner.</br>In the absence of quantification, GNF-A has conservatively determined that this condition is a failure to meet performance requirements and is therefore reporting it within 24 hours of discovery pursuant to Part 70 Appendix A (b)(2).</br>Additional controls on the tank geometry remained intact and at no time was an unsafe condition present. In addition, there are no sources that could result in a rapid addition of uranium to the system.</br>Additional corrective actions, extent of condition, and extent of cause are being investigated.</br>The licensee will be notifying their NRC Program Manager (Vukovinsky), the Radiation Protection Section at North Carolina Department of Health and Human Services, and Hanover County Emergency Management Agency.anover County Emergency Management Agency. +
