Title | Failure to Reduce the Free Water in a Class A Unstable Resin Disposal Package to Less than 0.5 Percent of Waste Volume |
Description | The inspectors reviewed a self-revealing, non-cited violation of Technical Specification 5.4.1.a, Procedures, for the licensees failure to follow their Process Control Program as implemented by their solid radioactive waste system procedures. Specifically, the licensee failed to reduce the free standing liquid in a condensate filter demineralizer
resin disposal package (Liner 14-033-L) to less than the required 0.5 percent of the tota waste volume. Corrective actions included retrieving the packages from waste shipment 14-32, testing each liner for free standing liquid content, and removing additional water as necessary. The licensee documented this issue in their corrective action program as Action Requests 00316555 and 00316676. The failure to follow the Process Control Program, resulting in the inadequate dewatering of radioactive waste liner contents, was a performance deficiency. The inspectors determined that the performance deficiency was more than minor, because it adversely affected the Public Radiation Safety cornerstone objective to ensure adequate protection of public health and safety from exposure to radioactive materials released in the public domain Specifically, the failure to ensure that the free standing liquid in the radioactive waste liner shipped to US Ecology did not exceed 0.5 percent of the total waste volume subjected the disposal facility to the possibility of improper handling of the waste. Using Inspection Manual Chapter 0609, Appendix D, Public Radiation Safety Significance Determination Process, dated February 12, 2008, the inspectors determined the violation was of very low safety significance (Green) because: (1) radiation limits were not exceeded, (2) there was no breach of the package during transit, (3) there were no Certificate of Compliance issues, and (4) the low level burial ground nonconformance did not involve a 10 CFR 61.55 waste under-classification. The inspectors determined that the finding has a design margin crosscutting aspect in the area of human performance, because the licensee failed to operate and maintain the radioactive waste dewatering system within the vendor design margins when changes were made to the operating procedures [H.6]. |
