| Title | Failure to Minimize Void Spaces in a Radioactive Waste Package |
| Description | Green. The team reviewed a self-revealed non-cited violation of 10 CFR 61.56(a)(3) for the licensees failure to assure that void spaces within the waste packages were reduced to the extent practicable. Specifically, a ship ment of dry active waste sent to US Ecology in May 2016 arrived at the disposal facility with voids in excess of 15 percent of the total waste volume, contrary to the requirements of US Ecologys Radioactive Material License WN-I019-2, License Condition No. 23. Corrective actions included inspecting the other containers from waste shipment No.16-27 and testing each container for voids. The licensee documented this issue in their corrective action program as Action Request 352217 and performed an apparent cause evaluation. The failure to ship radwaste for disposal without reducing void spaces to the extent practicable was a performance deficiency. The team 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 void spaces were removed in the radwaste container shipped to US Ecology subjected the disposal facility to the possibility of improper disposal of the waste, in that, the package was susceptible to stability issues. Using NRC Inspection Manual Chapter 0609, Appendix D, Public Radiation Safety Significance Determination Process, the violation was determined to be 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 finding has a cross-cutting aspect in the area of human performance, associated with teamwork, because individuals and work groups failed to communicate and coordinate their activities within and across organizational boundaries to ensure nuclear safety is maintained [H.4]. |
