| Title | Failure to Follow Procedure and Perform a Root Cause Evaluation to Assess the Causes of a Radwaste Shipping Event |
| Description | Green. The team identified a finding for the failure to follow the requirements of Procedure SWP-CAP-06, Condition Report Review, when determining the type of 6 cause evaluation required to assess the causes of the higher than expected dose rates on a radwaste container. Specifically, Procedure SWP-CAP-06 required that if an event has high risk and high uncertainty, the level of evaluation required is a root cause evaluation. However, the licensee failed to adequately assess the uncertainty associated with the causes of the event and performed an apparent cause evaluation rather than a root cause evaluation. The licensee entered this finding into the corrective action program as Action Request 360236. The failure to follow the requirements of Procedure SWP-CAP-06 when determining the type of cause evaluation required to assess the higher than expected dose rates on a radwaste container and performing an apparent cause evaluation instead of a root cause evaluation was a performance deficiency. The team determined that the performance deficiency was more than minor, and therefore a finding, because it was associated with the Public Radiation Safety Cornerstone attribute of program and process and adversely affected the 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 adequately assess the causes of the event left the licensee vulnerable to future radwaste processing and transportation errors of significance. Using NRC Inspection Manual Chapter 0609, Appendix D, Public Radiation Safety Significance Determination Process, the finding was determined to be of very low safety significance (Green). The finding has a cros s-cutting aspect in the area of problem identification and resolution, associated with evaluation, because the licensee failed to thoroughly evaluate the issue to ensure resolutions address causes and extent of conditions commensurate with their safety significance [P.2]. |
