| Title | Failure to Follow Station Guidance on Control of Scaffolding |
| Description | Green . The inspectors identified a non-cited violation of Technical Specification 5.4, Procedures, for the licensees failure to follow station maintenance procedures related to the control of scaffolding in the reactor building. Specifically, the licensee installed scaffolding less than two inches from safety -related containment unit cooler HVR -UC1 B without completing an engineering evaluation. The licensee entered this issue into their corrective action program as Condition Report CR- RBS -2016- 07963 . Corrective actions included removing the scaffolding. The licensees installation of scaffolding within two inches of a safety -related containment unit cooler , without completing an engineering evaluation, was a performance deficiency. The performance deficiency was more than minor, and therefore a finding, because it was associated with the equipment performance attribute of the Mitigating Systems Cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, containment unit cooler HVR- UC1B was rendered inoperable by the incorrectly installed scaffolding and remained inoperable until the scaffolding was removed. The inspectors screened the finding in accordance with NRC Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) for Findings At -Power. Using NRC Inspection Manual Chapter 0609, Appendix A, Exhibit 2, Mitigating Systems Screening Questions, the inspectors determined the finding to be of very low safety significance ( Green) because the finding did not represent an actual loss of function of one or more trains of safety-related equipment for greater than its technical specification allowed outage time. This finding has a cross -cutting aspect in the area of human performance, avoid complacency , because the licensee failed to recognize and plan for the possibility of mistakes, latent issues, and inherent risks, even while expecting successful outcomes . Specifically, the station failed to implement appropriate error reduction tools when it did not perform and document Procedure EN -MA -133, Control of Scaffolding, Attachments 9.5 and 9.6 , which could have prevented the scaffolding construction error [H. 12]. |
