| Title | Unanalyzed Scaffold Near Safety-Related Equipment |
| Description | A finding of very low safety significance and associated NCV of Technical Specifications (TS) 5.4, Procedures, was identified by the inspectors. The licensee constructed a scaffold storage rack adjacent to the Unit 1 Component Cooling Water (CCW) Surge Tank without a seismic evaluation. Specifically, contrary to 12MHP5021SCF00, Scaffolding Procedure, the seismic adequacy of the rack was not evaluated prior to construction. The rack was built several weeks before the Unit 1 Spring 2016 refueling outage (RFO) and was assessed by inspectors during the outage as part of walkdown of the area. The licensee removed the scaffold storage rack and entered the issue into their Corrective Action Program (CAP). The issue was greater than minor because it adversely affected the Protection Against External Factors attribute of the Mitigating Systems cornerstone, whose objective is to ensure the capability, reliability, and availability of systems that respond to initiating events to prevent undesirable effects such as core damage. Further, the inspectors determined examples 3.j and 3.k of IMC 0612 Appendix E, Examples of Minor Issues, applied as there was reasonable doubt concerning the operability of the CCW system with the as-found condition of the scaffold. The finding screened as Green, or very low safety significance, utilizing IMC 0609, Significance Determination Process. Specifically, a seismic evaluation later demonstrated that safety functions were maintained. The inspectors determined the finding had a cross cutting aspect of Work Management (H.5.). Specifically, the work management process for scaffold construction was not implemented with nuclear safety as an overriding priority. The process did not identify and manage risks associated with work in the field nor did it ensure coordination between different work groups and activities. |
