| Title | Untimely Corrective Actions for Sprinkler Obstructions |
| Description | The inspectors identified a Green NCV of Byron License Condition 2.C.(6) for Unit 1 for failure to take timely corrective actions as described in the Fire Protection Program to address a previously issued NCV regarding sprinkler obstruction by scaffolding in the 1A diesel oil storage tank room. Specifically, the licensee did not fully evaluate the issue before reinstalling a different type of scaffold planks. After the licensee concluded the plank was not acceptable, there was no full extend of condition walkdown until 5 months later and no modification to the scaffold until the inspectors identified the condition in August 2009. The initial violation was originally identified by NRC inspectors in April 2008. This finding is more than minor because it was associated with the external factor attribute of the Initiating Events (IE) cornerstone and affected the cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. The finding is of very low safety significance because it has a low degradation rating as only one out of 11 sprinklers in the room was obstructed and there was another functional head within 10 feet of the combustible concern. This finding has a cross-cutting aspect in the area of Human Performance for Resources (H.2(a)) because the licensee failed to minimize long standing equipment issue. The licensee immediately removed the scaffold obstruction and entered this issue into the CAP as Issue Report (IR) 953448 |
