| Title | Inadequate Controls of Crane Work Above the Protected Train of Essential Service Water |
| Description | The inspectors identified a noncited violation of 10 CFR 50.65(a)(4), Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants, associated with the licensees failure to adequately assess and manage risk associated with crane work over the essential service water system Train A. On March 31, 2009, the licensee performed work in the vicinity of the protected essential service water system train consisting of jack-hammering of the backfill material and movement of 1800 pound sand bags over the protected train piping. The resident inspectors observed these activities and noted that crane loads were suspended over safe shutdown equipment and questioned if adequate protection was provided for the protected train of essential service water. Interviews with the crane operator determined that the lift was not performed in accordance with the requirements on an engineering judgment memo that limited the lift height to 2 feet. The 2-foot height requirement was exceeded because the engineering analysis was not translated into the work instructions for the crane operator. Subsequent analysis by the licensee determined that the sand bags were lifted to a height of approximately 12 feet above the exposed protected train piping but that a postulated load drop from that height would not impact the protected essential service water train. This finding was determined to be more than minor because it is similar to Example 7.g of Manual Chapter 0612, Appendix E, Examples of Minor Issues, in that key safety functions were significantly degraded without sufficient compensation. Specifically, the licensee failed to implement the prescribed significant compensatory measures associated with crane work in the vicinity of safe shutdown equipment. This finding had a crosscutting aspect in the area of human performance associated with the work controls component because the licensee failed to include appropriate risk insights in planned work activities. The licensee entered this item into their corrective action program as Callaway Action Request 200902726 H.3(a) |
