The inspector identified a Green finding aThe inspector identified a Green finding associated with the failure to control or remove material adjacent to the Unit 1 main power transformers, station auxiliary transformers and unit auxiliary transformers. Plant personnel failed to identify these discrepant conditions during the performance of a plant surveillance procedure with the purpose of identifying and removing potential missile hazards from areas where they could damage important plant electrical equipment during adverse weather conditions. The licensee entered this issue into their correction action program. Proposed corrective actions included relocating storage to an appropriate less vulnerable location and reemphasizing good practices related to housekeeping. The finding is greater than minor because the finding could be reasonably viewed as a precursor to a significant event, such as a loss of Technical Specification (TS) required power supplies or a loss of off-site power caused by missile damage to the auxiliary power system. The inspectors determined that because the finding did not contribute to the likelihood of a primary or secondary system loss of coolant accident initiator; the finding did not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions would not be available; and the finding did not increase the likelihood of a fire or internal or external flooding, it was of very low safety significance. The cause of the finding is related to the work practices attribute of the cross-cutting element of Human Performance (H.4(c))ting element of Human Performance (H.4(c))  +
