| Title | Inadequate 10 CFR 50.59 Safety Evaluation |
| Description | The inspectors identified a NCV of 10 CFR 50.59, Changes, Tests, and Experiments, for PSEG\'s failure to perform an adequate safety evaluation for an approved design change involving primary containment isolation valves (PCIVs). Specifically, the safety evaluation did not identify the impact of a design change that increased the allowable closing stroke times of several PCIVs, which resulted in more than a minimal increase in the potential radiological consequences of an accident. PSEG\'s corrective actions included blocking procedure changes that incorporated the design change and implementing a new design change to return the PCIV stroke times back to their original design values. Violations of 10 CFR 50.59 potentially impede or impact the regulatory process and are, therefore, dispositioned using the NRC Enforcement Policy. In accordance with the Enforcement Policy, the performance deficiency was more than mi or because it is associated with the design control attribute of the Barrier Integrity cornerstone, and it adversely affected the cornerstone objective of providing reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. The inspectors performed a Phase I screening of the finding using IMC 0609, Attachment 0609.04,Table 4a, Barrier Integrity cornerstone. The issue screened as Green, because there was no actual open pathway in the physical integrity of the primary containment and because the design change, although approved for implementation, was not actually incorporated into station procedures. Therefore, the violation is categorized as Severity Level IV in accordance with Section 6.1.d of the NRC Enforcement Policy. The underlying finding had a cross-cutting aspect in the area of human performance, because the station did not provide proper supervisory and management oversight of work activities, including contractors. Specifically, engineers, supervisors, and managers did not properly oversee contractor engineering products, including performing a rigorous technical review of the products for a design change, that resulted in an inadequate 10 CFR 50.59 safety evaluation. |
