| Title | Emergency Diesl Generator Air System May Not Be Appropriately Qualified |
| Description | A finding of very low safety significance (Green) and an associated Non-Cited Violation of 10 CFR 50.59 were identified by the inspectors for the licensees failure to obtain a license amendment when it failed to properly assess a quality assurance typing change to the emergency diesel generator starting air compressors. Violations of10 CFR 50.59 are considered to be violations that potentially impede or impact the regulatory process, and are dispositioned using the traditional enforcement process. The licensee entered this issue into its corrective action program as CR 326432 for evaluation and development of corrective actions, as appropriate. Supplement I of the Enforcement Policy was used to determine the severity of the underlying technical issue evaluated under the SDP. The issue was determined to be more than minor because it was associated with the Mitigating Systems Cornerstone attribute of design control and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). The inspectors evaluated the finding using the SDP and the inspectors screened the issue as very low safety significance (Green) because the quantity of air available to supply air for five start attempts of the diesels and to supply support systems for the emergency diesel generators always exceeded that needed for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of operation, thereby, resulting in the probabilistic risk assessment function for the diesels being met. The inspectors determined this issue had a cross-cutting aspect in the area of Problem Identification and Resolution, trending and assessment, because the licensee failed to perform aggregate assessments that could have identified and prevented this and related issues earlier. |
