| Title | Grouting in Fire Penetrations Does Not Meet Requirements |
| Event Description | Conditions were identified in which grouting in some fire penetrations through hollow block walls on Units 1 and 2 do not comply with design drawings. While some grouting is present in the penetration, the determination has been made that the qualification of the amount and configuration of the grouting present does not meet Appendix R requirements. Further evaluation by Engineering concluded that this condition could compromise both safe shutdown paths on each unit in the event of a postulated fire. Given this information, the determination was made that this condition meets the reporting criteria of 10CFR50.72(b)(3)(ii)(B).
Compensatory measures were established in accordance with the plant's Fire Hazard Analysis (FHA) to compensate for this condition to ensure that safe shutdown paths are preserved until the conditions can be corrected. The licensee has notified the NRC Resident Inspector. |
