| Title | Failure to Ensure Roll-up Fire Doors Complied with Fire Code |
| Description | The inspectors identified a noncited violation of License Condition 2.G because the licensee failed to ensure that two fire-rated roll-up doors complied with the mounting requirements in National Fire Protection Association (NFPA) 80-1977. Specifically, during original construction, the licensee used bolts with a diameter less than the required 3/8-inch. The licensee entered this finding into their corrective action program for resolution as Smartform SMF-2008-001637. Failure to meet the mounting requirements of NFPA 80-1977 for fire-rated roll-up doors is a performance deficiency. The inspectors determined this deficiency was more than minor because it was similar to the more than minor description in Manual Chapter 0612, Appendix E, Example 3.g. This finding affected the mitigating systems cornerstone. This fire confinement finding was assigned a Moderate A degradation rating because the fire-rated roll-up door had improperly installed fire door hardware. Using NRC Inspection Manual Chapter 0609, Appendix F, Fire Protection Significance Determination Process, Phase 1, Step 1.3.2, Question 5, the exposed fire area contained no potential damage targets closer than 20 feet (i.e., passive barrier) to the exposing fire area that would result in a demand for safe shutdown and the fire barrier would remain functional for at least 20 minutes. Therefore, the degraded fire-rated roll-up doors had very low risk significance (Section 4OA5). |
