| Title | Licensee-Identified Violation |
| Description | Braidwood License Condition 2.E requires, in part, that the licensee shall implement and maintain in effect all provisions of the approved fire protection program as described in the UFSAR, as supplemented and amended. Section 2.3.5.2 of the approved fire protection report describes the Division 22 engineered safety feature (ESF) switchgear room and refers to the description contained in Section 2.3.5.1. Section 2.3.5.1 describes the Division 12 ESF switchgear room and states that the floor is a 5-inch clear cover of structural reinforced concrete with a 3-inch concrete topping over 3-inch fluted steel decking formwork. The floor is supported by structural steel beams protected with a fire resistant covering and carries a 3-hour fire rating. Contrary to the above, on July 28, 2013, a licensee individual performing a routine firewatch activity in the Division 22 ESF switchgear room identified a 25-inch long by 6.5-inch wide section of the poured concrete floor missing and a small nickel-sized hole in the metal floor plate that opened into the 2B EDG room. The un-poured portion of the floor and the hole were previously hidden from view and were recently revealed during installation of an unrelated plant modification. The inspectors screened the issue in accordance with IMC 0612, Appendix B, Issue Screening, and IMC 0609, Appendix F, Fire Protection Significance Determination Process, and determined the finding was of very low safety significance (Green). This issue was entered into the licensees CAP as IR 1540434, GOCAR Un-poured Hole in Floor 426 L-30. |
