| Title | Inappropriate Use of Elevators by Fire Brigade Members |
| Description | The team identified that AmerGen allowed fire brigade members to use elevators during response to a fire, when the power or control to the elevator could be lost as a result of a fire. This finding was determined to be of very low safety significance (Green) and a NCV of the Three Mile Island Nuclear Station, Unit 1 Operating License condition 2.c.(4), Fire Protection. The team determined that this finding was more than minor because it was associated with the external factors attribute (fire) of the mitigating systems cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e. core damage). Specifically, AmerGen allowed fire brigade members to use elevators during fires which could disable the elevator, potentially trapping fire brigade members and delaying their efforts to extinguish fires in safe shutdown areas. The team assessed this finding in accordance with NRC IMC 0609, Appendix M, Significance Determination Process Using Qualitative Criteria because IMC 0609, Appendix F, Fire Protection Significance Determination Process specifically excludes findings associated with the performance of the fire brigade. Therefore this finding required regional branch chief review in accordance with IMC 0612, Power Reactor Inspection Reports. This finding was screened to very low safety significance (Green) based on IMC 0609 Appendix M, Significance Determination Process Using Qualitative Criteria and the following considerations: the limited exposure time when brigade members would be in the elevator and AmerGens practice that the entire brigade did not enter the elevator all at once. The team determined that this finding had a cross cutting aspect in the area of problem identification and resolution because when the issue of elevator usage by fire brigade members was raised by the NRC residents on November 29, 2007, the issue was not fully evaluated (P.1(c)).
