| description = The inspectors identified a noncited violation of License Condition 2.C.(7), Fire Protection Program, for the failure of fire protection personnel to implement fire protection plan requirements. Specifically, from June 8-12, 2009, fire protection personnel did not identify that a fire barrier door between the Unit 1 emergency diesel generator Train B room and the Unit 1- 3 Enclosure diesel generator Train B control room was obstructed, preventing the door from performing its design function of closing if a fire occurred, and therefore failed to implement compensatory actions. This issue was entered into the licensee's corrective action program as Palo Verde Action Request 3343933.The finding is more than minor because it was associated with the protection against external factors (fires) attribute of the Mitigating Systems Cornerstone and affects the cornerstone objective of ensuring the reliability of systems that respond to initiating events to prevent undesirable consequences. Using Manual Chapter 0609, Appendix F, Fire Protection Significance Determination Process, the inspectors conducted a Phase I significance determination process screening utilizing Attachment 1 of Appendix F. In accordance with the Phase I screening criteria, this finding was assigned a category of Fire Confinement, and a category of Low Degradation Rating, because the degraded fire barrier door did not affect more than one fire area. Using the qualitative screening criteria of Appendix F, this finding was determined to have very low safety significance because more than one fire area was not affected, and because the other emergency diesel generator would be credited to safely shutdown the plant. This finding has a crosscutting aspect in the area of problem identification and resolution associated with the corrective action program because the licensee did not ensure a low threshold for identifying issues and ensure that conditions adverse to quality were identified completely, accurately, and in a timely manner commensurate with their safety significance | | description = The inspectors identified a noncited violation of License Condition 2.C.(7), Fire Protection Program, for the failure of fire protection personnel to implement fire protection plan requirements.
