Title | Licensee-Identified Violation |
Description | GGNS Facility Operating License Condition 2.C(41) states, in part, that the plant shall implement and maintain in effect all provisions of the Fire Protection Program as described in the UFSAR. The fire protection program requires that fire barriers contain the effects of possible fires for the minimum amount of time for which the fire barrier is rated. Contrary to this requirement, plant personnel discovered structural steel fireproofing missing from a steel column that is part of a 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> fire barrier between the Division I and Division II safeguard switchgear rooms. The structural steel requires fireproofing to maintain the fire barrier rating time. The fireproofing was either removed or damaged during maintenance to replace Kaowool with 3-M Interam fire wrap. This issue was documented in the licensees CAP program as CR-GGN-2008-00914. Using the Significance Determination Process, Manual Chapter 0609, Appendix F, the finding was determined to impact the fire confinement category because the fire barrier separated one fire area from another. A moderate degradation rating was assigned because the structural steel would provide some protection from fire propagation. The finding was characterized as having very low safety significance because both areas contained non-degraded automatic gaseous room-flooding fire suppression systems. |
