| Title | Licensee-Identified Violation |
| Description | Sequoyah Fire Protection License Condition 2.C.(16) for Unit 1 requires that TVA implement and maintain in effect all provisions of the approved fire protection program referenced in the Sequoyah Nuclear Plants Final Safety Analysis Report (FSAR) as described in the Fire Protection Report (FPR). Part III of the FPR states that SQN must comply with 10 CFR 50 Appendix R, Section III.G.Section III.G.2 requires that where cables or equipment of redundant trains of systems necessary to achieve and maintain hot shutdown conditions are located within the same fire area means of ensuring that one of the redundant trains is free of fire damage shall be provided. Contrary to the above, on January 28, 2009, the licensee identified that cables associated with the Unit 1 6900-volt power supply in fire areas FAA 1 and 29 would not be free of fire damage to support safe shutdown (see Section 40A3). This violation is of very low safety significance (Green). This issue was determined to be of very low safety significance based on the results of the IMC 0609, Appendix F, Fire Protection Significance Determination Process, Phase II Quantitative Screening Approach. This violation was documented in the licensees CAP as PER 162189. |
