| Title | Licensee-Identified Violation |
| Description | \"Technical Specification SR 3.6.1.1 required, in part, that the licensee perform leak rate testing in accordance with the Containment Leakage Rate Testing Program. Technical Specification 5.5.14 required, in part, the licensee to establish a program for leak rate testing of the containment as required by 10 CFR 50.54(o) and 10 CFR 50, Appendix J, Option B. The licensee implemented its Containment Leakage Rate Testing Program using Engineering Head Instruction 5300, D. C. Cook Nuclear Plant Containment Leakage Rate Testing Program Appendix J), Revision 5. Engineering Head Instruction 5300, Step 4.4.5.a required, in part, that as-found LLRTs of containment components shall be performed prior to maintenance, repairs, or inspections that could reduce containment leakage integrity. Contrary to this, on October 29, 2007, the licensee failed to perform the required as-found LLRT on Unit 2 containment isolation valves 2-WCR-942 and 2-WCR-946 prior to performing maintenance that could have had the potential to affect the valves\' leak tightness. The licensee entered this violation into its corrective action program as AR 00821487. This violation was of very low safety significance because Unit 2 was in Mode 5 (Cold Shutdown) with the reactor coolant system filled at the time and containment integrity was not required
