| Title | Licensee-Identified Violation |
| Description | 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, requires, in part, that activities affecting quality shall be accomplished in accordance with documented instructions, procedures or drawings. Contrary to the above, on October 12, 2009, the Unit 2 pressurizer temperature limit, as described in the Braidwood Technical Requirements Manual, Section 3.4.c, was exceeded. Specifically, the heatup limit of less than or equal to 200oF in any one hour was exceeded during filling of the Unit 2 pressurizer. This was documented in the licensees CAP as IR 977969. This finding is of very low safety significance because the licensee demonstrated through analysis that the transient was bounded by existing analyses for pressurizer structural integrity limits and there were no unacceptable flaws in the pressurize lower head and surge nozzle |
