| Title | Licensee-Identified Violation |
| Description | Technical Specification 5.4.1.a, Procedures, requires, in part, that written procedures be established, implemented, and maintained as recommended by Regulatory Guide 1.33, Revision 2, Appendix A, February 1978. Appendix A, Section 3.d, recommends procedures for operation of the emergency core cooling system. Contrary to this requirement, on May 25, 2010, Procedure OTG-ZZ-00006, Plant Cooldown Hot Standby to Cold Shutdown, did not contain sufficient detail for operators to determine if a residual heat removal system aligned to the reactor coolant system with temperatures greater than 240 degrees Fahrenheit could satisfy the requirements of Technical Specification 3.5.3, ECCS Shutdown. This finding was entered in the licensees corrective action program as Callaway Action Request 201005149. This finding is greater than minor because it was associated with the procedural quality attribute of the Mitigating Systems Cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using Manual Chapter 0609.04, Phase 1 Initial Screening and Characterization of Findings, the issue screened as very low safety significance (Green) because it was not a design or qualification deficiency that resulted in a loss of operability or functionality, did not create a loss of system safety function of a single train for greater than the technical specification allowed outage time and did not affect seismic, flooding, or severe weather initiating events. |
