| Title | Licensee-Identified Violation |
| Description | St. Lucie Unit 1 Technical Specification 3.3.3.8, Accident Monitoring Instrumentation (with Table 3.3-11), requires, in part, that auxiliary feedwater flow instrumentation be operable in modes 1, 2, and 3. Action 7 of Table 3.3-11 requires inoperable auxiliary feedwater flow instrumentation to be returned to an operable condition within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or otherwise shutdown the unit to hot standby within six hours and to hot shutdown in 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. Additionally, St. Lucie Unit 1 Technical Specification 6.8.1(a) states, in part, that the licensee shall establish, implement, and maintain the applicable procedures recommended in Appendix A of Regulatory Guide 1.33, Rev. 2, 1978. Section 9(a) of Appendix A to Regulatory Guide 1.33, Rev. 2, states, in part, that maintenance that can affect the quality of safety-related equipment should be properly preplanned and performed in accordance with written procedures, documented instructions, or drawings appropriate to the circumstances. Contrary to the above requirements, on May 10, 2012, the licensee did not implement adequate maintenance instructions that were appropriate to the circumstances in work order 40160852-01 to ensure that the safety-related square root extractor for auxiliary feedwater instrument FT-09-2A was wired correctly when it was installed in the plant and returned to service. As a result, FT-09-2A was inoperable from May 10, 2012, until discovery and correction of the wiring error on June 5, 2012 (27 days). The licensee entered this issue into their corrective action program as action requests 1773238 and 1828394. The failure to implement adequate work instructions in work order 40160852-01 to ensure that the square root extractor for FT-09-2A was wired correctly was a performance deficiency. The performance deficiency was more than minor because it was associated with the equipment performance attribute of the mitigating systems cornerstone and adversely impacted the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events. The inspectors evaluated significance of the issue using NRC Inspection Manual Chapter 0609.04, Initial Characterization of Findings; and Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process for Findings at Power, Exhibit 2. The inspectors determined the finding was of very low safety significance (Green) because the inoperable flow indication did not result in a loss of auxiliary feedwater heat removal safety function. Because this violation was of very low safety significance and was entered in the licensees corrective action program as action requests 1773238 and 1828394, this violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the NRC Enforcement Policy. |
