Finding

Title

LICENSEE-IDENTIFIED Violation

Description

South Texas Project, Unit 2, Facility Operating License Condition 2.C.1, requires STPNOC is authorized to operate the facility at reactor core power levels not in excess of 3853 megawatts thermal (100% power) in accordance with the conditions specified herein. Contrary to the above, from August 28 30, 2010, the licensee operated above 100 percent power, as high as 100.16 percent power, as a result of incorrect constants in the new ultrasonic feedwater flow measurement calculator that was installed the morning of August 28, 2010. This resulted in a nonconservative correction to reactor power by 0.16 percent power. Upon recognition, the licensee reduced power below 100 percent and entered the correct constants into the ultrasonic feedwater flow measurement calculator. The licensee captured the issue in Condition Report 10-18932. The violation was processed through the significance determination process and screened as Green, because it did not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment would not function
