| Title | Licensee-Identified Violation |
| Description | Technical Specification 3.3.2, Engineered Safety Feature Actuation System (ESFAS) Instrumentation, required the ESFAS instrumentation for each function in Table 3.3.2-1 to be operable. Table 3.3.2-1, Function 4.e., Steam Line Isolation, required two (2) channels per steam line and is applicable in Mode 1 and Modes 2 and 3, except when one main steam isolation valve is closed in each steam line. When one channel is inoperable, Condition D is entered which required placing the inoperable channel in trip within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. Contrary to the above between October 31, 2013, and November 6, 2013, 1C steam generator steam flow transmitter (FT- 495) was found to have a trip setpoint above the TS required value of 110.3 percent. Action was not taken to either restore the flow transmitter to operable status or place the channel in trip within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> until operations staff was made aware of the issue on November 5, 2013. Subsequently, FT-495 was recalibrated to within the TS allowable value and placed back in service on November 6, 2013. This issue was entered in the licensees CAP as CR 728740. The finding screened to Green, very low safety significance, in accordance with the NRCs SDP because it did not represent an actual loss of function of a single train for greater than its TS allowed outage time. Redundant instruments were available to actuate the main steam isolation function at the required setpoint. This violation is associated with Unit 1 LERs 05000348/2013-003-00 and -01. |
