Title

Licensee-Identified Violation

Description

TS 3.6.3.2, Containment Atmosphere Dilution System, requires that, if one CAD subsystem is inoperable, then restore the subsystem to operable within 30 days or be in mode 3 within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months . Contrary to the above, from June 17, 2015, to July 31, 2015, a period of 34 days, A CAD subsystem was inoperable without the plant being placed in mode 3 within 30 days and 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months of becoming inoperable. Also, contrary to the above, from August 5, 2015, to November 11, 2015, a period of 99 days, B CAD subsystem was inoperable without the plant being placed in mode 3 within 30 days and 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months of becoming inoperable. FitzPatrick staff entered this issue into their CAP as CR-JAF-2015-05453. In accordance with IMC 0609.04, Initial Characterization of Findings, and Exhibit 2 of IMC 0609, Appendix A, The Significance Determination Process for Findings At-Power, the inspectors determined that this finding was of very low safety significance (Green) because the performance deficiency was not a design or qualification deficiency, did not involve an actual loss of a safety function of a single train for greater than its TS allowed outage time (because operator action could be taken to restore system function if the subject temperature transmitter failed), and did not screen as potentially risk-significant due to a seismic, flooding, or severe weather initiating event.
