| Title | Licensee-Identified Violation |
| Description | A licensee-identified violation of Hatch Unit 2 Technical Specification 3.6.4.3, Standby Gas Treatment System, was discovered by site engineering on December 10, 2012. Technical Specification 3.6.4.3 requires in part that Unit 1 and Unit 2 standby gas treatment subsystems required to support LCO 3.6.4.1, Secondary Containment, shall be OPERABLE in Mode 1. Contrary to this Technical Specification requirement on November 6, 2012, while Unit 2 was operating in Mode 1, the licensee removed the Unit 2 refueling floor hatch which caused the 2B standby gas treatment train flow to exceed 4000 cubic feet per minute. Hatch Unit 2 Surveillance Requirement 3.6.4.1.4 lists the operable flow limit for each standby gas treatment subsystem to be less than or equal to 4000 cubic feet per minute. From November 6, 2012 through November 17, 2012, the 2B standby gas treatment train flow exceeded Surveillance Requirement 3.6.4.1.4 requirements and was therefore inoperable. The licensee entered this issue into their corrective action program as CR 576864. The inspectors screened this violation as Green per IMC 0609, Appendix A, Exhibit 3, question C.1, because this violation represented only a degradation of the radiological barrier function provided for the standby gas treatment system. |
