| Title | Licensee-Identified Violation |
| Description | A licensee-identified violation of Hatch Unit 2 Technical Specification 3.6.1.3 was discovered on September 14, 2013, when the Unit 2 D outboard main steam isolation valve failed to stroke closed during surveillance testing. Technical Specification 3.6.1.3 requires that each primary containment isolation valve, except reactor building-to-suppression chamber vacuum breakers, shall be operable and, when a main steam isolation valve penetration flow path is inoperable, the steam line penetration shall be isolated within eight hours. Contrary to this technical specification, Hatch Unit 2 D outboard main steam isolation valve was determined to be inoperable from March 17, 2013, through September 14, 2013, and the unit was operated with the main steam isolation valve penetration not isolated. This violation screened as Green because the D inboard main steam isolation remained operable and therefore resulted in no loss of isolation function. |
