| Title | Licensee-Identified Violation |
| Description | Technical Specification 3.9.13 requires that with one containment radiation monitor out of service during core alterations, core alterations may continue as long as the containment ventilation isolation valves be maintained shut and within one hour, operate the control room ventilation system in the recirculation mode. Contrary to the above, on April 1, 2009, and on prior occasions, core alterations continued with one channel of control room isolation actuation out of service and without the control room ventilation in the recirculation mode. The non-compliance was identified during review of plant conditions while performing engineered safeguards integrated testing with the plant in Mode 6 refueling. The redundant radiation monitoring and actuation channel remained available and had an event occurred, operators would have been able to use standby Self-contained breathing apparatus (SCBA) assuring the safety function. The issue was screened to be of very low safety significance (Green). When identified, the licensee placed the control room in recirculation and isolated the ventilation valves. The issue was documented in condition report 2009-9899 and additional corrective actions were specified. Because the licensee identified the issue and documented it into their corrective action program, and because the finding is of very low safety significance, this violation is being treated as a licensee identified NCV consistent with Section VI.A of the NRC Enforcement Policy |
