Finding

Title

Licensee-Identified Violation

Description

Technical specification 3.17.A, Control Room Heating, Ventilating, and Air Conditioning (HVAC) System , requires that The control room HVAC system shall be operable during all modes of operation. With one control room HVAC system determined inoperable, technical specification 3.17.B requires Exelon to verify once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> the partial recirculation mode of operation for the operable system, or place the operable system in the partial recirculation mode. On October 29, 2012, the B control room HVAC system experienced flow oscillations, was taken out of service and A control room HVAC system was placed in service. On November 1, 2012, Exelon operators initially declared the B control room HVAC inoperable due to the observed flow oscillations; however, Exelon operators, in error, subsequently determined that the B control room HVAC was not required to be operable in the cold shutdown mode of operation. Exelon discovered the error on November 9, 2012 during troubleshooting activities on the B control room HVAC system. Contrary to technical specification 3.17.B, Exelon did not verify or place the A control room HVAC system in the partial recirculation mode daily from October 29, 2012 until November 9, 2012. Exelon entered this issue into the corrective action program as IR 1438918. The inspectors determined that the finding was of very low safety significance (Green) in accordance with NRC IMC 0609, Appendix G, Shutdown Operations Significance Determination Process, Appendix 1, Checklist 7, because the finding did not affect core heat removal guidelines, did not affect inventory control guidelines, did not affect AC power guidelines, did not affect containment control guidelines, did not affect reactivity control guidelines and did not require a quantitative assessment.
