| Title | Loss of Safety Function of the Annulus Exhaust Gas Treatment System (Section 4OA3.6) |
| Description | A finding of very low safety significance and a non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, \\\"Procedures,\\\" was self-revealed when a loss of the annulus exhaust gas treatment system (AEGTS) safety function occurred on December 21, 2007. Maintenance procedures failed to include adequate instructions and acceptance criteria related for a hydramotor assembly and this resulted in the inoperability of the \\\'B\\\' AEGTS train while the \\\'A\\\' train was inoperable for charcoal sampling. As part of their immediate corrective actions, licensee personnel restored \\\'A\\\' train to operable status and entered the issue into the corrective action program. The finding was more than minor because it was associated with the Procedure Quality attribute related to maintenance of containment function of the Barrier Integrity cornerstone and affected the cornerstone objective of reasonable assurance that physical design barriers (fuel cladding, reactor coolant system, and containment) protect the public from radionuclide releases caused by accidents or events. Specifically, the finding was determined to have resulted in a degraded condition of secondary containment. The finding was of very low safety significance because the finding only represented a degradation of the radiological barrier function. The primary cause of this finding was related to the cross-cutting area of Human Performance per Inspection Manual Chapter 0305 H.2(c), because the licensee failed to provide complete and accurate procedures related to nuclear safety.
