Narrative
9/21/2011 - john sterrett a third party contacted field operations of a vapor cloud. A field technician was called out and verified the leak was at a crossover valve. Both lines connected to the crossover were blocked in. The crossover was then blocked in and blown down for repair. The end connection of a small body bleed check valve on the northbound side of a general twin seal crossover valve failed. County sheriff and fire department were called as a courtesy. The small check valve and associated tubing assembly was replaced, and both lines were returned to service within approximately 2 hours of discovery of the leak. The incident did not meet the criteria for an nrc telephonic report. 7/19/2012 - nhan truong a kiefner & associates, inc. Lab analysis received on june 22, 2012 (attached) concluded that the 1-inch fitting failed by a fatigue crack that initiated on the internal surface of the threaded portion of the fitting. The crack propagated nearly completely around the circumference of the fitting before it failed. The source of the alternating stress that caused the fatigue was not identified.
