... function which interpolated between tabulated values of the thermodynamic and transport properties. The CFD simulations confirmed the risk of condensation hydraulic shock when the blow down is initiated with empty pipes and also demonstrated that a hydraulic shock could be prevented with liquid-filled...

... to measure the thickness at multiple points on a grid pattern drawn on the elbow’s external surface. The thickness measurements provide the data needed for a local metal loss assessment. An AIM program was used to assess the risks, aid in inspection, and develop an assessment for ascertaining...

... of an accidental release of ethylene (ventilation and atmospheric dispersion conditions, gas detection efficiency) and subsequent explosion inside the reactor bay (maximum overpressure, impulsion duration, etc…). The methodology, using a combination of an explosion risk analysis (with help of 3D CFD tool...

... to the consideration whether it is necessary to add a new isolation/mitigation layer in tube furnace in order to control time dependent risks. Taking advantage of the progress of life and probability prediction techniques (such as API581), the time-dependent risk of high pressure tube furnace was studied by taking...

... Nuclear Regulatory Commission (NRC) is considering a risk-informed revision of the design-basis break size requirements for commercial nuclear power plants. In support of this effort, loss-of-coolant accident (LOCA) frequency estimates were developed using an expert elicitation process by consolidating...

... 04 08 2008 Recently, regulatory bodies quite often encourage to adopt risk-based inspection (RBI) and management programs because they can enhance safety simultaneously with deregulation in Korea. RBI is an integrated methodology that factors risk into inspection and maintenance...
