Observations on implementation of the BAM holistic reliability model

  • Achieving reliability in NDE for nuclear power plants is a complex challenge. As engineers we tend to focus on the equipment and the written procedures; they are easy for us to understand, measure and control. This focus addresses only one of the four aspects of the BAM holistic model, namely, Intrinsic Capability. Another of the model's modules, Application Parameters, also is engineering-oriented as examiners work to ensure that the equipment and procedure can be applied correctly in the actual examination environment as it is found in the field, though in addition to engineering it requires organizational foresight and commitment to understand and prepare for that specific environment well in advance. The Human Factors reliability module is harder for us to think about. The procedure developers think, "Of course all the examiners in the field will understand all aspects of my procedure and execute them correctly."

The Human Factors reliability module is harder for us to think about. The procedure developers think, "Of course all the examiners in the field will understand all aspects of my procedure and execute them correctly." Most of our bad experiences with reliability occur when this happy thought turns out to be untrue. And finally, perhaps the hardest reliability module to affect is Organizational Context. Getting all of the stakeholders -- the plant owner, the NDE company, the examiners, the regulators, the qualification body, the equipment suppliers -- to think about reliability in the same way, years in advance of the examination, to think about reliability at every step in the long process leading to the day of the examination itself, is a heavy lift indeed.zeige mehrzeige weniger
