SIZEWELL-B VIBRATION MONITORING

In 1993, NNC tendered against international competition for a contract to carry out vibration monitoring of pipework, constructed to ASME st andards, during commissioning of the Sizewell B Nuclear Power Station in Suffolk, England. Some plant features - both novel and established designs - suffered from teething problems which were sorted out at the commissioning stage. In addition to installing and maintaining a majo r vibration monitoring system on the plant, NNC undertook a wide range of other instrumentation, measurement and analysis tasks, helping to provide data and solutions for several deficiencies over a two-year pe riod.
