Highly-experienced in his field, Charles Schneider has specialised in the reliability and theoretical modelling of non-destructive testing (NDT) techniques for 40 years, including 11 years working with UK nuclear generating companies and over 35 years of experience in writing and reviewing technical justifications (TJs) for various NDT procedures.
During his early career, Charles worked mainly on the development and application of mathematical models for ultrasonic testing, including helping to statistically quantify the reliability of the Sizewell B pressurised water reactor Primary Protection System software. In 1996, he was appointed Nuclear Safety Case Engineer, with responsibility for implementing schemes for analysis of component reliability data.
Since joining TWI in 1997, Charles has played a leading role in the independent qualification of various ultrasonic inspections, including the development of NDT guidance for the BS 7910 and R6 procedures, drawing on his project experience in determining flaw sizes for input to engineering critical assessments.
Charles has undertaken statistical and probabilistic analysis across various engineering disciplines at TWI, including the analysis of fatigue test data, and has also used statistical methods to extrapolate corrosion mapping data both in time and for uninspected regions of large plant items.
An area of current interest is the extension of guidance to the probabilistic assessment of structural integrity.
Like all of our Technology Fellows, Charles was selected for the position by the TWI Executive Team in recognition of his knowledge and experience. He has made a significant impact through his technical excellence, expertise and knowledge transfer as well as showing a commitment to developing and coaching colleagues, passing his knowledge on to the next generation of TWI experts.
