Developments in ultrasonic and eddy current testing in the 1970s and 1980s with emphasis on the requirements of the UK nuclear power industry

The 1970s and 1980s marked a significant period of advancement in non-destructive testing (NDT) techniques, particularly ultrasonic testing (UT) and eddy current testing (ET). Some of the strongest drivers for this were the needs of the civil nuclear power industry. This paper explores the historical developments during this era, highlighting the challenges faced by the nuclear industry and the subsequent innovations that emerged. The paper concentrates on technical achievements of the Central Electricity Generating Board (CEGB) and the UK Atomic Energy Authority (UKAEA) in the UK, but also mentions the significant contributions from the improved regulatory framework, validation and certification, and collaborative efforts between industry and research institutions. This paper was written to mark the 60th Annual Conference of the British Institute of Non-Destructive Testing (BINDT) and mentions the role of the Institute???s Past Presidents where appropriate.
