Abstract For some 25 years, the Central Electricity Generating Board (CEGB) has been using nuclear reactors as the heat source for the safe, reliable, and economic production of electricity. Prior to, and during, this period many challenges have been addressed in many technical disciplines, and tribologists have often been involved in development work. This paper discusses examples of nuclear engineering where the author has had some personal involvement. The subjects will embrace aspects of tribology, including lubrication, friction and wear, and of production, ie safety, reliability and economy. The intention is to discuss basic aspects of reactor tribology and the strategies pursued in addressing questions. Possible lessons for the future will also be considered. As a ‘personal perspective’, the author concentrates on the advanced gas-cooled reactor (AGR).
