The demanding environments of an operating nuclear reactor may impact the ability of a broad range of materials to perform their intended function over extended service periods. Identifying materials and components where degradation may occur is an important aspect of safe and secure operation of a nuclear power plant.
“The average operating time of a CANDU power plant is 30 years,” “However, many nuclear power plants would be able to operate safely beyond their initial design life”.
To achieve this, each utility has to demonstrate that high levels of safety and security will be upheld for the extended service period by applying advanced ageing management techniques. Thus it is essential to understand the mechanisms of Material Degradation and radiation damage to the “system structure and components (SSCs) and possible mitigation approaches.
Canadian Nuclear Power Services Ltd. (CNPS) is primarily established for refurbishment of nuclear power plants, and all aspects of material degradation can be looked into by walkdowns.
This paper elaborates Managing Material Degradation in Nuclear Power Plants.
