Abstract:
<div>The material in nuclear reactors of the VVER 440 type and their main circulation pipes is exposed to temperatures in the range of 100-300 °C during the operating conditions, but in some nodes can be this range of temperatures exceeded. These temperature conditions are suitable for low-temperature sensitization and the microstructure sensitized in this way may be susceptible to inter-granular corrosion during long-term operation.
