The SMR-300 plant is configured to mitigate the contributing causes that are known to induce aging through:
- Minimized cumulative radiation (fluence) on load bearing parts and welds.
- Reduced generation of crud with its high corrosive species.
- Minimization of mechanical aging effects such as flow induced vibration, metal fatigue and the like.
- Maintaining material temperatures well below the limit at which adverse effects such as stress corrosion cracking may occur.
- Instrumentation and control systems are designed with a strategy to manage obsolescence over plant life.
- All components are designed for either full-service life or are readily accessible for replacement without major plant modifications.
