Assessment and Management of Ageing of Major Nuclear Power Plant Components Important to Safety

Identifies significant ageing mechanisms and degradation locations, and documents current practices for the assessment and management of the ageing of boiling water reactor pressure vessel internals. The report emphasizes safety aspects and provides information on current inspections.

---

The objective of this report is to identify significant ageing mechanisms and degradation locations, as well as to document current practices for the assessment and management of the ageing of boiling water reactor (BWR) pressure vessel internals (RPVIs). The report emphasizes safety aspects and also provides information on current inspections as well as on monitoring and mitigation practices for managing ageing of BWR RPVIs.
