REGDOC-2.6.3 - Aging Management

REGDOC-2.6.3, Aging Management, sets out the requirements of the CNSC for managing the
aging of structures, systems and components (SSCs) of a power reactor facility. Guidance is also
provided as to how these requirements may be met.
Managing the aging of a reactor facility means to ensure the availability of required safety
functions throughout the facility’s service life, with consideration given to changes that occur
over time and with use. This requires addressing both physical aging and obsolescence of SSCs
where this can, directly or indirectly, have an adverse effect on the safe operation of the reactor
facility.
This document is intended for use by licensees and applicants in establishing, implementing and
improving aging management (AM) programs and plans for reactor facilities.
