PLIM
To facilitate decisions concerning when
and how to repair, replace or modify
SSCs in an economically optimized
way, while assuring that a high level of
safety is maintained.
To assure a safe and reliable NPP
operation, provide a forum for
information exchange, provide key
elements and good practices related to
safety aspects of ageing management
and long term operation.

(International
Forum for
Reactor Aging
Management)
To facilitate the appropriate exchange
of information among parties and
organizations around the world that
are presently, or are planning to,
address issues on nuclear power plant
(NPP) materials ageing management.
Three objectives support this purpose:
(i) cooperating to achieve common
objectives; (ii) sharing information/data;
and (iii) entering into joint research/
demonstration projects.
