Specific relationships with community in charge of nuclear reactor safety (utilities, safety authorities, vendors, and research or services companies) will be established in order to define the current needs in terms of guidelines for level 2 PSA development and applications.

A technical group of level 2 PSA experts from project partners will propose guidelines for a limited-scope and a full-scope L2 PSA based on practical experience of each partner and international cooperation (especially SARNET). Elaboration of these guidelines for operating plants will be the main activity of this coordination action. This guideline will be discussed with end-users community and their opinion will be taken into account in the final version. The applicability of such a guideline for future reactors of Generation IV will be also examined.
