Link to IAEA Draft Safety Guide: DS528

The IAEA is seeking comments from their member states on revision of existing guide IAEA Safety Standards Series No. SSG-4, Development and Application of Level 2 Probabilistic Safety Assessment for Nuclear Power Plants 2010.

This Safety Requirements has been revised, taking into account the latest developments and relevant practices in the Member States as well as the feedback from the Fukushima Daiichi nuclear accident in 2011. Among the significant changes incorporated into the Safety Requirements publications are those related to severe accidents, and the margins to both withstand extreme external events and avoid cliff edge effects. Those changes have had an impact on safety provision incorporated, in the plant design as well as on the plant operation for all plant states, to cope with severe accidents which are modelled in Level 2 PSA.

Objective

The revised Safety Guide is intended for use by designers, operating organizations, technical support organizations and regulatory bodies in the development, application and independent review of Level 2 PSA. The revised Safety Guide is also intended for use in connection with both the review for authorization (licensing) of the construction and the operation of new NPPs and the safety re-evaluation of existing NPPs during periodic safety reviews and modification
