    Harmonised requirements for
    new Nuclear Power Plants

    Common positions and harmonised requirements for the design of new Light Water Reactor
    of Nuclear Power Plants (NPPs), including Small Modular Reactors (SMRs)

Our Vision for future

To address Climate Change threats, a balanced low carbon energy mix, including nuclear, is essential in Europe. To achieve that goal, the nuclear industry needs both to ensure a high level of safety and to maintain its competitiveness.

The EUR Association aims to strongly contribute to safe, competitive, and licensable nuclear New Build projects in Europe through common specifications, harmonised requirements and robust assessments of future Nuclear Power Plant designs, and strong interactions with IAEA, vendors of GEN III reactors, and nuclear regulatory bodies.

Our Products

The Association issues and, from time to time, modifies and updates the ”EUR Document” containing in Volumes 1, 2 and 4, reactor design requirements and technical specifications, and in Volume 3, a number of subsets dedicated to specific designs that have been assessed against the requirement of the EUR Document.

How to get the EUR Document?

The conditions of delivery of the EUR Document (Volumes 1, 2 & 4) and the fees to be paid are defined according to the requesting organisation category. Four categories of requesters are defined.
