The development of a new paradigm necessarily involves both compromises on current positions and, where appropriate, the introduction of new tools to facilitate this development. The objective – extremely ambitious – is to build a universally accepted paradigm for the safety / security of nuclear installations, that is to say a “model of thought” which organises and directs the analysis. Concerning the safety objectives, it is agreed that the harmonisation can be organized through the extension of the safety demonstration (and the strengthening of its robustness) and the reinforcement of the defence in depth (DiD).ģ What are the key conditions to achieve the expected New Paradigm? The important specification to harmonise the safety / security approach is recalled. The need for a really technology neutral approach is pointed out to go further compared with the currently available set of requirements. The notion of Risk is discussed through the use of the so-called “Farmer curve” and the “Risk space”.

Theis Perspectives report addresses examples which deserve discussion in order to identify the actions needed to achieve a full consensus about their content. The education is also an essential mean to help the spreading and the achievement of the harmonisation.Ī good level of consensus already exists on the applicable generic terminology, on the Safety Objectives and on the Principles, also generic, on which must lie the definition of requirements applicable to the design and evaluation of nuclear installations however, differences still exist as regards to the interpretation of their content and the ways for their implementation. This is the case for regulators with actions that continue at regional or international scales as well as for the designers, vendors, operators and, generally speaking, all the involved stakeholders. It may be time for a paradigm shift in the regulatory space.” Practical proposals are necessary to characterise this “ Paradigm shift” and to identify how this can be translated into an innovative harmonised approach.Īll the stakeholders involved in nuclear technologies are engaged in an effort to improve the conditions for harmonisation on a planetary scale. To make further progress in this difficult area, radical actions should be engaged as suggested by CNSC President Rumina Velshi at the International Framework for Nuclear Energy Cooperation’s (IFNEC) Global Ministerial Conference: “ … I think the time is now to think boldly and look critically at regulatory frameworks and be open to the need to re-engineer them. Significant progress has been made but the process has not yet been completed and the situation now appears to be stagnating. Interest in harmonising approaches to the design, evaluation and certification of nuclear installations is universally recognised since longtime. Without claiming to indicate miracle solutions to achieve the desired harmonisation, this “Perspectives” report provides innovative proposals which can help paving the way for the definition of programs which realisation could contribute to the advancement of the reflection.įull Report is available here : Nuclear-21 – Perspectives – Regulation Harmonisation – March 2021.
