NUWARD SMR safety approach and licensing objectives for international deployment
Francis D.,Beils S. 한국원자력학회 2024 Nuclear Engineering and Technology Vol.56 No.3
Drawing on the deep experience and understanding of the principles of nuclear safety, as well as many years of nuclear power plant design and operation, the EDF led NUWARD SMR Project is developing a design for a Small Modular Reactor (SMR) of 340 MWe composed of two 170 MWe independent units, that will supplement the offering of high-output nuclear reactors, especially in response to specific needs such as replacement of fossilfuelled power plants. NUWARD SMR is a mix of proven and innovative design features that will make it more commercially competitive, while integrating safety features that comply with the highest international standards. Following the principles of redundancy and diversity and rigorous application of Defence in Depth (DID), with an international view on nuclear safety licensing, the Project also incorporates new safety approaches into its design development. The NUWARD SMR Project has been in development for a number of years, it entered conceptual design formally in mid-2019 and entered Basic Design in 2023. The objective of the concept design phase was to confirm the project technological choices and to define the first design configuration of the NUWARD SMR product, to document it, in order to launch pre-licensing with the French Safety Authority (ASN) and to define its estimated cost and its subsequent development and construction schedules. As a delivery milestone the Safety Options file (called the Dossier d’Options de Sûret´e (DOS)) has been submitted to ASN in July 2023 for their opinion. An integral part of the NUWARD SMR Project, is not only to deliver a design suitable for France and to satisfy French regulation, but to develop a product suitable and indeed desirable, for the international market, with a first focus in Europe. In order to achieve its objectives and realise its market potential, the NUWARD SMR Project needs to define and realise its safety approach within an international environment and that is the key subject of this paper. The following paper: • Summarises the foundation principles and technological background which underpin the design; • Contextualises the key design features with regard to the international safety regulatory framework with particular emphasis on innovative passive safety aspects; • Illustrates the Project activities in preparation for first licensing in France, and also a wider international view via the ASN led Joint Early Review of the NUWARD SMR design, including Finnish and Czech Republic regulators, recently joined by the Swedish, Polish and Dutch regulators; • Articulates the collaborative approach to design development from involvement with the Project partners (the Commissariat `a l’´energie atomique et aux ´energies alternatives (CEA), Naval Group, TechnicAtome, Framatome and Tractebel) to the establishment of the International NUWARD Advisory Board (INAB), to gain greater international insight and advice; • Concludes with the focus on next steps into detailed design development, standardisation of the design and its simplification to enhance its commercial competitiveness in a context of further harmonisation of the nuclear safety and licensing requirements and aspirations.

Designing organisms with new metabolic properties
Pieper, D.H.,Lehning, A.,Beil, S.,Blasco, R.,Mallavarapu, M.,Hofer, B.,Seeger, M.,Jakobs, B.,Erb, R.,Wittich, R.-M.,Happe, B.,Timmis, K.N. 숙명여자대학교 환경과학연구센터 1996 환경과학논문집 Vol.4 No.-
During the past decades enormous quantities of industrial chemicals have been released into the envionment. Although most of these compounds are readily biodegraded, some-mainly those having novel structural elements or substituents not or rarely found in natrue (xenobiotics)-are only catabolized slowly and thus tend to persist in the environment, Chloroaromatic compounds represent particularly hazardous pollutants. They are and have been used as pesticides, solvents, plasticizers and dielectric fluids, and a number of highly toxic compounds such as chlorinated dioxins have been formed as by-products of industrial processes and during incineration of organic wastes. The existence of many wate storage sites containing toxic chemicals and large scale, though now diminishing, chronic pollution from current industrial practices, necessitate both the termination of production of toxic and persistent industrial chemical, and the more efficient exploitation of remediation technologies, in order to diminish the consequences of existing and ongoing environmental pollution.
