Abstract

Nuclear regulations aim to minimize industrial risk, and assure the safety of workers and the public. In order to effective, regulations will often impact industrial processes and sometimes, industry organisation. It is therefore logical that any change in the regulation and its philosophy will have a significant impact on the industry.

This paper will present the evolution of the French regulations over the past 15 years, starting with the Nuclear Regulations which orientates the nuclear technology, toward maximizing safety of workers and public. Utilities and vendors have to comply with these regulations, which may modify the design and manufacturing process, and sometimes, industry organization. Through the case of the updating of French Nuclear order for pressure Equipment on September 3rd, 2018 [1], it will be reminded how the first Order in 2005 has affected current projects, and how nuclear codes has taken in account these new requirements from 2005 to 2015 [3]. It will be explained convergence of AFCEN codes requirements with regulation, and latest updating of ESPN Order in 2015 [3] and 2018 [1]. New approaches with Essential Safety Requirements, specific of European Regulation Pressure Equipment Directive in Europe (2014/68/UE) [7], give objectives to achieve, like risk analysis, Particular Material Appraisal (PMA), technical qualification of Material, among other, and they will be described, when they are applied to nuclear Equipment. Guides and AFCEN Technical Publication (PTAN) will illustrate in detail how the RCC M issued in 2018 [5] has been improved. The communication will conclude with the analysis of the effect of the new French regulation on nuclear reactor’s projects outside France.
