WENRA Statement on Implementation of its 2014 Safety Reference Levels for Existing Reactors

10 September 2018To achieve its aim of improving nuclear safety in Europe, one of the objectives of WENRA, as stated in its terms of reference, is to develop a harmonized approach to nuclear safety and regulation. For this purpose, WENRA has been developing Safety Reference Levels (SRLs) for existing reactors for more than a decade. The emphasis of the SRLs has been on nuclear safety, primarily focussing on safety of the reactor core and spent fuel, but they also include issues like safety policy, management systems and emergency preparedness.

RHWG Report on Regulatory Aspects of Passive Systems

11 June 2018New nuclear power plant designs propose to rely more heavily on passive systems to fulfill several safety functions. This design choice is usually driven as the passive systems relies less on human actions and support systems than active systems. Safety expectations for passive and active systems are similar and only the approaches to implement them may differ considering that passive systems operate differently. More

WENRA Recommendation in connection with macro-segregation anomalies found in French reactors

30 May 2018In late 2014, mechanical tests performed in France on a Reactor Pressure Vessel closure head representative of that of the Flamanville EPR revealed the presence of a high carbon concentration in the central top part, leading to lower than expected fracture toughness values. More
