Viewpoint: Collaboration - the key to streamlining nuclear regulation

The application and interpretation of the same safety objectives into specific national regulatory requirements and guidance result in significant differences between the same reactor design when deployed in different countries, writes Claude Mayoral. A more harmonised approach to regulation will be needed to enable the widespread deployment of small modular and advanced reactor designs.

UK selects HTGR for advanced reactor demonstration

UK selects HTGR for advanced reactor demonstration

The UK will build a high-temperature gas reactor as the centrepiece of its Advanced Modular Reactor Research, Development & Demonstration Programme, energy minister Greg Hands has confirmed. "I'm pleased to announce that we will focus on HTGRs as the technology choice for the programme moving forward," he told the Nuclear2021 conference organised in London by the Nuclear Industry Association yesterday. His statement served as a confirmation of the technology, which had emerged as the UK government's preference after a round of consultations earlier this year.

Regulator OKs fix to Flamanville EPR nozzle welds

Regulator OKs fix to Flamanville EPR nozzle welds

France's nuclear safety regulator, the Autorité de Sûreté Nucléaire, has approved EDF's proposed solution for rectifying a design anomaly on three nozzles in the main primary system of the Flamanville EPR reactor. EDF's proposal to install a retaining collar around each of the concerned connections is not expected to delay the planned startup of the unit in late-2022.
