A group of five non-governmental organisations has called on the US Nuclear Regulatory Commission (NRC) to set up policies which can help speed up the process of reviewing and licensing advanced nuclear reactor technologies.

A letter signed by the Third Way, Clear Path, Action Good, Energy Collective, Clean Air Task Force and Nuclear Innovation Alliance NGOs said that while the NRC had committed earlier this year to establish “transparent, detailed, objective performance metrics” for these technologies, more action may be needed.

The letter said the NRC can “foster a culture of proactiveness and continual improvement” by developing clear expectations for new reactor licensing and performance metrics.
