State legislation: Illinois bill aims to lift state’s remaining nuclear moratorium
A bill that would fully repeal the state’s entire moratorium on new nuclear projects survived a key deadline in the Illinois General Assembly last week.
To stay afloat in the spring legislative session, bills needed to be assigned to committee by March 21, and state Sen. Sue Rezin’s Senate Bill 1527 now sits with the Senate’s Energy and Public Utilities committee for review.

The U.S. nuclear industry is currently in the middle of a historic shift towards the utilization of risk-informed performance-based (RIPB) design and licensing approaches. Moving from a supporting role, RIPB methods are now leading key reactor decision-making. Such methods permit flexibility and encourage consistency between the plant’s risk profile and appropriate design and licensing actions. However, RIPB approaches are not without their difficulties, including the need for detailed probabilistic assessments and addressing a lack of historic precedent in many areas. This panel explores the current transition to RIPB approaches, including efforts that are currently underway, plans for the future, and hurdles to overcome.
