Uncertain outcome of an expert review regarding lowering the enrichment limit

Ascertain whether a comprehensive expert review of HALEU’s proliferation risks and the associated impacts on reactor technology would conclude with a recommendation to reduce the civilian uranium enrichment limit below 20%.

Background

The authors acknowledge calls for greater clarity from experts with access to classified knowledge about the practical difficulty of constructing HALEU-based nuclear weapons and agree that a new paper or review could be reasonable.

However, they explicitly state that it is uncertain whether such a review would recommend lowering the enrichment limit, highlighting an unresolved question about the policy outcome of an expert assessment.
