Under the cooperation programme between ASEAN Centre for Energy (ACE) and Global Affairs Canada–Nuclear and Radiological Programme Administrative Support (NRPAS), ACE released a pre-feasibility study that provides information on the current status and milestones of nuclear energy programmes in the ASEAN Member States (AMS). As NRPAS aims to enhance the AMS’ capacity in promoting civilian nuclear energy programmes, the pre-feasibility is expected to serve as a useful reference to energy policymakers and stakeholders in the region.
