Implications
Communication strategies should include strategic mediaframing to convey messages about nuclear energy. Simply providing more information about energy policies to
raise public awareness of nuclear energy is insufficient.
Effective public deliberation initiatives should beimplemented to include the public in the decision-making ofnuclear energy. Open and transparent deliberation is key to enhance
social trust.
