As in finance, ensuring that the originator of a risk pays the cost seems to be the most sensible approach. If each nuclear-power plant was obliged to insure against the risk that it imposes on society (within and outside the country of its location), it would face the true economic cost of its activities.
在金融方面，最合理的方式莫过于确保风险的始作俑者承担其导致的成本。如果每个核电站都必须为自身可能对社会（包括国内外）所造成的风险投保的话，它就将面对自身行为的真正经济风险。
