The earth’s climate is in crisis. We must achieve sharp declines in greenhouse gas emissions by 2030. Proponents of nuclear power argue we must use “every tool available” to meet this goal, including aging nuclear power plants and a “new generation” of nuclear reactors — such as “advanced” or Small Modular Nuclear Reactors (SMNRs). It is essential, however, that we choose the right tools to address climate disruption — to employ solutions that are sustainable and equitable, protecting health, safety, and our fragile environment. Nuclear power is a dangerous distraction from the need to take immediate and effective action to address the climate crisis.
