On April 26, 1986, a reactor at the Chernobyl Nuclear Power Plant in the Ukraine exploded, precipitating the worst nuclear disaster in history. Now, on the twenty fifth anniversary of the explosion, it is worth revisiting this horrific episode and to reflect on the lessons we still have not learned.

In Japan, fears about nuclear fallout have only been getting worse as disaster cleanup crews struggle with radioactive water leaking out of the Fukushima plant.

Even as Fukushima threatens to unleash the greatest nuclear catastrophe since Chernobyl, the president champions nuclear power in the United States.

The 1979 partial meltdown prompted more regulations and greater enforcement. Then in the 1990s, a Republican Congress took aim.

Joining Charlie Rose, Schell explains that nuclear power has no place in a world so vulnerable to widespread disaster.

According to Christian Parenti, the US Nuclear Regulatory Commission's "culture" of bowing to industry demands prevents it from keeping plants truly safe.

The problem with mankind wielding nuclear power isn’t about backup generators or safety rules—it’s our essential human fallibility.

The message out of Fukushima is clear: our own fleet of leaky old nuclear plants should be decommissioned now.

America's nuclear power plants are poorly managed and regulated, and it's time they were taken out of commission.
