Energy Glance
According to estimates, Israel has sent back at least dozens of kilograms, probably more, of 93-percent enriched uranium.
The operation took place after Israel's Nuclear Energy Commission and the US Department of Energy signed an agreement for the return of the nuclear waste over a year and a half ago.
Following the agreement, an American ship collected nuclear waste from both Israel and Turkey.

Texas becomes first to require fracking disclosure
Governor Rick Perry has signed a bill requiring gas drillers to publically disclosed the chemicals used in hydraulic facturing, or fracking. That's when water and chemicals are injected into the ground to crack the shale and extract the natural gas.
Ed Ireland with the Barnett Shale Energy Education Council says the industry supports the bill.
Ireland: Once people can go to the database and see exactly what chemicals are used and in what quantity that it will help clear up the debate.
The natural gas industry says fracking is safe and does not contaminate groundwater.
U.S. military's need for biofuels could build new market
Biofuels have buzz in the military because the Air Force and the Navy are taking a lead role in creating a U.S. market for them. They've spent the past few years testing and certifying aircraft to run on them. Now they need hundreds of millions of gallons of biofuels to meet the goals they've set for using alternative energy by the end of this decade.
The challenge for the new industry is to find money to ramp up from nearly zero today. The Department of Defense has called for biofuels that don't displace food, don't use up fresh water, yield less greenhouse-gas pollution than conventional fuels and cost the same. About a dozen companies that want to make this jet fuel for the global market have exhibits for the first time this year at the Paris Air Show, which began Monday.
Fukushima USA? Dangerous radioactive leaks and cracked foundations go unpunished at American nuclear power plants
Safety has taken a back seat to cost-cutting at most of the nation's nuclear power plants, sparking fears that America could be facing its own Fukushima disaster.
An investigation by the Associated Press has revealed federal regulators are repeatedly weakening - or simply failing to impose - strict rules.
Officials at the U.S. Nuclear Regulatory Commission have frequently decided that original regulations were too strict, arguing that safety margins could be eased without peril.
US nuke regulators weaken safety rules
Federal regulators have been working closely with the nuclear power industry to keep the nation's aging reactors operating within safety standards by repeatedly weakening those standards, or simply failing to enforce them, an investigation by The Associated Press has found.
Time after time, officials at the U.S. Nuclear Regulatory Commission have decided that original regulations were too strict, arguing that safety margins could be eased without peril, according to records and interviews.
Tiny lizard could block Texas oil, gas exploration
Deep in the West Texas sand dunes is something that some say could threaten the state's oil and gas production: A tiny lizard. But it's not just any lizard: It's a dunes sagebrush lizard, also known as the sand dune lizard.
This little brown reptile is a concern for state officials, who hope that federal officials don't designate it an endangered species. That, they say, could disrupt oil and gas exploration in the heart of Texas' oil country, leading to higher gas prices and shrinking dollars for schools.
Are We on the Brink of Burying Nuke Power Forever?
This may be the moment history has turned definitively against atomic energy.
But what truly sets this moment apart is not just the radioactive nightmare. There have been others. There will certainly be more.
What's unique about now is the Solartopian flip side. It is the irrepressible fact that we have finally reached the green-powered tipping point.
