Four months after Japan's devastating earthquake and tsunami, operators at the Fukushima Daiichi nuclear power plant are still grappling with the crisis the disaster unleashed but say they are making slow progress.
Despite periodic setbacks - including a water leak that shut down operations for several hours Sunday - the Tokyo Electric Power Company has managed to set up a decontamination system that filters radioactive material from the water.
Some of the treated water is now being circulated back through the reactors, a key step toward keeping the reactors' melted nuclear cores cool on a permanent basis.FULL STORY
U.S. President Barack Obama and congressional leaders enter the week struggling with negotiations over raising the federal debt ceiling, now with just three weeks left before the country would begin defaulting on its obligations without a deal. Here is a look at this and other stories that CNN plans to follow this week:
Debt negotiations stumbling over proposed tax hikes
Congressional Republicans say they want an agreement to cut federal spending before agreeing to raise the federal debt ceiling, which the Treasury Department says should be done before August 2 to prevent default. But over the weekend, efforts to secure a major deficit-reduction deal took a hit when Speaker John Boehner, R-Ohio, said his party wouldnāt go along with Democratsā insistence that cuts be paired with higher taxes.
Without Republican support, no deal would pass the GOP-controlled House.
Congressional leaders are in talks Sunday evening with President Barack Obama at the White House, hoping to craft a comprehensive deficit reduction deal that appeared to stall earlier in the weekend.
The key players - including House Speaker John Boehner, R-Ohio, and Senate Majority Leader Harry Reid, D-Nevada - met in a White House conference room Sunday evening.
When asked before the start of Sunday's talks if a deal could be reached within 10 days, Obama told reporters, "We need to."FULL STORY
