On Tuesday, one pool was reportedly so hot that its remaining water was either boiling or close to it. The spent-fuel pools have been a continuing source of problems in the Japan nuclear crisis.

The nuclear crisis in Japan grew more troubling Sunday as efforts to control the Fukushimi Daiichi nuclear power facility continued to hit unexpected roadblocks. But Energy Secretary Steven Chu says Americans "are in no danger" from radiation.

Chernobyl and Three Mile Island did not stop nuclear power growth. Will the Japan nuclear crisis at Fukushima delay or end the 'nuclear renaissance'?

Fourteen safety-related events at nuclear power plants required follow-up inspections from the Nuclear Regulatory Commission, the NRC reported in 2010. These "near-miss" events "raised the risk of damage to the reactor core – and thus to the safety of workers and the public," concluded a new report, "The NRC and Nuclear Power Plant Safety in 2010," by the Union of Concerned Scientists. Here are five of these 14 "near miss" examples:

The Nuclear Regulatory Commission failed to resolve known safety problems, leading to 14 'near-misses' in US nuclear power plants in 2009 and 2010, according to a new report from a nuclear watchdog group.

Japan pours tons of water into a reactor building where the water level in a cooling pool for spent fuel rods was dangerously low. The nuclear crisis is now rated as severe as Three Mile Island.

Scientists point to several factors. On Thursday, the Japan nuclear crisis took a hopeful turn as engineers installed a cable to connect the Fukushima I nuclear power plant to the utility grid.

A top nuclear regulatory official testified Wednesday that Japan's nuclear plant might already be too dangerous to allow repairs, even though external power could soon be available to run crucial water pumps.

Workers at Japan's stricken Fukushima nuclear power plant are still days – if not weeks – away from bringing the crisis under control. The reason: nuclear fuel rods remain dangerously hot well after reactors are shut down, and all cooling systems at Fukushima have failed.

Spent-fuel pools are shielded only by the buildings at Japan's Fukushimi I nuclear power plant, and three have now been damaged by explosions. Low-level radiation leaking from the pools could dramatically worsen if the water levels drop low enough for spent rods to burn.
