As the 25th anniversary of the nuclear disaster at Chernobyl in the Ukraine arrives, its lessons may remain unlearned.

"The 83-year-old man spoke with tears in his eyes. 'It's all over. It is better to just die.' He had just learned his small farm would be sealed off at midnight April 21 inside the government's no-entry zone around the Fukushima No. 1 nuclear power plant."

"As he prepared to visit Chernobyl 25 years after the world's worst nuclear disaster, UN Secretary-General Ban Ki-moon outlined a five-step plan to strengthen global nuclear safety."

"The Japanese government is considering whether to impose legal controls on access to an evacuated area around a damaged nuclear power plant, a senior official said on Wednesday."

"The Nuclear Regulatory Commission exists to police, not promote, the domestic nuclear industry -- but diplomatic cables show that it is sometimes used as a sales tool to help push American technology to foreign governments."

"Every year, Volodymyr Palkin spends at least two months in a Kiev hospital. He was one of hundreds of thousands of rescue workers sent to fight the disaster at the Chernobyl nuclear plant and says his health has been permanently ruined by his work."

There is a construction boom in nuclear power reactors in parts of Asia. Some of those reactors are built close to the sea in areas that are likely quite vulnerable to quakes and tsunamis.

"Levels of radioactive materials have risen sharply again in seawater near the troubled Fukushima Daiichi nuclear plant in northern Japan, raising the possibility of new leaks at the complex, the government said Saturday."

"The operator of Japan’s tsunami-damaged nuclear plant said Friday it would pay an initial $12,000 for each household forced to evacuate because of leaking radiation — a handout some of the displaced slammed as too little."

"The Davis Besse incident has resurfaced in the wake of the ongoing nuclear crisis at Japan's Fukushima Daiichi plant. Stories recounting close ties between Japanese nuclear regulators and utilities there have reinvigorated critics who say the NRC has not been an aggressive enough U.S. watchdog."
