For compensation, window 9
Look carefully at the nuclear meltdown tragedy in Japan. The power company (TEPCO) has insufficient resources to clean-up & compensate. The public is forced to pay, although claw-back of past TEPCO dividends would help.
Nuclear disaster is hugely expensive. Worst-case cost figures are hidden by the industry. Proper long-term nuclear waste disposal must be foolproof (so sorry - it isn't). Failure means huge regions may not survive or reproduce.
The nuclear industry should be off-limits to flim-flam marketers, due to hidden horrible threats to health & property. Your local power company assures you all is safe. Sure.
