This robot will help clean up the radiation-filled Fukushima power plant
 
Japan is just getting started on tearing down its wrecked Fukushima Dai-Ichi nuclear power plant — a process that's expected to take 30 to 40 years, according to the plant's manager.

WHOI chemist Ken Buesseler held a public lecture at the Aquarium of the Pacific in Long Beach, Calif. on 3/11/15, the fourth anniversary of the earthquake and tsunami that crippled the Fukushima Dai-ichi nuclear power plant and led to the largest unintentional release of radioactivity into the ocean in history. Dr. Buesseler described what is known about the release, some of the sources of natural and manmade radionuclides in the ocean, and what these mean for marine life and for humans.
 
 
 
It's a good thing to know about the things that will happen with all the new mixing of radiation in the waters of the Earth!

Not only the tuna but plankton as well. This stuff is all over the ocean and is responsible for much of the Earths oxygen output.

Nuke Experts: Fukushima plant must be entombed like Chernobyl — Reactors will remain a threat to world “for the rest of time” — “Humanly impossible” to clean up due to shockingly high radiation levels

Here's a story saying it's ok to return and live in the area. Doesn't radiation last for decades, even centuries. The doses won't kill you quick but I bet in 5 to 10 years people will start getting all kinds of diseases. Never mind the current generation...how about the next ones down the line?

Six years later, some workers at Fukushima nuclear plant say they can do without protective gear
 
Since the radiation has dropped sharply at the facility, about 10,000 people per year, including journalists from the United States, Europe and Asian countries, have visited. Last year, high school students dropped by.
 
After the two-hour tour, a dosimeter carried by a reporter showed she was exposed to only 40 microsieverts, less than the amount from a chest X-ray.
 
Although the working environment has certainly improved, the fate of the plant is far from clear.
 
Decommissioning the crippled reactors is expected to take 30 to 40 years. The utility is aiming to begin removing fuel debris from one reactor by the end of 2021, but so far it has failed to even ascertain the condition inside the reactors.
 
A lot of rubble remains in many of the buildings on the seaside, keeping alive fears of a quake-tsunami catastrophe like the one that struck six years ago.
 
A frozen underground wall has seen only limited success in preventing groundwater from flowing into the reactor and turbine buildings, regulators have said, acknowledging that the facility is still a perpetual generator of tainted water.
 
Tepco is also struggling to dispose of tainted waste, such as used protective garments, gloves and socks. It has burned 1,500 tons of such waste while monitoring the radiation in the smoke. It still had 70,000 cu. meters of garbage as of the end of February.
 
“Through legislation, we are prohibited from taking radioactive contaminated garbage outside the facility even after we incinerate it. We have to continue the fight against garbage and ash,” Hirose said.
 
Public confidence in Tepco has been shaky in the wake of the meltdowns, and even now, nearly 80,000 residents are unable to return to their homes near the plant.

Swimming robot probes Fukushima reactor to find melted fuel
 
TOKYO - An underwater robot entered a badly damaged reactor at Japan's crippled Fukushima nuclear plant Wednesday, capturing images of the harsh impact of its meltdown, including key structures that were torn and knocked out of place.
 
TEPCO spokesman Takahiro Kimoto praised the work, saying the robot captured views of the underwater damage that had not been previously seen. However, the images contained no obvious sign of the melted nuclear fuel that researchers hope to locate, he said.
 
The robot was left inside the reactor near a structure called the pedestal, and is expected to go deeper inside for a fuller investigation Friday in hopes of finding the melted fuel.
 
"The damage to the structures was caused by the melted fuel or its heat," Kimoto told a late-night news conference held nine hours after the probe ended its exploration earlier in the day.
 
The robot, about the size of a loaf of bread, is equipped with lights, maneuvers with five propellers and collects data with two cameras and a dosimeter. It is controlled remotely by a group of four operators.

The underwater robot has captured images and other data inside Japan's crippled nuclear plant on its first day of work. The robot is on a mission to study damage and find fuel that experts say has melted and mostly fallen to the bottom of a chamber and has been submerged by highly radioactive water.
