I think Aliens found bigger planets than ours that have water. Why would they bother with Earth being low tech and have to fight 7 Billion people just for the planet? Plus I'm pretty sure they know we have planet destroying weapons right now seeing how America is killing everything on the planet through pollution and radiation.
TOKYO —
Kyushu Electric Power Co will restart a nuclear reactor in southwestern Japan on Oct 15, making it the second to return to operation after the government introduced stricter safety regulations following the 2011 triple reactor meltdowns at a power plant in Fukushima.
Kyushu Electric reported its plan to reactivate the No. 2 reactor at its Sendai complex to the Nuclear Regulation Authority on Friday.
I would not want to buy a tractor used in cleaning up Chernobyl or Fukushima. Do you have reason to think that vehicles used in the cleanup are being shipped? Anywhere?
I did see a doco once about Chernobyl's clean up and how even the vehicles and equipment used were abandoned or something, but never ever used again by anyone.
For a while fishing in the vicinity was banned but since testing shows nothing much to worry about, why ban it? Public opinion seems to do a pretty good job, justified or not.
So in the aftermath of Fukushima, we did not see a single trade ban on any exports out of Japan.
The China syndrome (loss-of-coolant accident) is a fictional nuclear reactor operations accident characterized by the severe meltdown of the core components of the reactor, which then burn through the containment vessel and the housing building, then notionally through the crust and body of the Earth until reaching the other side, which in the United States is jokingly referred to as being China.[18][19]
In reality under a complete loss of coolant scenario the fast erosion phase of the concrete basement lasts for about an hour and progresses into about one meter depth, then slows to several centimeters per hour, and stops completely when the corium melt cools below the decomposition temperature of concrete (about 1100 °C). Complete melt-through can occur in several days even through several meters of concrete; the corium then penetrates several meters into the underlying soil, spreads around, cools and solidifies. [31]

However in case of Fukushima incident this design also at least partially failed: large amounts of highly radioactive water were produced and nuclear fuel has possibly melted through the base of the pressure vessels.[14]
Cooling will take quite a while, until the natural decay heat of the corium reduces to the point where natural convection and conduction of heat to the containment walls and re-radiation of heat from the containment allows for water spray systems to be shut down and the reactor put into safe storage. The containment can be sealed with release of extremely limited offsite radioactivity and release of pressure within the containment. After a number of years for fission products to decay - probably around a decade - the containment can be reopened for decontamination and demolition.
Take for example cesium-137, with a half-life of 30 years, which makes up the largest fraction of long-lived radionuclides residing in spent nuclear fuel. One gram of radioactive cesium-137 (about half the size of a dime) contains 88 Curies of radioactivity. 104 Curies of radioactive cesium-137, spread evenly over one square mile of land, will make it uninhabitable for more than a century.
Cesium is water-soluble and makes its way into soils and waters as it quickly becomes ubiquitous in a contaminated ecosystem.
Chernobyl, on the other hand, is a different animal than Fukushima because its explosion was much more widespread and more dense than Fukushima, where 80% of initial radiation was blown out to the Pacific Ocean. Hmm.
Yes, the next thread in this forum lists a couple of videos with some good information about effects on the ocean:

Are there any studies out there on the marine wildlife in the surrounding areas to Fuku?

Because ours has fish! And Lobster and crabs and muscles. Did I mention fish?
That is why the dolphins are here after all, or so I've heard.
And that's just it, the aliens were here before shutting down our nuclear missile batteries (silos), to me it says they don't want us nuking ourselves. Now imagine having to travel back home 7 billion miles empty handed. I hope it's a tax write-off.
