Here is an interesting and recent news article giving updates about the Fukushima Nuclear Plant and the so called clean up process as of January of 2018. I tried to post it as it's own news post but parts of the board/forum are currently broken (I get string errors) and as a result, it will not allow me to post it separately.
Here is the news article link of interest:
