Decommissioning of the Fukushima No. 1 nuclear power plant ¥8 trillion and many, many ,decades

Long way ahead for decommissioning of nuclear power plant in Fukushima, Japan News.7 Mar 17 “……While the critical situation has subsided, the task of removing melted nuclear fuel from the reactors awaits. Reflecting on the task ahead, TEPCO considers this stage of the decommissioning work “the bottom point of a trek up a mountain.”

Above all else, grasping the situation inside the reactors is essential. To what extent have the reactors been damaged? And does the melted nuclear fuel remain as large chunks or is it scattered around?

The investigation has struck a snag. Extremely high levels of radiation have been monitored inside the reactor buildings, making it difficult to get close. Even though a robot was put to the task of surveying a reactor, obstacles prevented further probing.

Better remote control needed

Inside the No. 2 reactor, the degree of damage was at least partially established earlier this year. On the floor under the pressure vessel of the reactor, a large hole was discovered. It is believed to have been created when nuclear fuel fell down.

Inside reactors Nos. 1 and 3, which are seriously damaged, even probing with a robot is proving difficult.

The government and TEPCO plan to start the extraction of nuclear fuel in 2021. Although they plan to decide on the method of extraction as early as September, relevant data is undeniably lacking.

Further advances of remote control and other technologies are needed.

The issue of radioactive contaminated water, chiefly from groundwater flowing into the reactor buildings, has yet to be fundamentally solved……..The problem is what to do with the vast volume of water that has been kept in storage tanks inside the plant’s premises…….

According to a provisional calculation, the decommissioning of the Fukushima No. 1 nuclear power plant will require about ¥8 trillion. This is a heavy undertaking which needs to be borne by the whole country. It is vital for the government to take the lead to mobilize knowledge and technology, both at home and abroad http://the-japan-news.com/news/article/0003562229

Press freedom: Criminalizing journalistic activity NYT,

The Context

Prosecutors recently expanded a criminal case against Julian Assange to include accusations that he violated the Espionage Act by soliciting, obtaining, and publishing classified documents leaked in 2010 by Chelsea Manning, which could establish a precedent that such common journalistic activities (a separate question from whether Assange counts as a “journalist”) can be treated as a crime in America.

The Question

Are these charges constitutional? Would your administration continue the Espionage Act part of the case against Assange?……..

Elizabeth Warren, Senator from Massachusetts,

Whatever one’s opinions of Julian Assange, these charges under the Espionage Act set a precedent that could be used to target journalists. We should not be using this case as a pretext to wage war on the First Amendment and go after the free press who hold the powerful accountable everyday. more https://www.nytimes.com/interactive/2019/us/politics/press-freedoms-executive-power.html
