Reactor in Japan's 2011 disaster area halted just days after restart

Reactor in Japan's 2011 disaster area

The disaster is another reminder that Japan and most other countries need to rethink whether to continue having large-scale centralized entities control electrical power and distribution, or instead find alternatives including assisting individuals and local entities (e.g. public utility districts, found in some parts of the world) to become better able to become more self-reliant when it comes to how electricity is generated and used.

better be safe than sorry...

to restart power generation and transmission on Sunday but decided to postpone it after failing to place the device to adjust the readings of a neutron detector inside the reactor.

Here we go

"...failing to place the device to adjust the readings of a neutron detector"

Sounds like a basic blunder. Yikes.

The Onagawa plant, located closest to the epicenter of the magnitude 9.0 earthquake on March 11, 2011, was struck by tsunami waves around 13 meters high.

This plant was literally hit by a tsunami, yet it is safe to operate?

It sits next to the ocean? How can this plant be safe?

Good news

@sakurasuki

Your comments have no meaning.

If you know better then use this knowledge but I guess you are just someone putting comments without meaning.

Common technical issue, I believe.

Al plants restarting after a long shut down do face small technical issues. It was just the start of the ramp-up period

The Onagawa plant had the full force of the earthquake and the tsunami. The rectors went into shutdown and there were zero problems with the plant. A contrast to the Fukushima plant which suffered a serious nuclear disaster purely because of the lack of the necessary safety features.

Please let them do the safety stuffs, they are being open and honest. Ps, most power stations now are situated on shorelines, the old, not so productive plants adjacent to rivers are being... reverted to rubble. More energy production = more cooling water.

All of the nuclear power plants are on the sea.

The 13-meter tsunami was stopped by the sea wall at Onagawa, and only a small amount flowed over the top, so that was indeed very lucky, and internal damage was minimal.

PS No idea who Sakurasaki is quoting above with, "Here we go".

in the first place, present Japan's nuclear regulation itself what learn nothing from lesson of Fukushima nuclear disaster, permit to restart nuclear plants without even inspecting practicability of evacuation plans is wrong.

"More stringent safety tests" included stress testing, which sounds impressive but which was only a series of simulated computer tests.

Accidents waiting to happen! Shut all clear down now!

Recommendation for those who gave me two minus points above, read the Onagawa NPP report on Wiki, especially the parts concerning effects of the 2011 earthquake and tsunami.

Thank you.

The power companies spent about ¥15 trillion updating the safety of about 20 reactors.

Not many 40 year old cars on the road, and those that are have stringent shakken test every 2 years.

Nuclear power plants - 40 years old - 'upgraded' with a few hundred thousand tons of concrete barriers, and they are good for another twenty years!

Accidents waiting to happen! Shut all clear down now!

Bad news: we’re gonna start cranking them out like sausages.

we’re not able to curb our desire for electricity.

unless you’re willing to start washing your clothes by hand and sending your messages by carrier pigeon

They wouldn't be doing this if fusion can be realistically realized in the foreseeable future
