Fukushima meltdown hastens decline of nuclear power

Is nuclear fission going to make a comeback and plug the gap in our energy needs? Will nuclear fusion ever become energetically viable?

Mystery steam rising over Reactor 3
And now fresh plumes of steam have been seen coming out the structure. These have now been confirmed by Tepco, the owner of the nuclear plant, from 19th December onwards. The company believes the steam is coming from the fifth floor of the building.

However it does not know the cause of the steam. Lethal levels of radiation and the physical damage to the structure have so far made entry and inspection impossible.

Unbelievable. Hilarious.

If you have Google Earth, I'd recommend a virtual drive around Tomoika, which is (was) the small town next to the Fukushima plant, just north of it. Very spooky with all the abandoned homes overrun with weeds. Be sure to check out the shoreline too. Perhaps it will be twinned with Pripyat...

Did Google upload that before or after the disaster? :lol:

TOKYO, Feb 12 (Reuters) - Japan's nuclear regulator has criticised the operator of the stricken Fukushima plant for incorrectly measuring radiation levels in contaminated groundwater at the site.

Almost three years since the reactor meltdowns at the Fukushima Daiichi station, Tokyo Electric Power Co (Tepco) still lacks basic understanding of measuring and handling radiation, Nuclear Regulation Authority (NRA) Chairman Shunichi Tanaka said on Wednesday. The utility has been widely criticised for an inept response to the March 2011 disaster.

Tepco said last week that groundwater drawn from a monitoring well last July contained a record 5 million becquerels per litre of dangerous radioactive strontium-90 - more than five times the total beta radiation reading of 900,000 becquerels per litre recorded in the well, which is around 25 metres from the ocean.

Tepco said there was a calibration mistake with one machine measuring strontium levels of well water at the plant, and it had also found an error with devices that decipher all-beta radiation.

"Something like this cannot happen ... This (data) is what becomes the basis of various decisions, so they must do their utmost to avoid mistakes in measuring radiation," Tanaka told reporters, though he added the mistake did not pose a serious safety risk at the plant.

The legal limit for releasing strontium 90, which has a half life of around 29 years, into the sea is 30 becquerels per litre.

From that article
The Vancouver Aquarium... records show the pH level in Vancouver’s harbour steadily declining, from 8.1 (1954-74) to a low of 7.3 by 2001.
pH 8.1 to 7.3. That is vastly greater than the ocean average drop of .1 that is often quoted. There is something very fishy about those figures. If they are true then there is little wonder the baby oysters are dying, but one would need to find why the pH has dropped so much.

Here's information from the EU at http://www.epoca-project.eu/index.php/w ... n/faq.html
Scientists estimate that surface ocean pH has fallen by about 0.1 pH unit from preindustrial times to today. Because pH is a measure of hydrogen ion concentration and the pH scale is logarithmic — for every drop of 1 pH unit, hydrogen ion levels increase by a factor of 10 — a 0.1-unit pH drop is equivalent to about a 26% increase in the ocean hydrogen ion concentration. If we continue on the expected trajectory for fossil-fuel use and rising atmospheric CO2, pH is likely to drop by 0.3-0.4 units by the end of the 21st century and increase ocean hydrogen ion concentration (or acidity) by 100-150% above what it was in preindustrial times. — Scott Doney, Senior Scientist, Woods Hole Oceanographic Institution, USA

For reference, a drop of one in pH value is equal to becoming ten times more acidic.

Neutral water has a pH of about seven. That means one free hydrogen ion for every ten million water molecules. (Ten to the power seven).

Oops. I should read before posting . :oops:

It came from Fukushima, but how the heck it got so far up the Fraser River Valley in British Columbia has scientists mystified.

A bit of cesium-134 — a telltale kind of radiation particle expected from Japan’s 2011 Fukushima nuclear disaster — has been detected in a soil sample taken from the beach at Kilby Provincial Park, said Krzysztof Starosta, an associate professor of chemistry at Simon Fraser University.

Aren't there nuclear things nearby that might have had leaks in the past and, Silkwood-style, tried to keep quiet about it?

Meanwhile, the UN weighs in, saying there've been complaints from the Neighbours:

http://www.belfasttelegraph.co.uk/news/ ... 10516.html
A special UN environmental committee has written to the Government warning that it failed to notify countries which could potentially be affected by fallout or pollution from Hinkley, regardless of how unlikely an accident is.

"The committee found that there was a profound suspicion of non-compliance," the UN states.

Vesna Kolar Planinsic, chair of the implementation committee on the Convention on Environmental Impact Assessment in a Transboundary Context, said UK representatives will be called before a hearing in December to explain their actions.

Unemployed? Head over to Japan.*
Meanwhile, according to Tepco's blueprint, dismantling the Fukushima Daiichi plant will require at least 12,000 workers just through 2015. But the company and its subcontractors are already short of workers. As things stand now, there are just over 8,000 registered workers. According to government data, there are 25 percent more openings for jobs at Fukushima plant than applicants. Tomohiko Suzuki says these gaps are often filled by the homeless and the desperately unemployed – people who have nothing to lose, including those with mental disabilities.
