Preventing a Fukushima disaster in Europe

April 27, 2015, Youris.com

Improved safety management and further collaboration between experts is required to minimise the risk of flooding at coastal nuclear plants in Europe.

In 2005, Europe was exposed to a potential risk of a caused by the flooding of the Loviisa in Finland. Sea levels rose by 1.73 meter above normal levels, due to a storm. As a result, flood defences have been reinforced.

However, latest research reveals that more improvements could still to be made to optimise safety and better protect people from potential future accidents. Floods are likely to occur more frequently than anticipated when nuclear power plants where built, due to climate change.

In Finland several changes in accident management have been introduced, to prevent future nuclear waste leaks. "From our point of view, the priority is to ensure that there is an alternative route to the plant accessible in a flood. By using our pumps and the Loviisa plants' own equipment, water at the site can be reduced," says Peter Johansson, CEO of the Fire and Rescue Services of the local Eastern Uusimaa department attached to the Loviisa power plant.

Further precautions have also been taken. "The latest security investment is the building of four cooling towers that are independent from seawater intake, which are built 10 meters above the sea level to avoid them from being flooded," explains Samuli Savolainen, group leader at the Loviisa plant.

The Fukushima accident, in March 2011, brought renewed scrutiny towards the resistance of plants to natural disasters. The EU stress tests required after the meltdown in Japan, led to the introduction of a precise Severe Accident Management plan, according to Thomas Buddas, vice-CEO of the Loviisa power plant. "We are confident that flooding events can be predicted well in beforehand as we cooperate with the Finnish Meteorological Institute," Buddas tells youris.com. He explains that the top priority is to protect the reactor and the fuel tanks from seawater, and a series of waterproof doors and flood gates have been installed.

Nuclear plants, in particular, are one of the focus infrastructures of interest to a European project called RAIN, due to be completed by the end of 2017. It aims to detect system vulnerability and identify hazards as a result of extreme weather events. As part of the project, Timo Hellenberg, CEO of critical infrastructure protection consultancy Hellenberg International, based in Helsinki, Finland, conducted an analysis of the crisis management process.
Despite all these measures, his findings show that there is still room for improvement. "Foreign specialists should be involved in the emergency training sessions. There is too little inter-agency cooperation. But this is a general European trend," explains Hellenberg. "Emergency trainings should be organised between Finnish agencies and neighbouring countries".

"Finland is in the forefront in nuclear safety, including technological solutions and nuclear safety culture," notes Christer Pursiainen, professor of Societal Safety and Environment at the Department of Engineering and Safety of the Arctic University of Norway in Tromsø. Nevertheless, "The risk of a serious nuclear accident remains always above zero anywhere as a possibility of unexpected phenomena taking place exists."

Look up now many Sieverts it takes to kill you. Let's ask the NRC, the pushers of this technology.

Lethal dose (LD)

"The dose of radiation expected to cause death to 50 percent of an exposed population within 30 days (LD 50/30). Typically, the LD 50/30 is in the range from 400 to 450 rem (4 to 5 sieverts) received over a very short period."

An inconvenient truth is that nuclear power has caused relatively low environmental impact per gigawatt generated even when if it (inclusive Fukushima) is unbiasedly (englobing all aspects) compared with renewables.

-with self-diagnosed 'radiation sickness';

"I didn't know other people were having nosebleed that time. Maybe my allergy saved me in unexpected way such as having to wear a mask all the time.

"The next symptom was the heart pain. I thought it was simply a muscle pain from working out too much. However it started lasting longer than ever, and it became the pain like having pencil sticking my heart ...

"Then I started having persistent diarrhea, coughing and slight fever from August.

I seriously think I would have died if I stayed there. Yes, I found a thyroid nodule in July of 2011 too."

-No, hes no scientist. But at least he knew the difference between dust and debris, and only translated it wrong.

You and your crack team of expert retards however dont, and so had to concoct a nuke explosion to explain it.

Sorry to see otto has not grownup. Too bad.

Fukushima Diary is a news aggegator, who picks up whatever he can get in Japanese, and translates it. He is not the reporter. If you look, the sources are traditional sources plus scientific ones. otto picks out a few sentences from dialogue in the stories, and tries to make it look unimportant.

He uses bully words and phrases like "You and your crack team of expert retards however dont, and so had to concoct a nuke explosion to explain it.", but all bullies are cowards, and we do not know his real name, because he HIDES.

I suggest the rest of you read it for yourselves, and dump otto.

Uh no this is a reasonable conclusion based on objective analysis of months of thoughtless posts full of outrageous pseudoscience that you made up yourself.

I already explained how you and your 'nuclear scientist' experts totally misconstrued the 'vessel parts' vs dust article. How did I do this? I actually read the article, searched the internet, and found it reported independently elsewhere.

But despite the evidence you continue to argue that a Pu prompt criticality was necessary to explain how these 'vessel parts' could get thrown 130km when it was only just the wind. The WIND george.

Im sorry but only the mentally challenged or a sick old man would do this.

George thinks that people who wont let him have his way are bullies. Whos mind is back in kindergarten eh?

They got a reading of 48 Sieverts in one of the buildings. 50% of people die if thy get four to five Sieverts. Who wants to go in and SAVE us?

I think we will have to get those with as little knowledge about nukes as possible, . . wiki warriors, who read stuff from the NRC.

Those of us who have worked with this technology and have been in nuclear powerplants but whose livelihoods are not tied to it know better.

One way to prevent another one is to close all the loser BWR's here. They are real turkeys.

Those of you not familiar with the evolution of the GE BWR can get it from GE itself. Pay special attention to the part where they inform us all the modifications have been for safety, so it will not KILL US!!

Earth's natural radiation is around 3 millisievert per year.
http://en.wikiped...adiation

Thus (48/0.003=16000) with few wind farms, with their related mined materials, installations, and so on, is to expose humans to much more radioactive substances than Fukushima.

Why would you compare natural background with the interior of a Fukushima unit? It makes no sense whatever.

And if you want radiation, go stand downwind of a coal powerplant.

Willie, you apparently do not understand the nature of radioactivity. Look up Hanford, where babies are being born with partial brains. Look at WIPP, which cannot even store radioactive gloves.

Are YOU going to take the waste? If not, tell me how you are going to do what all the scientists have not found a way to do - store the high-level waste. Do you know it is exothermic?

For a brilliant mind, there is always a way.
But unfortunately mediocre fearmongers scientists are majority and love discussing problem and proposing pyrotechnical solutions; they don't want to understand the problem, nor really solve the problem, nor let skilled technical people to find out and execute a well-thought solution; let the whole world only with environmentally hypocrite solutions, large areas with panels and towers.

The Loviisa nuclear plant is more in risk of running out of seawater than being buried under, because the Scandinavian region, Finland and Sweden in particular, are subject to post-glacial rebound which means the ground is still rising after the last ice age. The whole of northern Europe and the British isles are slowly rising up from the sea, and the rebound effect reaches all the way down to northern Italy.

In a hundred years, the water level at Loviisa will drop by about a meter and leave the powerplant stranded inland without access to cooling water as the Baltic Sea recedes and may eventually become an huge lake.

There just isn't any credible risk of a fukushima type disaster in Europe.
