The News That Matters about the Nuclear Industry Fukushima Chernobyl Mayak Three Mile Island Atomic Testing Radiation Isotope

Finland, stuck with increasingly costly Olkiluouti nuclear nightmare, plans and even worse expense, with small nucler reactors!

Taz 26th Oct 2020, The European pressurized water reactor Olkiluoto 3 has long since developed into a Finnish BER – at least twelve years too late, three times as expensive as planned. And it’s far from being online. The same goes for the
new Hanhikivi project: years behind before construction began .

But the Finnish nuclear lobby is already planning another nuclear energy adventure: the construction of so-called Small Modular Reactors (SMR). Paul Dorfman of the UK UCL Energy Institute and co-author of an SMR study by the Nuclear
Consulting Group estimates that small reactors would provide increasingly expensive energy due to the cost of materials and personnel : the massive investments that would be required to create a supply chain so that replacing the economies of scale of large reactors with the advantage of series production would make the investment risk for SMR even higher than for standard reactors.

Long-delayed Finland Olkiluoto 3 nuclear reactor to start July 2020 – TVO

Long-delayed Finland nuclear reactor to start July 2020 – TVO  https://www.reuters.com/article/finland-nuclear/long-delayed-finland-nuclear-reactor-to-start-july-2020-tvo-idUSL8N24I4LH    PARIS, July 17 (Reuters) – Finnish Teollisuuden Voima Oyj (TVO) said in a statement on Wednesday that the long-delayed Olkiluoto 3 nuclear plant would start generating electricity in July 2020.

TVO said that the Areva-Siemens Consortium that is building the reactor had informed it that nuclear fuel will be loaded into the reactor in Jan. 2020, the first connection to the grid will take place in April 2020, and start of regular electricity production in July 2020.

The EPR reactor in western Finland is already more than a decade behind schedule and had been due to start producing electricity in January 2020.

A similar reactor under construction for French utility EDF in Flamanville, France is also years behind schedule and billions over budget due to a string of major technical problems, including weak spots in its steel and faulty weldings.

In Taishan, China the world’s first EPR reactor went into commercial operation in Dec. 2018 and the second one is expected to go into full operation in the fourth quarter of 2019.

EDF, which has a 30 percent stake in the Taishan reactors, is also building two EPR reactors in Hinkley Point, Britain. (Reporting by Geert De Clercq Editing by Bate Felix)

Finland’s nuclear waste burial site to store wastes from two nuclear power plants

Nuclear waste firm plans big investment at Olkiluoto final disposal site https://yle.fi/uutiset/osasto/news/nuclear_waste_firm_plans_big_investment_at_olkiluoto_final_disposal_site/10847558 26 June 19

According to Posiva, the decision will lead to the world’s first safe final disposal system for nuclear waste.  Nuclear waste firm Posiva is to spend some 500 million euros on a production facility for spent fuel handling at its underground Onkalo site, adjacent to the Olkiluoto nuclear power plant in Eurajoki, southwest Finland.

The company plans to build a final disposal facility and an encapsulation plant, which it says will allow spent nuclear fuel rods to be stored safely for millennia.

Posiva is owned by the utilities TVO and Fortum, which plan to use Onkalo to store waste from Olkiluoto and Loviisa nuclear power plants.

Olkiluoto has two reactors, with a long-delayed third one due to begin operations sometime next year, more than a decade behind schedule. Plans for a fourth reactor have been shelved. Loviisa has two reactors built in the late 1970s. Posiva has said there is no room at Onkalo for waste from the proposed Fennovoima plant in northern Finland, which has yet to receive a construction permit.

“World’s first”

Sections of the Onkalo storage cave that have already been dug out will be upgraded with systems needed for begin the final disposal procedures.

According to Posiva CEO Janne Mokka, the investment decision paves the way for the world’s first safe final disposal system for nuclear waste.

“In Finland, full life-cycle management is a precondition for the production of climate-friendly nuclear electricity. Posiva will execute the final disposal of the spent fuel of its owners’ Olkiluoto and Loviisa nuclear power plants responsibly,” he said in a statement on Tuesday.

The firm estimates that the half-billion-euro construction project will generate some 2,500 person years of employment.

“We expect to award contracts for the most significant works in the near future,” Mokk

Safety problem at Areva’s Olkiluoto nuclear reactor in Finland


WSAU 22nd Feb 2019  Safety problem found at Areva’s Finnish reactor before start-up –
regulator. Finland’s nuclear regulator has identified a safety issue at
Olkiluoto 3, a 1.6-gigawatt reactor built by France’s Areva, now renamed
Orano, and the problem needs to be fixed before the unit can receive a
permit to operate, the regulator told Reuters. The reactor is due to start
producing electricity in January next year after a decade-long delay. Part
of the pressuriser, a primary circuit component of the reactor, is
vibrating at levels that exceed safety limits, said Pekka Valikangas, the
regulator’s section head for nuclear reactor regulation, ahead of an
important assessment which is due to be published on Monday. “The test
results show that these vibrations are not approved,” Valikangas said in an
interview.

Wild mushrooms in Finland still containing high radioactive cesium from Chernobyl nuclear accident in 1986

Watchdog: Wild mushrooms OK to eat despite lingering Chernobyl radiation, YLE, 16 Jan 19, More than 30 years on, radiation from the Chernobyl disaster remains present in Finnish wild foods.

The Finnish Radiation and Nuclear Safety Authority (Stuk) says that fallout from the Chernobyl nuclear accident can still be detected in Finnish foods, but that it accounts for less than one percent of the average annual radiation dose for people in Finland.

The city of Helsinki’s urban environment division said on Monday that two samples of funnel chanterelle (or yellow leg) mushrooms it tested contained levels of radioactive caesium that exceeded the recommended maximum.

According to EU guidelines, food products offered for sale should not contain more than 600 becquerels per kilo (Bq/kg) of caesium-137. Mushrooms picked in Pälkäne in Pirkanmaa, south-central Finland had a reading of nearly 1,000 Bq/kg. Meanwhile those picked in Hyvinkää, some 60 km from the capital, contained 1,300 Bq/kg. Wild produce from around the country is widely sold at marketplaces in the capital…… https://yle.fi/uutiset/osasto/news/watchdog_wild_mushrooms_ok_to_eat_despite_lingering_chernobyl_radiation/10598680

Radioactive reindeer in Finland and Norway

Rudolph the radioactive reindeer https://beyondnuclearinternational.org/2018/12/16/rudolph-the-radioactive-reindeer/ December 16, 2018

Dosed by Chernobyl and atomic tests, reindeer and their herders are carrying a heavy nuclear burden, By Linda Pentz GunterFallout from Soviet atomic bomb tests over the Arctic Ocean, compounded by the 1986 Chernobyl nuclear power plant explosion, have left reindeer too radioactive to eat, even today. That may be good news for the reindeer, sort of. But it’s bad news for the indigenous Laplanders in Finland and Sami herders in Norway, who carry high levels of radiation in their own bodies as well as in the reindeer on which they depend for sustenance and sales.

Reindeer carry heavy radioactive doses, mainly of cesium-137, because they devour lichen, moss and fungi, which bioaccumulate radioactive deposits from fallout. Norway’s radioactive contamination is primarily from Chernobyl, made worse because it was snowing heavily at the time of the April 26 accident. 

The Sami story is beautifully explained in this stunning photo essay by Amos Chapple and Wojtek Grojec for Radio Free Europe/Radio Liberty.

As the essay describes it, despite the length of time since the Chernobyl disaster, the fallout is a nasty gift that keeps on giving. “In 2014, there was a huge spike in radiation levels that scientists put down to a bumper season for mushrooms. Hundreds of Norwegian reindeer intended for slaughter had to be released back into the wild.”  Levels apparently shot from 1,500 becquerels per kilogram to 8,200.

A video of Chapple and Grojec’s work, on Tech Insider, also explains the impact of cesium-137 fallout on reindeer and their herders. [0n originall] 

Unfortunately, Norway’s “allowable” radiation standards are far higher than in other parts of Europe, at 3,000 becquerels per kilogram of food compared to the EU standard of 600 becquerels. When Chapple and Grojec were compiling their story, the herd they visited was testing at 2,100 becquerels, passing the Norwegian test for “safe”. The authors say that the higher levels were established by the Norwegian government in “response to radiation levels in reindeer that threatened the very existence of the Sami herders.”

This practice of simply moving the radiation goalposts to make dangerous levels safe still goes on today, of course, most notably in Japan. As was pointed out in an earlier story on our site, the Japanese government, eager to show the world that the Fukushima region could quickly be made safe for habitation, simply raised the “allowable” annual exposure rate from 1 millisievert to 20, an entirely unacceptable dose for most people, especially women and children.

In Finland, most of the persistent radiation levels are due to atomic testing during the Cold War. Measurements continue to be taken among the Lapland reindeer herders where cesium levels are ten times higher than in the rest of Finland. Although cesium levels in humans were a shocking 45,000 becquerels per kilo in the 1960s according to one report, they still hover at over 1,000 today.

The reduction in slaughter of reindeer comes with other side effects as well. As far back as 1997, it was already being observed that the increase in reindeer population, leading to “Over-grazing and trampling, is causing more damage to the fragile tundra than some of the world’s most seriously polluting factories,” wrote Geoffrey Lean in The Independent.

Now, as Russia begins using floating nuclear reactors to plunder the Arctic Ocean for oil, the region has been placed under threat of a radioactive catastrophe again. From both an economic and health perspective, neither the reindeer nor their indigenous herders can afford a second assault.

Finland’s super-expensive Olkiluoto nuclear project delayed yet again

World Nuclear News 29th Nov 2018, The start of regular electricity generation at the Olkiluoto 3 (OL3) EPR has been pushed back by a further four months and is now expected to begin
in January 2020, Finnish utility Teollisuuden Voima Oyj (TVO) announced
today.

Last month, the plant’s supplier – the Areva-Siemens consortium –
announced it wanted to update the schedule for completing the unit as
commissioning tests were taking longer than planned. TVO said it has been
informed by the Areva-Siemens consortium that fuel will now be loaded into
the reactor core in June 2019, with grid connection to take place next
October, and the start of regular electricity generation scheduled for
January 2020.

Under the previous schedule provided by the plant supplier in
June this year, fuel loading was expected in January 2019, grid connection
in May and the start of regular electricity production in September.

“This research comprehensively described the occurrence of extreme weather and climate events and aspects of sea level rise that are relevant from the view point of safety of nuclear power plants.

Studies about the frequency, intensity, and spatial and temporal variation of the extreme weather events and their combinations were carried out utilising instrumental meteorological observations, a 1 200-year long preindustrial control simulation and future climate model simulations.

In addition to the role of natural climate variability, the study clarified the influence of human-induced climate change on extreme weather events and sea level values. The longest future climate and sea level projections extend to the end of the 21st century.

According to them, the daily maximum temperatures and the length of the longest hot spells will clearly increase in Finland. The largest changes, however, are projected for the wintertime minimum temperatures. During summer there will be more intensive precipitation events and during winter more frequent precipitation days. The mean sea level is projected to rise, the change depending on the location along the Finnish coastline. Uncertainty ranges in the mean sea level scenarios are large mainly due to uncertainties in the future behaviour of the continental ice sheets.” end quote. Please see original link above.

Yet more delays for Finland’s troubled Olkiluoto nuclear power project

Finnish Olkiluoto-3 nuclear unit tests slipping behind schedule: TVO https://www.spglobal.com/platts/en/market-insights/latest-news/electric-power/100418-finnish-olkiluoto-3-nuclear-unit-tests-slipping-behind-schedule-tvo, Elaine Hiruo –Jonathan Dart

HIGHLIGHTS

New final phase schedule due in December

Too early to say if first power tests delayed

Output schedule ‘available ahead of commercial op’

London — Areva-Siemens is to provide a new schedule in December for the final phases of the 1.6-GW Finnish Olkiluoto-3 nuclear reactor after slippage in its commissioning tests, owner operator TVO confirmed Thursday.

This could potentially push back first delivery of power in tests currently scheduled from May 2019, “but we won’t know this until December,” TVO spokesman Pasi Tuohimaa told S&P Global Platts.

Previously TVO has said test production over a roughly five-month period could account for 10%-15% of Finland’s annual electricity needs ahead of full commercial operation, or 2-4 TWh.

Such is the potential volume at risk that TVO is to put up a schedule of Olkiluoto-3’s production tests six months before commercial operation, Tuohimaa said. He stressed that at this stage it was impossible to assess accurately how much electricity would be produced during testing.

“The completion of the commissioning tests has not been progressing according to the updated schedule for commissioning by the plant supplier Areva-Siemens Consortium,” TVO said in a statement late Wednesday.

The operator could not say whether “rebaselining” of the final phase schedule would affect the current September target for the start of commercial operation at the plant, which is already almost 10 years behind the original schedule and three times over the original Eur3.2 billion budget.

Neither could TVO say whether test production of electricity at varying power levels from May 2019 would be affected by the re-scheduling.

In June 2017, TVO said Olkiluoto-3 would begin commercial operation in September 2019, rather than in May of that year as expected. Hot testing had taken longer than expected, it said.

Q2 2019 Nordic baseload power on the NASDAQ futures exchange traded Thursday 0900 GMT at Eur36.40/MWh, down 30 euro cent from two trades earlier in the European morning.

Delay at Olkiluoto nuclear project French-German consortium Areva-Siemens unable to complete tests

Nuclear plant delay, YLE  4 Oct 18  Daily Turun Sanomat reports that the start of regular power production at Finland’s biggest nuclear reactor, Olkiluoto 3, may be pushed back yet again.

TVO – the owner of the power plant – said the French-German consortium Areva-Siemens has not been able to complete commissioning tests at the Eurajoki site as planned, the paper says. According to TVO, it is still unclear whether the supplier’s test delays will affect the launch of the plant, which has been scheduled for September 2019.

The project in western Finland has been hit by repeated delays, spiraling costs and legal disputes. The construction of the 1,600 MW reactor began in 2005, and initially it was scheduled to start producing electricity in 2009.

On Tuesday, Finland’s Radiation and Nuclear Safety Authority expressed concerns about the safety culture at energy company Fennovoima, which seeks to build a nuclear power plant in northern Finland. https://yle.fi/uutiset/osasto/news/thursdays_papers_bus_driver_walk-out_nuclear_power_plant_delay_and_finns_in_drug_bust/10438247

Finland company looks to China’s lucrative nuclear decommissionig and nuclear waste market

Finnish firms target Chinese radwaste market, WNN, 23 August 2018

Based on expected installed nuclear generating capacity of 50 GWe by 2020, China’s annual used fuel arisings will amount to about 1200 tonnes at that stage, the cumulative total being about 14,000 tonnes then.

“As China becomes increasingly mindful of environmental integrity and reduces its use of fossil fuels, [its] zero-carbon nuclear energy solution requires enhanced focus on radioactive waste management,” the companies said in a joint statement. “Finnish expertise has an important role in disposing of Chinese radioactive waste and building a cleaner future together with shared respect for nature and the environment.”……….Finnish waste management company Posiva – jointly owned by Fortum and TVO – launched Posiva Solutions in June 2016. The business, it said, would “focus on the marketing of the know-how accumulated from the design, research and development efforts in the final disposal of used nuclear fuel, as well as on associated consulting services”. http://www.world-nuclear-news.org/Articles/Finnish-firms-target-Chinese-radwaste-market
