Operational Ban Lifted on Major Japan Nuclear Plant

by Sydney Leimbach | Jan 3, 2024
Japan’s nuclear power regulator has lifted its operational ban on Tokyo Electric Power’s (Tepco) Kashiwazaki-Kariwa nuclear plant, the largest nuclear site in the world, after shutting it down about three years ago due to safety concerns.
The plant, which reportedly has a capacity of 8.2 gigawatts, was the only operable atomic power station in the country when it was shut down. It had previously been offline since the 2011 Fukushima disaster caused all nuclear power plants in the country to cease operations.
Tepco was barred from operating the Kashiwazaki-Kariwa plant in 2021 after the Nuclear Regulation Authority reportedly found safety breaches such as failing to protect nuclear materials and finding an unauthorized staff member accessing sensitive areas of the plant.
Last week, Japan’s Nuclear Regulation Authority found that counterterrorism and safety measures had since been improved at the plant after conducting inspections. Before the plant may come back online, however, consent must be achieved from local governments in Niigata, Kashiwazaki city, and Kariwa village, where the plant is located.
“The government will seek the understanding and cooperation of Niigata prefecture and local communities, emphasizing ‘safety-first’,” said Yoshimasa Hayashi, the government’s top spokesperson, in a Reuters report.
The company has compiled a report on the causes of the infractions that led to its ban and how improvements have been made since. Shares in Tepco dramatically increased when the Nuclear Regulation Authority indicated that the ban would be lifted, especially as the country works to revitalize its nuclear power profile, https://www.environmentenergyleader.com/2024/01/operational-ban-lifted-on-major-japan-nuclear-plant/

Following earthquake, Japan’s nuclear reactors escaped serious problems – THIS TIME.
Japan’s nuclear power plants largely undamaged following quake
BY ERIC JOHNSTON, STAFF WRITER, Japan Times, 2 Jan 24
Japan’s nuclear power plants along the Sea of Japan coast escaped serious damage in the New Year’s Day earthquake that struck the Noto Peninsula in Ishikawa Prefecture.
But the 7.6 magnitude quake, which triggered tsunami warnings from Hokkaido to Kyushu and led to evacuations in nine prefectures, could once again spark public concern about the safety of nuclear power in an earthquake-prone country at a time when Prime Minister Fumio Kishida plans to ramp up its usage as part of his “green transformation” policy.
In Ishikawa Prefecture, Hokuriku Electric Power’s Shika nuclear plant saw its electricity system partially disabled following the quake, but no major abnormalities have been reported. The plant’s No. 1 and No. 2 reactors were offline prior to the quake.
The Nuclear Regulation Authority (NRA) reported that Shika plant workers heard what sounded like an explosion, and then smelled something burning near a transformer that received electricity for use in the No. 2 reactor. Staff checking the area discovered the fire extinguishing system had been activated.
No fire was detected but the reactor’s electricity supply was partially disabled. Hokuriku officials believe pressure inside the transformer increased due to the tremor. This triggered a device to release the pressure, causing a loud noise and activation of the fire extinguishing system rather than an actual fire.
Electric power for equipment critical for the plant’s safety was secured through other systems, and cooling pools where spent nuclear fuel is stored continued to operate. Hokuriku Electric officials said Monday they were assessing the damage but that there was no change in the readings of the plant’s monitoring posts, and that no external radiation had been detected. However, of the 101 radiation monitoring posts in the plant’s vicinity, 13 are no longer operational. As of Tuesday, the cause was still unknown.
At Tokyo Electric Power Company Holdings’ Kashiwazaki Kariwa Nuclear Power Station in Niigata Prefecture, home to seven nuclear reactors — all of which were offline before the quake — plant officials confirmed Monday that water from a spent fuel pool spilled over due to the earthquake, but that no abnormalities in operation had been detected………………………………………………..
While the nuclear power plants avoided damage, the New Year’s Day quake and tsunami warnings brought back memories of the devastating Great East Japan Earthquake and triple meltdowns at the Fukushima No. 1 power plant, and could revive doubts about the nuclear industry — especially at a time when the government has plans to use more reactors, many located on the Sea of Japan coast, that have been offline since the quake on March 11, 2011.
Last February, the Kishida Cabinet approved its green transformation policy, which would extend the lifespan of nuclear reactors beyond 60 years and replace those that get scrapped. It was a major reversal of the policies that went into place following the 2011 disaster.
Currently, 12 nuclear power plants have been officially restarted since 2011, while five have received permission to restart and are undergoing final preparations to do so. Another 10 reactors are still undergoing inspections for a possible restart. Nine reactors have not applied for restart, and 24, including 10 Tepco reactors in Fukushima Prefecture, are being decommissioned.
Systems to supply power to nuclear plant in Ishikawa partially unusable
NHK News, Tuesday, Jan. 2, 2024
The operator of the Shika nuclear power plant in quake-hit Ishikawa Prefecture says systems to supply electricity to the facility from outside sources remain partially unusable.
But the utility says electricity continues to be supplied to the plant through other means and that sources of power for important safety equipment are secure.
Hokuriku Electric Power Company held a news conference on Tuesday, one day after a magnitude 7.6 earthquake struck the prefecture.
Both of the No.1 and No.2 reactors at the plant, which are located in the town of Shika, had been taken offline long before the earthquake…………………………..
Hokuriku Electric officials said the pipes of two transformers used for the two reactors to receive electricity from outside have been damaged due to the earthquake, with oil for insulation and cooling leaking out.
The officials said the oil leakage amounts to 3,600 liters at the No.1 reactor and 3,500 liters at the No.2 reactor. They said systems using the two transformers remain unable to receive electricity.
They also said both reactors are receiving electricity from other means, adding that emergency diesel generators have enough fuel to last seven days.
The officials say there are no problems with the systems for cooling spent nuclear fuel. more https://www3.nhk.or.jp/nhkworld/en/news/20240102_33/
UK Nuclear Output Slumps to 42-Year Low
- More reactors are due to be decommissioned in a few years
- EDF has warned of delays to its new Hinkley Point plant
Bloomberg, By Rachel Morison, January 3, 2024
Power output from the UK’s nuclear power plants slumped to the lowest in more than four decades last year, potentially increasing a reliance on fossil fuels that will make it more difficult to reach the nation’s net zero emissions target.
Output shrank to about 37 terawatt-hours after two stations closed, dropping below 40 terawatt-hours for the first time since the early 1980s, according to data from the government and the UK unit of Electricite de France SA. …the country’s current fleet of five nuclear plants scheduled to shrink to just three by the end of 2026,…
The UK, which has a target to reach net zero emission by the middle of this century, wants to build as much as 24 gigawatts of new nuclear capacity by that time. The government is due to publish a roadmap on how it intends to achieve that ambitious target.
But construction takes many years and is often beset by cost overruns and delays. To reach the goal, developers would need to add 16 gigawatts in the next decade at a cost of more than £150 billion ($190 billion), according to estimates from Aurora Energy Research.
“With revenues materializing around a decade after the Final Investment Decision, this generally makes nuclear a very different investment case to banks compared to other low-carbon generation technologies, one which fewer lenders are willing to consider,” said Ashutosh Padelkar, senior associate at Aurora. “It would be extremely challenging if not impossible to deliver 24 gigawatts of nuclear capacity by 2050 without the government taking most of the burden.”…………
Most of the current atomic fleet is reaching the end of it’s operating life. EDF has spent about £7.5 billion on life extensions and maintenance since 2009, when it acquired the current fleet.
EDF’s Hinkley Point C is the first project to be constructed in more than three decades. Startup of its two reactors is due in 2027 and 2028, though the utility has warned that may be pushed back by more than a year. https://www.bloomberg.com/news/articles/2024-01-03/uk-nuclear-output-slumps-to-42-year-low-in-threat-to-net-zero?embedded-checkout=true
More than half of eligible schools enlist in new solar scheme in Ireland

More than half of eligible schools enlist in new solar scheme in Ireland.
Ireland’s Department of Education says that just over 900 schools out of
1,600 eligible facilities have signed up to participate in the
government’s first round of the Solar for Schools Programme, a nationally
funded scheme to cover the costs of 6 kW roof-mounted solar installations.
Panels would be connected to the electricity grid, leading to €1,200
($1,310) to €1,600 per annum in savings, according to the government.
Schools from 11 districts could sign up in the first application round
which opened in mid-November and is expected to reach completion in May
this year.

DOE docs: Carbon removal proposal bets on rare nuclear reactors
E & E News, ClimateWire, By Corbin Hiar | 01/03/2024
A climate technology startup aims to suck carbon from the atmosphere using a new type of nuclear power plant that’s never been built in the United States.
The use of so-called small modular reactors could provide a steady supply of electricity that’s free of climate pollution to a major carbon removal facility planned in Wyoming, according to Energy Department documents obtained by POLITICO’s E&E News. But some experts worry that relying on a novel nuclear plants could jeopardize the development of a federally funded proposal to develop direct air capture, an emerging industry that uses fans, filters, heat and piping to siphon carbon dioxide from the sky.
“It adds complication upon complication,” said Wil Burns, the co-director of American University’s Institute for Carbon Removal Law and Policy. “You’re starting off with a complex new technology, and now you’re trying to wed another complex technology, including one that’s in transition.”
The interest in small nuclear reactors by CarbonCapture, the lead developer of the carbon removal proposal, is among several previously undisclosed components of its initial concept for the Wyoming Regional Direct Air Capture Hub, outlined in documents released by the DOE via a Freedom of Information Act request.
The revelation comes as the Biden administration is moving to pour billions of dollars into commercializing direct air capture technologies while also resuscitating the nuclear power industry. The administration considers the success of both, which is far from assured, to be essential in the fight against climate change.
There are currently only two commercial-scale direct air capture facilities in operation worldwide that remove carbon dioxide from the air and store it underground or in long-lasting products like concrete. Building direct air capture plants and other types of carbon removal facilities — while rapidly weaning the world off of fossil fuels — is necessary to avoid the worst impacts of global warming, climate scientists say.
In theory, nuclear power plants could provide direct air capture developers with a steady supply of carbon-free electricity and heat.
Yet only two new reactors have come online in the U.S. over the past quarter-century. Small modular reactors have been promoted by the administration and nuclear energy advocates as a way to address concerns about cost and waste that derailed the nuclear industry in the 1990s.
That vision was thrown into doubt in November when a nuclear power company — facing spiraling costs and fleeing customers — pulled the plug on a $1.4 billion project to develop the nation’s first small modular reactors………………………………………………………
For Burns, who also teaches at Northwestern University and has reviewed carbon removal business plans for the payments company Stripe, the new details about CarbonCapture’s initial project designs suggest more due diligence is warranted.
“Government needs to be thinking this through before we commit a lot more money,” he said…………………………………………… https://www.eenews.net/articles/doe-docs-carbon-removal-proposal-bets-on-rare-nuclear-reactors/.
‘100-200,000, Not Two Million’: Israel’s Finance Minister Envisions Depopulated Gaza
Israel’s far-right Finance Minister Bezalel Smotrich joined a growing list of senior lawmakers who expressed support for large-scale transfer of Gaza’s civilian population as a solution to Israel’s post-war security concerns.
Finance Minister Bezalel Smotrich said that Israel must control the territory in the Gaza Strip and significantly reduce the number of Palestinian residents in Gaza.
In an interview to army radio, the far-right minister said that his “demand” was for the Gaza Strip to stop being a “hotbed where two million people grow up on hatred and aspire to destroy the State of Israel.”
Without outlining his preferred method, Smotrich then suggested that the removal of around 90 percent of Gaza’s residents would help achieve his goal. “If there are 100,000 or 200,000 Arabs in Gaza and not two million, the whole discourse about the day after will be different,” he said.
The Religious Zionism party chairman then noted that in order to regain security, Israel must control the Gaza Strip, and that “in order to control the territory militarily over time, you must also have civilian presence there.”
Smotrich’s comments are the latest in a growing list of troubling remarks by Israeli lawmakers to seemingly support expelling Gazans en masse out of the Strip in order to ensure Israel’s security after the war.
“Civil nuclear power” has always been a cover story for wasting public money on nuclear weapons.
The ride aboard our “Pale Blue Dot”
By Walt Patterson, Beyond Nuclear 31 Dec 23
“…………………………………………………………………………………………………… Eighty-seven years after I got here the blue dot is now in serious trouble. Not the dot itself, but all of us creatures riding on it. My eighty-seven year ride coincides precisely with the time we have been living with the knowledge about nuclear fission. As I have contemplated it most of my life I have been compelled to conclude that nuclear electricity, so-called nuclear power, has never been a normal economic activity, it has never paid its way, and still does not, it has always relied on vast injections of money and resources from taxpayers and electricity users, decreed by governments.
Civil nuclear power has been in effect a cover story, to disguise the true reason for pouring so much of our wealth into this dangerous sinkhole. In the eyes of governments, the key nuclear activity has been to stockpile terrifying quantities of nuclear explosives for use as weapons, nuclear political power, in which someone says, in effect, unless you do what I want, or give me what I want, I’ll obliterate this blue dot.
As climate change makes more and more of the blue dot uninhabitable, conflicts are breaking out world-wide. We have to hope that some people, some of our fellow dot-riders, some states-people, can find a way to defuse the nuclear threat.
Best wishes for a better 2024 — Walt. https://beyondnuclearinternational.org/2023/12/31/the-ride-aboard-our-pale-blue-dot/
COP28’s Nuclear Energy Promise Is Still a Long Way Off

The role nuclear energy might play in the future global energy mix should be supported by realistic analysis not on hope about what might be accomplished on hypothetical pathways.
During the past decade, the industry has shifted its
attention from constructing relatively large scale ~1,000 MWe pressurized
and boiling water reactors to considering small modular reactors, SMRs ≤
300 MWe. It is widely believed that SMRs will be of lower cost than the
disastrous cost levels experienced at the Vogtle, GA, and abandoned V.C.
Summer, South Carolina, plant construction. Accordingly, SMRs have
attracted a great deal of private and federal investment, but low overnight
capital cost has yet to be demonstrated.
Optimism arose beginning in
mid-2022 that nuclear deployment in the United States was entering a period
of growth. The GE-Hitatchi BWRX-300 MWe SMR was selected for deployment by
the Ontario Power Group at its Darlington site. It is under consideration
by Saskatchewan’s SaskPower and the TVA at Clinch River, Tennessee.
NuScale, partnering with Utah Associated Municipal Power Systems (UAMPS),
planned to combine twelve 77 MWe pressurized water modules to produce a 924
MWe plant at the Department of Energy’s (DOE) Idaho Falls ID site by
2030. The DOE’s GEN IV Advanced Reactor Demonstration Program selected
X-Energy’s Xe-100 high-temperature gas reactor (four 80 MWe modules
ganged together to produce 320 MWe) and TerraPower’s 345 MWe molten salt
Natrium reactor, each to receive $110 million 50/50 cost share. X-Energy
has selected DOW’s Seadrift TX chemical plant as its first location.
TerraPower was selected at a retired coal plant at Kemmerer, WY, which
PacifiCorp will operate.
Toward the end of 2023, expectations collapsed.
COVID-19, unexpected inflation, and high borrowing rates have caused all
the early participants to extend their anticipated completion dates, exceed
initial cost targets, and indicate additional financing will be needed.
After the massive budget outlays of the Bipartisan Infrastructure Act and
Inflation Reduction Act legislation, it is unlikely that major additional
support will come from the federal government.
In November, NuScale
announced the cancelation of its UAMPS project, delivering a major setback
to nuclear energy expectations. The DOE has provided $232 million for the
project since 2020, and the department has backed the project with a $1.4
billion cost-share deal. The project was abandoned because of the
substantial cost overruns and the unwillingness of UAMPS members to pay
higher prices for the off-take electricity.
Accordingly, the United States
will not have acquired a record declining unit cost on SMR reactors, at
least until the mid-2030s. In sum, we are confronted with an aspirational
goal for the growth of international nuclear energy deployment at
mid-century and a decidedly guarded assessment of nuclear energy progress
today based on conditions in the United States, the country with the
largest deployment of nuclear reactors and a history of leading the world
in nuclear technology. The role nuclear energy might play in the future
global energy mix should be supported by realistic analysis, not hope about
what might be accomplished on hypothetical pathways.

EDF using Pontins Brean Sands has ‘big determinantal impact’ on local economy, tourism firm fears
It is unclear when the site will return to
being a holiday park. The continued use of Pontins Brean Sands to house
hundreds of Hinkley Point C workers is reportedly having a “big
determinantal impact” on the local economy, according to one tourism firm.
Up to 900 staff from Hinkley Point C have been living at Pontins Brean
Sands and are expected to be there across 2024 and perhaps beyond. The
holiday resort has seen a massive refurbishment of the chalets worth around
£2 million, which saw new kitchens, bathrooms, furniture, TVs, and new
Wi-Fi access installed. Yet Discover Brean has hit out at the continued use
of the site to Hinkley Point C workers and noted its impact on the local
economy and nearby traders.

Backing the wrong horse: Government doubles Sizewell C funding on nuclear bad news day

Given the Hinkley debacle, the NFLAs regret that Mr Bowie did not put his shovel to good use by burying the Sizewell project, but instead, like many reckless gamblers, Ministers and senior civil servants at the Department of Energy Security and Net Zero have chosen to blow more taxpayers’ money on a losing prospect, doubling their bet on Sizewell C to £2.5 billion.
The UK/Ireland Nuclear Free Local Authorities were incredulous to learn that government ministers chose to back Sizewell C with a further £1.3 billion of public money on the same day (23 January) French nuclear operator EDF announced that Sizewell’s older twin sister, Hinkley Point C, would begin operating even later and at an even greater cost.
The public relations team handling Hinkley Point C announcements at EDF Energy must have a thankless task as theirs is seemingly a role that involves continually dispensing bad news. Yesterday’s https://www.edf.fr/en/the-edf-group/dedicated-sections/journalists/all-press-releases/hinkley-point-c-update-1 took the biscuit (though whether the PR team could console themselves with any given the state of the corporate finances is debatable; humble pie maybe?)
In the latest in a long litany of gloomy announcements portending further cost and delivery overruns, the company has now advised that the expected cost of delivering Hinkley Point C has increased by anything from £5-9 billion (your guess is as good as theirs) or ultimately between £31 and £35 billion. But this is based on 2015 estimates, so with inflation the bill might run to £46 billion at today’s prices. And the anticipated year in which Reactor 1 might start generating has slipped from the summer of 2027 to sometime never in 2029, with Reactor 2 coming online about one year later (or maybe not).
Interestingly our friends in Stop Sizewell report that Nuclear Minister Andrew Bowie told them recently on his whistlestop visit to Suffolk, bearing a ceremonial shovel, that Hinkley would come online in the late 2020s or early 2030s, and even the Telegraph and Guardian have reported that the plant will not be operational until the next decade.
Rather unconvincingly EDF claims that ‘The project continues to capitalise on the experience gained from construction of the 4 other EPRs around the world’ which is hardly encouraging as Taishan-1 in China experienced a serious accident which led to its shutdown for many months; Flamanville-3 in France, started in 2007 and expected to commence generation in 2012, is only now about to start loading fuel after an unhappy history of faults and compromised quality control; and Olkiluoto-3 in Finland, begun in 2005 with a start date of 2010, was only finished last year after a prolonged construction period which included a bitter contractual dispute about the apportionment of the massively spiralling costs, followed by a corporate bankruptcy.
Given the Hinkley debacle, the NFLAs regret that Mr Bowie did not put his shovel to good use by burying the Sizewell project, but instead, like many reckless gamblers, Ministers and senior civil servants at the Department of Energy Security and Net Zero have chosen to blow more taxpayers’ money on a losing prospect, doubling their bet on Sizewell C to £2.5 billion.
Clearly, DESNZ is unaware that lumbering nuclear white elephants are not the best runners to back in a race, and that renewables, provided with equal financial encouragement, will romp home by a mile every time. Given its latest foolhardy behaviour, the NFLAs now venture to suggest that DESNZ be once more swiftly renamed – this time to the Department of No Energy and Zero Sense.
