Central #Maine smashes third temperature record in a week

Augusta's high temperature Wednesday tied the warmest temperature ever recorded at the site in the month of November

by Ethan Horton, November 6, 2024

AUGUSTA — "Central Maine set yet another heat-related record Wednesday, marking the third time in the past week a daily temperature record has been broken.

"Wednesday’s unofficial high temperature reached 76 F (24.4 C) in #AugustaMaine and 73 degrees (22.7 C) in #WatervilleMaine, breaking the local record of 72 degrees (22.2 C), set in 2022. The area also broke records on Oct. 31 and Nov. 1, easily surpassing high temperature records set in 1956 and 2003, respectively.

"The #PortlandMaine area broke a record for the entire month Wednesday: The high of 79 degrees F (26.1 C) shattered the warmest temperature ever recorded at the site in the month of November, set at 75 degrees F (23.8 C) on Nov. 5, 2022. Augusta’s high temperature Wednesday tied the area’s all-time November record."

Australia has joined the record setting temperatures occurring around the world this winter

Ben Domensino 23/8: “Oodnadatta’s final maximum temperature today was 38.5°C. This is more than 16°C above average for this time of year. It’s also the highest winter temperature ever observed in South Australia, obliterating the previous record of 36.5°C from the same site on August 12, 1946.”

Cameron H 23/8: “HOTTEST WINTER DAY ON RECORD FOR SOUTH AUSTRALIA🧵🥵:
Oodnadatta saw an absolutely historic 38.5c- *destroys* 1946 record by an insane *2c*

9 out of the 10 AWS’s in SA Pastoral Districts set new records.

At least *4* SA sites saw 36c+! Only 1 site ever exceeded 36c in Winter.”

Update 24/8: Oodnadatta has already eclipsed yesterday’s remarkable record with 38.8c at 1:15pm ACST.

The New York Times has an article on How Heat Affects the Brain. High temperatures can make us miserable. Research shows they also make us aggressive, impulsive and dull.

Record temperatures in #Heatwaves are ocurring in North America, Europe, Middle East, China, Asia this northern summer.

Nuclear watchdog ASN mentions that limits were raised, but the article does not mention those limits. I'll be keeping a watchful EYE 👁️ on this story (and see what I can dig up...!) (From 2023: France’s #NuclearPower stations to limit energy output due to high river temperatures

By Euronews Green with Reuters
Published on 13/07/2023

"EDF is committed to adapting its facilities to #ClimateChange, a company spokesperson said. They added that since 2000, losses due to high river temperatures have represented an average drop of just 0.3 per cent of annual power production.

"The nuclear operator said previously a study it conducted showed last year's higher temperatures had no impact on biodiversity.

"However, a study conducted by French #nuclear watchdog #ASN saw a slight increase in #algae and #plankton growth around the #BugeyPlant during the #HeatWave. Fish populations were also affected through the autumn at the #SaintAlban plant.

"The watchdog stipulated it is currently impossible to distinguish the impact of the raised limits compared to the other #ecological effects of the #HeatWave, but it is continuing to monitor the river #biome."

From 2011:

In Tennessee, #HeatWaves Diminish #Nuclear Power Output

By Alyson Kenward
April 10, 2011

"On July 8, 2010, as the temperature in downtown Decatur, Alabama climbed to a sweltering 98°F, operators at the #BrownsFerry #NuclearPowerPlant a few miles outside of town realized they had only one option to avoid violating their #environmental permit: turn down the reactors. For days, the Tennessee Valley Authority (#TVA), which owns the nuclear plant, had kept a watchful eye on the rising mercury, knowing that more heat outside could spell trouble inside the facility. When the #TennesseeRiver, whose adjacent waters are used to cool the reactors, finally hit 90°F and forced Browns Ferry to run at only half of their regular power output, the TVA hoped the hot spell would last just a few days.

"Eight weeks of unrelenting heat later, the plant was still running at half its capacity, robbing the grid of power it desperately needed when electricity demand from #AirConditioners and fans was at its peak. The total cost of the lost power over that time? More than $50 million dollars, all of which was paid for by TVA’s customers in Tennessee.

"The Browns Ferry nuclear plant, located on the Wheeler Reservoir along the Tennessee River near Athens, Alabama. It has three reactors, each producing about 1000 megawatts of electricity. Credit: Nuclear Regulatory Commission.

“'Last summer, the water in the Tennessee River warmed up early and stayed warm,' says TVA spokesman Ray Golden. 'When it got hot again in July and August, we were impacted by that and had to reduce power at the plant and get it from somewhere else.'

"With river water so warm, the #NuclearPlant couldn’t draw in as much water as usual to cool the facility's three reactors, or else the water it pumped back into the river could be hot enough to harm the local #ecosystem, says Golden. But for every day that the Browns Ferry plant ran at 50 percent of its maximum output, the TVA had to spent $1 million more than usual to purchase power from somewhere else, he says.

"What happened in northern Alabama last summer, at the largest of TVA's nuclear power plants, did not present a human safety concern. Operators knew there was never a risk of an explosion or nuclear meltdown, nor was there a threat of leaking radioactive material. But the prolonged spell of hot weather put the TVA at risk of violating environmental permits, with hefty fines as one consequence and potential harm to the Tennessee River ecosystem as another.

"It’s not the first time high temperatures have affected the performance of the Browns Ferry plant, and extreme heat is a growing concern for power plant operators across the #Southeast. While some nuclear plants can improve their cooling procedures to cope with the intake of warmer water, the upgrades can cost hundreds of millions of dollars and still don’t offer an indefinite defense against extreme heat. Because scientists say the Southeast (like many other parts of the world) can expect to see more frequent and intense heat waves by the end of this century, the problems for nuclear power and the people that rely on it for electricity may only be beginning.

#ExtremeHeat Limits Nuclear Energy Production

"The disaster still unfolding at Japan’s #FukushimaDaiichi nuclear plant has refocused America's attention on nuclear power, calling into question its future role in the country's energy portfolio. Many advocates of nuclear power say that we need to maintain — and even expand — nuclear power to get away from using fossil fuels, such as coal, and to help lower greenhouse gas emissions.

"But nuclear power has a paradoxical relationship with #ClimateChange. Even though it might help mitigate long-term #GlobalWarming, nuclear power is already being challenged by rising temperatures and the increasing number of heat waves around the world. Throughout the last decade, several plants have had to reduce electricity production during heat waves, just when when electricity demand typically reaches peak levels.

“'It’s a dilemma between mitigation of climate change, and adaptation to it,' says Natalie Kopytko, an energy policy doctoral student at the University of York in England. Having recently studied the ways in which climate change could have a negative impact on nuclear power, she says nuclear power is caught in the middle because it could be used to help lower greenhouse gas emissions, but global warming is making the technology less effective at providing electricity."

Nuclear Power Plants: #NRC Should Take Actions to Fully Consider the Potential Effects of #ClimateChange

GAO-24-106326 Published: Apr 02, 2024.

"Climate change is likely to exacerbate natural hazards—such as #floods and #drought. The risks to nuclear power plants from such hazards include damage to systems and equipment that ensure safe operation.

"The Nuclear Regulatory Commission's oversight process includes addressing safety risks at these plants. However, NRC doesn't fully consider potential increases in risk from climate change. For example, NRC mostly uses historical data to identify and assess safety risks, rather than data from future climate projections.

"We recommended that NRC fully address climate risks to nuclear power plants.

"Climate change is expected to exacerbate natural hazards—including heat, drought, #wildfires, #flooding, #hurricanes, and #SeaLevelRise. In addition, climate change may affect #ExtremeCold weather events. Risks to nuclear power plants from these hazards include loss of offsite power, damage to systems and equipment, and diminished cooling capacity, potentially resulting in reduced operations or plant shutdowns.

"The Nuclear Regulatory Commission (NRC) addresses risks to the safety of nuclear power plants, including risks from natural hazards, in its licensing and oversight processes. Following the tsunami that led to the 2011 accident at Japan's #FukushimaDaiichi nuclear power plant, NRC took additional actions to address risks from natural hazards. These include requiring safety margins in reactor designs, measures to prevent radioactive releases should a natural hazard event exceed what a plant was designed to withstand, and maintenance of backup equipment related to safety functions.

"However, NRC's actions to address risks from natural hazards do not fully consider potential climate change effects. For example, NRC primarily uses historical data in its licensing and oversight processes rather than climate projections data. NRC officials GAO interviewed said they believe their current processes provide an adequate margin of safety to address climate risks.

"However, NRC has not conducted an assessment to demonstrate that this is the case. Assessing its processes to determine whether they adequately address the potential for increased risks from climate change would help ensure NRC fully considers risks to existing and proposed plants. Specifically, identifying any gaps in its processes and developing a plan to address them, including by using climate projections data, would help ensure that NRC adopts a more comprehensive approach for assessing risks and is better able to fulfill its mission to protect public health and safety."
