  1. #Carbon14: Another underestimated danger from #nuclear reactors

    "There are a number of radionuclides released from nuclear energy facilities. This paper highlights carbon-14 for a number of reasons:

    - Carbon-14 is radioactive and is released into air as #methane and #CO2

    - Before 2010, carbon-14 releases from nuclear reactors were virtually ignored in the United States. Today only estimates are required and only under certain restrictive circumstances.

    - There is no good accounting of releases to date, so its impact on our health, our children’s health, and that of our
    #environment remains unknown, yet environmental measurement is possible, but can be challenging under certain
    conditions.

    - Carbon-14 has a half-life of over 5700 years and the element carbon is a basic building block for life on earth. Therefore, “it constitutes a potential health hazard, whose additional production by #anthropogenic sources of today will result in an increased #radiation exposure to many future generations.”

    - Like #tritium, it can collect in the tissues of the fetus at twice the concentration of the tissues in the mother, pointing to its
    disproportionate impact on the most vulnerable human lifecycle: the developing child.

    The element carbon is found in all organic substances. Carbon is also a primary constituent of #GreenhouseGases that are responsible for #ClimateChange, such as carbon dioxide (CO2) and methane (#CH4). Carbon-14 (c-14) is a radioactive form of
    carbon that occurs in nature and is also newly formed in nuclear power processes.

    "Carbon-14 is a health concern because it is released from #NuclearPower facilities as radioactive carbon dioxide and methane, traveling readily in the local and global environment.

    "Over time, carbon-14 becomes part of organic material including food, and has a half-life of approximately 5,730 years, decaying by a type of radioactive particle called a beta. Its hazardous life is 10-20 times its half-life, meaning that harmful exposure to man-made carbon-14 can last for hundreds of generations. The radioactive carbon forms as a byproduct of fissioning of uranium fuel, through a process called activation. The final step is a chemical reaction between carbon-14 and oxygen or hydrogen, which forms methane or carbon dioxide. The radioactive carbon-14 formed by this process is brand new and would not exist without nuclear fission.

    "During its long hazardous life, carbon-14 could be responsible for gross physical or
    mental defects, stillbirths and childhood deaths, embryonic and neonatal deaths into the many millions over the life of the isotope.

    "These millions could be underestimated five times or more. Carbon-14 could also be responsible for #leukemia, bone and other #cancers."

  2. A tale of two #NuclearPowerPlants along #LakeMichigan: Extended life and a revival?

    WUWM 89.7 FM | By Chuck Quirmbach

    "This year could be a big year for the status of two nuclear power plants around Lake Michigan.

    "That includes a shutdown plant just 120 miles east of Kenosha that is seeking a first-of-its-kind restart.

    "The year could also be significant for extending the life of #Wisconsin's only working commercial plant, located 95 miles north of #Milwaukee.

    "On the west shore of Lake Michigan, #NextEraEnergy says it still wants a 20-year extension for the two reactors at the #PointBeachNuclearPowerPlant, located north of #TwoRivers, which would keep the site operating until the early 2050s.

    "If that plan sounds familiar, it’s because #WUWM has been reporting on the proposal for about four years. U.S. Nuclear Regulatory Commission (#NRC) approval is still pending.

    "In a written statement this month, Florida-based #NextEra said it has invested hundreds of millions of dollars in Point Beach, 'ensuring it’s ready to produce energy for decades to come.' The company says the plant powers nearly 1 million homes and businesses and provides about 14% of Wisconsin’s electricity.

    "But nuclear power critics, like #KevinKamps of #BeyondNuclear, say there are concerns that key parts of the power production units are too #brittle to last another 20-plus years. He says there’s an alternative.

    "'Point Beach’s electricity could easily be replaced through the expansion of #RenewableEnergy in Wisconsin. It’s ready to go. It would be more effective for the people of Wisconsin. It would certainly be much safer,' Kamps says.

    "On the east shore of the lake, the #PalisadesNuclearPlant in #CovertTownship, Michigan, shut down nearly three years ago. But at the urging of some federal, state, and local officials, the Biden administration has provided a $1.5 billion loan to Holtec International, which bought the mothballed plant from the utility Entergy, so Holtec can try to restart Palisades.

    [...]

    "A key concern appears to be the damaged steam generator tubes at Palisades, which are likely to need repair or replacement. On Jan. 14, Holtec and the NRC are scheduled to discuss the matter.

    "The NRC says Holtec will have to prove the plant is safe.

    "Incoming President Donald Trump has made conflicting statements about nuclear power, so it’s unclear if he will try to get the NRC to favor either of the Lake Michigan plants."
