    Carrfire ground control to Major Trinity:

    'Trinity Power Plant evacuates; water released into Trinity River'


    7:20 p.m. update

    Trinity River to rise as power plant evacuates

    "Emergency water releases into the Trinity River have begun at Lewiston Dam because the Trinity Power Plant has been evacuated due to the Carr Fire, according to the Bureau of Reclamation."

    O Furacão Florence vai atingir a Carolina do Norte, e mais directamente uma área com 12 centrais nucleares! Enfim fica o artigo como reflexão...

    Nuclear Power Plants At Risk Of Direct Hit By Hurricane Florence

    North and South Carolina nuclear power plants are in line for a possible direct hit from Hurricane Florence.

    According to the Nuclear Regulatory Commission (NRC), there are twelve operating nuclear power plants in the Carolinas that make electricity by the continuous splitting of uranium atoms (i.e., a nuclear reaction). These plants generally reside near a body of water—a river, lake, estuary or ocean—because they require a constant source of water for cooling purposes. Without cooling water, a nuclear reactor will overheat, leading to core damage, containment failure, and release of harmful radiation into the environment.

    "Florence will approach the Carolina coast Thursday night into Friday with winds in excess of 100mph along with flooding rains. This system will approach the Brunswick Nuclear Plant as well as the Duke-Sutton Steam Plant," said Ed Vallee, a meteorologist at Vallee Wx Consulting.

    "Dangerous wind gusts and flooding will be the largest threats to these operations with inland plants being susceptible to inland flooding," said Vallee.

    He tweeted a few weather models Tuesday morning that forecasts rainfall amounts 15-40" range in some regions along the coast.

    One of those models is the ECMWF Total Precipitation, which shows the most torrential rain could be situated around the two nuclear power plants in Wilmington, North Carolina.

    Also, there is a significant risk of “a life-threatening storm surge” of up to 20 feet or higher along the coast where the nuclear power plants sit.

    "The latest forecast is projecting that Hurricane Florence will strengthen “to near category 5 strength” before it makes landfall in the Carolinas, and it is being called “a serious threat to lives and property”. It is extremely rare for a hurricane of this intensity to come this far north, and one expert is claiming that Florence “has the potential to be the most destructive hurricane we’ve had in modern history for this region.”

    At this time, the government is warning of “a life-threatening storm surge” of up to 20 feet or higher, “life-threatening freshwater flooding”, and “damaging hurricane-force winds”. But there is another factor that not a lot of people are talking about. There are 12 nuclear power reactors in the Carolinas, including two that are located right along the coast, said Economic Collapse Blog.

    Flooding from the storm could be catastrophic for the nuclear power plants. Excessive amounts of water can damage equipment or knock out the plants' electrical systems, disabling its cooling mechanisms. This is what happened at the Fukushima Dai-ichi plant in Japan as a result of the March 2011 tsunami, causing severe damage to the plant's reactors.

    At 5 a.m. Tuesday, the NHC released a report specifying Florence was about 975 miles east-southeast of Cape Fear, North Carolina, and moving west-northwest at 15 mph. Its center will be wedged between Nassau and Bermuda on Wednesday and approach the coast of South and North Carolina on Thursday, as a possible Category 4/5 storm.

    [​IMG]

    If NHC's computer models are correct, there are more than a dozen nuclear power plants that could be affected by Florence.

    Global + Hurricane Florence Model Track Guidance overwhelmingly shows Brunswick Nuclear Plant and Duke-Sutton Steam Plant could take a direct hit.

    Belgium faces winter blackouts amid nuclear reactor shutdowns
    Emergency plans for homes, roads and industry as country loses 40% of power supply
    Oct 30: https://www.theguardian.com...
    A forced shutdown of one nuclear reactor in the lead up to winter may
    be regarded as unfortunate. But the closure of six of the seven
    reactors responsible for supplying 40% of Belgium’s electricity is
    raising eyebrows, even in a country so prone to chaotic administration.
    An emergency “load shedding” plan has been updated, under which
    motorway lights will be switched off, industrial production suspended
    and rolling three-hour blackouts launched in homes nationwide should
    temperatures drop in the coming months and demand outstrip the now
    limited electricity supply.
    Residents have also been warned bills could increase, despite the
    suggestion that they might need to iron less and use just one pot to
    cook.
    The impending crisis stems from the discovery at the end of last month of “concrete degradation” at the Tihange nuclear power plant, west of Liege, forcing the closure of its three reactors.
    Unfortunately, three of the four reactors at Belgium’s second nuclear
    plant, in Doel, near Antwerp, are out of action due to planned repairs. ...
