Nebraska Nuclear Plant Flood Defenses Tested

mdsolar tips an article at the NY Times which begins: "Pictures of the Fort Calhoun nuclear power plant north of Omaha, Neb., show it encircled by the swollen waters of the Missouri River, which reached a height of nearly 1,007 feet above sea level at the plant yesterday. The plant's defenses include new steel gates and other hard barriers protecting an auxiliary building with vital reactor controls, and a water-filled berm 8 feet tall that encircles other parts of the plant. Both systems are designed to hold back floodwaters reaching 1,014 feet above sea level. Additional concrete barriers and permanent berms, more sandbags and another power line into the plant have been added. The plant was shut down in April for refueling and will remain so until the flood threat is passed. 'Today the plant is well positioned to ride out the current extreme Missouri River flooding while keeping the public safe,' Nuclear Regulatory Commission spokesman Victor Dricks said on an agency blog this week. But a year ago, those new defenses were not in place, and the plant's hard barriers could have failed against a 1,010-foot flood, the Nuclear Regulatory Commission contends in a yearlong inspection and enforcement action against the plant's operator, the Omaha Public Power District."

    Woot mdsolar is posting another article about nuclear power to spread more FUD!!!

    OK nutcase - go find an article that paints nuclear power in a warm, rose colored blush. That's what Firehose is for. Unfortunately, nuclear power is not getting very good press and for very good reasons. The engineering isn't all that it is cracked up to be and isn't at all what it needs to be. Even with the 'new' flood guidelines, the plant in TFA is only seven feet from breaching the walls. With a billion dollar plant hanging in the balance, I'd like just a bit more breathing room.

    Again, it's not the long term waste problem that's going to kill commercial nuclear power (although that is a big issue that we're not handling well). It's going to be bad engineering decisions pushed on staff because of economic considerations. Short term gain, long term pain.

I mean, some people may be NIMBY about turbines, but man, I am definitely NIMBY for a nuke plant now.

    Well yeah, that's what happens when you consolidate production. Comparing accident rate per plant (implicitly equating one nuclear plant to one coal plant), is basically the same as saying hundreds of people die when a plane crashes while only a few people die when a car crashes, therefore cars are safer. You're ignoring the fact that planes move a lot more people in fewer trips / there are a lot fewer homes around the perimeter of nuclear plants than other types of power plants for an equivalent amount of power generated. If you correctly account for the amount of power generated:

    The U.S. has just 65 nuclear plants (104 reactors) with 101 GW nominal capacity. That's an average of 1550 MW per nuclear plant. Nuclear capacity factor is about 90%, for an average 1400 MW production per plant.

    The U.S. has 1493 coal plants with a nominal capacity of 335.8 GW. That's an average of 225 MW per coal plant. Coal has a capacity factor of 60%-70%, for an average 135-158 MW production per plant. A single nuclear plant is equivalent to 9-10 coal plants.

    If you assume 1 MW wind turbines @ 20% capacity factor, that's an average 0.2 MW production per turbine. A single nuclear plant is equivalent to 7000 1 MW wind turbines.

    If you assume 15% efficient PV panels (nominal 125 W/m^2) with 18% capacity factor (typical for desert southwest), you get 22.5 W/m^2 average production, or an average 22.5 MW production per square km. A single nuclear plant is equivalent to 62 square km of solar panels.

    So if you want to compare cost, risk, and environmental impact equally, you need to compare a single nuclear plant, to 9-10 coal plants, to 7000 1 MW wind turbines, to 62 sq. km of solar panels.
