Harris nuke flaw “fixed” that wasn’t found for a year

Less than 500 miles from here in NC, what else haven’t they found if ‘Duke Energy’s examination a year ago “was supposed to have found that problem then and fixed it”‘? This was a ‘a quarter-inch spot the NRC and the company describe as a “flaw” in the reactor vessel head, which contains heat and pressure produced by the nuclear core’s energy.’ When a solar panel has a quarter-inch flaw, you get a tiny percentage less electricity, not the risk of radiation leak or worse. Would you rather have two more nukes at the same site, run by the same company that can’t run the one it’s got safely, or solar power instead?

Plus where is the advantage of baseload capacity when Harris 1 has only been up 27.41% for the past month (NRC data), which is hardly better than the approximately 20% sun hours per day for solar power in North Carolina this time of year. Given the low and continually-dropping cost of solar panels, Duke could simply over-provision distributed solar panels and get way more than 20% or 27.41% effective power, and get that on budget and on time.

Heat shuts baseload nuclear plants

Baseload nuclear plants can’t take the heat! Meanwhile, zero stories of solar plants shutting down due to heat. Quite the opposite: more sun, more solar power!

Scott DiSavino wrote for Reuters 18 July 2012, Four U.S. power reactors shut & NYC sweats during heat wave,

Several nuclear plants on the U.S. East Coast shut down by early Wednesday and New York’s Consolidated Edison power company reduced the voltage in parts of Manhattan as the obsessive heat wave stressed the region’s power system.

Despite the shutdown of four giant nuclear reactors in New York, Pennsylvania, Maryland and South Carolina, the power systems delivered the juice needed by the regions’ homes and businesses to keep air conditioners humming on the projected last day of a brutal heat wave.

Then there’s this excuse:

Although the heat makes it more difficult to use the warmer river water to cool power plants and can stress power lines due to high usage, the reactors did not necessarily shut due to the heat.

They shut down due to faulty sensors, leaks, or unknown causes, and that’s somehow better?

Meanwhile, solar just keeps generating. I’ve never heard of a wind plant shutting down due to heat, either.

Remind me again, why is Georgia Power’s and Southern Company’s bet-the-farm risk on new nukes at Plant Vogtle a good idea? Wasn’t it supposed to be about dependable power?

It’s only going to get hotter: time for solar power

Looks like the heat wave is going to continue for a while, according to NOAA’s maximum heat index forecasts. Reuters wrote today,

A heat wave baking the eastern United States in record temperatures is set to continue on Sunday after deadly storms killed at least 12 people, downed power lines from Indiana to Maryland and left more than 3 million customers without power….

Utilities in Ohio, Virginia and Maryland described damage to their power grids as catastrophic.

Record Georgia temperatures above 100 degrees

Driving north Friday, the temperatures kept getting hotter. John C. Griffin recorded these temperature signs, used here by permission. Friday 29 June 2012:

I can attest it was still over 100 in Macon after dark Friday.

And it only got worse Saturday 30 June 2012:

That’s 107 on Friday and 111 Saturday in Macon, where the previous record high for June was 106.

You know, Macon, where Georgia Power is still “studying” and “experimenting” with solar power. Solar power that continues to generate in the heat with no water use. Solar power that Continue reading →

Waycross animal shelter problems

A simpler kind of animal shelter problem, before and after.

Mike Morrison wrote for Jacksonville.com 4 August 2011, 14 dogs die from heatstroke at Waycross kennel; cooling fans pledged

The heat has killed dogs at the Waycross animal shelter because the kennel isn’t wired to power fans, but a city official said Wednesday that help is on the way.
Okefenokee Humane Society shelter manager Ben Hood said 14 dogs have died of heatstroke in the past three months, including a 7-month-old black Lab that died Wednesday.
“We’ve had record high temperatures this year,” Hood said, “but we don’t have any fans in the kennel because we don’t have any electricity out there.”

And on 10 August he wrote, Continue reading →

Detroit cuts power due to heat: too bad they didn’t have solar

AP reported 10 June 2011, Half the country wilts under unrelenting heat:

Detroit officials intentionally cut power to city hall and a convention center Thursday to prevent the municipal power system from crashing from high energy demand — even though temperatures had tapered to the 70s after two days above 90. Equipment failures knocked out power to several other government buildings and traffic lights in parts of the downtown.
“Because there was a short window of time, we had to make a decision to take some of our customers off to prevent a blackout of the entire city,” Detroit mayoral spokeswoman Karen Dumas said.

Too bad they didn’t have solar, which would have provided peak power at peak load.
