Last NRC call about foreign ownership of U.S. nuclear reactors: now until noon today

Call in this morning or send written comments. Here are the previous materials (this URL works; the one in the NRC PR is broken). See also NRC’s PR and Commission Direction. The nuclear industry has been pushing for changes for a year now; see more posts. Rather than relaxing rules on foreign ownership of operating reactors, how about stop accepting foreign nuke parts from the likes of document-forging Doosan, which supplies Plant Vogtle among a dozen or so other U.S. nukes?

Down, up, down again: Arkansas Nuclear One

Entergy announced August 8th that its Arkansas nuke was back up after a man died there in March, but it only made it to 87% power on August 12th and then back to zero yesterday. There’s no NRC event for yesterday’s downtime: what’s going on? Meanwhile, the dead man’s family is suing Entergy, and Entergy is suing its contractors. Sounds like the Plant Vogtle circular firing squad.

THV11 wrote 8 August 2013, Nuclear One unit back on after deadly accident and EBR staff wrote more detail for Energy Business Review 9 August 2013, Entergy restarts Unit 1 at Arkansas Nuclear One power plant,

Prior to restart, the unit needed an extensive restoration, including damage evaluation, repairs to non-nuclear plant components and rescheduling its refueling activities.

The restoration was made compulsory following the collapse of a contractor’s crane on 31 March 2013, while shifting a generator stator out of the turbine building.

Hm, “made compulsory” by whom? NRC? OSHA, which also investigated? Arkansas? Other? Continue reading →

Callaway nuke down since Friday near Kansas City, MO

Where there was black smoke in the turbine building there was fire that shut down a nuclear plant Friday. It’s still down today, with no estimate on uptime. This is after Callaway was shut down most of April and May due to an electrical fault that “injured or affected” four people. It’s only been up most of 4 months out of the past 6. Not so reliable, this baseload nuclear, is it?

Margaret Gillerman wrote for the St. Louis Post-Dispatch 27 July 2013, Callaway nuclear plant shut down after a small fire,

FULTON, MO. • Callaway County’s nuclear plant has been shut down since shortly before midnight Friday when a small fire broke out in the turbine building, authorities said.

No one was injured.

“No personnel were hurt, and no radioactivity was released” above normal operating limits, Barry Cox, senior director of nuclear operations at Callaway, said Saturday. Cox said the fire was in Continue reading →

Ginna nuke down near Rochester, NY

We still don’t know what tripped the control rods on Constellation Energy’s Ginna nuclear reactor on the shores of Lake Ontario near Rochester, NY on Wednesday; the nuke remains down.

Staff reports for Democrat and Chronicle.com yesterday, No estimate on when Ginna nuclear plant will be back online,

The Ginna nuclear power plant in Wayne County remained shut down Friday afternoon, 48 hours after it went off line unexpectedly due to a generator problem.

No estimate was available of when the plant would go back into service, said Maria Hudson, spokeswoman for Constellation Energy Nuclear Group, the plant’s Baltimore-based owner.

“We’re continuing with our repairs,” she said.

The 581-megawatt plant on the Lake Ontario shoreline, the largest in the Rochester area, ceased producing electricity Wednesday afternoon when Continue reading →

Arkansas Nuclear 1 still down since fatal accident in March

Apparently we still don’t know why this happened:

At approximately 7:50am on Sunday, March 31, 2013, a 600-ton generator stator fell onto the turbine deck and then about 30 feet to the train bay floor as was being lifted out of the Unit 1 turbine building at the Arkansas Nuclear One plant. One worker was killed and four others injured when the load fell.

Dave Lochbaum wrote for Union of Concerned Scientists 18 June 2013, Fission Stories #139: Arkansas Nuclear One Fatal Event,

The NRC reviewed U.S. nuclear plant experience with lifting loads with cranes between 1968 and 2002. The NRC reported that about two load drops per year happened during this period with ten incidents causing deaths. The NRC’s review concluded that there had been only three very heavy load drops (defined as a load weighing more than 30 tons). ANO-1 makes four.

While accidents can also happen with wind turbines or even installing solar panels on rooftops, a single solar or wind accident doesn’t Continue reading →

Interactive charts: U.S. nuclear power reactors (NRC data)

Why are all these “dependable” baseload capacity nukes down so much? See for yourself in these interactive graphs of NRC Power Reactor Status. They’re in Google annotated timeline format, with all the zoom and pan features used by Google finance for stock charts. But these Reactor Status charts show seven years of daily NRC power percentage data. Want to see last month, six months, any 7 days, or some other period? Now you can, for all 104 reactors, including the ones recently removed by NRC from status because they’ve closed permanently.

You can view your own local reactors in any of 20 charts. Why so many graphs? Google annotated timeline charts apparently were meant for comparing a few stock prices, and don’t handle more than about seven curves well. But you can see things in these graphs that are hard to spot in NRC’s daily tables.

If missing docs sunk San Onofre, will Doosan document-forging sink Vogtle and Summer?

If documents can doom the San Onofre nuke and maybe the NRC Chair, how about forged Doosan documents and Plant Vogtle?

Matthew L. Wald wrote yesterday for The Caucus, Tussle Over Nuclear Plant Documents May Sink N.R.C. Appointment,

The botched repair job that doomed a California nuclear plant has created a political whirlpool that may be close to claiming another victim: the chairwoman of the Nuclear Regulatory Commission.

The issue is no longer the plant itself, San Onofre, which the majority owner, Southern California Edison, announced on June 7 it would permanently close. The problem now is that Senator Barbara Boxer, Democrat of California, who is chairwoman of the Senate Environment and Public Works Committee and a longtime critic of nuclear power, has been seeking documents from the Nuclear Regulatory Commission about Continue reading →

Farley 1 reactor tripped

Nuclear reactor Farley 1, about 125 miles from here tripped off its Reactor Coolant Pump Buses yesterday. They plan to get around to informing the press about it real soon now; they didn’t even tell the NRC until today. Maybe somebody would like to call Farley and ask what’s going on? “The Farley plant resident inspectors can be reached by calling 334-899-3386.” Maybe ask them what caused all those other downtimes at Farley over the years; maybe also about Browns Ferry and Hatch, where new Resident Inspector Phillip Niebaum previously worked. Southern Company CEO Thomas A. Fanning asked us to look at SO’s safety record.

UNIT 1 AUTOMATIC REACTOR TRIP DUE TO THE LOSS OF A START-UP TRANSFORMER

“This is a report of an automatic RPS actuation and automatic ESF actuation per 10CFR50.72(b)(2)(iv)(B) and 10CFR50.72(b)(3)(iv)(A). Additionally, this is to report intentions for a press release per 10CFR50.72(b)(2)(xi).

“At 2105 CDT on 6/11/13, Farley Unit 1 experienced an automatic reactor trip from 100% power. The initiating event was the loss of the 1B Start up Transformer which resulted in de-energization of the B-Train ESF 4KV buses and the 1B and 1C Reactor Coolant Pump Buses. The 1B Emergency Diesel Generator auto started and tied to the B-Train 4KV Emergency buses.

Korean nuke supplier for Plant Vogtle forged documentation for “a host of nuclear reactors”

Korea’s Doosan supplied that that train-wrecked Plant Vogtle reactor vessel later left unprotected sitting at Savannah port, as well as parts for more than a dozen U.S. reactors. And Doosan, according to the Korean government, forged documentation that just shut down “a host of nuclear reactors” in Korea, whose Prime Minister said,

“Those found to be involved in wrongdoing or corruption must be sternly punished by the law, regardless of their rank and status.”

According to World Nuclear News 5 June 2008, Doosan awarded further contract by Westinghouse, Continue reading →

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.
