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).

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.

Harris 1 7% last 27.41% for the month

Nuclear reactor percent power from NRC data

Do nuclear reactors really deliver dependable baseload capacity? I hear industry execs say 99.99% uptime. The real average from seven years of NRC data for 104 reactors is 88.13%.

Vogtle 1 According to Power Reactor Status Reports posted online by the Nuclear Regulatory Commission, here are the actual percent power percentages over time for the 104 listed nuclear power reactors. The timeframe is 31 March 2006 through today, 21 May 2013. (The NRC data appears to go back to 1999, but seven years is a good sample to start with.) The computation for each reactor is the sum of the uptime percentages for each day divided by the number of days. The total uptime is the sum of the reactor uptimes divided by the number of reactors. Here’s the list, sorted two ways:

No San Onofre nuke startup decision until June at least –NRC Chair

Two more victories for anti-nuke activists: San Onofre restart decision pushed back at least until June, and webcasts of California Public Utilities Commission hearings going on right now.

Abby Sewell reported for the L.A. Times yesterday, Decision on San Onofre pushed back to June at the earliest,

The plant’s operator Southern California Edison had hoped at one point to have one of the plant’s two units operating by summer, but NRC Chairwoman Allison Macfarlane made it clear that will not happen.

Macfarlane told reporters Tuesday after a speech, “You know, the process is very complicated now. Almost every day it gets a little more complicated…. Right now I can tell you a decision on restart won’t happen until the end of June, certainly after the middle of June.

“It may get pushed back later,” she said. “I don’t know.”

She didn’t say much about the Atomic Safety and Licensing Board (ASLB) decision to require NRC public hearings before any decision on restarting San Onofre, but she did say this:

NRC tries to ignore hearing requirement for San Onofre nuke restart

Maybe the ASLB was referring to some other NRC that should hold public hearings? The Atomic Safety and Licensing Board (ASLB) agreed with Friends of the Earth (FOE) when it ruled that restarting either San Onofre unit requires a full public hearing like a trial, but the Nuclear Regulatory Commission (NRC) interprets that as having nothing to do with its own staff decision process. This is after the city of Los Angeles (and numerous other southern California cities and the San Diego Unified School District) said it didn’t want any decision about restarting any San Onofre reactor/ without a full, transparent, public decision process. The L.A. Times says all this is creating “confusion”. Just last week I heard Georgia Power CEO Paul Bowers say confusion was bad for business. Maybe it will be bad not just for Southern California Edison and its San Onofre nukes, but also for Georgia Power and Southern Company’s 19-month-late and billion-over-budget nuclear boondoggle at Plant Vogtle.

Two former national nuclear regulatory chiefs: stop nukes

Last month former U.S. Nuclear Regulatory Commission Chair Jaczko said all 104 operating U.S. nuclear power reactors are unsafe. This month former Indian Atomic Energy Regulatory Board Chair Gopalakrishnan says the reactors currently building in India, already three years behind schedule and now found to incorporate numerous defects and deficiencies amid gross lack of transparency, must be stopped. When will the NRC stop the restart of the flawed and non-transparent San Onofre 2? When will the NRC or GA PSC or the GA legislature or even Southern Company coming to its senses stop the 19-month-late $1-billion-overbudget flawed-concrete Plant Vogtle 3 and 4 before they waste any more of our resources that could be going to solar and wind jobs and energy?

Believe So. Cal. Edison about San Onofre?

Should we believe the operator of the broken San Onofre 2 nuclear plant that it’s safe to restart at 70% power? The same operator that knew the now-broken steam generators were flawed before it installed them? Recommended by the same NRC staff who couldn’t answer opponents’ questions? The same NRC that doesn’t publish licensee documents and says that’s never been a practice?

SanDiego6.com wrote yesterday, Sen. Boxer Blasts Report on San Onofre Nuclear Generating Station,

On Monday, Southern California Edison announced it had formalized a request to amend its operating license to allow it to operate its Unit 2 reactor at 70 percent beginning June 1.

The reactor was undergoing scheduled maintenance in January 2012 when a small, non-injury leak was discovered in plant’s other reactor. The plant has been shut down since.

According to Edison, vibrations that led to premature wearing of steam pressure tubes in the reactors don’t occur at 70 percent power. The utility wants to operate on limited power for the five warm weather months and then shut down for an inspection of the tubes.

After the inspection, the reactor would resume operating at 70 percent power. The company said it would use the collected tube data to determine an appropriate power setting for the long term.

There’s the catch:

Even the smallest amount of tritium can have negative health impacts, and most nukes leak tritium.
