Test program meeting at Plant Vogtle –NRC and Southern Company 9 October 2013

Safety at Plant Vogtle, this Wednesday, with call-in number, by NRC and Georgia Power’s parent the Southern Company. One hour from 1 to 2PM is the public part, then 3 more hours closed “because the staff has determined that the information is proprietary in nature.” Why is nuclear testing affecting public safety proprietary?

It’s at Vogtle Training Center, 9034 River Road, Waynesboro, GA 30830, which is on the corner of the Plant Vogtle site. Do you get a tour of the construction if you appear in person? Here’s what it looks like in Georgia Power’s Vogtle 3 and 4 Construction Photos September 2013, and on google maps:

Potential defects shipped to Farley reactors and four others

No worries about this reactor coolant system defect; Westinghouse says so, and didn’t even list Vogtle or Diablo Canyon, where Southern Company and PG&E said they were going to install these shields. Nevermind a reactor operator warned us back in January. Westinghouse did list “Beaver Valley Unit 2, Callaway, D.C. Cook Unit 1, Farley Units 1 and 2, and Wolf Creek”.

NRC Event Notification Report for July 29, 2013 Event Number 49217:

POTENTIAL EXISTENCE OF DEFECTS IN SHIELD PASSIVE THERMAL SHUTDOWN SEAL SYSTEM

“The defect being reported concerns an identified inconsistency between the intended design functionality of the SHIELD passive thermal shutdown seal (SDS) and that observed during post-service testing.

“The purpose of the SDS is to reduce current reactor coolant system inventory losses to very small leakage rates for a plant that results in the loss of all reactor coolant pump (RCP) seal cooling. The SDS is a 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).

1 month Farley 1 nuclear reactor status percent power “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.

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

Activists Grill NRC on San Onofre Restart

Ecological Options Network (EON) posted video of public comments at the latest Nuclear Regulatory Commission (NRC) meeting about restarting San Onofre 2, where documents indicate Southern California Edison knew the new steam generators were defective years before they even installed them.

EON noted:
In these video excerpts from the 4-3-2013 NRC webcast, informed activists hammer the NRC staff and SoCal Edison reps with penetrating comments and questions about apparently collusive fast-track plans to restart one of San Onofre’s broken reactors—in a tsunami and earthquake zone, in the middle of a strategic U.S. military base, in a surrounding urban area with a population of 8.5 million people—a plant that is not cost-effective 99% of the time, operated by a utility with the worst safety record in the country.

What could possibly go wrong?

Participants include Ace Hoffman, David Freeman, Kendra Ulrich, Dan Hirsch, John Geesman, Ray Lutz, Gary Headrick and Myla Reson.

Activists just helped convince NRC to deny a license for Calvert Cliffs 3 in Maryland, and Continue reading →

Fukushima still broken 2 years after

Tomorrow is the second anniversary of the earthquake and tsunami that heavily damaged four of the six nuclear reactors at Fukushima Dai-ichi in Japan on 11 March 2011, also known as 3/11. The broken reactors at Fukushima continue to leak radioactive substances into groundwater, the sea, and the air, where it is carried across oceans to the U.S. and elsewhere. And it could still get much worse: if the No. 4 reactor pool, still suspended in the air, collapses and causes the disintegration of spent fuel rods from all the other reactors there, Tokyo, 200 miles away, will have to be evacuated. Fukushima’s GE reactors are the same GE Mark I design as Southern Company’s Plant Hatch 1 and 2 only 100 miles from here at Baxley, GA, and about 200 miles from Atlanta and Charleston. Hatch is leaking radioactive tritium into our groundwater again. Five more reactors within 500 miles of here are also GE Mark I.

Among the 311 or so facebook pages and websites about Fukushima or against nuclear power is this concise one, Unplug Nuclear Power, which offers a simple action anyone can take tomorrow:

On 3/11, we will mark Fukushima day by using as little utility supplied electricity as possible. This direct Action is designed to punish the utility companies for continuing to push for nuclear power even after the Fukushima disaster has proven that it is just too dangerous. On that day, we will punish them in the only way that they understand, by denying them our money. There will be four levels of participation, go to the website, www.unplugnuclearpower.com for a more complete description. Also, be sure to join the Event. Finally, if you are in a group our organization that can endorse this Action, please let us know.

As Jeremy Rifkin so concisely spelled out, nuclear power is over Continue reading →

SC Edison knew San Onofre nuke steam generators were flawed before installation

Southern California Edison knew the new steam generators were defective years before then even installed them in the San Onofre nuclear reactors, acccording to a report just released. These are the generators that failed and caused both San Onofre reactors to shut down. SD Edison wants to restart one of them, and this document came out in that process. Southern Company would never do this, right? We shouldn’t worry about failed concrete or 15, no now 19, months delay while the Georgia legislature won’t even limit charges to Georgia Power customers for cost overruns. Nope, no worries.

Friends of the Earth PR 8 March 2013, San Onofre: Secret Report Confirms Edison Knew of Major Problems; Friends of the Earth: ‘Bombshell’ for plans to restart crippled reactor

WASHINGTON—March 8—A secret Mitsubishi Heavy Industries report released today confirms that Southern California Edison knew about serious problems in the radically redesigned replacement steam generators for the San Onofre nuclear reactors years before the defective equipment was installed, yet failed to make changes to fix the problems. The report was released today by the Nuclear Regulatory Commission after Senator Barbara Boxer (D-Calif.) and Representative Edward Markey (D-Mass.) revealed its existence and demanded it be made public.

Low and Down Recent NRC Reactor Status

Twenty seven of 104 NRC status reactors are below 100%, and 15 are at zero power. What happened to supposedly 24/7 nuclear power?

Low Recent NRC Reactor Status

Fifteen are at zero power: Calvert Cliffs 2, Crystal River 3, Diablo Canyon 2, Fort Calhoun, Hatch 1, Hatch 2, La Salle 2, McGuire 1, River Bend 1, San Onofre 2, San Onofre 3, South Texas 2, Turkey Point 3, Turkey Point 4, and Wolf Creek 1. (Seventeen if you count never-started Vogtle 3 and Vogtle 4.)

Sure some of these are down for good (Crystal River 3) and others have been down for a year or more (San Onofre 2 and 3). But

Hatch 1 nuclear reactor down to 40% power Sunday: why?

Why is Plant Hatch Unit 1 running at well below capacity? Saturday 19 Jan 2013 that nuclear plant was at 100%, according to the NRC, yet Sunday it was down to 45%, then 40% Monday and 64% today. What's going on at Hatch 1? And what happened to nuclear supposedly being 24/7?

There's no event report about this from the NRC; the last item the NRC has on Hatch 1 seems to be from 2003. Southern Company provides no information on this event. Another source (Platts, 4 January 2013) says Hatch 2 (and Vogtle 2) are to refuel in the first half of this year, among Fifty-six US nuclear units to shut for refueling in 2013. But Hatch 1 is not on that list, and a similar Hatch 1 brownout happened 5 and 6 January:

Shutdown at San Onofre: permanent this time?

California only has a couple of nuclear reactor locations (unlike the 32 reactors within 500 miles of here), and one is in even worse shape than the other: San Onofre, almost as bad as Crystal River. I’m sure Southern Company would never cut corners or have design or construction problems at Plant Vogtle, right?

Harvey Wasserman wrote for AlterNet 7 January 2013, Showdown at San Onofre: Why the Nuclear Industry May Be Dealt a Big Blow,

Perched on an ocean cliff between Los Angeles and San Diego, the reactors’ owners cut unconscionable corners in replacing their multi-million-dollar steam generators. According to Russell Hoffman, one of California’s leading experts on San Onofre, inferior metals and major design failures turned what was meant to be an upgrade into an utter fiasco.

Installed by Mitsubishi, the generators simply did not work. When they were shut nearly a year ago, tubes were leaking, banging together and overall rendering further operations impossible.

Southern California Edison and San Diego Gas & Electric have unofficially thrown in the towel on Unit 3. But they’re lobbying hard to get at least Unit 2 back up and running. Their technical problems are so serious that they’ve asked the Nuclear Regulatory Commission to let them run Unit 2 at 70% capacity. In essence, they want to “see what happens” without daring to take the reactor to full power.

The NRC has expressed serious doubts. On December 26 it demanded answers to more than 30 questions about the plant’s technical realities. There have been assertions that unless San Onofre can be shown as operable at full power, its license should be negated.

It’s good the NRC got around to doing something, after Continue reading →
