Keep SanO Shut Down

San Onofre, my local nuclear reactor, is completely shut down right now (like all but one reactor in Japan) and may never reopen. Why not? Because the steam generator tubes (made in Japan, by the way) clang into each other. Why does that happen? Apparently because the plant tried to increase the power output of the reactor by adding nearly 400 extra tubes when they ordered a "like-for-like" replacement of the original (four) steam generators, which were supposed to last the entire lives of the (two) reactors.

The original steam generators didn't last because they ran 'em too hot, I suspect. A couple of years ago they realized that as soon as the tubes wear out, they can replace them with steam generators that have more tubes inside but still fit in the same locations. (Or thought they could.) So they upped the power output of the reactor, which caused the tubes to fail more quickly than the normal life of the reactor -- but they didn't care. They knew our California Public Utilities Commission would stick the ratepayers with the cost of the replacement steam generators when the time came -- and they did. SanO's owners wanted to avoid having the steam generator replacement happen at the same time as the much more risky license renewal because there's ALWAYS a lot of opposition to that.

San Onofre's owners got through several steps of this process. The Nuclear Regulatory Commission saw it as a "like for like" replacement even though it wasn't, the ratepayers were charged with the costs of replacement, it happened years before license renewal, and best of all (from the utility's point of view), the utility ALSO made billions of extra dollars while they ran the reactors at extra-high power, pressure, and temperature, blowing out the gaskets, seals, and tubes!

It's like how you treat a rented car.

Only the difference is, things can go wrong when steam generator tubes burst. They are very thin, fragile things, with a thousand pounds of pressure differential on one side from the other. One tube failure can lead to another, and another, and another, which can lead to an inability to cool the reactor. Fukushima USA. is what it could lead to!

Fundraising for 2nd Peaceful Protest at San Onofre on April 29

We are now fundraising for the April 29 2nd Peaceful Protest at San Onofre state park campground. We are bringing Professor Daniel Hirsch from San Cruz CA down as our keynote speaker. To raise this money we are selling T-shirts in black that say “San Onofre Our Fukushima?”. We will be selling these at the SD Earth Day event April 22, and at the Protest on April 29. To get one earlier send me a email at: genston(at)sbcglobal.net Your help is appreciated.

These 131I levels represent a significant input into the kelp forest ecosystem.

The Fukushima Daiichi Nuclear Plant, damaged by an earthquake and tsunami on March 11, 2011 released large amounts of 131I into the atmosphere, which was assimilated into canopy blades of Macrocystis pyrifera sampled from coastal California. The specific activity calculated to the estimated date of deposition/assimilation ranged from 0.6 to 2.5 Bq gdwt–1, levels greater than those measured from kelps from Japan and Canada prior to the release. These 131I levels represent a significant input into the kelp forest ecosystem. Canopy-forming kelps are a natural coastal dosimeter that can measure the exposure of the coastal environment to 131I and perhaps other radioisotopes released from nuclear accidents. An organizational mechanism should be in place to ensure that they are sampled immediately and continuously after such releases. (PDF)

Should we all have been taking Potassium iodide the weeks after Fukushima?

We Are All Radioactive Surfers

We Are All Radioactive an online crowdfunded episodic documentary about a group of surfers rallying to rebuild Japan after the March 2011 earthquake, tsunami and nuclear melt down in Fukushima.

And a cautionary tale for anyone living downwind from the aging San Onofre Nuke Plant.

SafeCast Crowdsourcing Global Radiation Levels

Hundreds of millions of smartphones have been sold worldwide. Radiation detectors and dosimeters that leverage the network capabilities of smartphones to measure and share radiological data have recently been launched in the market. In this paper we will analyze how crowd inspection – the collective measurement and sharing of radiological data by the general public – will potentially change emergency planning and response. The Fukushima Daiichi nuclear reactor tragedy in Japan spearheaded the acquisition of thousands radiation detectors and dosimeters by the general public. The perceived lack of communication from the Japanese government on the radiation levels in the country soon after the earthquake and tsunami that rendered the nuclear power station inoperable on March 11, 2011 led the general public to take their own radiation measurements. Initially, social media services were used to disseminate radiation levels in Japan. Just a few weeks after the disaster the first integration sites were created to collect and share measurements from individual radiation detectors. The second generation of fully networked and integrated radiation detectors have been introduced to the market recently. These devices allow users to seamlessly measure and share information using a smartphone or tablet. As the adoption of these devices increases, it is necessary to revisit emergency planning and response. These points must be taken in consideration.

First, the public must be educated on the correct use and interpretation of the results from these devices. Background radiation and seasonal variations must be carefully explained to avoid unnecessary confusion.

Second, emergency response plans have to be communicated with the general public.

For example, the San Onofre Nuclear Generating Station (SONGS) is located in a highly populated area in southern California. With almost 9,000,000 people living in a 50 miles radius from SONGS, it is important for authorities to have mitigation strategies to avoid mass chaos in case of an improbable radiological event. The concern is to have the public knowing about higher levels of radiation before authorities have a chance to plan a response. Conversely, crowd inspection can be used as a powerful instrument to help minimize the fears and concerns of the public residing near nuclear generating stations. The ability to measure and share actual radiation levels will minimize the impact that news reports have on every small incident that happens inside a nuclear power plant.

Crowd inspection is an inevitable technology evolutionary step. SafeCast.org

How will crowd inspection change the way we plan and respond to radiological emergencies?
