Address (RE: Fukushima Status) to GSB event (edits 5/19/2013)

5/19/2013: GE says: See Mitsubishi

3/9/2013 After attending a conference on the 2nd anniversary of the Fukushima meltdowns, I am editing video from the conference and waiting for my computer to save the large file(s), I would like to clarify that the diagrams I have offered to date for this situation focus on temporary measures to keep the structures in place until the fuel rods can be relocated. These diagrams do not involve “filling the buildings with gravel or foam” as one audience member suggested. They instead show sub-foundation transfer beams and an external foam auxiliary heat sink, should the fuel rods breach the containment vessel.

I’m David Curtis, I’m running for CA Secretary of State in 2014 as a Green Party candidate. The SOS is uniquely positioned to deal with statewide business issues, they also oversee the elections and political reform.

The current SOS, Debra Bowen is term limited.

Californians voted to have an open primary, the top two vote getters continue to the general election. I am hoping to be one of those two candidates.

A year ago when the accidents at the nuclear power plants at  Fukushima, Japan occurred, I assumed there to be industry people who are on top of the situation and I focused on other issues.

Then last month, news reports about radiation in the sea kelp off California coastline caused me to check in with Fukushima to see what progress had been made. To my surprise, the situation was not only unresolved, but was experiencing multiple set backs.

I spent a sleepless week thinking about the situation, and began diagramming potential fixes to stabilize the plants, this with no formal training in nuclear engineering, but with 24 years of design experience in architecture.

From what I can tell as an outside, independent designer, the Japanese have done several things to stabilize the plants, they installed shoring under the fuel rod storage pool(s), which remain vulnerable due to the original design and siting of the plants. The plants were not designed to fully withstand the natural disasters that hit them and they remain suspended precariously if further major earthquakes occur. From public information, there are now large cranes on site, likely to remove portions of the damaged containment buildings. The Japanese posted photo(s) of a steel crown device that I guess will (lift something or) attach to the fuel rod assemblies so they can be transferred to the cooling pools since the original bridge cranes were destroyed in the explosions last year.

The PM of Japan  publicly stated the nuclear plants will be decommissioned. All of the plants are currently in shut-down modes. This is if the public information is to be believed.

I designed a mediation device that would serve as a temporary seismic retrofit. I sent it to the Japanese PM last month. I also copied GE the original designers of the plants, the Army corps of engineers and president Obama. I did this design for free and put it into the public domain for peer review. I asked ARUP SF to peer review it also.

I sent a bill to GE for $5000, they have a standing offer on their website for ideas.

You can see the mediation device on my portfolio on archinect. I also have copies here with me if you would like one.

The reason this is relevant to California is there were large releases of radioactive material and water into the pacific ocean. I do not know the extent of these releases. Democracy Now claims the releases are now thought to be 2.5 times what was originally published. I do not know the current rate of releases. The dosage to the ocean seems to be concentrated between the east of Japan and west of Hawaii. (portion deleted)

Until more is known, I personally am avoiding seafood until I know better.

I am also concerned with the short and longterm effects to agriculture and seafood in Hawaii, California, Oregon and Washington state.

I am hoping the Japanese government will be as transparent as possible during the continued work there. I am also recommending that all nuclear plants in the US that are in high seismic activity zones be decommissioned.

I am advocating that California transition to 100% organic farming as quickly as possible.

I’ve outlined a process for doing this on my campaign website.

(but) We are a global community. We cannot fully transition to organics in California without addressing the toxicity that comes from factory farming and the radiation that we are inheriting now from Fukushima, and other domestic nuclear plants sited similar to those in Fukushima.

I made an initial visit to UC Berkeley Nuclear Engineering Dept yesterday, but did not make contact with any of the professors there.

Fukushima Enclosure Proposal 2

“I cannot advocate for organic farming in California without addressing the events in Fukushima” -David Curtis


Concept sketch: EPS Form Blocks with lead facing.
Levy to stop aquifer migration. Water pump.

I am recommending in addition to whatever “road map” the operators of the facility issued December 2011, they consider the following.

Redundant levy construction per above sketch.

Temporary building wraps with lead impregnated tyvek or equal.

Redundant enclosure offset some distance from the existing structures with provisions for blast release. DC 4/13/2012

Last year, an industry person was quoted as guessing that if there are full melt downs the material would likely collect in the concrete containment vessel floor rather than breech it.

It seems there is a need for three redundant systems:

1. A method to contain the releases that occur/occurred into the underground aquifer.

2. A method to prevent releases to the adjacent ocean.

3. A redundant enclosure to prevent atmospheric releases.

4. Redundant cooling systems.

5. Once the systems are sufficiently cooled can the fuel rods be transferred to casks similar to ones proposed for the now cancelled long term storage facility in the US? edits 4/13/2012 dc
