Repost of a great letter to the NRC:

Dear Mr. Collins,
I was told recently that "no one" in the legislature of California believes San Onofre Unit III can be restarted unless/until its steam generators are replaced. To this I replied, "No one else thinks so either."
I believe all this talk about Unit II restarting should be stopped cold as well because, in fact, neither unit is capable of being safely restarted, where "safely" is defined by standard nuclear industry benchmarks.
I believe the potential for the complete loss of a single Steam Generator in a two-steam-generator system with weakened tubing is utterly unacceptable. But that's the possible condition any restart of San Onofre's reactors leaves us in. In fact, at San Onofre it's almost the most likely point of failure, except for fire (with earthquakes, tsunamis, etc. also distinct possibilities).
I believe Southern California Edison cannot merely put flow restrictors on the inlets to the Steam Generators in order to guarantee that excessive, vibration-inducing flow cannot occur, because then they won't have enough maximum potential flow rate to cool the reactor sufficiently with only the other Steam Generator, should one Steam Generator fail. But without the flow restrictors, a flow rate would be possible above that which ensures that there is little or no flow-induced turbulence (a chaotic flow pattern), and NO chance of fluid elastic instability (a coordinated flow pattern).
I believe the reason SCE hasn't been able to come back to the NRC with a plan for restart as of this writing is that they can't find the magic "sweet spot" where the flow is restricted, but they could still cool the reactor sufficiently in an emergency with just one Steam Generator. I don't think such a combination of guaranteed low enough flow rates and guaranteed sufficient emergency cooling can be found.
They may also be having a difficulty ensuring there are not similar flow-induced vibration problems within the reactor core itself, since a whistleblower, Dan Johnson, has been adamant in the news media comments section that such vibrations have been a persistent problem at SanO since Unit I.
The difficulty of finding this "sweet (and profitable) spot" and other problems caused by SCE's failure to properly analyze their data during the design phase, their failure to properly inform both the NRC and the public about the extensive nature of the SG design changes, and the NRC's failure to independently analyze the new steam generator design has led to this billion-dollar boondoggle.

The Energy SYSTEM itself is keeping the US and especially California from going Solar (of all flavors) much quicker...
Many, many more would install Solar if the Utilities paid those that installed Solar for the energy they put INTO the grid, at the very same rate that the Utility charges for that same Energy to folks that take Energy OUT of the Grid! By not paying the same amount, the Utility shareholders receive additional money they do not deserve and the folks that have installed solar end up with a much longer payback period! You can be sure if these Utilities operate their own Solar Farms, they will pay themselves every penny they can...
Remember Solar usually adds Energy during peak period of use (daytime) and it is only fair that if the Utility charges more for Energy used during that period (by using Smart meters) then they should also credit that exact amount to those with Solar that add Energy during those periods!
Remember we all already pay an additional fee for maintaining the Grid itself, so this rate ripoff is nothing but a Utility "Profit" Scam...
Hello CPUC ===> It is WAY PAST TIME to STOP THE SOLAR ENERGY RIPOFF!
Why should shareholders get record profits while the only thing rate payers get is ever increasing bills?

New “Bike Corral” for North Park
Ciclovia: Bogotá, Colombia by Clarence Eckerson, Jr. on December 1, 2007 | 201,437 Plays SNIP: Recently, I had the opportunity to travel with comrades Karla Quintero (Transportation Alternatives) and Aaron Naparstek (Streetsblog) to Bogotá, Colombia to document some of the amazing advances going on in the livable streets movement there. On Sunday we spent the entire day - from 5 AM 'til nearly 5 PM - riding bicycles around the city courtesy of the Ciclovia, a weekly event in which over 70 miles of city streets are closed to traffic where residents come out to walk, bike, run, skate, recreate, picnic, and talk with family, neighbors & strangers...it is simply one of the most moving experiences I have had in my entire life. This should be easy to do in SD! http://www.streetfilms.org/ciclovia/— September 10, 2012 4:25 p.m.
New “Bike Corral” for North Park
Maybe NP will help the City of SD do something like this: BMW Guggenheim Lab Create ‘Dynamic Connections’: A Crowd-Sourced Cycle Map for Berlin Cyclists [http://inhabitat.com/?p=434758][1] snip The problem with cycling in a big city is that many maps are outdated, and certain routes aren’t exactly ‘cyclist-safe’. With this in mind, BMW Guggenheim Lab and Lab City Project have created ‘Dynamic Connections’ – a crowd-sourced bike map of information for cyclists in Berlin. The map was created for German cyclists in order to “enable cyclists to mark the routes they frequently ride on a Google-based map”. Users are also able to answer a number of questions about that route regarding traffic flow, number of parked cars, visibility, topography, and the density of amenities along the route.

San Diego had surplus power even during recent heat wave
Cont: The solution is to withdraw SCE's license. It should be noted that they also do not have a solution to their ever-growing used reactor core waste problem, and nor does the NRC. Our coastline is too precious and too packed with people for dry cask storage, wet storage, or any storage of nuclear waste. So shut down San Onofre permanently. The production of waste has stopped -- thank goodness -- and it should never continue. Restarting also violates the spirit of California's state law that prohibits "new" reactors because what is a reactor core except a new reactor every couple of years? I look forward to hearing the NRC response to these concerns. Sincerely, Ace Hoffman Carlsbad, CA— August 24, 2012 1:42 p.m.
