MANUAL REACTOR SCRAM DUE TO AN UNISOLABLE EXTRACTION STEAM SYSTEM LEAK
"At 0610 EST hours on January 25, 2011, Susquehanna Steam Electric Station Unit 1 reactor was manually scrammed due to an unisolable extraction steam system leak in the 1C Feed Water Heater Bay area.
"At 0517 EST reactor operators commenced lowering reactor power from 98.4% to 65%. Attempts to isolate the source of the leakage were unsuccessful. Based on continued indications of unisolated steam leakage, operations decided to shut down the plant. The reactor operator placed the mode switch in shutdown. All control rods inserted. Reactor water level lowered to -31 inches causing Level 3 (+ 13 inches) isolation and RCIC initiation. The operations crew subsequently maintained reactor water level at the normal operating band using FW [feedwater]. No steam relief valves opened. All safety systems operated as expected. RCIC automatically initiated on a -30 inch level signal and was manually secured.
"The reactor is currently stable in Mode 3. Investigation into the cause of the extraction steam system leakage is underway.
"The NRC Resident Inspector was notified. A voluntary notification to PEMA and press release will occur."
The steam leak was isolated after the turbine was tripped. The plant is stable at normal temperature and pressure. Decay heat is being removed via the condenser steam dumps to the main condenser. The electrical lineup is in a normal configuration. Estimated time to restart is not known.
From the Scranton Times Tribune:
The Susquehanna 1 nuclear power plant was manually shut down this morning due to a steam leak, according to the Nuclear Regulatory Commission.
The Susquehanna 2 power plant was not affected and continues to operate normally, the NRC said.
The shutdown came at 6:10 a.m., after operators decided steam from the boiling water reactor could not be contained "without impacting other systems," the NRC said. All plant safety systems operated as expected during the shutdown, the NRC said.
An NRC inspector was sent to the scene, and PPL Corp., which operates the power plant, is investigating the cause of the leak, the NRC said. No injuries or releases of radioactivity to the environment were reported.
From the Fairbanks Daily News-Miner:
Nuclear energy isn’t a good fit for Alaska right now but could be within a decade or two. If a new generation of small, user-friendly reactors hits the market, nuclear power could actually be a viable energy source for Fairbanks, according to a report coming soon by University of Alaska researchers. But it would take even higher energy prices and years of product testing and development before the chain reaction were initiated in Alaska.
“This has possible applications in Alaska, there’s no question about that,” said Gwen Holdmann, director of the UA Alaska Center for Energy and Power in Fairbanks. “But we have some time here.”
Nuclear energy doesn’t make sense now because current gigawatt-sized reactors are too big for Alaska’s power needs. But a renewed push for nuclear power by the federal government and industry could be clearing the way for new technology. Now smaller-scale, modular reactors are approaching the permitting process that could redefine the look and usefulness of nuclear power.

We would like to invite you all to come out and participate with us on any of these events for a step, a day or the whole event. Please call 513-843-1205 or visit our website for information about how to participate.
What can you do to help?
- Plan an overnight for us; we don't require much just a place to put down a bedroll and restrooms. Schedules are on the website.
- Help organize a pot luck dinner and a meeting with the community.
- Help distribute information on the event and about FootPrints for Peace.
- Also please consider making a modest donation by writing a check to FootPrints for Peace (in the memo write which event you would like to donate to) and sending it to 1225 North Bend Rd, Cincinnati, Ohio 45224, USA.
- Or by making a credit card donation through PayPal
Hope to see you on the road.
Peace and love,
Jim, Larry, Jon, KA, and Marcus

From Fake Rob Williams:
It's so cool. You know, one of the things that people don't really appreciate about Vermont Yankee is how much fun we have around here forgiving each other for our blunders and mistakes. It's really a "peace, man" and "no worries" kind of place. Another very cool fact about us: Our employees are happy, picturesque people with good singing voices.
From the Philadelphia Inquirer:
A state law designed to shield people from lawsuits when they try to protect the environment suffered a blow Wednesday when the state Supreme Court ruled in a long-running case involving a Chester County development.
The court ruled, in part, that the Environmental Immunity Act does not shield parties who may have already reached a court-approved agreement on an issue.
"It looks like, environmentally, we took one on the chin," said State Rep. Camille "Bud" George (D., Clearfield), who led the effort to pass the Environmental Immunity Act in 2001.
A study released by the Environmental Law Institute, a nonpartisan research and policy organization, shows that the federal government has provided substantially larger subsidies to fossil fuels than to renewables. Subsidies to fossil fuels totaled approxi- mately $72 billion over the seven-year study period, while subsidies for renewable fuels totaled $29 billion over the same period. The vast majority of subsidies support energy sources that emit high levels of greenhouse gases when used as fuel. Moreover,
just a handful of tax breaks make up the largest portion of subsidies for fossil fuels, with the most significant of these, the Foreign Tax Credit, supporting the overseas production of oil. More than half of the subsidies for renewables are attributable to corn-based ethanol, the use of which, while decreasing American reliance on foreign oil, has generated concern about climate effects.These figures raise the question of whether scarce government funds might be better allocated to move the United States towards a low-carbon economy.
From the New York Times:
Described simply, “Radioactive” is an illustrated biography of Marie Curie, the Polish-born French physicist famous for her work on radioactivity — she was the first person to win the Nobel Prize twice — and her equally accomplished husband, Pierre. It lays bare their childhoods, their headlong love story, their scientific collaboration and the way their toxic discoveries, which included radium and polonium, poisoned them in slow motion.
Described less simply, it’s a deeply unusual and forceful thing to have in your hands. Ms. Redniss’s text is long, literate and supple. She catches Marie Curie’s “delicate and grave” manner as a young student, new to Paris; she notes the “luminous goulash” of radium and zinc that one chemist prepares; she observes with pleasure another man’s “thriving mustache.” She has a firm command of, but an easy way with, the written word.
The electricity in “Radioactive,” however, derives from the friction between Ms. Redniss’s text and her ambitious and spooky art. Her text runs across and over these freewheeling pages, the boundaries between word and image constantly blurring. Her drawings are both vivid and ethereal. Her people have elongated faces and pale forms; they’re etiolated Modiglianis. They populate a Paris that’s become a dream city.
Plans to build underwater civilian nuclear reactors are in the works in France, with a prototype expected to be rolled out in 2016, officials said.
DCNS, the French state-controlled naval company, said it will work in partnership with French companies Areva, EDF, and the French Atomic Energy Commission to build small- and medium-sized underwater reactors to provide electricity to consumers on land, Radio France Internationale reported Wednesday.
The company said its Flexblue project, expected to enter the building phase in 2013, is in response to global energy challenges and renewed interest in nuclear power.
FirstEnergy Corp. reported to federal regulators today that a small electrical fire erupted overnight at the Davis-Besse nuclear power plant near Toledo.
An apparent short about 2:30 a.m. in 480-volt temporary power cable running on the ground to a building under construction sparked the blaze in plastic and rubber material covering the cable.
A plant fire brigade put the fire out in 10 minutes, using two dry powder fire extinguishers. There were no injuries and operations at the power plant were not disrupted.
"We are investigating the cause and will be meeting with the contractor," said Todd Schneider, company spokesman.
