Nuclear Power

Nuclear power cannot address climate change effectively or in time. Reactors have long, unpredictable construction times are expensive - at least $12 billion or higher per reactor. Furthermore, reactors are sitting-duck targets vulnerable to attack and routinely release - as well as leak - radioactivity. There is so solution to the problem of radioactive waste.

NRC has rubber-stamped license extensions and "power uprates" at 22 of 23 GE BWR Mark I reactors operating in the U.S.

Pat Birnie of the GE Shareholders Alliance has compiled U.S. Nuclear Regulatory Commission (NRC) data on "power uprates" which the agency has approved at 22 of the 23 General Electric boiling water reactors of the Mark I design still operating across the U.S. (Nine Mile Point Unit 1 in NY is the only exception). Her chart is accessible here. The Fukushima Daiichi Units 1 to 4 which exploded and melted down beginning in March 2011 are also GE BWR Mark Is.

The single biggest power uprate, as a percentage of heat output (measured as Megawatts-thermal, or MWt), was a 20% "extended" type power uprate, granted in 2006 to Entergy Nuclear at its 34 year old (at the time) Vermont Yankee atomic reactor. This amounted to a 319 MWt power uprate (MWt must be divided by three to determine the Megawatts-electric, MWe, generated, due to the fact that 2/3rds of the heat generated by splitting atoms is lost as waste). The vibrational stresses caused by Vermont Yankee's power uprate led to the collapse of its cooling tower (see photo at left), and even contributed to a separate fiery explosion, when the increased pressure of flowing steam picked up loose metallic slag that had lain dormant for decades and slammed it into an operational transformer.

However, even bigger power uprates have been rubberstamped by NRC. The single biggest, at an individual Mark I reactor, was the 547 MWt of power uprates, granted in two installments (one a "Measurement Uncertainty Recapture" type uprate), at the Hope Creek, New Jersey Mark I. However, both Brunswick Mark Is, Units #1 and #2 in North Carolina, have each enjoyed a total of 487 MWt of power uprates, including a "stretch" type uprate, for a whopping 974 MWt of power uprates at the Brunswick nuclear power plant.

NRC gave the newly formed Exelon Nuclear Corporation (formed by the merger of Commonwealth Edison of Chicago and Philadelphia Electric Company, the first and second largest nuclear utilities in the U.S.) an early Christmas gift in 2001: a 17.8% power uprate at both of its Quad Cities 1 & 2 Mark Is, worth 446 MWt each; and a 17% power uprate, worth 430 MWt, at each of its Dresden 2 & 3 Mark Is. All four approvals took place on a single day, December 21, 2001. The combined power uprates at the four Mark I reactors netted Exelon 1,752 MWt of additional output.

While the nuclear utilities enjoy increased profits from the additional electricity sales associated with power uprates, the public downwind and downstream bears the risks of running these Mark Is harder and hotter than they were originally licensed or designed for. To make safety risks even worse, 22 of the 23 operating Mark Is have already received NRC rubberstamps for 20 year license extensions; Fermi 2 is the only exception, and it plans to apply for one in 2014. Pat Birnie has also compiled a listing of the 23 operating Mark Is in the U.S., including the reactor units' names, locations, expiration dates for their original 40 year licenses, and expiration dates for their NRC-authorized 20 year license extensions.

Pat Birnie has succeeded in getting an anti-nuclear shareholder resolution, written in the aftermath of the Fukushima Nuclear Catastrophe, onto the agenda of the General Electric annual shareholders meeting, to be held in downtown Detroit on April 25th.

NRC violates its own environmental protection mandate: 5 Commissioners reject renewables alternative at Davis-Besse atomic reactor

Davis-Besse, located in Oak Harbor, OH along the Lake Erie shorelineOn the eve of the 33rd annual commemoration of the Three Mile Island meltdown, the five NRC Commissioners voted unanimously yesterday to reject an environmental coalition's contention that wind power and solar power could readily replace the 908 Megawatts-electric from Davis-Besse, instead of FirstEnergy's proposed 20 year license extension at the problem-plagued atomic reactor with a cracked concrete containment. The environmental coalition put out a media release, and plans to appeal to the federal courts at the first opportunity.

NRC's Atomic Safety (sic) and Licensing Board (ASLB) presiding over the Davis-Besse license extension proceeding has ordered pre-hearing oral arguments about the latest, cracked concrete containment contention. The oral arguments will take place on Friday, May 18th, beginning at 9 a.m. in the Common Pleas Courtroom at the Ottawa County Courthouse, 315 Madison Street, Port Clinton, Ohio -- about ten miles from Davis-Besse.

Nuclear Power's Green Mountain Grassroots Demise

In the wake of Fukushima, grassroots citizen action is shutting the worldwide nuclear power industry.

A Solartopian tipping point is upon us in the US, Europe and Japan which will re-define how the human race gets its energy.

States rights and local democracy are at the core of the battle.

The definitive breaking point looms in Vermont.

By mid-March a state board is likely to deny the Yankee reactor licenses to operate or to create radioactive waste. by Harvey Wasserman at Nukefree.org.

U.S. Congressman Conyers honors Beyond Nuclear at Fukushima commemoration

U.S. Congressman John Conyers (D-MI), ranking member of the U.S. House Judiciary Committee, one of the longest serving Members of Congress in U.S. historyU.S. Congressman John Conyers, Jr. (pictured, left), one of the longest serving members of Congress in U.S. history, and ranking Democrat on the U.S. House Judiciary Committee, honored Beyond Nuclear not only with his presence, but also his kind words, at a March 11th Fukushima Nuclear Catastrophe commemorative event held in Livonia, Michigan, near the Fermi 2 atomic reactor, the world's largest Fukushima Daiichi twin design reactor, a General Electric Boiling Water Reactor with a Mark I containment.

The event, "Will Fermi 3 Radiation 'Into Eternity?'," featured a screening of the documentary film Into Eternity, about Finland's proposed high-level radioactive waste dumpsite. Beyond Nuclear's Kevin Kamps followed the film with a presentation on the radioactive waste and atomic reactor risks plaguing the Detroit area, as well as the Great Lakes region beyond.

Congressman Conyers spoke first during the discussion afterwards, stating that this powerful event marked a turning point for anti-nuclear activism in the area. He said the event was one of the most important he had attended in some time, and that he would look into conducting congressional hearings on such important subject matter in the near future.

The event was organized by BetterWorld Happenings, founded by Keith Gunter, a Beyond Nuclear launch partner. About 80 people attended, including a number of long-time veteran anti-nuclear campaigners in Michigan representing Citizens for Alternatives to Chemical Contamination, Peace Action of Michigan, Don't Waste Michigan, Sierra Club Michigan Chapter Southeast Michigan Group, Coalition for a Nuclear-Free Great Lakes, and other organizations.

Update on defending Great Lakes against risky atomic reactors

Three weeks ago, we reported on Beyond Nuclear's efforts, in conjunction with environmental coalitions and concerned citizens, to shut down two especially risky atomic reactors on the Great Lakes shorelines that have been generating a lot of controversy recently: Palisades in southwest Michigan, and Davis-Besse in northwest Ohio.

A lot has happened since. NRC was forced to admit that Palisades has the most embrittled reactor pressure vessel in the U.S. NRC's repeated regulatory rollbacks have put it at risk of fracturing like a hot glass under cold water due to Pressurized Thermal Shock. And thanks to revelations by Congressman Dennis Kucinich, we've contended that Davis-Besse's containment cracking is so severe that its outer layer of steel reinforcement rebar is no longer performing its safety function. We joined Congressman Kucinich in challenging Davis-Besse's root cause report, which blames the cracking on the Blizzard of 1978, as a "snow job of convenience." Read more.
