Even as the Japanese attempt increasingly frantic tactics to cool an overheated nuclear complex:  

  • U.S. officials warned the situation is deteriorating and challenged the Japanese government’s assessment of the radiation risks telling U.S. civilians and military personnel to stay at least 50 miles from the facility, in contrast to the 12-mile evacuation zone set by Japan.
  • The Nuclear Regulatory Commission Chairman Gregory Jaczko told lawmakers that the U.S. believed the damage at the Fukushima Daiichi nuclear power complex was even graver than Japanese officials had outlined in public; and
  • U.S. Energy Secretary Steven Chu told those same lawmakers that he believed a “partial meltdown” had occurred at the Japanese nuclear power plant and that the accident was “more serious” than the 1979 partial core meltdown at Three Mile Island in Pennsylvania.

In the meantime, Jonathan Silver, executive director of the Energy Department’s loan guarantee program affirmed that it will continue to finance nuclear projects in the United States during a presentation he made today at the Cleantech Forum conference in San Francisco.

Mr. Silver’s remarks followed Congressional testimony in Washington by Energy Secretary Steven Chu and Gregory B. Jaczko, chairman of the Nuclear Regulatory Commission. In the same testimony that cautioned the situation at the Fukushima Dai-ichi plant was more serious than Japanese officials were saying,  Dr. Chu said that the Obama administration continued to support nuclear energy, noting the president had requested that $36 billion be appropriated for the nuclear loan guarantee program.

The loan guarantee program has come under fire from all sides, with Congressional Republicans, questioning whether the department has spent its money wisely and moving to cut funding for the $71 billion program.

An audit released last week by the Energy Department’s inspector general found that poor record-keeping made it difficult to evaluate some loan decisions.  This is especially concerning when considering the high capital cost and high default rate of nuclear projects both here at home and internationally.

NRG’s South Texas Project (STP) proposed expansion near Bay City, TX is high on the list of projects being considered for a federal loan guarantee under this program.  Many of NRG’s financial partners on this project, Toshiba, Tepco (the operators of the doomed Fukushima Dai-ichi plant) and the Japanese government (through loan guarantees)  are probably looking at considerable contraints in being able to make substantial financial investments in projects outside of Japan for the foreseeable future.  Taxpayers should be concerned about issues with loan guarantee program’s ability to adequately assess the risks of their loan decisions.

The U.S. should immediately halt subsidies and instead focus on developing solar and wind power.

Take Action on Nuclear Subsidies

The administration must take off the blinders, look hard at what is going on in Japan and realize that yes, a catastrophe can happen here.

On last night’s Rachel Maddow Show, Ms. Maddow provided some interesting information about how much radioactive fuel might be on site at the Fukushima Dai-ichi nuclear plant.  We’ve provided a quick overview below, but the show’s presentation and graphics are much better than what we can provide.  Click here to watch the segment on “How much radioactive material is at the Fukushima plant?”

*       Reactor No. 3 is reported to have reprocessed fuel which means there is a mixture of uranium and plutonium in the fuel rods.

**     This information was reported by HKN News Japan, and was verified by MSNBC through Japanese and American nuclear experts as being their best estimate of the nuclear fuel on site at Fukushima Dai-ichi.

***   The spent fuel is less hot and less radioactive than the reactor fuel in the core, but without knowing how old the spent fuel rods are there is know way to know what the total radioactivity house at the plant is.

Back in January, Texans For A Sound Energy Policy (TSEP) filed formal legal contentions with the Nuclear Regulatory Commission (NRC) urging denial of Exelon’s application for an Early Site Permit (ESP) for a proposed nuclear power plant site south of Victoria, Texas.

Yesterday, TSEP appeared at a hearing before a three-judge panel of the Atomic Safety & Licensing Board (ASLB) to press its legal and scientific arguments.  This is the first NRC proceeding since onset of the ongoing Japanese nuclear disaster. 

TSEP argued that nuclear power is a high risk, high stakes business, and that the events in Japan must be paramount in the board’s determination of the suitability of the site for the construction of one or more nuclear power reactors – a determination that includes both safety concerns and environmental impact concerns.  TSEP believes that this site is neither safe nor environmentally acceptable and that the key to preventing nuclear and environmental disasters is to address site selection honestly, openly and comprehensively.

From a safety perspective, TSEP has raised four proposed contentions and noted, from the outset, their concerns with the cavalier attitude of Exelon, and a process that appears designed to deliberately obscure key safety issues regarding the site from the public.

TSEP said that their perception is that Exelon believes that it does not matter if there is faulting, hundreds of oil and gas wells, toxic gas and methane and inadequate water supply as long as the power block itself is not directly affected.  Additionally, there is a total disdain for any instability and uncertainty of the geologic platform for the proposed facility which is silt and clay riddled by fractures and oil and gas penetrations.  That coupled with the fact that there is co-location with toxic and explosive gas  poses potential dangers to the safe operation of a nuclear

TSEP believes good engineering can address many potential safety issues, but that we cannot engineer around issues that are not recognized, studied and evaluated.

In light of what the Fukushima Dai-ichi plant is dealing with, water – which has been a major environmental concern – now shows itself to be a major safety issue.  According to Jim Blackburn, the attorney representing TSEP,

Exelon’s proposed plan includes a cooling pond that is clearly crossed by two and potentially four subsurface faults.  These faults clearly threaten the stability of the cooling pond.  Exelon does not deny this but instead argues that it does not matter if the cooling pond fails because it is not a safety feature.  It seems that the Japanese situation suggests that a reserve supply of water may in fact be a major safety issue.  Without the salt water to pour on the core as a last resort, the situation in Japan would already have been worse.  There is no such fall-back plan here.  The cooling pond would function as a last resort facility, but it may in fact be breached and drained, assuming sufficient water to fill the pond at all.

We hope the NRC will slow some of these license approvals and re-licensing applications down until they have had time to evaluate what worked and what didn’t work when backup systems fail. 

The ASLB will be reviewing and deciding which contentions put forth by TSEP will be heard in a licensing hearing later this year.
