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?”

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.

I’ve just spent the past few days in a dizzying whirl of activity around SXSW Interactive (or SXSWi)- between ACT Lobby Day yesterday and Monday testifying in/monitoring 3 committees on 7 bills, it was tough to make it to everything I wanted, but over the weekend I had some really amazing experiences.

SXSW logoBy far, the most positive thing I’ve seen here was SXSW had a panel organized on the fly- all about how to help Japan. I knew we were discussing it in different places, but in less than 48 hours from tragedy striking, there were some of the best minds in tech and thought leaders from various industries working together to make disaster relief a priority:   sxsw4japan.org: How You Can Impact Earthquake Relief Absolutely amazing to me the good will and nature of people willing to come together to help complete strangers halfway across the globe. We are blessed to live in such a time.

One of the best panels I went to was Why My Phone Should Turn Off the Stove. Continue Reading »

The tragic events unfolding in Japan demand a re-examination of U.S. nuclear policy.  While stocks in nuclear plummet and nuclear industry lobbyists scramble on Capitol Hill to shore up support for massive federal subsidies to kick-start the stagnate industry, concerns regarding the existing aging fleet are surfacing and should be heeded.  Click here to read more about specific concerns about some of the aging US nuclear fleet.

Amazingly, despite emerging concerns about existing and proposed reactors, the Obama administration has said it will not back off its plans to further prop up the nuclear industry through increased taxpayer-backed loan guarantees and the inclusion of nuclear power technology in the administration’s clean energy standard. The administration has included $36 billion in loan guarantees in its budget proposal for fiscal year 2012. Instead, it 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.

San Antonio’s electric utility, CPS, has halted their negotiations on a power purchase agreement between CPS and STP’s expansion units 3 and 4.  CPS’s CEO, Doyle Beneby, announced that CPS and NRG have mutually agreed to terminate their PPA negotiations at this point. 

It would appear that the issues facing NRG’s Japanese partners (including Tepco, the beleaguered owners of the doomed Fukushima nuclear plant) are giving everyone pause in their relentless pursuit of the STP expansion.

Major US news agencies reporting a hydrogen explosion at Fukushima Dai-ichi No. 2 may have breached the containment vessel. Tepco, the Japanese company that owns this plant has evacuated operators from the area.  There are reports of elevated radiation levels in the area near the plant.
This plant just had its license extended in February.  South Texas Plant (STP) is in the process of extending its license for its 22 year old units 1 and 2.

As of today, several countries have announced intentions to review their nuclear power policies as a result of the unfolding drama in Japan.

Investors dumped Japanese shares Monday, sending the Nikkei down 6.2% amid concerns about a nuclear emergency in the country following Friday’s devastating earthquake and tsunami, with stocks of exporters and plant operators hardest hit.

Analysts say stocks were being largely driven by the quake-related news flow; while news of the devastating tsunami effects in northeastern Japan waned.  Fears spread amid the scramble to contain meltdowns at Tokyo Electric Power’s (Tepco) troubled Fukushima Daiichi nuclear plant as investor attention remained riveted on the No. 1 and No. 3 reactors at the facility, which were damaged by the effects of the quake and tsunami. Selling accelerated in the afternoon following a new explosion at the No. 3 reactor, similar to the one that hit the No. 1 reactor on Saturday.

Tepco’s shares went largely untraded, closing down 24 percent. Goldman Sachs also lowered its rating on the stock to Neutral from Buy and cut its target price 13 percent.

Between Tepco and Tohoku Electric Power, some 15 nuclear power units are in questionable status.

Hitachi and Toshiba, which make nuclear power technology, both sank 16 percent.

Why is the economic news of these Japanese companies of interest to Texas?

Nuclear Innovation North America LLC (NINA), the nuclear development company jointly owned by NRG Energy, Inc. and Toshiba Corporation, are the major financial partners in the two new nuclear units at the South Texas Project (STP).  Last year they announced they had reached an agreement with Tokyo Electric Power Company (Tepco), that owns the Fukushima Daiichi, to also partner in the STP expansion.

NINA was also counting on the Japanese government to provide loan guarantees to the project.  So, of the major financial investments in this Texas nuclear expansion, three are Japanese.  One can easily predict that both the Japanese government and Japan’s nuclear industry’s economic future are going to be tied up for the foreseeable future.  Given this, it would be mind-boggling if the U.S. Department of Energy approved a loan guarantee for STP’s expansion.

The word “meltdown” goes to the heart of the big nuclear question – is nuclear power safe?  Richard Black,  Environment correspondent with the BBC News tries to answer this question and address questions about what is happening at the Fukushima Daiichi plant.   Click here to read the BBC article.

One issue he does bring up is that Fukushima Daiichi is bound to raise some very big questions, inside and outside Japan including here in Texas.

Last year Nuclear Innovation North America LLC (NINA), the nuclear development company jointly owned by NRG Energy, Inc. (NYSE:NRG) and Toshiba Corporation, announced they had reached an agreement with Tokyo Electric Power Company (Tepco), that owns the Fukushima Daiichi, to partner in the two new nuclear units at the South Texas Project (STP).

Tepco has been implicated in a series of cover-ups down the years.

  • In 2002, the chairman and four other executives resigned, suspected of having falsified safety records at Tepco power stations.
  • Further examples of falsification were identified in 2006 and 2007.

As Austin Energy and CPS consider the Power Purchase Agreements NRG is peddling they should look very hard at what is happening in Japan and at TEPCO’s ability to remain a financial partner in STP.

In a Wall Street Journal article by Rebecca Smith (click here to read the entire article), she writes that the unfolding crisis at the Fukushima Daiichi nuclear power plant casts doubt on the fundamental premise that has undergirded the global nuclear industry for five decades: that engineers can build enough redundancy into plant safety systems to overcome dangers.

Peter Bradford, a member of the Nuclear Regulatory Commission at the time of the Three Mile Island accident in Pennsylvania in 1979 (who has spoken to local leaders in Central Texas about numerous issues that should preclude them from becoming partners in or signing power purchase agreements with NRG in the STP expansion), said that the accident exposes shortcomings in risk analysis as well as in engineering.

“The redundancy, such as it was, obviously was inadequate to the event that actually happened,” he said. He said the problem is that certain risks always are discounted in the licensing process as “so highly unlikely that you don’t have to plan for them.”

He said that may be the case in Japan, with an earthquake that apparently exceeded the level that the plant was designed to withstand, possibly compounded by other unexpected technical problems or by the tsunami. It’s not yet known if operator error may have played a role, as it did three decades ago at Three Mile Island.

“The really important question,” Mr. Bradford said, “is to ask how different licensing bodies decide what risks have to be guarded against and see if that analysis was adequate.”

Even Texas Congressman Joe Barton, who is chair emeritus of the House Committee on Energy and Commerce and a strong proponent of the push for nuclear expansion in the U.S. is now saying:

. . . that nuclear plants are designed with earthquakes in mind. “They’re supposed to be double and triple redundant…. If I’ve been to one briefing, I’ve been to a dozen, given by the industry, where they talk about all the safety features and the built-in redundancy features that protect the reactors in the event of an accident, a natural disaster, even a terrorist attack.”

Mr. Barton added that he’s “very puzzled that, even as big as this earthquake was, the plant didn’t meet those standards. That’s something that even proponents of nuclear power want to get to the bottom of…. I believe very strongly in the future of nuclear power, but those who support it have to insist that the safety redundancy features perform.”

To date, the major stumbling block to the US rushing headlong into a “nuclear renaissance”  has been the huge financial cost and risks involved in building new nuclear plants in down economy.  It is tragic and unfortunate that it is taking the failure of these Japanese plants in the wake of what surely is one of the worst disasters in Japanese history to cause the US to look more closely at their rush to increase our country’s nuclear portfolio.

The Federal Energy Regulatory Commission (FERC) wants to know the reasons for the Texas power generation outages and for the interruptions in natural gas delivery to New Mexico.

As Texas officials began looking into the causes of the Texas electricity blackouts, New Mexico was holding its own hearings.  The ripple effect felt by down pipeline states when Texas’ electric grid and natural gas supplies went awry during an abnormally cold winter storm in February of this has prompted the federal agency to examine how to ensure that a new fleet of natural gas plants around the country can get plenty of fuel.

This has major implications for a state that has been expanding natural gas drilling operations exponentially over the past several years, many think to the detriment of the environment and the health of those who live around those operation.  Just ask the folks in the Barnett Shale region of North Texas.  Some of them might even be able to light their water taps on fire for you.

According to an update from the Nuclear Information and Resource Service (NIRS) an explosion has occurred at Fukushima Daiichi Unit 1.

[youtube=http://www.youtube.com/watch?v=jMEV-_X5b_8]

Video of the aftermath of the explosion shows that the containment building
has been destroyed.

[youtube=http://www.youtube.com/watch?v=ELR3hdlce2g]

The NIRS update goes on to explain, in a General Electric Mark I reactor, the containment building is fairly weak and is considered the secondary containment. The primary containment is a steel liner that surrounds the reactor core. So far, video and photos have not been clear enough for us to determine whether this steel liner is intact.

Radiation levels at the site are reported to be 1,015 micro/Sieverts per hour. This is roughly equivalent to 100 millirems/hour. The allowable annual dose for members of the public from nuclear facilities in the U.S. is 100 millirems/year. The allowable annual dose for nuclear workers is 5,000 millirems/year. The average annual background dose from all radiation sources in the U.S. is about 360 millirems/year.

The explosion in Unit 1 was almost surely a hydrogen explosion. Pressure has been building up in the containment since offsite power was lost to the reactor because of the earthquake/tsunami. The GE Mark I reactor design is called a “pressure suppression” design. Rather than be built to withstand large pressure increases, General Electric sought with this design to attempt to reduce such increases in an accident scenario. The design has been criticized by independent nuclear experts and even Nuclear Regulatory Commission staff for many years (see: http://www.nirs.org/factsheets/bwrfact.htm).  In this case, the design clearly did not work. 24 U.S. reactors use the GE Mark I design.

The evacuation zone around the site has been expanded to 20 kilometers (about 12 miles). Another reactor at Fukushima Daiichi, Unit 2, is reported to be without cooling capability at this time. Three reactors at the nearby Fukushima Daini site are reported to be without cooling capability. These are GE Mark II designs, which are considered a mild improvement over the Mark I design. Both sites are on the Pacific Ocean, about six miles apart.

The Public Utility Commission (PUC) sunset bill (H.B. 2134) would give the PUC the authority to approve or change the annual budget of the Electric Reliability Council of Texas (ERCOT),  stipulates that no member of the PUC could work for ERCOT for at least two years after he or she had stepped down, and fines would quadruple (from a maximum of $25,000 per day to $100,000 per day) for any company found to have manipulated the electric market for its own gain under the Sunset bill that will be heard in House State Affairs Committee on Monday, March 14th.

Rep. Burt Solomons (R-Carrollton)

State Rep. Burt SolomonsHouse Bill 2134 largely tracks the recommendations approved in January by the Sunset Advisory Commission and includes language that the Carrollton Republican has been advocating for at least two years to cut the number of ERCOT board members who have ties the electric industry.

State Affairs is scheduled to take up the Sunset bill during its hearing that convenes 30 minutes after the House adjourns Monday. The meeting will be held in Room 140 of the Reagan Building northwest of the Capitol.

This morning’s quake on the other side of the world has implications for nuclear plants here in the U.S.   The Nuclear Regulatory Commission (NRC), through its regional office in Arlington, TX, announced they are closely monitoring this situation – the Japanese earthquake and subsequent tsunami – as it unfolds with respect to nuclear facilities within the United States.

Earlier today the NRC issued a “notice of unusual event” (NOUE) at the Diablo Canyon Power Plant, located near San Luis Obispo, CA.  In addition to the Diablo Canyon plant, the NRC is also monitoring the San Onofre nuclear power plant, the Humboldt Bay spent fuel storage site and NRC-regulated nuclear materials sites in Hawaii and Alaska to name a few.

A push to build new nuclear facililties in the U.S. has catapulted the nation’s aging nuclear industry into the limelight and the NRC is being quick to assure the public that nuclear power plants are engineered to withstand environmental hazards, including earthquakes, tsunamis and other natural disasters.

The NRC claims plants are designed to take into account the most severe natural phenomena historically reported for the site and surrounding area.  Still, while the emergency situation at two Japanese plants is seemingly contained at this point, with one Texas plant situated on the hurricane prone Texas Gulf coast and the other in the middle of tornado alley, one has to wonder . . . what if we haven’t yet seen the most severe natural phenomena for those areas?

In the wake of the massive 8.9-magnitude earthquake and tsunami that hit Japan earlier today, the government has issued an evacuation order to thousands of residents near Fukushima No. 1 power plant in Onahama city, about 170 miles northeast of Tokyo, after its primary and emergency cooling systems failed (there are six nuclear units located at this facility run by Tohoku Electric Power Company’s (TEPCO) which is the Japanese power company that has expressed interest in investing in NRG’s expansion at South Texas (nuclear) Project). 

Fukushima Nuclear Plant

Japan’s nuclear safety agency said workers are currently scrambling to restore cooling water supply at the facility, but that there was no prospect for an immediate success.  So far there have been no reports of any radiation leaks.

UPDATE:  At 4:30 CT on Friday, March 11th all the U.S. news outlets were breaking news about radiation levels in the control room of the No. 1 reactor of the Fukushima nuclear power plant reaching around 1,000 times the normal level and that some radiation has also seeped outside the plant, prompting calls for further evacuations of the area.

Japan's nuclear plants near the earthquake epicenter from MSNBC (http://www.msnbc.msn.com/id/42025882/ns/world_news-asiapacific/)

The quake struck just under 250 miles northeast of Tokyo, the U.S. Geological Survey said.  It was followed by more than a dozen aftershocks, one as strong as 7.1, and eleven nuclear reactors were automatically shut down in the affected area, according to the Japanese government, but they haven’t confirmed any effects induced by radioactive materials outside the facilities.

In addition to the situation at the Fukushima plant, at the TEPCO’s nearby Onagawa facility, which is in the worst-hit Miyagi prefecture north of the Fukushima facility, a fire broke out at the plant following the quake. The blaze occurred in a turbine building, which is separate from the plant’s reactor, and was reported as being quickly extinguished.  However, there seems to be some concerns about the cooling system at this plant too and the the Japanese government has also declared a state of emergency at this facility.  Another unit at Onagawa is reported as experiencing a water leak, though it is unclear whether the incident is significant.

Obviously, we don’t know if any of these reports will lead to a serious nuclear event or not, but the isolated reports so far are worrisome.  

In this region, earthquakes are a design basis accident which nuclear plants are supposed to survive, but engineering, while it can take many factors into consideration and build in multiple backups, can only be  tested by an actual natural disaster.  The problem is, under such circumstances, if there is a failure, one can only assume that other systems (transportation, power availability, access to experts and technicians – all the ancillary things ones needs to deal with a containing a serious event) will also be disrupted.  So when a nuclear “expert” tell you that a plant is designed to withstand a massive hurricane, storm surge, tornado, or earthquake, keep that in mind.

Texas counties served by AACOG

San Antonio, which sits just north of what many say is one of the largest oil and gas reserves in the country known as the Eagle Ford, is a heart beat away from violating federal air quality standards for ground-level ozone. It seems it is only a matter of time before the increased emissions from the Eagle Ford could drift up on prevailing winds, pushing the area out of compliance.

With drilling expected to increase over the next decade, those responsible for this region’s air quality say the increased pollution could make it difficult to remain under federal limits.  In the past decade, San Antonio’s ozone levels have decreased by 13 percent while its population has increased 13 percent, managing to stay just ahead of federal standards.  However, once a region falls out of compliance, efforts to get back in are time-consuming, politically unpopular and expensive.

It is going to be a tough contest for the environment to compete with the hype about the economic benefits (which always fail to take into account the economic costs to the region for these types of activities – increased health care costs, decreased quality of life costs, and the cost of coming back into compliance with federal air quality standards).

According to a study by the Center for Business Research at the University of Texas at San Antonio and commissioned by America’s Natural Gas Association:

Activity in the Eagle Ford in 2010 alone generated more than $2.9 billion in total revenue, supported roughly 12,600 full-time jobs and provided nearly $47.6 million in local government revenue.

Last year there were 72 active oil leases, some of which may have more than one well, and 158 producing gas wells.

However, the number of drilling permits issued by the Texas Railroad Commission, which regulates the state’s oil and gas industry, has reached 1,132 as of February. In just one year, the output of crude oil, condensate and other liquids nearly quadrupled to 3.9 million barrels.

And the boom has just begun; the UTSA study forecasts that 5,000 more wells could be drilled by 2020.

So far, no regulatory agency has begun comprehensive air monitoring in the Eagle Ford area, meaning there’s no baseline to measure any increased pollution.

Models for other regions of the country show drilling and related emissions can increase ground-level ozone significantly and the sheer volume of drilling that’s expected over the next decade, will require Alamo Area Council of Governments (AACOG) to add a new category, for drilling and recovery, into its air pollution forecasting models.

The San Antonio Express News writes about the area:

The Eagle Ford shale covers a swath roughly 50 miles wide and 400 miles long, from Maverick and Webb counties sweeping north and east up to Leon and Houston counties, but not including Bexar County. Unlike other large shale formations that have recently been tapped, the Eagle Ford includes a good deal of oil, mostly along the northern reach.

Because oil prices are high and natural gas prices low at the moment, there’s more activity in the oil region at this time, industry analysts say.

Drilling has occurred in South Texas for decades, but the oil and gas trapped in the deeper, dense rock layers once were too expensive to reach. Advances in drilling technology, most notably hydraulic fracturing and horizontal drilling, have allowed an unprecedented amount of hydrocarbons to be extracted.

“Fracking,” as it’s known, forces millions of gallons of water, mixed with sand and a variety of chemicals, into shale formations, forcing open fissures to allow the natural gas and oil to escape. Horizontal drilling allows for one hole to be drilled vertically, then one or more pipes to branch out into the shale.

Together, these techniques have spawned a natural gas boom in the country, with some industry experts estimating a 100-year supply of a fuel that burns more cleanly than coal and could help push the country toward energy independence.

In other parts of the country the boom is well under way, and as drilling has increased, so have complaints about its environmental impacts, most notably drinking water contamination.  While it remains unclear whether fracturing has contaminated drinking water, the EPA last month agreed to study the entire life cycle of the gas production process, to determine how it can affect drinking water supplies.

While water has gotten the lion’s share of the attention thus far, air quality concerns also are increasing and seem to be the area of most concern to San Antonio as they look toward increased drilling activities in the region.  Let’s hope they can stay ahead of this new boom.
