TEPCO Resumes Decontaminating Water to Cool Reactors

Plant Status

  • Tokyo Electric Power Co. (TEPCO) resumed decontaminating water at the Fukushima Daiichi nuclear power plant after fixing a software flaw that caused an automatic shutdown of the decontamination system. After a short investigation identified the flaw, the problem was corrected and decontamination resumed. The decontaminated water is being reused to cool reactors at the facility.
  • TEPCO has begun transfer of water contaminated at lower radiation levels from tanks in the reactor 6 turbine building to a barge moored near the Fukushima Daiichi plant. The tanks hold about 12,000 tons of contaminated water, and workers will transfer about 8,000 tons to the barge.
  • TEPCO is making progress on a new cooling water system for the used fuel storage pool at reactor 3. The company is testing the system and plans to have it operating next week. The reactor 2 fuel pool is at full cooling capability, but TEPCO is still considering options for cooling water for the reactor 4 storage pool, where piping and valves in the pool’s cooling water system were damaged in March by a hydrogen explosion in the upper portion of the containment building. TEPCO said it intends to have the cooling systems in all fuel storage pools operating by mid-July, but that issues with the damaged reactor 4 system may delay progress.
  • TEPCO sent an American-supplied robot into the reactor 3 building to remove highly radioactive sand, dust and rubble. The robot is manually operated from outside the building. If the effort is successful, TEPCO will begin preparations to inject nitrogen to prevent hydrogen explosions. The company is already injecting nitrogen into reactors 1 and 2.
  • Contrary to earlier reports, TEPCO said that three workers at the Fukushima site have been exposed to more than 25 rem of radiation—the legal limit for plant workers in an emergency situation. For comparison, a CT scan results in 1 rem of radiation exposure to a patient.

Industry/Regulatory/Political Issues
  • TEPCO’s new president, Toshio Nishizawa, visited towns near the Fukushima Daiichi facility and apologized to their mayors for the difficulties caused by the accident. The mayors said their constituents expect TEPCO to offer compensation to those who have or will suffer financial losses in their businesses because of the accident, not just those evacuated from their homes.
  • The Japanese government is recommending that 113 households evacuate from four districts within the city of Date. Higher levels of radiation have been detected sporadically in the affected districts near Fukushima Daiichi. Evacuation is voluntary and those who choose to move will be compensated.
  • Reports in the Japanese media on radiological impacts say urine samples from 10 children in the city of Fukushima showed small amounts of radioactive cesium.

Media Highlights
  • Tom Fanning, chairman, president and CEO of Southern Company, explains seven steps that the U.S. industry is taking to respond to the Fukushima accident in a column for U.S. News & World Report.
  • Reuters reports on TEPCO’s second round of compensation to people affected by the Fukushima Daiichi event, with each family receiving up to 300,000 yen (about $3,700). The first round earlier this year paid as much 1 million yen (about $12,400) per family.

New Products
  • NEI has launched a new website, Safety First, dedicated to Fukushima to provide up-to-date information on developments in Japan and steps that the industry is taking to enhance safety and emergency preparedness at America’s commercial reactors.

Upcoming Events
  • The task force reviewing U.S. Nuclear Regulatory Commission processes and regulations in light of the accident at Fukushima is expected to release its report on July 12. The task force will brief the commissioners on the report at a July 19 public meeting.

While words and numbers can explain a lot, below is the applicable chart that shows trends in U.S. energy production since 1973. Nuclear energy surpassed renewable energy in the early 1990s and has been ahead for most of the last 20 years... you say

Really - and how much money went to funding nuclear infrastructure vs renewable. The reliable funding for renewables projects has only just started and its smashing nuclear down within the first 10 years on any real funding. Nuclear has had over 50 years to prove itself but no still sitting the costing us on the managing the old waste - nowhere to put, no easy way to make it go away, just keeping adding to the bottom line. Nice looking technical argument though with all your graphs...but whattya lets try that same analysis but follow the funding..

you say...it looks like the Congressman’s news release is trying to hide the billions in loan guarantees, production tax credits, grants, etc. made available to renewables in a previous stimulus bill…...

you are not really going to start comparing nuclear subsidies against renewable are you? what a joke....make sure you start at the beginning.

you say ..And remember: not downplaying the seriousness of the accident, of course, but the health and economic issues resulting from the earthquake and tsunami were fantastically large.).. are you kidding me - you clearly just did downplay. The entire Japanese culture has changed in a minute. Their children are dying from radiation poisoning, their exports are contaminated, the compensation is already in the trillions...please dont downplay this atrocity -have you no soul?

one last thing - you got real pretty pictures of power plants. They may already have construction costs from the taxpayers to move dirt around .. but there is no approved license for those new reactors... lets keep those fact straight huh?

Clearly the hysterical and fear-mongering reactions of the socialist countries of Germany and Italy with shutting down their nuclear industry have given even more fodder to the unreasonable claims for a secure, safe, and clean energy sources for the world...yeah that sux for you - sorry about that.

Anon, certainly with all your sneer and jeer you could have at least provided a link or reference to something.

how much money went to funding nuclear infrastructure vs renewable.

Check out the second page from this analysis. Since 1950, nuclear has received 9% of all federal energy incentives compared to 18% for renewables. Fossil fuels, out of everyone, have received the lion's share of incentives.

Their children are dying from radiation poisoning, their exports are contaminated, the compensation is already in the trillions

Let's come back to reality please. The dose rates have been tracked since day one and one of the indicators of how bad the radiation is, are from the plant workers. Even the worst doses aren't expected to be fatal. Here's what IAEA noted last month:

To date no health effects have been reported in any person as a result of radiation exposure from the nuclear accident.

Back to you:

Clearly the hysterical and fear-mongering reactions of the socialist countries of Germany and Italy with shutting down their nuclear industry have given even more fodder to the unreasonable claims...

Interesting how you give credit to Germany and Italy for being "hysterical and fear-mongering" in their decision-making process. Any thoughts about why nearly every other country is still sticking with nuclear, even most likely Japan?

Activists' Claims Distort Facts about Advanced Reactor Design

Below is from our rapid response team . Yesterday, regional anti-nuclear organizations asked federal nuclear energy regulators to launch an investigation into what it claims are “newly identified flaws” in Westinghouse’s advanced reactor design, the AP1000. During a teleconference releasing a report on the subject, participants urged the Nuclear Regulatory Commission to suspend license reviews of proposed AP1000 reactors. In its news release, even the groups making these allegations provide conflicting information on its findings. In one instance, the groups cite “dozens of corrosion holes” at reactor vessels and in another says that eight holes have been documented. In all cases, there is another containment mechanism that would provide a barrier to radiation release. Below, we examine why these claims are unwarranted and why the AP1000 design certification process should continue as designated by the NRC. Myth: In the AP1000 reactor design, the gap between the shield bu...

How many nuclear plants does it take to meet the world's energy needs?

Several weeks ago Joshua Pearce at Clarion University in Pennsylvania released a study titled “ Thermodynamic limitations to nuclear energy deployment as a greenhouse gas mitigation technology .” In the study he stated... nuclear energy production would have to increase by 10.5% per year from 2010 to 2050 to both replace fossil-fuel-energy use and meet the future energy demands. This line, of course, made the headlines and has been picked up by several outlets and blogs . When looking into his calculations for this statement, he made one assumption error that overstated the above sentence by nearly a factor of three. Page 121, Section 4.1 of the study states: Richard Smalley pointed out that in 2004, the global economy consumed the equivalent of 220 million barrels of oil per day, which converted into electricity terms is the equivalent of 14.5 TeraWatts (TW), or 14,500,000 MegaWatts (MW) (2005). … With a nuclear plant having about 1000 MW (1 GW) of capacity, we would need 14,500...

What Happens During a Refueling Outage?

You may have noticed over the past few weeks that a number of nuclear plants are shut down for refueling outages or are resuming operations after just returning from one. This type of routine outage usually occurs in the spring or fall when electricity demand is low so that nuclear reactors can replace about one-third of the spent fuel rods with new fuel and conduct other routine maintenance and repairs at the plant. To get a better sense of how refueling works at a nuclear energy facility, I spoke with Marcus Nichol, NEI’s senior project manager for used fuel storage and transportation, and asked him to explain the basics. Why does a nuclear plant need to replace one-third of its fuel? Nichol: The main purpose of a refueling outage is to replace older fuel that is depleted—meaning it can no longer efficiently produce energy from nuclear fission reactions—with new fuel. This “used fuel” has typically been used in the reactor for four-and-a-half to six years before it is pe...
