The United States’ top nuclear regulator said Friday that atomic energy users, including Japan, must figure out how to ultimately store radioactive waste.

Duane Tilden‘s insight:

>Japan has no final waste repository, not even a potential site. The U.S. government’s plan for building a repository at Yucca Mountain in Nevada has been halted by strong local opposition due to safety concerns.

“In the nuclear community, we of course have to face the reality of the end product — spent fuel,” Macfarlane told reporters.

She urged countries that are contemplating or embarking on a nuclear power program to formulate back-end plans at an early stage.

The new policy under Prime Minister Shinzo Abe’s pro-nuclear government is pushing to restart as many reactors as possible if deemed safe under the new, stricter safety standards that took effect this past summer. The new policy, whose draft was discussed Friday by a government panel, is also expected to stick to Japan’s shaky fuel cycle program despite international concerns about the country’s massive plutonium stockpile.

Japan is stuck with 44 tons of plutonium at home and overseas after unsuccessfully pushing to establish a fuel cycle, with its fast breeder reactor and a reprocessing plant never fully operated. Experts say Japan’s plutonium stockpile poses a nuclear security threat and raises questions over whether Japan plans to develop a nuclear weapon, which Tokyo denies.

Japan also has more than 14,000 tons of spent fuel in cooling pools at its 50 reactors, all of which are offline. Some pools are expected to be full in several years, and are expected to be moved to a dry cask facility just completed in northern Japan.<

PORTLAND, OR–(Marketwired – Oct 29, 2013) – The Green Building Initiative (GBI) applauds the General Services Administration on its recognition of Green Globes® alongside the U.S.

Duane Tilden‘s insight:

>GBI’s growth in the market is due to its commitment to the practicality of its tools for use by building owners, designers, and facility managers as well as its commitment to open, consensus-based review of its technical criteria. In 2010, GBI was recognized for developing Green Globes for New Construction as the first ever American National Standard for a commercial building rating system. As it continues to improve its rating systems based on changes in the market, GBI remains committed to using the American National Standards Institute (ANSI) approved consensus procedures.

“GBI is the only commercial building rating system developer to vet its technical criteria through the ANSI process,” stated GBI Chairman Tonjes. “This helps to ensure that GBI’s rating systems provide the opportunity to evaluate the widest range of buildings using an open, science-based approach to building performance.”

ANSI/GBI 01-2010, also known as Green Globes for New Construction, is due for revision before the end of 2015 based on ANSI periodic maintenance requirements. According to Tonjes, GBI’s ANSI-based rating system review process will begin before the end of this year with the filing of required documents followed by reformation of the technical review committee.

GBI’s tools have a significant focus on both the reduction and efficient use of energy and water in buildings. These, along with other criteria, help reduce building operating costs and their overall impact on the environment.

“Since 2005, the Green Globes product line has evolved to include several updated and expanded tools,” stated Erin Shaffer, vice president of federal outreach at GBI.<

The China Water Crisis: A Global Catastrophe or Wasteful Use?

Learn how the China water crisis will have significant impact on the balance of the world if not reversed, and how you can help, in this WaterFilters.NET post.

Duane Tilden‘s insight:

>The New York Times reports:

Beijing has placed its faith in monumental feats of engineering to slake the north’s growing thirst. The South-North Water Transfer eventually aims to pipe 45 cubic kilometers of water annually northward along three routes in eastern, central and western China. All three pose enormous technical challenges: The eastern and central routes will be channeled under the Yellow River, while the western route entails pumping water over part of the Himalayan mountain range.

The estimated cost of $65 billion is almost certainly too low, and doesn’t include social and ecological impacts. Construction has already displaced hundreds of thousands, and issues the like possible increases in transmission of water-borne diseases have not been properly studied. But Beijing’s calculus is political: It is easier to increase the quantity of water resources, at whatever cost, rather than allocate a limited supply between competing interests.  […]

A recent article by The Economist states:

“The Chinese government would do better to focus on demand, reducing consumption of water in order to make better use of limited supplies. Water is too cheap in most cities, usually costing a tenth of prices in Europe. Such mispricing results in extravagance. Industry recycles too little water; agriculture wastes too much. Higher water prices would raise costs for farms and factories, but that would be better than spending billions on shipping water round the country.”

Economically supporting Chinese regions and corporations that commit to better water usage and sustainability practices may help to change the mindset of many within this nation’s government or industries.  In turn, this could lead them towards exploring more realistic initiatives experiencing success in other parts of the world.<

GE seeks to Clean up Fracking’s Dirty Water Problem

GE has demonstrated technology aimed at addressing one of the biggest challenges with fracking: water pollution.

Duane Tilden‘s insight:

>Concerns about water pollution and other environmental issues related to fracking have led some places, including France and New York State, to block the process. As fracking increases in dry areas and places that lack adequate treatment and disposal options, pressure to block it could grow.

“Water-treatment technology is going to become more and more critical as the industry moves forward,” says Amy Myers Jaffe, executive director of energy and sustainability at the University of California at Davis, and a new member of a GE environmental advisory board. She says the continued use of fracking depends on the “industry getting its act together to do it in an environmentally sustainable way.”

Better water-treatment options could change the way oil and gas producers operate by making it economical to treat water at fracking sites instead of trucking it long distances to large water-treatment facilities or disposal wells. The technology is specifically targeted to places such as the Marcellus shale, one of the largest sources of shale gas in the U.S., where wastewater is far too salty for existing on-site treatment options (see “Can Fracking Be Cleaned Up?” and “Using Ozone to Clean Up Fracking”).

Each fracking well can require two to five million gallons of fresh water, which is pumped underground at high pressure to fracture rock and release trapped oil and gas. Much of that water flows back out, carrying with it the toxic chemicals used to aid the fracking process, as well as toxic materials flushed from the fractured rock.

Producers currently reuse much of that water, but that involves first storing it in artificial ponds, which can leak, and then diluting it, a step that consumes millions of gallons of fresh water. Eventually they can’t reuse the water any more so they need to ship it, often over long distances, to specialized treatment and disposal locations. Transporting the wastewater is expensive, and it comes with a risk of spills. At disposal sites, the wastewater is injected deep underground in a process that can cause earthquakes.

The new technology would make it unnecessary to dilute the wastewater, or transport it for treatment or disposal. […]<

Cities and people are scarce in northwestern North Dakota, but nighttime satellite imagery shows the Bakken Formation aglow with brightly-lit drilling equipment.

Duane Tilden‘s insight:

Northwestern North Dakota is one of the least-densely populated parts of the United States. Cities and people are scarce, but satellite imagery shows the area has been aglow at night in recent years. The reason: the area is home to the Bakken shale formation, a site where gas and oil production are booming.

On November 12, 2012, the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite captured this nighttime view of widespread drilling throughout the area. Most of the bright specks are lights associated with drilling equipment and temporary housing near drilling sites, though a few are evidence of gas flaring. Some of the brighter areas correspond to towns and cities including Williston, Minot, and Dickinson. …
