RL Editorial Notes:

The foregoing link which comprised the entire text of the foregoing 6/4/2014 e-mail leads to an ANS article that appears below.

Although ANS in the oil industry stands for “Alaska North Slope” as in “ANS crude oil,” ANS in the context of the following article stands for American Nuclear Society which is described by Wikipedia as --

“The American Nuclear Society (ANS) is an international, not-for-profit 501(c)(3) scientific and educational organization with a membership of approximately 15,000 scientists, engineers, educators, students, and other associate members. Approximately 900 members live outside the United States in 45 countries. There are 51 U.S. and nine non-U.S. local sections, 24 nuclear plant branches and 34 student sections. ANS members represent more than 1,750 corporations, educational institutions, and government agencies.

“The American Nuclear Society was founded on December 11, 1954. ANS has been a leader in the development of nuclear consensus standards since 1958. The main objective of ANS is to promote the advancement of science and engineering relating to the atomic nucleus. Other purposes are to integrate the many nuclear science and technology disciplines, encourage research, establish scholarships, disseminate information through publications and journals, inform the public about nuclear-related activities, hold meetings devoted to scientific and technical papers, and cooperate with government agencies, educational institutions, and other organizations having similar purposes. In 1955 Walter Zinn was elected as the first president of the ANS.

“The Society publishes the magazines Nuclear News and Radwaste Solutions and three technical journals: Nuclear Science and Engineering, Nuclear Technology and Fusion Science and Technology. The ANS holds an annual meeting in June and a winter meeting in November, both attracting participants from around the world. Through its professional divisions and local sections, ANS conducts separate topical meetings, covering specific subjects in-depth.”

Recap from the 6th Thorium Energy Alliance Conference
Posted on June 4, 2014 by ansnuclearcafe
By Lenka Kollar

The 6th annual Thorium Energy Alliance Conference was held in Chicago, Ill., last week and brought together professionals from the nuclear fields and others interested in energy issues.

Thorium as an energy source is not always a frequent point of discussion within the American Nuclear Society because the existing nuclear fuel cycle in the United States, and that of all other countries that use nuclear energy, is based on uranium. However, the potential for using thorium as an energy source is great and we should keep our minds open to researching alternative nuclear energy technologies (see “The Use of Thorium as Nuclear Fuel” – ANS Position Statement 78).

The conference started with opening remarks from Thorium Energy Alliance Executive Director John Kutsch, in which he explained that we have a “perceptual blindness” to the second- and third-order technologies that today’s research can create. He emphasized that we need to be thinking of the vast possibilities for new nuclear energy technology and the role that thorium can play in advanced reactor designs.

So, why use thorium if we already have a uranium fuel cycle? According to the TEA website, a thorium power plant will produce less than 1 percent of the waste of that from a traditional uranium power plant of the same magnitude. The waste from a thorium plant is also benign in less than 200 years, while uranium power plant waste remains radioactive for over 10,000 years. Also, thorium is much more abundant in the earth’s crust than uranium.

In a liquid fluorite thorium reactor (LFTR) design, thorium and uranium-233 are dissolved in fluoride-based salts to form a liquid fuel. This fuel is pumped between the core and a heat exchanger to transfer heat to a secondary salt loop, which then transfers the heat to a steam turbine, as illustrated in the image above. This technology was first investigated at the Oak Ridge National Laboratory Molten-Salt Reactor Experiment in the 1960s.

If you want to learn more about thorium, check out the “Th” Thorium Documentary video playlist on YouTube, created by one of the TEAC6 conference attendees, Gordon McDowell. You can also see tweets from the event by clicking on #TEAC6 and support the cause through the Energy From Thorium Foundation. In addition, look forward to a new documentary coming out soon about the benefits of nuclear energy and using thorium as fuel, called The Good Reactor.
