using thorium has proven to be extremely difficult and non-practical, although proof-of-concepts of the contrary also have been proposed. Despite all the favorable factors, and use in commercial reactors in the past, interest in thorium diminished in the late 1980s due to various reasons. Critics of thorium claim that the advantages are overstated and it is unlikely to be a useful source of energy. Experts point the adverse economics and the availability of plentiful sources of energy that will deter full commercialization of thorium based energy. These and other issues regarding the use of thorium have been debated.


Advocacy for thorium

One of the stated objectives of TEA is the vigorous advocacy for use of thorium as a nuclear fuel. TEA through its activities reaches out to scientists, engineers, government official, policymakers, and lawmakers to sensitize about the advantages of using thorium as a fuel. TEA has conducted a number of publicity campaigns and social media based outreach activities. TEA has emphasized the research and development done in the USA during the 1950s to 1970s period on thorium based reactor designs and fuel cycle options. Of particular interest was the

and the supply chain infrastructure to support it. Another aim of TEA is supporting the reemergence of a Western Rare Earths Infrastructure by bringing together rare-earth producers leading to the establishment of a consortium for refining rare earths and sequestering thorium for future use. TEA supports changes in existing thorium regulation in the US to promote safe production and stockpiling of thorium as a by-product of associated mineral industries activity.


Activities

TEA proposes to leverage education and training activities by: *creating educational resources and textbooks *providing scholarships *facilitation of expert speakers *producing museum exhibits presenting thorium based energy TEA plans to engage politicians through round-table discussions and provide them with expert opinion,

TEA facilitates experts to appear on radio and television and participate in group discussions and provide interviews. In this direction TEA generates a large quantity of its own media including,

, books and articles. TEA sponsors advertising campaigns in print, television and targeted mail. Thorium Energy Alliance has supported a dozen research projects at the Nanotechnology Lab at University of Missouri St Louis (UMSL), which is located in an Economic Opportunity Zone. Thorium Energy Alliance has supported Outreach to youth through stem-based organizations such as Generation Atomic, North American Young Generation in Nuclear, and Mothers for Nuclear, encouraging young people to get involved in the industry. The Thorium Energy Alliance website has added resources for international organizations and National Labs in the USA as well as industry and Military.The website acts as a resource and an encyclopedia for the history and applications of thorium as well as or repository of all of conference information and related papers and topical documents. Thorium Energy Alliance has offered Techno-Economic support for the development of nuclear medicines, such as Bismuth and Actinium, derived from Thorium extraction processes. Thorium Energy Alliance has worked with Rare Earth organizations and the critical minerals institute (CMI) to solve the critical materials issues in the United States and the Western world by providing thorium policy guidance with the goal to allow a new domestic Rare Earth Metals industry to start. In the future, TEA plans to track the milestones in the creation of a thorium economy. One of the proposed methods will be to create a thorium and related technology stock portfolio and a Thorium ETF, which will allow the public to track and participate in the growing value of the thorium economy.


Annual Conferences

TEA organizes regular annual conferences since 2009, where scientific sessions and cross-cutting energy and fuel management discussions bring together a cross-section of interested domain experts. The inaugural conference in 2009 took place in Washington D.C., followed by California (2010), Washington D.C. (2011), and Chicago (2012). The 2013 annual conference was held in Chicago, May 30–31.

on October 1st, 2019. The eleventh conference, TEAC11, will be held on October 13 – 15 2022 in ABQ NM , at the national nuclear energy Museum in Albuquerque. TEA has sponsored the production of a new exhibit on thorium energy and advanced reactors.  The conference is being put on with participation of the University of New Mexico, Abilene Christian University Nuclear Department, the nuclear museum, and the support of several of the startups that TEA has assisted with technological support and policy information.
