Radiation degrades nuclear waste-containing materials faster than expected
New method enlists NMR to test durability of mineral-based waste forms
Minerals intended to entrap nuclear waste for hundreds of thousands of years may be susceptible to structural breakdown within 1,400 years, a team from the University of Cambridge and the Pacific Northwest National Laboratory reported in the Jan. 11 issue of Nature.The new study used nuclear magnetic resonance, or NMR, to show that the effects of radiation from plutonium incorporated into the mineral zircon rapidly degrades the mineral’s crystal structure.
This could lead to swelling, loss of physical strength and possible cracking of the mineral as soon as 210 years, well before the radioactivity had decayed to safe levels, said lead author and Cambridge earth scientist Ian Farnan.
According to current thinking, highly radioactive substances could be rendered less mobile by combining them, before disposal, with glass or with a synthetic mineral at a very high temperature to form a crystal.
However, the crystal structure can only hold the radioactive elements for so long. Inside the crystal radioactive decay occurs, and tiny atomic fragments called alpha particles shoot away from the decaying nucleus, which recoils like a rifle, with both types repeatedly blasting the structure until it breaks down.
This may increase the likelihood for radioactive materials to leak, although co-author William J. Weber, a fellow at the Department of Energy national laboratory in Richland, Wash., who made the samples used in the study, cautioned that this work did not address leakage, and researchers detected no cracking. Weber noted that the “amorphous,” or structurally degraded, natural radiation-containing zircon can remain intact for millions of years and is one of the most durable materials on earth.
Some earth and materials scientists believe it is possible to create a structure that rebuilds itself after these “alpha events” so that it can contain the radioactive elements for much longer. The tests developed by the Cambridge and PNNL team would enable scientists to screen different mineral and synthetic forms for durability.
As well as making the storage of the waste safer, new storage methods guided by the NMR technique could offer significant savings for nations facing disposal of large amounts of radioactive material. Countries including the United States, Britain, France, Germany and Japan are all considering burying their nuclear waste stockpiles hundreds of meters beneath the earth’s surface. Doing so necessitates selection of a site with sufficiently stringent geological features to withstand any potential leakage at a cost of billions of dollars. For example, there is an ongoing debate over the safety of the Yucca Mountain site in Nevada. A figure published in Science in 2005 put that project’s cost at $57 billion.
“By working harder on the waste form before you started trying to engineer the repository or choose the site, you could make billions of dollars worth of savings and improve the overall safety,” Farnan said.
“At the moment, we have very few methods of understanding how materials behave over the extremely long timescales we are talking about. Our new research is a step towards that.
“We would suggest that substantive efforts should be made to produce a waste form which is tougher and has a durability we are confident of, in a quantitative sense, before it is stored underground, and before anyone tried to engineer around it. This would have substantial benefits, particularly from a financial point of view.”
PNNL senior scientist and nuclear magnetic resonance expert Herman Cho, who co-wrote the report, said: “When the samples were made in the 1980s, NMR was not in the thinking. NMR has enabled us to quantify and look at changes in the crystal structure as the radiation damage progresses.
“This method adds a valuable new perspective to research on radioactive waste forms. It has also raised the question: ‘How adequate is our understanding of the long-term behavior of these materials?’ Studies of other waste forms, such as glass, could benefit from this technique.”
The collaboration was funded by Britain’s Engineering and Physical Sciences Research Council and the U.S. DOE, with support from the PNNL-based Environmental Molecular Sciences Laboratory.

Founded on August 23, 1890 by Emilio Rangel Pestana, the “Bolsa de Valores de São Paulo” (São Paulo Stock Exchange, in English) – BOVESPA – has a long history of services given to the stock market and the Brazilian economy. Until the middle of the 1960s, BOVESPA and the other Brazilian stock markets were state corporations, tied with the state secretary of finances and brokers were government-appointed.
With the reforms of the national financial system and the stock market implemented in 1965/66, the stock markets had assumed the institutional role that keep until today, changing to non-profit civil associations, with administrative, financial and patrimonial autonomy. The old individual figure of the broker of government securities was substituted by the commercial broker.
BOVESPA’s Bulletin 2006 January 9, 2007
Focus: 26 IPOs and several Public Offerings raised USD 13.2 billion through BOVESPA in 2006, a year that also marked the highest level of BOVESPA’s market capitalization, with USD 723 billion. – Foreign Investment Balance in 2006 BOVESPA’s Foreign Investment Balance registered an inflow of USD 846 million in 2006.
This figure includes the net inflow of USD 496 million in December, resulting from purchases of USD 9.8 billion and sales of USD 9.3 billion, as shows the table below:
* This information is calculated using the monthly closing exchange rate of the Central Bank of Brazil. – Novo Mercado
and Levels of Corporate Governance The IGC (Corporate Governance Index) closed 2006 up, after a positive variation of 7.1% in December. The index is composed of 94 companies: 44 of Novo Mercado and 50 of Level 1 and 2. The 94 companies of Novo Mercado and of the Levels of Corporate Governance now represent 58% of the total market capitalization of BOVESPA, as well as 58% of the total trading value of BOVESPA. Last month, four new companies joined Novo Mercado. Accumulated data in the year show that BOVESPA’s capital raising activity through IPOs and Public Offerings amounted to USD 13.2 billion, as shows the table: IPOs – CAPITAL RAISED *
This information is calculated using the Central Bank of Brasil exchange rate on the first day of Trading. – Market Capitalization BOVESPA’s listed companies market capitalization reached an overall high in 2006, amounting to USD 723 billion (or BRL 1.54 trillion) in the end of the year. – BOVESPA’s Indices Performance in December IBOVESPA reached its overall BOVESPA’s other indices performance was time record 5 times in also positive in 2006: December, closing the trading – IBrX: +36% at 14,567 day of the year 2006 at 44,526 – IBrX-50: +33.7% at 6,450 points. – ISE: +37.8% at 1,433 In the month, IBOVESPA had a – IVBX: +34.1% at 4,734 positive variation of 6.0%, – IEE: +40.8% at 13,985 and a performance of 32.9% in – ITEL: +10.7% at 1,053 2006. – Investors’ Participation on Monthly Trading Turnover The monthly trading turnover was pushed once again by International Investors, that led 34.1% of the value traded. – Trading Value and Number of Trades Statistics In December, BOVESPA turned over BRL 60.1 billion or USD 27.9 billion.
The daily average stood at 98,534 trades, worthing BRL 3.1 billion or USD 1.5 billion. – Cash, Options and Forward Markets Evolution Cash Market accounted for 92.8% of the total financial activity registered in the month, followed by Options Market (3.9%) and Forward Market (3.3%). – Fixed Income Instruments Trading in BOVESPA In December, five Receivables Investment Fund and ten Corporate Bonds have started to be traded on BOVESPA Fix and SOMA Fix Markets. The trading value of BOVESPA´s Fixed Income markets turned over BRL 20.2 million or USD 9.4 million.
