Climate change also causes changes in the oceans, which absorbs about one-fourth of the carbon dioxide emitted to the atmosphere each year. These techniques have widely contributed to the understanding of past and present ocean conditions and to predicting the impact of climate change, according to sources from the International Atomic Energy Agency IAEA. Nuclear and isotopic techniques are used contribute to the understanding of this process. Some corals, pteropods, bivalve mollusks and phytoplankton may be particularly sensitive to changes in seawater chemistry. The energy they spend overcoming the higher acidity could reduce the energy available for physiological processes such as reproduction and growth. Coral reefs are also highly affected.

By Aug 11, London - Two important nuclear anniversaries take place in August. The first - for many the most significant - is that commemorating the dropping of the first nuclear bomb on the Japanese city of Hiroshima on August 6, This not only brought a rapid end to the World War 2, but also introduced the world to the realities of nuclear devastation, defining much of the global military and political dynamics of the second half of the twentieth century. The second event is likely to receive less notice. But it has in its way been just as significant. This was the organisation of the first Atoms for Peace conference. Described at the time as "the biggest scientific extravaganza ever held", 1 delegates from 73 nations gathered in Geneva, Switzerland, for four days in August to discuss the peaceful use of nuclear energy, and help establish the basic parameters by which its potential could be exploited by developed and developing countries alike. The Geneva meeting was part of a broader initiative launched by United States President Dwight D Eisenhower to handle simultaneously the threats and promises of nuclear technology.

A coprocessing solvent extraction flowsheet for recovery and purification of light water reactor LWR fuels has been developed.

This flowsheet never completely separates uranium from plutonium. The flowsheet has changed operation of the partitioning contactor to achieve partial partitioning of uranium and plutonium.

Partial partitioning has been demonstrated with simulated feeds and irradiated LWR fuel solutions with hydroxylamine nitrate reductant to concentrate the plutonium by factors of 6 to Nitrite was shown to interfere with the reduction of plutonium. Increased hydroxylamine concentrations gave normal reduction behavior.
