Cooperation on nuclear issues is receiving increased attention in Asia. In Northeast Asia, where the nuclear industry is well-developed, cooperation in the “back end” of the nuclear fuel cycle could help deal with issues such as disposition of spent fuel and long term storage options. In Southeast Asia, where countries are just beginning to introduce nuclear energy, cooperation would be useful ...

The recovery of iodine released during the processing of used nuclear fuel poses a significant challenge to the transmutation of nuclear waste. Iodine-129, a long-lived fission product formed by both commercial nuclear power generation and nuclear weapons production, is released when reprocessing nuclear fuel. Since iodine can be concentrated in the human thyroid, any uncontrolled release of io...

Thorium is an element for possible use as nuclear fuel, because of the fertile property of Th-232, which could convert into U-233 after neutron capture and beta decays. However, thorium based fuels have not been successfully implemented, because of the high cost and the higher complexity compared with once-through uranium fuel. Therefore, the focus of this thesis is on thorium for use in tradit...

the safe and effective management of radioactive waste has been given utmost importance from the very inception of nuclear industry in india and it covers the entire range of activities from handling, treatment, conditioning, transport, storage and finally disposal. radioactive waste is generated at various stages of the nuclear fuel cycle, which includes the mining and milling of uranium ore, ...

Uranium 236 is a long-lived radionuclide which is created from the naturally occurring trace isotope 235U (0.72% abundance) by thermal neutron capture. This process leads to a natural abundance of 236U in the range from 10-14—10-13 relative to the major 238U isotope (236U/238U). 236U is also created during the process of uranium enrichment for nuclear fuel or weapons, and as a waste product fro...

An important goal of nuclear reactor instrumentation is the continuous monitoring of the state of the reactor and the detection of deviations from the normal behaviour at an early stage. Early detection of anomalies enables one to make the necessary steps in order to prevent further damage of nuclear fuel. In the present paper, an on-line core monitoring system is described by means of which bo...

Commercial nuclear reactors and storage facilities for their spent fuel contain large amounts of radioactive material, and are not designed to resist attack. The US Nuclear Regulatory Commission (NRC) has determined, however, that these facilities require only a light defense. This paper shows, without disclosing any sensitive information, that reactors and spent-fuelstorage facilities have vul...

A study of future energy requirements and of the potential of various energy sources (coal, oil, gas, nuclear power, hydropower and solar energy) indicates that the contribution to be made by nuclear fission, now competitive with conventional energy sources, will grow steadily over the next few decades. Whereas the amount of fuel which has to be fabricated each year for the operation of a nucle...
