To assure safe shutdown of a nuclear power plant, there must always be reliable means of decay heat removal provided, in last resort, by an Emergency Core Cooling System (ECCS). Currently the majority of nuclear power plants in the US utilize diesel generator sets as on-site emergency power generating units. In addition to the loss of off-site power, plants can lose their on-site AC power, a co...

The performance of a superconducting linear accelerator (SLA) system for pellet injection in fuel nuclear fusion reactors was investigated numerically. To this end, numerical code using the finite element method developed to analyze shielding current density and dynamic motion high-temperature thin film SLA system. computational results showed that applying an exponential electromagnet, signifi...

Dædalus Winter 2010 This two-volume special issue of Dædalus highlights the challenges associated with the global expansion of nuclear power. The topics covered include environmental impacts, nuclear safety, and the economics of nuclear power production, but the major emphasis is on nonproliferation and security aspects. To develop an understanding of possible problems and their potential solut...

Fuel cycle cost of a fast reactor is expected to play an important role of compensating for higher capital cost of a Fast Reactor and keeping the unit energy cost competitive. PFBR fuel cycle cost has been worked out by a committee constituted for the purpose. The cost has been worked out for a peak fuel burn-up of 1,00,000 MWd/t. The basic components of the PFBR fuel cycle are fabrication cost...

the industrial growth of any developing country largely depends on the availability of abundant energy resources. according to the energy survey carried out by international atomic energy agency, (1) the contribution which nuclear energy will make towards the total energy requirements of the developed countries of the world by the end of the century will be about 50%. in iran by the year 1992 t...

The first step in investigation of thorium fuel is evaluation of the results obtained from the spectral code for this type of fuel. The benchmark summarized by IAEA in 2003 was used for partial validation of the code HELIOS 1.9. The benchmark was focused on a comparison of the methods and basic nuclear data. Acceptable results of benchmark comparison allowed examining and comparing different ad...

Nuclear energy is among the most viable alternatives to our current fossil fuel-based energy economy. The mass deployment of nuclear energy as a low-emissions source requires the reprocessing of used nuclear fuel to recover fissile materials and mitigate radioactive waste. A major concern with reprocessing used nuclear fuel is the release of volatile radionuclides such as xenon and krypton that...

"It is not a wise choice!", this was the reaction of my father when I applied for nuclear medicine residency program 26 years ago. The old retired officer continued that hi-tech nuclear medicine is dependent on multiple advanced sections that may not be easily available especially in the developing countries. Now he is not alive to see that political misconducts have added fuel to the fire. Glo...

Fast reactor fuel cycle (FRFC) is regaining importance because of its vital role in the long term development of nuclear power. The safety issues associated with the fast reactors are now well understood and newer designs can address those from the lessons learned in the past. The same cannot be ascertained about their safeguards issues. Primary reason being the presence of special nuclear mate...
