Reprocessing Nuclear Fuel

Handling of the radioactive wastes is dependent on the time taken for half the atoms of the radionuclides to decay. The wastes with long half-life are easier to handle compared to those wastes with short half-life. Reprocessing of nuclei waste is mainly objected to safeguarding human population and the environment prior to releasing the wastes to the environment. This process mainly reduces the radionuclides concentrations in the waste, which are presumed harmless. Common radioactive wastes are categorized into very low level wastes, low level wastes, intermediate level wastes and high level wastes. Very low level wastes contain radioactive material at concentrations accepted not to be harmful to human population and the surrounding environment, main components are materials of: concrete, plaster, bricks, metals, valves and piping produced during operations, some food processing industries chemical industries and industries dealing in steel also produce this levels because of the natural radioactivity in the manufacturing process (Nikitin, Andrews & Holt, 2009, pp112- 167). Low level wastes are mainly generated from hospitals, nuclear fuel cycles and industries, they include: clothing, filters, papers and rags that mostly contains radioactivity with short lifes.They can be buried at shallow level, they doesn’t require shielding during handling and transportation. The wastes are compacted and incinerated before getting disposed. Low level wastes can comprise 90% volume but only 1% of the radioactivity of all radioactive waste. Intermediate level waste contain higher amounts of radioactivity, mainly comprise resins chemical sludge, metal fuel claddings and contaminated materials from reactor decommissioning.in handling these wastes the smaller once and those non solids can be solidified in concrete or bitumen to dispose, some of the intermediate level wastes requires shielding.7% of the intermediate level ...Show more

Summary

The nuclear power generation and other applications of nuclear fission and corresponding nuclear technology including the researches in the fields of medicine generates radioactive wastes as byproducts The wastes that results from nuclear fuels are not necessarily hazardous or…

The Benefits and Dangers of Nuclear Energy
The search of alternate energy source is revolving around solar energy and nuclear energy. Even though solar energy is renewable in nature, feasible technologies to convert it into useful energy forms are still not developed properly. On the other hand, the technology for the exploitation of nuclear energy is well developed.

Nuclear Technology vs Nuclear Weapons
This paper will attempt to answer the question of whether the concerns of the critics are founded. It will also try to show whether proponents are honest when they say that it is the safest and green energy to use. This report will also explore whether radioactive waste is a permanent problem or can it be solved.

Environmental Issues
Amongst the sources of organic matter used in bio-fuel production includes starch; sugary plants for instance corn and sugarcane; vegetable oils and animal fats; wood, algae and organic waste amongst many others. Bio-fuels has been an area of environmental concern as it has been sharply linked with rising food prices, drawing mixed reactions from different scholars.

Nuclear Program of North Korea
Consequently, it would be favorable for the United States if they made a paradigm shift in tackling this problem by negotiating with North Koreans. Ever since the mid twentieth century, North Korea has been engaging in nuclear development. There are two major reasons why this country may have chosen to take on such a venture.

How to Stop Nuclear Terrorism
Today WMDs are nuclear, biological, or chemical weapons-frequently referred to collectively as NBC weapons." Nuclear weapon is a device whose explosion causes massive release of energy by splitting the atoms of heavy elements ( fission) such as uranium or plutonium or fusion of lighter Hydrogen atoms.

Politics International Security Why did North Korea aquire Nuclear Weapns
A question may be brought to light regarding this topic: is there a resounding confession or admission by North Korea that indeed it has in its position weapons or nuclear bombs that can make it aligned with other nuclear-powered states Is there verifiable evidence of nuclear bombs, the one that could be carried by missiles and be fired to as far as the United States, if indeed there is an admission or confession This is important in our study because - as will be explained later - nuclear-powered states such as the United States, will use their power (leverage) to stop a state, such as North Korea, that is still in the process of possessing, or rumored to be processing, nuclear weapons.
