Viewpoint: Yes, radiation waste from fission reactors can be safely stored using existing technical expertise and drawing on the experience of test facilities that are already in operation. Viewpoint: No, radiation waste from fission reactors cannot be...

Nuclear waste is radioactive material that has no immediate use. In the United States nuclear waste generally is divided into two main categories: high-level nuclear waste (HLW) and low-level radioactive waste (LLW). Two less common categories are...

Disposal of nuclear waste has been a contentious issue both in the United States and elsewhere in the world. Difficult questions are involved, including: (1) where should one put the waste? (2) How long must such waste be stored before it does not pose...

Radioactive waste (or nuclear waste) is a material deemed no longer useful that has been contaminated by or contains radionuclides. Radionuclides are unstable atoms of an element that decay, or disintegrate spontaneously, emitting energy in the form of...

Radioactive pollution can be defined as the release of radioactive substances or high-energy particles into the air, water, or earth as a result of human activity, either by accident or by design. The sources of such waste include: 1) nuclear weapon...

Radioactive waste materials are produced as by-products of research, nuclear power generation, and nuclear weapons manufacture. Radioactive waste is classified by the U.S. government into five groups: high-level, transuranic (chemical elements heavier...

In the 1960s, nuclear power gained popularity as a means of producing power for civilian use. During the next two decades, several nuclear power plants were built, but there was little consensus about how to best dispose of radioactive waste. Waste...

Radioactive waste is what remains after the use or production of radioactive materials. Modern society uses a variety of products and services that depend on radioactive materials. Uses include the production of household smoke alarms, gauges and...

Radioactive waste is the "garbage" left as a result of the use of nuclear materials by human societies. Such waste can be categorized as low-level, intermediate-level, or high-level waste. The term transuranic waste is also used to...

Various aspects of nuclear energy research, nuclear fuel processing, and weapons production took place in every republic of the former Soviet Union. In the Central Asian republics, areas of radioactive contamination are widespread. By far the worst...

A solid, liquid or gaseous material of negligible economic value containing radionuclides in excess of threshold values. High level waste (HEW), produced in the first cycle of reprocessing spent nuclear fuel is highly radioactive. Intermediate level...

Radioactive wastes are waste types containing radioactive chemical elements that do not have a practical purpose. They are sometimes the products of nuclear processes, such as nuclear fission. However, other industries not directly connected to the...
