–on the Canadian Coalition for Nuclear Responsibilityʼs website at .ccnr . The moment of explosion (or disintegration) is when radioactive fission products are dangerous. “It can cause a wide variety of illnesses . . . but the damage generally ...
Why is cracking an important technological process? What are shims in an NMR spectrometer and what is their purpose? Why does the hydrogen bomb require a primary fission reaction? a) How does nuclear magnetic resonance imaging allow us to see inside human bodies? b) In what other ways do yo...
Robert Oppenheimer (1904-67) hired and headed a group of leading scientists to harness the discovery of nuclear fission during the Second World War. The other is about Oppenheimer's downfall, which took place a decade later, when he lost his national-security clearance. In the first thread, ...
The commercial nuclear power plants that exist today generate electricity through nuclear fission reactions. In these reactions, heavier atoms (often uranium-235) are split into smaller atoms. A small amount of mass is converted to energy in this process and this energy is used...
Among the reasons usually given against nuclear fission energy are that it is: (a) unsustainable; (b) uneconomic; (c) unsafe and (d) has links to proliferation of nuclear weapons. Below each of these key concerns is addressed. Two important questions that need to be asked are: Is nuclear...
but maybe in exchange for this missing 2 dollars, i get a whole bunch of energy. that might be ok. this is exactly what happens with nuclear fission (fission means to break apart). if you looked at an atom, you would find it has three things: electrons, protons, and neutrons (ok, ...
radioactive waste which has to be safety stored, effectively indefinitely. Nuclear fusion effectively makes use of the same energy source that fuels the Sun and other stars, and does not produce the radioactivity and nuclear waste that is the by-product of current nuclear fission power generation...
The nuclear weapons register - a good idea whose time has come Transparency in nuclear arms is an important measure for world security, strengthening the nuclear nonproliferation regime and preparing the ground for nuclear disarmament. In fact, significantly enhanced information about the nuclear we.....
This little equation is central to the theory of special relativity, and also explains how nuclear fusion and fission can generate energy. Who said E = mc^2? In a famous paper written in 1905, Albert Einstein discovered an equality between mass and energy. He found that the conservation of...
3. The Challenge of Managing Nuclear Waste Perhaps one of the most alarming aspects of nuclear energy is the management of nuclear waste. Nuclear waste remains hazardous for thousands of years, and there are no viable long-term solutions for its safe storage. A small country like Sr...
