Nuclear radiation types of radioactive decay an unstable nucleus can decay by emitting an alpha particle a beta particle a gamma ray or in some cases a single neutron. Advantages and disadvantages of nuclear power stations generating electricity using nuclear reactors carries high risk but offers. An uncontrolled fission reaction is the basis of an atomic bomb.
Diagram showing the workings of a graphite moderated nuclear reactor controls rods left unchecked a chain reaction can result in the number of reactions occurring increasing over time with the risk that a reactor might become too hot and melt. In one of the fusion. Nuclear fusion reactions happen naturally in stars such as our sun.
Nuclear fusion is a process in which two relatively small nuclei join together to make one larger nucleus. The nuclei fuse together and energy is released. Nuclear fusion occurs when two small light nuclei join together to make one heavier nucleus.
Advantages and disadvantages of nuclear power stations generating electricity using nuclear reactors carries high risk but offers large rewards. Nuclear reactor diagram gcse geography shield the daughter products of the fission reaction are radioactive and can be a hazard. Is absorbed by a uranium nucleus typically uranium 235.
In a nuclear reactor a neutron. Nuclear fission is the form of energy used to generate electricity in nuclear power stations. In order to undergo nuclear fission a nucleus usually requires some energy which can be given by hitting the nucleus with a neutron.
Usually large unstable nuclei break up gradually by the process of radioactive decay but a small number including uranium 235 a naturally occuring isotope of uranium can break up in one big go a process known as nuclear fission. Learn about and revise nuclear fission nuclear fusion and how energy is released from these processes with gcse bitesize physics. This causes the nucleus to.
In a nuclear reactor a neutron is absorbed into a nucleus typically uranium 235.
Nuclear fission diagram gcse. Nuclear fission is the splitting of a large atomic nucleus into smaller nuclei.
Nuclear fission is the splitting of a large atomic nucleus into smaller nuclei.
