WebSep 11, 2013 · Similarly, nuclear fission requires high energy or a large mass of heavy, radioactive elements. For this reason, significant nuclear fission only occurs in supernovas, in nuclear fission bombs, in nuclear fission reactors, in cosmic ray impacts, in particle accelerators, and in a few natural ore deposits. WebDisadvantages of Nuclear Fission. Despite its advantages, nuclear fission also has some disadvantages. These include: • Nuclear fission produces radioactive waste, which must be disposed of safely and securely. • Nuclear reactors can be dangerous if not operated properly. If an accident occurs, the radioactive materials can cause serious ... WebApr 7, 2024 · Also, to better answer the question about time. Plutonium does not occur naturally, so the only way to get it is through a process like that DTruitt described above. This means any plutonium weapon will take longer to build and develop than a uranium one. Nuclear tests are also almost impossible to hide. incorrect patio sand jobs
