What is the place where controlled nuclear fission reactions take place?
The place where controlled nuclear fission reactions take place is called a nuclear reactor. In a nuclear reactor, uranium atoms are split in a controlled manner to produce heat energy, which is used to generate electricity.
What is the function of reflector and reactor core?
The reflector in a nuclear reactor helps to reflect neutrons back into the reactor core, increasing the chances of nuclear reactions occurring. The reactor core is where the nuclear reactions take place, generating heat that is used to produce electricity.
When and where did the first controlled nuclear reactions take place?
Chicago, 1942
What are Controlled nuclear chain reactions?
Those reactions that take place in functioning nuclear reactors (i.e not Chernobyl or Fukushima when the accidents happened).
The reactions that produce molecular oxygen (O2) take place in?
The reactions that produce molecular oxygen (O2) take place in the light-dependent reactions of photosynthesis, specifically in the thylakoid membranes of the chloroplasts. Here, water molecules are split through a process called photolysis, releasing oxygen as a byproduct.
What type of reaction take place in a nuclear reactor?
Nuclear fission, not to be confused with fusion.
How are nuclear reactions that take place in the sun different from the nuclear reactions that take place in a nuclear reactor?
sun, fusion of hydrogen nuclei making helium nuclei (not radioactive)nuclear reactor, fission of uranium nuclei making a wide variety of different fission product isotopes having mass numbers from 72 to 161 (all very radioactive)
What part of the nuclear powerplant does the chain reaction occur?
The chain reaction in a nuclear power plant occurs in the reactor core, where nuclear fission reactions take place. Heat generated from these reactions is used to produce steam, which then drives turbines to generate electricity.
Where do nuclear fission reactions often take place, and what are the key factors that contribute to their occurrence in that location?
Nuclear fission reactions often take place in nuclear reactors. The key factors that contribute to their occurrence in that location include the presence of fissile materials such as uranium-235 or plutonium-239, control rods to regulate the reaction, and a moderator to slow down the neutrons.
Where does the Light (dependent) reaction take place?
The light dependent reaction take place in the thylakoid of the chloroplast
Were chemcal reaction takes place cell organelles?
Chemical reactions take place in various cell organelles. For example, in mitochondria, reactions like cellular respiration occur to produce energy. In the nucleus, reactions like DNA replication and transcription occur. And in the cytoplasm, reactions like protein synthesis take place.
Where do astrophysical neutrinos come from?
They originate from nuclear reactions, such as those that take place in a star, when cosmic rays hit atoms and in supernovae.
