Introduction

Nuclear fission is a process in which an atomic nucleus splits into two or more smaller nuclei, releasing a significant amount of energy in the process. This process is the basis for nuclear power generation, where a controlled nuclear fission reaction is used to produce steam, which then drives a turbine to generate electricity. In this article, we will explore the different types of nuclear fission reactions and identify which one takes place in a nuclear fission reactor.

What is Nuclear Fission?

Nuclear fission is a type of nuclear reaction in which an atomic nucleus splits into two or more smaller nuclei, along with the release of energy, neutrons, and gamma radiation. This process occurs when an atomic nucleus is struck by a high-energy neutron, causing it to become unstable and split into two or more smaller nuclei. The resulting nuclei are typically radioactive and can undergo further nuclear reactions.

Types of Nuclear Fission Reactions

There are several types of nuclear fission reactions, including:

Spontaneous fission: This type of fission occurs when an atomic nucleus splits without being struck by a high-energy neutron.
Induced fission: This type of fission occurs when an atomic nucleus is struck by a high-energy neutron, causing it to split.
Neutron-induced fission: This type of fission occurs when a high-energy neutron collides with an atomic nucleus, causing it to split.

Nuclear Fission in a Reactor

A nuclear fission reactor is a device that uses a controlled nuclear fission reaction to produce steam, which then drives a turbine to generate electricity. The reactor consists of a fuel assembly, a moderator, and a control rod. The fuel assembly contains fuel rods made of a fissile material, such as uranium-235 or plutonium-239. The moderator is a material that slows down the neutrons released by the fission reaction, allowing them to cause more fission reactions. The control rod is used to regulate the reaction by absorbing excess neutrons.

Which Reaction Takes Place in a Nuclear Fission Reactor?

To determine which reaction takes place in a nuclear fission reactor, we need to examine the options provided:

A. ${$ { }_6^{13} C +{ }_1^1 H \rightarrow{ }_7^{14} N$}$

B. ${$ { }_{94}^{239} Pu +{ }2^4 He \rightarrow{ }{96}^{242} Cm$}$

C. ${$ { }_{27}^{50} Co +{ }2^1 He \rightarrow{ }{29}^{53} Cu$}$

Option A: ${$ { }_6^{13} C +{ }_1^1 H \rightarrow{ }_7^{14} N$}$

This reaction is a type of nuclear reaction known as a proton-proton reaction. It involves the collision of a proton (hydrogen-1) with a carbon-13 nucleus, resulting in the formation of a nitrogen-14 nucleus. This reaction is not a fission reaction, as it does not involve the splitting of an atomic nucleus.

**Option B: ${$ { }_{94}^{239} Pu +{ }2^4 He \rightarrow{ }{96}^{242} Cm$}$**

This reaction involves the collision of a helium-4 nucleus with a plutonium-239 nucleus, resulting in the formation of a curium-242 nucleus. This reaction is a type of nuclear reaction known as a fusion reaction, where two or more atomic nuclei combine to form a single, heavier nucleus. This reaction is not a fission reaction, as it involves the combination of nuclei rather than their splitting.

**Option C: ${$ { }_{27}^{50} Co +{ }2^1 He \rightarrow{ }{29}^{53} Cu$}$**

This reaction involves the collision of a helium-4 nucleus with a cobalt-50 nucleus, resulting in the formation of a copper-53 nucleus. This reaction is a type of nuclear reaction known as a neutron-induced fission reaction, where a high-energy neutron collides with an atomic nucleus, causing it to split. This reaction is a fission reaction, as it involves the splitting of an atomic nucleus.

Conclusion

In conclusion, the reaction that takes place in a nuclear fission reactor is a neutron-induced fission reaction, where a high-energy neutron collides with an atomic nucleus, causing it to split. This reaction is represented by option C: ${$ { }_{27}^{50} Co +{ }2^1 He \rightarrow{ }{29}^{53} Cu$}$. This reaction is a type of nuclear fission reaction, where an atomic nucleus splits into two or more smaller nuclei, releasing a significant amount of energy in the process.
