What is the direct function of energy released from the nuclear chain reaction in a nuclear power plant quizlet?

What is the direct function of the energy released from the nuclear chain reaction in nuclear power plant?

The energy released from this chain reaction creates heat. The heat created by nuclear fission warms the reactor’s cooling agent. A cooling agent is usually water, but some nuclear reactors use liquid metal or molten salt. The cooling agent, heated by nuclear fission, produces steam.

What is the purpose of the chain reaction in a nuclear power plant quizlet?

When the control rods in a reactor core are completely lowered between the fuel rods, fission is prevented, and it shuts down. Metal fuel rods containing uranium pellets are bombarded with neutrons. A chain reaction results that releases energy and produces more neutrons.

What are the advantages and disadvantages of nuclear reactors?

Advantages and disadvantages of nuclear power stations

Advantages Disadvantages
Very low fuel costs. Large-scale accidents can be catastrophic.
Low fuel quantity reduces mining and transportation effects on environment. Public perception of nuclear power is negative.

What are the major disadvantages of nuclear power quizlet?

Nuclear energy produces no greenhouse gases, does not contribute to acid deposition, and is highly concentrated. Disadvantages of nuclear energy include the high cost of building a power plant and safety concerns about the operation of the plant and disposal of spent fuel rods.

In what part of the nuclear power plant does the chain reaction occur quizlet?

Terms in this set (15)

A chain reaction occurs in a nuclear reactor when each fission event causes further fission events. So the additional neutrons released in fission may also hit other uranium or plutonium nuclei and cause them to split.

Why is nuclear energy bad?

Nuclear energy produces radioactive waste

A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years.

What are two ways to release nuclear energy?

Nuclear energy is released from an atom through one of two processes: nuclear fusion or nuclear fission.
