What are some disadvanatges of nuclear fusion energy?


Quick Answer

Some disadvantages of nuclear fusion energy include high costs of production, a long period of planning and development, the raw material is scarce, the risk to national security and risk of radiation. Nuclear fusion also emits a lot of heat energy that may be difficult to contain.

Full Answer

Some advantages associated with nuclear fusion include high power production and less carbon emission. There are also several disadvantages to this form of power generation as detailed below.

Risk of accidents

When certain accidents happen within a nuclear power generation plant, risks such as radiation are likely to occur. Radiation may cause adverse effects on humans, animals and the environment.


The duration of time taken to plan and develop a nuclear plant is quite long. In most cases it takes between 10 to 30 years to plan and complete a nuclear fusion energy plant.

High costs

The amount of money that goes into the development of a nuclear plant is high. Most countries are therefore unable to build nuclear plants and are forced to rely on other forms of power generation.

Raw materials

The raw materials used in nuclear fusion are fairly scarce and can only be found in certain countries. This means other countries must rely on those with the raw materials for nuclear power generation.
