There is much discussion about small modular reactors for the future? What are their advantages and disadvantages?

Solution

One of the chief selling points for SMRs is that they are supposed to be safer than current reactor designs. However, their safety advantages are not as straightforward as some proponents suggest.

ADVANTAGES:

Another advantage of modular design is that some SMRs are small enough to be installed below ground. That is cheaper, faster to construct and less invasive than building a reinforced concrete containment dome. There is also the point that putting a reactor in the ground makes it less vulnerable to earthquakes. Underground installations make modular reactors easier to secure and install in a much smaller footprint. This makes SMRs particularly attractive to military customers who need to build power plants for bases quickly. Underground installation also enhances security with fewer sophisticated systems needed, which also helps bring down costs

DISADVANTAGES:

the reactor with sufficient strength and volume to
withstand the forces generated by overpressurization
and hydrogen explosions in severe accidents.

SMRs
therefore must rely on means to prevent hydrogen
from reaching explosive concentrations.
