Nuclear Energy is a Domestic

Source of Energy


PWRs keep water under

pressure so that it heats,

but does not boil.

Most of the radioactivity

stays in the reactor area.

The Pressurized Water

Reactor (PWR)

The Boiling Water

Reactor (BWR)

BWRs actually boil the water.

• AFR-100 is a sodium fast reactor of the Small Modular

Reactor (SMR) design; developed to expand the options

for nuclear power and its application

• Small size of SMRs makes them suitable to small

electric grids so they are a good option for locations that

cannot accommodate large-scale plants

• Modular construction process would make them more

affordable by reducing capital costs and construction

times

• Transportable from pre-licensed factory

• Adopts innovative technologies and advanced materials

Refueling and wet storage

Refueling Wet storage

Each fuel assembly will stay in reactor in use for about 6 years. But refueling occurs by

approximately every 12 or 18 months, and only about 1/3 of fuels are replaced. They are

called spent fuels although about 96% of original fuel is still not used.


Fuel dry storage

•Spent fuel must be cooled down in fuel pools for >5 years

•They have option to be removed and loaded into dry storage canisters for dry storage.

•Regulations allow 60 years for dry storage.
