Pressurized (light) water reactor

Primary heat transport: H2O - so-called light (normal) water

Recycled uranium

Extracted by reprocessing of spent uranium nuclear fuel

'Small' size

Electric output of between 10 MWe and 100 MWe

Kinetic neutron energy of 0.000…0.025 eV

Slow or cold neutron / moderated neutron spectrum

Thorium (Th)

Naturally-occurring, slightly radioactive metal, three times more abundant than uranium

Tristructural isotropic (nuclear fuel)

TRISO fuel assembly arrangement in hexagon form

Tristructural isotropic (nuclear fuel)

Consists of movable spherical elements of tennis-ball size called pebbles

Tristructural isotropic (nuclear fuel)

Fuel elements consisting of prismatic blocks

Uranium oxycarbide (UCO), uranium mononitride (UN) tristructural isotropic (TRISO) fuels

TRISO prismatic: consisting of prismatic blocks

Construction in progress in the shops of the suppliers, preparatory onsite work, construction of nuclear safety relevant elements, cold and hot functional tests

Uranium dioxide

Most often used uranium compound for fuel elements

Ceramic-metal fuel

Consist of ceramic fuel particles such as uranium dioxide (UO2) embedded in a metal matrix
