vacancies that will be filled with
heavier atoms from the remaining
radioisotopes.
prevent formation of water vapor.
Thermodynamically, this newly
formed water vapor will make the
transition into liquid water droplets
attached on the metal containers
surface (internally and externally).
At elevated temperatures and
pressure for a significant period of
several hundred years, the semisoftened/ semi-melted amorphous
boron silicate glass will undergo a
partial or complete transition into
a complex crystalline lattice formation. This transition will completely
alter the inner limited space of
the encapsulating metal container.
The density difference between the
amorphous glass (2.5 g/cc) and
metal silicates (from 3.1 g/cc to
7.2 g/cc) will result in an expansion
increase (neglecting the temperature expansion) from 1.24 times to
2.84 times the original volumes.
The designed ventilation and water
drainage systems of the deep geological repository are assumed to
accommodate all external water
condensation in the tunnel. The
concern is for all water condenses / vapors inside the steel containers and large metal canisters.
This water will react with metal
silicates and make the transition
to complexes of Calcium, Sodium,
Potassium and Barium Alumina sili 6FW2
