The number of fuel assemblies that enter the inner capsule varies depending on the type of fuel, among other factors.
A system of concentric glass macrocapsules was used to envelope the expansive minerals (outer capsule) and water (inner capsule).
Hydrous glasses synthesized at high pressure as a starting material was inserted into the inner capsule and weighed, then welded on the other end and weighed.
It is worth introducing here that HM buffer in the outer capsule fix the chemical potential of hydrogen in a pure H2O vapor, but the inner capsule contains a mixed vapor; as a consequence the oxygen fugacity in the inner capsule is intrinsically lower than in the outer capsule (see details in Poli et al., 2009).
The method used double-layered capsules in order to create suitable hydrothermal conditions; the inner capsule encapsulated the coating materials and a Ti substrate, while the outer capsule was subjected to isostatic pressing under the hydrothermal conditions.

The actual value of the oxygen fugacity in the inner capsule is then fixed either by redox equilibria, or by a fixed C/O ratio, or by the occurrence of graphite/diamond, however not observed here.
A negligible water loss from the inner capsule to the surrounding olivine was measured by ion probe in sample CD2H3 (238 ± 1 ppm H2O loss, compared with the 2.6 wt.% dissolved in the melt).
PCR amplification of vole-specific gene products from the inner capsule confirmed that it was derived from the injected vole cells (data not shown).
And then capsules entrapped different PEG were placed into deionized water for 500 mins to determine the diffusion of PEG from inner capsule.
