5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM
Maxima of -
140 elements in 3-D region (including transition elements)
30 channel nodes
5 transition elements
1 cover gas space
28 connections to finite elements for each transition element
4 connections to channels for each transition element
200 time-steps saved in plot output array
In general, the following assumptions also apply -
A single water leak occurs instantaneously.
The chemical reaction is instantaneous.
All water reacts to form NA2O and H2 at 1800 degrees F.
The hydrogen bubble expands isothermally.
The sodium is incompressible.
The steam generator does not deform.
The analysis stops when the hydrogen bubble reaches a cover
gas space or completely fills a flow channel.
