NAME
= name
TYPE
= type
SHAPE
= shape
NSLAB
= nslab
CHRLEN
= chrlen
the optional user-selected name for the structure. The name may have up to
eight characters. Note that, although the name is optional within CONTAIN,
it is used in POSTCON postprocessing, as discussed in Chapter 16.
the name of the type of structure, which may be either ROOF, WALL, or
FLOOR. These names refer to the orientation of the structure inner surface.
the name of the shape of the structure, which may be either SLAB,
CYLINDER, or SPHERE. See the discussion above for the actual shapes
invoked by these names.
the number of nodes in the structure. The number must be less than or equal
to “mxslab,” defined in the cell CONTROL block.
the characteristic length of the structure to be used in heat transfer
correlations. If the ADJUSTCL keyword is given with respect to a
submergible structure, an interpolated value depending on the submergence
is the actual length used in the heat transfer correlations, and “chrlen”
becomes the asymptotic value used when the pool surface level is at the top
or bottom of the cell, or both. (m)
ADJUSTCL a keyword to interpolate the characteristic length of a submergible structure
according to its submergence, as discussed in Section 10.1.1.5. In this option
the value of “chrlen” specified by the user becomes an asymptotic
characteristic length used when the pool level is at either the top or bottom
of the cell, or both. Note that continuity requires that “chrlen” be less than or
equal to a maximum value, which is determined by structure antior cell
dimensions. For a FLOOR slab, for example, this maximum value is the
distance between the floor top surface and the top of the cell. If “chrlen”
exceeds this maximum and the ADJUSTCL option is invoked, the code will
abort. The minimum value used for the interpolated characteristic length is
0.001 m.
SLAREA
= slarea
SLHITE
= slhite
SLELEV
= slelev
the area of a slab structure. (m*)
the height (vertical extent) of a slab structure of type WALL. This height is
used to calculate the submergence of the structure in a cell with a pool. (m)
the absolute elevation of the center of volume of a slab structure, to be used
in calculating the submergence of the structure in a cell with a pool. By
default the structure is assumed to be in contact only with the gas. For
connected structures, this elevation should correspond to the center of volume
of the appropriate individual structure, not the combined structures. (m)
