the keyword to begin specification <strong>of</strong> concrete outgassing parameters <strong>for</strong> the<br />

present structure. Other keywords may follow to select the amount <strong>of</strong><br />

outgassable water and C02 in the structure. Note that the concrete<br />

composition pararneters’’fco2,” “fh20b,” and “fh20e” may also be specified<br />

in the OUTGAS input block <strong>for</strong> those structures that have uni<strong>for</strong>m concrete<br />

composition. If the parameters specified in OUTGAS are satisfactory,<br />

CONCDATA need not be specified <strong>for</strong> a given structure.<br />

the evaporable water mass fraction, defined as <strong>for</strong> “fh20e,” except that<br />

“nslab” values are specified, one <strong>for</strong> each node in the structure.<br />

the bound water mass fraction, defined as <strong>for</strong> “fh20b,” except that the “nslab”<br />

values are specified, one <strong>for</strong> each node in the structure.<br />

the C02 mass fraction defined as <strong>for</strong> “fco2,” except that “nslab” values are<br />

specified, one <strong>for</strong> each node in the structure.<br />

the keyword to begin the specification <strong>of</strong> the inner surface boundary<br />

condition <strong>for</strong> a structure.<br />

the keyword to specify that the natural convection correlations given in<br />

Equations (10-24) through (10-26) from Reference Roh85 are to be used. No<br />

other input required.<br />

parameters to define N~u,C,l as in Equation (10-27). This keyword is optional<br />

but, if specified, it must be followed immediately by the four values “al,”<br />

“bl ,“ “cl ,“ and “dl ,“ in that order. These values correspond to the parameters<br />

al ... dl in Equation (10-27). Defaults: none.<br />

parameters to define N~u,CJas in Equation (10-27). This keyword is optional<br />

but, if specified, it must be followed immediately by the four values “a2,”<br />

“b2,” “c2,”and “d2,”in that order. These values correspond to the parameters<br />

~ ... dz in Equation (10-27). Defaults: none.<br />

the keyword to specify that the choice between NATCOR1 and NATCOR2<br />

is to be based upon the boundary layer stability criterion, with NATCOR1 to<br />

be used when the boundary layer density gradient is stabilizing and<br />

NATCOR2 when the gradient is destabilizing. If STBNCOR is applied to a<br />

structure <strong>of</strong> type WALL, the criterion will be applied as if it were type<br />

FLOOR.<br />

the keyword and value to speci~ that the two natural convection correlations<br />

are to be combined as in Equation (10-28). The keyword must be followed<br />

immediately by “xml ,“ the value <strong>of</strong> the exponent ml in Equation (10-28).<br />

“xml” >0 is required. Default: none.<br />
