Code Manual for CONTAIN 2.0 - Federation of American Scientists

(a) Atmospheric Masses: MATERIAL=N2
(b) Aerosol Deposition: AEROSOL=NA20 LOCATION=FLOOR
(c)Fission Product Mass: FPNAME=CS 137 HOST AEROSOL NA20
(d) Airborne Aerosol Mass: AEROSOL=NA20 SECTION SUM 1,20
(e) Lower Cell Masses: MATERIAL=K20 LAYER=3 NODE=l
(f) Pool Boil Information: TYPE=BOILMASS
In example (a), the item keyword is MATERIAL, and N2 is the value (an
error message would be written to the PERR file followed by a code abort if
N2 is not in the material list of the CONTAIN run). In example (b), there are
two sets of item keywords and values, each which have the same format as
the first example. In example (c), the HOST item keyword (IKEY1) is
followed by the AEROSOL item keyword (IKEY2) prior to the specification
of the host name. This is necessary since aerosols, structure surfaces, and
extra materials may be fission-product hosts, each of which have names. In
example (d), the fust item keyword set is just as in the first two examples,
and the second item keyword set is similar to the third example. However,
this example is further complicated by the fact that both “valuel” and
“value2” parameters follow the SECTION and SUM item keywords.
Example (e) is interesting because there are three item keywords and values,
each of which is needed to define the desired table column. The item
keyword TYPE used in example (f) is reserved for flags that have various
types of data that cannot be categorized by a more descriptive term. In some
of these cases, the values are the actual names of the variables in the
CONTAIN code.
A full list of the item keywords and acceptable values is provided in Table
16-1 for each flag. If an item keyword/value pair is omitted, the fwst data
value in the record is always assumed. If an item keyword appeam more than
once in a curve definition, all but the last one will be ignored. Note that some
item keywords have order dependencies which should be acknowledged.
Example (e) above is an example of an order-dependent group of item
keywords. In this example, the layer number must be given before the node
number because each layer has its own number of nodes. Such dependent
item keywords are designated in Table 16-1 through use of indentation levels.
ENDCURVE keyword that terminates the definition of a curve. Each curve in a TDB
normally begins with the CELL keyword, and must end with the
ENDCURVE keyword. A multiple column table is created by including
several curves in a TDB. The ENDCURVE keyword is mandatory.
ENDFLAG keyword that terminates the TDB. Following this, another TDB can be
specified, or if this is the last TDB, the MIX block or the EOF marker may
follow.
