a keyword to specify that source table input follows.<br />

the number <strong>of</strong> fission product source tables to be specified. This number<br />

should agree with the value specified in the cell CONTROL block.<br />

the name <strong>of</strong> the fission product declared in the global FISSION block.<br />

the number <strong>of</strong> points in the fission product source table. The value <strong>of</strong><br />

“nspsfp” in the cell CONTROL block must be greater than or equal to “nf.”<br />

required keyword to specify the host number associated with the fission<br />

product in the table. Specify a number between 2 and 1 + “nac” which<br />

corresponds to the aerosol host.<br />

the number <strong>of</strong> the fission product chain that is to receive the “<strong>of</strong>p” mass. This<br />

should be given if “<strong>of</strong>p” appears more than once in the linear chain<br />

decomposition.<br />

a keyword to specify SRV gas and condensable vapor sources. The keywords<br />

and values associated with these sources but not discussed below are<br />

discussed in Sections 14.3.1.2, Upper Cell Atmosphere Initial Conditions and<br />

Sources, and 14.4.1, Source Table Input. (The <strong>for</strong>mer section describes<br />

atmosphere sources that enter the atmosphere directly without equilibrating<br />

with the pool.)<br />

a keyword to specify that source table input follows,<br />

the number <strong>of</strong> gas source tables to be specified. This number should agree<br />

with the value specified in the cell CONTROL block.<br />

the name <strong>of</strong> a gas or the condensable vapor. This material must be among the<br />

materials specified after either the COMPOUND or USERDEF keywords in<br />

the global MATERIAL input block.<br />

nat the number <strong>of</strong> points in the gas source table. The value <strong>of</strong> “nspsat” defined<br />

in the cell CONTROL block must be greater than or equal to “nat.”<br />

An example <strong>of</strong> the SRVSOR input is given below. The elevation <strong>of</strong> the discharge point is one meter<br />

above pool bottom. The aerosol sources, in addition to the usual time and mass rate specifications,<br />

use the optional keywords <strong>for</strong> specifying size distribution parameters, AMEAN and AVAR. The<br />

SCRUB aerosol scrubbing option, by default, is in effect, with default parameters. The U02 aerosol<br />

is intended to be the first aerosol component in this example, and the fission product LA203 is<br />

associated with this component through the HOST=2 specification. The control parameters that need<br />

to be specified in the cell level CONTROL block to accommodate the tables are “nsosat’’=2,<br />

“nspsat’’=4, “nsosae “=1, “nspsae’’=4, “nsosfp’’=l, and “nspsfp’’=4.<br />
