INTEG is a computer program which integrates values computed by various other programs to provide the long-term consequences of the groundwater pathway. inventory, for the travel through the vadose zone, for the travel through the unconfined aquifer, and for exposure effects.

Values are taken from codes producing values for the initial

A major outcome of environmental analyses is the contamination concentrations and their resultant effects on human beings. These outcomes are not calculated in a single step. performed which are then combined to find the contaminant concentration and resultant dose. The information needed is:

Instead a series of calculations are

The normalized spatially averaged contaminant flux as a function of time [ i(t)] at the bottom of the unsaturated (or vadose) zone. The flux is normalized so that the integral over time is unity.

The area [A] over which the contaminant flux is averaged. Normally, this is taken as the area of the disposal facility.

The water flux [r] entering the unconfined aquifer from the vadose zone (i . e . , the recharge rate).

The ratio [R] of the contaminant concentration (amount of contaminant per volume of water) in the vadose zone and at the point of interest in the unconfined aquifer.

The dose factor [DFi] which converts contaminant concentration into the dose or risk desired.

than about 20 half- lives). However, for such conditions the contribution of these nuclides is very small compared to nuclides nearer the parent in the chain.

Various elements in a decay chain will be retarded by different amounts during their travel in the vadose zone. vadose zone transport codes simulate travel only by the K, value of a given layer and not by species which could change as a function of time, approximations must be made. nuclide. Thus the user can choose to assign the value based on the initial nuclide in the chain or on its own value. Large differences can occur when parent and daughter have significantly different K, values (for example, 237Np and 233U).

Thus for pratical problems, this limitation is not important.

Because the current versions of the

PORCON

PORFLOW (ACRi 1994) is one of the water flow and contaminant transport codes used in long-term performance assessment at Westinghouse Hanford. PORFLOW can only calculate results for 4 Kd values at a time. provide greater flexibility in the number of Kd values and to make the vadose zone input file easier to read, a program entitled PORCON was written. reads a series of "fort.35" files produced by various PORFLOW and produces an output which has the contaminant flux density entering the aquifer. various PORFLOW runs have different time steps, then an union of time steps is used with the missing flux values obtained by linear interpolation.
