USCD1150 UTAP-3.

1. NAME OR DESIGNATION OF PROGRAM:  UTAP-3.

3. DESCRIPTION OF PROGRAM OR FUNCTION

UTAP carries out probabilistic  analyses of the behaviour and environmental effects of uranium mill  tailings, following close-out of milling operations. The models have been designed to allow predictions to be made for distances up to 50 kilometers in all directions from the tailings area. The models include features which include the ability to incorporate different  receptors and site characteristics and to deal with input parameters which vary with time.

4. METHOD OF SOLUTION

UTAP is composed of a number of modules. These  may be classified as either component or control modules. Component  modules (or models) are the programs directly concerned with the smulation of a uranium tailings physical system; that is the computer implementation of the mathematical models representing the  uranium tailings pile and surrounding environment. Control modules provide the infrastructure for probabilistic analysis using the component modules. These functions include probabilistic sampling of input parameters such as constant, normal, log-normal, uniform, log-uniform, triangular, Weibull, Beta, arbitrary and correlated. The sampling method used is straight Monte Carlo. The radionuclides  modelled are : natural uranium, total thorium, radium-226, radon-222 and lead-210. The pH of the reference uranium tailings site and a chained river-lake system are also modelled. For the afore- mentioned radionuclides the following pathways of dose to the receptors modelled: water consumption, fish consumption, radon inhalation, dust inhalation, vegetable consumption, animal produce consumption and groundshine.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM:  The maximum number of steps through time allowed is 300.

6. TYPICAL RUNNING TIME:

NEA-DB executed the test case included in this package  on an IBM PC/AT in 3 minutes 25 seconds.

7. UNUSUAL FEATURES OF THE PROGRAM:

8. RELATED AND AUXILIARY PROGRAMS

Two auxiliary programs (BIN, CBAND) are included for the calculation of the confidence bands estimates on user selected data.
