QADS is the control module designed to perform three-dimensional point-kernel estimation of gamma transport using QAD-CGGP. QADS was designed to capture the flexibility and power of the QAD technique for problems amenable to point-kernel solution while allowing for an easy-to-use input interface. The QADS module is called via the SCALE driver and preprocesses the actual input for the QAD-CGGP code. The driver then calls and executes QAD-CGGP automatically. The SCALE standard composition library is used to allow simplified input of materials. The problem geometry is coded using the well-known MORSE combinatorial geometry package. Finally, the dose portion of the input follows the XSDOSE input data format in SAS1. The combined use of the SCALE standard compositions and free-form input with the multidimensional geometry capabilities and generally short running time of point-kernel techniques produces a very powerful procedure for shielding analysis of a wide variety of problems.
