Dose rates in the ABWR upper drywell for a dropped fuel bundle accident
- Oak Ridge National Lab., TN (United States)
QADS is a module that performs multidimensional point-kernel estimation of gamma transport through practically any type of shielding materials using a simplified input scheme that follows the general input philosophy of the SCALE shielding sequences. 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 SASI. 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.
