Radiological Analyses of Intermediate and Low Level Supercompacted Waste Drums by VQAD Code

QAD-CGGP is a member of a well-known family of point-kernel codes, developed by Los Alamos Scientific Laboratory, and is routinely used for engineering calculations of neutron and gamma ray penetration through various shield configurations. The original QAD-CGGP code geometrical source definition is limited on a single body as well as the buildup factor calculation which is limited on a single layer shield. In order to increase the possibilities of QAD-CGGP code by widening the code's application field a number of modifications have been performed in the past. Uniform multi-source option and shielding multi layer option have been introduced into the code [1, 2]. To finalize modifications of the code, we have decided to introduce a general multi-source option and to create a Graphical User Interface (GUI) as a response to modern software design guidelines. GUI provides a visual, user-friendly environment for QAD input and output creation and analyses. Testing of the Visual QAD-CGGP (VQAD) code has been conducted on intermediate and low level supercompacted waste drums. Radiation dose rate calculations have been performed for a single compacted waste drum as well as for the field of waste drums, i.e. the storage area. NPP Krško waste characterization has been taken as a reference one.
