A Simple Design Code for Duct-Streaming Radiations

The DUCT-III code is a simple design code to calculate duct-streaming radiations in nuclear facilities by using a semi-empirical formula based on an albedo analytical method. This code is applicable to designs of penetrations in nuclear power plants, fusion reactor facilities, accelerator facilities, and so on, because albedo data for γ-rays up to 10 MeV and neutrons up to 3 GeV are implemented in it. There are two versions of this code, the UNIX version runs on workstations and the Visual Basic version runs on Microsoft Excel 97*. The code package contains the Fortran source (or PC executable), data libraries, sample input and output data. In this report, an outline, additional functions of the DUCT-III code, and how to install and use it are described. *: Copyright (C) Microsoft Corporation.
