Nuclear data needs for decommissioning and design of nuclear facilities 05/2008; DOI: 10.1051/ndata:07429


Design and decommissioning of large-scale nuclear facilities is nowadays a high-interest activity for the nuclear community. Nuclear data have an important role in R&D studies for accelerator-based applications and decommissioning of nuclear facilities including nuclear reactors. Most of these studies use simulations to predict activity levels and dose rates, to design shielding components, etc. The different data libraries and/or reaction models included in the transport codes are essential for these calculations. In this contribution we present several examples of the nuclear data usage for this type of applications. We show the importance of a correct use of nuclear data and reaction models for the accuracy of the results obtained by simulations.

    ABSTRACT: We are developing a heavy ion transport Monte Carlo code which can treat the fragments produced by heavy ion reactions. For this purpose, we planned to combine the two codes, the one is the HIC or ISABEL code, to calculate the heavy ion nuclear reaction cross section and the other is the hadron transport Monte Carlo code, HETC-3STEP. First, we investigated the calculational accuracy of the HIC and ISABEL codes by comparing the calculated results with the experimental data. The ISABEL gives better agreement with the experimental data than the HIC. For easier handling we first coupled the HIC code with the HETC-3STEP code for developing the heavy ion transport Monte Carlo code. We also made a simple version of a heavy ion transport Monte Carlo code for limited geometry using the HIC code. The results calculated with this version of the code were compared with the experimental data. We are trying to couple the ISABEL code with the HETC-3STEP code.
