    Abstract

    This paper presents radiation shielding calculations performed using the Serpent 2 Monte Carlo code for a radioactive sample storage vault located at VTT's Center for Nuclear Safety (CNS). The computational sequence is divided into weight-window generation using an automated built-in global variance reduction scheme, followed by the calculation of radiation fields on the outer walls of the storage vault and dose rates at selected detector positions. The results are compared to experimental measurements. The purpose of the study is to evaluate the capability of Serpent for performing shielding calculations at the CNS. The feasibility of the variance reduction scheme is demonstrated. There are considerable differences between the calculated and experimental results, which can be attributed to modeling approximations and limitation in the personal electronic dosimeters used for the experimental measurements.
