[en] This report describes the procedures and methods to carry out the VANDAL (Variability Analysis of Disposal Alternatives) code, which is a probabilistic safety assessment computer program for low- and intermediate-level radioactive waste disposal facilities, and to analyze the outputs. Originally, the VANDAL was developed in the United Kingdom for the regulatory evaluation of disposal safety. Through its research project 'Development of Regulatory Technology for Radioactive Waste', the KINS has made some efforts to adapt this code to the Korean circumstances. This report also includes the corresponding results in terms of input and output management. This report was prepared as a practical guidance which is applicable to case studies and independent regulatory evaluations related to safety assessment of the low- and intermediate-level radioactive waste repository. Therefore, it is desirable that in performing the related activities, the KINS staff follow the procedures and methods presented here. This guidance may provide a consistency in the VANDAL run and the corresponding output interpretation and contribute to the overall reliability and the quality assurance of the safety evaluations
