[en] This is a partial result of the research project 'Development of Regulatory Technology for Radioactive Waste', and provides safety verification methodology on the interim dry storage of spent nuclear fuel generated from CANDU reactors. The main objective of this report is to support safety reviewers to perform systematic and detailed safety verification of the CANDU SNUFI-D (CANDU Spent NUclear Fuel Interim storage - Dry type) to be proposed by domestic applicant(s) in the near future. With this regard, related safety factors were categorized into three parts (i.e. verification of radiological safety and non-radiological safety, and accident analysis), and then basic considerations and detailed verification methodology were provided for each part. In addition, preliminary case-studies performed based upon the proposed verification methodology were also provided, so as to maximize the applicability of this report. In order to make the methodology applicable to various types of storage systems, design-specific consideration was excluded as possible

[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
