The objective of INSIDER work package 3 WP 3 is to draft a sampling guide for initial nuclear site characterization in constrained environments based on a statistical approach. In this paper deliverable D is presented for WP 3 where the strategy developed in deliverables D to D is applied to the first of three reference use cases representative of existing decommissioning scenarios. The present discussion focuses on use case 1 UC1 the liquid waste storage facility at the JRC site of Ispra Italy . The proposed characterization strategy developed in D is applied in a step by step approach to analyse the pre-existing information obtained through the use of a pre-sampling questionnaire and to utilise the available inputs towards the development of a sampling plan sufficient for allowing radiological characterization. The proposed sampling plan follows a three-step approach . determination of possible elevation in activity concentration by non-destructive testing biased sampling of layers identified and finally unbiased sampling after mixing of tank contents. 1 Introduction Pre-characterisation questionnaire Background A pre-characterisation questionnaire was used to deter- mine the historical background scope purpose and end The facility selected for the case study UC1 is the liquid points of the characterisation. This was sent to the Ispra
