Attend our two paper presentations in partnership with the CEA, Brenk, Energorisk and LNE and discover innovative technics of contamination characterization that arise from a new methodology developed and validated in the framework of the European project INSIDER H2020.
In the meantime, visit our team at booth #1 and ask for your demo of Kartotrak, our software solution for contaminated site and soil characterization. You'll discover an innovative new workflow for contaminated volume quantification and the rapid delivery of excavation plans.
Robustness of statistical and geostatistical approaches for the radiological characterization of soils beneath a building
by Yvon Desnoyers from Geovariances and Nathalie Pérot from the CEA, DES, IRESNE, DER, SESI
This paper is dedicated to the radiological characterization of contaminated soils in the context of post-incidental remediation of a site. For this use case, the constraint environment came from the difficulty to collect samples beneath a building on the one hand and the fact that samples were collected in the past with no possibility for additional samples. Two evaluation objectives were pursued: global estimates of total activity (source term) and local categorization of volumes according to a radiological threshold for waste acceptance. Several statistical and geostatistical approaches are compared with a specific focus on uncertainty quantification.
Initial nuclear state characterization in view of decommissioning: Statistical approach guideline and web tool
by S. Boden and B. Rogiers from SCK CEN, Y. Desnoyers from Geovariances , N. Pérot from the CEA , G. von Oertzen from Brenk, O. Sevbo from Energorisk, and S. ? from LNE
The complete initial characterization process can be rather complex when dismantling nuclear power plants or facilities. The paper outlines a new statistical approach guideline and a web tool to guide the expert in handling the problem definition and applying a strategy based on data analysis and sampling design. It also provides a return of experience from implementing the strategy in four use cases: a liquid waste storage facility, a biological shield from a pressurized water reactor, post-accidental site remediation, and graphite from a gas graphite reactor.
