www.oecd-nea.org Key Overall Findings Need for repository of information of innovations and knowledge of its existence (beyond access)

Sharing and collaboration across nations is important Innovation doesnt need to be costly or even technology driven Communicating uncertainty to stakeholders and negotiating acceptable levels of uncertainty is key Image Credit: WPTES workshop webpage: source: Matt Mellor, Createc, Autonomous and Intelligent Characterisation

www.oecd-nea.org Key Findings (Characterization)

Difficult to measure (DTM) isotopes is a challenge but innovations in detection of DTMs are available

Fast and reliable methods for concrete characterization is needed

Existing information sources can be leveraged and combined to inform decision-making (in a common data environment or soft and hard data combined in geostatistical analysis)

There are many purposes of characterization

Objectives for characterization need to be established to assist with planning and implementation Image Credit: WPTES workshop webpage source: https://www.chetec-infra.eu/ta/tna-labs/univie-vera/ from Thomas Braunroth, GRS, Measurement of Difficult-to-Measure Radionuclides in the Nuclear Environment and Recent Developments in Accelerator Mass Spectrometry (top); Matt Darois, RSCS, The Use of GIS, BIMs, and Digital Twins to Assist with Characterization and Decommissioning of Complex and Legacy Sites (bottom)

Technologies are available that are beneficial, cost effective, safe, and can reduce waste

Performance testing (in real world conditions) and documentation is necessary to advance innovation

Sharing of information and collaboration is important

Early communication with the regulator is important to ensuring the regulatory framework is in place to avoid delays in implementation of innovation Image Credit: WPTES workshop webpage source: Roulet and Daguin et. al (ONET Technologies, CEA, IRSN, VYSUS, EQUANS, TECNATOM--LD-SAFE Project), Laser technology for PWR/BWR RVI segmentation (top); and Bryan Bower, US DOE West Valley, Aggressive Deactivation of Product Purification Cell (PPC)-South of the West Valley Demonstration Project Main Plant Process Building.

Workshop participants expressed a strong interest in follow-up workshops and activities

WPTES intends to create an Expert Group on Innovative Technologies and Techniques to Support Characterization and Decommissioning of Complex and Legacy Sites

To better understand the state of art of technologies and techniques used in decommissioning Potential subgroups/subtopics include the following:

Identification of areas where innovation would be most beneficial Geospatial analyses to support subsurface survey design and data evaluation Guidance to support design and evaluation of continuously collected data (e.g., UAVs)

Best practices for data visualization and analysis using GIS and other software Characterization of concrete structures

To identify challenges to successful implementation of innovative techniques and technologies

To share lessons learned and good practices related to characterization of complex decommissioning and legacy sites

NEAs Working Party on the Technical, Environmental and Safety Aspects of Decommissioning and Legacy Management is looking for membership in its task and expert groups

WPTES hosted a workshop on innovative technologies to support characterization and decommissioning on November-December 2022

Workshop proceedings will be published later in 2023 with links to all of the presentations being made available

A follow-up workshop in 2024 is being considered Check out https://www.oecd-nea.org/jcms/pl_71664/innovative-techniques-and-technologies-to-support-characterisation-and-decommissioning-of-complex-and-legacy-sites
