Impact

Various stakeholders contribute to the work carried out in TRANSAT and will benefit from the project outcomes. The production, storage, transport and other operations related to tritium will need a more specific framework in the long term. This project will bring major inputs to the existing technical and legal frameworks and to the development of appropriate rules, procedures, standards, legislation, etc. The outcomes will also bring new technical knowledge to the fission & fusion community and help the public and private stakeholders prepare for an appropriate global management and financial environment in the short, medium and long term horizon.

TRANSAT WILL HAVE TWO MAIN IMPACTS

TRANSAT will contribute to solving a number of key issues in the management of tritium in fission and fusion facilities, which will satisfy regulatory requirements and thus minimise environmental and possible resulting health effects.

The TRANSAT project aims at expanding the body of knowledge in the field of technical solution to mitigate the tritium release. New permeation barrier concepts and effluent detritiation treatments will be available at a TRL that generates trust in the technology and require limited development for industrial scale (TRL 5). Furthermore, improvement in tritium permeation and inventory modelling in fusion/fission facilities is also a key Outcome of the project that will help stakeholders to assess the tritium distribution in their process and thus identify where mitigation systems should be envisaged.

Stakeholders will then have new ways of investigation for tritium management and tritium mitigation strategies.

In the field of dismantling, a methodology is proposed to build a dismantling plan, which will be then applied on an installation with significant quantities of elementary tritium (10 TBq range). The expected impact is to validate a methodology for a safe dismantling of tritium handling facilities. Stakeholders as well as nuclear safety authorities will benefit of the results and recommendations. New international recommendations or rules may follow from the TRANSAT project results.

Tritiated waste management faces several issues, such as tritium mobility and uncertainty in the assessment of tritium inventory. The impact of the TRANSAT project will benefit nuclear waste producers, nuclear waste repositories and nuclear safety authorities.

By developing new confining drums concepts and innovative tritium inventory measurement or assessment methodologies, TRANSAT will improve the strategies for safe tritiated waste management at the European and international levels. The results, recommendations in the field of tritiated waste management will be disseminated and promoted, which could lead to new regulation policies.

TRANSAT will expand the knowledge on tritium and¬†further enhance regulatory oversight of tritium-related activities, especially in areas where tritiated particles are expected. TRANSAT project will contribute to increasing the accuracy of internal dosimetry for tritium and to improving the protection of human health from potential exposures to tritiated materials by preparing new standards and regulations. Communication in this field with stakeholders and more precisely with the International Commission on Radiological Protection (ICRP) and International Atomic Energy Agency (IAEA), is a key aspect of this project’s success.

TRANSAT will pave the way for robust science-based policy recommendations to decision makers in this area at EU
level.

Based on the new results obtained in the project, the advisory board comments as well as feedbacks from research abroad, a list of outcomes and recommendations will be provided to stakeholders, with whom close interactions are maintained during the project through regular meetings.

Considering the EC Nuclear Safety Directive from 2009 with its amendment from July 2014 introducing a high-level EU-wide nuclear safety objective and a set of rules to support the independence of national nuclear safety regulators, TRANSAT will establish close interactions with WENRA (Western European Nuclear Regulators’ Association) and ENSREG (European Nuclear Safety Regulators Group).

On this basis the project will contribute to the development of new European and international policy frameworks and rules for safe tritium handling.
