Abstract:
Le concept de « développement durable » se résume en trois « E » environnement, Energie et Economie. Il a apparu avec les problèmes de changement climatiques et l’épuisement des ressources énergétiques. Il faut trouver un équilibre entre prospérité économique, besoin énergétique et protection de l’environnement pour assurer un développement durable. L’énergie est le cerveau de l’économie mondial et permettant à des nombreuses populations de jouir de confort, de productivité et de mobilité des très hauts niveaux. De prime abord, nous avons tous besoins de l’énergie permanente, que ce soit pour cuisiner, pour éclairer, pour chauffer ou climatiser nos domiciles. L’énergie mondiale, provenant des ressources fossiles (charbon, pétrole et gaz naturel) utilisées à l’ère actuelle sont épuisables donc non renouvelable et leur utilisation sera plus coûteuse ; de plus elle est la première source d’émission des gaz à effet de serre (à savoir le 𝐶𝑂2, 𝐶𝐻4 … … ..) donc, Contribue au réchauffement climatique de la planète terrestre. Afin de résoudre ce problème d’émission, un bon nombre des personnes sont engagées dans la production d’électricité d’origine nucléaire, avec un problème de la gestion des tonnes de déchets radioactifs dégagées lors de son fonctionnement. Voilà pourquoi il est urgent de trouver des nouvelles sources énergétiques alternatives propres et inépuisables. C’est le cas des énergies issues du soleil, du vent, de l’eau, et des biomasses. Ces sources d’énergie renouvelable sont un moyen efficace de contribuer au développement durable d’un pays. A partir de ces énergies, il est possible de produire de la chaleur ou d’électricité en cogénération avec un minimum de pollution de l’environnement.

Abstract:
Abstract A rapid measurement method for aerosol particle size is required to clarify the formation mechanism of freshly-formed radioactive aerosols in accelerator rooms. A graded screen array (GSA) method only requires brief sampling. Therefore, the GSA method is suitable for the measurement of radioactive aerosols in the accelerator rooms. In this work, a conventional GSA was applied to measure the particle size distribution of an aerosol. An influence of the radioactive gas on the GSA measurement was found. The adsorption of radioactive gases resulted in a discrepancy between the results of the GSA method and those of the diffusion battery method. An improved GSA method was developed to measure the radioactive aerosol formed in the accelerator room. The adsorption was measured by the improved GSA, and the influence of the radioactive gas was eliminated. The result of the improved GSA showed fair agreement with that of the diffusion battery system.

Abstract:
Many countries are currently facing the issue of finding a proper solution to store radioactive wastes coming from nuclear energy production plants. The possibility to store them in underground tunnels is largely considered and investigated. In France, Andra (Agence Nationale pour la gestion des Déchets Radioactifs) selected the Callovo-Oxfordian rock clay (COx) situated in the Meuse/Haute Marne site (France) between 400 and 600 m depth as possible host rock deposit. The excavation of the storage tunnels is expected to create a fractured zone around galleries. However, the factures will be then gradually re-saturated by the underground water coming from the surrounding rock mass and the fractures are expected to self-seal in contact with water, thanks to the swelling potential of COx. The capacity of self-sealing of COx, i.e. closing of fractures after water contact and possibly restoring of hydraulic permeability, is thus of primary interest for the safety of the storage system with respect to water, gas and solutes transport. In the work presented in this paper, the self-sealing behaviour of the COx argillite was investigated through x-ray tomography. The tested samples show significantly different responses depending on the zone where they have been collected on site. The results of mineralogical analyses (x-ray diffraction) are used to understand the observed phenomena.

Abstract:
Radioactive materials for the medical, technological, and industrial sectors have been effectively regulated in the United States since as early as 1962. The steady increase in the exploration and production of shale gas in recent years has led to concerns about exposures to Naturally Occurring Radioactive Materials (NORM) and Technologically Enhanced Naturally Occurring Radioactive Materials (TENORM) in oil and gas waste streams. This study applied policy surveillance methods to conduct a cross-sectional fifty-state survey of law and regulations of NORM and TENORM waste from oil and gas operations. Results indicated that seventeen states drafted express regulations to reduce exposure to oil and gas NORM and TENORM waste. States with active oil and gas drilling that lack regulations controlling exposure to NORM and TENORM may leave the public and workers susceptible to adverse health effects from radiation. The study concludes with recommendations in regard to regulating oil and gas NORM and TENORM waste.

Abstract:
In Norway, the largest reported quantities of radioactive discharges and radioactive waste containing naturally occurring radioactive material (NORM) come from the oil and gas sector, and smaller quantities of other NORM waste are also produced by industrial or mining processes. The Gulen final repository for radioactive waste from the oil and gas industry from the Norwegian continental shelf was opened in 2008 and has a capacity of 6000 tonnes. As of 1 January 2011, a new regulation was enforced whereby radioactive waste and radioactive pollution was integrated in the Pollution Control Act from 1981. This means that radioactive waste and radioactive pollution are now regulated under the same legal framework as all other pollutants and hazardous wastes. The regulation establishes two sets of criteria defining radioactive waste: a lower value for when waste is considered to be radioactive waste, and a higher value, in most cases, for when this waste must be disposed of in a final waste repository. For example, waste containing ≥1 Bq/g of Ra-226 is defined as radioactive waste, while radioactive waste containing ≥10 Bq/g of Ra-226 must be disposed of in a final repository. Radioactive waste between 1 and 10 Bq/g can be handled and disposed of by waste companies who have a licence for handling hazardous waste according to the Pollution Control Act. Alternatively, they will need a separate licence for handling radioactive waste from the Norwegian Radiation Protection Authority. The goal of the new regulation is that all radioactive waste should be handled and stored in a safe manner, and discharges should be controlled through a licensing regime in order to avoid/not pose unnecessary risk to humans or the environment. This paper will elaborate on the new regulation of radioactive waste and the principles of NORM management in Norway in view of the International Commission on Radiological Protection's 2007 Recommendations.

Abstract:
This research establishes a decommissioning timeline for the existing oil and gas facilities across all of the Australian offshore oil and gas production basins. Minimal data exist in the public domain to estimate these decommissioning timelines and, more importantly, the significant waste volumes generated; including potentially hazardous wastes such as naturally occurring radioactive material (NORM). At this time there is no approved onshore radioactive waste disposal pathway in Australia to accommodate this material. Applying an estimation methodology, based on Norwegian decommissioning data with regional activity factors, allows a NORM waste forecast to be established for the decommissioning of Australian oil and gas offshore infrastructure. The total NORM disposal burden is estimated to be in the range of 223–1674 tonnes for decommissioning activity to 2060, with over 68% of this material generated between 2018 and 2025. Due to the sparsity of public domain data this forecast is deemed to be uncertain and excludes the NORM contamination anticipated to be present in subsea export pipelines, trunklines and well production tubing. Current regulations governing the categorisation and disposal of radioactive wastes across Australia are complex and regionally dependent. This regional variation makes the implementation of a national radioactive waste disposal facility more difficult, and encourages the export of radioactive wastes overseas for final disposal. Exporting of radioactive wastes potentially presents a higher risk compared with in-country disposal and is likely not an effective long-term proposition. A comprehensive NORM data collection and quantification assessment programme, spanning all onshore and offshore oil and gas infrastructure, needs to implemented to drive and verify a NORM waste management strategy for the wave of facility decommissioning projects that are fast approaching.
