“…La mesure de l'activité des isotopes 234 U et 238 U dans les eaux contribue à évaluer les conséquences des rejets, comme l'illustrent les 47 prélèvements et mesures d'eaux souterraines provenant de l'environnement des installations de traitement du minerai uranifère de Canon City (Colorado, USA) (Zielinski et al, 1997a). Ainsi, les échantillons prélevés à l'aval immédiat du site de traitement témoignent de la concentration en uranium la plus élevée (> 100 µg.…”

RÉSUMÉCette note synthétise les données récemment acquises par l'IRSN ainsi que les données disponibles dans la littérature, concernant l'utilisation des isotopes de l'uranium pour évaluer les conséquences dans l'environnement des rejets des installations du cycle du combustible nucléaire. Ainsi, les végétaux peuvent témoigner d'anomalies du rapport de masse 235 U/ 238 U par rapport à la signature de l'uranium naturel ( U activity ratio in aquatic environment, when secular equilibrium between isotopes occurs, is a tracer of the uranium releases from uranium milling or conversion.

“…Although the uranium released from U-mining exhibits the signature of natural uranium ( 235 U/ 238 U ¼ 0.72%), 234 U and 238 U have been successfully used to determine the distribution of uranium contamination in surface and underground waters. 1,2 Accidental releases involving nuclear fuels have been studied using isotopes measured in soils and plants after the criticality accident in Tokai-mura [3][4][5] or the Chernobyl explosion. 6,7 The consequences of the routine release from nuclear facilities (namely uranium-enrichment and nuclear fuel fabrication plants) have also been investigated in the air and in the surrounding plants with uranium isotopes.…”

Isotopic evidence of natural uranium and spent fuel uranium releases into the environment

Uranium and plutonium isotopes were measured in soils, sediments and waters in an area subject to the past and present discharges from the uranium conversion plant of Malvési (France). The isotopes (236)U and (239)Pu are well known activation products of uranium and they prove to be powerful tracers of spent fuel releases in soils and sediments. On the other hand (234)U and (238)U activities measured in waters can be used to distinguish between releases and background uranium sources. Such findings contribute to improve the monitoring of the actinides releases by nuclear fuel facilities (mining sites, conversion, enrichment and fuel plants, reprocessing plants).

“…This contamination was especially apparent in the Lincoln Park area—a subdivision a mile and a half north of the facility (Environmental Protection Agency 2008). Second, until 1979, both the uranium tailings that were a result of the ore processing and the tailings that were accepted at the plant from the Manhattan Project were stored in unlined ponds that allowed the toxic waste to seep into the surrounding soil and groundwater (Zielinski et al. 1997; Frankowski 2002).…”

Extant research on official frames centers on state campaigns, yet nonstate entities also utilize their own official frames. We extend the existing social movement literature by examining the unsuccessful framing efforts of a uranium mill in Cañon City, Colorado. Despite a history of environmental contamination and resultant health problems, the corporation deployed an official frame to reestablish the company's legitimacy and justify their actions following the controversy. Our data included newspaper coverage, archival documents, in‐depth interviews, and direct observation. Findings highlight critical factors that can undermine corporate official frames, and show that failed framing efforts can ultimately erode elite legitimacy.
