During the annual calibration of the pressure sensors on the waste gas system a small amount of radioactive gases was released to the waste gas compressor room, and through the plant vent to the environment. The investigation showed that the impurities on the sealing surface of the instrumentaion isolation valve of the waste gas system were a probable cause of its leakage. The leak consisted only of noble gases: Kr-85m, Kr-87, Kr-88, Xe-133, Xe-135, Xe-135m. The release in excess of the alarm setting was in the duration of 5 minutes. The total calculated amount of the release was 1 Tbq Xe-133 equivalent, which represented approx. 0.9% of the annual regulatory release limit for noble gases. In the waste gas compressor room there was one worker at the time of the release. The estimated external dose from the release was 0.01 mSv. Whole body counting of the worker detected traces of Xe-133 and Xe-135 but the calculation showed negligible contribution to the annual dose.
An analysis by the Norwegian NGO Bellona of transborder trade operations with the customs code 840130 (irradiated fuel assemblies or fuel elements) show a more than twofold increase of import to EU countries of fresh nuclear fuel in cash terms – from 280 million Euros in 2022 to 686 million Euros in 2023. In physical […]
The French government has said it is "seriously" studying the option of building a plant to convert and enrich reprocessed uranium to cut its reliance on Russia following the invasion of Ukraine. The only plant in the world that currently converts reprocessed uranium for use in nuclear power plants is in Russia. "The option of […]
