The State of Texas reported that as a result of the failure of a fixed gauge on June 30, 2020, a worker likely received a dose exceeding 250 mSv (25 rem). The rotary element and the source tube came partially out of the gauge and while employees tried to put them back in, the source and the cover plate holding it came out of the source tube. Workers thought the 3.5 GBq (95 mCi) Cs-137 source was still in the gauge housing and picked up the pieces without knowing that one of the pieces was the source. One worker put the source into his shirt pocket. The licensee is conducting a re-enactment to collect information for dose reconstruction and calculation. The Radiation Emergency Assistance Center/Training Site (REAC/TS) has been contacted for biodosimetry. The preliminary estimate of the dose received exceeds the U.S. statutory limit for total effective dose equivalent. NRC EN54706
UPDATE: A total of seven individuals were exposed to the source. Three people held the source in their hands, and one of them also placed the source into his shirt pocket. Four individuals were near the source at distances ranging from 6 inches to 6 feet. Three of the exposed individuals were radiation workers and four individuals were members of the public. Event re-enactment and dose calculations were completed. Serial blood counts were conducted under the guidance and direction of REAC/TS. Whole-body doses to members of the public were ranged from less than 0.01 mSv to 0.05 mSv (0.001 rem to 0.005 rem). Whole-body doses to radiation workers were ranged from 0.08 mSv to 410 mSv (0.008 rem to 41 rem). The individual that received the highest dose was the radiation worker who placed the source into his shirt pocket which ranged from 380 mSv to 410 mSv (38 rem – 41 rem). This individual also received the highest dose to an extremity which was 310 mSv (31 rem) to the hand. No adverse clinical and physical biological effects were observed as a result of this event. The dose received by the radiation worker that placed the source into his pocket exceeds the U.S. statutory limit for whole body dose of 0.05 Sv (5 rem).
Last year, the Dutch Province of Limburg started an alliance in which, besides the local government, research institutes, small nuclear reactor (SMR) developers, utilities, industrial customers and funders cooperated. With this "Limburg SMR alliance" Limburg tried to lead the way towards an SMR in Limburg. The preferred site for a first SMR would be Chemelot, […]
From the IPFM: During a visit to the Civaux nuclear power plant on 18 March 2024, France's Minister of the Armed Forces unveiled a plan to use the plant to produce tritium for the French nuclear weapons program. Civaux is a civilian power plant that belongs to and is operated by Electricité de France. According […]
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 […]
Jan vd Putte quickly changed from dressing as the pied piper at the protest during the IAEA nuclear power conference to warn for the Russian nuclear power conglomerate Rosatom and its role in Ukraine.
