A lead radiographer approached the end of the guide tube having assumed that the source had already been retracted into the shielded camera. After approximately 90 seconds the assistant radiographer entered the area. The assistant radiographer’s alarming rate meter and survey meter indicated the presence of radiation and the two individuals left the area. The lead radiographer was wearing a whole body dosimetry badge which was sent for emergency processing. The dosimeter was measured by the vendor at 8.36 mSv (836 mrem). Based on re-enactments during the State of Ohio’s reactive inspection, the licensee estimated the lead radiographer’s whole body dose to be 130 mSv (13 rem), which exceeds the statutory limit of 50 mSv (5 rem) to the whole body. The licensee also estimated the lead radiographer’s extremity dose to the hand to be 65 mSv (6.5 rem), which does not exceed the statutory limit of 500 mSv (50 rem) to an extremity. The licensee is assigning the calculated whole body and extremity doses to the individual because the lead radiographer was wearing the dosimetry badge on his belt; therefore, the badge was not optimally positioned to record his dose from the source. The State of Ohio made the following observations during their reactive inspection: the lead radiographer’s alarming rate meter had a dead battery; the radiographers did not utilize a source collimator causing the source to be unshielded; the lead radiographer’s survey meter was not fully functional; and the lead radiographer had not tested his survey meter for proper response on the day of the event.

Yesterday, the ANVS, the Dutch nuclear supervisor, authorized the transport of up to six shipments of fissile enriched uranium from Russia to Urenco in Almelo. This is remarkable because after the Russian invasion, almost two years ago, the uranium-enriching state-owned company in Almelo claimed to be "very concerned" about developments in Ukraine and therefore "stopped […]
[The Guardian]: "As nuclear plant is hit by further delay, real cost will be far higher after inflation is included, as project uses 2015 prices. The owner of Hinkley Point C has blamed inflation, Covid and Brexit as it announced the nuclear power plant project could be delayed by a further four years, and cost […]
From WNN: In 2022, 13 EU countries with nuclear electricity production generated 609,255 GWh of nuclear electricity - down 16.7% compared with 2021, according to figures released by Eurostat, the statistical office of the European Union. It noted this is the lowest level registered in the period from 1990, the first year for which comparable […]
In the IEA-report on renewables published yesterday, the following is notable: Over the coming five years, several renewable energy milestones are expected to be achieved: In 2024, wind and solar PV together generate more electricity than hydropower. In 2025, renewables surpass coal to become the largest source of electricitygeneration. Wind and solar PV each surpass […]
EPZ, the operator of the Borssele nuclear power plant, has long claimed that it recycles "95 percent" of its nuclear fuel, and that only "5 percent" remains as nuclear waste. Following a complaint by Laka, the Board of Appeals of the Dutch Advertising Authority, ruled yesterday that these are misleading environmental advertisement claims. In its […]
