On June 23, 2012, Rajasthan-5 was under planned biennial shutdown. Work was in progress to weld a piping connection for making alternate provision for water addition to the moderator system. During the work, tritium concentration in the work area increased when an opening was made in the moderator cover gas line. Two of the contract workers involved in the job got internal exposure of tritium equivalent to radiation dose of 24.32 mSv and 16.54 mSv. The radiation dose to the workers though less than the statutory annual dose limit of 30 mSv for workers, exceeded the dose constraints.
Rajasthan-5 is Pressurized Heavy Water Reactor (PHWR) based nuclear power plant. PHWRs use Heavy Water as coolant and moderator. Tritium activity in Heavy Water systems increases over a period of time. Tritium is a soft beta emitter and can cause internal exposure once it enters the body. Tritium gets removed from the body through natural processes.
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 […]
