Reactor 21 automatically tripped from full load on rate of change of Boiler Gas Outlet Temperature (BGOT) following a trip of the Main Boiler Feed Pump. The Emergency Boiler Feedpump was unavailable at the time of the trip due to maintenance. The Start-Up Boiler Feedpump was put into service manually when it did not automatically start, but it had to be shut down soon afterwards due to a priming oil pump problem which caused a small fire. The station fire team extinguished the fire using hand held extinguishers, but the Fire Brigade were called as a precaution.With no high pressure feed pumps available the boilers were part depressurised using the Boiler Emergency Depressurisation (BED) Valves and the reactor cooled with feed provided from the Shut-Down Boiler Feedpump. Approximately one hour after the auto-trip of Reactor 21, the average Gas Circulator Inlet Temperature for Boiler 22 (calculated by the Data Processing System) exceeded the Operating Rule Limit of 300 degrees Celsius by 2.3 degrees Celsius for approximately 30-40 seconds. This was a consequence of starting the Gas Circulator Low Speed Pony Motors whilst the boilers were being fed by the low capacity Shut-Down Boiler Feed Pump.

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.
Anke Herold, Executive Director Oeko-Institut, Freiburg (Germany), in Brussels about the claim to triple nuclear by 2050: IPCC scenarios vs forecast development of nuclear.
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 […]
