On 13 February 1998, shutdown cooling of the reactor vessel was lost for several hours when suction isolation valves for the residual heat removal (RHR) system automatically closed. These valves closed due to the loss of the primary power supply to Division 2 of the Nuclear Safety Protection System, while the alternate power supply was unavailable because of maintenance. The unit had been shut down since 5 September 1996, and decay heat loads were relatively low. During the period the shutdown cooling system was unavailable, water in the reactor vessel began to heat up at a rate of approximately 0.6 deg. F per hour. The licensee declared an ALERT Emergency Classification at the discretion of the control room supervisor, who desired to bring additional personnel onsite to assist in restoring the RHR system. The RHR system was restarted approximately six hours after the initial event. Justification: This event is rated at level 0/below scale in accordance with Part III-3.1.1 of the INES User's Manual as a minor change in coolant temperature due to some degradation of cooling with a comparable large time available for corrective actions.
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 […]
