Earlier this year, the Russian State Nuclear Inspection (GAN) reported increased incident statistics at the nuclear research installations. GAN ascribed the alarming data to the fact that a number of highly qualified workers left the research institutes after funding shortfalls had occurred. The statistics for the Russian nuclear power plants summarised for the period from January through November this year show the same tendency. The reasons are not specified, but an educated guess would explain the trend by a combination of social tensions in the Russian nuclear industry and ageing reactor installations.
More than 80 incidents this year
More than 80 incidents at Russian nuclear power plants were documented by GAN in January through November 1998. Similar statistics for the research reactors have not been made available so far, other than the unqualified GAN report mentioned above.
Russia operates 29 nuclear reactors, including 13 VVERs, 11 RBMKs, 4 LWGR-12s and one BN type. In 1997, only 61 among the 113 Russian research reactor installations were in operation.
Incidents involving nuclear fuel
In November this year, there were two incidents involving nuclear fuel at the Russian NPPs. At Leningrad NPP, loose grips were discovered on three fuel assemblies during refuelling of a reactor. The grips bind fuel elements together in a fuel assembly. The assemblies contained spent fuel and were highly radioactive. At Smolensk NPP, one of the fuel elements fell down while being relocated to a wet storage facility at the plant. The incidents did not lead to discharges of radiation into the environment, reports GAN.

Europe’s only multi-source, injection-ready CO₂ storage site will more than triple its capacity by 2028. The decision follows an agreement with Stockholm Exergi to transport and store up to 800 – 900 kilotonnes of CO₂ per year. “This decision is years in the making, and the culmination of decades of hard work from many, Bellona included” says Bellona Europa Director Jonas Helseth.
