На NEWS опубликовали краткое сообщение с кратким описанием. Это фактически то. что финны передавали в МАГАТЭ.

The INES classification is the same INES 0. This is just update of the event description.

Situation at the Olkiluoto unit 2 was initiated 10-12-2020 10:22 UTC when hotter than normal water entered primary circuit water treatment system during maintenance work. The hot water caused breakdown of filter resin, which was carried in primary circuit through the reactor core into main steam pipes.

The resin material caused alarm of high radiation levels in the main steam pipes. This triggered reactor scram and main steam line isolation by plant protection automation. High radiation levels in the main steam pipes is criteria for Site Area Emergency due to it being possible indication of fuel damage.

The plant was taken to hot shutdown. Activity in the main steam pipes returned to normal after a short time. Primary circuit water chemical analysis confirmed that there are no fuel damage.
