It will be the world's first long-term disposal facility for spent nuclear fuel. [a] [3] It is being constructed by Posiva, and is based on the KBS-3 method of nuclear waste burial developed in Sweden by Svensk Kärnbränslehantering AB (SKB). The facility will be operational by 2026, and decommissioned by 2100. [4] [5] [6]
Posiva Oy is a Finnish company with headquarters in the municipality of Eurajoki, Finland.It was founded in 1995 by Teollisuuden Voima (60% of stock) and Fortum (40% of stock), [1] two Finnish nuclear plant operators, for researching and creating a method of final disposal of spent nuclear fuel from their plants.
The Finnish Nuclear Energy Act was amended in 1994 so that all nuclear waste produced in Finland must be disposed of in Finland. [31] All spent fuel will be permanently buried in bedrock. The Onkalo spent nuclear fuel repository at Olkiluoto was selected in 2000 to become the world's first deep geological repository of spent nuclear

KBS-3 is also to be used in Finland at the Onkalo spent nuclear fuel repository, being built by Posiva. The disposal method consists of the following steps: [1] The waste is first stored in intermediate storage for 30 years. The waste is encapsulated in cast iron canisters. The cast iron canisters are encapsulated in copper (CuOFP alloy) capsules.
The Nuclear Waste Policy Act of 1982 established a timetable and procedure for constructing a permanent, underground repository for high-level radioactive waste by the mid-1990s, and provided for some temporary storage of waste, including spent fuel from 104 civilian nuclear reactors that produce about 19.4% of electricity there.

The film received overall positive reviews from Swedish film critics, with an average score of 3.6 of 5 according to Kritiker.se. [5] Praise was given for the suggestive presentation of the daunting task of communicating the dangers of nuclear waste far into the future, as well as the great dangers of handling the by-products of nuclear energy.

However, a Finnish law passed in 1994 prohibited the transport of nuclear waste abroad. [111] With this law, Finland became the first country that decided to encapsulate spent nuclear fuel into deep geological repositories. The construction of the first such repository, Onkalo, is set to begin in 2012, with an estimated completion date of 2020 ...
