What Svensk Kärnbränslehantering does

Svensk Kärnbränslehantering AB (SKB) is the Swedish state-mandated company responsible for managing all radioactive waste from the country's nuclear power plants. Founded in the 1980s and headquartered in Solna, Sweden, SKB operates as a regulated monopoly under Swedish law, financed by statutory fees levied on the nuclear power industry. The company runs an integrated waste management system comprising the Clab interim storage facility for spent nuclear fuel in Oskarshamn, the SFR final repository for short-lived radioactive waste in Forsmark, and a specialized maritime and road transport system centered on the purpose-built vessel m/s Sigrid. SKB is also developing the Kärnbränsleförvaret, a deep geological repository for spent nuclear fuel at Forsmark based on the proprietary KBS-3 method using copper canisters, bentonite clay buffers, and stable crystalline bedrock, supported by an encapsulation plant (Inkapslingsanläggningen) currently under development.

SKB's technology base rests on 40+ years of dedicated R&D, anchored by two purpose-built research facilities: the Äspölaboratoriet, a 460-meter-deep underground laboratory on Äspö island used for geological and barrier studies, and the Kapsellaboratoriet, a canister encapsulation development laboratory in Oskarshamn. The company maintains a scientific publication database of more than 5,338 reports, reflecting the long-horizon empirical and theoretical work underpinning the multi-barrier safety case. Two wholly-owned subsidiaries extend the business: SKB International AB, which exports SKB's accumulated knowledge to international counterparties (with active engagements including bilateral cooperation with Finland's Posiva and Korea's KORAD in 2026), and SKB Näringslivsutveckling AB, supporting business development. The core business model is fee-for-service waste management under statutory obligation, with no commercial pricing or competitive sales motion. Customer concentration is structurally total within the Swedish nuclear industry, but revenue is contractually guaranteed by the funding model.

Core offering

SKB operates the full Swedish nuclear waste management chain: interim storage of spent nuclear fuel at the Clab facility in Oskarshamn, final disposal of short-lived radioactive waste at the SFR facility in Forsmark, dedicated maritime and land transport (m/s Sigrid and transport casks), and the development of a deep geological repository for spent fuel (Kärnbränsleförvaret) coupled with a copper-canister encapsulation plant. The service is delivered under a state mandate, financed by fees from Swedish nuclear power operators, and built on 40+ years of proprietary R&D.

Product overview

SKB operates a comprehensive nuclear waste management system with three interconnected facilities: Clab (interim storage for spent nuclear fuel), SFR (final repository for short-lived radioactive waste), and the future Spent Fuel Repository. The system includes specialized transport via m/s Sigrid, encapsulation technology for copper canisters, and extensive research through Äspölaboratoriet and Kapsellaboratoriet. SKB International commercializes their 40+ years of accumulated expertise globally.
