KSU

What KSU does

KSU (Kärnkraftsäkerhet och Utbildning AB) is the dedicated nuclear power training arm of Vattenfall, founded in 1970 and headquartered in Nyköping, Sweden. The company provides education, competence development, and simulator-based training for Swedish nuclear power plant personnel, with a portfolio of more than 50 courses spanning reactor physics, plant operations, maintenance, safety culture (Human Performance), waste management, and decommissioning. Its core technical assets include full-scale control-room replicas of Swedish BWR and PWR plants, a portfolio of graphical (GSIM), partial-scope (DSIM), academic (PSIM), and severe accident (HSIM) simulators, and the proprietary KSU Online (Blenda) learning platform hosted on security-classified premises.

KSU's business model is primarily a professional services and content-licensing model built around enterprise contracts with Vattenfall and Swedish nuclear operators (Forsmark, Oskarshamn/OKG, Ringhals, Barsebäck). Internal personnel enroll through plant HR procedures, while external customers request quotations via [email protected]; disclosed unit prices include 16,900 SEK for Lift Training Green, 15,900 SEK for Basic Reactor Physics, and 1,600 SEK per e-learning module. The company complements course delivery with consulting on simulation technology, course development, HTO investigation, and digital coaching, and sells digital products (e-learning, VR/3D/360 content, animations, illustrations, video) under one-time licenses.

KSU is expanding internationally via partnerships with GE Hitachi (global BWRX-300 SMR training), OSGE (Poland), Norsk Kjernekraft (Norway), and Blue Partner, while launching AI/automation proofs of concept with Vattenfall Fleet for decommissioning use cases. Its physical footprint spans the Technology and Training Centre (TTC) near Forsmark and additional training academies at Oskarshamn, Ringhals, and Simpevarp, with a new Nyköping headquarters inaugurated in 2023 and a new graphic simulator in Oskarshamn inaugurated in 2025.
