What UJP PRAHA does

UJP PRAHA a.s. is a privately held Czech joint-stock company headquartered in Prague-Zbraslav that operates across three interlocking business lines: medical radiotherapy devices, certified radioactive material transport containers, and specialty nuclear materials. The company historically continues the activities of the former Institute of Nuclear Fuels (Ústav jaderných paliv) and traces uranium processing research back to 1972, though the current entity was incorporated in 1996.

The medical device portfolio centers on the TERABALT cobalt-60 megavoltage radiotherapy irradiator and an integrated software stack comprising the TERASIX X-ray simulator, PlanW treatment planning system (supporting IMRT/IMAT with DICOM 3), TERAGIS record-and-verify system, and PLANVERI independent Monte Carlo dose calculation verification. The nuclear industry segment offers IAEA SSR-6 (2018) certified Type A, Type B(U), and neutron source packaging sets — over 100 certificate types — and is the only facility in the Czech Republic offering transport containers utilizing metallic uranium shielding. Advanced materials include tungsten heavy alloys (90-96 wt% W), zirconium alloys backed by a ~50,000-data-point corrosion database, nickel superalloys, beta-titanium alloys for implants, and uranium compounds.

The business model is enterprise B2B with direct field sales to hospitals, nuclear operators, defense customers, and industrial clients, supplemented by SÚJB-approved radiation protection training courses and a dormant electricity distribution license. GTM motion relies on regulatory expertise, IAEA/SÚJB certifications, and 50+ years of uranium handling know-how rather than volume marketing. Recent strategic activity is concentrated in R&D partnerships with ČVUT FJFI, ON Semiconductor Czech Republic, and IAEA, plus a CZK 349M National Recovery Plan grant for radiation-resistant microelectronics and multiple new packaging set launches in 2026.
