In the very first stage of its existence PION was involved into the elaboration and application of industrial maintenance technologies mainly in corrosion protection, wear and erosion resistance coating, lubrication and cleaning technologies as well as radiation protection. Established in 2004 it had originally three MSC degree engineers graduated in mechanical engineering and specialised for nuclear industry, nuclear power plants in its staff. Nowadays, it was increased up to 14 engineers covering all important areas of expertise relevant for different industrial applications including and became the most important – nuclear power plants. Their work is supported by three administrative colleagues.

Nuclear industrial disciplines covered by PION’s expertise:

1. nuclear safety

   • deterministic safety analyses including hazard analyses specialized in deterministic fire risk analysis, seismic analysis
   • probabilistic safety analyses – Level 1 and Level 2 as well as risk informed applications, RiskWatcher
   • radiological consequences analyses
   • design for safety – physical separation, independence, redundancy, diversity, fail safe design, protection against single failure and common cause failure, protection against internal and external hazards
   • review and evaluation of Safety Analyses Reports and Safety Requirements Fulfillmet

2. mechanical engineering for Nuclear and Turbine Island as well as BOP
