Nuclear Power Plants

Nuclear piping is defined by documentation and control as much as by dimensions. Every material, weld and test has to be traceable and reviewable.

Typical piping requirements


  • Compliance with national nuclear standards such as GOST R / TU 197 and PNAE G-7-010-89
  • Qualified procedures and welders
  • Complete traceability and multilingual documentation

Piping challenges


  • Strict qualification of manufacturer, procedures and personnel
  • Documentation volume and language requirements
  • Client and licensor witness points

How RFSS fits


RFSS holds approvals and authorizations from nuclear clients and regulators (see Quality), welds under nuclear-grade procedures, and keeps one traceable record from raw material to dispatch.
