Maximum Safety for the Highest Demands

Piping systems in nuclear facilities are subject to particularly high requirements for quality, documentation, and traceability.

As a manufacturer and supplier of pipe fittings, Nirotec is specifically geared to these requirements with its own nuclear department, a certified QM system according to ISO 19443, and proven experience in handling nuclear procurement projects.

Requirements in the Nuclear Industry

Components for nuclear technology applications – especially ITNS (Items Important to Nuclear Safety) – must be clearly documented and traceable throughout their entire lifecycle. The relevant regulations define clear requirements for materials, manufacturing, testing, and documentation:

KTA 1401 – General Requirements for Quality Assurance

KTA 3201 / KTA 3211 – Primary Circuit Components and Pressure-Retaining Parts

RCC-M – French Code for Nuclear Piping Components (EDF, Framatome)

ASME Section III (NB/NC/ND) – US Nuclear Code, Class 1/2/3

10 CFR 50 Appendix B – NRC Quality Requirements for Nuclear Facilities

ISO 19443 – Quality Management System for the Nuclear Supply Chain

What Nirotec Offers in Nuclear Technology

Nirotec has its own nuclear department that exclusively handles projects with increased QS requirements. We take care of the complete documentation and inspection planning – from order placement to delivery.

Our components are used, among others, in:

$

Safety-relevant piping systems (ITNS)

$

Auxiliary and ancillary systems of nuclear facilities

$

Retrofit projects and overhaul plans

$

Project-specific special applications

According to EN 10253-2

Our manufacturing includes Elbows and Tees according to EN 10253-2 Type B – a central requirement feature of safety-relevant nuclear technology systems. Type B components have increased minimum wall thicknesses at safety-critical points and are part of many ITNS projects where the highest demands on wall thickness, documentation, and traceability apply.

Typical Products & Solutions

All products available according to EN 10253, ASME B16.9 and project-specific drawings – in all common nominal sizes and wall thicknesses.

Materials

Depending on the regulations and application class, we supply in the following materials:

  • Austenitic stainless steels: 1.4301 · 1.4307 · 1.4404 · 1.4435 · 1.4571
  • Heat-resistant steels: P235GH · P265GH · P355GH · 16Mo3 · 13CrMo4-5 · 10CrMo9-10 · P91
  • Duplex & special alloys: 1.4462 · 1.4410 · 1.4501 · 1.4547 (6Mo)
  • Nickel alloys: Alloy 625 (2.4856) · Alloy 825 (2.4858) · Alloy C-276 (2.4819)

Material selection is project-specific, considering the respective regulations and plant classification.

Quality & Documentation

In nuclear technology, quality assurance and documentation are paramount.

Our manufacturing is carried out within the framework of a certified quality management system according to DIN EN ISO 9001.
Furthermore, we are currently preparing for auditing according to DIN EN ISO 19443 – the specific QM system for the nuclear supply chain, and AD 2000 for pressure equipment.

Our nuclear department ensures that all project-specific requirements for documentation and inspection planning are implemented.

Typical services in the area of quality and documentation:

  • Creation and implementation of project-specific ITPs (Inspection and Test Plans) with defined hold and witness points
  • Complete material traceability from raw material to component
  • Test certificates according to EN 10204 (3.1 / 3.2)
  • Non-destructive testing (UT, RT, PT, MT)
  • Positive Material Identification (PMI)
  • Hardness tests
  • External approvals by TÜV, customer inspectors, independent inspection bodies
