Our Auditing and Consulting Services

Quality Management, Safety Management, and Safety Practices

TÜV Rheinland supports companies in the area of nuclear engineering and the manufacturers and service providers that supply the nuclear engineering market. We assess management systems and applicable processes and provide support to licensing and regulatory authorities. Our services include:

  • Assessment and qualification of manufacturing based on international and German conventional and nuclear regulations such as Kerntechnische Ausschuss (KTA), American Society of Mechanical Engineers (ASME) and French RCC-M
  • System and process audits
  • Conformity certifications
  • Safety management and safety practice inspections and consultations
  • Documentation reviews

Conformity Evaluations of Systems and Nuclear Components

Conformity analyses review basic data and design data relevant to fulfilment of requirements in applicable nuclear and conventional engineering regulations and specifications. Our support can be provided in the context of a formal preliminary review or through consulting services rendered as part of the layout process. The conformity analysis is carried out for components and systems primarily in the following fields:

  • Equipment for handling machinery and materials
  • Electrical and control system engineering
  • Pressure vessels in nuclear engineering

Plant, Equipment, and Process Safety

Our experts have several years’ worth of extensive process engineering knowledge and experience through their safety analyses for numerous major projects in Germany and abroad. Taking plant-specific requirements and conditions into account, they focus on the following elements when evaluating the safety of a nuclear plant:

  • Safety concept and safety classification
  • Reactor design and thermodynamics
  • Third Party Inspections
  • Functional analyses
  • Incident analyses
  • Fire prevention
  • Service life analyses

Radiation Protection

TÜV Rheinland offers comprehensive radiation protection services that support compliance with the requirements of atomic energy regulations, radiation protection regulations, X-ray regulations and related regulations. These services focus on the following aspects:

  • Location and environment
  • Dispersion simulations and emergency management
  • Testing of X-ray equipment
  • Radiation protection planning and testing of accelerators
  • Radiation protection planning and testing of radionuclide laboratories
  • Testing of tightness of radioactive sources
  • Disposal
  • Release procedures and clearance measurements
  • Gamma spectrometric in-situ measurements and laboratory measurements
  • Radiation protection measurements
  • Shielding calculations and radiology-related occupational safety and health issues

Condition Monitoring

For safe operation of a plant, systems and components must be audited periodically and whenever modifications are made. This can either be carried out by doing functional testing or non-destructive testing. TÜV Rheinland evaluates pending modifications to a plant in relation to their effects on the safety of the overall plant, and how they will affect compliance with regulations from existing licenses. Our evaluations include:

  • Periodic functional testing
  • Non-destruction testing
  • Expert evaluation of modifications
  • Operational radiation protection
  • Discharge and release
  • Dose determination

Shutdown and Removal of Nuclear Plants

TÜV Rheinland has acquired comprehensive experience and knowledge through more than 20 years of expert evaluation in shutting down and removing nuclear power plants of various designs, along with other types of nuclear facilities. Our range of services includes support for operators and service providers in preparing licensing and planning documentation and expert evaluation for licensing and regulatory authorities in all phases of shutdown and removal. These services include:

  • Support for operators and service providers in preparing licensing and planning documentation
  • Expert evaluation and assessment of all removal strategies related to radiation protection measures
  • Assessment of dismantling procedures and handling facilities, waste management, release procedures, disposal, transport, and storage of radioactive materials
  • Expert evaluation of waste storage facilities
  • Expert evaluations for licensing and regulatory authorities in all phases of shutdown and removal

Nuclear Engineering Inspection Office

Safe operation of a plant depends greatly on the quality of the components and systems used in the plant. To ensure quality, our inspectors are continuously deployed to suppliers of these components and systems, but our activities are not limited to inspection. We also support you in the following areas:

  • Quality inspection of the components and systems used in a plant
  • Expediting
  • Construction supervision and works acceptance
  • Non-destructive testing

Legal Basis and Standards for Our Services

  • Atomic energy regulations
  • Radiation protection regulations
  • X-ray regulations
  • Standards of the Nuclear Engineering Committee (Kerntechnischer Ausschuss, KTA)
  • ASME – collection of standards from the American Society of Mechanical Engineers
  • RCC-M – AFCEN Design and Conception Rules for Mechanical Components of PWR Nuclear Islands
