Quality Management, Safety Management, and Safety Practices in Nuclear Power Plants

Our experts support companies in the area of nuclear engineering and the manufacturers and service providers supplying 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 local and international regulations such as Kerntechnische Ausschuss (KTA), American Society of Mechanical Engineers (ASME) or 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 the fulfillment 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 as 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

Nuclear Power Plant, Equipment, and Process Safety

Having performed safety analyses for many major international nuclear power projects in Germany and abroad our experts have several years of extensive process engineering knowledge and experience. Taking plant-specific requirements and conditions into account, they focus on the following elements when evaluating the safety of a nuclear power plant:

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

Nuclear Engineering Inspection Office

Safe operation of a nuclear power plant depends on the quality of the components and systems used in the facility. 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:

Radiation Protection

We offer comprehensive radiation protection services that support compliance with the requirements of Atomic Energy Regulations (Atomgesetz (AtG)), Radiation Protection Regulations (Strahlenschutzverordnung (StrlSchV)), X-ray Regulations (Röntgenverordnung (RöV)), and subordinate 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 the safe operation of a nuclear power plant, systems and components must be audited periodically and whenever modifications are made. Inspection can either be carried out by either doing functional testing or non-destructive testing. TÜV Rheinland evaluates pending plant modifications in relation to their effects on the safety of the overall nuclear power plant and how these changes will affect compliance with regulations of existing licenses. Our evaluations include:

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

Non-destructive Testing (NDT)

Our experts are specialists in the application of advanced non- destructive testing methods. In addition to our capabilities in conventional NDT and inspection services (VT, PT, MT, ET, RT, UT, LT), we can help you to master the special challenges of the nuclear industry with diverse solutions in advanced NDT methods encompassing:

Our NDT experts support nuclear energy projects through training, consulting and technical justification.

Shutdown and Decomissioning of Nuclear Power Plants

Our nuclear energy experts have acquired comprehensive knowledge over more than 20 years of expert evaluation in shutting down and decommissioning nuclear power plants of various designs and with other types of nuclear facilities. Our range of services includes:

  • Support for operators and service providers of nuclear plants in preparing licensing and planning documentation.
  • Expert evaluation and assessment of all nuclear decommissioning 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 decommissioning.

Legal Basis of Our Services

  • Atomic Energy Regulations (Atomgesetz (AtG))
  • Radiation Protection Regulations (Strahlenschutzverordnung (StrlSchV))
  • X-ray Regulations (Röntgenverordnung (RöV))
  • 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

We provide proper assessment for radiological safety for school

Do you need expert information about your radiological safety?

Parents are always concerned about the safety of children. Now one big concern is about radiological issues and many parents are already taking voluntary measurements.

A safety evaluation by an expert is important to a well founded sense of assurance. At TÜV Rheinland we have been offering impartial inspections for 140 years and we are now offering radioactive contamination analysis services in Japan.

Our services
Precise measurements of dose rates and surface contamination within the precincts of the facility and identification of any locations where radioactive substances are present in significant amounts.

Detailed analyses of samples taken from the precincts of the facility such as soil and water. Standard package includes gamma spectrometry analysis for two samples per facility.

Calculations of potential radiation exposure based on measurement data.

Recommendation of radiation protection measures as adequate.

How to apply
