We offer a wide variety of exclusive inspection capabilities for the global nuclear industry Engineering services

Rolls-Royce provides a comprehensive range of manually operated to fully automated inspection and non-destructive examination services for all phases of a nuclear reactor lifecycle.

With over 40 years of experience providing worldwide in-service support to civil nuclear plants, Rolls-Royce offers a comprehensive range of integrated surface inspection, non-destructive examination (NDE) and condition monitoring services.

Rolls-Royce provides:

  • Technique development
  • Inspection manipulator design and development
  • Safety justification
  • Production of inspection procedures
  • O site implement
  • Apprehensive analysis of result

Our inspection and NDE services can be implemented manually, remotely operated or fully automated and all solutions are tailored to meet specific customer requirements.

Rolls-Royce is a world leader in the development of innovative NDE and inspection techniques, and always strives to continuously develop both our manufacturing and in-service inspection techniques.  We remain at the forefront of the discipline by collaborating and investing with a number of industrial and academic partners:

  • Rolls-Royce is a long serving member and active participant in the steering group for the European network for Inspection Qualification (ENIQ)

  • We are a full industrial member of the UK Research Centre in Non-Destructive Evaluation (RCNDE), an EPSRC sponsored collaboration between industry and academia to coordinate research into NDE technologies.

  • Rolls-Royce is also working with Imperial College, the University of Strathclyde and the University of Bristol on the NDE aspects of the Nuclear Propulsion Critical Technologies (NPCT) project, to support next generation ultrasonic inspections.

Supporting Capabilities:

  • Visual inspection (including metallurgical methods)
  • Magnetic particle testing
  • Dye penetrant inspection
  • Phased array ultrasonic inspection
  • Ultrasonic inspection
  • Eddy current inspection
  • Digital radiography inspection
  • Surface defect inspection and metallurgical replication
  • Underwater replication
  • Electromagnetic interference monitoring
  • Irradiation damage analysis (#D atom probe)
  • Noise and vibration examination (including acoustic emission and resonance testing)
  • Alternating current field measurement
  • Alternating current potential drop
  • Composite inspection

Rolls- Royce have developed a range of replication techniques utilising compounds developed in conjunction with the supplier to solve many complex and difficult inspection requirements.

The replica’s ability to provide high definition surface replication together with bespoke application and surface preparation equipment allows high quality surface examination in remote locations. These replicas can then be inspected in a laboratory providing a high quality examination in a low dose environment. 

Replication offers:

  • The ability to inspect inaccessible surfaces indirectly by visual and microscopic techniques, including high magnification Scanning Electron Microscopy
  • The extraction of surface particles by the replica material also provides a means of analysing surface contaminants
  • The ability to take size measurements in very high dose areas
  • A permanent record of the site of interest, allowing defect monitoring over time by comparison with previous replicas
  • In air or underwater application
  • Elastic material properties allowing replication of cavities and other undercut geometries
  • The ability to obtain microstructural information from metallurgically prepared surfaces
  • Resolution of surface textures to <1μm. whilst maintaining exposure to ionising radiation to levels that are ALARP

Ultrasonic inspection

What is Ultrasonic Inspection?

Ultrasound relates to pressure waves that propagate at frequencies beyond the audible range of the human ear.  When an ultrasonic wave encounters a defect within the component the wave is reflected and scatters, changing the nature of the ultrasonic signal that is obtained by the receiver.

The signal recorded by the receiving transducer is known as an A-Scan, this signal represents the intensity of the ultrasonic energy that reaches the receiver in a fixed time window.  Rolls-Royce utilises the basic operational principle of ultrasound to inspect a wide range of different components. A number of bespoke, automated scanners have been developed to improve the accuracy, speed and reliability of the inspection. Data is automatically recorded and analysis is completed remotely to reduce the exposure.

Supporting capabilities:

  • Extensive experience of use of ultrasound in NDE
  • Automated ultrasonic techniques to improve accuracy, speed and reliability
  • Phased Arrays to reduce inspection time and cost
  • Conformable phased array to inspect components with irregular surfaces of personnel to ionising radiation
