4. Radiographic Testing 1. X-rays are produced by establishing a very high voltage between two electrodes, called the anode and cathode. 2. To prevent arcing, the anode and cathode are located inside a vacuum tube, which is protected by a metal housing. 3. The cathode contains a small filament much the same as in a light bulb. 4. Current is passed through the filament which heats it. The heat causes electrons to be stripped off. 5. The high voltage causes these “free” electrons to be pulled toward a target material (usually made of tungsten) located in the anode. 6. The electrons impact against the target. This impact causes an energy exchange which causes x-rays to be created.

6. Eddy Current 1)When the coil of wire wrapped around a piece of iron to generate the magnetic field that caused the eddy currents to form in the metal. In the field of NDT the coil is called the inspection probe. 2)The magnetic field that is generated by the eddy currents can be detected using this same probe. Eddy scope can be used to monitor the magnetic field being produced by these eddy currents. When there is a change in magnetic field from eddy currents, there is some sort of defect in the material that has been tested. Besides that it displays a change in the signal on the screen when the instrument sees a change in the magnetic field generated by it. 3)Eddy currents will be disturbed if there is some defects in material such as crack from their normal circular shapes. NDT technicians use many different types of eddy current testing equipment. Some are simple coils that are held on a piece of metal. Others use special probes that are pushed inside of tube such as those in heat exchanger units. 4)Radioactive water from the reactor is circulated through the tubes and cooling water that will be returned to a river or lake is circulated on the outside of the tubes. It is very important that the radioactive water and the cooling water do not mix. Therefore, technicians perform eddy current inspections on the tubes to find and defects that may be present before they become leaks in the tubing.

10. Magnetic Particle Inspection i. Pre-cleaning ii. Introduction of the Magnetic Field The required magnetic field can be introduced into a component in a number of different ways: a)Using a permanent magnet or an electromagnet that contacts the test piece b)Flowing an electrical current through the specimen c)Flowing an electrical current through a coil of wire around the part or through a central conductor running near the part. iii. Application of magnetic media MPI can be performed using either dry particles, or particles suspended in a liquid. With the dry method, the particles are lightly dusted on to the surface. With the wet method, the part is flooded with a solution carrying the particles. The dry method is more portable. The wet method is generally more sensitive since the liquid carrier gives the magnetic particles additional mobility.

11. iv. Interpretation of Indications After applying the magnetic field, indications that form must interpreted. This process requires that the inspector distinguish between relevant and non-relevant indications. The following series of images depict relevant indications produced from a variety of components inspected with the magnetic particle method. Demagnetization Parts inspected by the magnetic particle method may sometimes have an objectionable residual magnetic field that may interfere with subsequent manufacturing operations or service of the component. Possible reasons for demagnetization include: May interfere with welding and/or machining operations. Can affect gauges that are sensitive to magnetic fields if placed in close proximity. Abrasive particles may adhere to components surface and cause and increase in wear to engines components, gears, bearings etc. Demagnetization requires that the residual magnetic field is reversed and reduced by the inspector. This process will scramble the magnetic domains and reduce the strength of the residual field to an acceptable level.

14. Conclusion The visit to Malaysian Nuclear Agency have stimulate and reinforce a positive attitude towards the theory of non- destructive testing which have been learnt during lecture. We also exposed to non-destructive testing procedure and observe how the testing is carried out during the visit. As a result, these provide wonderful opportunities to extend our learning and to enrich our understanding about the equipment used in testing. Lastly, we found that there are many standard and regulations which have been adopted by the company to carry out the repair service.
