Stress corrosion cracking (SCC) in light water reactors (LWRs) has been a persistent form of degradation in the nuclear industry. Examples of SCC can be found for a range of materials in boiling and pressurized water reactor environments, including carbon steels, stainless steels, and nickel-base alloys. The evolution of SCC is often characterized by a long initiation stage followed by a phase ...

This paper evaluates the added resistance of a torpedo shape AUV, moving inside a water pipeline, due to wall effects within the tube. Today, there are long length pipelines of water or petroleum that need to regular inspection. Early detection of failure will help to prevent breakdown and avoid the huge cost of an accident. As pipelines are enclosed environments and difficult to access, pipeli...

Fagan inspections are a structured review of development documents that consists of individual preparation, a meeting and rework by the author of the document. The meeting is used to log the defects found in preparation and to search for more defects. The effectiveness and eficiency of the meeting is typically low as compared to that of the preparation. This paper describes the use of an EMS to...

The article presents a search for links between the Periodic Technical Inspections of Vehicles (TI) and traffic accidents due to vehicle technical defects in Slovak Republic. Based on these links, it is sought assess justification TI regarding road safety. For this purpose, statistical data accidents, caused by as well concerning carried out were examined. first finding was that approaching end...

Hidden corrosion remains a significant problem during aircraft service, primarily because of difficulties in its detection and assessment. The non-destructive D-Sight testing technique is characterized by high sensitivity to this type damage an effective sensing tool for qualitative assessments hidden structures used numerous ground service entities. In paper, the authors demonstrated new appro...

PT. BEST is a manufacturing industry that engaged in processing palm cooking oil, one of the processed products from production process shortening which margarine for household products. In found very high level product defects, several factors become obstacles cause defects. The defects resulted low quality and decrease amount production. Product improvement using DMAIC Six Sigma concept appro...

The article presents the possibility of verifying efficiency a diesel particulate filter (DPF) with use particle counters using two different measurement methods. tests were carried out at vehicle inspection station condensation counter (CPC) and diffusion charger (DC). This results measurements 50 vehicles. Removal from is prohibited but known phenomenon throughout EU. task periodic technical ...
