Modeling of Ultrasonic Testing for Inspection of Nodular Cast Iron Insert
نویسنده
چکیده
Nodular cast iron insert will be used as the inner component of nuclear fuel disposal canister. The outer cover of the canister is copper tube of 50 mm nominal thickness. Nodular cast iron insert is cast around several steel channels, which also strengthen the structure. The mechanical properties of the cast iron insert will be tested according EN-1563 /1/. According the specifications 100% NDT should be carried out for the insert in order to detect possible defects. The standard EN-12680-3 /2/ describes ultrasonic testing of nodular cast iron components and it can be used when applicable. For practical application of ultrasonic inspection the cast iron insert has been divided to following zones.

NDT of Ductile Cast Iron from Nuclear Waste Storage Canisters
The concept for geological disposal of nuclear waste and spent nuclear fuel relies on a multi-barrier system with the copper/cast iron canister as the first barrier. The canister is designed to retain its integrity for at least 100000 years, which means that future glaciations need to be considered. A thick ice block together with hydrostatic pressure from groundwater would produce hydrostatic ...
متن کاملFailure Analysis of a Four Cylinder Diesel Engine Crankshaft Made From Nodular Cast Iron
The premature breakage in some four cylinder diesel engine crankshafts was reported. All crankshafts were failed from the same region. Failures had occurred in the first crankpin, the nearest crankpin to the flywheel. Dynamic analysis and finite element modelling were carried out to determine the state of stress in the crankshaft. FEM results revealed that the first crankpin fillet is the most ...
متن کاملUltrasonic Inspection of Sub-Surface Defects In Aluminium Die- Castings
Non-destructive testing using ultrasonic measurement is used to ensure the quality of the die-casting products. The quality of a casting depends on the presence of discontinuities such as porosity and on the final metallurgical structure. Discontinuities occurring in the sub-surface of the cast structure mostly have irregular surfaces which scatter the ultrasound waves and make ultrasonic testi...
