Applications arranged according to industry: aerospace, chemical-petroleum, electric power. With increased demand for higher resolution ultrasonic evaluation, computer-based systems or workstations now become essential.

In this paper a typical high resolution ultrasonic inspection system is presented. HIRUSIS, an mnemonic for HIgh Resolution UltraSonic Inspection System, is developed primarily for the purpose of high performance hidden flaw Cited by: 2. The purpose of ultrasonic inservice inspection (UT/ISI) of nuclear reactor piping and pressure vessels is the reliable detection and sizing of material defects.

Before defects can be sized, they must first be : E. Green. Qualification process for ultrasonic testing in nuclear inservice inspection applications. Washington, DC: Division of Engineering, Office of Nuclear Regulatory Research, U.S.

Reliable detection and sizing of material defects, which have been found in nuclear reactor piping and pressure vessels, has been shown [1,2] to be greatly affected by changing components of ultrasonic inservice inspection (UT/ISI) systems.

The work reported here, in conjunction with our previous work [3–5], focuses on: providing a more rigorous analysis of equipment Author: R. Hockey, E. Green, A. Diaz. Leveraging numerical simulations, optimize the design of an inspection system utilizing the data fusion of Ultrasonic and Radar modalities, and assess the defect detection capabilities for.

Ultrasonic Methods of Non-Destructive Testing covers the basic principles and practices of ultrasonic testing, starting with the basic theory of vibration and propagation, design and properties and probes, and then proceeding to the principles and practice of the various ultrasonic techniques for different types of components and structures, both metallic and non 5/5(2).

Thus it is clearly necessaryto continue developing techniques for inspecting austenitic welds. This Report reviews much of the work that has been reported on the ultrasonic inspection of austenitic welds.

Two examples are the evaluation of inservice inspection indications in austenitic steel piping and development of methods and criteria for safe continued operation of ferritic steel reactor vessels with low upper shelf fracture toughness. Other newer computer-based technologies that have impacted the process of design through finite element.

In recent years, the Pacific Northwest Laboratory has been developing the Synthetic Aperture Focusing Technique for Ultrasonic Testing (SAFT-UT) for the U.S. Nuclear Regulatory Commission (NRC). The program objective has been to develop and validate the SAFT-UT technology for inservice inspection of nuclear power plant by: In order to evaluate properties of inner defects at plant structures quantitatively, non-destructive inspection using ultrasonic testing (UT) has performed an important role for plant maintenances.

At nuclear power plants, there are many structures made of cast austenitic stainless steel (e.g. casings, valve gages, pipes and so on).Cited by: 1.
