    AVB Gap Measurement

    AREVA steam generator inspection tool

    Understand the Condition of Your SG Support Structures with a New Approach to SG Tube Inspection

    The combination of steam and water flow causes Steam Generator (SG) tubes to vibrate. Anti-vibration bars (AVBs) are designed to limit the vibrating motion. Larger-than-designed distance between the AVBs and tube OD (or Gap) can lead to excessive vibration and unwanted wear at the AVB location, and potentially wear from tube-to-tube contact — ultimately causing tube leaks.

    That’s why AREVA recently developed two innovative NDE techniques for measuring both tube-to-tube and tube-to-anti-vibration bar gaps. The first technique uses a rotating ET probe that senses the proximity of adjacent AVB metal from changes in the electro-magnetic field. A second technique uses a UT transducer that can be rotated within the U-bend region to measure gaps based on ultrasonic pulse reflections received from the AVB. AREVA can now combine these two approaches to achieve accuracy better than +/- 1 millimeter. Plus, each measurement takes only minutes.

    Benefits:
    • Enhanced accuracy
    • Save time — only takes minutes per measurement
    • Reliable results through cross-correlation
    • Inspect early and avoid unnecessary downtime

    In-Service Inspection

    Reducing the hassles of reactor vessel examinations

    This new manipulator can support full 10-year, intermediate and follow-up surveillance inspections with minimal disruption of outage activity. Because of its technical innovation, plant operators no longer have to endure many of the hassles previously associated with in-service inspections. It’s the Trans-World System (TWS) remotely operated manipulator. It reduces vessel occupation time (VOT) and minimizes site resource requirements for ultrasonic examinations of reactor vessels.

    BWR Cutting-Edge Inspection Systems

    HawkEYE IVVI Inspection for BWRs

    Better BWR Inspection Coverage. Period.

    BWR in-vessel visual inspection (IVVI) requirements challenge utilities, especially in high flow conditions. Plus, as regulators review visual examination methods more closely, EPRI continues evaluating the adequacy of current inspection methods. That’s why AREVA offers the innovative HawkEYE remote mechanized visual inspection system for your BWRs. HawkEYE provides better images and access to more areas for inspection without increasing your outage schedule or personnel exposure. 

    Since its introduction, HawkEYE has obtained images of BWR equipment previously excluded from inspection. HawkEYE inspects jet pumps, feedwater piping, core-spray piping, and core-spray spargers directly above the fuel. In fact, HawkEYE has increased coverage for Jet Pump exams (DF-1, RS-2) from 30 percent to as much as 75 percent. 

    Check out the facts and celebrate. This is BWR inspection coverage you can count on:

    Benefits:

    • Quickly reaches hard-to-inspect areas
    • Produces video quality unmatched by manual methods
    • Works with or without a work platform
    • Is operated remotely to minimize dose
    • Enables parallel refuel and vessel maintenance activities

    Simple, Robust Telescoping Mast

    HawkEYE’s simple, robust telescoping mast delivers a remotely-controlled tool head equipped with a camera. The robust mast reduces flow-induced camera motion for improved image quality, and accesses the annulus area between the shroud and the vessel. It then rotates from the annulus to the core area, and accesses the area above the annulus to perform required inspections. 

    Operates on Proven Cart/Ring Technology for Convenience

    HawkEYE can also operate on the proven cart/ring technology used at various sites, performing shroud inspections that are “transparent” to the refuel floor schedule. Using this system, bridge support is needed only for installation and removal of the ring, cart, and HawkEYE manipulator. The manipulator’s design enables utilities to start inspecting the annulus prior to the shutdown cooling isolation window, providing margin for added work scopes or schedule slippage. 

    Field-Proven Underwater Technology

    HawkEYE’s underwater technology, field-proven in numerous applications, includes a sealed housing on all motors. This housing maneuvers both industry-proven color and radiation-tolerant black-and-white inspection cameras.

NDE for Engineers

NDE for Engineers

NDE for Engineers

(24 hours)

This course is designed for anyone who directly or indirectly is affected by NDE. No prior experience is needed in NDE or ASME Codes as the course dissects these Codes for the student.

Students will learn the basic principles of several NDE methods commonly used in the nuclear industry: liquid penetrant, magnetic particle, visual weld inspection, ASME III visual inspections, and ASME XI visual inspections. In addition, the principles of the eddy current, radiography, and ultrasonic examination techniques are covered. In the end, students will spend an afternoon actually performing some of these techniques.

The course provides an overview of why the nuclear industry does what it does in NDE terms. The material covers federal regulation, relevant ASME Section III subsections as well as ASME Section XI. This material is reviewed in detail with students to aid students in determining what NDE is required for various applications. The interrelation of these various codes is also explained in detail.

Practical exercises are used to provide students with the opportunity to consult the various codes and determine, on their own, what NDE methods are most appropriate for the application. Actual situations from AREVA’s business are used to illustrate practical applications in the student's daily work.

While the title states “for engineers,” this class is also beneficial for supervisors and managers of personnel. Past students have included engineers, vice presidents of organizations, foreign authorized nuclear inspectors, and personnel from subcontracted NDE companies.
