Seismic Vibration Testing IEEE 344 Services

Applied Technical Services, Inc. now offers in-house seismic vibration testing IEEE 344 services in full compliance with the requirements for equipment that is used in Nuclear Power Generating Stations. Such tests are required to demonstrate that the equipment can perform satisfactorily during and following a safe shutdown event upon an earthquake. Performance requirements for both SSE (safe shutdown earthquake) proceeded by a number of OBEs (operating basis earthquakes) are verified.

This standard guide is typically utilized either by equipment manufacturers to substantiate performance claims, or by users to verify performance of components or systems  as part of a qualification program.

Specifications/Features:
  • Fully Compliant with IEEE 344, GR-63-CORE, AC-156, IBC
  • 3 Independent Simultaneous Axes of Motion (X,Y,Z translation)
  • Table Size of 36"x36" with Grid of 1/2" - 13 Tapped Holes on 4"x4" Pattern
  • Actuators Rated at 10,000 lbf
  • Peak Displacement of 12 Inches P-P (+/-6")
  • Rated Velocity of 52 IPS
  • Frequency Range of Operation 0-100 Hz with Ability to Operate Up to 150 Hz for Purposes of Resonance Searches
  • State of the Art PC-Based Digital Controller (Vibration Research) and 12 Channels of Piezoelectric Accelerometers
  • Independent High-Speed DAQ Systems for Chatter Monitoring (64 Channels)
Quality Standards:
  • ANSI/ASME NQA-1 Nuclear Quality Assurance Requirements
  • 10CFR50 Appendix B Nuclear Quality Assurance Requirements
  • 10CFR21 Requirements for the Reporting of Non Conformances
  • ISO/IEC 17025 Competence of Testing and Calibration Laboratories
  • ISO 9001 Quality Management System
