Nuclear Qualification Testing

The Nuclear Qualification Test Division of Stork East-West Technology offers both highly trained technical personnel and state-of-the-art facilities to the nuclear power industry. These facilities are constantly updated to keep abreast of the rapidly changing requirements of nuclear safety technology.

Approvals. Stork EWT test facilities fully meet the code requirements, standards, and guidelines of NRC and AMSE, as well as IEEE specification, such as IEEE-323, IEEE-344, IEEE-382, ASME QME-1-1994, and ANSI B16.41-1983.

Some of EWT's nuclear qualification capabilities and test parameters are as follows:

Seismic Qualification Testing.

30K force-pound simulator

  • Horizontal displacement: to 30" double amplitude
  • Dependent biaxial (2-axis) inputs:
  • Coherent random (multi-frequency)
  • Continuous sine
  • Sine beat
  • Time history
  • Modal testing

100K force-pound simulator

  • 13'x13' square table area
  • Independent biaxial (2-axis) inputs
  • Incoherent random (multi-frequency)
  • Continuous sine
  • Sine beat
  • Time history
  • Modal testing
  • Table response is recorded and analyzed in 1/12 octave segments from 1-200 Hz

Type Testing. Nuclear Qualification Testing involves the substantiation of an equipment's ability to operate under extended normal and adverse conditions by Type Testing. Type Testing combines the effects (on a single piece of equipment) of 40 years of normal operation (aging) with that of seismic disturbances and postulated accidents (Loss of Coolant Accident - LOCA).

Aging. Stork EWT has the capability of reproducing the life of equipment used in nuclear plants. This replication is accomplished by simulation. For example, acceleration of normal temperature and humidity conditions following the guidelines of IEEE specification. Additionally, extreme temperature, humidity, and radiation are imposed during operating life cycling.

Stork EWT life cycling, capacity for loading (electrically, mechanically, hydraulic, or pneumatic), is virtually unlimited and can be programmed to individual customer requirements.

Accident Simulation. The equipment and facilities at Stork EWT are frequently configured to simulate postulate accidents including that of a Pressurized Water Reactor (PWR), Boiling Water Reactor (BWR), and High Temperature Gas Cooled Reactor (HTGR). The simulation generally includes an equipment exposure to high intensity radiation, rapid changes to extreme temperatures, pressures, and/or chemical sprays. 

Valve Certification/Full Flow "Flow Interruption" Testing. Stork EWT experts generate test data to substantiate design parameters or operating criteria of valves, including (but not limited to) steam, water, and hydraulic flow capability, and all necessary electro-mechanical devices required to certify set pressures, pressure drop, response times, and flow characteristics.

  • Pressure/Flow Capabilities. The flow system is capable of operating at 3000 psig working pressure with a maximum sustained flow rate of 45 cubic feet per second of gas (approximately 330,000 SCFM) or high pressure water flow at the rate of 65,000 GPM, utilizing blowdown techniques.
  • Instrumentation. The system and instrumentation are computer controlled with the additional capability of magnetically recording all data with provisions for computerized analysis of the resultant test data at the test site. The following parameters can be recorded with our standard instrumentation:
    • Inlet gas pressure
    • Tank pressure (air and water)
    • Regulator set pressure
    • Air temperature
    • Flow (0-25,000 GPM) water
    • Water temperature
    • Valve stem displacement
    • Videotaping of operation and spray pattern
    • Delta pressure across test specimen
    • Replacement water volume
    • Replacement gas volume
    • Event sequence
  • Special System Features. Systems can be adapted to suit individual requirements.
