Spent Fuel Pool Level Instrumentation

Through-Air Radar VEGAPULS

  • How It Works
    • A packet of microwave pulses are transmitted by the antenna system
    • This pulse is reflected by the water and received by the same antenna system
    • The running time of the RADAR pulse from emission to reception is proportional to the distance to the water surface.
    • "Distance to water surface“ is translated into the level information.
    • The radar pulse is not reflected (only insignificantly attenuated) by stream or dust particles or by uneven parts of the water surface.

    The first video shows the VEGAPULS 62 Extended Range version.

    The second video shows the many features of VEGA through-air radar, including effective operations despite decreased water levels, boiling water and saturated steam environments, high density smoke, and incidental debris.

Advantages

  • VEGAPULS 62 Extended Range is specifically designed to work well for agitated media under difficult conditions
  • Steam, dust and a moderate amount of foam will not be a concern for the measurement quality
  • Ignores debris with “Follow largest echo” setting. Debris usually causes weak echoes, as demonstrated in front of customers.
  • Condensation on antenna or waveguide pipe wall will be tolerated. Water accumulation can easily be avoided through drainage holes.
  • Very simple mounting due to self-centred flanges and all lightweight components.
  • No parts in the pool. Liner not touched, no in-pool mounting, independent from pool water forces
  • Tested per IEEE344-2004 and IEEE102323
  • IEC 61508 SIL 2 (Safety Integrity Level) Design Certification
  • No need for under water work for calibration or cleaning
  • No moving parts, very few parts in total (horn, pipe, electronics), very simple overall
  • No organic parts or electronics in the SFP room (horn and pipe are all stainless steel)
  • Independent from room pressure changes.
  • Bent waveguide tube is smaller than most other connection types (just 1inch outer diameter)
  • Very rugged: explosion proof, all metal housing, waveguide tube can be thick walled for missile protection.
  • Measurement forgives pipe dents.
  • Extremely low power consumption (<0.5W), backup uses AA cells.
  • No calibration needed; very simple if desired (swivel flange to turn horn for calibration)
  • Widely used, mature devices (300.000+ sold worldwide). Easy and long-term qualified service and spare parts availability.
  • Most Reliable, 50+ Year MTBF
  • Self-Diagnosing (Smart Error Messages)
