A strain gauge is mounted to the inside of a stainless steel housing Higher water level means more pressure on the housing, leading to elongation of the strain gauge The resulting change in electric resistance is translated into the water level information For calibration, a defined pressure is applied to the transducer

Example, not the actual product.

SFP Level Instrumentation Product 1: Pressure Transducer

Proven technology. Very simple. Adapted for NPP use.

SFP Level Instrumentation Product 1: Pressure Transducer

No in-pool mounting. Fully analog. Simple.

Not to scale.


SFP Level Instrumentation Advantages of Pressure Transducer

No mounting to pool liner Fully analog with no software involved Very simple, very low component count Can be used as a portable or fixed mounted device Very low power consumption No electronics or organic parts in SFP room No maintenance needed (calibration only) Calibration in situ by simply pulling up on the cable for some feet Completely diverse to the through-air radar solution, i.e. ideal combination: Different principle, different OEM, no software.

Press. Transducer + Thr.-Air Radar = SFP ‘Dream Team’!


SFP Level Instrumentation Product 2: Through-Air Radar

Live demonstration of Radar and Transducer will be available starting in June at AREVA’s SFP mockup in Lynchburg, VA!

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.


Product 2: Through-Air Radar

Temperature: ∼700º F (Waveguide tube/ stilling well). 160º F electronics/readout (located at end of ≤ 100’ waveguide tube outside of SFP room). Humidity: Saturated Steam Accident Radiation: N/A (only metal in SFP room) Accuracy: ± 0.3 in. Temperature Error: None Calibration: Not required, no drift With swivel flange in situ. Maintenance: None Waveguide bends: Several possible, flexible radiuses Software: SIL2 certified per IEC61508 Power consumption: Very low: 0.5W. Periodic wake-up feature and on demand measurem.

≤ 100ft waveguide, ¾ -2”

Nothing in the pool. Simple. Highly accurate. No organic parts in the SFP room. Proven.

SFP Level Instrumentation Advantages of the VEGA Radar Solution

No parts in the pool. Liner not touched, no in-pool mounting, independent from pool water forces. IEC 61508 SIL 2 (Safety Integrity Level) Design Certification, Seismic Cat 1 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 and temperature changes. Very flexible mounting (floor, wall, ceiling) Bent waveguide tube is not larger than any other connection with its protection. It can have several bends of different angles. Very rugged: explosion proof, all metal housing, waveguide tube can be thick walled for missile protection. Measurement forgives pipe dents. Extremely low power consumption, can be operated using two standard 9V batteries. 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. FCC Part 15 approved and tested Could also be configured for portable use. Most Reliable, 50+ Year MTBF Self Diagnosing (Smart Error Messages)


SFP Level Instrumentation AREVA Value Proposition

Through air radar is the only solution without parts in the pool. Can be mounted in diverse ways (floor, wall, ceiling). AREVA is the ideal hardware partner: We fully understand the post-Fukushima requirements, minimizing project risk. Exceptional customer support, started Nov. 2011 with three Round Tables and will continue in future with SFP Hardware User Group. AREVA provides augmented quality through seismic verification, quality oversight, water spray testing, software V&V, extended documentation.
