SFP Level Measurement How Through-Air Radar Works 1/2

The Only Solution With Nothing in the Pool.

Operating Principle 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.

SFP Level Measurement How Through-Air Radar Works 2/2

Waveguide Pipe Electromagnetic waves travel through space, e.g. radio. They also travel inside a hollow pipe of any shape. Correctly dimensioned, the pipe makes a very low-loss transmission line, better than a coaxial cable. In SFP applications, the waveguide pipe transports the measurement signal to a mild environment where the electronics can be placed. The waveguide is 100% stainless steel. It is very rugged and insensitive to high radiation and temperature.

Radiation and Temperature Protection with No Reason for RAIs.

Through Air Radar Ignores Debris

Objects floating on the water will not impact the correct reading. Objects submerged below the water will not be seen. With uncovered debris (or built-in structures), the return signal will normally be greater for the water level and the actual water level will be detected. Concrete debris will not affect the reading as concrete isn’t a good reflector. Physical separation of the second device prevents concurrent loss of both readings.

Except in extreme cases, debris is not an issue.

Spent Fuel Pool Level Instrumentation by AREVA: Safe, Simple, Reliable, Economical. p.10

► Through-Air Radar follows largest return signal

► Most reflections from debris won’t reach the horn antenna (not perpendicular to radar beam)

► Through-air radar will continue to track water level and ignore fallen objects in beam

Advantage of Through-Air Radar Surface Tracking Capability

Can ignore debris while providing accurate spent fuel pool level measurement.

SFP Product Demonstration in Lynchburg

The debris, steam and moving water capability of the AREVA/VEGA Through-Air Radar system were demonstrated in front of customers.

Written customer summary: “In conclusion, the demonstrations offered compelling evidence that the Through-Air Radar measurement technology is a viable candidate.”

The 25ft ‘Moving Wall’ allows the simulation of quickly rising and falling water level. Large debris is introduced in the beam area at different heights - with no effect.

Installation including a long waveguide with 180⁰ and 90⁰ bends is raised and lowered above pool.

The attendees see the display at all times.

Buyer decision

Short Lead Times Reduce Project Costs.

Spent Fuel Pool Level Instrumentation by AREVA: Safe, Simple, Reliable, Economical. p.15

Purchasing Cost Low due to low component count and off-the-shelf components. Low project cost due to short delivery lead time and therewith shorter

overall project duration.

Installation Cost Low due to no work in the pool and all standard (pipe and cable

installation) work. No heavy components, no lifting equipment needed.

Start-up Cost Low due to simple system handling and pre-set parameters.

Operation and Maintenance Cost Low due to maintenance free technology. Battery replacement and verification of correct function only.

Through-Air Radar Low Total Cost of Ownership

Summary A Second Opinion on Through-Air Radar

“ Pulse Burst Radar accurately and reliably measures a wide range of media in a broad range of process conditions, from calm product surfaces and water-based media to turbulent surfaces … . As a non-contact device, Pulse Burst Radar is not susceptible to the complications that arise whenever a probe contacts the process media, such as coating … or corrosive attack due to aggressive chemicals. The greater the measuring range, the more does radar prove itself to be the economical solution, given the cost of extended probe lengths. Radar is virtually unaffected by temperatures, pressures, the presence of vapors, … As a 100% electronic instrument, the absence of moving parts translates into low maintenance costs. As a two-wire, loop-powered device, power requirements and installation are vastly simplified.” (Source: Other US NPP Instrumentation Vendor’s Website)

In-situ calibration Normal operation In-situ calibration method: Horn antenna is rotated

to calibration position simply by loosening the lap joint flange screws.

Flange away from pool minimizes risk of dropping parts in pool.

A hand-held target can be walked along the poolside at known distances to check sensor calibration.
