CNEA has relied on Cementys’ fiber optic measurement technical expertise and know-how

Anticipating future energy challenges, Argentina asserts its will to increase its atomic energy industry. Argentina’s government has entrusted CNEA (Comisión Nacional de Energía Atómica) with the development of a new type of nuclear reactor, from low to medium electrical capacity, completely engineered and designed in Argentina.

The project, called CAREM 25, began in early 2014 at the Atucha nuclear site in the province of Buenos Aires.

CAREM 25 project

This new generation reactor, of reduced dimensions, will produce 25 MW which corresponds to the power supply of a 100 000 inhabitants city.

Cementys provides technical expertise to CNEA for the design and the implementation of a structural instrumentation and monitoring meeting the project’s requirements.

For this CAREM 25, Cementys favored to set-up a “long-term” instrumentation based on robust and viable Vibrating Wire sensors. These technology based sensors have been installed on French and worldwide nuclear power plants for more than 40 years and their reliability is no longer to be demonstrated.

carem-25-cnea_cementys_microvib

MicroVib® Sensors

In addition to so-called “traditional” sensors in the nuclear industry, CNEA has relied on Cementys’ fiber optic measurement technical expertise and know-how, to integrate optical fiber cable into several parts of the reactor’s slab and concrete walls.

“For such an ambitious project that is the CAREM 25, we desired to ensure a traditional structural monitoring (Vibrating Wire sensors), and improve it with an advanced technology that is optical fiber distributed measurement in order to better understand the behavior of the structure”, commented Vincent LAMOUR, technical director and civil engineering expert at Cementys.

Distributed measurement with optical fiber gives added-value data since temperature and strain perceived by the fiber optic cable is collected each meter over its entire length.

Slab’s instrumentation was installed during summer 2016, and allowed to verify the good behavior of the concrete during its pouring in October 2016. Optical fiber measurements emphasize the same temperatures and strains as recorded by the Vibrating Wire sensors, and moreover, provide many additional measuring data.

A dedicated web interface allows the CNEA Civil Engineering and Instrumentation engineers to visualize real time data from the various installed sensors.

Cementys’ engineering teams will continue to contribute to the coming phases of the project with their expertise, until the site’s commissioning in the first half of 2019.

Fiber Optical Gages,
a unique technology for specific applications

Fiber Optic Technology is suitable for severe applications
With over twenty years of existence in the industry, the technology of fiber optic strain gage based on Fiber Bragg Gratings (FBG) is now recognized. Operation is simple and the tools necessary for its operation are now available “off the shelf” (optical fusion/splicing “welding” machines, industrial connectors, interrogators). In addition, the number of Telecom specialized technicians knowing how to process optical gages is significantly growing. The advantages of the FBG gages are multiple, but the technology is still not sufficiently known. Continued efforts are needed to inform and train the industrial operators of FBG gages’ advantages:
– Total insensitivity to electromagnetic fields,
– Ease of use in hazardous areas (compliant with Class 1 Div 1),
– Long distance between sensor and measuring system (several miles)
– Possibility to install up to 20 FBG on the same single Telecom fiber,
– Long-term stability without any maintenance,
– High strain capability up to 10,000 microstrains,
– High fatigue strength up to 100 million of cycles
– Insensitive to moisture and corrosion
– Low cost due to High Volume Telecommunication Industry

All these criteria and benefits are promoting the use of FBG sensors (passive, without drift and without energy) in the medical, aerospace, railway, oil and gas, hydraulic and major infrastructure sectors.

The optical gage: the right solution

In many case studies based on Cementys’ experience, fiber optical gages expand the existing field of use of conventional resistive strain gages for:
– Measures in strong electromagnetic fields (railway, rotating machine, lightning hazard, particle accelerators)
– Class 1 Div1 measurements (LNG tanks, offshore platforms, turbo-generators)
– Passive measurements in humid environments (instrumentation for Topside and Subsea Infrastructures)
– Hydro-geological measurements
– Blood pressure measurements, etc.
Thanks to those advantages, fiber optical gages are now considered as an alternative or a complementary solution to the resistive strain gages. An upfront analysis of the environment and the scope of measurement is necessary to find the best technical and financial solutions between optical and resistive gages.
We must change old habits and rethink the use of strain gages considering the Fiber Bragg Grating solutions.

Pipeline leak detection

Optical fiber: a revolution for pipeline leak detection

Pipeline leak detection is so important… Even though pipelines are still the safest way to transport oil and gas products, spills and leaks may occur. These incidents can have an important environmental impact, incur cleaning costs, and deteriorate the company’s image.

Several technologies have been developed to monitor the pipelines to detect or prevent leaks (ultrasounds, flow monitoring, smart pigs…). Optical fiber recently brought a revolution to the sector: we can now have a distributed measurement all along the line using telecommunication fibers, giving us every foot the temperature, strain and vibrations of the pipe.

Most optical leak detection systems today use Distributed Temperature Sensor (DTS) monitoring. When the product is at a different temperature than the exterior environment, a passive monitoring system will be able to rapidly detect leaks by looking for hot or cold spots along the line. This type of measurement has an extremely low false alarm level, especially if there is a big difference of temperature (LNG, heated oil, pressured gas with Joule Thomson effect…).

But when the product is at the same temperature than the exterior environment, a passive DTS monitoring will not work. This is why Cementys developed an Active DTS monitoring system: in this case, we use a metallic cable to heat the line, in order to analyze both the temperature and the temperature variation. This real time analysis gives out the thermal capacity of the environment, directly linked to the presence of oil.

For long lines, Cementys developed the Transient Monitoring System. To use an active DTS system, one will need power to heat the line (around 1W per meter). We can see that this solution is hard to implement for lines longer than a mile. Our Transient Monitoring System analyzes the temperature variations due to daily and seasonal changes. After a learning period, the system is capable to detect a change in behavior therefore a leak.

Thanks to those technologies, Cementys can help you to monitor all of your lines.

Voids detection in Marine docks by Ground Penetrating Radar (GPR)

The GPR method uses radar propagation and reflection of electromagnetic waves of different frequencies.

A microwave antenna transmits pulses of very short duration in the soil or the structure, generally at frequencies ranging from 16MHz to 2.6 GHz (according to depth and resolution objectives). When the waves encounter a contact between two different dielectric permittivities environments, part of their energy is reflected, while the other goes deeper.

The acquisition system measures the travel time of the radar wave between its transmission and its reception. The depth is calculated using the travel time and the relative dielectric permittivity εr of the soil (v = c /√εr where c: speed of light and v: soil velocity).

However, this depth may be lower or even 0 if there is the presence of natural or artificial screens (clay soils, rebar mesh, metal plate, etc.).

During this GPR campaign, we used a 270MHz antenna that allows auscultation close to 6m deep.

Picture missing 

The above radargram highlights anomalies, between 32 and 48 abscises, linked to voids extended between 3.5m and beyond 5.6m deep. GPR measures detect also geometric targets regularly spaced that appear to be related to wooden beams.

New Asset Integrity Monitoring Opportunities for Future Energy Infrastructures
How long term trends affect Asset Integrity Monitoring strategies?
Energy infrastructures usually need long term investment. In a demographic trend feeding energy demand (1 billion world population growth by 2025), energy price volatility or geopolitical hands will not affect this strong long-term play.
As an Asset Integrity Monitoring Leader, Cementys should take into account the energy market future scenarii and seize associated opportunities !

Sustainability and Globalization
Recent Conference on Climate Change COP21/CMP11 in Paris illustrated how sustainability and globalisation will affect future energy investments. Keeping global warming below 2°C by 2100 and investing 100 billions USD per year in developing countries will promote “green” energy infrastructures, related to monitoring business opportunities :
  • Hydraulic Power in developing countries : Mandatory Structural Health Monitoring and Risk Mitigation
  • Windfarms Onshore and Offshore : Monitoring for Condition Based Maintenance
  • Gas transport facilities (LNG, pipeline, storage) : Asset Integrity Monitoring (commissioning, leak detection, intrusion)
  • Photovoltaic power stations : Monitoring for Condition Based Maintenance

Balanced Energy Mix 
Fossil fuel and Nuclear energies will play a major role in the progressive energy transition, specially in a growing energy demand perspective. Asset Integrity Monitoring will enable necessary CAPEX and OPEX reductions for new Oil&Gas and Nuclear energy infrastructures.
Service Life Extension and long term waste management (CO2 sequestration, radwaste geological storage) will also need robust asset integrity monitoring solutions.

Smart Energy Networks 
Smart grids and smart pipelines will be part of the globalized energy market, as failure costs are continuously increasing. Asset Integrity Monitoring has a marginal cost when it is decided before construction. As today’s Condition Based Maintenance of Rotating equipments needs accelerometers and thermometers to reduce by half operating costs, energy networks will use optical fibers to secure operation and optimize maintenance.

By developing innovative cost effective solutions and providing robust technologies worldwide, Cementys team will play its role in the challenging future of new and existing Energy Infrastructures!

Distributed strain monitoring of tunnels

Distributed strain monitoring of tunnels

Distributed strain monitoring of structures using optical fiber sensing is a brand new technique which has opened new possibilities in tunnel survey. Cementys was mandated to install its SensoluxTM® sensor for two different structures: the brand new extension of the Parisian metro line 12 and the 35 years old Fréjus tunnel, the longest road tunnel in Europe, between France and Italy. The cable-sensor was set up on sensitive areas during important operations: a fire-access during tunnelling for RATP and underneath a fresh air gallery before the excavation for the SFTRF. The optical sensor is based on Raman (respectively Brillouin) backscattering to measure temperature (respectively deformation).

 

The cable-sensor detects the deformation over its whole length, without any blind spot, with a spatial resolution of 0.5m, a precision of ±5µdef and a range of several dozens of kilometres.

The small diameter of the sensor (2mm) makes it easy to integrate in tunnels by gluing the optical cable in grooves carved on the concrete. The optical cable is thus protected for long-term monitoring, without any maintenance of the measure system and with no deviation of the sensor. Moreover, the installation presents a low level of intrusiveness due to the fact that the cable is integrated into the concrete.

Any circumferential deformation of the structure is transmitted to the cable rings, cohesive to the concrete, and detected by the interrogators.

The first measure is considered as the baseline and the following measures are compared with the first one to track relative motions. Consequently, the initial stress of the cable due to gluing does not impact the measures.

The sensor measures the deformation (compression or expansion) of the concrete to detect local damages as cracks or global motion such as convergence phenomenon. Data is retrieved from a long distance with the optical fiber for real-time monitoring of the tunnel thanks to optical technologies.
