Nuclear - Energy

We believe that the safety of nuclear facilities is a major issue. To understand, evaluate, control and improve are indispensable actions to qualify your NDT process with confidence and at a reasonnable cost.

CIVA is used by most nuclear global players. Our deep knowledge of nuclear NDT cases, of qualification process, especially RSEM and ENIQ, and of constraints related to inspection in this area makes us an efficient partner.

The Scientific and Engineering Centre for Nuclear and Radiation Safety, establishment of the Federal Environmental Industrial and Nuclear Supervision Service (ROSTECHNADZOR) has delivered a Certification Passport for CIVA.

We contribute to your qualification dossiers

We know the cost of qualification dossiers. We know that a huge amount of energy is necessary in the nuclear field to builfd these dossiers. Thanks to simulation, you can reduce the number of necessary mock-ups, you can secure the design of these mock-ups and reduce the number of flaws to include.


We have written qualification dossiers or contributed to part of them. Thanks to simulation, you can vary the value of some parameters easily, and you can demonstrate the influence or the non influence of these parameters. ENIQ, RSEM, RCC-MRX, AMSE, we know the codes, rules and recommandations.


we secure your probe, mock-up or ndt process design

With CIVA, we can display the beam in the specimen.

We display the zone coverage, here with a phased array probe.

We design innovative probes.

Our methodology and our tools allow to optimize the size and the number of elements of your phased array probe.

We check the ability of your probe to detect the flaws you are looking for.

We check that the flaws that have to be inserted in your mock-up are well positionned in order to avoid complex and unwanted interaction (mode conversion...).

We can vary influential parameters in a range of values. These parameters can be related to the probe, the flaws, the mock-up or the inspection procedure.

Combined variations will allow you to reduce the number of mock-ups you will need, and to evaluate the range in which these parameters will have the most significant influence.

You can make all these simulations with CIVA. We can also propose our calculation capabilities to save time, with or without checking your configurations. We can use more that 25 calculation nodes, and we also have internal tools to extract results in a rigourous and efficient manner.

In 2013, we have made more than 50 000 calculations for our customers.

we help you understand complex results

Using simulation allows you to understand complex echos, coming from specific modes for example, in a weld.


Specific calculation may help you see what the result would be for cases with complex interaction between defects.


Unknown echoes, surprising amplitude, unexpected result, we help you understand physical phenomena thanks to simulation.

we can run and analyse complex and massive calculations

We can run simulations for you. Either complex cases with 3D CAD, anisotropic material, branched defects, tomographic cases... Or massive calculation cases with hundreds of flaws, parameters variations, multiple probes...


We have the computers to run calculations, we have the tools to manage thousands of results without mistake.
