Identification de radioéléments lors du démantèlement d'une centrale nucléaire grâce à une solution logiciel de mesure IA pour l'industrie

Use case: Nuclear dismantling


Optimization of Radioelement Characterization in
Nuclear Decommissioning
 

Context

Our customer is a company specializing in nuclear energy, faced with the complex challenges of dismantling nuclear sites. A major issue in this process is the potential presence of radioelements in the infrastructures. Ensuring the safety of personnel requires a precise assessment of the nature and activity of these radioelements.

​

Challenges

One of our customer's main challenges is to correctly identify radioelements and measure their activity from spectrometric data. However, these elements are often shielded by materials such as concrete, steel and aluminum, thus altering the spectra obtained compared with those from exposed sources. To accurately extract the true activity of shielded sources, it is imperative to know the exact nature and thickness of the shielding materials. What's more, too long a measurement time can have a negative impact on the efficiency of the process.

Requirements

The customer wanted a solution capable of characterizing the radioelements present in the materials and reconstructing their activity behind the screening, in order to anticipate the intervention process.

Solutions provided

SMARTIUM has developed an innovative solution based on an Artificial Intelligence (AI) algorithm trained by Monte-Carlo simulation. Based on a gamma spectrometry spectrum obtained by a GeHP detector or a NaI :

  • Precisely identify the radioelements present,
     

  • Determine their actual activity despite screening,
     

  • Identify the shielding material,
     

  • Estimate the equivalent thickness of the materials masking the sources.
    ​

Results 

The solution developed by SMARTIUM has demonstrated exceptional performance:

  • Accuracy

Reconstruction of activities with an uncertainty of less than 5%, even in the presence of significant screens.

  • Material identification

Reliable recognition of the type of screen material and estimation of its equivalent thickness.

  • Considerable time savings

Data acquisition in less than 10 minutes is enough to obtain usable results.

  • Enhanced performance

Accuracy 6 times greater than conventional measurement.
