    <subfield code="a">&lt;p&gt;This paper gives an overview of the CORTEX project, which is a Research and Innovation&lt;br&gt;
Action funded by the European Union in the Euratom 2016-2017 work program, under the&lt;br&gt;
Horizon 2020 framework. CORTEX, which stands for CORe monitoring Techniques and&lt;br&gt;
EXperimental validation and demonstration, aims at developing an innovative core monitoring&lt;br&gt;
technique that allows detecting anomalies in nuclear reactors, such as excessive vibrations of&lt;br&gt;
core internals, flow blockage, coolant inlet perturbations, etc. The technique is based on&lt;br&gt;
primarily using the inherent fluctuations in neutron flux recorded by in-core and ex-core&lt;br&gt;
instrumentation (often referred to as neutron noise), from which the anomalies will be&lt;br&gt;
differentiated depending on their type, location and characteristics. In addition to be nonintrusive&lt;br&gt;
and not requiring any external perturbation of the system, the method allows the&lt;br&gt;
detection of operational problems at a very early stage. Proper actions could thus be taken by&lt;br&gt;
utilities before such problems have any adverse effect on plant safety and reliability. In order&lt;br&gt;
to develop a method that can reach a high Technology Readiness Level, the consortium, made&lt;br&gt;
of 20 partners, was strategically structured around the required core expertise from all the&lt;br&gt;
necessary actors of the nuclear industry, both within Europe and outside. The broad expertise&lt;br&gt;
of the consortium members ensures the successful development of new in-situ monitoring&lt;br&gt;
