INDUSTRIAL STANDARD SOLUTION Introduction The chiller is a CRITICAL part of the Thermosiphon installation. In terms of cost (approx. 1.5 MCHF) In terms of reliability and maintenance The chiller is a CRITICAL part of the Thermosiphon installation. In terms of cost (approx. 1.5 MCHF), is the most expensive part of the station. In terms of reliability and maintenance, contains the active parts of the circuit. As it is in the surface and its fluid is not radioactive it can be easily accessed for preventive and corrective maintenance. To solve this problem, an industrial standard solution will be used. To search for the more adequate supplier, a Market Survey is taking place. In this presentation, an overview of this Market Survey will be done.
