Case Study: Nuclear Power Plant Temelín, I&C Energo Czech Republic

I&C Energo was among the companies which significantly contributed to the construction of the nuclear power plant Temelín; it played a key role in its sphere of business in various supply chains. I&C Energo provides comprehensive services in the area of instrumentation and control systems, electrical systems and technological information systems for industrial customers. Between 2000 and 2002, Beamex's MC5 calibrators, particularly the first two units, were used to verify or calibrate over 3000 sensors and pressure and temperature measuring circuits, including other recalibrations.

During the onset of testing, other alternatives were proposed for the calibrator prescribed by the procedures – one French calibrator and the BEAMEX calibrator. Following ca. 2 months of testing, an internal evaluation was completed and, together with the customer, BEAMEX calibrators were selected for further use. In the first stage, two PC106's, including external probes for the launching stage of the NPP Temelín control system testing at the time, were purchased in 1998. In 1999, I&C Energo purchased the TC305 calibrator and at the same time, the company was learning about the MC5 calibrator at the International Engineering Fair in Brno. They tested the MC5 and subsequently ordered it. Based on an extremely favorable experience with the calibrator, several more of them were gradually purchased.

"We may conclude that MC5 calibrators passed a series of very demanding tests between 2000 and 2002", Jan Krška comments. In situ calibrations, both input and output tests were conducted at NPP Temelín in round-the-clock shifts. The MC5 calibrators, with their comfortable and simple controls, gradually overshadowed PC106 calibrators. Between 2000 and 2002, the MC5 calibrators, particularly the first two units, were used to verify or calibrate over 3000 sensors and pressure and temperature measuring circuits, including other recalibrations.
