Abstract: The control system comprises an independent removable power module for each coil of a rod control mechanism equipped with three operating coils supplied from a three-phase current source. The power module is connected in series with the corresponding coil and comprises a rectifier circuit with three thyristors controlled in phase angle by a corresponding regulation circuit according to setpoint current values associated with the coil. A monitoring circuit connected to a display interface displays the current flowing in the coil associated with the power module. In the event of a fault, the module and coil involved are easily detected and replaced without requiring shutdown of the whole of the reactor.

Abstract: A data management system for obtaining data, relating to the maintenance and performance of an asset, processing the data and delivering it to an end user. A predetermined data set is collected and transmitted, and stored. The data are reconfigured into a predetermined format. An end user interface allows an end user to read the reconfigured data. Also provided is a computer apparatus for the management of data relating to the maintenance and performance of an asset, which generates a graphical user interface on a display screen. The graphical user interface consists of a data packet containing at least one data input section with at least one data field. Each section contains a text field which is capable of receiving, reading, and uniquely identifying hand written text.
