Abstract: A prototype of a new concept noise diagnostics data acquisition system has been developed recently to renew the aged present system. This new system is capable of collecting the whole available noise signal set simultaneously. Signal plugging and data acquisition are performed by autonomous systems (installed at each reactor unit) that are controlled through the standard plant network from a central computer installed at a suitable location. Experts can use this central unit to process and archive data series downloaded from the reactor units. This central unit also provides selected noise diagnostics information for other departments. The paper describes the hardware and software architecture of the new system in detail, emphasising the potential benefits of the new approach.

Keywords: reactor noise diagnostics; remotely controlled data acquisition; signal conditioning; signal validation; nuclear power plants; nucelar energy; nuclear reactors; signal plugging; process noise signals; Hungary.
