Rapid data acquisition from the safety system of the FRJ-2 reactor
Description
The central department for research reactors (ZFR) of the Juelich Nuclear Research Centre (KFA) is operating the reactors FRJ-1 (MERLIN) and FRJ-2 (DIDO) since 1962. In 1976, a Siemens 330 computer has been put into operation especially for the processing of data from the DIDO reactor, followed by another computer of the same type for the purpose of processing data from the ZFR department in general. The present report is a result of the work investigating 'Data acquisition and data processing in the FRJ-2' and primarily discusses the complex of 'fast analog and binary signals'. The activities in this field of work have been and still are mainly concerned with general problems encountered in adapting a currently 14-year-old reactor system to a digital computer, namely problems such as data decoupling in the safety system of the reactor, data acquisition using the CAMAC system, data transfer via an 'extended branch', data acquisition software as core-resident programs, temporary storage as common data, interpreting software as peripheral - storage - resident programs.

Die Zentralabteilung Forschungsreaktoren (ZFR) der Kernforschungsanlage Juelich (KFA) betreibt seit 1962 die Reaktoren FRJ-1 (MERLIN) und FRJ-2 (DIDO). Speziell fuer die Beduerfnisse des DIDO wurde 1976 ein Rechner SIEMENS 330 in Betrieb genommen, 1978 ein weiterer Rechner gleichen Typs fuer allgemeine Aufgaben der gesamten ZFR. Aus dem Anwendungsbereich 'Datenerfassung und -verarbeitung am FRJ-2' wird im vorliegenden Bericht vor allem der Komplex 'schnelle analoge und binaere Signale' vorgestellt. Schwerpunkte dieses Anwendungsbereiches waren bzw. sind noch: allgemeine Probleme der Adaptierung einer derzeit 14 Jahre alten Reaktoranlage an einen Digitalrechner; i.E.: Daten-Entkopplung im Sicherheits-System des Reaktors, -Erfassung mittels CAMAC, -Transfer ueber einen 'extended branch', Erfassungs-Software als hauptspeicherresidente Programme (HRP), Zwischen-Speicherung als Common Data (CD), Interpretations-Software als peripherspeicherresidente Programme (PRP).
