Overview of application
Customer : BNFL
Supplier:Concol Systems Ltd.,UK.
Concol Systems Limited
were awarded a contract by BNFL to provide a replacement
data acquisition and display system at the United
Kingdom's first Nuclear Power Station, Calder Hall, at
Sellafield in Cumbria.
As part of BNFL's life
extension program and increasing monitoring
requirements for Calder Hall Power Station, it became
necessary to replace and update the existing data
gathering equipment and operator displays for four
reactors. The various updates of the system since its
creation in 1956 increased the quantity of
instrumentation and safety systems leaving a restricted
available space for the new equipment.
A compact data gathering
system was therefore required which would also allow for
future expansion over and above current requirements. To
this end two locations within each reactors control room
area were identified as data collection points with
duplicate top end computer gathering and logging data.
The equipment supply
included four Datascan networks. As great emphasis was
placed by BNFL on the reliability of the system,
redundancy was gained not only through software and
computer duality but was also built into the hardware
acquisition system, by employing multiple communication
links.
