Development of DCC Software Dynamic Test Facility

Abstract

This paper describes a test facility for future dynamic testing of DCC sofrwore used in the control computers of CANDn nuclear power stations. It is a network of three computers: the DCC emulator, the dynamic CANDU plant simulator and the testing computer. Shared network files are used for input/output data exchange between computers. The DCC emulator runs directly on the binary image of the DCC software. The dynamic CANDU plant simulator accepts control signals from the DCC emulator and returns realistic plant behaviour. The testing computer accepts test scripts written in AECL Test Language. Both dynamic tests and static tests may be performed on the DCC software to verify control program outputs and dynamic responses
