Implementation principles of FPGA-based ESFAS for Kozloduy NPP

摘要

In February 2008 Research and Production Corporation (RPC) 'Radiy' won a tender for delivery of six Engineering Safety Feature Actuation Systems (ESFAS) to Bulgarian NPP units Kozloduy-5, Kozloduy-6. The first of those ESFASs successfully passed Factory Acceptance Testing (FAT) in July 2008. Mounting of the first ESFAS at the site (ESFAS-2 of Kozloduy-6) has been started in September 2008. Mounting before commissioning should be finished in extremely short period (about one month). This paper objective is to discuss structural peculiarities as well as testing and commissioning results of FPGA-based ESFAS for Kozloduy NPP. The following points are included in this paper content: 1) ESFAS structure and software-hardware configuration; 2) peculiarities of ESFAS function implementation on the base of FPGAs; 3) ESFAS verification and testing.
