Abstract
Westinghouse company (WEC) had developed a Nuclear Regulatory Commission (NRC) approved advanced logic system (ALS) platform based on field programmable gate array (FPGA) technology as the next generation 1E class platform for protection and monitoring system (PMS) development for nuclear power plants. In compliance with the requirements of typical PMS functions, a new ALS based PMS is designed by overcoming the restrictions of communication modules etc. The consistency with data communication independence and isolation, deterministic, diversity requirements etc. is analyzed. The evaluations indicate the design meets the requirements and can be applied for coming projects.
Highlights
The rapid development of digital computer technology and the widely deployment in nuclear power plant results in the problem of the high complexity of instrument control system (I&C), which is being paid more and more attentions
After the acquisition of CSI, Westinghouse company (WEC) continued carrying out a lot of licensing jobs and the final safety report was issued by Nuclear Regulatory Commission (NRC) in September 2013
NRC approved that the platform can be used as a solution to solve the problem of diversity and defense in depth for digital safety system, which can be customized for safety system replacement or new safety system development [3]
Summary
The rapid development of digital computer technology and the widely deployment in nuclear power plant results in the problem of the high complexity of instrument control system (I&C), which is being paid more and more attentions. The software common mode failure (CCF) in nuclear power plant digital control system cannot be eliminated completely with the current technology, in the development of PMS, the usage of the specific methods to deal with the problem, such as diversity design and/or diversity actuation system, is a common practice. These methods increase the design, development and licensing difficulties and costs [1]. Based on the successful practice, CIS introduced the ALS to industry as a safety system development platform. Based on the requirements in the Nureg-0800, the consistency with the rules and guidelines for the PMS in terms of data communication independence and isolation, deterministic, diversity requirements is studied
