Abstract:
Reactor instrument and control system is an important part in nuclear power plants.Reactor protection system is 1E classified equipment of which hardware platform and developed technology are the key points.All 1E classified equipments were purchased from foreign countries in on-built or on operating power plants in China.The digital platform X86,researched and developed by NPIC,is composed of the controller,intelligent I/O and high speed bus,and satisfies the rules and functional requirement,and pass different types of tests.This platform could become one of the solutions as 1E digital platform for digital nuclear power plant.
