Mentioned in his 2003 report on going abroad for the study of the instrument control system : the abwr power plants currently in operation in the world are only the nuclear power plants that use a similar design, but the scope of their use of dcis it is not as extensive as the fourth nuclear plant, so there is no precedent for the design of some I&c systems and equipment integration.
Regarding the possible risks of the instrument control system, the nuclear group and taipower said that subcontracting does not mean unsafe, and the key point is that the project has an acceptance quality control mechanism in the end. However, it is undeniable that public works with high risk factors such as nuclear power plants do not use the instrument and control system with previous commercial conversion experience, but adopt new technical specifications without actual commercial conversion experience. No wonder it has been questioned and challenged continuously over the years.
In 2014, non-governmental organizations and legislators requested that the instrument control system should pass the inspection of the us nuclear regulatory commission nrc. Taipower only replied that this verification is not necessary, and the instrument Illustrator Art Work control system only needs to be certified and accepted by the taipower commission and a third unit. , and pass the subsequent commercial transfer test.
However, as early as the 31st electric power engineering seminar in 2010, the conclusion of the research report on the update of the digital I&c system of nuclear power plants clearly pointed out that the conditions for selecting a safety I&c system development platform should include the platform approved by nrc, nuclear power plant safety I&c systems update regulatory requirements, safety functions, proven design, reliability, operating experience and scalability.
