Event 2: The Technical Appraisal Meeting of KIT/KPS System for Daya Bay NPS

The Technical Appraisal Meeting of KIT/KPS System for Unit 1&2 of Daya Bay Nuclear Power Station
28 August, 2009
Daya Bay Nuclear Power Base
National Energy Administration (NEA)
China Machinery Industry Federation (CMIF)
CTEC and Daya Bay Nuclear Power Operations and Management Co., Ltd (DNMC)
Expert Team
Authoritative experts from China nuclear I&C industry
Leaders and delegates from National Development and Reform Commission (NDRC), NEA, CMIF, Nuclear and Radiation Safety Center (NSC) of Ministry of Environmental Protection (MEP), China Guangdong Nuclear Power Group (CGNPC) and China National Nuclear Corporation (CNNC) and etc.

Appraisal Result:

The expert team agreed that the successful on-site operation of the system was a breakthrough of the KIT/KPS design and manufacturing technology for mega-kilowatt nuclear power units. The refurbishing system developed based on CTEC’s own intellectual property has all its main performance indicators reach the advanced level worldwide of similar products. In the end, the committee identified it had passed the technical appraisal.
Project Revew:
I&C system is the heart of the main control room in a nuclear power station (NPS), of which the digital data acquisition and centralized processing system (KIT/KPS) is a crucial part. It's mainly responsible for the operation data acquisition and centralized processing for the main equipments in NI and CI. It can provide the control room operator with various information that required by normal operation, accident diagnosis and post-incident analysis. In this way it can ensure the safe operation of a NPS.
The identified KIT/KPS refurbishing project for Daya Bay Nuclear Power Station was carries out by CTEC and DNMC. After two years R&D, the KIT/KPS refurbishing work of Unit 2 and Unit 1 was completed respectively in November 2008 and May 2009. Until now, both of the two units' digital KIT/KPS systems have been running stably without any failure.


Project Meaning:


The KIT/KPS refurbishment for Unit 1&2 of Daya Bay Nuclear Power Station is the largest nuclear power I&C system digitization project in the country. The refurbishing system not only realized all the functions of the original KIT/KPS but also added more advanced application functions. Another point deserved to be highlighted is the amazing refurbishing speed. Only 16 days was spent from the equipments removal (including the removal of the original cables/equipments, the laying of the new cables and the installation of the new equipments) to the trial operating of the system. The success of the project symbolizes CTEC has stepped into a new stage in the aspects of system design, manufacturing, project management, onsite implementation and control.

Now in nuclear power DCS industry, CTEC has formed a comprehensive mechanism from overall design, detail design, system integration and testing, product R&D and manufacturing to system installation, commissioning, maintenance and equipment management.
