摘要

The Fuqing, Fangjiashan and Hainan D3 assessment has demonstrated that there is sufficient diversity and defense-in-depth to cope with a postulated SWCCF to the Tricon digital platform in the RTS, ESFAS and the augmented quality systems. It has been determined that even with a postulated SWCCF there are adequate defenses and diversity in the digital I&C architecture to meet the applicable acceptance criteria when supplemented with a DAS design that includes the functions of the existing ATWT systems as well as those described in the final D3 report. The DAS provides non safety-related RTS functions, ESFAS functions, and operator displays and alarms. In the DAS, both automatic and manual means are provided to trip the reactor and actuate selected ESFAS functions given a SWCCF to the Tricons. The DAS is specifically implemented in hardware and software that is diverse from the primary RTS and ESFAS.
