Fuqing Nuclear Power Plant Reactor Protection System has designed emergency control panel ECP, which is used to deal with the risk of loss of digital automatic protection functions due to common software failure. ECP is designed and implemented by analogy technology, which can bypass the computerized DCS system and use buttons, indicator lights, relays and other devices to achieve system-level protection functions. In practical engineering applications, it is found that the current ECP can not meet the requirements of post-accident control in some specific circumstances. Through the analysis of system design and accident management procedures, two design improvements are listed, compared and analysed, and the optimal improvement is given in this paper.
