Assessment of Multi-Unit Emergency Response Capability of Nuclear Power Plants

Abstract After the Fukushima accident, the multi-unit accident has attracted widespread attention in various countries. However, at present, the assessment of emergency response capability generally focuses on a single unit, and with the construction of multiple units at one site, it is necessary to evaluate whether the site has the ability to deal with multi-unit accidents. Therefore, this paper takes a multi-reactor nuclear power plant site in China as an example to evaluate the emergency response capability of the multi-unit accidents from the perspective of the improvement items of the site after Fukushima, the ability to mitigate the consequences of the accident, the management of the multi-unit site, and the response to the multi-unit accident. The ability to mitigate the consequences of the accident will be analyzed from the perspective of the design of HPR1000. In terms of management, each unit at the site is equipped with a basic on-site emergency organization, and regular emergency training and exercise are conducted for staff in different positions. In order to improve and enhance the emergency ability of multi-unit accidents, this paper suggests that the site should clarify the manpower arrangement and specific responsibilities in terms of emergency coordination between units in the event of multi-unit emergency. In terms of multi-unit accidents response, the site is equipped with emergency rescue materials to deal with multi-unit accidents and external support will provide help if necessary. In general, the multi-unit emergency response capability of the site is good, and it can be further improved in the future in clarifying the responsibilities of multi-unit emergency personnel.
