Study on Key Technical Issues of Marine Environmental Safety Assessment of the Floating Nuclear Power Plant

Abstract

As a civil nuclear facility combining the organic innovation of marine engineering and nuclear engineering, the Floating Nuclear Power Plant (FNPP) is significantly different from the existing land-based fixed Nuclear Power Plant (NPP) because of the particularity of its shipborne platform and marine operating environment, although it has the general nuclear characteristics of the Small Modular Reactor (SMR). The existing national nuclear safety regulations and regulatory requirements are mainly based on onshore NPPs, so the applicability for the environmental safety assessment of the FNPP is limited. In this paper, through the study of the FNPP on the applicability of environmental safety supervision regulations and assessment requirements, the marine environmental characteristics and site suitability, the feasibility of radioactive waste treatment and discharge, the rationality of environmental monitoring scheme and implementation, the accident consequences and risk controllability, and the key technical issues of the marine environmental safety assessment of the FNPP are proposed, which can provide references for the environmental safety research and supervision of the FNPP.
