Technical and Economic Analysis of Nuclear Heating Based on HPR1000

Abstract

HPR1000 is China's third-generation nuclear power technology with independent intellectual property rights, and is the main technology choice for the safe and efficient development and mass construction of nuclear power in China. This paper investigated the situation of nuclear heating at home and abroad, combined with the demand of heating and steam supply, analyzed the market demand and commercial layout. The technical feasibility, safety reliability and economic suitability of HPR1000 heating and steam supply are studied and demonstrated. Through the analysis of typical cases, the research results show that the proposed scheme of heating system can meet the requirement of heat source reliability. By adding isolation between the secondary circuit and the heating system, the migration of radioactive materials into the heating system can be effectively prevented and the environmental safety impact assessment is acceptable. Through adaptive modification of the control system, automatic regulation of reactor, steam turbine and heating system can be realized to ensure the safe and reliable operation of the unit. In terms of economy, the economic benefits of HPR1000 heating can be competitive with coal, better than gas. The calculated price level of steam supply also has certain market competitiveness. It provides research support for the follow-up HPR1000 heating project.
