Shandong Nuclear Power Company (SDNPC) – a subsidiary of State Power Investment Corporation (SPIC) and the owner of Haiyang plant – announced on 15 November that, following a few days of trial operation, the demonstration district heating system had officially been put into operation.
The system extracts non-radioactive steam from the secondary circuit of the two Haiyang AP1000 units, which is then fed through a multi-stage heat exchanger in an on-site heat exchange station. This heat is then fed to an off-site heat exchange station belonging to local thermal company Fengyuan Thermal Power, from where heated water flows through municipal heating pipes to consumers.
