YANTAI -- China's first commercial demonstration project for nuclear heating "Warm-U-Clear No.1" recently began this winter's supply, according to its operator State Power Investment Corporation (SPIC).

"Warm-U-Clear No.1" adopts zero-carbon heating technology with completely independent intellectual property rights.

Over the five years since it was put into operation, its heating capacity has increased 36 times from 31.5 megawatts to 1,134 megawatts, and the area where it provides heat has expanded nearly 20 times from 700,000 square meters to 13 million square meters. It serves as an important clean heat source for Haiyang County-level City and Rushan County-level City in east China's Shandong Province.

This year, "Warm-U-Clear No.1" is expected to supply 4.6 million gigajoule (GJ) of clean heat throughout the heating season, saving 410,000 tons of raw coal consumption and reducing carbon dioxide emissions by 760,000 tons.

In this year's heating season, Shandong Nuclear Power Company developed a steam turbine valve which can adjust heating, lifting a single unit's heating capacity by about three times. Each unit is capable of providing heat for 30 million square meters of buildings, which can meet the needs of about five county-level cities.

It is expected to provide clean heating for Qingdao City, east China's Shandong Province, in 2026, and its long-term heating capacity will reach 200 million square meters.
