The Nuclear Safety Commission (NSC) completed the safety review and ultrasonic flowmeter (UFM) inspection for the measurement uncertainty recapture (MUR) power uprate project of nuclear power plants last year (2008) and gave the Chinshan (1st) Plant and Maanshan (3rd) Plant the green light to proceed. These MUR power uprate projects contributed to the increase in nuclear power generation by about 32.4 GWh in 2008, ensured nuclear safety to protect public health, and reduced carbon emission to slow down global warming.
The topmost concern of the nuclear power plant operation is safety. In the design stage, the maximum thermal power output of nuclear reactor for safety analysis is set at 102% of the rated thermal power. This 2% margin takes into consideration the possible inaccuracy of feedwater flow measurement in the calculation of power. As technology advances, part of the margin reserved in the original design could be released with the use of advanced UFM to achieve power uprate and increases power generation without additional safety concern. This is termed "measurement uncertainty recapture (MUR) power uprate."
Nuclear power is a "low carbon" source of energy. Increasing the power generation of nuclear power plants can help cut down the reliance on fossil fuel power generation. In evaluating the MUR power uprate project of the nuclear plants, NSC took a professional and prudent approach to review the safety analysis, and sent staff abroad to check on the laboratory verification process. NSC also conducted site inspection when the UFM was installed at the nuclear power plants.
The Unit II of Chinshan Plant completed the MUR power uprate on July 9, 2008, increasing its output by 6 megawatts and power generation by 24 GWh in 2008. The Unit II of Maanshan Plant completed the MUR power uprate on December 2, 2008, increasing its output by 12.4 megawatts and power generation by 8.4 GWh in 2008. The Kousheng (2nd) Plant has completed the power uprate for two units in 2007 to increase power output by 20 megawatts and boost power generation by 158 GWh each year. All together, the MUR power uprate projects, increased Nuclear power supply by 190 GWh in 2008, which contributed to carbon emission reduction by 120,000 tons based on CO2 emission factor of 0.637 kg per kWh power generated by fossil fuel power plants. It is part of our efforts to slow down global warming and promote sustainable environmental development.
The Unit 1 of Chinshan plant completed power uprate on February 24, 2009, increasing its output by 6 megawatts. The Unit 1 of Maanshan plant is expected to complete in mid-2009.
