Fast Reactor R&D
The development of sodium-cooled fast reactors (SFR) in China started in the 1960s. In 1987, the China Experimental Fast Reactor (CEFR) project was included in the National High Technology Research and Development Program (or "863 Program"). The project was coordinated by CNNC and implemented by CIAE. The reactor was connected to the grid on July 21, 2011, with a rated power of 20 MWe (65 MWt). The implementation of this project enabled the development of a set of codes and standards for fast reactors. A software library for SFR design and safety assessment has been established. Dozens of experimental devices have been developed for research in the fields of fast reactor physics, thermal engineering, mechanics, safety, materials, nuclear fuel and equipment building, with localization rate reaching up to 70%.
Under a "three-step" (experimental – demonstration – commercial) SFR development program, the construction of the China Demonstration Fast Reactor (CFR600) started in Xiapu, Fujian Province in December 2017, and the project has now entered its installation phase. Its completion will lay the groundwork for the development of commercial MOX-fueled SFRs.
快堆技術(shù)研發(fā)
中國鈉冷快堆技術(shù)研發(fā)起步于 20世紀(jì) 60年代。 1987年,中國實驗快堆( CEFR)項目被納入國家“ 863”計劃。該項目由中核集團(tuán)組織,中國原子能科學(xué)研究院具體實施,于 2011年 7月 21日實現(xiàn)首次并網(wǎng)發(fā)電,額定功率 20MWe(65MWt)。通過項目實施,建立了一套快堆標(biāo)準(zhǔn)規(guī)范體系,開發(fā)了一套鈉冷快堆設(shè)計和安全評價的軟件庫,建成可開展快堆物理、熱工、力學(xué)、安全、材料、燃料、設(shè)備等方面研究的幾十套實驗裝置,設(shè)備國產(chǎn)化率達(dá)到 70%。
按照鈉冷快堆實驗堆—示范堆—商用堆“三步走”發(fā)展計劃, 2017年 12月中國示范快堆( CFR600)在福建霞浦開工建設(shè),目前已進(jìn)入設(shè)備安裝階段。示范快堆的建設(shè)和運(yùn)行,將為使用 MOX燃料的鈉冷商業(yè)快堆的發(fā)展奠定基礎(chǔ)。
