China has decided to speedup the nuclear power development. It is programmed that the nuclear power capacity will reach 40 GWe in 2020 and envisaged 60 GWe and 240 GWe in 2030 and 2050 respectively. The basic strategy of PWRFBR matched development with Fast reactor metal fuel closed cycle for a sustainable and quick increasing nuclear energy supply is adopted. Another strategy also decided is that the partitioning and transmutation of MA will be realized using fast burner and ADS.The fast reactor engineering development will be divided into three steps: China Experimental Fast Reactor (CEFR 65 MWt/20 MWe), China Prototype/Demonstration Fast Reactor (CPFR/CDFR ≥ 1 500 MWt/600 MWe) and China Demonstration Fast Breeder Reactor (CDFBR 1 000~1 500 MWe). The CEFR is under installation and preoperation testing with it’s first criticality planned in 2009. The design study of CPFR is just started in 2006. Recently a discussion for the second step is under way to faster the fast reactor development by a larger than 600 MWe CPFR and as a role of CDFR.  相似文献

Qinshan Phase Ⅲ (PHWR) Nuclear Power Plant, the first commercial heavy water reactor nuclear power plant in China, was the biggest trade project performed between the governments of China and Canada. As the owner, the Third Qinshan Nuclear Power Company (TQNPC) persisted in independent innovation management during the project construction, commissioning and selfdependent operation, efficiently realizing the three controls of the project, i.e. quality control, schedule control and investment control, and persisted in technical improvement on the basis of digestion and absorption of CANDU6 technology to improve the unit safety and reliability. The project construction practice has helped China’s nuclear power project management to becomeprogrammed, computerized, standardized and internationalized management from the existing basis. After completion of the project, with unit safe and steady operation as the prerequisite, TQNPC performed several technical modifications and innovations to continuously improve the unit performance. In the area of staff development, TQNPC paid much attention to cultivation of corporate culture, strengthed staff training and built up a good circulating mechanism with staff training and project construction promoting each other. Further to “Zero Breakthrough” and a new step forward of locolization successfully realized in Qinshan Nuclear Power Plant and Nuclear Power Qinshan Joint Venture Company, the improvement and developemnt of nuclear power project management level in Qinshan Phase Ⅲ (PHWR) Nuclear Power Plant provided reference for promotion of nuclear power development in China and standardized management of introducing large imported project.  相似文献

The present study deals with the effect of negatively charged ions on the ceramic coating formation on 2024 aluminium alloy during microarc oxidation (MAO) process. On the basis of the experimental results, two steps (the formation of an incipient film without arc presence and the growth of a ceramic coating with arc discharge) of MAO process have been observed. For comparison, four different negatively charged ions studied. It is proved that negatively charged ions strongly participated in the formation of an incipient film with high impedance value at the first step. The growth of ceramic coating depends on the combination between Al of the substrate and O from the electrolyte, and the negatively charged ions are little consumed. As an anodic oxide coating is prepared on the sample surface instead of the incipient film, the first step occurs easily and the growth of ceramic coating is accelerated. Furthermore, the mechanism of negatively charged ions in the formation of the MAO coating has been proposed.  相似文献

Launching vertical shiplift is a type of shiplifts which have the advantages in characteristics of dynamics and statics,safety and simplicity in operation. But their applications are limited as the scales of mechanical equipments are too large. This paper puts forward the principle of minimization of the equivalent load for the general layout design of launching vertical shiplifts,based on the analysis of the load probability of the main hoists and their key mechanical equipments. The principle aims at determining the optimal weight of counterweight so that the equivalent loads of the main hoists of shiplifts are minimized,and larger ships are permitted to pass through. The theory and method presented in this paper have been applied in the design of the first step and third step shiplifts of the Goupitan Hydro Power Station. This has resulted in the breakthrough of the design and manufacture of launching vertical shiplifts so that the ships with tonnage of 500 t can pass through hydro dams for this type of shiplifts,comparing with the largest launching shiplift in Yantan Hydro Power Station with the 250 t shiplift.  相似文献

The civil aviation industry has made rapid development with the continuous growth of China's economy. At the same time ,the airline companies buy more and more civil aircrafts.This phenomenon will lead to a big flying density ,which will make airport management become more complex.This paper first introduces the characteristic of security programs before flight and the single code network plan, and then put the security programs before flight into the single code network plan to find out the key route and calculate the guarantee period. Finally, we analyse the programs according to the guarantee period and critical route.It not only provides a support for administrator, but also we present a reasonable methods to reduce the guarantee period.  相似文献
