A method for searching and eliminating potentially false paths of the system is devised as well as a method for taking into account specified constraints on the mutual operation of parallel channels.


When the discharge formation is completed, the main electrodes of the MSGs are shortcircuited by discharges through parallel channels (whose number is equal to the number of bars).


Use of parallel channels in wideband signal recorders


There are parallel channels which are not fully connected in practice, such as Frequency Division Multiplex (FDM or Orthogonal FDM) systems.


Conventional spacetime codes can be used for such parallel channels but not the optimal.

As the size and cost have shrunk, techniques have improved and 'parallel' multichannel receivers are common.

This paper analyses reliability of the protective safety system of a nuclear power plant from the point of view of the probability theory, makes the calculation and comparison of reliability of the singlechannel, parallelchannels, multiplex configuration channels, Kout ofN redundant channels, multiout logic, standbys that are always used in the protective safety system of a nuclear power plant. It is indicated that multiplex configuration channels are ideal logic models of the protective safety system of a nuclear power plant.  本文从概率理论观点出发,分析了核电站安全保护系统的可靠度,计算、比较了核电站安全保护系统中常用的单通道、平行通道、多重型通道、m取K多余度符合、多重输出、备件等逻辑的可靠度,指出了“多重型多余度符合逻辑是核电站安全保护系统的理想逻辑形式”。  Two type of oscillations were calculated using both an eighthcore and halfcore geometric model by RAMONA3B, they are corewide(in phaes) oscillations due to core inlet flow loop oscillations as well as regionwide power distribution oscillations due to outofphase parallelchannel flow oscillationa. Several sensitivity calculations were performed The calculations indicate that amplitude and the excitation threshold are sensitive to operating condition.The calculated period ranged from 2.6 to 2.9 seconds.  用RAMONA3B程序、BWR/4模型及1/8和1/2堆芯的几何形状计算了BWR两种形式的振荡——由于堆芯入口回路振荡引起的堆芯功率(同相)振荡和由于平行通道间流量(不同相)振荡引起的区间功室振荡。对于影响稳定性的一些因素进行了灵敏度分析。计算表明,振荡的激发國和振幅对反应堆的状态很敏感,振荡的频率范围为2.6—2.9秒。  By using the program STEADYLHTR, the stability of twophase flow system of a 200 MW nuclear heating reactor being designed by INET, Tsinghua University, has been studied.

By using the program STEADYLHTR, the stability of twophase flow system of a 200 MW nuclear heating reactor being designed by INET, Tsinghua University, has been studied. This article describes the instability of Ledinegg and multichannel oscillation and its mechanism. A great deal of calculations and analyses for flow characteristics, which are shown by figures and tables, of the 200 MW nuclear heating reactor with natural circulation system have been completed. The results show that the natural circulation flow rate in the 200 MW nuclear heating reactor is slightly increasing with the core inlet temperature rising, under nominal operating conditions the flow has good stability. However, as the core inlet temperature approaches to 155 C at 2. 0 MPa pressure the Ledinegg instability and multichannel oscillation instability will occur in the natural circulation system of the 200 MW nuclear heating reactor.  利用STEADYLHTR程序,对清华大学核能技术设计研究院所设计的200MW核供热堆的两相流动系统的稳定性、并联通道流动不稳定性的现象作了描述和机理分析。对200MW核供热堆自然循环系统流动特性作了大量的分析计算,计算结果以表图形式给出。计算结果表明,①200MW核供热堆自然循环的流量随堆芯入口温度的升高而稍有增加。②额定设计工况下,反应堆的自然循环系统有很好的流动稳定性。③在额定压力2.0MPa下,堆芯入口温度接近155℃时,自然循环系统可能出现莱迪内格不稳定及平行通道不稳定流动。   << 更多相关文摘
