The lfg collection and utilization is company know how that is demonstrated at a site in meizhou , guangdong province that currently collects 2000 m3 hr of gas and treats all the leachate from the site , 2 mw electrical power plant will be installed on the site to utilize the collected gas soon 该技术在中国梅州市进行了试点，现回收沼气能力为2000立方米小时，同时循环处理该填埋场的全部渗滤液，并计划近期在该填埋场建设装机容量2兆瓦的发电厂，使用回收的沼气发电。
The ratio of ma added to the mox fuel is studied . the neutronics characteristics of ma transmutation , and the transmutation and burning efficiency of the modular fast reactor are calculated . the role of the modular fast reactor to buffer the growing of ma in china and the reduction of radiotoxicity of nuclear waster via multiple recycling of ma in the modular fast reactor are calculated 主要论述随着我国压水堆核电站装机容量和运行堆年的增加，乏燃料中ma总量增长趋势；模块快堆的堆芯概念设计方案；在不改变模块快堆堆芯设计的前提下， mox燃料中添加ma和稀土核素对堆芯中子学性能的影响以及模块快堆的嬗变效率；模块快堆对减少我国ma总量的作用；模块快堆产生的最终核废物的长期放射性毒性随时间的变化等。
Based on the project scale argumentation of letan hydropower station , the paper briefly introduces the main results of scheme ' s technical & economical comparison and the main factors of scheme option in the option and design stage of the normal storage water level and installed capacity , as well as the evaluating opinions given by the specialist group of project proposal evaluating committee ; the main technical characteristics for similar project scale argumentation are summarized up according to the project scale design argumentation of letan hydropower station 摘要通过乐滩水电站工程规模论证，简述该工程正常蓄水位选择和装机容量选择设计阶段方案技术经济比较的主要成果、取舍方案的主要因素、以及项目建议书评估会专家组的评估意见；并根据乐滩水电站工程规模设计论证总结类似工程规模论证时的主要技术要点。
Static benefits are generated from peaking and valley - filling , which are further divided into capacity benefits and coal saving benefits . dynamic benefits come from its fast starting and flexible operation , including frequency regulation , synchronous condenser operation , fast coverage of steep load gradient and synchronous spinning reserve . as for the calculation of static benefits of pumped storage plant , the alternative coefficient method is normally adopted at present 目前在抽水蓄能电站的静态效益计算中，一般采用替代系数法，即用抽水蓄能电站的装机容量乘以容量替代系数( 1 . 05 1 . 1 )计算抽水蓄能电站的替代容量；用抽水蓄能电站的发电量乘以电量替代系数( 1 . 05 )计算替代电站的发电量，再根据循环效率的大小计算抽水蓄能电站的燃料消耗。
