Westinghouse has promised to transfer nuclear island tec hnology and system engineering,and to provide te chnic al spec ifica tions and instruc tion ma nual for the main equipment,as well as foundation design for the main equipment of nuclear steam supply system.The design and manufacturing technologies of other equipment will be provided by Westinghouse contracting group,according to the agreement between the State Nuclear Power Technology Corporation (SNPTC)and Westinghouse.
The items already concluded and being implemented include reactor pressure vessel,steam generator,reactor internals and control-rod driving mechanism,squib valve,reactor coolant pump,overhanging unloading machine and refueling machine,containment etc.,as well as fuel element,nuclear-grade zirconium material and instrumentation &control equipment etc.
Although heavy forgings,main pipeline and key nuclear-grade valve,etc.,which are hard to be made in China,are not included in the transfer scope,research for localization of these equipment has already been carried out in domestic nuclear power equipment manufacturing enterprise s,under the vigorous support of National Development and Reform Commission and the Ministry of Science and Technology.U
p until now,great progress has been achieved.
According to the preliminary statistics,the localization
rates of the four units can be 30%,50%,60%and 70%,respectively,with the average rate reaching 50%.

Currently,the localization rates of main equipment for CPR and generation 2+in China have reached over 75%.With the localization of the four units,China can master the key te chnologie s of the main equipment for AP1000.Starting from the fifth set of equipment,the localization of AP1000can almost be realized.For nuclear main pump and nuclear-grade safety valve,China will realize their localization by cooperating with foreign competent companies.This work is now in progress,and is believable to be completed in the near future.
For the time being,China has formed three major nuclear power equipment manufacturing bases in Northeast China,Sichuan and Shanghai,and large manufacturing bases for castings and forgings,and pressure vessels.Meanwhile,in order to solve the transportation of large nuclear power equipment,Harbin Boiler Company Limited,Shanghai Boiler Company Limited and Dongfang Boiler Co
mpany Limited have set up estuary bases in Qinhuangdao,Linga ng of Sha ngha i a nd Nansha of Guangdong,respectively.The equipping levels of the bases have all reached world standard.

To promote new energy development by top experimental research
Mr.Liu Zhenya,general manager of the State Grid and Mr.Fu Zhifang,executive vice governor of Hebei Province together with their colleagues jointly inspected the development of new energy project in Zhangbei County,Zhangjiakou City,Hebei Province.At Manjing Wind Farm,Mr.Liu Zhenya studied the long-term development program,the accessibility into grid and the related projects in vicinity of the wind farm.Presently,Zhangjiakou City is the rst dual GW-class wind farm base in China.The Manjing Wind Farm has a planned total capacity of 200MW,and is so far the one with largest single capacity in the country.On the site of the testing base for Wind Power Research &Test Center and PV/wind hybrid system
demonstrative project,after listening to the report concerning sites selection and project schedule,Mr.Li
reactor pressure中文
u Zhenya gave his opinions on the development and use of clean energy,including renewable energy.
According to presentations,a simulation research platform,a movable testing platform and a wind power testing base will be built in the center.In the future,this center will have the capability to test from wind power simulation research,wind power prediction to wind power dispatching decision-making.It will also be able to authenticate wind power units and wind power grid connection in accordance with international standards.At present,the Solar Power Generation Research &Test Center is in preparation stage.
