On March 13, 2021, 21 points 42 points, "hualong" number one demonstration project fuqing nuclear power unit 6 B column of the emergency diesel generator set and stable operation at the rated speed 600 r/min platform, the nuclear engineering in fuqing project commissioning department, engineering department, two or three companies and shan wood joint check the various parameters of the normal diesel engine manufacturers, marked by the nuclear engineering in the total package of hualong demonstration project number one finally made the first successful launch an emergency diesel generator set!
The emergency diesel generators for units No. 5 and No. 6 of Fuqing Nuclear Power Plant are supplied by Shaanxi Diesel Heavy Industry Group, which are large-scale domestic systems and equipment for demonstration projects.As 6 machine hot try one of the prerequisites, 6 db special tasks major and urgent time limit, the team set up for this LiuPeng (debug), WuHanSheng (project management) and Shao Dewei (23) as the main coordinator "trio", "three groups" group held a meeting every day, to establish effective coordination WeChat group of leadership, and organize various units strictly implement fuqing unit 5 and 6 da civil engineering construction, installation, commissioning and operation experience, to bring forward a series of changes in place, in the construction process, debugging in check is optimized.Through the whole-process tracking and coordination of the equipment complete set center, "jam" items such as AVR regulator, valve and so on were delivered according to the on-site demand time, which made the system equipped with debugging intervention conditions.The commissioning test team has been fully involved since mid-January 2021 to carry out the 6EMQ09/10/13 test, and the commissioning period will be parallel to the main operation of oil flushing and pipeline restoration as far as possible.On March 7th, 6DB started to feed fuel for the first time, and tested 3 fuel pumps. After five days of intense test, leak checking and shortage eliminating, the fuel loop of the diesel generator set finally ran smoothly, and the "last kilometer" before the first start up was completed.
On the morning of March 13th, the first start will be held on time before the first start. After nearly six hours of system online, inspection and operation ticket execution, the diesel engine officially starts the test.According to the regulations, start the engine mode only, maintain the speed platform at 300 RPM and 600 RPM respectively, and then start the electrification mode on the two speed platform to check the normal operation of the diesel unit.After the completion of the first start, the debugging team will carry out a series of debugging tests, such as single row fast start, no-load excitation, diode phase break, false and true synchronous connection, steady state operation and performance acceptance, etc.The 6EMQ will not be officially ready for use until all tests pass.
Boron containing polyethylene is one of the most commonly used anti - neutron materials in neutron shielding. Because of its high strength, uniform density, acid and alkali corrosion resistance and superior neutron shielding performance, this material has been widely used in neutron shielding protection.
HONGBAO CHEM specializes in producing borated polyethylene sheet, lead boron polyethylene sheet and other products. We can do CNC processing according to the drawings. The boron content varies form 2% to 50%. Welcome to contact us !
