CNNC Nuclear Power Institute has successfully developed a new type of high temperature resistant electromagnetic coil with a temperature resistance rating of 440
In April, CNNC Nuclear Power Institute successfully developed a new type of high temperature resistant electromagnetic coil with a temperature resistance rating of 440. The newly developed electromagnetic coil has a high temperature resistance level, reaching the world leading level.
Improving the temperature resistance of control rod drive mechanism is always one of the development directions of improving the performance of control rod drive mechanism. For the control rod drive mechanism, the temperature resistance of the whole machine mainly depends on the temperature resistance of the electromagnetic coil.
The successful development of 440 grade high temperature resistant coil can cancel the ventilation and cooling system of the control rod drive mechanism on the top of the reactor, simplify the structure of the top of the reactor, save the installation cost, shorten the construction period, and improve the economy of hualong-1.
At the same time, it also improves the reliability and service life of the whole control rod drive mechanism, thus improving the safety of Hualong I. Through theoretical calculation and test, the control rod drive mechanism with 440 level electromagnetic coil has the ability of long-term operation without ventilation and cooling.
It is understood that in order to further improve the temperature resistance level of the solenoid coil, the professional team of control rod drive mechanism carries out technical research from various aspects such as structure, material, manufacturing process, etc., CNDP overcomes the impact of the epidemic situation by setting up a QC team and a youth commando team, so as to ensure the completion of the project on schedule and with high quality.
Based on the above development and test verification, 440 class high temperature resistant coil was successfully applied to the control rod drive mechanism as a major improvement project, and 440 class high temperature resistant coil was applied to five units of three nuclear power projects.
9 million kilowatts is far beyond the plan: Guangdong will no longer organize the competitive allocation of onshore wind power in 2020
The official website of Guangdong Development and Reform Commission issued the notice of Guangdong Provincial Energy Administration transmitting the relevant matters of the National Energy Administration on the construction of wind power and photovoltaic power generation projects in 2020, which pointed out that the onshore wind power in Guangdong Province has been completed and connected to the grid for about 4 million kilowatts, and the sum of the approved, uncompleted and under construction projects exceeds 9 million kilowatts, which is far beyond the goal of 6 million kilowatts in 2020 as planned by the state In 2020, the competitive allocation of onshore wind power will not be organized any more. In principle, no new centralized onshore wind power projects should be approved by local governments.
Efforts should be made to speed up the construction of projects under construction and strive for more production and grid connection within the year; meanwhile, other approved projects should be actively promoted to speed up the implementation of commencement conditions and start construction as soon as possible, so as to strive for a new grid connection capacity of 2 million kilowatts in the whole province. It is necessary to clean up and cancel the overdue projects according to law, so as to make room for the development of subsequent wind power projects; the projects that are still valid but difficult to start construction within the year can be listed as the reserve projects in the "14th five year plan" period. Please report the clearing and reserve projects to our bureau by the end of the year.
