The problem of the shutdown or power reduction of multiple units is highlighted

On one side, it is the world's first in the construction of the unit. On one side, it is in the process of running or shutting down the power of the unit. After abandoning the light, abandoning the wind, and abandoning the water, the nuclear problem gradually becomes apparent.

Recently, China's nuclear power industry association, in the first half of this year the domestic nuclear power operation shows although nuclear generation than the same period in 2015 increased by 26.58%, total Internet charge and a 26.02% increase over the same period in 2015, but the nuclear power equipment in the first half of the average using the average utilization rate of hours and nuclear power equipment, only 3335.35 hours and 76.36%, respectively, with the same period last year decreased by 183.8 hours and 4.74% respectively.

The utilization of nuclear power equipment is reduced

"Daily economic news" reporter found, the current domestic in shipment with 30 nuclear power units, there are 12 units of nuclear power equipment utilization on average less than 70%, except for a few units for refueling, overhaul and other reasons, the rest are all at the request of grid, suspended or drop power operation.

Data show that in the first half of this year, nuclear power equipment for the lowest average utilization rate of red river nuclear power plant, unit 1 and unit 2 the utilization rate of only 55.72% and 55.72% respectively, while the utilization rate of unit 3 is more low, only 38.14%.

According to the report, the number 1 unit underwent a major change in the middle of February to the end of march, and was in a standby state in the middle of may to early June.Unit 2 should be on standby for the power grid during the Spring Festival in February, and the seasonal shutdown in early April and early may;Unit 3 was in seasonal suspension for more than three months from January to June.

Besides liaoning hongyanhe nuclear power plant, zhejiang qinshan, fujian fuqing, ningde, guangdong yangjiang and hainan changjiang and other nuclear power bases have all appeared similar situation.It is worth mentioning that the red river nuclear power units in winter heating season to make way for the cogeneration of liaoning province thermal power, cannot ManFa, the situation in the domestic nuclear power operation is rare in history, caused the industry and government attaches great importance to."Although there is no standard for average utilization of equipment, the average equipment utilization rate is less than 75%, and the profit pressure on nuclear power plants is very high."A nuclear power station staff told reporters that the current situation of the whole power equipment utilization hours are falling, liaoning province and fujian province situation, it also means not take so much electricity grid, but for nuclear power plant, originally can run at full capacity, now drop power operation or shutdown, the economic benefit must be discounted.

Along with the economic growth and a fall in demand for electricity, nuclear power given problems are increasingly apparent, as the base load power status by unprecedented challenges, and new electric change, nuclear power face more complex environment in the competition.The country during the two sessions this year, including the chairman of the board of CGNPC He Yu three nuclear state head joint proposal, should from the policy clear way to run a nuclear power according to the basic load, to ensure that nuclear power ManFa, multiple.It seems to many people in the nuclear power, nuclear power long-term power operation reliability and even shut down will produce nuclear fuel lower, key equipment fatigue wear, increase the risk of radioactive waste and wastewater.The itu, said an expert with the more weak electricity demand, in terms of features, nuclear power to do the adjustment can be appropriately, but need to comprehensive security, economic benefits and market demand, the proportion of clean energy sources, etc.

Cross the province to become a way out?

"There has been no approval for a nuclear project this year, which is directly related to the domestic environment."A nuclear power official told reporters.Nuclear power has been expected to approve six to eight nuclear power units a year since it restarted last year, according to a number of nuclear experts.But this year, the pace of approvals for nuclear power is down, and if demand is high, the number of nuclear plants reviewed annually will naturally increase, and vice versa.In response to the surplus of power, the country has begun to study corresponding countermeasures.On July 11, national energy bureau announced the "about promoting the coordinated development of the northeast electric power opinions" (hereinafter referred to as "opinions"), is proposed to speed up the construction of power transmission channel, control of thermal power and wind power construction rhythm and so on several big tasks.

"Opinion" also mentioned above, accelerate the xu existed nuclear north channel out a feasibility study work, combined with "much starker choices-and graver consequences-in" power planning, put forward feasible xu existed nuclear power given scheme, research as a whole new possibility to the northeast electric transmission.In the first six months of this year, there were 16 provinces with a higher growth rate than the national average (2.7 per cent), according to the China electricity association.The personage inside course of study, called for many provinces have a certain demand, the national nuclear power given policy across the province related departments should be clear as soon as possible, increase the scale of power to be delivered to the outside, to effectively solve the problem of nuclear power given.Had a number of experts say, across the province given play to the initiative of the local governments and enterprises, to explore from bottom to top, find several given potential and market competitive technical route, the government should publish a pragmatic policy, not only pay attention to the given end, from the construction of the resource.

People argue that the nuclear power plants, even given across the province, I am afraid, it is difficult to solve, because other provinces power surplus phenomenon will gradually appear, and there may be a problem, local protectionism "power protection is closely related to the local GDP, across the province given may not be the only way out."
