Technical field

The present invention relates to technical field of nuclear power, in particular to a kind of nuclear power unit reactive planning management method.

Background technique

Third generation Advanced passive pressurized water reactor nuclear power technology is mainly by reactor, primary Ioops system and secondary coolant circuit system etc. three A part composition.Nuclear fission is carried out in the reactor core being made of in pressure vessel nuclear fuel.Presurized water reactor is with low dense Contracting uranium is fuel, light-water is coolant and moderator.The heat that nuclear fission is released is by flowing through the high pressure of the primary Ioops system in heap Water takes out-pile out of and transfers heat to the water of secondary circuit in steamer generator.The Steam Actuation vapor wheel generated after water is heated Machine, steam turbine then drive shaft coupling electrical power generators.It is possible thereby to which the energy of reactor most original is split from the core of nuclear fuel Become reaction, the energy for controlling nuclear reactor seeks to the fission reaction of control nuclear fuel.Fission reaction refers to a fissible original Daughter nucleus forms a complex nucleus after capturing a neutron, and complex nucleus passes through an of short duration time (about 10-14S) it is unstable swash After the change stage, two fragments are split into, while releasing the reaction process of neutron and energy.Nuclear power plant is mostly by control at present The appropriate distribution of sub- poisonous substance passes through boric acid concentration and the control control adjusted in primary Ioops coolant to control changes of reactivity The insertion of stick.AP1000 unit controls the power of the assembling unit by adjusting power stick group (M stick), by adjust coolant boron concentration come Compensation fission generate neutron poison (135Xe、149Sm)。

When power grid needs to overhaul or municipal administration maintenance (such as subway maintenance) needs to adjust grid power, dispatching of power netwoks can will be adjusted Degree information is transferred to power plants generating electricity planning authorities, and relevant communication is run control department to unit by generation schedule department With reactor core monitoring technology support sector, suitable reactivity is formulated according to unit relevant information by reactor core monitoring technology support sector Plan.When dispatching of power netwoks is expected changed power, reactor core monitoring technology support sector is manually entered machine by offline software The relevant informations such as power, burnup, the control stick position of group obtain reactive planning book after being simulated, and make for operations staff's reference With can not real-time update;And unexpected changed power is encountered, when power grid emerency request changed power, it can only be monitored by reactor core Technical support department personnel provide help in Site for Unit to cooperate operations staff to carry out unit allocation.

Traditional nuclear power unit reactive planning management method step is comparatively laborious, can not intuitively monitor that critical data is come Nuclear power unit is regulated and controled, accuracy is poor, does not have real-time, so that reactivity control execution efficiency is low, completely not The rapidity requirement that nuclear power turbine-generator unit is quickly intervened is adapted to, the operational efficiency of power plant is influenced.

Detailed description of the invention

Present invention will be further explained below with reference to the attached drawings and examples, in attached drawing:

Fig. 1 is the flow chart of nuclear power unit reactive planning management method provided by the embodiment of the present invention;

Fig. 2 is function management interface view provided by the embodiment of the present invention.

Specific embodiment

In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and It is not used in the restriction present invention.

As shown in Figure 1, the embodiment of the present invention is illustrated by taking AP1000 nuclear power unit as an example, the present embodiment provides a seed nucleus Motor group reactive planning management method, comprising the following steps:

The original state for the nuclear power unit that S1 is currently running by nuclear power unit tool platform and the detection of reactor core detection device, The original state includes the initial boron concentration in the initial power of the assembling unit and reactor core.

S2 is according to the middle power of generation schedule department or power grid informing, middle power time started, middle power platform Residence time, target power and target power time set the power of the assembling unit and drop power speed in each changed power stage Rate, and generate changed power line chart.The data of drop Power Ratio and the power of the assembling unit in each changed power stage can pass through work Tool platform obtains in real time.General dispatching of power netwoks may have multiple middle power platforms, the power of the assembling unit need with middle power or Target power is consistent;It drops Power Ratio to need to be set according to the state and grid requirements of unit, the drop in the present embodiment Power Ratio is not more than 5 the percent of full power per minute, to avoid damage nuclear power unit.

Boron concentration, required needed for S3 calculates nuclear power unit reactor in each middle power platform according to original state At the beginning of the boric acid of addition or the volume of water and boronation/dilution, and generate boronation/dilution volume histograms.

S4 is by original state, changed power line chart, boronation/dilution volume histograms, the machine in each changed power stage The body of the boric acid or water that are added needed for group power, drop Power Ratio, middle power platform residence time, each middle power platform Boron concentration needed for reactor is shown in same function at the beginning of long-pending and boronation/dilution, when each middle power platform It is specific as shown in Figure 2 in administration interface.

Changed power line chart can make operator be understood more intuitively time for needing to carry out changed power operation with And drop Power Ratio, boronation/dilution volume histograms can make operator that boronation/diluted amount and note be understood more intuitively The angle of incidence carries out accurate, regulation in real time to nuclear power unit to realize, improves execution efficiency.

S5 controls the boron concentration in nuclear power unit reactor according to the content and data of function management interface display.In power The position of control rod is controlled during variation by reactor power control system.During boronation/diluted, according to drop Power Ratio, control stick position and unit realtime power control boronation/amount of dilution.It is obtained in reactor by tool platform Coolant temperature, and the temperature is compared with actually measured coolant temperature, when the two temperature difference be more than certain threshold value (such as ± 0.83 degree) when start dilution or boronation, with reach it is optimal dilution or boronation effect.

S6 will drop Power Ratio and be set as link key and link to drop power operation platform.It can be made by the way that link key is arranged Operator directly directly links at function management interface and enters to drop power operation platform, carries out drop power control to unit, makes Operator is more intuitive, fast and accurately nuclear power station steam turbine power generation unit is controlled and intervened, and guarantees nuclear power station steam turbine power generation The safety of unit.

The embodiment of the present invention is described in conjunction with attached drawing above, but the invention is not limited to above-mentioned specific Embodiment, the above mentioned embodiment is only schematical, rather than restrictive, those skilled in the art Under the inspiration of the present invention, without breaking away from the scope protected by the purposes and claims of the present invention, it can also make very much Form, all of these belong to the protection of the present invention.
