In order to better understand the above technical scheme, in conjunction with appended figures and specific embodiments to upper
State technical solution to be described in detail, it should be understood that the specific features in the embodiment of the present invention and embodiment are to the application
The detailed description of technical solution, rather than the restriction to technical scheme, in the case where there is no conflict, the present invention are implemented
Technical characteristic in example and embodiment can be mutually combined.
First, please refer to Fig.2, it is described an embodiment of the present invention provides a kind of nuclear island water system container rapid drainage method
Rapid drainage method includes step：
S1, determine to treat the pressure-bearing scope of the nuclear island water system container of draining, is modeled based on the pressure-bearing scope and carries out theory
Calculate, to determine the safety drain pressure of the container, and inflated to the container, so that the pressure increase inside the container
To the safety drain pressure；
S2, the Quick drainage pipeline progress draining for opening the container.
Wherein, inflated to the container, be specially：By the public compressed air distribution system of nuclear island (SAT) to the appearance
Device is inflated, so as to ensure that the container has lasting source of the gas.
Above-mentioned nuclear island water system container is mainly the large and medium-sized container in nuclear island water system.In specific implementation process,
Gas ducting and the other pipelines different from the gas ducting are provided with the container, before being inflated to the container, institute
Rapid drainage method is stated to further include：The other pipelines of whole with the reservoir are closed, so that the container is by described
Gas ducting is in air-tight state when inflating.Wherein, other pipelines include gauge pipe, and the purpose for isolating the gauge pipe is
Internal pressure damages instrument higher than the range of instrument on gauge pipe after preventing container inflation.
In specific implementation process, in container Quick drainage, in order to timely processing container discharge substantial amounts of water,
Before being inflated to the container, the rapid drainage method further includes：For the container, the Quick drainage pipeline is set, and will
The Quick drainage pipeline guides to the hydrophobic drainage system of nuclear island (RPE) melt pit, so that water is discharged into the melt pit by the container；Its
In, the Quick drainage pipeline is temporary pipeline.Since nuclear power plant equipment security requirement is very high, for in-service nuclear power station
Building for each facility must all record certification and meet safety standard, and therefore, the Quick drainage needs to debug in nuclear power station
Apply for interim special facilities (TSD) in management system, and put up " TSD labels ", can just come into operation.
For the ease of application scheme is specifically described, below by taking safety injection tank as an example：
Corresponding to above-mentioned steps S1, first, by inquiring about nuclear power plant equipment operating maintenance handbook (EOMM), middle pressure peace is known
It is 4.55Mpa to note case highest operating pressure, i.e., the pressure-bearing scope of the safety injection tank is (0~4.55) Mpa；Then, based on the pressure-bearing
Scope modeling carries out theoretical calculation and incorporation engineering practical experience, the safety drain pressure of the container is determined, to ensure
State container Quick drainage and can will not occur accident under the safety drain pressure, herein, the peace of the safety injection tank be calculated
Full draining pressure is 200Kpa.For different containers, its pressure-bearing scope and safety drain pressure differ.
Further, corresponding to above-mentioned steps S2, in specific implementation process, two kinds of pressurising drainage patterns can be used to carry out
Container draining：
1) container carries out draining under the initial pressure of safety drain pressure, i.e. step S1 and S2 is specially：Pass through inflation
Pipeline is inflated to the container, so that the pressure increase inside the container, monitors the container in real time during inflation
Internal pressure；When pressure inside the container increases to the safety drain pressure, isolate the gas ducting to stop
For the container pressurising, so that container draining under the initial pressure of the safety drain pressure；
2) please refer to Fig.3, container draining under the constant pressure of safety drain pressure, i.e. step S1 specifically includes sub-step
Suddenly：S11, the pressure-bearing scope for determining the container, are modeled based on the pressure-bearing scope and carry out theoretical calculation, to determine the container
Safety drain pressure；S12, inflated by gas ducting to the container, so that the pressure increase inside the container, at the same time
The pressure inside the container is monitored in real time；S13, the pressure inside the container increase to the safety drain pressure, and
When opening the Quick drainage pipeline progress draining of the container, the gas ducting is kept to be in open mode, while prison in real time
The pressure inside the container is surveyed, and the inflation of the container is adjusted based on the pressure inside the presently described container monitored
Amount, so that the pressure inside the container maintains the safety drain pressure.
With reference to above-mentioned safety injection tank, container draining is carried out according to above-mentioned 1st kind of pressurising drainage pattern, in the initial of 200KPa
Draining under pressure, drained water when the used time about 4 is small, in the process, with the gradual discharge of dampening, the pressure in container can gradually subtract
It is small, since container bottom is elliposoidal (as shown in Figure 1), there is residual water not discharge.According to above-mentioned 2nd kind of pressurising drainage pattern
Container draining is carried out, under the constant pressure of 200KPa, is simulated by the hydraulic formulas such as Bernoulli equation, and software modeling
Safety injection tank needs empty for 1500 seconds under 200KPa constant pressures, and during actual test, then about 3500 seconds used times emptying.By
In in actual mechanical process container draining be carried out at the same time with pressurising, pressure can be reduced rapidly with discharge reduction, although holding
Continuous pressurising, pressure also are difficult to stablize in 200KPa, and average pressure is about 120KPa, therefore actual water discharge time (3500 seconds) is relatively managed
By value (1500 seconds) difference, but container can be emptied thoroughly.In short, under 200KPa initial pressures, (4 is small for water discharge time
When) it is significantly faster than gravity drainage (3 days), but container can not be emptied thoroughly；And under 200KPa constant pressures, container water discharge time
(3500 seconds) are shorter, and can thoroughly empty.
