Certification and meet safety standard, therefore, described Quick drainage needs to apply in nuclear power station debugging management system
Interim special facilities (tsd), and put up " tsd label ", just can come into operation.
For the ease of being specifically described to application scheme, below taking safety injection tank as a example:
Corresponding to above-mentioned steps s1, first, by inquiring about nuclear power plant equipment operating maintenance handbook (eomm),
Know that middle pressure safety injection tank highest operating pressure is 4.55mpa, that is, the pressure-bearing scope of this safety injection tank is (0～4.55)
mpa；Then, Theoretical Calculation and incorporation engineering practical experience are carried out based on the modeling of this pressure-bearing scope, really
The safety drain pressure of fixed described container, to guarantee that described container can quickly arrange under this safety drain pressure
Water and will not having an accident, herein, the safety drain pressure being calculated this safety injection tank is 200kpa.Right
In 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 drainings can be adopted
Mode carries out container draining:
1) container carries out draining under the initial pressure of safety drain pressure, that is, step s1 and s2 particularly as follows:
Inflated to described container by aerating pipe, so that the pressure within described container increases, in the process of inflation
Pressure within container described in middle real-time monitoring；Pressure within described container increases to described safety drain
During pressure, isolate this aerating pipe to stop as this container pressurising, so that this container is in this safety drain pressure
Initial pressure under draining；
2) refer to Fig. 3, container draining under the constant pressure of safety drain pressure, that is, step s1 is concrete
Including sub-step: s11, determine the pressure-bearing scope of described container, managed based on the modeling of described pressure-bearing scope
By calculating, to determine the safety drain pressure of described container；S12, filled to described container by aerating pipe
Gas, so that the pressure within described container increases, the pressure within container described in real-time monitoring simultaneously；s13、
Pressure within described container increases to described safety drain pressure, and opens the Quick drainage of described container
When pipeline carries out draining, described aerating pipe is kept to be in open mode, simultaneously in container described in real-time monitoring

So that the pressure within described container maintains described safety drain pressure.
In conjunction with above-mentioned safety injection tank, carry out container draining according to above-mentioned 1st kind of pressurising drainage pattern,
Draining under the initial pressure of 200kpa, about 4 hours used times drained water, in the process, with water by
Gradually discharge, the pressure in container can be gradually reduced, because container bottom is elliposoidal (as shown in Figure 1),
There is back water cannot discharge.Carry out container draining according to above-mentioned 2nd kind of pressurising drainage pattern, in 200kpa
Constant pressure under, by hydraulic formulas such as Bernoulli equations, and software modeling simulate in 200kpa
Under constant pressure, safety injection tank needs emptying in 1500 seconds, and during actual test, then about 3500 seconds used times row
Empty.Because in actual mechanical process, container draining and pressurising are carried out simultaneously, pressure can be fast with discharge reduction
Prompt drop is low although in lasting pressurising, pressure also is difficult to stablize in 200kpa, and average pressure is about 120kpa,
Therefore actual water discharge time (3500 seconds) is compared with theoretical value (1500 seconds) difference, but container can be thorough
Emptying.In a word, under 200kpa initial pressure, water discharge time (4 hours) significantly faster than gravity drainage
(3 days), but container cannot thoroughly empty；And under 200kpa constant pressure, container water discharge time (3500
Second) shorter, and can thoroughly empty.
