Obtain cold section of temperature of the primary Ioops coolant.
Wherein, the system also includes the 4th measuring device, the 4th measuring device is cold for measuring the primary Ioops
But the temperature at the hot arc temperature point of agent, the hot arc temperature point are set to steam generator top cylinder and steam generation
On upper chamber's annular channel between device spiral heat-transfer pipe component.
Specifically, first measuring device includes:
First pressure inlet is fixed on the outer wall of steam generator lower cylinder, and is located at the lower chambers annular channel
On；
First sensor for measuring temperature is located in first pressure inlet, for measuring the cold of the primary Ioops coolant
Temperature at section changeover portion measuring point.
More specifically, first pressure inlet includes:
One end of first thermometric protection adapter tube, the first thermometric protection adapter tube is closed end, and other end is open end,
The inside of first thermometric protection adapter tube, which is formed, stirs and make muddy pipe, and the open end of the first thermometric protection adapter tube is fixed on the steam hair
On the outer wall of the lower cylinder of raw device, offered on the tube wall on first thermometric protection adapter tube coolant inflow direction more
A coolant inflow hole offers coolant outflow on the tube wall on first thermometric protection adapter tube coolant outflow direction
Hole.
First sensor for measuring temperature is the fast-response thermal resistance thermometer with casing.
In order to enable the temperature of measurement is uniform as far as possible, the probe of the first sensor for measuring temperature should be made to be set to cooling
Agent is flowed out on direction.
Due to hygrosensor measurement coolant temperature when, what ideal insertion depth should be runner caliber 1/2 arrives
1/3, thus in order to enable the sensor for measuring temperature in pressure inlet can be measured positioned at the cold of 1/2 to 1/3 place of runner caliber
But the temperature of agent, thus pressure inlet answers insertion depth between runner 1/2 to 1/3.
By designing adapter tube mouth structure, on the outer wall for the cylinder that the open end that will take over mouth is fixed on lower part, and will take over
Mouth is inserted on annular channel, is set up multiple openings in the side that the coolant of protection adapter tube flows into, is introduced coolant into first
It is stired and make muddy in thermometric protection adapter tube, and sensor for measuring temperature is arranged in the direction of coolant flow outlet, thus realization pair
The temperature of cold section of changeover portion measuring point of coolant measures.
Wherein, the second pressure inlet and the first pressure inlet structure having the same, thus no longer describe herein.
Above-mentioned measurement method is illustrated referring to the citing of Fig. 3~7.
As shown in figure 3, primary Ioops coolant hot arc temperature point is arranged in steam generator top cylinder 11 and steam
On upper chamber's annular channel 13 between generator spiral heat-transfer pipe component 12, if its temperature measured is THeat；
Cold section of changeover portion point layout is in steam generator lower cylinder 21 and steam generator spiral heat-transfer pipe component 12
Between lower chambers annular channel 23 on, if its temperature for measuring is Δ TIt is cold；
After coolant enters once through steam generator, by temperature flow field Thermal Analysis, find in once through steam generator
The position in upper chamber's annular channel section 90 and 270 between top cylinder 11 and steam generator spiral heat-transfer pipe component 12 is cold
But the hot arc temperature of agent is stired and make muddy relatively uniform, and temperature flow field is more stable, therefore the hot arc hygrosensor of coolant is arranged
On the two positions, specifically as shown in figure 4,0 degree of position in the annular channel section is located at the entrance of coolant.Extremely
In height of institute's cloth measuring point apart from once through steam generator inlet and outlet section, by coolant temperature in actual DC steam generator
The Thermal Analysis in flow field is determined.
Since once through steam generator barrel wall is too thick, thermal resistance thermometer insertion depth is insufficient, thus uses pipeline temperature
Degree measurement pressure inlet.As shown in figure 5, the pressure inlet is fixed on the cylinder body outer wall 31 of steam generator, which includes:
One thermometric protects adapter tube 34, and it is tubular structure closed at one end which, which protects adapter tube 34, and the first thermometric protection connects
The open end of pipe 34 is fixed on cylinder body outer wall 31, the tube wall on first thermometric protection 34 coolant inflow direction of adapter tube
On offer multiple coolant inflow holes, including the first coolant entrance 36, the second coolant entrance 37, third coolant entrance
38, by the way that coolant flow inlet is arranged, stiring and make muddy in space for thermometric protection adapter tube is introduced coolant into, to realize different level
Coolant stir and make muddy.Coolant flow is offered on the tube wall on first thermometric protection 34 coolant of adapter tube outflow direction
Portal 32.The inner wall of first thermometric protection adapter tube 34 stirs and make muddy pipe 35 to be isodiametric, and outer wall is straight from closed end to open end
Diameter tends to increase.Hygrosensor 33 is fixed on the cylinder body outer wall of steam generator, and is located at and is stired and make muddy in pipe 35.Wherein,
Dotted line 39 is located at steam generator chamber annular channel central axes.
By this structure on chamber annular channel, making the 1/2~1/3 of pressure inlet insertion depth runner caliber, then
Chamber annular channel different level opens three coolant inlet openings, and the coolant of different level is stired and make muddy in pipe 35 in coolant to be mixed
It is flowed out afterwards from coolant apopore, position of 33 insertion depth of hygrosensor at apopore.Thermal resistance detector institute in this way
The temperature of survey is the temperature after coolant is stired and make muddy, and the temperature equalization surveyed and representative can also by using pressure inlet design
Prevent impact of the coolant fluid to thermometer.
According to the runner schematic diagram of coolant, as shown in fig. 6, cooling can be neglected because there is insulating layer on short sleeve
Agent is in the loss through short sleeve heat, between 41 top cylinder of steam generator and steam generator spiral heat-transfer pipe component
Upper chamber's annular channel on the hot arc temperature surveyed, the hot arc temperature T of the primary Ioops coolant of as small-sized heapHeat；
Because primary Ioops coolant is through steam generator 41, right side short sleeve 44,42 top ring cavity of pressure vessel, left side is short
Casing 45 is returned in pressure vessel 42 again after main pump 43, and in this process, the coolant come out through steam generator 41 is wanted
It is heated in the ring cavity of pressure vessel 42 and the temperature of coolant is caused to increase, if the temperature of its variation is Δ TRing, flowing through master
After pump 43,43 bearing of main pump can heat coolant, and increasing its heat, (large pressurized water reactor reactor coolant can also flow through main pump
Heating), if its increased temperature is Δ TMain pump, have insulating layer in cold section of other parts of coolant, therefore ignore the temperature of other sections
The variation of degree can be with by the comparison of runner figure Fig. 7 of runner figure Fig. 6 and large pressurized water reactor coolant of small-sized reactor coolant
It was found that pressure vessel ring cavity at cold section of temperature runner of small-sized heap more one, thus to remove temperature caused by flowing through ring cavity heating
Difference, cold section of temperature T of the primary Ioops coolant of that the one small-sized heapIt is cold=Δ TIt is cold-ΔTRing+ΔTMain pump。
The above disclosure is only the preferred embodiments of the present invention, cannot limit the right model of the present invention with this certainly
It encloses, therefore equivalent changes made in accordance with the claims of the present invention, is still within the scope of the present invention.
