Description
Technical field
The utility model relates to technical field of nuclear power, and in particular to the nothing of nuclear power station reaction boron and water make-up system
More specifically the oxygen content change detection technical field of water in oxygen water storage tank is related to a kind of multi-channel fluid pipeline switching
Device.
Background technique
In CPR1000+ unit, nuclear power plant reactor boron and water make-up system include the first anaerobic water storage tank
REA001BA and the second anaerobic water storage tank REA002BA (one of them is used for unit, another is as spare), they are main
It is responsible for supplementing anaerobic water to primary Ioops in nuclear power operational process.It is well known that being during the operation of one loop of nuclear power station normal power
Guarantee that the lower corrosion rate of primary Ioops to the oxygen content in primary Ioops water has strict control.Nuclear safety license file " is changed
And radiochemistry technical specification " provide that the oxygen of the first anaerobic water storage tank REA001BA and the second anaerobic water storage tank REA002BA contains
Amount limit value is 100 μ g/kg of < (in the unqualified situation of the two oxygen content, unit allowed using 24 hours), and needs periodically prison
(specific monitoring mode is to continuously monitor to the oxygen in anaerobic water storage tank currently in use, monitors primary spare nothing daily for survey
Oxygen in oxygen water storage tank).It is general in nuclear power station only to design an online oxygen table REN101MG for save the cost consideration, pass through
As under type realizes the switching to the oxygen content in the first anaerobic water storage tank REA001BA and the second anaerobic water storage tank REA002BA
Monitoring: by the water of the first anaerobic water storage tank REA001BA and the second anaerobic water storage tank REA002BA pass through respectively valve V11 and
V21 is led near online oxygen table REN101MG, and loads onto quick coupling female WV12 and WV22 respectively in end of line, then
The metal hose L32 for being respectively equipped with quick coupling male connector WV31 and WV33 by plugging both ends, connects with quick coupling female WV81
It connects, water is made to flow through online oxygen table REN101MG, realize to the first anaerobic water storage tank REA001BA and the second anaerobic water storage tank
The switching of the oxygen content of REA002BA monitors (referring to Fig. 1).It is not difficult to find that above-mentioned switching monitoring mode be primarily present it is following not
Foot:
1) switching is more troublesome.If the first anaerobic water storage tank REA001BA is used for unit, operate as follows: the first nothing of monitoring
When oxygen water storage tank REA001BA oxygen content, need first to connect quick coupling female WV12 with quick coupling male connector WV31, quickly
Connector male connector WV33 is connect with quick coupling female WV81, then opens valve V11 so that in the first anaerobic water storage tank REA001BA
Water flow through online oxygen table REN101MG, wait after line oxygen table REN101MG registration is stablized, record reading is to realize to first
The monitoring of anaerobic water storage tank REA001BA oxygen content.It is then shut off valve V11, quick coupling female WV22 and quick coupling is public
Head WV31 connection, quick coupling male connector WV33 is connect with quick coupling female WV81, then opens valve V21 so that the second anaerobic
Water in water storage tank REA002BA flows through online oxygen table REN101MG, waits after line oxygen table REN101MG registration is stablized, record
Reading monitors the second anaerobic water storage tank REA002BA oxygen content with realizing；Finally due to the first anaerobic water storage tank REA001BA
It is used for unit, closes V21 after the second anaerobic water storage tank REA002BA oxygen content need to have been recorded, be again coupled to quick coupling mother
Head WV12 and quick coupling male connector WV31, quick coupling male connector WV33 and quick coupling female WV81 open valve V11 with reality
Now the first anaerobic water storage tank REA001BA oxygen content is continued to monitor.Whole process needs repeatedly plug quick coupling female
It is very complicated with quick coupling male connector.
2) there is radiocontamination risk.Handover measurement the first anaerobic water storage tank REA001BA and the second anaerobic water storage tank
REA002BA need to repeatedly plug quick coupling male connector and quick coupling female, be easy to cause metal hose L32 outer wall radioactivity liquid
Body splash with operator (since this metal hose L32 and nuclear power radioactive sample sampling line are located in same vent cabinet,
Therefore its surface has radioactive liquid inevitable), cause radiocontamination.
3) the measurement of oxygen content time is too long.Be already indicated above above in handover measurement the first anaerobic water storage tank REA001BA and
During second anaerobic water storage tank REA002BA, needs to plug quick coupling male connector WV31 and WV33 repeatedly, will cause switching
Oxygen enters to metal hose L32 (after air contact equilibrium, about 8000 μ g/kg of water oxygen level) in air in the process, cuts
Online oxygen table REN101MG registration goes up after the completion of changing, and waits the oxygenated water in metal hoses L32 to be stored up by the first anaerobic water after about 1h
Anaerobic water in tank REA001BA and the second anaerobic water storage tank REA002BA just can accurately show the first anaerobic after being replaced
Oxygen content (nuclear power station " chemistry and radiochemistry technology in water storage tank REA001BA and the second anaerobic water storage tank REA002BA water
Specification " provide that its limit value is 100 μ g/kg of <).It is calculated twice by normal switching daily, which needs about 2 hours.
4) the high false alarm of oxygen content is easily caused, unnecessary communication is increased.Online oxygen table REN101MG measuring signal is transmitted to
Nuclear power master control room is already indicated above after the completion of switching above since oxygen enters to metal hose L32 meeting in air in handoff procedure
Cause online oxygen table REN101MG registration to will rise higher than 100 μ g/kg of alarming value, will cause master control room remote alarms, in order to keep away
Exempt from master control to judge oxygen content by accident, switching front and back is intended to link up with master control in advance every time.
5) potential impact is generated to unit nuclear safety.Oxygen table online is hereinbefore already indicated above after the completion of switching
REN101MG registration goes up, and waits the oxygenated water in metal hoses L32 by the first anaerobic water storage tank REA001BA and second after about 1h
Anaerobic water in anaerobic water storage tank REA002BA just can accurately be shown after being replaced the first anaerobic water storage tank REA001BA and
Oxygen content in second anaerobic water storage tank REA002BA, be equivalent to has 2 hours or so the first anaerobic water storage tank REA001BA daily
Accurate detection is unable to get with the oxygen content in the second anaerobic water storage tank REA002BA.If the first anaerobic water storage tank at this time
The oxygen content of REA001BA and the second anaerobic water storage tank REA002BA go up because of unknown cause more than limit value, pacify to unit core
CR Critical influence is generated entirely.
