Description
Technical field is used as nuclear reaction the present invention relates to a kind of novel pipeline that can be taken precautions against leakage and block
Heap the primary Ioops particularly primary Ioops of liquid metal nuclear reactor and the pipeline of intermediate loop, it can also be used to as the various liquid of conveying
The pipeline of other poisonous and harmful substances such as gaseous state industrial chemicals.
Technical background will cause Radioactive Pollution to pollute ring it is well known that nuclear reactor primary Ioops once leak
Border, reactor may be caused to lose the serious accident of cooling agent if primary Ioops badly broken fails to be found in time；Particularly
For liquid metal nuclear reactor, Radioactive Pollution can occur for not only primary Ioops leakage, and because primary Ioops are with
Between loop pipeline wall cooling effect, when metal liquid flow velocity is slower in the loop, the cooling effect of pipeline wall is possible to
The metal liquid temperature in pipeline is set to be reduced to below fusing point so that solidifying, so as to cause line clogging accident；In addition, for defeated
Send the pipeline of other poisonous and harmful substances such as various liquid gaseous state industrial chemicals once damaged, it is also possible to cause serious environmental pollution
Accident.
The content of the invention is it is an object of the invention to provide a kind of novel pipeline that can be taken precautions against leakage and block, and it is except tool
Playing the role of conventional pipeline can convey outside liquid gaseous material, also have the characteristics that.1st, when for nuclear reactor primary Ioops,
Once leakage, which occurs, can send alarm signal in time and harmful substance is enclosed in limited confined space；2nd, available for liquid
The primary Ioops of metal nuclear reactor and intermediate loop and the material higher for conveying other fusing points, are prevented because of pipeline wall
Cooling effect causes the mass sets of conveying in pipeline and pipeline blocking accident occurs；3rd, can also be used for conveying various liquid gaseous states
Other poisonous and harmful substances such as work raw material.
In addition to including service pipe, it also includes a kind of leakage and novel pipeline blocked of can taking precautions against of the present invention
Protection pipeline outside service pipe, the left sealing support for being used in protection pipeline fixing service pipe and right sealing support, enter
Tracheae, blast pipe, pressure measuring piece；Left sealing support and right sealing support are respectively positioned at the left and right ends of protection pipeline, with instrumentation tubes
Road, protection pipeline together, will protect the space between pipeline and service pipe to become a confined space, can by air inlet pipe and
Blast pipe by inert gas be filled with the confined space and make inert gas in the confined space pressure be maintained at one setting

Other problemses, need not repeat herein.(4) when the pipeline is used for liquid metal nuclear reactor, it is pumped into the inertia of confined space 11
Gas should be provided by external inert gas electric heating system to keep constant temperature, the power source of external inert gas electric heating system
Should be two or more, in addition to it may be from this liquid metal nuclear reactor itself electricity power, should also come from includes backup diesel
Other power sources such as machine generating set, power network or another nuclear reactor, to ensure to stop in this liquid metal nuclear reactor
During heap, the material in service pipe 4 remains to be maintained at more than fusing point as needed.For nuclear submarine power, electric heating system
Power source should include this liquid metal nuclear reactor, auxiliary diesel engine generating set and the small-sized Natural Circulation pressure of another seat
Water-water reactor.(5) for liquid metal nuclear reactor, liquid metal nuclear reactor, intermediate loop heat exchanger, steam generator
Before being both needed to install electric heating system to be restarted again after reactor shutdown, coolant metal everywhere is set to be in advance
Liquid.After employing the present invention, the primary Ioops of liquid metal nuclear reactor can be used fusing point higher but security also higher lead
To ensure security, still can then be dropped as intermediate loop using the relatively low lead bismuth alloy of fusing point when reactor restarts
The temperature of heating needed for low steam generator, ensure the coolant metal in the intermediate loop in steam generator in reactor weight
Liquid is at during new startup.(6) (three) described herein, (four), (five) although 3 contents with the present invention set and one kind
Leakage and the novel pipeline blocked can be taken precautions against is practiced without direct relation, but with its most important implementation environment liquid metal
Nuclear reactor is relevant, therefore is illustrated in this together.The primary Ioops of liquid metal nuclear reactor and intermediate loop can be by multistages
