Activation sheet irradiation capsule is the box-like device for placing activation sheet, and in high-temperature reactor heap after high flux neutron irradiation, require that activation sheet irradiation capsule can pick and place arbitrarily, induced radioactivity is little, and security is high.
In the prior art at present, the reactor temperature making moderator/cooling medium with water or heavy water is lower, and its activation sheet irradiation capsule adopts the organic materials such as tygon to be prepared from.And it is very high to do the reactor temperature of cooling medium with high temperature helium, liquid metal sodium, liquid metal lead or high-temperature liquid state fused salt, the activation sheet irradiation capsule that traditional organic material is made cannot continue to use in above-mentioned high-temperature reactor.
utility model content:
Technical problem to be solved in the utility model is: provide a kind of easy processing, neutron-absorption cross-section is little, chemical stability good, the activation sheet irradiation capsule for high-temperature reactor of dimensionally stable under high temperature.
The technical scheme that the utility model is taked for technical solution problem is:
A kind of activation sheet irradiation capsule for high-temperature reactor, comprise activation sheet, described activation sheet irradiation capsule is by being interconnected and providing the lid of enclose inside cavity and box body to form, be provided with described activation sheet in described internal cavities, described lid is connected by buckle with between box body or is threaded connection; Described activation sheet irradiation capsule is prepared from by high temperature resistant carbon/carbon composite.
Described activation sheet irradiation capsule is spherical structure, and described lid and box body are semicircular structure, and described lid is connected by buckle with between box body or is threaded connection and provides enclose inside circular cavity; The inwall center of described lid and box body is provided with the draw-in groove matched each other up and down, and described activation sheet is arranged in described draw-in groove.
Described activation sheet irradiation capsule is capsule shape structure, and described lid and box body are " U " shape structure, and described lid is connected by buckle with between box body or is threaded connection and provides enclose inside capsule cavities; Described closed capsule shape cavity inner wall center circumference is extended the draw-in groove matched each other up and down, is provided with fixed support ring, is provided with described activation sheet in described fixed support ring in described draw-in groove.
One or more described activation sheet is provided with in described fixed support ring.
Activation sheet irradiation capsule provided by the utility model is spherical or capsule shape structure, for in the measuring system engineering of high-temperature reactor, there is low, the easy processing of cost, high temperature resistant, neutron-absorption cross-section is little, density of material is low, mechanical property is good, the advantage such as dimensionally stable under chemical stability, high temperature, can use in high-temperature reactor, can pick and place arbitrarily, induced radioactivity is little, and security performance is higher, is applicable to the application that high-temperature nuclear reactor neutron-flux density is measured completely.
Activation sheet irradiation capsule provided by the utility model is processed by carbon/carbon composite.The neutron-absorption cross-section of carbon/carbon composite is 3.5 × 10
-27cm
2, can not radioactivity be produced after neutron irradiation; Carbon/carbon composite density is little, is enough to pass through gas push.In an inert atmosphere, the mechanical property of carbon/carbon composite increases with the raising of probe temperature (to 2200 DEG C).Carbon/carbon composite also has good structure designability, can carry out concrete shape design according to the stressing conditions of parts and request for utilization.Therefore carbon/carbon composite is particularly suitable for the activation sheet irradiation capsule of high-temperature reactor.
