Industry, and generate huge economic benefit.
Spallation neutron target general principle is to produce high energy proton using proton precessional magnetometer, heavy metal target is bombarded, by heavy metal
Atomic nucleus smash generation spallation, produce high flux, short pulse neutron, be mapped to sample when neutron beam flows into and come out, by
Spectrometer around target station receives, and scientific research personnel can be by the change of neutron energy and momentum, so as to obtain sample material structure
Information, neutron is because not charged, penetrability is strong and is the preferable probe for studying material microstructure without destructiveness.
During accelerator operation, radiation can be produced, if this radiation leaks goes out that bringing on a disaster property of outside environment can be influenceed.
Protective materials currently used for radiation proof mainly has steel plate, stereotype, water and concrete etc..Wherein lead and steel have compared with
High density, but lead source is few, cost is high, belongs to precious metal, and its denaturation is larger, should not be applied when load is larger；Steel
It is poor that iron is used as workability during radiation proof material；Water has good shield effectiveness to neutron ray, but it is difficult to shape, and is constructing
With it is more complicated in management.Concrete has preferable barrier propterty, and raw material sources are extensive, cheap, application property
Can be good, corresponding shape and size can be made according to structural requirement.Therefore, in radiation proof protective materials, the synthesis of concrete
Techno-economic effect is optimal.It is that Mass Concrete Construction easily produces structural cracks to relate to and put the mortal wound of prevention of mass concrete underground structure
It is raw, so as to cause to seep water and radiation transmission.This is related to both at home and abroad at present and puts prevention of mass concrete underground structure also without comparison system
Construction technology, depend merely on concrete self waterproofing itself and not enough ensure, the current country there is no solution to relate to and put prevention of mass concrete underground structure and prevent
The problem of radiation transmission simultaneously forms set of construction technology, particularly needs to find in water-proofing treatment, radiation proof reliability direction
Solution.
