In conjunction with referring to Fig. 1-Fig. 2, being reality of the utility model embodiment from the underwater radioactivity foreign matter screening arrangement of drainage type
Apply example one.
In the present embodiment from the underwater radioactivity foreign matter screening arrangement of drainage type, including：Tank body 1, end cap 2 and leading truck
3。
The effect of tank body 1 is to install radioactivity foreign matter under water, realizes storage and transhipment to radioactivity foreign matter.Tank body 1
Small volume, be readily transported, effectively prevent accidentally touching equipment in transportational process.In the present embodiment, tank body 1 sets for one end
The hollow accommodating structure for having opening 11a, with accommodating cavity 11.In the present embodiment, the bottom of accommodating cavity 1 is equipped with and tank body 1
Outside be connected the residual water of radioactivity of 1 internal residual of accommodating cavity to be expelled to the drainpipe 12 outside tank body 1.Drainpipe
12 quantity and installation position do not limit, and mainly meeting it can be by the bottom of accommodating cavity 1 equipped with the external phase with tank body 1
Connection.
When it is implemented, tank body 1 by mechanical processing, the methods of weld, pour and make.Specifically, tank body 1 is by coating
The case where having multilayered structure made of the double-layer stainless steel frame enclosing of lead layer, the tank body being likely to occur 1 can be prevented to be corroded.
In the present embodiment, double-layer stainless steel frame is coated on the outside of lead layer, and the thickness of lead layer is greater than or equal to 25mm, no
The thickness of rust steel frame is 5mm.The effect of such setting is：Consider the volume, shielding and versatility etc. of tank body 1
Factor, structure size so, which is arranged, almost can shield all dosage, play to the optimal shield effectiveness of operating personnel.
Such as：Stainless steel frame（It is double-deck）Thickness be 10mm.Steel plate is 24 mm to the plate thickness of γ, can be calculated
Dosage after shielding is 1/2 originally=74.9%, shield effectiveness 25.1%.It installs lead layer additional to be shielded, existing lead layer
The naked lead of the lead content 99.9% of 25mm and 20mm, lead are 13 to the half thickness of γ, and it is original to calculate the shielding post dose that lead layer obtains
1/2 comeThe shield effectiveness of=26.3%, lead layer 25mm are 73.7%；The shield effectiveness of lead layer 20mm is
1/2=34.4%, shield effectiveness 65.6%.
The shield effectiveness of 1 four wall of above-mentioned tank body：The bulk shielding effect of the steel plate of thickness 10mm and the lead layer of thickness 25mm
For 25.1%+73.7%=98.8%.The shield effectiveness of tank body 1 head cover and pedestal：The steel plate of thickness 10mm and thickness 20mm lead layers
Bulk shielding effect is 25.1%+65.6%=90.7%.
Accordingly, it is considered to the factors such as tank body 1 itself dead weight and operating environment, four wall shield effectiveness 98.8%；Head cover and bottom
Shield effectiveness 90.7%, structure size so, which is arranged, almost can shield all dosage, play to the optimal screen of operating personnel
Cover effect.
