Description
Technical field
The utility model, which belongs to, relates to nuclear site equipment technical field, and in particular to a kind of spent fuel transport container decontamination operation
Platform.
Background technique
Nuclear Power Station's Exhausted Fuels transport/hold-up vessel be for the transport of reactor spentnuclear fuel and dry storage container it is (following
Abbreviation shipping container), shipping container is filled after spentnuclear fuel before transport/storage, and it is dry that draining need to be carried out to spent fuel transport container
It is dry, rush helium leak test, dress outer cover and container outer surface decontamination etc. operation.To certain nuclear power stations, in the process, container is out of pond
It is stood upright on after hanging out in reactor building on dedicated decontamination support.Since container reaches as high as 6m, more than 120 tons are weighed, outer surface is stained with
There is radioactive substance, surface contamination is horizontal and radiation level is larger, maximum contamination level about 95Bq/cm2, container outer surface radiation
Be on close level 2mSv/h, needs decontamination solution control to limit value or less that can transport outward；The high about 0.2m of decontamination support coaming plate, is unsatisfactory for cleaning
Condition；And reactor building hangs high limited, shipping container maximum hangs rise and leaves away dirty support less than 1m in the workshop of part.Therefore existing
Some facilities are unsatisfactory for shipping container decontamination operation and require.
By patent retrieval, same category of device has a kind of " spent fuel transport container of China Guangdong Nuclear Power Group Co., Ltd.
Cleaning platform " (Authorization Notice No.: CN201783494U).The equipment is mainly made of principal post, upper platform, lower layer's platform,
