Description
Technical Field
The invention relates to the technical field of radioactive waste measurement, in particular to a transmission source storage and adjustment device.
Background
Nuclear power plants generate large quantities of low-to-medium level radioactive waste during operation, which, according to national standards, is subjected to a measurement of the radioactivity level before final disposal, a critical step in the measurement being the measurement of the density of the waste drum. The density measurement process needs to use gamma rays emitted by a transmission source for density reconstruction.
Transmission sources are typically stored in shielded containers for worker safety. Typically, when the transmission source is needed, the source is manually turned on and off, and the staff is subjected to relatively large radiation doses during this process. When the trash can density is low, the transmission source energy generally selected is also low, because high-energy rays easily pass through the trash can and are attenuated little, and therefore great errors can be brought to reconstructed density; when the waste drum is very dense, a source of high energy gamma radiation is required to ensure that radiation passes through it. Therefore, at least two transmission sources are generally needed in the actual waste barrel measurement process, and the conventional method is that each source is independently provided with a storage device and is replaced aiming at different barrels.
