Radioactive waste is a substance that contains or is contaminated with radionuclides at concentrations or activities that are greater than the clean solution level prescribed by the national regulatory agency and that is expected to be no longer in use. It is mainly derived from processes such as nuclear fuel production, reactor operation, nuclear fuel post-treatment, and nuclear facility retirement, and improper management and disposal of radioactive waste can have adverse effects on human health and the environment now and in the future. The radioactive waste solidification is to convert gas, liquid or solid waste with certain radioactivity into a monolithic solid object with performance indexes meeting the disposal requirements, and the purpose is to form an object which is suitable for loading, unloading, transporting or temporary storage and has the performance meeting the disposal requirements.
The conventional radioactive curing structure mainly comprises the detection of the mechanical property, compressive strength, impact resistance, water resistance, leaching resistance and the like of the radioactive waste curing structure, however, the conventional radioactive waste curing body performance detection utilizes sampling random screening to test the items as a reference standard for judging whether the batch of curing packaging structure meets the requirements, so that some radioactive waste curing bodies cured in the same batch must be damaged in the detection process, or curing bodies with the structure performance which does not reach the standard are missed in the random detection process, thereby causing unnecessary radiation injury to the environment and human beings. In addition, the traditional detection method has long detection time and most items to be detected, and cannot be used for real-time and rapid detection, so that time and labor are consumed in the whole process.

Detailed Description
The invention will now be further described with reference to the accompanying drawings and examples, embodiments of which include, but are not limited to, the following examples.
Referring to fig. 1 to 2, a method for detecting a radioactive waste solidification structure based on XACT (X-ray Induced Acoustic Computed Tomography, X-ray excited acoustic tomography) includes the steps of:
and step 01, manufacturing a plurality of groups of radioactive waste solidified bodies according to different radioactive waste solidification modes. The multi-group radioactive waste solidified bodies with uniform structures are manufactured by different materials such as cement solidification, asphalt solidification, glass solidification and plastic solidification in a traditional mode, the radioactive waste solidified bodies are completely represented, and the radioactive waste solidified bodies are used as standard samples for subsequent acquisition of ultrasonic signals.
Step 02, irradiating the prepared radioactive waste solidified body, namely the standard sample, with suitable pulsed X-rays generated by an X-ray emission device. The wavelength of the X-rays generated by the X-ray emission device is adjusted, so that the radioactive waste solidified body can be collected by the ultrasonic signal collector to obtain an ultrasonic signal with good signal, and the detection accuracy is improved.
And 03, collecting ultrasonic signals converted by the pulsed X-rays produced by the X-ray emission device in the solidified body through an ultrasonic signal collector.
Step 04, the radioactive waste solidified bodies are subjected to performance test by a traditional detection method one by one, ultrasonic signals of the radioactive waste solidified bodies which are qualified in traditional detection are used as ultrasonic signal comparison databases for XACT detection, reliability of manual detection data after standard samples are strictly manufactured is achieved, reliable data are stored to establish databases reaching industry and national standards, accuracy is high, a more accurate and convenient mode is provided for subsequent detection, and meanwhile trouble is reduced for subsequent correction of the databases.
And 05, carrying out XACT detection on the radioactive waste solidification structure to be detected, and collecting ultrasonic signals of the radioactive waste solidification structure to be detected one by one.
And 06, comparing the ultrasonic signals of the detected radioactive waste solidification structure with the ultrasonic signals by using an acoustic wave similarity comparison tool to calculate the similarity of the data of the database. The sound wave similarity comparison tool is an existing software, such as Matlab, spss and other computer tools, calculates the similarity between the sound wave to be detected and the sound wave in the comparison database, and can refer to KTV singing to judge and score.
And step 07, making reasonable logic judgment according to the degree of similarity, namely waiting for further processing as a qualified radioactive waste solidification structure with high similarity, and waiting for further processing as an unqualified radioactive waste solidification structure with low similarity or without a similar signal. The starting similarity may be randomly determined by a value and then the size of this similarity is corrected by a subsequent sample check. For example, when the similarity value is initially higher, random detection finds that many cured structures that are judged to be unacceptable by taking the higher similarity value as a standard are acceptable, and then the similarity needs to be correspondingly reduced. Meanwhile, the similarity for the standard determination may be different depending on the radioactive material of the cured structure.
The ultrasonic signals of the radioactive waste curing structure to be detected are detected and collected through XACT, and compared with the data of the database, whether the radioactive waste curing structure to be detected is qualified or not can be rapidly judged, so that the radiation hazard caused by damaging a part of radioactive waste curing bodies in each detection is changed, and the problem that unqualified curing bodies are missed due to random spot check in the traditional detection mode is avoided.

And the data supplement obtained by the test is fed into the database, and the database is continuously enriched, corrected and perfected, so that the accuracy of the data of the database is continuously improved. Over time, the detection method of damaging the solidified body of the waste in the conventional detection is completely replaced.
Step 09, the radioactive waste solidification structure determined to be unqualified in step 07 and step 08 is crushed and re-manufactured into a new radioactive waste solidification structure to be detected, and the detection is carried out again in step 05, and the radioactive waste solidification structure determined to be qualified in step 07 and step 08 is subjected to waste storage, so that the accuracy of XACT detection is further improved.
