The nuclear criticality safety issue in spent fuel reprocessing facilities is closely related to the main process and is almost equally important. It is closely related to the design and operation of reprocessing facilities. The requirement of nuclear criticality safety greatly restricts the operational capacity of the spent fuel reprocessing process, thereby affecting the economic efficiency of reprocessing. In the post-processing process, both multiphase uranium-plutonium mixed systems and multi body interaction systems are involved. The system characteristics are complex, and experimental simulation is difficult, which greatly restricts the further improvement of the production and operation capabilities of the pilot plant. However, due to the criticality safety challenges caused by reactivity changes such as the non-uniformity, dynamic complexity, and instability of the solution in the reactor under boiling nitric acid during the dissolution process, it has become a key research topic in various countries. According to the criticality safety problem of nuclear fuel dissolution process, the criticality effect of nitric acid concentration was studied. The criticality experiment data of nuclear fuel dissolution process were obtained by keeping the concentration of nitric acid in the same fuel concentration. Four experiments were conducted with different concentrations of nitric acid. During the experiment, the subcritical extrapolation method, reactivity interpolation method, and stable power method were used to complete the criticality experiment. The experimental results show that with the increase of nitric acid concentration, the relative deviation of the criticality experiment data is 0.068%, and the relative deviation between the criticality experiment results and the theoretical calculated values is 0.39%. The research results show that the reactivity of the system gradually increases as the concentration of nitric acid decreases. Therefore, it is necessary to consider the reactivity changes caused by changes in the criticality safety of the spent fuel dissolution process, and high attention is needed. According to the agreement between the experiment and the theoretical calculation, it is appropriate to use the Monte Carlo code MONK to calculate and analyze the acidity effect of the solid-liquid two-phase solution system, which can be used as a nuclear criticality safety control engineering design process for the solid-liquid two-phase nuclear fuel dissolution system. This series of experiment data can be used for calculation, verification, and safety evaluation of critical analysis under solid-liquid coexistence conditions of nuclear fuel. This paper results provide data support for improving the criticality safety control level of critical post-processing equipment. [ABSTRACT FROM AUTHOR]

Immunotherapy, as the fourth largest anti-tumor treatment method, has made breakthrough progress in the field of cancer treatment. Checkpoint inhibitors have been widely used in the treatment of various malignant tumors, and a lot of clinical evidence and experience have also been accumulated in the field of gynecological malignant tumors. However, there is still a lack of standardization in the application of immunotherapy such as immune checkpoint inhibitors for the treatment of gynecological malignant tumors. Therefore, led by the Cancer Endocrine Professional Committee of the China Anti-Cancer Association, experts from multiple fields were organized to use high-quality clinical research results as well as the results of the 2023 American Society of Clinical Oncology (ASCO) conference as evidence. Through discussion and voting, the consensus of Chinese experts on immunotherapy for gynecological malignant tumors (2023 version) has been formed. This consensus recommended the clinical application of immune checkpoint inhibitors for the classification of common gynecological cervical cancer, endometrial cancer, ovarian cancer and other malignant tumors, such as single drug or combination chemotherapy, targeted therapy, etc. It summarized the research and application of tumor vaccines, adoptive cell immunotherapy and cytokine immunotherapy in gynecological malignant tumors, and provided reference for domestic peers, in order to further standardize the clinical practice of immunotherapy for gynecological malignant tumors.
