RPV irradiation embrittlement data

This article develops a predictive model suitable for describing the irradiation embrittlement of pressure vessels in domestic nuclear power plants based on the collected experimental data of pressure vessel irradiation supervision. The irradiation supervision data used is from the irradiation supervision data of pressurized water reactor nuclear power plants purchased by China National Nuclear Power Operations Co., Ltd. and Nuclear Power Operations Research (Shanghai) Co., Ltd. from the Safety Audit Center, and the data has high reliability. Based on the collected embrittlement data, multiple models were established to fit the data. Different model formulas and formula parameter fitting results were provided in this dataset as the basis for determining the final model.
