Radiation safety training for the use of nuclear technology is an essential requirement of the regulations, and an important means to ensure the health of radiation practitioners and the safety of radiation environment. After more than ten years of development, the scale of the previous off-line training model basically met the needs of the industry, but some drawbacks also gradually appeared, such as lack of regulatory basis and supervision, high pass rate and poor training effect, increased corporate burden, etc. Since 2020, the National Nuclear Security Administration (NNSA) has officially implemented the reformation of radiation safety training. A unified radiation safety training and assessment platform has been established, covering the training and assessment needs of 11 nuclear technology utilization disciplines, and the training and assessment data are connected with the regulatory platform. The training assessment has changed from “accredited training institutions and paid off-line training and examination” to “free online self-learning and on-site online examination”.

This paper introduced the basic situation of the radiation safety training surveys, carried out multi-dimensional data analyses on the reformation of radiation safety training and assessment, discussed the existing issues in rules and the division of responsibilities between the companies and agencies. Some suggestions, such as adjusting the requirements of rules and regulations, increasing the coverage of nearby assessments, and adding the practical operation assessment, were proposed.
