Abstract: A low and intermediate level solid radioactive waste disposal repository phase I, stage I project is about to complete all the disposal units of low-level solid waste disposal tasks. In order to ensure that low and intermediate level solid radioactive waste produced by nuclear facilities in the southwest region is timely and properly disposed of, it is very necessary and urgent to carry out the phase I, stage II construction projects. In the design stage of the phase I, stage II construction project, the process plan research is carried out in view of the problems existing in the operation of phase I, stage I, such as the low automation level of the waste receiving inspection equipment, incomplete function, lowl efficiency, low volume utilization rate of the disposal unit, and high radiation risk of personnel. By optimizing the process flow, waste inspection, key equipment parameters, waste placement and control room design, the problems existing in the phase I, stage I are effectively solved. The low and intermediate level solid waste disposal repository is designed into a highly digital and intelligent near-surface radioactive waste disposal repository, which effectively improves the construction of china's radioactive waste disposal capacity.

Key words: low and intermediate level radioactivite solid waste disposal repository, waste inspection, disposal efficiency, waste storage, digitization, intelligent, near-surface
