Abstract Objective To improve the efficiency of radiation work preparation, promote the comprehensive and whole-process control of radiation risk, strengthen the accumulation of experience feedback data, and improve the timeliness of approval. Methods According to the application of radiation work permits in Tianwan Nuclear Power Plant and other nuclear power plants, the radiation work permit software in Tianwan Nuclear Power Plant was improved in terms of work order connection, examination and approval process integration, approval of radiation work at different levels, unification of level classification standard, radiation risk database establishment and maintenance, and closed loop management and mobile approval of radiation work permit. Results A radiation work permit software for nuclear power plant was developed according to the requirement of radiation risk control. Conclusion The radiation work permit software effectively improves the radiation work regarding work preparation efficiency, risk control, experience feedback data accumulation, and timeliness of approval. Subsequently, information transmission efficiency and experience sharing can be improved through connection and communication with other software in nuclear power plants.
