摘要

目的:选择和证明在评估计划活动实施对人员和公众的潜在危害时必要和充分的健康物理学标准,这可能导致核燃料循环(NFC)企业辐射状况恶化。结果:为了及时评估NFC企业计划开展活动的可行性,制定了一种方法,用于评估辐射情况可能恶化时的辐射安全和防护。结论:每一个可能导致NFC企业辐射状况恶化的计划事件都不应导致辐射状况的重大变化,也不应超过既定的健康物理标准:•不超过主要剂量限制;•不增加NFC企业的潜在辐射危害类别;•不增加使用未密封辐射源的工作类别;•根据工作条件特别评估的结果,允许增加人员的工作条件等级。在对辐射技术竞争力进行比较评估时,应预先评估辐射状况的潜在变化和实施补偿措施的成本,以在引进新技术后辐射状况恶化的情况下保护人员和公众。

Health Physics Criteria for Assessing the Radiation Situation with Changing Technology at a Nuclear Fuel Cycle Enterprise
Purpose: To select and justify health physics criteria necessary and sufficient in assessing the potential hazard for the personnel and public from the implementation of the planned activity, which can lead to deterioration in the radiation situation at the nuclear fuel cycle (NFC) enterprise. Results: To promptly assess the feasibility of carrying out an event planned at the NFC enterprise, a methodology has been developed for assessing radiation safety and protection in case of potential deterioration in the radiation situation. Conclusion: Each planned event that may lead to deterioration in the radiation situation at a NFC enterprise should result in neither significant changes in the radiation situation nor exceeding the established health physics criteria: • non-exceeding main dose constraints; • non-increasing the category of potential radiation hazard of the NFC enterprise; • non-increasing the class of work with unsealed radiation sources; • permissible increase in the class of working conditions of the personnel based on the findings of special assessment of working conditions. In a comparative assessment of the competitiveness of radiation technologies, potential change in the radiation situation and the cost of implementing compensatory measures should be pre-evaluated to protect the personnel and public in case of deterioration in the radiation situation following the introduction of new technologies.
