高放核废物的地中处置(HLW)与CO2的捕集与封存(CCS)在环境问题方面有一定的相似性。文章从物理性质、封存机理、环境影响角度,就CO2和HLW地质处置的环境问题进行对比研究,旨在为CCS的环境风险管理提供思路。通过对比分析得出,泄漏的CO2... 高放核废物的地中处置(HLW)与CO2的捕集与封存(CCS)在环境问题方面有一定的相似性。文章从物理性质、封存机理、环境影响角度,就CO2和HLW地质处置的环境问题进行对比研究,旨在为CCS的环境风险管理提供思路。通过对比分析得出,泄漏的CO2在地层和空气中的扩散能力较强,对人体健康、水体质量等都有一定的影响,但危害程度比较浅,持续时间也比较短;而泄漏哪怕极少的核素,其放射性和毒性都会对人体健康和环境安全造成很严重的威胁。因此,同样剂量泄漏的背景下,CO2的环境影响没有HLW的环境影响严重,CO2地质封存可以从核废物地中处置的环境管理中借鉴经验。 展开更多

USA nuclear waste management program has stalled due to its continued insistence upon using Yucca Mountain for its disposal of DOE (Department of Energy) and commercial power plants NSF (nuclear spent fuel). Increased flexibility and significant changes in DOE program are proposed. They include a private waste company to manage it; the construction and operation of ICS (interim centralized storage) facilities for NSF; the search for an AGR (alternate geological repository); the use of a different methodology involving key local and state participants; a new "as safe as practical" strategy with defined benefits to the involved locations and states. Assured removal of NSF from ICS and providing limited Price Anderson indemnity for the program will enhance its acceptance. Minimum politics, regular information meetings, compromises, good cost projections and meeting schedules will be necessary to increase the chances of the proposed nuclear waste management program. 展开更多
