Practical Solutions To Difficult Decommissioning Issues - Lessons Learned

摘要

Over the past several years the Nuclear Regulatory Commission (NRC) has evaluated its decommissioning regulations and processes, and as a result, has implemented a number of changes to its decommissioning program and its approach to reviewing regulatory decommissioning issues. This paper discusses seven of the innovative approaches usedrnby both licensees and the NRC staff to resolve difficult decommissioning issues, such that they may be used by otherrnlicensees and staff in the future. Based on these and other experiences, the NRC has identified a number of generic lessonsrnlearned from the NRC perspective, four of which will be discussed in the paper. To document these lessons learned, wernare establishing a revised web page for decommissioning. The revised web page will include information on therncomprehensive decommissioning program and have a special section for lessons learned. The lessons learned page willrninclude information that will benefit the NRC staff, current decommissioning licensees, future decommissioning licensees,rnand future reactors. The paper will also discuss what can be done in the design and planning phase of future facilities thatrnwill make eventual decommissioning more efficient and effective. In summary, the industry and staff have implementedrninnovative approaches to decommissioning and have learned a number of lessons from the sites that are currently inrndecommissioning. The staff will document these innovative approaches and lessons learned in our guidance and look atrnactivities and designs such that the decommissioning sites of tomorrow can take advantage of issues that were resolved byrnthe decommissioning sites of today.
