Study On Comparison Of Domestic And Foreign Reservoir Retirement Standard And Method Of Reservoir Retirement Assessment

This paper, in Shaanxi province’s existing medium-sized and small-sized reservoirs decommissioning project as objects, to carry out intensive investigations, grasp the security status of the province decommissioning reservoir; Collection of multiple domestic and foreign standard text reservoirs retirement, and comparative analysis of the domestic and foreign standards decommissioned reservoir similarities and differences, identify the problems of our reservoir retirement standards, proposed amendments to our reservoir retirement standards; Establish a hierarchical analysis model of decommissioning reservoir evaluation, the reservoir in Yulin shanxi province for decommissioning by the proposed method were evaluated, and achieved good results. Papers obtained results are as follows:(1) Domestic and foreign reservoir retirement standards are highly consistent in the aspects of safety, economy and environment. But there are many differences, mainly reflected in the following aspects: in the development of foundation and starting point; decommissioning program; qualification requirements for evaluators; division of the assessment phase of the process; data collection; assessment mode; involving the department; removal of dam costs; determination of engineering design standard; basis of the evaluation; operability.(2) By comparing the domestic and foreign reservoir retirement standard, carefully analysis of our country reservoir retirement standard and that our country reservoir retirement standard deficiencies is mainly reflected in the following aspects: the starting point is limited to the cost and benefit; the decommissioning program unreasonable; reservoir retirement data collection is not clear; assessment evaluation model is not reasonable; reservoir decommissioning costs sources rely heavily on in government funding; the reservoir retirement assessment practitioners qualification is not required; poor operation; reservoir retirement standard of small reservoirs attention degree is low; reservoir retirement ecological environmental impact assessment is not perfect; reservoir retirement propaganda is not enough.(3) Through comparing the reservoir retirement standards, combined with China’s actual situation, we put forward to our country reservoir retirement standard amendments, it should be improved in the following aspects: change the starting point; improving reservoir retirement assessment procedures; clear reservoir retirement data to be collected; give full consideration to all stakeholders, involving them in the assessment of reservoir retirement work; improving reservoir retirement assessment style; strict qualification requirements reservoir retirement evaluators, with the qualification certificate for employment; improve fund-raising scheme; the introduction of the relevant technical standards; a reasonable choice of decommissioning; do typical reservoir retirement cases to provide a reference; to strengthen monitoring and surveillance; strengthen the management of the reservoir after retirement; do propaganda work.(4) Proposed reservoir retirement evaluation AHP.(5) The assessment of the proposed method for the retirement of the reservoir in the Yulin area of Shaanxi was carried out, and the results proved that the evaluation system was more practical.
