核岛安装作为核电站工程建设中的重要一环,肩负着反应堆一回路主设备安装、核岛内管道安装以及相关程序审查等重要任务。然而,随着核岛安装施工管理由单项目管理向多项目管理的转变,核岛安装专业管理、技术人员匮乏的问题越来越突出,并成为制约核岛安装工作成功的关键因素之一。本文通过对单项目、单基地核岛安装管理模式的分析,结合当前核电建设多项目、多基地同时开展的实际形势,立足核岛安装管理的实践经验,提出了一整套核岛安装新型管理模式。 相似文献

在核电站建造过程中,房间移交是土建或安装、调试在核电建造过程中间的一个物理空间分界点和管理责任转移点;土建工作完成到一定程度后将房间移交给安装单位施工并管理,安装完成工作后将房间返交土建进行后续作业,其中还会穿插重返工作区、临时介入施工过程,房间管理责任也随作业性质而改变,在某种程度上,房间的顺利移交与否,将直接影响整个项目施工能否按计划执行。 相似文献

Pandit Jawaharlal Nehru and Dr. Homi J. Bhabha, the visionary architects of Science and Technology of modern India foresaw the imperative need to establish a firm base for indigenous research and development in the field of nuclear electricity generation. The initial phase has primarily focused on the technology development in a systematic and structured manner, which has resulted in establishment of strong engineering, manufacturing and construction base.The nuclear power program started with the setting up of two units of boiling light water type reactors in 1969 for speedy establishment of nuclear technology, safety culture, and development of operation and maintenance manpower. The main aim at that stage was to demonstrate (to ourselves, and indeed to the rest of the world) that India, inspite of being a developing country, with limited industrial infrastructure and low capacity power grids, could successfully assimilate the high technology involved in the safe and economical operation of nuclear power reactors. The selection of a BWR was in contrast to the pressurized heavy water reactors (PHWR), which was identified as the flagship for the first stage of India's nuclear power program. The long-term program in three stages utilizes large reserves of thorium in the monazite sands of Kerala beaches in the third stage with first stage comprising of series of PHWR type plants with a base of 10,000 MW. India has at present 14 reactors in operation 12 of these being of PHWR type.The performance of operating units of 2720 MW has improved significantly with an overall capacity factor of about 90% in recent times.The construction work on eight reactor units with installed capacity of 3960 MW (two PHWRs of 540 MW each, four PHWRs of 220 MW each and two VVERs of 1000 MW each) is proceeding on a rapid pace with project schedules of less than 5 years from first pour of concrete. This is being achieved through advanced construction technology and management. Present efforts are focused on further reduction of gestation period. This is in contrast to construction period of 7–14 years in the earlier projects with labour intensive construction methods, learning period and indigenisation. The schedule and cost are interrelated and ultimately determine the viability and competitive edge of a project. With rich experience of over 30 years of operation and construction management it is well established that setting up of nuclear power projects in India in 4–5 years is quite feasible because of tremendous developments in construction technology; mechanization, parallel civil works and equipment erection, computerized project monitoring and accounting systems. By considering the best achieved times for the critical path activities of previous and ongoing projects, even a 4-year schedule is achievable. For nuclear power to be competitive it is essential that the gestation period is reduced and the capacity utilization enhanced. Both of these are the goals of the Indian nuclear power program. Presently the overnight cost per kW installed capacity is in the range of US$ 1100–1300 with levellised tariff of 5 c/kWh. 相似文献

Space power is one of the core technologies for space exploration. Space nuclear reactor power is characterized by high energy density, wide power coverage and small dependence on space environment, which is a promising choice for future space power. In this paper, the existing space power systems in view of mission targets and system specific mass were compared, potential application of space nuclear reactor power in future space activities was presented. Based on the investigation of the future civil and military space missions, the power requirement of space nuclear reactor power was summarized. According to different powers, the various technology schemes for space nuclear reactor power in the open literatures were compared, and the relatively optimized technical roadmaps for different power levels were given. This study can provide guidance for the space nuclear reactor power system design. 相似文献
