按照世界核协会预测,2025年之后,全球对天然铀需求将保持较快增长,但天然铀产量却无法保持同步增长,从而导致缺口出现。按照我国核电建设规划来看,2030年将达到1.5亿~2.0亿kW,每年大约需要2.2万t天然铀。如何在做好国内铀矿勘查,提高天... 按照世界核协会预测,2025年之后,全球对天然铀需求将保持较快增长,但天然铀产量却无法保持同步增长,从而导致缺口出现。按照我国核电建设规划来看,2030年将达到1.5亿~2.0亿kW,每年大约需要2.2万t天然铀。如何在做好国内铀矿勘查,提高天然铀产能的同时,加快海外国家尤其是"一带一路"沿线国家的铀资源开发力度,实现"两个市场,两种资源"并举,对保证我国核电发展和实现核工业"走出去"战略都具有重要意义。在对"一带一路"国家铀资源分布状况和开发条件研究基础上,提出了开展海外铀资源开发工作建议。 展开更多

Due to recent legislative incentives and a general change in the public eye towards environmental and energy issues, a renewed interest in building nuclear power plants has taken place in the U.S. The Nuclear Regulatory Commission has also recently given approvals to build four nuclear reactors in two southeast states, which further indicates the resurging interest in nuclear power in the U.S. Such approvals, however, do not specifically address the impact on having a constrained labor force when manufacturing and constructing multiple reactors. Key findings include the comparison of a constrained and unconstrained workforce on construction and manufacturing completion times, the identification of peak labor requirements based on different construction schedules, and the development of training estimates to ensure the workforce and industry are prepared for the new jobs being created. Results suggest that a shorter planned construction timeline is effective when the workforce is moderately constrained to unconstrained. However, with a severely-constrained starting workforce, a longer construction timeline is preferred. For multiple reactor plans, spreading out the construction start dates outperforms all other construction start date schedules. In particular, heavily compressed start dates could effectively kill a resurgent nuclear industry, especially if workforce expansion is not pursued simultaneously. 展开更多
