4D成像和机器人如何为Hanford网站的安全清理贡献

哥伦比亚河每年在食品,水,洪水风险减少,娱乐,栖息地,审美和其他自然资金福利中支撑约1980亿美元。如果我们向您展示了Jacobs如何安全管理世界最大的修复计划之一,旨在保护这一有价值的资源?

As the fourth largest river in North America, covering 258,000 square miles and crossing parts of seven U.S. states and one Canadian province, the Columbia River basin is vital to the Pacific Northwest region’s culture and economy.

On its path back to draining more water to the Pacific Ocean than any other river in North or South America, the Columbia River flows through four mountain ranges, produces drinking water for many communities along its course and irrigates 600,000 acres of farmland.

The river basin in southeastern Washington is also home to the Hanford Site, which for more than 40 years, was home to reactors that produced plutonium for America’s defense program. These weapons production processes left solid and liquid wastes that pose a risk to the local environment, including the Columbia River.

但如果我们向您展示了如何雅各布-在last decade – has managed the environmental cleanup of the Central Plateau at the Hanford Site, using tools such as 4D imaging and robotics to safely perform one of the largest environmental protection programs in the world?

1989年,美国能源部(DOE),美国环境保护局(EPA)和华盛顿州生态部进入了一项法律约束力的协议,Tri-Party协议(TPA),清理Hanford网站。

2008年,DOE聘请了CH2M Hill Plateau Remediation Company(Chprc)作为汉福德中央高原的安全环境清理的主要承包商。Our work on this $6.4 billion-dollar contract includes reducing risks on the Hanford Site by removing some of the DOE’s highest hazard waste streams and facilities, from cleaning up billions of gallons of contaminated groundwater to removing highly-radioactive “sludge” away from the Columbia River.

Chprc的全部范围包括characterization of facilities and waste sites; characterization and retrieval of waste/spent nuclear fuel; environmental protection and regulatory compliance; material handling and processing operations; decontamination and decommissioning (D&D) of nuclear and ancillary facilities; partnership with DOE for establishing milestones according to schedule and funding requirements. Our groundwater cleanup strategy focuses specifically on cleanup along the river, which includes construction, expansion and operation of pump & treat facilities to treat contaminated groundwater and support the overall mission of protecting the Columbia.

From robots...

在近二十年来的第一次,我们现在能够远程探索汉福德网站前核处理设施的潜在危险区域。最近,我们的团队修改了一个小型机器人设备,安全地调查涉嫌氧化氧化(氧化还原)设施的高度放射性污染的区域,是汉福德中部高原的五个前加工设施之一。

机器人配备有仪器来检测放射性和放射污染。附加的相机允许操作员将设备引导到正在调查的区域。该设备确定了一个安全路径,用于进入和退出区域,以帮助通知未来的清理工作。在这里发现更多

......用实时4D成像进入地下

刚刚西部哥伦比亚河海岸线,地下铀浓度仍然在汉福德的300区延续。除了DOE旁边,我们最近将多磷酸盐溶液注入研磨物中,通过称为封存的方法与铀结合,防止铀从地下水到达地下水和哥伦比亚河。该解决方案充当时间释放医学,随着时间的推移分解。当溶液与铀反应时,它产生天然存在的岩石,其稳定在土壤中的铀。

Researchers worked with us to successfully implement a state-of-the-art approach for monitoring the delivery of the polyphosphate remediation using Real-time Four-Dimensional Subsurface Imaging Software (E4D) to take images of the vertical and lateral movement of the polyphosphate solution. E4D uses electrical resistivity tomography (ERT) measurements to reconstruct time-lapse images of the electrical conductivity of the soil. As the polyphosphate solution permeates the soil and the ground’s electrical conductivity increases, an array of ERT sensors continuously measure the change in conductivity. E4D uses the measurements to produce images of the polyphosphate remedy distribution over time.

传感器的测量通过无线互联网立即通过无线互联网传播到康斯坦特,这是一个超级计算机,处理数据,将地质,物理,数学和化学与E4D的建模软件相结合,以在几分钟内创建解决方案的时间流逝3-D图像及其位置。在这里了解更多信息。

持久的遗产

2018年,我们的Chprc团队庆祝收到DOE自愿保护计划(VPP)遗产明星奖,这是一个第一次获得承包商的安全奖VPP Star Statusfor four consecutive years. Members of the team at the T Plant also completed their first shipment of some of the most hazardous material at the site, moving it away from the Columbia River for safe storage.

我们的700多名员工每年捐赠数千小时的时间与当地的小型企业,非营利组织组织进行志愿服务。我们在三城区的存在是我们如何在我们生活和工作的社区中雕刻的真实例子,以及我们的计划对当地社区的影响 - 以及最近宣布其决定延长我们的合同, allowing us to carry on our contributions to the safe cleanup at the Hanford Site and local communities through September 2020.
