RICHLAND, Wash. – Washington State University Tri-Cities continues its partnership with the U.S. Department of Energy to offer the next Hanford lecture focusing on the impact of and preparation for natural phenomena hazards on the Hanford Site at 3:30 p.m. April 18 in the East Auditorium at 黑料社 Tri-Cities.

Students, faculty and the community are welcome to attend the presentation.

Stephen McDuffie, seismic engineer for the Chief of Nuclear Safety at DOE, will speak about how they prepare for natural phenomena such as earthquakes, floods, volcanoes, high winds and mitigation for DOE nuclear facilities and how they determine the requirements for its facilities to withstand those hazards.

Both existing and new nuclear facilities must be designed to withstand natural phenomena to ensure the facilities continue to serve their safety functions during such events.

McDuffie has more than 25 years of nuclear safety experience. He has served as a seismic engineer for the Chief of Nuclear Safety at DOE since September 2008. In this position, he oversees natural phenomena hazard characterization and design activities at DOE facilities and maintains operational awareness at several of DOE鈥檚 high-hazard nuclear facilities. McDuffie holds a bachelor鈥檚 in geology from Whitman College and master鈥檚 and doctoral degrees in earth and planetary sciences from Johns Hopkins University. He also holds a master鈥檚 of business administration degree from 黑料社 Tri-Cities with a focus on decision sciences and revenue management.

The lecture on April 18 will be broadcast live at 黑料社 Pullman, 黑料社 Vancouver, 黑料社 Everett and 黑料社 Spokane via the campus AMS video streaming service.

RICHLAND, Wash. 鈥� Two teams at Washington State University Tri-Cities have partnered with Washington River Protection Solutions to procure and program an autonomous vehicle and develop a form of ultra high-performance concrete to help protect workers in radioactive areas at the Hanford Site and safely immobilize solid secondary wastes.

WRPS is the U.S. Department of Energy鈥檚 Tank Operations contractor responsible for managing Hanford鈥檚 56 million gallons of highly radioactive waste and preparing it for delivery to the Waste Treatment Plant on the site. The partnership for the projects will provide WRPS with customized technology to fit their needs, in addition to further improving the safety capabilities of its employees and environmental impact stemming from the tank farms at the Hanford Site.

Robotics to analyze radioactive vapors

WRPS provided a 黑料社 team with an initial contract to procure and program an autonomous vehicle that would be used for measuring vapors, or chemical gases, within the tank farms.

The 黑料社 team consists of Akram Hossain, vice chancellor for research, graduate studies and external programs; Scott Hudson, professor of electrical engineering; John Miller, associate professor of computer science; and Changki Mo, associate professor of mechanical engineering.

The team plans to purchase a pre-fabricated, compact and programmable vehicle, which has the capacity to hold 40-50 pounds of equipment. The team will then eventually outfit, customize and program the vehicle for its desired purpose within the tank farms. The vehicle must be able to follow a defined path, dock itself to charge its battery, withstand long-term use, be able to run autonomously, as well as allow manual override operations.

鈥淭his vehicle will be going into areas, minimizing personnel entries, so we need to assure that it can operate reliably and it won鈥檛 break down,鈥� Miller said 鈥淲e have to make certain that the quality is of impeccable standards and that the system can demonstrate operational longevity in these areas.鈥�

The design of the autonomous vehicle marks the first phase of what will potentially turn into a multi-phase project. WRPS has also expressed interest in having the robot detect obstacles in a changing environment, change filters at the site and monitor radiation. Miller said those challenges will most-likely be addressed in future phases of the project.

鈥淭his is a great opportunity, both for 黑料社, as well as for our students,鈥� Miller said. 鈥淚t creates opportunities for undergraduate research, as well as providing funding for graduate research. It is the perfect opportunity for us.鈥�

The team plans to have the first phase of the autonomous vehicle completed and demonstrated to WRPS in the next few months. The team will conduct demonstrations and additional phases of development over the course of the year. When fully developed, the autonomous vehicle would be deployed in tank farms to support construction and operations.

Ultra high-performance concrete to encapsulate nuclear waste

Srinivas Allena, 黑料社 Tri-Cities associate professor of civil and environmental engineering, received a contract to develop an ultra-high performance cementitious

material to potentially be used as a grout to encapsulate solid secondary waste from the Hanford tank farms.

鈥淲RPS is currently using a grout that they obtain from a local concrete supplier, which uses a regular cement mix with sand and some other chemical additives,鈥� Allena said. 鈥淏ut the goal with our research is to use locally available materials to create a composite with low permeability, superior durability and greater stability that would perform at the same level as the commercially available pre-packaged ultra high-performance concrete.鈥�

Allena said there is currently limited types of ultra high-performance concrete available on the market with high operational costs associated with use of the material. He said by using locally available materials and by optimizing mixture constituents with those that are more environmentally friendly with his team鈥檚 composite, however, they would be able to keep the costs low, while maintaining the same quality in the concrete and reducing the impact to the environment.

鈥淲e will be able to compare our grout materials with properties that WRPS is currently using and show the improved properties,鈥� he said. 鈥淭he goal is to provide a cheaper, more environmentally friendly option that will compete with the best product on the market.鈥�

The team plans to have initial mixtures ready with their mechanical and durability properties evaluated by September.

The projects are a part of solving some of the world鈥檚 . They pertain particularly to developing and by harnessing technology to improve quality of life. The projects are also in line with 黑料社鈥檚

RICHLAND, Wash. 鈥� A federal project director from the U.S. Department of Energy will discuss how the Hanford waste treatment plant will immobilize radioactive waste by turning it into glass as part of a continuing lecture series from 3-4 p.m. Thursday, Nov. 30, in the Washington State University Tri-Cities East Auditorium.

The presentation will be led by Jason Young, federal project director at the Office of River Protection鈥檚 analytical laboratory and balance of facilities office. The presentation is the fifth in a series of lectures focusing on the Hanford Site and is cohosted by 黑料社 Tri-Cities and the U.S. Department of Energy. The public is invited to attend.

During his presentation, Young also will describe how the 鈥渄irect feed low activity waste鈥� approach at the Hanford Site will enable treatment as soon as 2022. Additionally, he will outline the cooperative efforts needed to support their operations.

Young joined the Office of River Protection in 2008. He previously worked for the Puget Sound Naval Shipyard as a shift test engineer in the nuclear engineering division and later served as the reactor plant technical expert for the radiological emergency planning division.

Young holds a bachelor鈥檚 degree in chemistry from Lander University and a master鈥檚 degree in chemical engineering from Montana State University.
