Several NNSA employees had the opportunity to meet and mingle with President Obama and First Lady Michelle Obama yesterday on the South Lawn of the White House. The event drew more than 1,000 employees from throughout the federal government. Seen here is Will D'Ercole, son of NNSA Director of Congressional Affairs Jed D'Ercole.
Lawrence Livermore National Laboratory researchers have for the first time simulated and quantified the early stages of radiation damage that will occur in a given material. A full understanding of the early stages of the radiation damage process provides knowledge and tools to manipulate them to the fullest advantage.
Nuclear radiation leads to highly energetic ions that can penetrate large distances within matter, often times leading to the accumulation of damage sites as the projectile passes through the material.
During this process, the energetic ions eventually slow down as energy is lost by friction with the materials’ electrons. Like a speedboat moving through a calm body of water, the passage of fast ions creates a disturbance in the electron density in the shape of a wake.

The resulting change in electronic density is responsible for modification of chemical bonds between the atoms and consequently for a change in their interactions.
Maintenance Support and Utilities Management personnel at NNSA's Y-12 National Security Complex have taken steps to make sure old utility poles aren’t sent to the landfill. The Tennessee Department of Agriculture’s Forestry Division and Y-12 staff collaborated to deliver utility poles to Lone Mountain State Forest’s parking lots.
Mike Disney, Y-12 Power Operations section manager, said, “It’s good that we can help other agencies, save tax dollars, and help save the environment all at the same time. Opportunities like this don’t happen very often.”
After the old utility poles were inspected and approved for off-site use, six forestry service employees brought five lumber trucks on site in October 2011. Y-12’s line crew cut the 90-foot poles into smaller sections and helped load the trucks. The lumber trucks eventually hauled away more than 100 poles.
Cables pass through holes in waist-high sections of the poles, creating a border and confining vehicles and horse trailers to designated parking areas. In the near future, forestry personnel will use some of the poles as structure posts for a much-needed pavilion that will provide cover for Morgan and Roane County wildland firefighting equipment. Other sections of the poles will be used to block motorized vehicles from using the horse trails.
Additional uses for the old poles have been found. The U.S. Department of Energy is using some of the old poles at its secure transportation courier training facility in Oak Ridge. Some of the poles have been used to build a façade for a bunker on a live firing range. Additional poles have been stockpiled, and a combat conditioning course will be built as soon as funding is provided.
Pantex volunteers recently made lunch for 350 honor roll students as part of the plant’s ongoing efforts to support academic achievement in area youth, particularly in areas such as science and math. This is the second year in a row Pantex has cooked lunch for the A and A-B honor roll students from Sam Houston Middle School in Amarillo.
Thanks to Sandia technology, radioactive material from more than 43 million gallons of contaminated wastewater have been removed at Japan’s damaged Fukushima Daiichi nuclear power.
Sandia developed a technology that uses crystalline silico-titanate, or CST, as a molecular sieve that can separate highly volatile elements from radioactive wastewater.
The CSTs were developed in the early 1990s response to a need for materials to remove radioactive contaminants from wastewater. During that time, researchers found that a certain class of synthetic zeolite is more effective in capturing some radioactive elements, like cesium, than other technologies.

Members of the B&W Pantex Explosives Technology Division celebrated a significant safety milestone Thursday with a cookout to commemorate working three million man hours without a lost time injury.
Managers from the division grilled up lunch for approximately 150 workers to mark the achievement, which is made even more significant by the nature of the work done by Explosives Technology employees.
According to David Cole, acting division manager, safety is the absolute priority for Pantex and it is something they talk about every day.“Explosives operations are a high-consequence area,” he said. “If you have a mistake, the consequences can be very grave. We have to make sure we never forget that and never become complacent.”
Explosives Technology staff have worked diligently to make sure everyone works safely, said Monty Cates, manager of the Materials and Analytical Services Department. At daily standup meetings, safety is always the first topic, and every month, department safety meetings are held. Explosives Technology staff also participate in the many safety programs that operate plant wide.
B&W Pantex Acting Deputy General Manager Rod Johnson said the fact the Explosives Technology Division was able to achieve such a milestone is testament to the dedication of the staff. “Safety, security and quality are the basis of all of our activities at Pantex,” he said.
The hard work of the members of the division led to Pantex being named the High Explosives Center of Excellence for High Explosives Manufacturing by the Department of Energy.
Some 345 tons of steel came tumbling down yesterday as a world record was set at the Nevada National Security Site (NNSS), when a 1,527-foot steel tower used in above-ground nuclear experiments in the 1960s was demolished.
The BREN (Bare Reactor Experiment -- Nevada) Tower was the tallest structure of its kind ever to be brought down. The tower was taller than the Empire State Building (1,454 feet, to the top of lightening rod) and taller than the Stratosphere Tower in Las Vegas (1,148 feet).
The tower was brought down due to safety concerns for personnel working nearby and risk to aircraft flying in the area. Contributing factors included lack of use, maintenance issues, and an uneconomical cost of more than $1 million that would have been required return the tower to a usable state.
DEMCO, Inc. of West Seneca, N.Y., partnered with Controlled Demolition, Inc. of Phoenix, Md., to bring down the tower. Because the tower was so tall, highly controlled demolition techniques were employed. Explosives were used to remove a small section of one leg of the tower at ground level and sever the tensioned guy wires and the anchor/stanchions on the opposite side.

John Mitsunaga from NNSA's Los Alamos Site Office (LASO) has been named as a New Mexico Federal Employee of the Year by the New Mexico Federal Executive Board. His award is listed in the Professional, Administrative and Technical category.
Mitsunaga, a physical security specialist for LASO, also has a federal role in the lab’s Emergency Operations Center where he ensures the security and protection of sensitive assets on lab property.
Additional accomplishments for which Mitsunaga was recognized include oversight for technical security requirements for a sizable construction project that will provide state of the art security protection for the lab’s plutonium facility. He was also instrumental in obtaining funding to modernize protective force training facilities necessary to enable them to protect special nuclear material. The funding included construction of indoor and outdoor shooting ranges, a tactical training facility and a fitness track.
NNSA has approved a special tooling system designed to improve the processing time of the B83. The tools were created by NNSA’s Pantex Plant and announced last fall. See press release here.
The tooling system for the B83 program is now part of NNSA’s Seamless Safety for the 21st Century (SS-21) process. The SS-21 process fully integrates the weapon system with the facility, tooling, operating procedures and personnel involved in the dismantlement program to form a safe, efficient and effective operating environment. The SS-21 process has been incorporated into all current Pantex weapon programs.
Approval for the special tooling system took a few months longer than originally expected because of the rigorous approval process. Final tools were delivered and the Hazard Analysis Report was published and approved by Pantex Site Office. In addition, the Nuclear Explosive Safety Study was conducted with no pre-start findings.
The goal of the project was to streamline the B83 disassembly and inspection and dismantlement processes. The new tooling process is designed to have multi–purpose functions, which includes the ability to support future B83 assembly operations.
The tooling system supports a safe, secure and effective strategic deterrent and is being used to support stockpile surveillance and dismantlement work. The new tooling system will be used to support the upcoming concurrent retrofit of the Gas Transfer System and Neutron Generators (ALT 353/753 respectively), scheduled for first production to occur in July 2014.
The B83 program team includes members from Lawrence Livermore National Laboratory, Pantex Plant and Sandia National Laboratories.
