‘Diligent’ engineer discovers Y-12 water line break that spilled six million gallons

East Fork Poplar Creek

East Fork Poplar Creek starts at a spring at the Y-12 National Security Complex and flows through Oak Ridge. About six million gallons of water spilled into it in early June, killing several thousand small fish, after a 10-inch water line ruptured at Y-12.

The break in a 10-inch water pipe at the Y-12 National Security Complex on a Friday night in June—it spilled about six million gallons of water and killed several thousand small fish—was discovered by a diligent engineer who had returned to the plant to check on an abnormal water tower report, officials said.

The Defense Nuclear Facilities Safety Board reported that the plant contractor’s utilities and environmental compliance organizations both had had indications of an abnormal condition, but B&W Y-12 had not established a procedure to respond to the signals.

“The break was discovered because a diligent system engineer decided to come back in to the site and check on an anomalous report of a low level in a water tower that had cleared as the pumps refilled the tank,” the DNFSB report said. “B&W management is evaluating ways to improve recognition of a problem from the available indications during off hours.” [Read more…]

Teachers at Y-12 Labs

Daryl Smith, a Y-12 National Security Complex scientist, shows East Tennessee teachers that a balloon will shrink when dipped in liquid nitrogen during a “show and tell” laboratory on Friday.

In one room, bananas became brittle and snapped in clean lines after being dipped in super-cold liquid nitrogen.

In another room, teachers pedaling on a stationary bicycle with a generator attached learned it takes much more energy to power an incandescent light than compact fluorescent or LED bulbs.

The teachers were at the Y-12 National Security Complex on Friday for “show and tell” laboratories, learning experiments from Y-12 engineers and scientists that they could take back to their classrooms. It was part of the Innovation Valley’s Educators in the Workplace Lunch and Learn summer program. [Read more…]

B&W Y-12 recently signed agreements with two new protégés—BES Technologies and The Molecular Group. The companies join eight other groups currently involved in Y-12’s Mentor-Protégé program.

“We are proud to have these two participants in our Mentor-Protégé program,” said B&W Y-12 President and General Manager Chuck Spencer. “These relationships significantly contribute to Y-12 achieving its objectives of promoting technological growth and business development opportunities. I believe that all parties will benefit from these partnerships.” [Read more…]

U.S. Rep. Diane Black, a Republican from Tennessee’s 6th District, visited Oak Ridge National Laboratory Monday afternoon.

Black received an overview of the lab’s research and development activities and toured the Oak Ridge Leadership Computing Facility, the EVEREST Visualization Lab, the Consortium for Advanced Simulation of Light Water Reactors facility, the Spallation Neutron Source, and the Carbon Fiber Technology Facility.

Here are a few pictures provided by ORNL. [Read more…]

There has been significant movement in both the House and Senate on the pending legislation to create a national historical park for the Manhattan Project at Oak Ridge as well as Los Alamos, N.M., and Hanford, Wash.

On June 14, the House of Representatives voted to include the Manhattan Project National Historical Park Act as an amendment to the National Defense Authorization Act (NDAA), H.R. 1960. A few hours later, the House passed the NDAA and, along with it, the Manhattan Project National Historical Park Act. The Manhattan Project Park Act, and the NDAA amendment, was sponsored by representatives Doc Hastings (R-WA), Ben Ray Lujan (D-NM), and Chuck Fleischmann (R-TN).

The same day, the Senate Committee on Armed Services completed its markup of the National Defense Authorization Act (NDAA) for Fiscal Year 2014. Next, the full Senate must pass the bill. Once the Senate acts, a House-Senate conference committee will be appointed to reconcile differences between the two versions of the NDAA. [Read more…]

Y-12 neutron detector wins R&D 100 Award

A Y-12 nuclear nonproliferation technology offering significant possibilities in the homeland security field was among those listed on the R&D Magazine 51st Annual R&D 100 Awards. The honor salutes the 100 most technologically significant products introduced into the marketplace during the past year.

The LISeTM, a high-efficiency thermal neutron detector based on the 6LiInSe2 crystal, is the first large, single-crystal semiconductor of high resistivity that contains lithium and directly detects thermal neutrons with high efficiency. The single-crystalline device will be used in handheld nuclear nonproliferation and homeland security applications to find fissile materials. Its simpler, more compact design, and higher efficiency are key improvements that will appeal to users. [Read more…]

Peace group wants fence removed from longtime Y-12 protest area

Y-12 Fence on Scarboro Road

The temporary fence erected at the main entrance to the Y-12 National Security Complex encloses an area, pictured above, that has been used for protests and vigils for years. An Oak Ridge organization that wants to eradicate nuclear weapons has asked a federal court to order the removal of the fence before an Aug. 6 ceremony.

Calling it an assault on their First Amendment rights, an Oak Ridge organization has again asked a federal court to order officials to remove a fence that blocks an area long used for protests, vigils, and demonstrations in front of the Y-12 National Security Complex.

The Oak Ridge Environmental Peace Alliance, which opposes Y-12’s nuclear weapons production work, filed the preliminary injunction in U.S. District Court in Knoxville on Friday. The lawsuit, which amends a complaint filed in April, names new U.S. Energy Secretary Ernest Moniz as the sole defendant.

OREPA wants the U.S. Department of Energy to reopen a small grass field near Y-12’s main entrance at East Bear Creek and Scarboro roads before an annual Aug. 6 demonstration. If it is left in place, the temporary fence erected April 1 would cause “irreparable harm” to First Amendment rights—including the rights of free speech, peaceful assembly, and the ability to petition the government for a redress of grievances, OREPA said.

Official in the United States, Vietnam, and Russia announced this month that they have removed 11 kilograms of highly enriched uranium, or HEU, from the Dalat Nuclear Research Institute in Dalat, Vietnam.

“With this shipment, the Socialist Republic of Vietnam became the eleventh country from which all HEU has been removed since President Obama’s 2009 announcement in Prague of an international effort to secure all vulnerable nuclear material around the world,” the U.S. Department of Energy’s National Nuclear Security Administration said in a press release. “The U.S. will work with our international partners to remove the remaining HEU from another country by the end of 2013 in support of this global effort and the goals of the Nuclear Security Summits.” [Read more…]

The Consortium for Advanced Simulation of Light Water Reactors this week announced that its scientists have successfully completed the first full-scale simulation of an operating nuclear reactor.

Headquartered at Oak Ridge National Laboratory, CASL is modeling nuclear reactors on supercomputers to help researchers better understand reactor performance with much higher reliability than previously available methods, with the goal of ultimately increasing power output, extending reactor life, and reducing waste.

Simulation results from the Virtual Environment for Reactor Applications (VERA) program, which was developed by CASL, were compared with actual data provided by the Tennessee Valley Authority’s Watts Bar Nuclear Plant in Tennessee, which confirmed its accuracy. [Read more…]
