Alarms designed to detect a nuclear criticality accident at the Y-12 National Security Complex have been tested, and the systems functioned appropriately and as required, the plant said in November.

Y-12 has had a criticality accident alarm system since 1945. A criticality accident would occur if there were an uncontrolled nuclear chain reaction. It could result in the release of radiation and significant exposures to nearby workers if the area were not immediately evacuated. It’s something that the plant takes steps to avoid. The alarms are designed to alert workers if there is an accident.

A nuclear criticality alarm at the 811-acre plant, which works on nuclear weapons components and stores highly enriched uranium, has been given credit for helping to save lives in a nuclear criticality accident in 1958. In that case, which was the first process criticality accident in the United States, Y-12 employees immediately evacuated when they heard the alarm.

A report published by Consolidated Nuclear Security, a federal contractor, said the basic design and electronic configuration of the older criticality alarm system installed in Y-12’s existing facilities, with the exception of the Highly Enriched Uranium Materials Facility, date back to 1957. The legacy system has received many upgrades since installation, and detector stations have been removed and relocated as enriched uranium operations have evolved, said the report, titled “Qualification of Y-12 Legacy Criticality Accident Alarm System Detectors.” [Read more…]

The National Nuclear Security Administration is preparing to restart a program to replace the W78 nuclear warhead, and new facilities at the Y-12 National Security Complex could be important to that project, a federal agency said Friday.

The W78 is one of two types of warheads on U.S. Air Force intercontinental ballistic missiles. The W87 is the other.

Critical components inside the W78 are aging, according to the U.S. Government Accountability Office, which published a report about the warhead replacement program on Friday. Also, the military’s requirements for, among other things, the safety and security features of the warhead have changed since it entered the stockpile in 1979, the GAO said.

Besides being used by the Air Force, the replacement W78 warhead could be used in ballistic missiles launched from Navy submarines, although further studies are required, the GAO said.

The two Y-12 facilities that could affect the warhead replacement program are the Uranium Processing Facility, which is now under construction, and the Lithium Production Facility, which could have a new building through a project that is still in the planning stages. [Read more…]

Citizens calling for the abolition of nuclear weapons will gather in Oak Ridge on Saturday, August 4, at 10:30 a.m. at Alvin K. Bissell Park to commemorate the atomic bombing of Hiroshima, Japan, in 1945 and to call for the United States to sign and ratify the Treaty on the Prohibition of Nuclear Weapons, which was adopted in July 2017 by 122 nations, a press release said.

The Oak Ridge events on August 4 are sponsored by the Oak Ridge Environmental Peace Alliance, and they will include music and political theater as well as a report on ongoing nuclear weapons production activities at Y-12, the press release said.

“Y-12 represents the full circle in time,” said OREPA coordinator Ralph Hutchison. “The age of nuclear weapons started here, with the enrichment of the Little Boy bomb’s uranium. And it continues today, in the face of world condemnation, with the production of thermonuclear secondaries and plans for a new bomb production plant, the Uranium Processing Facility, which will continue to make nuclear bomb cores for decades to come.” [Read more…]

UPF lawsuit: NNSA considering new, supplemental environmental impact statement for Y-12

With a lawsuit pending, federal officials are considering whether a new or supplemental environmental impact statement is needed for the Y-12 National Security Complex after design plans changed for the Uranium Processing Facility, the largest federal construction project in Tennessee since World War II.

As part of the process, the National Nuclear Security Administration is preparing what is known as a supplement analysis, or SA. A draft of the new SA has been issued, and you can read it on the Y-12 website.

Comments on the draft supplement analysis can be submitted through June 20.

The final new supplement analysis and a record of decision could be issued by July 27, although the schedule is subject to change, according to a joint status report filed in U.S. District Court in Knoxville on May 11. The record of decision is expected to say whether a new or supplemental environmental impact statement is required for Y-12.

There was a site-wide environmental impact statement, or EIS, prepared for Y-12 in 2011. About five years later, in 2016, there was a supplement analysis prepared under the National Environmental Policy Act. It was connected to the decision by the NNSA and U.S. Department of Energy to not prepare a new or supplemental environmental impact statement after the NNSA decided on a new multi-building design for the UPF, rather than a single-building design, as part of an effort to keep project costs down, among other considerations.

The federal lawsuit that asks for an environmental review of the new multi-building design for the Uranium Processing Facility at the Y-12 National Security Complex has been transferred from Washington, D.C., to Knoxville.

The transfer of the civil complaint had been requested in September by the defendants, U.S. Energy Secretary James Richard “Rick” Perry and Frank G. Klotz, former administrator of the National Nuclear Security Administration. The NNSA is an agency within the U.S. Department of Energy that manages nuclear weapons programs and facilities, including Y-12, among other activities.

United States District Judge Dabney L. Friedrich, who was assigned the case in December, granted the motion to transfer the lawsuit from the District of Columbia to U.S. District Court for the Eastern District of Tennessee, which includes the Knoxville division, on March 23.

The 44-page federal lawsuit, which was filed in U.S. District Court in Washington, D.C., on July 20, argues that a new environmental impact statement should be prepared for the new design for the UPF, the largest federal construction project in Tennessee since World War II. The plaintiffs allege that the NNSA’s decision to use several new buildings for the UPF, rather than just one, and continue to use some old buildings at Y-12 for some nuclear weapons work is risky because the old buildings could collapse during a major earthquake, possibly leading to a nuclear accident that could release radiological materials.

Federal officials denied that allegation and others in a 29-page response filed September 29. They’ve called some allegations vague, ambiguous, or speculative, and they have said that safety and technical analyses are under way at Y-12. Some buildings may require seismic upgrades, depending upon evaluation results, and an Extended Life Program is meant to ensure that two buildings—Building 9215 and Building 9204-2E—will safely support future operations, federal officials said.

The federal spending bill approved last week includes $639 million for the federal government’s cleanup program in Oak Ridge, including what could be full funding for a top priority deactivation and demolition project at the Y-12 National Security Complex.

The $639 million for the current fiscal year is an increase of $141 million or more, compared to recent fiscal years, and it’s the most money appropriated in a while.

Besides Y-12, the fiscal year 2018 funding will be used for U.S. Department of Energy cleanup projects at East Tennessee Technology Park (the former K-25 site) and Oak Ridge National Laboratory.

“It’s very positive for us,” said Jay Mullis, manager of the DOE Oak Ridge Office of Environmental Management, or OREM. Mullis gave a brief update at a meeting of the Oak Ridge Reservation Communities Alliance on Monday.

In addition to $125 million to deactivate and demolish the Biology Complex at Y-12, the fiscal year 2018 spending bill includes $17.1 million in funding for the planned Mercury Treatment Facility at Y-12, about $200 million for continued cleanup work at ETTP, and a total of roughly $12 million for the Environmental Management Disposal Facility, or EMDF. That’s a proposed landfill that could be west of Y-12 and accept waste from future cleanup work at Y-12 and ORNL, possibly early in the 2020s. The project plan for EMDF is expected to be open to public comment later this summer. [Read more…]

Federal officials have authorized the start of construction of the three main buildings, including one for enriched uranium operations, at the Uranium Processing Facility at the Y-12 National Security Complex in Oak Ridge. It’s the largest federal construction project in Tennessee since World War II.

The authorization was announced Friday by the National Nuclear Security Administration, which is part of the U.S. Department of Energy. Y-12 is an NNSA site.

The authorization came from DOE leadership, NNSA said in a press release on Friday. The authorization allows the NNSA to start construction on the Main Process Building, Salvage and Accountability Building, and Process Support Facilities subprojects, the press release said.

UPF will replace an early-Cold War plant with a modern, more efficient, and safer facility for conducting highly-enriched uranium operations at Y-12, the NNSA said. Federal officials have been saying for a while that the facility is expected to be completed by 2025 at a cost of no more than $6.5 billion. [Read more…]

Trump administration requests more money for DOE, NNSA

The Trump administration has requested more money for the U.S. Department of Energy and National Nuclear Security Administration than it did last year, but the impact could vary at Oak Ridge’s major federal sites.

The NNSA, a semi-autonomous agency within DOE, would get a big increase of $2.2 billion, compared to spending levels enacted in fiscal year 2017. The boost would raise NNSA funding to $15.1 billion. The Y-12 National Security Complex in Oak Ridge is an NNSA site.

The NNSA proposal is more than $1 billion higher than the $13.9 billion requested by the Trump administration in fiscal year 2018, which was up $1.4 billion over the fiscal year 2016 spending level ($12.5 billion).

Oak Ridge Today reported last year that Y-12’s funding would have been up 25 percent under President Donald Trump’s budget request for the current fiscal year, if Congress had approved the proposed spending levels. [Read more…]

The National Nuclear Security Administration will have an information session on Wednesday about the Y-12 National Security Complex, the Uranium Processing Facility construction project, and the work to replace the electrical substation at Y-12.

The information session was scheduled after Oak Ridge officials raised concerns in November and December about the power lines proposed on top of Pine Ridge as part of the electrical substation project. Pine Ridge separates Y-12 from the center of the city, and Oak Ridge officials have said they had not received adequate notice of the power line project and didn’t know what other options had been considered. They also expressed concerns about the lack of public input and the visual impact of building power lines and installing transmission towers on top of the ridge. As of December, Oak Ridge City Council members said they hadn’t seen a visual representation of what the power lines could look like. [Read more…]

The City of Oak Ridge this week provided information on what the power poles on Pine Ridge could look like.

The logging work to install the power line poles, or transmission towers, on top of Pine Ridge has been temporarily delayed for 45 days after Oak Ridge City Council members raised concerns in November and December.

One of the concerns for City Council members has been the potential visual impact the power poles could have on top of Pine Ridge. That prominent ridge in south Oak Ridge separates Y-12 from the center of the city.

So far, the National Nuclear Security Administration and its Uranium Processing Facility Project Office haven’t provided a visual representation of what the transmission towers could look like on top of the ridge.

On Tuesday, Oak Ridge City Manager Mark Watson and Electric Director Jack Suggs provided some visual comparisons to City Council members during a non-voting work session. Watson said a light pole at the city baseball field is about 80 feet. That’s close to the same size as the roughly 79-foot-high power poles expected on Pine Ridge. [Read more…]

NNSA grants 45-day discussion for Pine Ridge logging, Y-12 power lines

The National Nuclear Security Administration has granted a 45-day discussion period for a project to build a new electrical substation at the Y-12 National Security Complex that could include logging work on top of Pine Ridge.

Oak Ridge officials had requested a 30-day delay of the logging work. City officials have raised concerns about that part of the project because they said they didn’t know about it until a week or two before logging operations were scheduled to start, there has been no public input, and cutting down trees and replacing them with transmission towers on top of the ridge would affect the view in that part of the city, including from two residential neighborhoods, Scarboro and Groves Park Commons. Pine Ridge is between Y-12 and the center of the city.

Oak Ridge officials have also said they don’t know what other options were considered, besides installing the high-voltage power lines on top of Pine Ridge.

The 161-kilovolt power lines will provide electricity to a new electrical substation that will service all of Y-12, but it is being built as a subproject of the Uranium Processing Facility. It would be near UPF on the west side of Y-12. UPF is the largest federal construction project in Tennessee since World War II, and it is expected to be completed by 2025 at a cost of no more than $6.5 billion.

Oak Ridge officials have emphasized that they support the project, but they don’t think the city has been treated as an equal partner on the electrical substation and power line portion of the project.

In a press release Tuesday, the City of Oak Ridge said the electrical substation project would involve clear-cutting 2.1 miles of mature trees along the top of Pine Ridge. The NNSA has delayed that project for 45 days, although some logging activity will still occur during that time. [Read more…]
