April 2, 2021, 6:56AMRadwaste Solutions

The Waste Isolation Pilot Plant's underground repository in New Mexico was evacuated for 13 days in March following an incident at Los Alamos National Laboratory, where a drum being packed with transuranic waste began emitting sparks.

As reported on March 31 by the Carlsbad Current Argus, an evacuation order was given on March 5 after WIPP was informed by the National Nuclear Security Administration that similar at-risk drums from LANL were emplaced for disposal in the repository. The order was lifted on March 18 after it was determined that the drums were compliant with WIPP’s waste acceptance criteria and did not pose a risk.

A community advisory board has been formed for the decommissioning of Unit 2 of the Three Mile Island nuclear power plant, according to a March 23 report by StateImpact Pennsylvania, a collaboration of National Public Radio member stations. The Nuclear Regulatory Commission approved in December the transfer of TMI-2 and its license to TMI-2 Solutions for decommissioning. TMI-2 Solutions is a subsidiary of EnergySolutions.

According to the report, the TMI-2 Community Advisory Panel (CAP) is made up of 15 people who represent the plant and its neighbors, including townships, school districts, first responders, nuclear planners, and state historians. The group is being led by Londonderry Township manager Steve Letavic.

TMI-2 Solutions said that it will provide quarterly decommissioning updates to the TMI-2 CAP. As a volunteer non-regulatory organization, the CAP will provide community feedback to TMI-2 Solutions, including any issues or concerns related to TMI-2 decommissioning activities.

The month of March marked the 25th year of radiological operations for the Defense Waste Processing Facility (DWPF) at the Department of Energy’s Savannah River Site in South Carolina. Radiological operations at DWPF, which is used to treat Savannah River’s high-level radioactive tank waste, began on March 12, 1996, with the first canister of vitrified waste poured on April 29 that year.

To date, more than 4,200 stainless steel canisters of vitrified waste have been poured at DWPF, according to the DOE.

The only operating waste vitrification plant in the nation, DWPF is operated by Savannah River Remediation, the DOE’s liquid waste contractor at the site. According to the DOE, DWPF operations are expected to continue for approximately 15 more years, and about 4,000 more canisters are scheduled to be produced. The DOE expects to begin hot operations at a second waste vitrification plant later this year at its Idaho National Laboratory site.

The first wall section of Saltstone Disposal Unit 8 (SDU 8) at the Department of Energy's Savannah River Site in South Carolina was installed earlier this month.

SDU 8 will stand 43 feet tall and 375 feet in diameter, and have a 33-million-gallon capacity, just like two SDUs built recently at the site. The 25 wall sections of SDU 8 are being constructed using high-strength, reinforced concrete and will be wrapped with seven layers of more than 300 miles of steel cable for added strength.

The flooring of SDU 8 is more than halfway complete. The concrete floor sits on top of a multilayer foundation: a geosynthetic clay liner and high-density plastic liner sandwiched between two concrete layers called “mud mats.” The floor is being completed in 14 sections.

The disposal units are built to safely and permanently contain decontaminated salt solution processed at Savannah River, the DOE reported on March 9.

Holtec International said that it successfully loaded its 1,500th spent fuel canister last week as part of the ongoing dry storage campaign at Ameren Missouri’s Callaway Energy Center. Holtec’s HI-STORM UMAX subterranean dry storage system has been in service at Callaway since 2015. The MPC-37 multipurpose canister is used to place 37 pressurized water reactor spent fuel assemblies into each HI-STORM UMAX vertical ventilated module.

“There has been a strong collaboration between our teams, and I truly appreciate the strong focus on doing the work safely, correctly, and to the highest standards of excellence,” said Fadi Diya, senior vice president and chief nuclear officer of Ameren Missouri, in a March 17 announcement.

“Just as we shared the milestone in 2015 of deploying the world’s first subterranean dry storage system under a general license, we are proud to share this milestone with Ameren,” said Pierre Oneid, Holtec’s senior vice president and chief nuclear officer.

Southern California Edison pushes to get SONGS’s spent fuel moved off-site

March 16, 2021, 3:00PMRadwaste Solutions

Southern California Edison has released a three-volume set of plans supporting the off-site relocation of the spent nuclear fuel currently stored at the San Onofre Nuclear Generating Station. According to SCE, the release of the Action Plan, the Strategic Plan, and the Conceptual Transportation Plan constitutes a significant milestone in a process that began with the 2017 settlement regarding the coastal development permit issued for San Onofre’s expanded spent fuel storage installation.

At the same time, in an effort to urge the federal government to find a permanent solution to the nation’s inventory of commercial spent fuel, SCE and the counties of Orange and San Diego announced on March 15 the formation of a stakeholder coalition, Action for Spent Fuel Solutions Now.

“SCE and our partners and stakeholders have a genuine opportunity to bring people together with a shared interest to prepare and advocate for the relocation of the spent fuel away from the coast,” said Kevin Payne, SCE’s president and chief executive officer. “It is clear that to make tangible progress on this issue, the federal government must act. Rather than wait for this to happen, we are going to be a catalyst for change.”

Information about the coalition, including how to join, is available on its website.

2021 WMS: “No margin for error” in shipping radwaste

Eiler

Noting that an increasing number of large components will need to be shipped from the growing number of nuclear power plants being decommissioned, Todd Eiler, director of decommissioning and decontamination engineering projects at EnergySolutions, said that the safety of nuclear waste transportation is paramount. “It is imperative as an industry that we do these shipments safely. There’s really no margin for error here,” Eiler said on March 11 during the 2021 Waste Management Symposia virtual conference panel session “Efficient and Effective Waste Management During the D&D of Nuclear Power Plants.”

While noting the stellar safety record of the nuclear industry in transporting radioactive waste, Eiler said that any incident involving a large component from a decommissioned nuclear reactor will cause national headlines, and that the industry needs to adopt a conservatism above and beyond what is already required by regulations.

As plant owners and decommissioning companies prepare to ship reactor components for disposal, Eiler said, entities that do not have direct regulatory oversight but may have some secondary involvement should not be overlooked. As an example, he said that when moving the San Onofre-1 reactor pressure vessel to Utah for disposal, EnergySolutions was not required by regulations to coordinate with the Federal Railroad Administration. “However, they are a stakeholder that definitely has authority over a project of that magnitude [where] you are transporting an irradiated component on the nation’s most in-demand rail infrastructure,” he said, adding that getting the administration’s input early in the project was important.

WMS2021 panel finds challenges, opportunities in COVID-19

March 11, 2021, 3:10PMRadwaste Solutions

It has been more than a year since the COVID-19 virus fundamentally changed our daily lives, but with mass vaccinations underway, it is now possible to see a light at the end of the tunnel. The past year presented many challenges, as well as new opportunities, and this was the focus of discussion during the panel session “Strategies to Increase Efficiency, Reduce Cost, Accelerate Work, and Maintain Operational Excellence,” held on March 10 during the 2021 Waste Management Symposia virtual conference. “Last year was a tough year for all of us,” said John Eschenburg, president and chief executive officer of Washington River Protection Solutions, the Department of Energy’s liquid waste contractor at the Hanford Site, near Richland, Wash. “[There were] challenges top to bottom.”

Some of the challenges the session speakers said they faced included transitioning personnel to working remotely, ensuring safety with reduced on-site staff, and reducing workplace stress caused by the pandemic. Yet, the panelists found lessons learned from the pandemic that have created opportunities for positive change, such as the ability to reduce overhead costs while offering staff better a work/life balance by continuing to allow remote working where possible post-pandemic. “Teleworking is here to stay at some level,” Eschenburg noted.

William “Ike” White, the Department of Energy’s acting assistant secretary for environmental management, helped open the 2021 Waste Management Symposia by announcing a new era for the department’s Office of Environmental Management (EM) and its cleanup mission. Speaking via live stream during the virtual meeting’s plenary session on March 8, White said, “Today, EM is at the start of a new era, with a new administration and a new set of priorities for the year, and, hopefully, the start of a new post-pandemic world.”

The new priorities that White touted are contained in EM’s Calendar Year 2021 Mission and Priorities, which outlines specific planned goals across the cleanup complex for the coming year. According to the DOE, the calendar serves as a marker for EM’s continuing success in addressing the legacy of nuclear weapons production and government-sponsored nuclear energy research.

Jacobs to assist in one of world’s deepest nuclear cleanup missions

March 5, 2021, 9:29AMRadwaste Solutions

Dounreay Site Restoration Ltd. (DSRL) has awarded a six-year contract worth an estimated $10.4 million to engineering company Jacobs to lead an integrated design management team for one of the world’s deepest nuclear cleanups. The team will help in coordinating the program to clear and treat radioactive waste in the shaft and silo at Dounreay, near Thurso, in Scotland, U.K., a former fast reactor research and development center.

The Dounreay shaft extends 214.5 feet below ground and measures 15 feet wide in places, while the silo is a large underground vault with a concrete roof. Both were used for disposal of intermediate-level radioactive waste in the 1960s and 1970s, but now the solid waste and liquid effluent they contain needs to be retrieved and repackaged for removal to a safe, modern storage facility.

DSRL, the site decommissioning company, has tasked Jacobs with leading design integration ahead of the start of construction work. The company will also assist with the management of design and build work packages and offer design support during construction and commissioning. In announcing the contract on March 4, Jacobs said that it will subcontract with Berkshire Engineering, which is based near Dounreay, to assist with test and trials work.

Savannah River Site moves closer to closing F Tank Farm

March 3, 2021, 12:02PMRadwaste Solutions

Workers at the Savannah River Site’s F Tank Farm (FTF) are preparing to close radioactive waste tanks, according to a March 2 release from SRS. The last time a waste tank was closed at the farm was in April 2016.

The FTF is a 22-acre site that contains 22 of the 51 tanks spanning two SRS tank farms. (The separate-site H Tank Farm houses the remaining 29 tanks.) The FTF’s 22 tanks are below-grade, carbon steel and reinforced concrete tanks that store or previously have stored liquid radioactive waste generated at SRS, in South Carolina.

The Department of Energy’s Office of Environmental Management (EM) has issued a draft request for proposals for the new Integrated Tank Disposition Contract at the Hanford Site near Richland, Wash. The 10-year, $26.5 billion contract will replace the Tank Operations Contract currently held by Washington River Protection Solutions, and the scope will be expanded to include the operation of the Waste Treatment and Immobilization Plant (WTP) after radiological, or “hot,” commissioning of the plant is completed.

The DOE had awarded a tank closure contract to a team led by BWX Technologies in May of last year, but later rescinded that decision after protests were raised by the two losing contract bidders.

About 56 million gallons of radioactive waste is contained in Hanford’s 177 aging underground tanks. The WTP, which is still under construction, will vitrify the waste after it has been separated into low- and high-activity waste streams.
