Chris Wagner has more than 40 years of experience in nuclear medicine, beginning as a clinical practitioner before moving into leadership roles at companies like Mallinckrodt (now Curium) and Nordion. His knowledge of both the clinical and the manufacturing sides of nuclear medicine laid the groundwork for helping to found Eden Radioisotopes, a start-up venture that intends to make diagnostic and therapeutic raw material medical isotopes like molybdenum-99 and lutetium-177.

The Nuclear Waste Technical Review Board announced it will hold a public meeting on Wednesday, August 27, to review information on the Department of Energy’s activities to manage spent nuclear fuel and high-level radioactive waste and to receive program updates from the DOE’s Office of Nuclear Energy.

Lightbridge Corporation has fabricated samples of nuclear fuel materials made of an enriched uranium-zirconium alloy, matching the composition of the alloy that the company intends to use for its future commercial Lightbridge Fuel product. The fuel is designed to improve the performance, safety, and proliferation resistance of nuclear reactors, according to the company. The enriched coupon samples will now be placed into capsules for irradiation testing in Idaho National Laboratory’s Advanced Test Reactor.

Employees at the Department of Energy’s Savannah River Site in South Carolina have demonstrated their resourcefulness and capabilities by implementing a newly created carrier to transport spent nuclear fuel, reducing the time needed to process the material for permanent disposal in coming years.

A study published by the Journal of the American Medical Association claims to have found an increased rate of cancer for people who grew up living close to Coldwater Creek near St. Louis Lambert International Airport in Missouri.

When I was 10, in October 1963, my family moved to Richland, Wash., so that my father could work for Vitro-Hanford Engineering Services, later for Bechtel, on the design of the Fast Flux Test Facility. I was a “new” kid throughout my excellent education in the Richland School District. It was the mid-1960s, and I wanted to be a rocket scientist or aerospace engineer. I took all the math and science that Richland High School (RHS) had to offer. What struck me during our tour of Hanford’s N-reactor with my physics class was the loudness of the steam turbine room compared to the hydro turbine rooms in the dams along the Columbia River. I am now establishing a residence on Columbia Point Drive in Richland.

The world’s first nuclear-powered merchant ship, the NS Savannah, will have a public site visit in Baltimore, Md., on Saturday, August 23.

A report just released by Idaho National Laboratory reviews decades of radiation protection standards and research on the health effects of low-dose radiation and recommends that the current U.S. annual occupational dose limit of 5,000 mrem be maintained without applying ALARA—the “as low as reasonably achievable” regulatory concept first introduced in 1971—below that threshold.

Noting that epidemiological studies “have consistently failed to demonstrate statistically significant health effects at doses below 10,000 mrem delivered at low dose rates,” the report also recommends “future consideration of increasing this limit to 10,000 mrem/year with appropriate cumulative-dose constraints.”

China has established a state-owned fusion energy company, China Fusion Energy Co. (CFEC), as a subsidiary of the China National Nuclear Corporation with the goal of accelerating the commercialization of fusion energy. According to a report by People’s Daily Online, the new company has a registered capital of 15 billion yuan (about $2.1 billion).

Caputo

Commissioner Annie Caputo is resigning from the Nuclear Regulatory Commission, according to a statement sent out to staff on Tuesday morning. Her resignation comes one day after the U.S. Senate voted to reconfirm chair David Wright to the commission.

“The time has come for me to more fully focus on my family,” Caputo said in her statement, provided by NRC spokesperson Scott Burnell. “I believe the [Trump] administration’s recent executive orders and the bipartisan ADVANCE Act have given the agency a platform for change.”

The nuclear industry is being pushed forward by a global tailwind that includes plans for more conventional nuclear plants and an exciting trend toward developing small modular reactors. These include advanced safety features and novel reactor designs, often powered by new types of fuel.

This new technology must meet existing stringent safety and security demands and must be safe for the environment, workers, and general population. Wide acceptance of international standards, as well as standardization of designs and plant concepts, will help in the long run.

Radiation protection (RP) professionals play a key role from the very start of the design phase. There is rapid and continuous development in the field of RP. Improved computational tools enable better modeling and understanding of radiation shielding, detection, and effects. Nuclear safeguards and nuclear criticality safety are increasingly important.

I have been a North Carolinian for 62 years and involved in the state’s nuclear energy industry from my high school days to today. I have seen firsthand how North Carolina has flourished. This growth has been due to the state’s enterprising people and strong leaders. Clean, competitive, and always-on nuclear power has also played an important role.

Munn

Nuclear engineer and longtime ANS member Wanda Munn died on July 23 at the age of 93. Described as a “trailblazer for women [and] an outspoken advocate for the peaceful use of nuclear technology” in her Tri-City (Wash.) Herald obituary, Munn followed a unique path to her nuclear engineering career. She did not get her degree until she was 46, and she subsequently spent 18 years working on systems design, construction, and operation of the Fast Flux Test Facility (FFTF) reactor for Westinghouse at the Hanford nuclear site in eastern Washington state.

Nontraditional student: Munn was born in 1931. She graduated high school early, at age 16, and started to pursue a medical degree. However, those plans changed when she married at age 18. By her early 40s, she was divorced and working as a secretary in a university nuclear engineering department when she decided to return to school to get a nuclear engineering degree.

The American Nuclear Society’s Risk-informed, Performance-based Principles and Policy Committee (RP3C) has held another presentation in its monthly Community of Practice (CoP) series. Former RP3C chair N. Prasad Kadambi opened the June 27 meeting with brief introductory remarks about the RP3C and the need for new approaches to nuclear design that go beyond conventional and deterministic methods. He then welcomed this month’s speaker: Tim Sande, a senior manager responsible for probabilistic risk assessments (PRA) and risk-informed engineering at Enercon, who presented “A Risk-Informed Framework for Managing Nuclear Facility Security Risks.”

The Nuclear Regulatory Commission has made three recent announcements regarding new developments in the nuclear energy industry:

Five of ANS’s past Congressional Fellows recently shared their unique experiences on Capitol Hill and gave insights into how they were able to have an impact on federal policy related to nuclear, exploring what they learned about the policymaking process and how ANS can continue having an impact in Washington.

The Department of Energy’s Manufacturing Demonstration Facility (MDF) at Oak Ridge National Laboratory, in partnership with Kairos Power and Barnard Construction, has successfully developed and validated large-scale, 3D-printed polymer composite forms for casting complex concrete structures.

The test took place at Kairos Power’s Oak Ridge, Tenn., campus, where the Hermes Low-Power Demonstration Reactor is currently under construction.

See a video of construction activity here.

The Palisades nuclear power plant has been formally transitioned from decommissioning status to holding an operating license following the completion of an extensive technical review by the Nuclear Regulatory Commission. It’s a historic move; before this, no U.S. nuclear plant had ever made the transition from shut down to approved for restart.

EnergySolutions has announced that it has been selected for the U.S. Navy’s Radiological Support Services (RADMAC III) multiple-award contract, valued at up to $240 million. EnergySolutions will lead a team that includes Tetra Tech EC and small business partners such as TerranearPMC, along with numerous others, to provide radiological response, investigation, and remediation services to the U.S. Naval Facilities Engineering Command Southwest.
