Oak Ridge National Laboratory has a long record of advancing fusion and fission science and technology. Today, the lab is focused more than ever on taking advantage of that spectrum of nuclear experience to accelerate a viable path to fusion energy and to speed efficient deployment of advanced nuclear technologies to today’s power plants and future fission systems.

Nuclear I&C Modernization: The Future is Digital

June 4, 2021, 9:34AMSponsored ContentRobert Ammon, Technical Director of Digital Safety Systems at Curtiss-Wright Nuclear Division

As the U.S. nuclear industry moves into plant life extension and subsequent license renewals, the modernization of safety instrumentation and control (I&C) systems holds significant potential to transform plant operations. Automated system diagnostics, equipment health monitoring, and performance indications reduce the need for manual surveillance activities and enable condition-based maintenance, resulting in improved system reliability and reduced maintenance costs. Despite these benefits, adoption of digital I&C systems for safety-related applications across the domestic nuclear fleet has been slow. U.S. nuclear power plants that do choose to embrace the transition from analog to digital are in good company; international plants have successfully implemented digital safety systems for more than a decade. Furthermore, digital safety systems are also the first choice of the growing small modular reactor (SMR) and advanced reactor (AR) communities.

TRU Waste Solution inDRUM Treatment

May 27, 2021, 2:39PMSponsored ContentStudsvik

Do you have TRU waste with characteristics and/or prohibited items not acceptable in their current configuration for transportation and/or disposal at WIPP? Such as liquids, oxidizers, corrosives, reactive materials, flammable liquids, and aerosol cans? Are you sorting and segregating the non-compliant waste forms and then developing process/treatment approaches (i.e., solidification, grouting, deactivation, etc.) to ensure your final waste form will meet transportation and WIPP’s acceptance requirements?

Inspecting Hidden Areas of Metal Tanks and Containment Vessels or Liners

The Hanford Site in Washington state stores millions of gallons of high-level radioactive waste in 28 double-shell tanks. The tanks are buried underground to enhance radiation shielding. The space between the primary tank and the steel liner can be used to allow inspection of the inaccessible regions of these vessels.

Nuclear power plant containment vessels have large, inaccessible regions that cannot be inspected by conventional techniques. Inaccessible regions often are encased in concrete, soil or sand, or hidden behind equipment attached to a wall. Similar constraints affect the inspection of double-shell tanks designed to store nuclear waste, illustrated in Figure 1, that have an inaccessible region at the tank bottom where the primary shell is supported by the secondary shell. Present methods to monitor the integrity of these vessels primarily rely on partial inspections of accessible areas or estimation of corrosion rates; however, these approaches cannot account for nonuniform localized corrosion or cracking.

I&C vendor insights: safety digital technology selection to win the energy market

RadICS-based RPS-ESFAS system

Commercial nuclear power plants in the United States (U.S.) face tough competition from sources of alternative generation (e.g., solar, wind, etc.), cheap natural gas, especially in the unregulated market. It is recognized that 35 percent of the U.S. nuclear power plants, representing 22 percent of U.S. nuclear capacity, are at risk of early closure due to economic factors. Plant operators have been reluctant to adopt modern digital technologies for safety-related systems even though these technologies offer many benefits to improve safety and reliability, as well as achieve operating cost reductions.

Lead lined cabinets are utilized across a wide variety of industries including hospitals, nuclear medicine and the nuclear power industry. Some of the applications of shielded cabinets are for storing radioisotopes, radioactive waste, and providing shielding while operating x-ray tubes and protecting sensitive electronic devices from external radiation damage.

A simple, revolutionary approach to waste packaging

Addressing Current Problems

Bag-out operations can pose many issues to the TRU waste handling and disposal process. Among these are operator and facility safety, operational time, excess waste volume, and increased shipping costs to a waste repository.

Historically, removing hazardous waste from gloveboxes has involved using bags for primary containment. This bag-out method can prove tedious, repetitive, and time-consuming to ensure it follows all required safeguards to transfer waste without breaching containment. Layers of bags, yards of tape, and multiple filters are all added to the waste stream to transfer hazardous waste safely from the glovebox into a disposal drum.
