Westinghouse Parts Business Overview, Parts Quality Program

January 3, 2023, 2:35PMSponsored ContentWestinghouse Parts Business


Safety and reliability have long been hallmarks of the commercial nuclear industry, which has averaged an annual capacity factor over 90% since 2012 and generates more than 775 GWh of clean energy each year (US EIA).

In an industry driven to continuously improve to maintain plant availability at high levels, equipment reliability remains a frequent subject of conversation between nuclear plant operators and suppliers. In September 2021, INPO released event report 21-4 titled “Improving Plant Reliability” and identified a steady trend in equipment-related events which resulted in lost generation of 38 million MWh between 2018 and 2022. These events were generally preventable and led INPO to make several recommendations to the industry, most notably one that challenged the industry to review and establish a “sustainable parts quality process”.

Decades of fuel performance data coupled with advanced analytics and multi-processor computing have enabled the development of ‘novel’ modeling & simulation tools that allow nuclear fuel engineers to predict behavior across the entire fuel cycle. With this new capability nuclear fuel designers and fuel reload managers are better equipped to predict performance and reliability. These tools are fundamental to communicating highfidelity safety margin assessments with the regulator, and, when applied in the early stage of reactor design, can achieve optimum safety system functionality. At the apex of the fuel performance codes development pyramid sit a triad of codes: SI’s Pegasus, DOE’s Bison, and CEA’s Alcyone, which share the commonality of three-dimensional modeling and simulation of nuclear fuel performance. Unique among the capabilities represented by these codes is the ability to bridge the encoded-technology gap between the frontend and the backend of the fuel cycle to eliminate sources of uncertainties in spent fuel safety evaluations. This capability is a distinguishing feature of the Pegasus code.

Contrary to what some believe, the nuclear industry, far from fading into the past, is experiencing an ongoing evolution. New generations of nuclear power technologies move closer to reality, while traditional nuclear generators are reaching retirement and entering decommissioning. As research on Small Modular Reactors (SMR) advances, prototype production is in full swing with the potential for SMRs to eventually replace the current fleet. And while technology advances, so do markets seeking to deal with the challenge of climate change in the face of the retirement of the currently operating nuclear power plants in the U.S. In an exceptional recent win for nuclear power, the Illinois legislature approved $700 million in subsidies for the Byron and Dresden nuclear stations over the next five years. It remains to be seen if this will be an isolated move in today’s nuclear plant lifecycle.


Digitalization of Work: A Key to Viability for Nuclear Power

October 1, 2021, 11:18AMSponsored ContentNextAxiom Technology

Work itself can be digitalized

Almost every aspect of work within a nuclear plant can be digitalized—from your frontline maintenance to back-end support functions. Digitalized work improves productivity, efficiency, and safety while substantially reducing costs.

From a work performance perspective, an organization can be defined as a collection of processes, often governed by regulatory policies. These processes are implemented using paper-centric procedures, work instructions, forms and checklists, often touching many hands during preparation, performance, and record management. This perspective applies to both direct powerplant operations and maintenance as well as administrative and support functions.

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.

Inspecting Hidden Areas of Metal Tanks and Containment Vessels or Liners

October 22, 2020, 11:35AMSponsored ContentSouthwest Research Institute
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.

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.
