The Nuclear Regulatory Commission (NRC) has approved Framatome's AURORA-B AOO methodology, which will allow plants to analyze a wide range of events required for licensing. Additionally, it will help operators maximize the value from the company's new ATRIUM 11 fuel assembly design. Approval of this tool is a major milestone in bringing the next-generation fuel technology to the market.

Fuel assemblies are a grouping of metal-clad fuel rods that produce the energy generated by nuclear reactors. Due to the nature of the materials, and demanding conditions, accurate modeling is essential to assure safety margins are maintained by using detailed data, methods, and models.

"Requirements of the new energy economy translate to expanding demands on our nuclear operators," said Bob Freeman, vice president of the Commercial and Customer Center for the Fuel Business Unit of Framatome Inc. "Framatome is committed to developing the technology and tools our customers need to generate electricity reliably, flexibly and efficiently."

The AURORA-B AOO methodology analyzes all potential events required to license ATRIUM 11's use in boiling water reactors. Its enhanced capabilities deliver precise, multi-dimensional modeling and handle complex fuel configurations.

Additionally, its state-of-the-art techniques provide customers with a better understanding of their unique plant's response to a wide range of events and establishes ideal operating limits for reloads of ATRIUM 11 fuel.

Pending final licensing approval of all necessary methods and codes by the NRC, ATRIUM TM 11 is scheduled for commercial use in spring of 2020. Upon coming to the market, operators will implement AURORA-B AOO as part of the technical basis for utilizing the fuel assembly design in their units.

Nuclear safety: AREVA develops an innovative technology for reactor inspection
Paris, France (SPX) Apr 05, 2018
AREVA has developed a cutting-edge technology for nuclear reactor vessel inspections that optimizes both the safety and reliability of operations. The automated tool, known as Lower Girth Weld Inspection Tool (LGWIT), allows plant personnel to remotely perform inspections through narrow gaps of the reactor vessel internals. The tool's remote operation replaces the need for direct human intervention. This is both more efficient and contributes to significant cost savings for each inspection perform ... read more
