TVA’s Browns Ferry Nuclear Plant is home to three boiling water reactors. Both the Sequoyah and Watts Bar nuclear plants have two pressurized water reactors. Collectively, these plants generate enough electricity to power more than 4.5 million homes and businesses. | (20491335) www.framatome.com | PreussenElektra GmbH orders 62 CASTOR® casks.

A total of 33 (Brokdorf ISF) and 34 (Grohnde ISF) loaded casks of this type are already in store in the local on-site interim storage facilities. | (20491220) www.gns.de Framatome signs multimillion-dollar contracts with Tennessee Valley Authority (framatome) Tennessee Valley Authority (TVA) awarded Framatome several multimillion-dollar contracts for work across the company’s reactor fleet. This includes fuel for the Browns Ferry Nuclear Plant, fuel handling equipment upgrades across the fleet and steam generator replacements at the Watts Bar Nuclear Plant. “Framatome’s long-standing relationship with TVA is the result of our U.S. and global teams’ expertise and commitment to delivering excellence in everything they do,” said Bernard Fontana, CEO of Framatome. “We are pleased to expand our cooperation with TVA and support them in providing efficient, reliable and low-carbon electricity to residents and businesses across the Tennessee Valley.” Framatome will provide its stateof- the-art ATRIUM 11 fuel for the three boiling water reactors at Browns Ferry with the first use planned for 2023. This contract makes TVA the third U.S. utility to switch to the ATRIUM 11 fuel design. ATRIUM 11 helps utilities to save money by using the uranium in nuclear fuel more efficiently. The fuel also allows operators to run their plants with more flexibility as demand fluctuates and other generation sources provide power to the electric grid. Framatome’s fuel fabrication facility, which recently celebrated its 50 th anniversary, in Richland, Washington, will manufacture the fuel. Framatome will also upgrade the fuel handling equipment at the Browns Ferry, Sequoyah and Watts Bar nuclear plants on an accelerated schedule, saving the plants both time and money. This work includes upgrading the refuel bridges at Browns Ferry, the manipulator cranes at both Sequoyah units and Watts Bar Unit 1, and the fuel transfer systems at Watts Bar. Framatome previously upgraded the fuel transfer systems at Sequoyah. The company will also replace the spent fuel bridges at Sequoyah and Watts Bar. Additionally, SGT, a joint venture between Framatome and AECOM, will replace four steam generators at Watts Bar Unit 2. In a nuclear energy plant, the steam generator has an essential role in producing electricity.

The acquisition represents a strategic investment in expanding the company’s nuclear products and services offerings. This acquisition supports Westinghouse’s global customer base through enhanced operating plant services, capabilities and technologies. It also strengthens the company’s digital innovation efforts. “Expanding our geographic footprint and strengthening our portfolio of systems and services is a key focus to better serve our clients and deploy innovative and leading solutions to the installed base of nuclear plants,” said Westinghouse President and Chief Executive Officer Patrick Fragman. “Both Westinghouse and Rolls-Royce Civil Nuclear customers will gain an expanded presence and benefit from synergies between our companies. With this strategic investment, we are enhancing our customer offerings in order to support their longterm operating goals to produce carbon- free, cost-effective and reliable energy.” News
atw Vol. 65 (2020) | Issue 3 ı March Through the transaction, Westinghouse will acquire the Rolls-Royce Civil Nuclear Systems and Services’ 11 locations in Canada, France, the United Kingdom and the United States. These sites support plant automation and monitoring systems, field services, manufacturing and engineering services as well as digital engineering services. These are key areas in supporting Westinghouse’s efforts to optimize customer planning and maintenance, and provide innovative systems and services to maximize performance, cost effectiveness and support life extension of the nuclear plants worldwide. All closing conditions have been met for Westinghouse to complete the acquisition. | (20491515) www.westinghousenuclear.com Operating Results November 2019 The first serial batch of MOX fuel loaded into BN-800 fast reactor at Beloyarsk NPP (tvel) BN-800, the world’s most powerful operational fast neutron reactor at Unit 4 of Beloyarsk NPP in Russia, has been loaded with the first serial batch of MOX fuel made of depleted uranium and plutonium oxides. After an overhaul, the power unit has successfully resumed operation. Distinct from traditional nuclear fuel with enriched uranium, MOX fuel pellets are based on the mix of nuclear fuel cycle derivatives, such as oxide of plutonium bred in commercial reactors, and oxide of depleted uranium which is derived by defluorination of depleted uranium hexafluoride (UF6), the so-called secondary tailings of uranium enrichment facilities. The power plant engineers have loaded eighteen MOX fuel assemblies at the BN-800 reactor core, while in 2020, Rosenergoatom and TVEL (i.e. power generation and nuclear fuel divisions of ROSATOM) are planning to load another batch of 180 fuel assemblies. By the end of 2021, ROSATOM is committed to replace all remaining uranium-based fuel assemblies in the core with MOX fuel. Thus, for the first time in Russian history, a fast neutron reactor would start operations with a full load of MOX fuel only. “ROSATOM strategy is aimed at the dual-component nuclear power system with both thermal neutron and fast neutron reactors, and closing nuclear fuel cycle, which would solve a number of highly important tasks.
