Nuclear Power


over five years to help the Oregon-based nuclear power company develop its SMR design.


Nuclear fuel deliveries In Sweden, Westinghouse has been selected by OKG to provide replacement nuclear fuel deliveries for all three reactors at Oskarshamn units one, two and three. Te contract includes yearly deliveries of fuel for their reactors during the five-year period of 2016 to 2020. Under the terms of the contract,


Westinghouse will produce the fuel at its facility in Västerås, Sweden. Westinghouse has been a main fuel supplier to OKG, having already delivered nearly 8,500 fuel assemblies to the plants. All three boiling water reactors (BWR)


in Oskarshamn were designed and built by Asea-Atom, acquired by Westinghouse in 2000 (Fig. 1). Westinghouse is a single-source global nuclear fuel provider for pressurised water reactors (PWRs), including Russian-designed VVER reactors, as well as BWRs and advanced gas-cooled reactors (AGRs). Currently the company is fuelling 145 PWR and BWR plants, and has 10 nuclear fuel manufacturing locations around the world, including two sites in Europe: Springfields Fuels Limited in Preston, Lancashire, UK and Westinghouse Electric Sweden in Västerås. In another business development,


Westinghouse has confirmed a strategic partnership with Czech company


Vitkovice, in preparation for the potential construction of Westinghouse AP1,000 nuclear power plants in the Czech Republic. In accordance with the partnership,


Vitkovice will join the Westinghouse/ Toshiba/Metrostav team to jointly offer as a potential fabricator of key structural and mechanical equipment modules, should the AP1,000 reactor be selected to complete the expansion of the Temelin nuclear power plant.


Te AP1,000 has been designed to make use of modern modular- construction techniques that allow many more construction activities to proceed in parallel. Tis reduces the calendar time for plant construction, thereby reducing the cost of money and the exposure risks associated with plant financing. Areva has been selected by the operator of the Kozloduy Nuclear Power Plant to provide services for the safety instrumentation and control and electrical systems for Kozloduy units five and six. It will provide its expertise for the replacement or adaptation of the main electrical generators, which will provide a 10% increase in the output of each reactor. In other news, Areva has entered into a 50/50 JV with Japanese maintenance services specialist Atox. Known as Anadec, the new group will provide solutions in the field of decommissioning and dismantling of Japanese nuclear power plants. Tis JV expects to operate at the damaged Fukushima power plant. l


Sendai reactor changes sanctioned O


n 10th September, Japan’s Nuclear Regulation Authority (NRA) granted permission to Kyusyu Electric Power to make changes to the installation


of two reactor units at Sendai. It follows an application by the company in 2013, which was later followed up with a number of amendments earlier this year. “This is a regulatory step to grant permission for the basic design of nuclear reactors and related facilities applied from the operator. The applied design and safety features of Sendai units one and two and were deemed to meet the NRA’s new regulatory requirements,” said the NRA. Next, the NRA will review the detailed design and


construction of the nuclear reactors and related facilities as well as operational safety programmes including organisation systems and procedures for accident responses.


The NRA says its decision was a result of a careful review of the 18,600 page document from Kyusyu Electric Power, taking more than 110 hours all together, holding 62 review meetings and conducting field investigations for safety assessment.


All the meetings with NRA commissioners who are


in charge of earthquakes or reactor facilities were made public live via the internet. After released the draft assessment on facilities, the NRA collected opinions through the public comment procedures, reviewed these opinions and reflected them on the results of its assessment. In a separate development, the NRA says that 1,188


out of a total of 1,533 spent and unirradiated fuel assemblies in the unit four spent fuel pool area at the Fukushima Daiichi nuclear power station have been transferred to the common spent fuel pool on site. l

Magnox is responsible for decommissioning 10 Magnox reactor sites, located in England, Scotland and Wales, which were the first generation of civil nuclear power plants in the UK built during the 1950s and 1960s.


Westinghouse has confirmed an important strategic partnership with Czech company Vitkovice, in preparation for the potential construction of Westinghouse AP1,000 nuclear power plants in the Czech Republic. The AP1,000 makes use of modern modular-construction techniques that allow many more construction activities to proceed in parallel.
