[en] The Jordan Research and Training Reactor (JRTR) is Jordan’s first critical nuclear facility, owned and operated by the Jordan Atomic Energy Commission (JAEC). The reactor was successfully commissioned in 2016, has obtained its operating license from Jordan’s nuclear regulatory body, and is currently working on optimizing and extending its operation and utilization activities. In this work, prospects of utilizing the JRTR are presented by describing potential utilization applications suitable for the JRTR and of interest to its stakeholders, and afterward, challenges on the way of realizing and implementing those applications are discussed.

[en] Zion Nuclear Power Station (ZNPS) and the La Crosse Boiling Water Reactor (LACBWR) sites are both undergoing decommissioning. Although these two sites are different in terms of size, design, and operational history, the approach for defining release criteria for decommissioning at each site is similar. ZNPS consists of two (Units 1 and 2) Pressurized Water Reactors (PWR), each approximately 1100 MWe. ZNPS is located near the city of Zion in northeast Illinois on the west shore of Lake Michigan. The two units were operated from 1973 to 1998. LACBWR was an AEC Demonstration Reactor (50 MWe) which operated from 1967 to 1987. The LACBWR site is in Vernon County, Wisconsin and is shared with an operational fossil plant. EnergySolutions is managing the decommissioning of both these sites under the separate entities ZionSolutions and LaCrosseSolutions. The U.S. Nuclear Regulatory Commission (NRC) transferred the Zion Facility Operating License from Exelon Generation Company, LLC (Exelon) to ZionSolutions on September 1, 2010. A similar license transfer from Dairyland Power Cooperative to LaCrosseSolutions is planned for the second quarter of 2016. On December 19, 2014, ZionSolutions submitted the ZNPS License Termination Plan (LTP). It is expected that the LTP for the La Crosse BWR will be submitted to the NRC in early 2016. (authors)
[en] Challenge: Plant Economics: NPPs facing increased economic pressure leading to plant closures long before expiration of operating license (US) or potential plant life. E.g. recent & planed plant closures in US, in particular of single unit site NPPs of medium power range (< 600 MWe ) in unregulated. Also in Europe plant closures due to bad economics, e.g. Oskarsham 1 & 2 , Ringhals 1 & 2 (planed for 2020 2019), Muehleberg (planed for 2019).
[en] NPP Borssele is in operation since 1973. Based on a comprehensive LTO assessment in 2013 the plant received a license comprising operation until 2034 (60 years of operation). Within the LTO assessment a ageing management review was performed for all passive safety relevant Systems, Structures and Components. It could be proven that adequate ageing management activities are in place suitable for the planned Long Term Operation. Based on the outcome of the Ageing Management Review and international experiences it was decided to change the existing ageing management process into a more integrated approach.
[en] The MVM Paks NPP (hereafter: plant) being the only nuclear power plant in Hungary, is playing a special role in the energy-policy. The plant is a nationalized production capacity that is providing at around 40% of domestic energy production at the lowest price. The plant is an essential governmental property in the development of the national economy too and it is a potential tool for controlling the energy market as well. Also, the safe Long Term Operation (LTO) of the plant serves the conservation of intellectual and working potential of the country in the fields related with the use of nuclear energy. The above factors define the role of nuclear energy in the national energy policy and outline the strategy to be followed in the field of nuclear energy application in order to provide conditions for continuous development of the national economy. The IAEA's cooperation on the LTO preparation provided an international scientific and technical background by transferring the leading international knowledge related to safe LTO and practice to the License Renewal (USA). This cooperation also supervised the License Renewal Project's activities, documents and reports to check and verify the conformity to the best international practices. At the plant the LTO related tasks had been launched in 2000 and those will be accomplished by the end of 2017. During this term the plant received a couple of IAEA contributions for the extension of operation life of the plant (e.g. TC programmes, SALTO peer review missions, etc.) Additionally the results of the IAEA IGALL programme helped the development of the applied and currently used Aging Management Programmes (AMPs). The paper outlines these entire factors and describes the IAEA’s role for the successful licensing of the planned operational life extension. (author)
