[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] 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] Summary: Considerations for safe Long Term Operation: • Extent to which the plant conforms to modern standards and practices; • Extent to which the (updated) licensing basis will remain valid; • Adequacy of arrangements to maintain plant safety; • Improvements to be implemented to resolve safety issues, including reasonably practicable modifications

[en] Nuclear power has safely, reliably, and economically contributed approximately 20% of the total electricity generated in the United States over the past two decades. High capacity factors and low operating costs make nuclear power plants some of the most economical power generators available. Further, nuclear power remains the single largest contributor (more than 60%) of non-greenhouse-gas-emitting electric power generation in the United States. The majority of commercial nuclear power plants in the United States have received a renewed operating license from the U.S. Nuclear Regulatory Commission (NRC), permitting those plants to operate up to 60 years. Further, the regulatory process permits licensees to seek approval from the NRC on extended nuclear power plant operations beyond 60 years. However, the NRC will require nuclear power plants that choose to apply for a second renewal of their operating license to demonstrate that adequate design and operational safety margins will be maintained over the extended operations period. In 2010, DOE’s Office of Nuclear Energy (DOE-NE) organized its research and development (R&D) activities in accordance with four objectives that ensure nuclear energy remains a compelling and viable energy option for the United States. Objective 1 focuses on developing the technologies and other solutions that can improve reliability, sustain safety, and extend the life of the current fleet of commercial nuclear power plants. The Light Water Reactor Sustainability (LWRS) Program is the primary programmatic activity that addresses Objective 1. The LWRS Program is focused on the following three goals: Developing the fundamental scientific basis to understand, predict, and measure changes in materials and systems, structures and components (SSCs) as they age in environments associated with continued long-term operations of the existing nuclear power plants, Applying this fundamental knowledge to develop and demonstrate methods and technologies that support safe and economical long-term operation of existing nuclear power plants, and Researching new technologies to address enhanced nuclear power plant performance, economics, and safety.

[en] Open-Cycle Cooling Water (OCCW) System of Qinshan Nuclear Power Plant (QNPP) was designed to supply sea water as the cooling water for heat exchangers of component cooling water system and emergency diesel generator (EDG) cooling water system. The main ageing mechanism of OCCW components with the environment of sea water includes corrosion, erosion, bio-fouling, aggressive chemical attack and sediment deposition, which would induce blocking, protective liner failure, corrosion perforation, reduction of heat transfer capability and jeopardize the safety and economical operation of plant. In order to reduce the risk of ageing degradation in OCCW system during the period of extended operating, the paper identifies the potential ageing degradation mode for OCCW components in QNPP, analyzes the insufficiency of the previous management measure, and investigated the coping strategy for each ageing degradation. Finally, the ageing management improvements of OCCW components are provided that include biocide treatment, system flow testing, disassembling inspection for critical equipment and heat transfer capability monitoring for safety important heat exchanger. These improvements have been applied in QNPP and proved effective in managing the ageing degradation of OCCW system. (author)
