Nuclear Engineering and Technology (NET), an international journal of the Korean Nuclear Society (KNS), bimonthly publishes articles related to the theory and application of nuclear science and technology. The purpose of the NET journal is to disseminate technical information on nuclear engineering and related disciplines that are of lasting interest to the general engineering community. The NET publishes original research and review papers and technical notes in English. All submitted papers and technical notes will be reviewed for technical content. It is understood that the paper has been neither published nor currently submitted for publication elsewhere. The copyright of all published papers and notes will be vested in KNS. No article can be published unless accompanied by a signed publication agreement which specifies a transfer of copyright from authors to KNS and author responsibility for protecting proprietary and third-party rights. NET covers all fields of nuclear engineering for peaceful utilization of nuclear energy and radiation. Authors should choose one of the following review fields at the time they submit their manuscript: 1) Reactor Physics 2) Thermal Hydraulics 3) Nuclear Safety 4) Nuclear Instrumentation and Control 5) Nuclear Physics, Fusion, and Laser Technology 6) Nuclear Fuel Cycle and Radioactive Waste Management 7) Nuclear Fuel and Reactor Materials 8) Radiation Applications and Shielding 9) Nuclear Structural Analysis and Plant Management & Maintenance 10) Human Resource Development and Energy Economics & Policy
