ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

This paper describes a radiation sensor network system that can remotely monitor accidental area covered by high radiation in nuclear facilities. Each radiation sensor node is designed with radiation detector, radiation hardened readout circuit, microcontroller, and wireless communication module. In this paper, we will discuss sensor and circuit design configurations as well as initial radiation test results of a commercial wireless sensor module to verify how it works with the increase of irradiation doses. The measured data will be used to design a radiation hardened wireless communication system that can provide the most important information of monitoring radiation dose in accident nuclear sites where they are leaked in unseen area to mitigate such a severe accident situation in the very early stage. According to the initial measured result, the power consumption of some wireless modules were increased around 5.5 kGy and the others were increased around 7.2 kGy depending on various control factors while a module of PER was started to decrease around 1 kGy. The tests were performed with various configurations such as distance, frequency, transmitting power, and shielding material at the gamma irradiation facility containing cobalt 60 ? ray with high level activity of 490 kCi in KAERI. The measured data would be useful for researchers not only to find weak parts of the wireless module but also come up with radiation hardening methodologies for a common digital communication system. At the conference, more analyzed and collected data will be shared to discuss which part of the wireless communication system is weak and should be radiation hardened for exploiting specific applications, for example, severe accident monitoring system and unmanned system for nuclear decommissioning.
