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.

NRC restores expiration dates for renewed Turkey Point licenses
The Nuclear Regulatory Commission announced this week that it has restored the expiration dates of the Turkey Point nuclear power plant's units 3 and 4 subsequent license renewals (SLR) to July 19, 2052, and April 10, 2053, respectively.

The nuclear industry desires to implement wireless technology to improve communication efficiency, optimize maintenance, improve security, and add to plant safety and availability. Examples of wireless applications which are being targeted by nuclear power plants for efficiency gains are: 1) tablet based work orders and calibration procedures, 2) wireless access to plant engineering documentation, 3) voice communication anywhere in the plant, 4) temporary or permanent installation of wireless cameras, and 5) equipment condition monitoring using wireless sensors. Prior to implementation, nuclear power plants must resolve the electromagnetic and radio frequency (EMI/RFI) challenges for wireless devices to prevent interference with sensitive plant equipment. Traditionally, nuclear facilities have defined specific or generic exclusion zones where wireless devices cannot be used. In most cases, this has caused plants to prohibit the use of wireless devices in some entire rooms of the plant. Research performed by AMS determined that exclusion distances in almost all nuclear power plants are still overly conservative and thereby severely limit the use of wireless devices in many areas of the plant. Most of these exclusion distances are much larger than necessary and can be significantly reduced by using in-situ EMI/RFI testing techniques. The Krško nuclear power plant in Slovenia is evaluating the use of Wi-Fi devices to support plant operators in performing their daily rounds and other maintenance activities, including within the Main Control Room (MCR). The exclusion distances calculated for Wi-Fi devices would prevent them from being used within the MCR. For this reason, and because a majority of the older equipment did not have documented evidence of Electromagnetic Compatibility (EMC) qualification testing, Krško personnel chose to perform in-situ EMI/RFI testing of equipment throughout the plant including within the MCR. This paper will outline the project objectives, test methodologies, challenges that were encountered, and results of the testing activities.
