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.

Vogtle-3 shuts down for valve issue
One of the new Vogtle units in Georgia was shut down unexpectedly on Monday last week for a valve issue that has since been investigated and repaired. According to multiple local news outlets, Georgia Power reported on July 17 that Unit 3 was back in service.
Southern Company spokesperson Jacob Hawkins confirmed that Vogtle-3 went off line at 9:25 p.m. local time on July 8 “due to lowering water levels in the steam generators caused by a valve issue on one of the three main feedwater pumps.”

This paper describes the configuration management process using classified Computer Code. Hardware can confirm the configuration visually, but it is not only difficult for the software to show its integrity or errors, but also hard for developers or user to determine the overall configuration. Due to the properties of the software, it is essential for the entire configuration to be identified and to verify the quality requirement management. Therefore, for the software being developed to be used, configuration management must be handled at the highest level and each software component requires configuration control at its lower level. Computer codes are package software that is used as a tool for design, development, and licensing in the nuclear industry. In general, computer codes are divided into computer design codes, computer analysis codes, and regulatory computer codes. Software includes computer code, which is embedded software that is mounted as part of the hardware system, and supported software being used for additional computer code. The newly developed computer code must be subject to management, analysis, development, coding, testing, installation, operation and maintenance, and retirement phase according to the quality assurance requirements. In this paper, the kind of computer code describes its assignment in the developing of the computer code process and changing of the computer code process. According to the classification, codes were divided into three categories of SW Life Cycle, Combined Cycle, and Simplified Cycle. Depending on the classification, we have three different tick issue classes among the software life cycle. We propose a method of configuration management to manage the quality data of computer codes in a comprehensive manner in an interface.
