核电厂的安全和成功运行取决于设计要求是否能在提供经济有效的功能同时保障工厂人员和公众的安全。ANSI/ANS-57.3-2018 水反应堆核电厂新燃料储存设施的设计要求，解决了与轻水堆核电厂新燃料干燥储存设施所需功能有关的这些问题。该标准规定了相关设备的设计要求，这些设备的功能包括排除危险性; 保障新燃料组件、控制组件、工厂人员和公众的安全; 以及保持低辐射照射。该文件所涵盖的燃料储存设施用于接收、检查和储存含有新的和回收的铀和混合氧化物的燃料。
In an effort to communicate the vital role that standards play in daily life, the American National Standards Institute (ANSI) publishes snapshots of the diverse standards initiatives undertaken in the global and national standards arena, many of which are performed by ANSI members and ANSI-accredited standards developers. Two of the latest selections follow:
Ozone Systems to Treat Water
Ozone systems have been used to treat water for many years because of their ability to eliminate taste and odor problems in addition to other inorganic, organic, and microbiological problems like bacteria and viruses. A new American National Standard (ANS) published by the American Water Works Association (AWWA) describes the minimum requirements for ozone systems and equipment used to treat potable water, wastewater, reclaimed water, and storm water. AWWA F120-2018, Ozone Systems for Water, provides a reference for the design, procurement, installation, and commissioning of ozone systems equipment used in water treatment. The document applies to high concentration ozone generation equipment using discharge dielectrics and modular-type ozone generators fed from oxygen gas vaporized from a liquid oxygen (LOX) storage system. Included in the standard are ozone generators with associated ancillary equipment, fine bubble diffusion and side-stream ozone dissolution systems, and ozone destruct systems including both thermal-catalytic and thermal systems.
AWWA, an ANSI member and accredited standards developer, is the largest professional society for the water supply industry. The organization focuses on total water solutions that assure the effective management of water, offering education to water professionals, advocacy efforts for safe and sustainable water, and volunteer opportunities. Its members include representation from the public and wastewater systems community, environmental advocates, scientists, academicians, and others with a genuine interest in water.
Fuel Storage at Light Water Nuclear Power Plants
The safe and successful operation of nuclear power plants relies on design requirements that assure protection of plant personnel and the public while also providing efficient and economical functionality. ANSI/ANS-57.3-2018,Design Requirements for New Fuel Storage Facilities at Light Water Reactor Plants, addresses these matters in relation to the required functions of dry storage facilities for new fuel at light water reactor nuclear power plants. The standard provides design requirements for the facility that will preclude criticality; assure protection of new fuel assemblies, control components, plant personnel, and the public; and maintain low radiation exposures. Fuel storage facilities covered by the document are used for receiving, inspecting, and storing fuel containing new and recycled uranium and mixed oxides.
This standard was developed by the American Nuclear Society (ANS), an ANSI member and accredited standards developer. ANS is a membership organization of approximately 11,000 engineers, scientists, administrators, and educators that advocates for the advancing and promoting of nuclear science and technology. The organization provides opportunities for professional development, as well as a forum where the nuclear community can share information and advancements in technology.
