ISO/TC 85/SC 6/WG 2 - Research, test and isotope-production reactors
To develop, maintain and promote standards for the design, construction, operation, maintenance, utilization, and decommissioning of research and test reactors. For the forthcoming years, priority will be given to operation, maintenance, utilization including refurbishment issues, dosimetry for research reactors services, and production of isotopes for nuclear medicine.
Réacteurs de recherche, d'essais et de production d'isotopes
Elaboration, maintenance et promotion des normes applicables à la conception, à la construction, à l’exploitation, à la maintenance, à l’utilisation et au déclassement des réacteurs de recherche et d’essai. Pour les années à venir, la priorité sera donnée à l’exploitation, à la maintenance, à l’utilisation y compris les questions liées à la rénovation, à la dosimétrie pour les réacteurs de recherche services et à la production d’isotopes pour la médecine nucléaire.

The International Organization for Standardization (ISO) is an independent, non-governmental international organization that develops and publishes international standards. Founded in 1947 and headquartered in Geneva, Switzerland, ISO brings together experts from 170+ member countries to share knowledge and develop voluntary, consensus-based standards that support innovation and provide solutions to global challenges.
A Subcommittee (SC) in ISO operates under a Technical Committee and focuses on a specific subset of the TC's scope. Subcommittees develop standards and technical specifications in their specialized area, reporting to their parent Technical Committee. They may also have working groups for detailed technical work.
This document specifies the methods and techniques for leak tightness assessment of a metallic component at high temperature by measuring its total leakage rates in a vacuum chamber with a tracer gas leak detector and high-pressure helium gas or the gas mixture flowing out of the component as tracer gas during its thermal and pressure cycles at its operating conditions. The minimum detectable leakage rate can be as low as 10-10 Pa·m3/s, depending on the dimension, external configuration complexity and materials of the component, and is strongly related to the test system and the test conditions. This document is applicable for the hot helium leak test of in-vessel components as per its normal operating conditions in nuclear fusion reactors, which operate at elevated temperatures in an ultra-high vacuum environment down to 10-6 Pa and with inner flowing-coolant at operating pressure. It is also applicable to the overall leak tightness test of welds in other metallic components and equipment that could be evacuated and pressurized, such as pressurized tanks, pipes and valves in power plants, aerospace and other nuclear reactors.
