Emergency and danger systems - Part 3: Emergency and danger response systems (EDRS) - Risk management file and examples for applications

This document specifies the structure, construction, content and sequence of a technical risk management process and the technical risk management file in accordance with EN 50726-1. It also describes application examples for technical risk management according to EN 50726-1. An emergency and danger response system (EDRS) is used to minimize risks to life and limb. Its purpose is to report, verify and manage emergencies and dangers in order to prevent or limit personal injury. As already mentioned in the scope of application of EN 50726-1, the implementation of the Occupational Safety and Health Act and the subsequent regulations is intended in order to take particular account of the protection objective defined therein (physical integrity). However, this not only includes a risk assessment (e.g. prevention of acts of violence) for employees, but also for everyone in the property. The requirements of the Occupational Safety and Health Act are therefore intended to be observed when creating a safety concept and as part of the technical risk management process. Consequently, particular attention is drawn to paragraphs 5, 6 and 9 of the Occupational Safety and Health Act. Risks to life and limb can include emergencies and dangerous situations that can cause psychological or physical harm to people. As soon as the top management (e.g. operators, entrepreneurs, companies, approving authorities, building authorities, administrations) of a property has identified such risks to life and limb as part of risk management or similar risk assessments and/or independently became aware of them, this falls within the scope of EN 50726-1.

Water quality - Plutonium and neptunium - Test method using ICP-MS (ISO/DIS 20899:2026)

This document specifies methods to determine the 239Pu, 240Pu, 241Pu and 237Np by inductively coupled plasma mass spectrometry (ICP-MS). The mass concentrations obtained can be converted into activity concentrations. Due to its relatively short half-life and 238U isobaric interference, 238Pu can hardly be measured by this method. To quantify 238Pu isotope by mass spectrometry, other techniques can be used (ICP-MS with collision-reaction cell, ICP-MS/MS with collision-reaction cell or chemical separation). Alpha spectrometry measurement, as described in ISO 13167,[8] is currently used[9]. The method is applicable to test samples of supply/drinking water, rainwater, surface and ground water, marine water, as well as cooling water, industrial water, domestic, and industrial wastewater after proper sampling and handling, and test sample preparation. A chemical separation of Np and Pu, with quantitative removal of all other elements (including uranium, americium, etc.) is mandatory, given all the potential interferences that may bias the measurement or lead to false positives. Chemical separations can eliminate most of the 238U. However, use of reagents, glassware, and atmosphere for the chemical separation, will also add 238U to the samples and prevent measurement of 238Pu. The limit of detection depends on the sample volume, the instrument used, the background count rate, the detection efficiency, the counting time, and the chemical yield. The detection limit of the method described in this document, using currently available ICP-MS apparatus, is approximately 1 mBq·l-1 for 239Pu, 240Pu, 237Np and 1 Bq·l-1 for 241Pu, which is lower or of the same order of magnitude than the WHO criteria for safe consumption of drinking water (1 mBq·l-1 for 239Pu, 240Pu, 237Np and 10 Bq·l-1 for 241Pu[4]).This method covers the measurement of those radionuclides in water at activity concentrations between approximately[10][11]: — 1 mBq·l−1 to 5 Bq·l−1 for 239Pu, 240Pu and 237Np; — 1 Bq·l−1 to 5 Bq·l−1 for 241Pu. Samples with higher activity concentrations than 5 Bq·l−1 can be measured if a dilution is performed. The higher is the concentration factor, the lower are the LD and LQ expressed in Bq/L of water. A preconcentration is especially useful for the quantification of 241Pu that is usually the less abundant isotope of plutonium. The method described in this document is applicable in the event of an emergency situation. Filtration of the test sample is necessary. The analysis of 239Pu, 240Pu, 241Pu and 237Np adsorbed to suspended matter is not covered by this method. The analysis of the insoluble fraction requires a mineralization step that is not covered by this document. In this case, the measurement is performed separately on each phase or the total phase. It is the user’s responsibility to ensure the validity of this test method for the water samples tested.

Nuclear energy - Determination of neutron fluence and displacement per atom (dpa) in reactor vessel and internals (ISO/DIS 19226:2026)

ISO 19226:2017 provides a procedure for the evaluation of irradiation data in the region between the reactor core and the inside surface of the containment vessel, through the pressure vessel and the reactor cavity, between the ends of active fuel assemblies, given the neutron source in the core. NOTE These irradiation data could be neutron fluence or displacements per atom (dpa), and Helium production. The evaluation employs both neutron flux computations and measurement data from in-vessel and cavity dosimetry, as appropriate. This document applies to pressurized water reactors (PWRs), boiling water reactors (BWRs), and pressurized heavy water reactors (PHWRs). ISO 19226:2017 also provides a procedure for evaluating neutron damage properties at the reactor pressure vessel and internal components of PWRs, BWRs, and PHWRs. Damage properties are focused on atomic displacement damage caused by direct displacements of atoms due to collisions with neutrons and indirect damage caused by gas production, both of which are strongly dependent on the neutron energy spectrum. Therefore, for a given neutron fluence and neutron energy spectrum, calculations of the total accumulated number of atomic displacements are important data to be used for reactor life management.
