This International Standard establishes technical requirements and guidelines for the quality assurance of COTS EEE components, ensuring that performance, quality, schedule, cost and other critical requirements are met throughout the entire life cycle of space mission. The family includes electro-optical components. This standard does not cover specific test items for different types of components.

 

This standard specifies the purpose, principle, timing, indicators and process of design and verification for diagnosability and reconfigurability of spacecraft. This standard is applicable to evaluate and design of diagnosability and reconfigurability in the whole life cycle including mainly the stages of ground design and working in-orbit. The evaluation and design of diagnosability and reconfigurability in other stage can also be referred to the implementation. This standard focuses on the subsystem of spacecraft can be reconfigured after a fault occurs, such as attitude and orbit control subsystem, power subsystem and TT&C subsystem.

This document specifies machinery safety requirements. This document is applicable to thermal and catalytic cleaning systems with regenerative or recuperative preheating for exhaust gas loaded with flammable substances from surface treatment equipment. This document deals with all significant hazards, hazardous situations or hazardous events relevant to thermal and catalytic cleaning systems for exhaust gas from surface treatment equipment, when these are used as intended and under conditions of misuse which are reasonably foreseeable. See Annex A for significant hazards. The specific significant risks related to the use of this machinery with exhaust gases from sources other than surface treatment equipment (e.g. from chemical production, tank farms, cremation, wastewater treatment) are not dealt with in this document. Limits of thermal and catalytic cleaning systems for exhaust gas from surface treatment equipment are specified by the interfaces given in Figure 1. Figure 1 - Limits of the machinery This document is not applicable to - cleaning systems without preheating of input gas; - cleaning systems for input gas with a concentration of flammable substances higher than those specified in 4.8; - cleaning systems for input gas containing H2 or pyrolysis gases; - cleaning systems for input gas with a O2/N2 ratio higher than in air; - absorptive and adsorptive exhaust gas cleaning systems; - membrane separators; - UV exhaust gas cleaning systems; - filter systems; - plasma exhaust gas cleaning systems; - biological exhaust gas cleaning systems.

This document specifies an analytical method for determining the neptunium concentration by spectrophotometry, with spectrophotometer implemented in hot cell or glove box allowing the analysis of high activity solutions, with a standard uncertainty, with coverage factor k = 1 of about 5 %, in nitric acid solutions after the dissolution of nuclear reactor irradiated fuels, at different steps of the process in a nuclear fuel reprocessing plant or in other nuclear facilities. The method is applicable to sample from the process containing a concentration of neptunium between 10 mg·l-1 and 400 mg·l-1 and uranium concentrations of up to 300 g·l-1.

 

This document applies to the testing of surfaces that may become contaminated by radioactive materials. The ease of decontamination is a property of a surface and an important criterion for selecting surface materials used in the nuclear industry, interim storage or disposal facilities from which contamination can be removed easily and rapidly without damaging the surface. The test described in this document is a rapid laboratory-based method to compare the ease of decontamination of different surface materials. The results from the test can be one parameter to take into account when selecting surface coatings such as varnish or impervious layers such as ceramics and other surfaces. The radionuclides used in this test are those commonly found in the nuclear industry (137Cs, 134Cs and 60Co) in aqueous form. The test can also be adopted for use with other radionuclides and other chemical forms, depending on the customer requirements, if the solutions are chemically stable and do not corrode the test specimen. The test does not measure the ease of decontamination of the surface materials in practical use, as this depends on the radionuclide(s) present, their chemical form, the duration of exposure to the contaminant and the environmental conditions amongst other factors. The test method is not intended to describe general decontamination procedures or to assess the efficiency of decontamination procedures (see ISO 7503-1 to ISO 7503-3). The test method is not suitable for use of radiochemicals if the radionuclide emits low energy gamma rays or beta particles that are readily attenuated in the surface.

 

This document describes an analytical method for the determination of uranium in samples from pure product materials such as U metal, UO2, UO3, uranyl nitrate hexahydrate, uranium hexafluoride and U3O8 from the nuclear fuel cycle. This procedure is sufficiently accurate and precise to be used for nuclear materials accountability. This method can be used directly for the analysis of most uranium and uranium oxide nuclear reactor fuels, either irradiated or un-irradiated, and of uranium nitrate product solutions. Fission products equivalent to up to 10 % burn-up of heavy atoms do not interfere, and other elements which could cause interference are not normally present in sufficient quantity to affect the result significantly. The method recommends that an aliquot of sample is weighed and that a mass titration is used, in order to obtain improved precision and accuracy. This does not preclude the use of alternative techniques which could give equivalent performance. The use of automatic device(s) in the performance of some critical steps of the method has some advantages, mainly in the case of routine analysis.
