This document covers the functional recommendations for the design, construction, testing, commissioning, operation, maintenance and abandonment of the surface facilities for underground gas storage (UGS), between the wellhead and the connection to the gas grid. It specifies practices which are safe and environmentally acceptable. For necessary subsurface facilities for underground storage, the relevant part of EN 1918 1 to EN 1918 4 applies. In this context, “gas” refers to flammable gas: — which is in a gaseous state at a temperature of 15 °C and under a pressure of 0,1 MPa. The stored product is also named fluid. — which meets specific quality requirements in order to maintain underground storage integrity, performance, environmental compatibility and fulfils contractual requirements. This comprises: — gas not in liquid phase under subsurface conditions: — methane-rich gases; — natural gas; — biomethane; — synthetic methane; — hydrogen of various purities; — any mixtures of the gases above; — hydrocarbon gas in liquid phase under subsurface conditions such as: — ethylene; — liquified petroleum gas (LPG). NOTE 1 Correspondingly the EN 1918 series can be considered where applicable for underground storage of any other fluid e.g. helium, carbon dioxide, compressed air, rDME (renewable dimethyl ether) and hydrogen transport fluids (such as ammonia and LOHC). This document is not intended to be applied retrospectively to existing facilities. NOTE 2 Correspondingly this document can be considered for major conversions in case of significant change of gas composition.

Nuclear energy - Reference beta-particle radiation - Part 3: Calibration of area and personal dosemeters and the determination of their response as a function of beta radiation energy and angle of incidence (ISO 6980-3:2023)

This document describes procedures for calibrating and determining the response of dosemeters and dose-rate meters in terms of the operational quantities for radiation protection purposes defined by the International Commission on Radiation Units and Measurements (ICRU). However, as noted in ICRU 56, the ambient dose equivalent, H*(10), used for area monitoring, and the personal dose equivalent, Hp(10), as used for individual monitoring, of strongly penetrating radiation, are not appropriate quantities for any beta radiation, even that which penetrates 10 mm of tissue (Emax > 2 MeV). This document is a guide for those who calibrate protection-level dosemeters and dose-rate meters with beta-reference radiation and determine their response as a function of beta-particle energy and angle of incidence. Such measurements can represent part of a type test during the course of which the effect of other influence quantities on the response is examined. This document does not cover the in-situ calibration of fixed, installed area dosemeters. The term “dosemeter” is used as a generic term denoting any dose or dose-rate meter for individual or area monitoring. In addition to the description of calibration procedures, this document includes recommendations for appropriate phantoms and the way to determine appropriate conversion coefficients. Guidance is provided on the statement of measurement uncertainties and the preparation of calibration records and certificates.
