This part of EN 16905 specifies the calculation of the seasonal performance factor for gas-fired endothermic engine driven heat pumps for heating and/or cooling mode including the engine heat recovery, to be used outdoors. This document only applies to appliances with a maximum heat input (based on net calorific value) not exceeding 70 kW at standard rating conditions. This document only applies to appliances under categories I2H, I2E, I2Er, I2R, I2E(S)B, I2L, I2LL, I2ELL, I2E(R)B, I2ESi, I2E(R), I3P, I3B, I3B/P, II2H3+, II2Er3+, II2H3B/P, II2L3B/P, II2E3B/P, II2ELL3B/P, II2L3P, II2H3P, II2E3P and II2Er3P according to EN 437. This document only applies to appliances having: a) gas fired endothermic engines under the control of fully automatic control systems; b) closed system refrigerant circuits in which the refrigerant does not come into direct contact with the fluid to be cooled or heated; c) where the temperature of the heat transfer fluid of the heating system (heating water circuit) does not exceed 105 °C during normal operation; d) where the maximum operating pressure in the: 1) heating water circuit (if installed) does not exceed 6 bar, 2) domestic hot water circuit (if installed) does not exceed 10 bar. This document applies to GEHP appliances only when used for space heating or space cooling or for refrigeration, with or without heat recovery. This document is applicable to GEHP appliances that are intended to be type tested. Requirements for GEHP appliances that are not type tested would need to be subject to further consideration.

This document provides guidance on specific requirements for each stage of the low and intermediate-level radioactive waste management life cycle (prior to disposal), activities and services to implement these requirements, and outcomes (e.g., data, records, reports).

This document specifies a test method for low temperature mechanical properties of electrical insulation materials of superconducting magnets made from cable-in-conduit with stainless steel jacket for application.

The important superconducting magnets mainly include magnetic confinement fusion experimental devices and other magnet confinement fusion devices. The main insulation materials include glass fibres, polyimide films and resin systems. The main mechanical properties include tensile strength, shear strength, compression shear stress, push-out strength and the strength after fatigue.

The document provides:

— guidelines for determining the thermal effects to consider on fire barriers inside a given room;

— guidelines for determining the global performance of the fire barriers based on standard test characterization;

— guidelines for assessing the need for additional tests to verify the robustness of the solution.

Requirements of applicable standards, numerical tools validation and verification (V&V), and the expected qualification of fire resistance laboratories are detailed.

The limitations of the method's applicability and scope are discussed.

The purpose and justification of this document is to describe a new methodology for the verification of the efficiency of fire barriers, which is initially based on a standardized fire resistance test.

The significance of this work relates to the fact that the present methodology will enhance the level of safety by providing more realism to hazards analysis in combination with standardized test data. It completes the standard ISO-fire rating required for justifying the performance.

The most relevant benefit of this method concerns the determination of the global performance of a barrier in a fire of extended duration compared to the classification given by the ISO-fire rating.

This document establishes the organizational, design, construction, operational, and quality-assurance requirements applicable to heterogeneous, thermal-spectrum research reactors with power levels up to several tens of megawatts. It defines the minimum expectations for management structure, project governance, safety culture, quality assurance, documentation control, and lifecycle oversight necessary to

ensure safe, compliant, and effective reactor operation.

The document applies to new research reactors and, where practicable, to existing or legacy reactors using a graded approach consistent with IAEA SSR-3[6] a nd I AEA S SG-22.[10] It addresses administrative and operational controls, procurement and inspection processes, training and qualification, radiation protection, and change management throughout the reactor lifecycle, including modifications and decommissioning.

This document does not prescribe detailed technical design specifications; rather, it provides the framework within which such specifications are developed, reviewed, and controlled. Additional guidance may be required for reactors exceeding the stated power range or for specialized reactor types such as fast spectrum systems or facilities incorporating advanced experimental features.
