nt of Batteries for Stationary Applications” (Ref. 16), provides helpful ventilation calculations that are associated with IEEE Std. 484. IEEE Std 484-2019 discusses mounting arrangements that allow for inspection of battery cell plates. It is common practice to inspect battery cell plates for conditions that are known to result in DG-1421, Page 6 degradation of battery performance, including excessive accumulation of lead sulfate, growth of the positive plates against the container, and evidence of excessive cell plate corrosion. Consideration of International Standards The International Atomic Energy Agency (IAEA) works with member states and other partners to promote the safe, secure, and peaceful use of nuclear technologies. The IAEA develops Safety Requirements and Safety Guides for protecting people and the environment from harmful effects of ionizing radiation. This system of safety fundamentals, safety requirements, safety guides, and other relevant reports, reflects an international perspective on what constitutes a high level of safety. To inform its development of this RG, the NRC considered IAEA Safety Requirements and Safety Guides pursuant to the Commission’s International Policy Statement (Ref. 17) and Management Directive and Handbook 6.6, “Regulatory Guides” (Ref. 18). The following IAEA Safety Requirements and Guides were considered in the update of the RG: • IAEA Safety Guide NS-G-1.8, “Design of Emergency Power Systems for Nuclear Power Plants,” issued 2004 (Ref. 19) • IAEA Safety Standards Series No. SSG-34, “Design of Electrical Power Systems for Nuclear Power Plants,” issued 2016 (Ref. 20) Although the NRC has an interest in facilitating the harmonization of standards used domestically and internationally, the agency does not specifically endorse the IAEA documents listed above and is only acknowledging that such documents may be a useful reference for general information.
