ires as assemblies for service in nuclear power plants. The EQ helps ensure that connection assemblies can perform their safety functions during and after a design-basis event (Ref. 21). • RG 1.158, “Qualification of Safety-Related Lead Storage Batteries for Nuclear Power Plants,” describes methods and procedures the staff of the NRC considers acceptable for use in complying with NRC regulations regarding the qualification method of safety-related lead-acid storage batteries for nuclear power plants (Ref. 22). • RG 1.210, “Qualification of Safety-Related Battery Chargers and Inverters for Nuclear Power Plants,” describes a method that the staff of the NRC considers acceptable in complying with the agency’s regulations for the qualification of safety-related battery chargers and inverters for nuclear power plants (Ref. 23). • RG 1.211, “Qualification of Safety-Related Cables and Field Splices for Nuclear Power Plants,” describes a method that the staff of the NRC considers acceptable for complying with the Commission’s regulations for the qualification of safety-related cables and field splices for nuclear power plants (Ref. 24). • RG 1.213, “Qualification of Safety-Related Motor Control Centers for Nuclear Power Plants,” describes a method that the staff of the NRC deems acceptable for complying with the Commission’s regulations for qualification of safety-related motor control centers for nuclear power plants (Ref. 25). Purpose of Regulatory Guides The NRC issues RGs to describe methods that the staff considers acceptable for use in implementing specific parts of the agency’s regulations, to explain techniques that the staff uses in evaluating specific problems or postulated events, and to provide guidance to applicants.
