d to qualify them against loss of ductility in cold temperatures; therefore, the guidance in Regulatory Position 5 is recommended. Regulatory Position 6 CC-2438.4: Permanent Coating Material Permanent corrosion prevention coating applied to the tendons is important to protect against corrosion degradation and maintain the structural integrity of tendons as a load-bearing component. Regulatory Position 6 addresses the certification of test data verifying properties, qualification test data, and test reporting specified in subparagraph CC-2438.4 that is provided by the coating manufacturer for the permanent coating material. Regulatory Position 7 CC-2463: Type and Number of Performance Tests Various prestressing systems may require different numbers of tests for tendon systems to establish their adequacy for qualification and use. Variations within the tolerance limits of the construction specification for material properties and geometry of anchorages and tendons need to be realistically and adequately represented in the system testing. This is addressed in Regulatory Position 7. Regulatory Position 8 CC-3000: DESIGN To facilitate design and analysis procedures, some specific guidance in addition to the Code specification are included in Regulatory Positions 8.a through 8.e to be consistent with the current staff position. That is, this RG includes additional load considerations and loading combination guidelines for the design and analysis of concrete containments. Regulatory Position 8.a(1) with regard to hydrodynamic loads resulting from LOCA or safety/relief valve (SRV) actuation for boiling-water reactor containments is the same as that in Appendix A to NUREG-0800, Section 3.8.1. To address the requirements of 10 CFR 50.34(f) and 10 CFR 50.44(b) and (c), concerning the demonstration of containment structural integrity for accidents involving hydrogen release and combustible gas release, Regulatory Position 8.b provides loads and load combinations for pressure
