the mHTGR-DC 16 rationale. 40 Testing of containment heat removal system. Not applicable to mHTGR. This criterion is not applicable to the mHTGR. The mHTGR designs do not have a “pressure retaining reactor containment structure” but instead rely on a multibarrier functional containment configuration to control the release of radionuclides. See the mHTGR-DC 16 rationale. 41 Containment atmosphere cleanup. Not applicable to mHTGR. This criterion is not applicable to the mHTGR. The mHTGR designs do not have a “pressure retaining reactor containment APPENDIX C. MODULAR HIGH-TEMPERATURE GAS-COOLED REACTOR DESIGN CRITERIA Appendix C to DG-1330, Page C-20 IV. Fluid Systems Criterion mHTGR-DC Title and Content NRC Rationale for Adaptions to GDC structure” but instead rely on a multibarrier functional containment configuration to control the release of radionuclides. See the mHTGR-DC 16 rationale. 42 Inspection of containment atmosphere cleanup systems. Not applicable to mHTGR. This criterion is not applicable to the mHTGR. The mHTGR designs do not have a “pressure retaining reactor containment structure” but instead rely on a multibarrier functional containment configuration to control the release of radionuclides.

See the mHTGR-DC 16 rationale. 44 Structural and equipment cooling. In addition to the heat rejection capability of the passive residual heat removal system, systems to transfer heat from structures, systems, and components important to safety to an ultimate heat sink shall be provided, as necessary, to transfer the combined heat load of these structures, systems, and components under normal
