stead rely on a multibarrier functional containment configuration to control the release of radionuclides. See the mHTGR-DC 16 rationale. APPENDIX C. MODULAR HIGH-TEMPERATURE GAS-COOLED REACTOR DESIGN CRITERIA Appendix C to DG-1330, Page C-22 V. Reactor Containment Criterion mHTGR-DC Title and Content NRC Rationale for Adaptions to GDC 51 Fracture prevention of containment pressure boundary. 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. 52 Capability for containment leakage rate testing. 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. 53 Provisions for containment testing and inspection. 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. 54 Piping systems penetrating containment. 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. 55 Reactor coolant boundary penetrating containment. 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
