s of 10 CFR 50.34 (10 CFR 52.79). APPENDIX C. MODULAR HIGH-TEMPERATURE GAS-COOLED REACTOR DESIGN CRITERIA Appendix C to DG-1330, Page C-25 VII. Additional mHTGR-DC Criterion mHTGR-DC Title and Content NRC Rationale for Adaptions to GDC 72 Provisions for periodic reactor building inspection. The reactor building shall be designed to permit (1) appropriate periodic inspection of all important structural areas and the depressurization pathway, and (2) an appropriate surveillance program. This newly established criterion on periodic inspection and surveillance provides assurance that the reactor building will perform its safety functions of protecting and maintaining the configuration needed for passive cooling and providing a discharge pathway for helium depressurization events.
