UIUC submits MMR construction permit application
The University of Illinois–Urbana-Champaign, in partnership with Nano Nuclear Energy, has submitted a construction permit application to the Nuclear Regulatory Commission for construction of a Kronos micro modular reactor (MMR). This is the first major step in the two-part 10 CFR Part 50 licensing process for the research and test reactor and is the culmination of years of technical refinement and regulatory alignment.
The team chose to engage with the NRC in a preapplication readiness assessment, providing the agency with draft versions of the majority of the CPA’s technical content for feedback, which is expected to ensure a high-quality application.

The interfacial strength of SiC/SiC composites fabricated by hot-pressing (HP) and chemical vapor infiltration (CVI) method was measured by push-in test, and the effect of interfacial strength on the fracture behavior of SiC/SiC composites was investigated. Maximum strength and fracture energy of the CVI-SiC/SiC composite was higher than those of the HP-SiC/SiC composite due to lower interfacial shear sliding strength and higher fiber strength. The SiC/SiC composite hot-pressed at 1750 °C had a higher interfacial shear sliding strength and lower fiber strength, resulting in low maximum strength and fracture energy. The SiC/SiC composite hot-pressed at 1650 °C showed a lower maximum strength and higher fracture energy in spite of a lower interfacial shear sliding strength and higher fiber strength. In this case, the delamination between fiber and the matrix occurs easily.
