“…The spent fuel handling and disposal steps are technically different than for LWR fuels. The bibliography includes three publications (Forsberg 2006;Fuls 2004;Owen 1999) dealing with waste characterization and repository issues associated with this fuel type. Most MHR reactor and fuel concepts are designed for open cycles.…”

A search of trade press and international nuclear publications might yield some useful cost data. -X-Energy in the United States is working on MHR development. They may have done some of their own economic analyses; however, these are likely to be proprietary information. Two U.S. corporations, CENTRUS Corporation (Oak Ridge, TN) and Global Nuclear Fuels (Wilmington, NC), are now partnering with X-Energy on TRISO fuel development in both the United States and Japan (CENTRUS 2017; WNN 2019b; WNN 2020b). -BWX Technologies (or BWXT) of Lynchburg, VA is planning a small production line for TRISO fuel for modular and microreactors intended for defense, aerospace, and special industrial applications. Any cost information is likely to be proprietary (WNN 2019a; WNN 2020a; WNN 2020c; WNN 2020e). -Ultra Safe Nuclear Corp plans to use TRISO-coated particles for its fully ceramic encapsulated fuel. This fuel type has possible application as an accident tolerant fuel for water reactors. Their development center will be located in Salt Lake City, UT (Patel 2021). Again any cost information is likely to be proprietary. -HOLOS-GEN has prepared a TRISO-based fuel cartridge design for a portable microreactor for use by the military in remote locations.

Passive cooling of the PBMR spent and used fuel tanks

The PBMR is a new generation high temperature gas cooled reactor, making use of spherical fuel elements. The spent fuel and partially burnt fuel (called used fuel) is stored in large storage tanks. This paper presents the cooling design of the storage tanks, with special emphasis on its passive cooling ability. For corrosion protection, the tanks are cooled with a closed loop active system, however, passive cooling is seen as the ultimate cooling mode for the storage tanks. If the active cooling fails, the flow automatically bypasses the active system and passive cooling takes over. The active cooling is thus not safety-related; rather its purpose is for investment protection. It has been shown through diverse techniques that the fuel inside the tanks can be cooled passively. There are still a few aspects which need to be explored in more detail, but overall it can be said that passive cooling of the PBMR spent and used fuel in bulk storage tanks is viable.
