​One of the important design goals for the Fort St. Vrain reactor – really, the second-generation high temperature gas cooled reactor – was to create a core design that would be more compact than that actually used at Peach Bottom.  An innovative design was developed using stacked reactor-grade graphite modular blocks which incorporated fuel rods that contained coated fuel particles. Read more

​The Fort St. Vrain project was innovative in more than one respect, and while it did not blaze the trail in HTGR (High Temperature Gas-cooled Reactor) commercialization – a feat accomplished by the Peach Bottom Atomic Power Station – it did considerably advance the technology toward full commercial operation and duplication on a wide scale through some significant design changes.  One of the most interesting of these was the use of a prestressed concrete reactor vessel (PCRV) for the reactor itself and primary components instead of a steel vessel.
