摘要：

The eBlock37 is a subscale electrically heated and heat-pipe-cooled prototype of a fast spectrum microreactor that is under development at Los Alamos National Laboratory. The prototype consists of an electrically heated core and gas-cooled heat exchanger. These subassemblies, both built from 316 L stainless steel, are thermally linked by an array of 37 sodium heat pipes that transfer a nominal 100 kW from the core at 700 degrees C. An overarching objective of this effort is to overcome challenges associated with core block and heat exchanger manufacture and integration of high-temperature heat pipes into the assembly. Components that would be safety critical in an actual reactor, such as the heat pipe wicks, are being built under a Nuclear Quality Assurance 1 quality program. The completed assembly is intended for non-nuclear electrically heated testing, which will be conducted at a demonstration facility at Idaho National Laboratory. This paper provides a top-level summary of the efforts to date.
