Non-conventional SMRs

In this report, only one non-conventional SMR concept is presented, which is the AHTR. 

Several output options are provided, ranging from 300 to 1200 MW(e). 

The AHTR is designed as a cogeneration plant to produce electricity and high temperature heat within the range of temperatures from 705 to 1000 °C the heat may be used for hydrogen production or other high temperature process heat applications. 

The AHTR is part of the U.S. DOE Generation IV reactor programme and is being actively investigated. If the AHTR is selected for large-scale deployment, the goal would be to have an operating test reactor by 2012. 

Progress achieved since previous IAEA publications

To support the preparation of this and the previous report [2], an IAEA technical meeting Innovative small and medium sized reactors design features, safety approaches and R D trends was held on 7-11 June 2004 in Vienna, and its final report was published as IAEA-TECDOC-1451 in May 2005 [1]. That TECDOC presented a variety of innovative water cooled, gas cooled, liquid metal cooled and non-conventional SMR designs developed worldwide and examined the technology and infrastructure development needs that are common to several concepts or lines of such reactors. It also introduced the definition of small reactors without on-site refuelling, which is referred to in this report. Both, the technical meeting and the report [1] provided recommendations on the objectives, structure, scope and content of this report and the report [2]. 

This TECDOC presents a variety of innovative water cooled, gas cooled, liquid metal cooled and non-conventional SMR designs developed worldwide and examines the technology and infrastructure development needs that may be common to several concepts or lines of such reactors. The TECDOC also gives an updated definition of small reactors without on-site refuelling and provides a preliminary review of the passive safety design options for SMRs.

Annexes I-XXVI present the contributions from Member States — structured design descriptions of the innovative water cooled, gas cooled, liquid metal cooled and non-conventional SMRs. 

For convenience. Tables ni l through III.9 follow the pattern used in the annexes to this report, i.e., water cooled SMRs appear first, followed by gas cooled, sodium cooled, lead-bismuth cooled and non-conventional SMRs. The order of certain designs within each of the abovementioned groups also follows the sequence used in the annexes, with the corresponding annex number being indicated against each SMR name.
