On the Dimensions Required for a Molten Salt Zero Power Reactor Operating on Chloride Salts
- core criticality and reactivity effects
- neutron flux distribution in space and energy as well as the resulting power distribution
- changes in reactivity and neutron flux resulting from density and temperature changes
- the formation of a team of specialists who are able to develop the project
- the development and production of the first key components, e.g., the fuel
- the establishment of a supply chain
- the close interaction with the regulator to get the experiment licensed 
- Reasonably small core size—reduction of the fuel volume, thus production cost
- Reasonably low enrichment—reduction of fuel production cost, safeguarding concerns, criticality issues in fuel production and handling, but most of all being close to a future iMAGINE system with lower enrichment and/or fissile loading with a correspondingly larger core
- Reasonably low power—avoiding heat extraction while having sufficiently high flux to obtain acceptable measurement time and detector statistics
- Reasonably undisturbed flux distribution—keeping the flux distribution as close as possible to an undisturbed flux distribution of a potential future large scale core
- Reasonable core geometry—avoiding limitations to potential control system approaches due to the core geometry
- Potential operational safety—assure sufficiently strong feedback that the system is self-limiting without heat removal
