Small Reactors without On-site Refuelling: Neutronic Characteristics, Emergency Planning and Development Scenarios
Small reactors without on-site refuelling have a capability to operate without reloading or
shuffling of fuel in their cores for reasonably long periods of time consistent with plant
economy and considerations of energy security, with no fresh or spent fuel being stored at the
site during reactor operation. In 2009, more than 25 design concepts of such reactors were
analyzed or developed in IAEA Member States, representing both developed and developing
countries. Small reactors without on-site refuelling are being developed for several reactor
lines, including water cooled reactors, sodium cooled fast reactors, lead and lead bismuth
cooled reactors, and also include some non-conventional concepts.
To further research and development (R&D) in the areas mentioned above and several others,
and to facilitate progress in Member States in design and technology development for small
reactors without on-site refueling, the IAEA has conducted a dedicated Coordinated Research
Project (CRP) entitled ‘Small Reactors without On-site Refuelling’ (CRPi25001). The project
started late in 2004 and, after a review in 2008, was extended for one more year to be ended in
2009. The project has created a network of 18 research institutions from 10 Member States,
representing both developed and developing countries.
The objective of this report is to document reference points and conclusions achieved through
coordinated research conducted within the CRP on ‘Small Reactors without On-site
Refuelling’ and to suggest R&D activities to be furthered after the CRP completion. Being
documented, the outputs of this CRP may foster further R&D and increase the capability of
Member States to achieve progress in development and deployment of small reactors without
on-site refuelling
