The IAEA has issued a technical document on the technical basis for the selection of emergency planning zones (EPZ) for small modular reactors (SMRs).

The document is titled: INTERNATIONAL ATOMIC ENERGY AGENCY, Technical Basis for the Emergency Planning Zone for Small Modular Reactors, TECDOC Series - 2134, IAEA, Vienna (2026), https://doi.org/10.61092/iaea.2qab-rn2q.

The document has 132 pages and 11 figures. The language of the document is English.

Information on purchasing a hard copy of the document is available at this link. The current price is 33 euros; the electronic version is available free of charge (see link above).

This IAEA TECDOC is the first IAEA publication to document the results of a coordinated research project (CRP) on emergency planning zones (EPZs) for the deployment of small modular reactors (SMRs).

The publication provides approaches, methodologies and criteria for establishing the technical basis for emergency preparedness and response (EPR) arrangements, with a particular focus on determining the size of EPZs for SMR deployments, based on international safety standards.

This TECDOC reports the formulation of criteria for the events and technical aspects to be considered when defining EPR arrangements for SMRs.

It discusses the implementation of defence in depth in SMR design, as well as the impacts of lower power output, smaller source terms, greater safety margins, engineered safety systems, and smaller and slower releases of fission products, together with the resulting reduced potential for radiation exposure of populations in the vicinity of the plant.

The conclusions on EPZ sizes formulated in the CRP reflect the views of the participating institutes and are based primarily on projected radiological consequences.
