AECS Research Reactor (RR) Types Miniature neutron source reactor - PowerPoint PPT Presentation

AECS

Research Reactor (RR) Types • Miniature neutron source reactor (MNSR) of 30kW to about 100MW(t) RR (1–10 MW more common) • Industrial manufacturer supplied RR to custom­built indigenous RR • Neutron flux ranging from 10 11 to 10 14 – Neutron beam facilities – Sample irradiation facilities (radioisotope production, material testing) – Rabbit facility for NAA – Analytical and other services facilities AECS
