in fast breeder reactors.
Safety Analysis, Research and Development AERB continued to promote and fund research

Safety studies were continued in areas covering projects on nuclear safety, radiation safety, front and
severe accident, thermal hydraulics safety, reactor back end fuel cycle safety related problems and industrial
physics, probabilistic safety, radiological assessment safety at academic institutions under the Safety Research
and environmental safety studies and experimental Programme. Four new projects were approved and ten
studies. on-going projects were renewed.
