PFBR REACTOR

ASSEMBLY

Sectional View of PFBR Reactor Assembly

PFBR is the first of its kind 500 MWe Fast Breeder Reactor in INDIA.

Sodium cooled mixed oxide fuel pool type reactor.

Forerunner of the second stage of the nuclear power program.

Largest and deepest excavated pit in Indian nuclear plants.

First Reactor on common RAFT.

Fabrication and manufacturing of critical NSSS components for the first

time at site by industry with close tolerances.

Salient Features

PFBR- Status of major equipments erection
