`Back-up` measures proposed to enhance nuke safety

Mumbai: A high-level committee, appointed by
the Atomic Energy Regulatory Board (AERB) in the aftermath of
the Fukushima incident, has expressed satisfaction over
prevailing measures for safeguarding nuclear reactors, even as
it proposed "back-up" steps to raise the safety level.

"We have submitted our report to the AERB this weekend
and most of the safety features with the Indian nuclear plants
are satisfactory but still we have suggested for back-up
safety features as a matter of abundant caution," Nuclear
Safety Review Committee (NSRC) chairman S K Sharma said.

"We have suggested back-up provisions to feed water for
reactor steam generator and coolants and for Tarapur Atomic
Power Plants units 1 and 2, which are boiling water reactors
almost similar to Fukushima reactors. We have suggested back
up water to the emergency condenser for ensuring uninterrupted
cooling of the reactor in case of a station blackout," Sharma
said.

The NSRC has proposed setting up an emergency facility at
each of the nuclear reactor sites as one of the measures. The
facility would comprise of a separate building with provisions
for continuous communication, feeding, rest room for engineers
and others who are on emergency duty, he said.

Another suggestion of the Committee includes a provision
for setting up additional air-cooling generators and portable
generators to overcome station blackout in case of an accident
like that of Fukushima Daiichi nuclear power plants in Japan,
which were hit severely by a major earthquake followed by an
unprecedented tsunami on March 11 this year.

On the assessment experience, Sharma said Indian nuclear
industry and AERB always carry out safety review following any
incident/accident reported in the world. Post Fukushima is one
such exercise and the Committee suggested few steps to the
Board, he said.
