Nuclear plants in India withstood quake, tsunami: NPCIL

The safety of these BWR plants was reanalysed a few years ago and was reviewed further by Atomic Energy Regulatory Board (AERB).

Following this, the two BWRs at TAPS-1&2 have been renovated, and upgraded with additional safety features to meet the latest safety standards, NPCIL said.

The PHWRs are of different design than BWRs and have multiple, redundant and diverse shutdown systems as well as cooling water systems.

In depth review of events such as quake, Tsunami, etc have been made for all the plants, and necessary reinforcement features based on the outcome of these reviews have been incorporated, it said.

The developments in Japan will be reviewed in detail in the due course, as the detailed information becomes available.

NPCIL is gathering information from various agencies like World Association of Nuclear Operators (WANO), International Atomic Energy Agency (IAEA) and Tokyo Electric Power company (TEPCO) in this regard, the statement added.

Meanwhile, Seismologists here have said earlier that not all Indian reactors are on the coast, and the Indian coastline is more than 2000 km away from Sunda trench where major earthquakes can occur.

As against, Japanese reactors affected by Tsunami are located a few hundred km away from zones that are "highly" prone to quakes.
