Concern over India's coastal nuclear plans

By Ammu Kannampilly (AFP) – 5 hours ago

NEW DELHI — Japan's struggle to avert a nuclear disaster has led to new calls for a planned huge atomic power plant on the western coast of India to be scrapped.

The proposed Jaitapur station in the state of Maharashtra would be one of the biggest nuclear plants in the world with a total of six reactors providing 9,600 megawatts of power.

Nuclear stations are often built by the sea due to their water consumption, and India -- which aims to supply 25 percent of its electricity from nuclear sources by 2050 -- already has several other nuclear facilities on the coast.

But the Jaitapur programme has attracted large protests from locals and environmentalists who are concerned about the loss of land, the danger of radiation and destruction in the ecologically-sensitive Western Ghats region.

"Japan is an eye opener for us and for the Indian government," Rajeev Betne from the Toxic Links environmental lobby group told AFP. "Local residents in Jaitapur are obviously scared after seeing what's happened in Japan."

A series of protests gathering more than 10,000 people were held at the Jaitapur site last year, with fishermen, farmers and their families refusing to be re-located and complaining about the risk of nuclear pollution.


Anti-nuclear environmental group Greenpeace said Jaitapur, where construction is due to begin in 2013, now had to be scrapped.

"Japan just goes to show that we cannot foresee the worst case scenario and when the technology is inherently dangerous, like nuclear technology, the government needs to be aware of the repercussions," Karuna Raina said.

Indian nuclear experts have moved quickly to issue assurances that the plant would not be vulnerable to an earthquake or tsunami.

"Seismic activity in Japan and India are two different things," former chairman of India's Atomic Energy Commission Anil Kakodkar said on Monday. "I won't say a tsunami will not occur, but its intensity will not be that high.

"Since Jaitapur is on a plateau, the possibility of a tsunami there is low. Though it's along the seashore, it's at a height (of 25 metres, 80 feet)."

Srikumar Banerjee, chairman of the Atomic Energy Commission, emphasised that the plant was crucial to India's future, saying "ours is a very power-hungry country... it is essential for us to have further electricity generation".

India has pushed ahead with its nuclear energy plans since 2008 when then president George W. Bush signed into law a nuclear deal with New Delhi that ended a three-decade ban on US nuclear trade with India.

Since then, France, Russia and private US and Japanese firms have been locked in fierce competition to sell new reactors to India.

French company Areva has signed a 9.3-billion-dollar framework deal to supply the first two of Jaitapur's third-generation pressurised water reactors, with the plant scheduled to begin producing power in 2018.

Bear in mind today's nuclear technology is nothing like as in the same reactor type as the one in Japan, France meets 75% of their energy needs by nuclear fuel.
 
The EPR design has several active and passive protection measures against accidents:

Four independent emergency cooling systems, each capable of cooling down the reactor after shutdown (i.e. 300% redundancy).
Leaktight containment around the reactor.
An extra container and cooling area if a molten core manages to escape the reactor (see containment building).
Two-layer concrete wall with total thickness 2.6 meters, designed to withstand impact by airplanes and internal overpressure.
 
Unless there are safeguards in place, such projects should not be undertaken.

No chance India needs nuclear fuel to meet energy needs dont compare 60 yr old design to new EPR ones India will get

more than the accidents the concern here is shown about ecologically-sensitive location.

Yes there is a risk if a reactor is placed in a coastal zone but that is usually the best place for nuke stations it's a catch 22 situation
 
The Jaitapur station will be so safe that it is said Anything wrong outside cant effect inside & Anything wrong inside cant effect outside
 
So called environmentalists will do their job and govt will do it's. Effective measures have been taken for safeguarding nuclear power stations against any kind of natural and man made threats.

There is a requirement of energy and of that there is no doubt.

Jaitapur region falls in a moderate to high severity earthquake zone as per a government notification.

Bombay is 300 miles to the North.

I am no nuclear physicist nor am I a structural engineer nor an environment activist However, this I understand that one cannot risk the lives of people.

I am yet to hear of that it will be safe. Or that effective measures have been taken for the Jaitapur project.

Jairam Ramesh has raised doubts and the PM has said there has to be a review.

If one was totally sanguine that it was foolproof and safe then the PM and the Minister would not have stated so.
 
These are 3rd gen EPR reactors not old 60yr old designs like the one that exploded in Japan but yes they must meet enviroment safety concerns b4 being implemented
 
Airplane crashes (military jet or large commercial aircraft)
The containment building which houses the most sensitive buildings is particularly robust:

the upper part comprises two walls:
- an inner pre-stressed concrete housing with a steel liner,
- an outer reinforced concrete shell.
the outer shell protects the inner walls and structures from direct impact and resulting vibrations.
This protects the reactor building, the used fuel bilding, two of the four safeguards buildings and the main control room.
The two other safeguards buildings and the diesel buildings are geographically separated, so they cannot both be impacted at the same time.


Earthquakes
To withstand severe earthquakes, the entire nuclear island stands on a single reinforced concrete basemat and the height of the buildings has been minimized.


EPR reactor: safety as a priority - AREVA
 
@Tam Tam -
My hometown is Ratnagiri . I just shifted to Mumbai 2 yrs back
Jaitapur does fall in Zone 4 of Quake .
But there hasnt been any major Earthquake in last 2 decades .
Once there was a minor earthquake and some huts collapsed .

In no way earthquake of range 9.0 can come in Ratnagiri .
As of damage due to Tsunami is nil coz the Jaitapur plant location is on the hill well above the sea lvl .
The 2nd thing is that Japanese nuclear plants were using very old cooling systems .
The plant tht Jaitapur is going to get will be having the latest cooling systems .

The city government , grampanchayat is currently ruled by Congress - Ncp .
So there is almost nil chances tht project is going to be scrapped .
Because of the project many bridges were constructed in tht village and connectivity has increased .
NH 17 is currently being expanded , Ratnagiri's port is being upgraded .
Coz of these project development has alrdy strted .
Except thosr land owners all the other locals r happy
 
European Pressurized Reactor (EPR) also known as Evolutionary Power Reactor is the newest generation of nuclear reactor in the world. It has been designed with many active and passive safety features. Many countries including France, Finland, China, UK, UAE, US, Italy also installing this reactor.
