One can raise questions when it is about safety of Indian nuclear plants because of recent incident in Tamil Naddu. If you think its propaganda by Pakistan, then you need to read Times of India and Hindustan who reported this news.
On 8th October, 3 Central Industrial Security Force (CISF) personnel shot dead by colleague at Kalpakkam atomic plant in Tamil Nadu. Head constable Vijay Pratap Singh killed his three colleagues. If one incident like this can happen, there are chances of more.
It isn’t the first time that such incident happened in India. There are six major nuclear power accidents that have occurred in India. In 1987, Fast Breeder Test Reactor at Kalpakkam refuelling accident happened that led to its two years shut down. In 1989, Operators at the Tarapur Atomic Power Station find that the reactor had been leaking radioactive iodine at more than 700 times normal levels. Repairs to the reactor took more than a year. In 1992, a malfunctioning tube causes the Tarapur Atomic Power Station to release 12 curies of radioactivity.
In 1993, the Narora Atomic Power Station suffers a fire at two of its steam turbine blades, damaging the heavy water reactor and almost leading to a meltdown. In 1995, Rajasthan Atomic Power Station leaks radioactive helium and heavy water into the Rana Pratap Sagar River, necessitating a two-year shut down for repairs. In 1992, Almost 100 kg radioactive sodium at a fast breeder reactor leaks into a purification cabin, ruining a number of valves and operating systems.
This shows the serious attitude of Indian Government for its atomic energy program. It is question for international community why they are believing and supplying nuclear plants to a country of which nuclear assets are insecure. US and Australia need to revise their nuclear deals with India. Moreover, it raises question on the UN group that is supporting permanent seat of India in UN Security Council.
