Chennai, Nov 30 (IANS): Each nation can accomplish invincible nuclear security individually and collectively through eternal vigilance, expansion of new energy technologies, coherence, dynamism, self sufficiency among others, said former Indian president A.P.J. Abdul Kalam Tuesday.

"Invincible nuclear security can be accomplished by every nation individually and collectively through eternal vigilance, continuous expansion of new energy technology options, coherence, dynamism and strength, freedom, indestructibility and self sufficiency not only in the immediate term but remain sustainable in the long term for the survival and growth of the human race on planet Earth," Kalam said.

He was presenting his concept paper for the Eminent Persons Group (EPG) chaired by South Korean President Lee Myung-Bak for the 2012 Seoul Nuclear Security Summit.

The paper has been uploaded on Kalam's website.

"Political negotiations, conventions, treaties and the use of arms have not succeeded in creating a long lasting state of world peace and the problem of nuclear insecurity due to terrorism and proliferation may rise again and again at weak moments that humanity invariably passes through, unless all nations achieve invincible security," he said.

"Time demands that the security of every nation should be completely independent of anything outside the nation, but every nation concurrently and generously sharing its special and unique strengths, skills and resources (its core competencies) with other nations in a cooperative, fair and equitable manner," Kalam said.

According to the former Indian president and defence scientist, only such a concept of integrated and balanced independence and interdependence alone can raise the collective invincibility of the human specie.

Kalam said invincible nuclear security in the 21st century can be achieved through sharing of information and intelligence "by real time environmental and situational awareness systems and technologies".

Coherence in formulation and implementation of an international and national nuclear security vision; freedom of every nation to develop evolutionary, creative, democratic socio-economic development process which is not injurious to other nations;indestructibility of society and its critical institutions through creativity and self-sustaining growth using perennial, limitless, sources of clean energy are some of the core principles to be followed for achieving nuclear invincibility by nations, Kalam remarked.

According to him, opting for non-weaponisable thorium route for power generation and nations becoming responsible for nuclear safety and security once they become nuclear power are also important principles.
