I think we can allow the therapeutic uses of nuclear transplant technology which we call cloning without running the danger of actually having live human beings born.

Nuclear arms and atomic power represent a technology in which coexistence with man is extremely difficult.

U.S. nuclear technology is one of this nation's most valuable secrets and it should have been protected.

I mean when you get down to very low numbers of nuclear weapons and you contemplate going to zero how do you deal with the reality of that technology being available to almost any country that seeks to pursue it? And what conditions do you put in place?

A total nuclear freeze is counterproductive - especially now when technology is rapidly changing and the Soviets have some important strategic advantages.

With a fourth generation of nuclear power you can have a technology that will burn more than 99 percent of the energy in the fuel. It would mean that you don't need to mine uranium for the next thousand years.

I believe that we were not as effective in the second term dealing with this issue of nuclear none proliferation as we had been during the first term when we stripped Libya and Iraq and A.Q. Khan and their capacity to proliferate nuclear technology.

When we're talking about technology that involves weapons of mass destruction nuclear chemical or biological weapons there has to be an element of preemption.

Don't let that weapon technology proliferate. Don't let Saddam Hussein get capability for nuclear or chemical weapons because he's already shown a willingness to use any weapon at his disposal.

Indeed the whole human species is endangered by nuclear weapons or by other means of wholesale destruction which further advances in science are likely to produce.

One thing you can say about nuclear power: the people who believe it is the silver bullet for America's energy problems never give up.

The oil companies regard nuclear power as their rival who will reduce their profits so they put out a lot of disinformation about nuclear power.

This nuclear option is ultimately an example of the arrogance of power.

I have heard that the Saudi Arabians are paying Greenpeace to campaign against Nuclear Power. It wouldn't surprise me at all.

As a nuclear power - as the only nuclear power to have used a nuclear weapon - the United States has a moral responsibility to act.

All the waste in a year from a nuclear power plant can be stored under a desk.

What could become a danger to world peace is Iran's nuclear program and the country's open threat to annihilate Israel.

Several studies and a number of public statements by senior military and political personalities testify that - except for disputes between the present nuclear states - all military conflicts as well as threats to peace can be dealt with using conventional weapons.

I've also gotten to play in front of a million people in Central Park when there was a grass roots movement calling for nuclear disarmament - it was about 1982 - they called it Peace Sunday.

Smiling is very important. If we are not able to smile then the world will not have peace. It is not by going out for a demonstration against nuclear missiles that we can bring about peace. It is with our capacity of smiling breathing and being peace that we can make peace.

When we think of the major threats to our national security the first to come to mind are nuclear proliferation rogue states and global terrorism. But another kind of threat lurks beyond our shores one from nature not humans - an avian flu pandemic.

I can tell you one thing Iran is closer to developing nuclear weapons today than it was a week ago or a month ago or a year ago. It's just moving on with its efforts.

The growth of technology is such that it is not possible today for a nuclear physicist to switch into medical physics without training. The field is now much more technical. More training is needed to do the job.

Let me remind you that nuclear disarmament is not just an ardent desire of the people as expressed in many resolutions of the United Nations. It is a legal commitment by the five official nuclear states entered into when they signed the Non-Proliferation Treaty.
