Events prove that, in the context of reprocessing spent nuclear fuel , his prediction is being realised.

Thermal stations burning coal, oil or nuclear fuel work 24 hours a day and their output is less easy to adjust.

Reprocessing is a necessary first step towards recycling nuclear fuel .

Reviving the moribund nuclear industry would be tough and unpopular, and could take many years to produce more power.

In the year 1988/89, £256.8 million went to the nuclear industry , and only £16 million on renewables.

material

But the authoritarian mechanisms that guarded Soviet nuclear material can no longer be guaranteed.

Pentagon officials say they have already had some success reducing the risk that nuclear materials will fall into the wrong hands.

It then swells-for the nuclear material is highly compacted within the sperm-and so becomes a pronucleus.

Storage of nuclear materials is in jeopardy, a government official warned recently.

Each of the two divisions of meiosis produces two daughter cells, each of which contains the same amount of nuclear material .

There have been some real instances of just dumping nuclear material in the oceans.

He says Harwell has now expanded from dealing solely with the field of nuclear physics .

The other simple analogy is to the chain reaction of nuclear physics .

Elena fostered Nicu's interest in nuclear physics .

In 1992/93, after a review of nuclear physics has been completed, it will require £5 million, open or shut.

plant

No, say conservative politicians and industrialists, who are campaigning to save the nuclear plants .

And at the Oyster Creek nuclear plant in southern New Jersey, employees were evacuated by officials who feared an earthquake.

But his environment colleague, Finnin Aerts, wants a moratorium on further nuclear plants .

The first phase of the plan involves expanding its existing solar station beside the closed Rancho Seco nuclear plant this year.

The nuclear plants will not be phased out until the alternative energy sources are ready to come on-stream, however.

What chance did we have at a nuclear plant ?

It has spent scarce resources on its nuclear programme .

The nuclear programme was embarked upon against a background of rising oil and energy prices.

The nuclear programme , because of its sudden appearance and because of the passions it arouses, has encountered its greatest obstacle in people.

The nuclear programme has also mobilised the technical, human, and industrial capacities of an important sector of the economy.

We were committed to the continuance of Britain's nuclear programme .

He called upon the North to close its nuclear reprocessing and enrichment facilities and to submit its nuclear programme to international inspection.

National Power was allocated 70 percent of the power plant, but was given control of the nuclear programme .

proliferation

It has to harry the government to take a less relaxed view on international nuclear proliferation .

Suddenly nuclear proliferation became a high-priority concern in Washington.

Under nuclear proliferation safeguards, plutonium shipments have to be accompanied by armed vessels.

We have to face the fact that there is a bigger risk of nuclear proliferation at present than the world has ever known.

Lugar has devoted most of his ad time and speeches to foreign policy, particularly the threat of nuclear proliferation .

The legislation stated that the plant posed serious environmental hazards and increased the risk of nuclear proliferation .

Britain has always been strongly opposed to nuclear proliferation .

The ship also has facilities to handle nuclear reactor testing and repairs.

Of course, nuclear reactors have superbly efficient back-up systems for just such eventualities.

Devices that are designed to produce stable chain reactions are called nuclear reactors .

There's even a terrifying, bleakly humorous description of the state of Kinshasa's one nuclear reactor .

S.-built nuclear reactor there, the Department of Energy disclosed Wednesday.

More than £20 million in research costs has been lost on an abandoned nuclear safety programme.

submarine

Her earrings and he had to look twice to confirm this-were tiny nuclear submarines , dangling nose up.

The current Polaris nuclear submarine fleet carries 192 nuclear missiles, aimed at the heart of the former Soviet Union.

Several time zones away, a nuclear submarine conducted a surprise test-firing of two long-range ballistic missiles.

An informal probe also showed less serious watch-standing problems on three other nuclear submarines based here.

test

Think small One such should be to lower the limits on the size and frequency of nuclear tests .

Pakistanconducted its first nuclear test days afterward.

Grismore believes high-altitude nuclear tests are the most probable source of the radioactive specks.

The stress echo and nuclear tests are both approximately 85 to 95 percent accurate.

Greenpeace began with a protest voyage into a nuclear test zone.

I hoped she knew to expect that her kitchen would look like a nuclear test site when she returned.

transfer

We produced four live, cloned lambs by nuclear transfer .

The outcome of nuclear transfer can vary a great deal, depending on which of these courses is followed.

There seems to be no a priori reason why nuclear transfer should work.

Conceptually, of course, cloning by embryo splitting is much simpler than cloning by nuclear transfer .

Others did take up Spemann's challenge, and truly began the age of nuclear transfer that he and Loeb had presaged.

warhead

Currently, the Royal Navy is expected to carry 512 nuclear warheads on its Trident fleet.

And nuclear warheads seem to be the weapon or toy of choice for all those involved.

The Citadel was where nuclear warheads were made.

Each tube can hold a Trident missile with up to eight nuclear warheads that can be flung 4, 000 nautical miles.

The proportions of the mix in the Reagan/Brezhnev head are based on the number of nuclear warheads in each leader's arsenal.

The Soviet Union, however, once loaded the missile with a 1-megaton nuclear warhead .

But nuclear power brought nuclear warheads , plastics brought pollution, and the silicon chip promises unemployment for some people.

waste

Containing nuclear waste Anti-nuclear campaigners sometimes claim that nuclear fission and its dangerous products are a purely manmade phenomenon.

Discussions of future reactor safety should revolve about two critical issues: nuclear waste disposal and nuclear weapons proliferation.
