Bomb, hydrogen

The use of larger particles in the cyclotron, for example carbon, nitrogen or oxygen ions, enabled elements of several units of atomic number beyond uranium to be synthesised. Einsteinium and fermium were obtained by this method and separated by ion-exchange. and indeed first identified by the appearance of their concentration peaks on the elution graph at the places expected for atomic numbers 99 and 100. The concentrations available when this was done were measured not in gcm but in atoms cm. The same elements became available in greater quantity when the first hydrogen bomb was exploded, when they were found in the fission products. Element 101, mendelevium, was made by a-particle bombardment of einsteinium, and nobelium (102) by fusion of curium and the carbon-13 isotope. 

Tritium is readily produced in nuclear reactors and is used in the production of the hydrogen bomb. 

The fusion of hydrogen into helium provides the energy of the hydrogen bomb. The helium content of the atmosphere is about 1 part in 200,000. While it is present in various radioactive minerals as a decay product, the bulk of the Free World s supply is obtained from wells in Texas, Oklahoma, and Kansas. The only known helium extraction plants, outside the United States, in 1984 were in Eastern Europe (Poland), the USSR, and a few in India.

When hydrogen is proposed as a future fuel, the average person may ask about the Hindcnhurg, the Challenger, or even the hydrogen bomb. Clearly, consumers will not accept hydrogen or any new fuel unless it is as safe as our current fuels. 

In an attempt to develop the hydrogen bomb before the Russians, a second weapons laboratory , Lawrence Livermore, was established in July 1952 to handle the additional work that would be necessaiy to stay ahead of the Russian nuclear weapons program. The administrator chosen was the University of California. Eor the next forty-five years, this LLNL was a formidable competitor to Los Alamos in the development of nuclear weapons. But much like most of the other major national laboratories, its focus also shifted away from nuclear weapons to basic science to fields like magnetic and laser fusion energy, non-nuclear energy, biomedicine, and environmental science. By the late 1990s, half of the laboratoi y s budget was nonde-fense related as the shift away from nuclear weapons continued. 

Inertial confinement fusion has long succeeded in the context of militai y explosions—the hydrogen bomb. In the militai y application a fission bomb produces x-rays that drive an implosion of D-T fuel to enormous temperatures and densities such that fusion reactions occur during the short time that inertia keeps the fusing nuclei densely packed and hot.

Andrei Sakliarov was a Soviet physicist who became, in the words of the Nobel Peace Prize Committee, a spokesman for the conscience of mankind. He made many important contributions to our understanding of plasma physics, particle physics, and cosmology. He also designed nuclear weapons for two decades, becoming the father of the Soviet hydrogen bomb in the Ih.SOs. After recognizing the dangers of nuclear weapons tests, he championed the 1963 U.S.-Soviet test ban treaty and other antinuclear initiatives. 

A hydrogen bomb, which uses nuclear fusion for its destructive power, is three bombs in one. A conventional explosive charge triggers a fission bomb, which in turn triggers a fusion reaction. Such bombs can be considerably more powerful than fission bombs because they can incorporate larger masses of nuclear fuel. In a fission bomb, no component of fissionable material can exceed the critical mass. In fusion, there is no critical mass because fusion begins at a threshold temperature and is independent of the amount of nuclear fuel present. Thus, there is no theoretical limit on how much nuclear fiiel can be squeezed into a fusion bomb.

The Energy Black Hole was the title of my presentation in our conference Topics in Energy and Resources held in January, 1974, in Coral Gables. It was 20 years ago when China had a population of 750 million compared to 1.25 billion in the China of today. The Indian population stood at 600 million, versus one billion now, and in 1974 India hadjust produced its first atomic bomb. Recently, in 1998, both India and Pakistan actually detonated hydrogen bombs, thereby becoming members ofthe nuclearclub. The two countries may now find it easier to talk to each other than when only one of them had the bomb. 

Unstable, silvery metal. The element was first discovered in the fallout from the first hydrogen bomb on the Bikini Atoll (1952), later produced by neutron bombardment of plutonium. Half-lives of the isotopes range from 20 to 401 days. "Relatively short-lived" in comparison to Einstein s formula E=m-c2, which is valid forever. Only of scientific interest. 

Like einsteinium, this unstable element was discovered in the fallout from the first hydrogen bomb. To date, only fragments in microgram amounts can be isolated. 258Fm ends the series of transuranium elements that can be produced in a reactor by neutron bombardment. The longest-lived isotope decays with a half-life of 100 days...

B. Benzophenone hydrazone. A hydrogenation bomb is charged with 25.2 g. (0.138 mole) of benzophenone, 7.46 g. (0.23 mole) of anhydrous hydrazine, and 14 ml. of absolute alcohol. The bomb is closed with a safety head instead of the usual pressure gauge assembly and is then heated for 4 hours at 150°. After the bomb has cooled, it is opened and the benzophenone hydrazone is removed from the mixture. It weighs 26.4 g. and melts at 94-99°. After recrystallization from 75 ml. of 95% alcohol, the hydrazone forms long white needles which melt at 97-98° and weigh 21.5-22.0 g. (80-82%).

To a solution of 197 g. (1 mole) of bromoacetal1 in 250 ml. of absolute alcohol, cooled in a hydrogenation bomb of about 1.1-1. capacity to the temperature of a Dry Ice-acetone bath, is added approximately 300 g. (about 18 moles) of liquid ammonia (Note 1). The bomb is closed, connected with a pressure gauge, and heated at 120-130° with shaking for 12 hours. The pressure rises to about 2300 pounds.
