These sources tend to be much weaker than reactors.

These are much smaller than power reactors or those propelling ships, and many are on university campuses.

:: These reactors use a pressure vessel to contain the nuclear fuel, control rods, moderator, and coolant.

These reactors are fueled with natural uranium and are thermal neutron reactor designs.

These reactors can function much like a PWR in terms of efficiency, and do not require much high pressure containment, as the liquid metal does not need to be kept at high pressure, even at very high temperatures.

These reactors are fast neutron, not thermal neutron designs.

These reactors come in two types:

:: These reactors use soluble nuclear salts dissolved in water and mixed with a coolant and a neutron moderator.

These natural reactors are extensively studied by scientists interested in geologic radioactive waste disposal.

These isotopes are formed in nuclear reactors.

These isotopes are difficult to separate, and more cost-effective ways of obtaining fissile material exist ( e. g. uranium enrichment or dedicated plutonium production reactors ).

These reactors were boron-doped vertically for longer core life, and axially for even power distribution without hot spots.

These are mainly processes in the chemical industry, the interior of reactors or facilities for manufacture of nuclear fuel.

These are fast-neutron reactors.

These are the second generation of British gas-cooled reactors, using graphite as the neutron moderator and carbon dioxide as coolant.

These four regions oversee the operation of 104 power-producing reactors, and 36 non-power-producing reactors.

These " Annex 2 States " participated in the negotiations on the CTBT between 1994 and 1996 and possessed nuclear power or research reactors at that time.

These small reactors were used primarily for testing the behaviour of different materials under intense neutron irradiation to help decide what materials to build reactor components out of.

These models can also be used in the design or modification of chemical reactors to optimize product yield, more efficiently separate products, and eliminate environmentally harmful by-products.

These were carbon dioxide-cooled, graphite reactors with natural uranium metal fuel, very similar in design and purpose to the British Magnox reactors except that the fuel cladding was magnesium-zirconium alloy.

These nuclear fission pressurized water reactors ( PWRs ) were jointly designed by Bettis Atomic Power Laboratory and Knolls Atomic Power Laboratory

These reactors were also required for the production of polonium-210 by irradiation of bismuth-209, which was used in the modulated neutron initiators, a critical component of the nuclear weapons.

These reactors may be a valuable tool in the hands of an experienced chemist or reaction engineer:

These were the ones Keith sought out -- the loners, the ones who killed for the joy of it, like himself.

These were the last words he ever uttered.

These two were going to be easy pickins.

These performances were being staged at historical monuments throughout Europe.

These were Oneida Indians.

These conceptions and the manner in which they were transposed into poetry or engendered by poetic form are intrinsic to western life from the time of Aeschylus to that of Shakespeare.

These basic ideas concerning the nature of religion were, Adams believed, some of the major keys to the understanding of history and the movement of society.

These were his public academic activities, domi forisque, in the college and in the university.

These early experiments were evidently not altogether satisfying to Patchen.

These people were not talking much about it, but you, a foreigner, sensed their apprehension and disappointment.

These public efforts were rare because Mr. Rayburn normally did his counseling, persuading and educating long before an issue reached its test on the House floor.

These microfossils indicate the swamp was `` formed during the Lower Cretaceous period when dinosaurs were at their heyday and when the first flowering plants were just appearing.

These were heroes nine feet tall to him ''.

These little songs, however, were sweet nothings from the heart, tender memories of his childhood, little melodies that anyone could hum and that would make one want to weep.

These were the ships of His Majesty's Navy, herding the hulks of the East Indies merchants and the yachts and ketches of the loyalists.

These trumps were more touching than they were anything else, and seemed to imply that the nights were long, her children ungrateful, and her marriage bewilderingly threadbare.

These were selected carefully and included not only detailed clinical information but adequate pathology of value for research and educational purposes.

These amendments to the Vocational Rehabilitation Act were designed to help provide for more specialized rehabilitation facilities, for more sheltered and `` half-way '' workshops, for greater numbers of adequately trained personnel, for more comprehensive services to individuals ( particularly to the homebound and the blind ), and for other administrative improvements to increase the program's overall effectiveness.

These plans, like Du Pont's, contained provisions for passing the vote on Du Pont's General Motors shares on to the ultimate stockholders of Du Pont, Christiana, and Delaware, except that officers and directors of the three companies, their spouses, and other people living in their households, as well as other specified persons, were to be totally disenfranchised.

These curves were derived by an analysis of extensive skywave measurement data.

These were educated men, who, as Mr. Justice Holmes was fond of saying, formed their inductions out of experience under the burden of responsibility.

These boys acknowledged an introduction to anybody by gently pressing one of his hands in both of theirs, while they gazed, misty-eyed with care, into the eyes of the person they were meeting.
