New reactor orders were virtually non-existent. ► nuclear· Its flies, the spent fuel, arrive regularly inside special containers on goods trains from nuclear reactors all over the country.· The nuclear reactor which propels the submarine was not damaged, he added.· The ship also has facilities to handle nuclear reactor testing and repairs.· In Britain at least we have spent two decades arguing about what type of nuclear reactor to build.· Over the same period, research on advanced nuclear reactors will be eliminated and one of the two uranium enrichment plants closed.· Where perfect quality is required, for example in the construction of nuclear reactor plant, then 100% inspection will be applied.· Whether this concern can prevent another Chernobyl-type nuclear reactor disaster remains to be seen. ► old· Astonishingly, several old Chernobyl-type reactors are still in service, despite their well-known design defects. ► pressurised· The plant, an older-style, Soviet-designed pressurised water reactor, has been plagued by problems for several years. NOUN► accident· Recent reactor accidents have caused a marked slowdown in the installation of nuclear power stations.· The tightening up of safety standards at nuclear power plants inevitably followed the reactor accidents. ► breeder· For energy, the winners are physics, fusion and the breeder reactor.· But the technology that makes power reactors possible also makes breeder reactors feasible.· The largest fast breeder reactor in the world is the Superphenix plant at Creys-Malville on the French/Swiss border.· To get the most out of the mined uranium and thorium, they must be cycled through breeder reactors.· More recently, the demand for fast breeder reactors has seemed less urgent as worldwide supplies of uranium have become more plentiful.· We would also have to discuss the development of fast breeder reactors, a necessity for all countries with limited uranium resources.· Protests reached their peak in 1977 with the decision to build the 1200 MWe fast breeder reactor at Creys-Malville. ► building· The government attributes this to the improvements in efficiency achieved during the course of the country's intensive reactor building programme.· Inside the plant, levels of radiation in the abandoned reactor building rose to many times the lethal level.· One advantage of a rectangular reactor building will be a much simpler overhead crane. ► core· To protect power station workers from this invisible threat the reactor core has to be encased behind many metres of thick concrete.· Radioactivity is induced in the metallic containment vessel that surrounds a reactor core by neutrons that escape from the core.· During the last 30 years there have been 12 accidents around the world that have caused serious damage to a reactor core.· The accident, which occurred on August 13, did not involve the release of radiation or damage to the reactor core.· Leaks in primary circuits distributing heat from the reactor core would be uncontrollable, leading to a core meltdown.· The reactor core erupted in a gigantic explosion, spewing enormous amounts of heat and disintegrated radioactive fuel into the atmosphere. ► fuel· Since Pu acts like U, the end result is quite like the low-enriched uranium used as reactor fuel.· It is clear that steps must be taken to prevent reactor disposal of this material from stimulating reprocessing of commercial reactor fuel. ► fusion· They will also have developed a new technique for controlling reactions within a fusion reactor.· The use of light isotopes in a fusion reactor has been under experimental study since the 1950s.· The reactor is widely regarded as the last step before design of commercial fusion reactors.· They include a laboratory for handling tritium, the heavy radioactive isotope of hydrogen which is a fuel for fusion reactors.· There are a number of possible choices for the fuel to be used in a fusion reactor.· Now that there is every reason to believe that we can build a fusion reactor there is growing attention to technology.· The first is the need to demonstrate operation well above the break-even point in a fusion reactor. ► magnox· They were particularly important for the Magnox reactors, which used larger quantities of fuel and had bulkier structures to dismantle.· The company is also planning to expand the life of the existing Magnox reactors by another 10 years.· Reprocessing is becoming an increasingly costly item in the fuel cycle of Britain's ageing Magnox reactors.· The Magnox reactor has been shut since February.· As well as generating electricity, Magnox reactors are particularly efficient at producing plutonium.· As we shall see later, the economic performance of the Magnox reactors has also come under increasing scrutiny. ► power· Some would argue that while nuclear power reactors exist, then a repetition is inevitable.· But the technology that makes power reactors possible also makes breeder reactors feasible. ► research· In other words, Dounreay has agreed to store the spent fuel from research reactors for four years.· Until recently, even the total number of research reactors in the country was unknown.· It would like to export research reactors to other countries, says Iyengar. ► safety· The type of accident considered involves the reactor safety features that control the cooling and running of the reactor.· Discussions of future reactor safety should revolve about two critical issues: nuclear waste disposal and nuclear weapons proliferation. ► site· In addition, at least one little owl has been raised on reactor site. ► water· The plant affected, a 500,000 kilowatt pressurized light water reactor, began operation in 1972.· Objectors at the Sizewell pressurised water reactor inquiry will make this very point.· The plant, an older-style, Soviet-designed pressurised water reactor, has been plagued by problems for several years. VERB► build· Peron gave him Huemmel Island, in a lake in the foothills of the Andes, to build the reactor.· Now that there is every reason to believe that we can build a fusion reactor there is growing attention to technology.· S.-built nuclear reactor there, the Department of Energy disclosed Wednesday. ► shut· It commits the industry to shut down its 19 reactors after an average running time of 32 years.· The plant's operators decided to shut down the reactor and clean the rods. ► use· Such adsorption may be a problem when using above-ground reactors.· At the same time, they would work with us on the direct disposal of this material without using reactors.· Indigenous microorganisms are now used in above-ground batch reactors, but commercial blends are being used to degrade petroleum hydrocarbons.· The penalty for using a reactor is that we must carry the weight of the reactor and its associated radiation shielding.· Plutonium is not found naturally on earth, but it is produced whenever uranium is used in a nuclear reactor.· But if we are using the reactor on unmanned missions only, the mass of shielding required may be very small.· There are a number of possible choices for the fuel to be used in a fusion reactor.
