61 It was he who recommended that the fire be extinguished by dropping sand mixed with boron and lead on to the reactor.

62 The plutonium path Plutonium is a by-product of the controlled fission reaction in a nuclear reactor.

63 Additionally the controversial fast breeder and high temperature reactor projects are being re-examined.

64 The reactor has been redesigned to run on low enriched uranium and its capacity upgraded from 5 to 10 megawatts.

65 There are a number of possible choices for the fuel to be used in a fusion reactor.

66 Chernobyl restart One of the three power plants at the Chernobyl nuclear reactor was restarted on Oct. 16.

67 Although no energy was produced this demonstrated the technical possibility of the process and a serious commercial reactor is envisaged by 2020.

68 But rumour is rife that the reactor pot has already been buried.

69 The plant, an older-style, Soviet-designed pressurised water reactor, has been plagued by problems for several years.

70 The largest proportion - about ￡3.4 billion - had gone on fast reactor research.

71 It claims that operating a reactor at higher temperature, but lower pressure, would strengthen the welds.

72 Perversely, however, wildlife in the area immediately surrounding the Chernobyl reactor appears to be flourishing 14 years after the accident.

73 Operators received lethal doses of radiation while needlessly reconnecting the water supply to the devastated reactor.

74 The dual reactor shutdown commenced on 8 August for essential electrical work.

75 He then entered the reactor compartment and replaced another sailor on the watch.

76 The cooling system broke down, the nuclear reactor overheated, and the plant had to be evacuated.

77 Finally, they were let through an air lock guarded by massive metal doors into the reactor structure.

78 From that point on, the temperature inside the reactor began to rise steadily.

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

80 The plant's operators decided to shut down the reactor and clean the rods.

81 Sometime this year the North will start unloading and replacing spent fuel from a large reactor at Yongbyon.

82 Plutonium is not found naturally on earth, but it is produced whenever uranium is used in a nuclear reactor.

83 Peron gave him Huemmel Island, in a lake in the foothills of the Andes,(www.Sentencedict.com) to build the reactor.

84 One advantage of a rectangular reactor building will be a much simpler overhead crane.

85 The type of accident considered involves the reactor safety features that control the cooling and running of the reactor.

86 The first reactor was closed down for repairs earlier this year after a gas leak.

87 The reactor core erupted in a gigantic explosion, spewing enormous amounts of heat and disintegrated radioactive fuel into the atmosphere.

88 The government attributes this to the improvements in efficiency achieved during the course of the country's intensive reactor building programme.

89 Fresh hydrogen gas is charged to the inlet of the reactor to balance consumption.

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