Uranium-233 is a fissile isotope of uranium, bred from thorium-232 as part of the thorium fuel cycle. Uranium-233 was investigated as a reactor fuel, it has been used in experimental nuclear reactors and has been proposed for much wider use as a nuclear fuel. It has a half-life of 160,000 years. Uranium-233 is produced by the neutron irradiation of thorium-232; when thorium-232 absorbs a neutron, it becomes thorium-233, which has a half-life of only 22 minutes. Thorium-233 decays into protactinium-233 through beta decay. Protactinium-233 has a half-life of 27 days and beta decays into uranium-233. 233U fissions on neutron absorption, but sometimes retains the neutron, becoming uranium-234. The capture-to-fission ratio of uranium-233 is smaller than those of the other two major fissile fuels, uranium-235 and plutonium-239. In 1946, the public first became informed of uranium-233 bred from thorium as "a third available source of nuclear energy and atom bombs", following a United Nations report and a speech by Glenn T. Seaborg.

The United States produced, over the course of the Cold War 2 metric tons of uranium-233, in varying levels of chemical and isotopic purity. These were produced at the Hanford Site and Savannah River Site in reactors that were designed for the production of plutonium-239. Uranium-233 has been used as a fuel in several different reactor types, is proposed as a fuel for several new designs, all of which breed it from thorium. Uranium-233 can be bred in either fast reactors or thermal reactors, unlike the uranium-238-based fuel cycles which require the superior neutron economy of a fast reactor in order to breed plutonium, that is, to produce more fissile material than is consumed; the long-term strategy of the nuclear power program of India, which has substantial thorium reserves, is to move to a nuclear program breeding uranium-233 from thorium feedstock. The fission of one atom of uranium-233 generates 197.9 MeV = 3.171·10−11 J. As a potential weapon material, pure uranium-233 is more similar to plutonium-239 than uranium-235 in terms of source, half-life and critical mass.

In 1994, the US government declassified a 1966 memo that states that uranium-233 has been shown to be satisfactory as a weapons material, though it is only superior to plutonium in rare circumstances. It was claimed that if the existing weapons were based on uranium-233 instead of plutonium-239, Livermore would not be interested in switching to plutonium; the co-presence of uranium-232 can complicate the manufacture and use of uranium-233, though the Livermore memo indicates a likelihood that this complication can be worked around. While it is thus possible to use uranium-233 as the fissile material of a nuclear weapon, speculation aside, there is scant publicly available information on this isotope having been weaponized: The United States detonated an experimental device in the 1955 Operation Teapot "MET" test which used a plutonium/233U composite pit. Although not an outright fizzle, MET's actual yield of 22 kilotons was sufficiently below the predicted 33 kt that the information gathered was of limited value.

The Soviet Union detonated its first hydrogen bomb the same year, the RDS-37, which contained a fissile core of 235U and 233U. In 1998, as part of its Pokhran-II tests, India detonated an experimental 233U device of low-yield called Shakti V; the B Reactor and others at the Hanford Site optimized for the production of weapons-grade material have been used to manufacture 233U. Production of 233U invariably produces small amounts of uranium-232 as an impurity, because of parasitic reactions on uranium-233 itself, or on protactinium-233, or on thorium-232: 232Th → 233Th → 233Pa → 233U → 232U 232Th → 233Th → 233Pa → 232Pa → 232U 232Th → 231Th → 231Pa → 232Pa → 232UAnother channel involves neutron capture reaction on small amounts of thorium-230, a tiny fraction of natural thorium present due to the decay of uranium-238: 230Th → 231Th → 231Pa → 232Pa → 232UThe decay chain of 232U yields strong gamma radiation emitters. Thallium-208 is the strongest of these, at 2.6 MeV: 232U 228Th 224Ra 220Rn 216Po 212Pb 212Bi 208Tl 208Pb This makes manual handling in a glove box with only light shielding too hazardous, instead requiring complex remote manipulation for fuel fabrication.

The hazards are significant at 5 parts per million. Implosion nuclear weapons require 232U levels below 50 ppm. Gun-type fission weapons additionally need low levels (1 ppm


Saltasaurini is a tribe of titanosaur sauropods known from the Late Cretaceous of Patagonia, Argentina. The clade was named in 2007 by Leonardo Salgado and José Bonaparte for the "least inclusive clade comprising Neuquensaurus and Saltasaurus", being equivalent to the use of Saltasaurinae in Salgado et al.. Found only in the Campanian to Maastrichtian sediments of the Neuquén Basin, Salgado & Bonaparte decided a more restrictive clade was needed because of the expansion of Saltasaurinae as defined to include far more taxa than it encompassed. Saltasaurini includes the original core of Saltasaurinae: Neuquensaurus, Saltasaurus and Bonatitan, although some studies exclude Bonatitan from the clade

The Trout Inn

The Trout Inn is a historic public house in Lower Wolvercote north of Oxford, close to Godstow Bridge, directly by the River Thames. The pub features in Evelyn Waugh's novel Brideshead Revisited and in Colin Dexter's Inspector Morse series, written and filmed in and around Oxford. For example, it appears in the TV episode "The Wolvercote Tongue". An alternative reality version appears in Philip Pullman's La Belle Sauvage, it appears in the 1997 film version of The Saint. In 2001 the Trout Inn was visited by US President Bill Clinton and his daughter Chelsea, a graduate student at University College, Oxford; the Trout Inn is a Grade II listed building built principally in the 17th century, with some 18th-century alterations and additions. Godstow Bridge, to the south of the inn, consists of two stone arches across the Thames, the northern one dating from medieval times, the southern rebuilt in 1892. Both bridges are Grade II Listed, as is the wooden footbridge at the Trout Inn; the Perch Victoria Arms, Marston The Trout Inn Oxford Restaurant Guide information
