Lucas Heights, New South Wales
Lucas Heights is a suburb in southern Sydney, in the state of New South Wales, Australia. It is near to the Royal National Park. Geography It is located 31 kilometres south-west of the Sydney central business district, in the local government area of the Sutherland Shire. Lucas Heights is located on the Woronora River, which flows north into the Georges River. Unusually for a suburb, Lucas Heights does not contain a residential area. The residential area previously part of Lucas Heights was renamed Barden Ridge in 1996 to increase the real estate value of the area, as it would no longer be instantly associated with the High Flux Australian Reactor (HIFAR). History Lucas Heights was named after John Lucas Senior, a flour miller who in 1823 was granted on the 'head of unnamed stream into Georges River'. He built a water-driven mill for grinding corn from the Illawarra farms. Small ships sailed up the coast into Botany Bay, Georges River and the Woronora River. Commercial area ...

Heathcote Road
Heathcote Road is a major arterial road in the south of Sydney, New South Wales, Australia. It runs from Newbridge Road in Liverpool to the Princes Highway in Heathcote. History Heathcote Road was constructed during World War II as a military defence route and a way to bypass the old Illawarra Road which used the ridge lines and a causeway crossing of the Woronora River between Menai and Engadine. Construction began in 1940 and was completed in 1943. Geography Heathcote Road plays a major role in the servicing of traffic travelling between the Illawarra and Western Sydney and also provides access to the Holsworthy Barracks. Other major adjoining roads are the M5 Motorway in Liverpool and the New Illawarra Road at Lucas Heights. Vegetation As its name suggests, the road is generally surrounded by heath, but more often dry eucalyptus ''Eucalyptus'' () is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae.

Local Government In Australia
Local government is the third level of government in Australia, administered with limited autonomy under the states and territories, and in turn beneath the federal government. Local government is not mentioned in the Constitution of Australia, and two referendums in 1974 and 1988 to alter the Constitution relating to local government were unsuccessful. Every state/territory government recognises local government in its own respective constitution. Unlike the two-tier local government system in Canada or the United States, there is only one tier of local government in each Australian state/territory, with no distinction between counties and cities. The Australian local government is generally run by a council, and its territory of public administration is referred to generically by the Australian Bureau of Statistics as the local government area or LGA, each of which encompasses multiple suburbs or localities often of different postcodes; however, stylised terms such a ...

Neutron Radiation
Neutron radiation is a form of ionizing radiation that presents as free neutrons. Typical phenomena are nuclear fission or nuclear fusion causing the release of free neutrons, which then Neutron capture, react with Atomic nucleus, nuclei of other atoms to form new isotopes—which, in turn, may trigger further neutron radiation. Free neutrons are unstable, Free neutron decay, decaying into a proton, an electron, plus an Electron_neutrino#Electron_antineutrino, electron antineutrino. Free neutrons have a mean lifetime of 887 seconds (14 minutes, 47 seconds). Neutron radiation is distinct from alpha radiation, alpha, beta radiation, beta and gamma radiation, gamma radiation. Sources Neutrons may be emitted from nuclear fusion or nuclear fission, or from other nuclear reactions such as radioactive decay or particle interactions with cosmic rays or within particle accelerators. Large neutron sources are rare, and usually limited to large-sized devices such as nuclear reactors or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nuclear Reactor
A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction or nuclear fusion reactions. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. Heat from nuclear fission is passed to a working fluid (water or gas), which in turn runs through steam turbines. These either drive a ship's propellers or turn electrical generators' shafts. Nuclear generated steam in principle can be used for industrial process heat or for district heating. Some reactors are used to produce isotopes for medical and industrial use, or for production of weapons-grade plutonium. , the International Atomic Energy Agency reports there are 422 nuclear power reactors and 223 nuclear research reactors in operation around the world. In the early era of nuclear reactors (1940s), a reactor was known as a nuclear pile or atomic pile (so-called because the graphite moderator blocks of the first reactor were placed into a tall pi ...

Australian Atomic Energy Commission
The Australian Atomic Energy Commission (AAEC) was a statutory body of the Australian government. It was established in 1952, replacing the Atomic Energy Policy Committee. In 1981 parts of the Commission were split off to become part of CSIRO, the remainder continuing until 1987, when it was replaced by the Australian Nuclear Science and Technology Organisation (ANSTO). The Commission head office was in the heritage-listed house Cliffbrook in Coogee, Sydney, New South Wales, while its main facilities were at the Atomic Energy Research Establishment at Lucas Heights, to the south of Sydney, established in 1958. Highlights of the Commission's history included: *Major roles in the establishment of the IAEA and the system of international safeguards. *The construction of the HIFAR and MOATA research reactors at Lucas Heights. *The selection of the preferred tender for the construction of the proposed Jervis Bay Nuclear Power Plant. *The Ranger Uranium Mine joint venture.

Botany Bay
Botany Bay (Dharawal: ''Kamay''), an open oceanic embayment, is located in Sydney, New South Wales, Australia, south of the Sydney central business district. Its source is the confluence of the Georges River at Taren Point and the Cooks River at Kyeemagh, which flows to the east before meeting its mouth at the Tasman Sea, midpoint between the suburbs of La Perouse and Kurnell. The northern headland of the entrance to the bay from the Tasman Sea is Cape Banks and, on the southern side, the outer headland is Cape Solander and the inner headland is Sutherland Point. The total catchment area of the bay is approximately . Despite its relative shallowness, the bay now serves as greater metropolitan Sydney's main cargo seaport, located at Port Botany, with facilities managed by Sydney Ports Corporation. Two runways of Sydney Airport extend into the bay, as do some port facilities. Botany Bay National Park is located on the northern and southern headlands of the bay. ...

Illawarra
The Illawarra is a coastal region in the Australian state of New South Wales, nestled between the mountains and the sea. It is situated immediately south of Sydney and north of the South Coast region. It encompasses the two cities of Wollongong, Shellharbour and the coastal town of Kiama. Wollongong is the largest city of the Illawarra with a population of 240,000, then Shellharbour with a population of 70,000 and Kiama with a population of 10,000. These three cities have their own suburbs. Wollongong stretches from Otford in the north to Windang in the south, with Maddens Plains and Cordeaux in the west. The Illawarra region is characterised by three distinct districts: the north-central district, which is a contiguous urban sprawl centred on Lake Illawarra, the western district defined by the Illawarra escarpment, which leads up to the fringe of Greater Metropolitan Sydney including the Macarthur in the northwest, and to the Southern Highlands region in the southwest ...

Flour Miller
A miller is a person who operates a mill, a machine to grind a grain (for example corn or wheat) to make flour. Milling is among the oldest of human occupations. "Miller", "Milne" and other variants are common surnames, as are their equivalents in other languages around the world (" Melnyk" in Russian, Belorussian & Ukrainian, " Meunier" in French, " Müller" or "Mueller" in German, "Mulder" and "Molenaar" in Dutch, "Molnár" in Hungarian, "Molinero" in Spanish, "Molinaro" or "Molinari" in Italian etc.). Milling existed in hunter-gatherer communities, and later millers were important to the development of agriculture. The materials ground by millers are often foodstuffs and particularly grain. The physical grinding of the food allows for the easier digestion of its nutrients and saves wear on the teeth. Non-food substances needed in a fine, powdered form, such as building materials, may be processed by a miller. Quern-stone The most basic tool for a miller was the quern ...

High Flux Australian Reactor
The High Flux Australian Reactor (HIFAR) was Australia's first nuclear reactor. It was built at the Australian Atomic Energy Commission (later ANSTO) Research Establishment at , Sydney. The reactor was in operation between 1958 and 2007, when it was superseded by the Open-pool Australian lightwater reactor, also in Lucas Heights. Background and operation Based on the DIDO reactor at Harwell in the UK, HIFAR was cooled and moderated by heavy water ( D2O), and the fuel was enriched uranium. There was also a graphite neutron reflector surrounding the core. Like DIDO, its original purpose was nuclear materials testing, using its high neutron flux to give materials intended for use in nuclear power reactors their entire expected lifetime neutron exposure in a relatively short period. HIFAR was used for research, particularly neutron diffraction experiments, production of neutron transmutation doped (NTD) silicon, and for production of medical and industrial radioisotopes.
