Geography
editIt 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
editLucas Heights was named after John Lucas Senior, a flour miller who in 1823 was granted 150 acres (0.6 km2) 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.[2]
Commercial areas
editLucas Heights has become notable as the site of the Australian Nuclear Science and Technology Organisation’s (ANSTO) main research establishment, originally built by the Australian Atomic Energy Commission and home to the historic HIFAR research reactor.
HIFAR was shut down in January 2007 and superseded by the OPAL research reactor. OPAL consists of leading neutron radiation facilities and attracts international scientists as its staff members and many hundreds of third-party users. In 2005, Australian police suggested the HIFAR reactor was a possible target for a foiled terrorist bomb attack.[3]
Spent fuel from the OPAL research reactor is transported to Port Kembla, then exported to France for reprocessing.[4]
The non-governmental Australian Institute of Nuclear Science and Engineering (AINSE) also has its headquarters at Lucas Heights.[5]
Lucas Heights also hosts a (non-nuclear) waste management facility, which was for many years a major disposal site for sanitary carters.
Climate
editDue to its elevation, Lucas Heights is one of the few places in Sydney that has a borderline Oceanic (Cfb) and a Humid subtropical climate (Cfa).
