Vaalputs
Vaalputs is the only South African radioactive waste-disposal facility, called the ''Vaalputs Radioactive Waste Disposal Facility'', operated by NECSA. The facility is located about 100 km south-east of Springbok, in the Northern Cape. It covers an area of approximately 10,000 hectare, measuring 16,5 km from east to west and 6,5 km from north to south at its narrowest point. Approximately 1,000 hectare is occupied by sites developed for low- and intermediate-level waste, an interim spent nuclear fuel storage facility, housing, roads, power lines and an airstrip. Vaalputs lies between the Namaqualand in the west and the Bushmanland in the east. During 1978 a programme to select a suitable site for the disposal of nuclear waste was commenced over large parts of South Africa. The programme leader had to keep a variety of socio-economic and geology related parameters in mind. Pioneer investigations indicated that the Northern Cape was the most feasible area. Supplemen ...

South African Nuclear Energy Corporation
The South African Nuclear Energy Corporation (Necsa) was established as a public company by the Republic of South Africa Nuclear Energy Act in 1999 and is wholly owned by the State. The name is correctly indicated above, although the sequence of letters in the acronym may be taken as suggesting that the name should be the "Nuclear Energy Corporation of South Africa". Operations Necsa replaced the country's Atomic Energy Corporation. Apart from several ancillary functions, the main functions of Necsa are to undertake and promote research and development in the field of nuclear energy and related technologies; to process and store nuclear material and other restricted material; and to co-ordinate with other organisations in matters falling within these spheres. Apart from its main operations at Pelindaba, Necsa also operates the Vaalputs radioactive waste disposal facility. The corporation also serves the State's other nuclear institutional obligations.

Bushmanland, Northern Cape
Bushmanland is an arid area south of the Orange River and west of Kenhardt and east of Springbok (Namaqualand) in the Northern Cape, South Africa. It includes the towns of Pofadder and Aggeneys, and places such as Namies and Bosluis Pan. Extensive plains are dotted with inselbergs like the Gamsberg. Bushmanland is an arid area inland from Namaqualand. It is probably the most inhospitable area in South Africa, arid and largely with infertile soil and highly saline groundwater. Its wildlife, however, both fauna and flora, though sparse, are full of interest. Although the veld is too arid to bloom like that of the West Coast of Namaqualand, even when there is some spring rain, what does appear is highly unusual and often hauntingly beautiful. Vaalputs, a nuclear waste repository, has been sited between Bushmanland and Namaqualand, and acts as a ''de facto ''De facto'' ( ; , "in fact") describes practices that exist in reality, whether or not they are officially recognized by ...

South Africa
South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; and to the east and northeast by Mozambique and Eswatini. It also completely enclaves the country Lesotho. It is the southernmost country on the mainland of the Old World, and the second-most populous country located entirely south of the equator, after Tanzania. South Africa is a biodiversity hotspot, with unique biomes, plant and animal life. With over 60 million people, the country is the world's 24th-most populous nation and covers an area of . South Africa has three capital cities, with the executive, judicial and legislative branches of government based in Pretoria, Bloemfontein, and Cape Town respectively.

Radioactive Waste
Radioactive waste is a type of hazardous waste that contains radioactive material. Radioactive waste is a result of many activities, including nuclear medicine, nuclear research, nuclear power generation, rare-earth mining, and nuclear weapons reprocessing. The storage and disposal of radioactive waste is regulated by government agencies in order to protect human health and the environment. Radioactive waste is broadly classified into low-level waste (LLW), such as paper, rags, tools, clothing, which contain small amounts of mostly short-lived radioactivity, intermediate-level waste (ILW), which contains higher amounts of radioactivity and requires some shielding, and high-level waste (HLW), which is highly radioactive and hot due to decay heat, so requires cooling and shielding. In nuclear reprocessing plants about 96% of spent nuclear fuel is recycled back into uranium-based and mixed-oxide (MOX) fuels. The residual 4% is minor actinides and fission products the latter of w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Springbok, Northern Cape
Springbok is the largest town in the Namaqualand area in the Northern Cape province of South Africa. It was called Springbokfontein until 1911, when it was shortened to Springbok. Springbok is located on the N7 road (South Africa), N7 national route (South Africa), national route which connects the Cape with Namibia, and at the western end of the N14 road (South Africa), N14, which connects it with Upington and Pretoria. It is the main town of the Nama Khoi Local Municipality, which also includes a number of surrounding towns such as Okiep and Nababeep. The town lies at an elevation of in a narrow valley between the high granite domes of the ''Klein Koperberge'' (Small Copper Mountains). This name gives away the reason for the early settlement which gradually turned into a major commercial and administrative centre for copper mining operations in the region. While the town initially developed rapidly, this slowed when rich copper deposits were discovered in Okiep. As the main sour ...

Low Level Waste
Low-level waste (LLW) or Low-level radioactive waste (LLRW) is nuclear waste that does not fit into the categorical definitions for intermediate-level waste (ILW), high-level waste (HLW), spent nuclear fuel (SNF), transuranic waste (TRU), or certain byproduct materials known as 11e(2) wastes, such as uranium mill tailings. In essence, it is a definition by exclusion, and LLW is that category of radioactive wastes that do not fit into the other categories. If LLW is mixed with hazardous wastes as classified by RCRA, then it has a special status as mixed low-level waste (MLLW) and must satisfy treatment, storage, and disposal regulations both as LLW and as hazardous waste. While the bulk of LLW is not highly radioactive, the definition of LLW does not include references to its activity, and some LLW may be quite radioactive, as in the case of radioactive sources used in industry and medicine. LLW includes items that have become contaminated with radioactive material or have become ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spent Nuclear Fuel
Spent nuclear fuel, occasionally called used nuclear fuel, is nuclear fuel that has been irradiated in a nuclear reactor (usually at a nuclear power plant). It is no longer useful in sustaining a nuclear reaction in an ordinary thermal reactor and depending on its point along the nuclear fuel cycle, it may have considerably different isotopic constituents. The term "fuel" is slightly confusing, as it implies a combustion of some type, which does not occur in a nuclear power plant. Nevertheless, this term is generally accepted. Nature of spent fuel Nanomaterial properties In the oxide fuel, intense temperature gradients exist that cause fission products to migrate. The zirconium tends to move to the centre of the fuel pellet where the temperature is highest, while the lower-boiling fission products move to the edge of the pellet. The pellet is likely to contain many small bubble-like pores that form during use; the fission product xenon migrates to these voids. Some of this xeno ...

Provinces Of South Africa
South Africa is divided into nine provinces. On the eve of the 1994 general election, South Africa's former homelands, also known as Bantustans, were reintegrated, and the four existing provinces were divided into nine. The twelfth, thirteenth and sixteenth amendments to the Constitution of South Africa changed the borders of seven of the provinces. History The Union of South Africa was established in 1910 by combining four British colonies: the Cape Colony, the Natal Colony, the Transvaal Colony and the Orange River Colony (the latter two were, before the Second Boer War, independent republics known as the South African Republic and the Orange Free State). These colonies became the four original provinces of the Union: Cape Province, Transvaal Province, Natal Province and Orange Free State Province. Segregation of the black population started as early as 1913, with ownership of land by the black majority being restricted to certain areas totalling about 13% of the country. ...
