The Atomic Energy Board was still in existence from 1 January to 30 June 1982, A report on the activities of the Licensing Branch, which was transferred to the Atomic Energy Corporation of South Africa Limited only on 1 July 1982, is therefore also included in this review. Because MINTEK at present bears responsibility for uranium extraction, a short report on extrac- tion metallurgy from MINTEK's annual report for 1982 is also included in this review. On 1 April 1982 the Life Sciences Division of the former AEB was transferred to the University of Pretoria. Because it is now the NUCOR Institute for Life Sciences and is financed by NUCOR, a short report on the activities of the Institute also appears in this review. J.P. Hugo MANAGING DIRECTOR PELINDABA 83-12-01 NUCOR REVIEW KERNKOR-OORSIG Pursuant to the reorganisation of state-funded nuclear activities Die herorganisasie van staatsgefinansierde kernbedrywighede in South Africa with effect from July 1982, the Annual Report of in Suid-Afrika met ingang van Julie 1982, het meegebring dat the former Atomic Energy Board was discontinued.' die Jaarverslag van die gewese Raad op Atoomkrag gestaak is. In order to ensure that research and development work of the Om te verseker dat belanghebbende partye, soos in die verlede, former Atomic Energy Board, which is now the responsibility of steeds oor die navorsings- en ontwikkelingswerk van die the Nuclear Development Corporation of SA (Pty) Ltd (NUCOR) voormalige Raad op Atoomkrag, tans die verantwoordelikheid is. as in the past, still made known to interested parties, the van die Kernontwikkelingskorporasie van SA (Edms) Bpk., Chairman of NUCOR, Dr. J.W.L de Villiers, has pleasure in (KERNKOR), ingelig word, het die Voorsitter van KERNKOR. announcing the publication of the first annual NUCOR REVIEW, dr J.W.L de Villiers, die genoeë om aan te kondig dat die eerste covering the fifteen month period from January 1982 to March jaarlikse KERNKOR-OORSIG wat die vyftien maande van 1983. 1 Januarie 1982 tot 31 Maart 1983 dek, verskyn het. A highlight of this period was the announcement by the Minister 'n Hoogtepunt van hierdie tydperk was die aankondiging deur of Mineral and Energy Affairs that a site in the Namaqualand die Minister van Mineraal- en Energiesake dat KERNKOR 'n District was to be developed and operated by NUCOR as the terrein in die Distrik Namakwaland as die nasionale bewaarplek national depository for medium- and low-active nuclear waste. vir medium- en laagaktiewe kernafval sou ontwikkel en bedryf.

In the case of From 1 January to 30 June 1982 the activities of the former asparagus, trials showed that radurisation at doses of 1 to Atomic Energy Board (AEB) continued unabated. Under the 1,5 kGy leads to a dramatic extension of the shelf life of fresh Nuclear Energy Act 1982 (Act 92 of 1982), the Atomic Energy white asparagus and gives it a more acceptable taste. Further Corporation of South Africa Limited (AEC) was established success was achieved with the irradiation of strawberries, 210 with effect from 1 July 1982.
