Marwah, BARC - Member Secretary The National Symposium on Uranium Technology was held at BARC, Bombay during Dec. 13-15,1989 under the auspices of Engi­ neering Science Committee of Board of Research in Nuclear Science, Department, of Atomic. Energy. In the context of expanding nuclear power programme in India, the need for production of large quantity of uranium fuel from indigeneous'resources hardly needs any elaboration. After three decades of experience in :this area, it is thus appropriate to pool together the expertise and experience gained in the country during this period in various aspects of uranium technol­ ogy like exploration, mining, ore processing, refining and con­ version to. oxide and metal. This symposium has provided an opportunity to the uranium technologists to interact and exchange their experience and plan future strategies. Being the first symposium on this toppic the response has been excellent as evidenced by the extensive participation and contribution of papers covering almost all aspects of uranium technology. Altogether 69 papers, including invited lectures have been presented and the proceedings, have been brought out in two volumes. It is our hope that this technical coverage of the pro­ ceedings and panel discussion would serve as a valuable reference material for uranium technologists in the coming years; We wish to record our sincere thanks to the members of the organising and various other committees, authors of invited' lectures, and contributed papers, and panel members for making it possible to bring out this proceedings. The cooperation extended by Head, Library and Information Division, BARC is gratefuly acknowledged. TECHNICAL COMMITEE CONTENTS INAUGURAL SESSION Introductory Remarks by Shri S.

  • Self-Reported Morbidities Among Tribal Workers Residing Adjacent the Turamdih Uranium Mine and Mill in Jharkhand, India
    Self-Reported Morbidities among Tribal workers Residing adjacent the Turamdih Uranium Mine and Mill in Jharkhand, India. Ashwani Kumar1, K. C. Das2 1Monitoring and Evaluation Specialist, FP Track20 Avenir Health, India Email: [email protected] Contact No: 91+9969789292 ORCID ID: 0000-0002-5515-2840 2Professor, Department of Migration and Urban Studies, International Institute for Population Sciences, Mumbai, India – 400088 Email: [email protected] Abstract The study was conducted among 411 main workers of tribal communities, aged 15-59 years, residing surrounding hazardous uranium tailing pond of Turamdih Uranium mine in Jharkhand, India. The survey was conducted between January and June 2016. The objective of the study was to explore the differential morbidities among mineworkers and non- mineworkers and the association of the morbidity with various socio-demographic factors. Chi-square test, and binary logistic regression were used for data analysis. The results indicate that the prevalence of digestive problems, skin diseases, cancerous diseases, and urinary dysfunction was significantly higher among the Uranium mine-workers than the non-mineworkers. The main workers living within a range of 2 km from the tailing pond being more likely to suffer digestive problems (OR=1.57; 95% CI, 0.94–2.60) and respiratory illnesses (OR=1.89; 95% CI, 1.06–3.37) than those living further away. The findings have important program and policy implications related to safety measures, nuclear regulation acts, and resettlement of tribal victims. Keywords: uranium mining, radiation, mineworkers, morbidities, tailing pond, distance Introduction In view of alternate sources of efficient energy generation, Uranium has gained enormous global importance driven by its medical, military and civil applications, albeit with potential safety and environmental legacies.(1) In India, Uranium Corporation of India (UCIL), founded in 1967 under the Department of Atomic Energy, is responsible for the mining and milling of uranium ore.

  • Uranium Mining and Heap Leaching in India and Related Safety Measures — a Case Study of Jajawal Mines
    XA0103131 URANIUM MINING AND HEAP LEACHING IN INDIA AND RELATED SAFETY MEASURES — A CASE STUDY OF JAJAWAL MINES V.P. SAXENA Atomic Minerals Division, Department of Atomic Energy, Uniara Garden, Jaipur S.C. VERMA Atomic Minerals Division, Department of Atomic Energy Civil Lines, Nagpur India Abstract Exploration and exploitation of uranium involves drilling, mining, milling and extraction processes including heap leaching in some cases. At the exploration stage, the country's laws related to statutory environmental clearance covering forest and sanctuaries or Coastal Regulatory Zones (CRZ) are: equally applicable for atomic minerals. At the developmental mining or commercial exploitation stage in addition to the environmental impact assessment, the provisions of Atomic Energy (working of Mines, Minerals and handling of Prescribed Substances) Rules 1984 are also to be followed which covers radiation monitoring, pollution control and other safety measures which are enforced by licensing authorities and the Atomic Energy Regulatory Board (AERB) of India. In India, Jaduguda, Bhatin, Narwapahar in Singhbhum Thrust Belt (STB), Asthota and Khiya in Siwaliks, Domiasiat in Cretaceous sandstones, Bodal and Jajawal in Precambrian crystallines, are some of the centres, where mining has been carried out up to various underground levels. Substantial amount of dust and radon gas are generated during mining and milling operations. Though uranium mining is considered as hazardous for contamination by radionuclides, it is observed that many non-uranium mines have registered up to 100 mWL radon concentration, e.g. copper mines in STB area show up to 900 mewl in a few cases. Compared to this the Uranium mines in India have not shown any increase over the limits prescribed by AERB.

  • Radiological Impact Assessment in Bagjata Uranium Deposit: a Case Study
    RADIOLOGICAL IMPACT ASSESSMENT IN BAGJATA URANIUM DEPOSIT: A CASE STUDY By A. K. SARANGI ***, S. C. BHOWMIK ****** & V. N. JHA *** Abstract The uranium ore mining facility, in addition to the desirable product, produces wastes in the form of environmental releases or effluents to air, water and soil. The toxicological and other (non-radiological) effects are generally addressed in EIA / EMP studies as per MOEF guidelines. Since the uranium ore is radioactive, it is desirable to conduct a study on radiological effects considering the impacts of radiological releases to the environment. Before undertaking the commercial mining operations at Bagjata uranium deposit in the Singhbhum east district of Jharkhand, pre-operational radiological base line data were generated and a separate study on radiological impact on various environmental matrices was conducted inline with the International Atomic Energy Agency’s laid out guidelines. The paper describes the philosophy of such studies and the findings that helped in formulating a separate environmental management plan. INTRODUCTION: Uranium is widely distributed in the earth’s crust with an average abundance of two parts per million (ppm). Rocks containing uranium bearing minerals with average grades of about 1000 ppm are usually mined by conventional open pit or underground methods depending on the geological condition of the ore, such as deposit size, ore grade, depth and ground condition. The underground operation produces less waste rock than open pit mining. In some cases like Australia and USA where average grades of uranium are between 100 to 1000 parts per million, uranium is recovered as a by-product of other mineral commodities.
