How Nuclear Energy Waste Disposed & Managed in Indian Atomic Energy Centers
As part of the Theme of February.I am bring forward a very interesting post which I posted on 12/17/09.Please enjoy reading the article.
In India, Radioactive waste management facilities are located at seven DAE (Department of Atomic Energy) centers, namely Trombay, Tarapur, Kalpakkam, Rawatbhata, Narora, Kakrapar and Kaiga. These facilities have been designed, constructed and commissioned based on the research and development programme which was initiated four decades ago alongwith the inception of nuclear energy programmed in the country. The facilities incorporate waste management systems for treatment and disposal of radioactive waste generated in the form of gas, liquid and solid.
Radioactive gaseous waste is decontaminated at source by treatment processes like demisters, adsorption, filtration through high efficiency particulate air filters etc and after monitoring, discharged through tall stacks for further dispersion.
Radioactive liquid and solid waste is categorized as low, intermediate and high level radioactive waste based on the activity content. The waste is segregated and provided treatment to retain bulk of the radioactivity.
Low & intermediate level radioactive liquid wastes are subjected to treatments such as chemical, ion exchange, evaporation and membrane separation. The bulk of the radioactivity is removed and conditioned in a suitable matrix like cement. The solidified waste is packaged in suitable containers and are stored/disposed in near surface disposal facilities. These facilities are designed on multi-barrier principal and have elaborate monitoring and surveillance provisions. The treated effluents are monitored and discharged well within the authorized limits to the environment.
High level waste is vitrified into borosilicate glass matrix and encapsulated in steel canisters. These canisters are later stored for interim period in specially made air cooled facilities.
All these Adequate arrangements have been made for the disposal of nuclear energy waste in the country by DAE (Department of Atomic Energy)

National Entrance Screening Test | NEST 2010 for admission into five year integrated Masters program
National Entrance Screening Test (NEST) 2010 is the entrance test for students seeking admission to the 5-year integrated Masters programme at the University of Mumbai – Department of Atomic Energy Centre for Excellence in Basic Sciences (UM-DAE CBS) Mumbai, National Institute of Science Education and Research (NISER), Bhubaneswar, and Integrated Science Education and Research Centre (ISERC), Visva-Bharati, Santiniketan.
Know more about the institutes....
UM-DAE Centre for Excellence in Basic Sciences (CBS), Mumbai
(http://cbs.ac.in/).
(http://visva-bharati.ac.in/).
All the institutes have residential campuses with suitable accommodation and boarding facilities. The academic programmes of all the institutes have a balanced semester-based course structure with continuous assessment within a flexible seamless curriculum designed to emphasize the interdisciplinary nature of science in the 21st century. The curriculum vigorously seeks to inculcate exploration, innovation and research so as to develop a pool of talented and motivated scientists for the country.
Meritorious candidates enrolled at CBS or NISER, whose performance at the end of the programme is above a certain threshold, may be permitted to appear directly before the selection committee of BARC for admission to BARC's training school. All candidates enrolled at CBS or NISER will receive a scholarship equivalent to the INSPIRE fellowships, amounting to Rs. 5,000/- per month and other suitable benefits. Candidates enrolled at Visva-Bharati will be eligible to apply for INSPIRE fellowships.
Who Can Apply?
Students who have passed the Class XII (or equivalent) qualifying examination in 2008 or 2009 or are appearing in 2010 from any recognized Board of education in India and have secured an aggregate of at least 60% marks (or equivalent grade) are eligible to apply. For Scheduled Castes (SC), Scheduled Tribes (ST) candidates and for Persons with Disability (PD), the minimum marks requirement is 55%. (Where only “Letter” grade is given by a Board, a certificate from the Board specifying equivalent percentage marks will be required. In the absence of such a certificate the decision of the Admissions Committee of the concerned institutions will be final.)Age Limit: General category candidates and Candidates belonging to Other Backward Castes (OBC) born on or after 01 Oct. 1985 are eligible to apply. For SC/ST/PD candidates the age limit is relaxed by 5 years. In any case, the eligibility criterion mentioned above must be satisfied.
Number of Seats and Reservation: This year (2010), the number of seats is 60 at NISER, 30 at UM-DAE CBS and 21 at ISERC. There will be reservations as per Government norms. Further details are given on the websites of NISER (http://niser.ac.in) UM-DAE CBS (http://cbs.ac.in) and ISERC (http://visva-bharati.ac.in).
Application Fee: Application fee for appearing in NEST is Rs. 500/- for male general category and male OBC candidates. For male SC/ST/PD candidates and all female candidates the amount is Rs. 250/-. The application fee should be sent to Chief Coordinator at the address mentioned below in the form of a demand draft / postal order in favour of 'NEST-2010' payable at Mumbai.
