NUCLEAR POWERAn alternative energy resource Where are We?
• Every 22 tonnes of Uavoids emission of 1million tonnes of CO₂.•Global potential of‘cheap ’ uranium foronly 40 years.•Conversion of weaponsgrade HEU to LEUrequired.
India’s Nuclear Program: The Present Status• 12 PHWR & 2 BWR under operation• 4 PHWR and 2 LWR under commission• 2950 MW generation & 3000 MW under commission• Successful experiments with Fast Breeder Test Reactor (FBTR)• Prototype Fast Breeder Reactor (PFBR) for 500MW under construction• Advanced Heavy Water Reactor (AHWR) using (Pu-Th) MOX for 300MW: advanced stage of design approval; construction soon to begin.
Indo-US Nuclear Deal• A watershed in U.S.-India relations and a new aspect to international nonproliferation efforts• Additional Protocol - allows more intrusive IAEA inspections-of its civilian facilities.• India agrees to continue its moratorium on nuclear weapons testing.• India commits to strengthening the security of its nuclear arsenals.• India works toward negotiating a Fission missile cutoff treaty with the US. banning the production of fissile material for weapons purposes. prevent the spread of enrichment and reprocessing technologies to states that dont possess them and to support international nonproliferation efforts• U.S. will be allowed to build nuclear reactors in India and provide nuclear fuel for its civilian energy program. (An approval by the Nuclear Suppliers Group lifting the ban has cleared the way for other countries to make nuclear fuel and technology sales to India.)• IN RETURN eligible to buy U.S. dual-use nuclear technology, including materials and equipment , used to enrich uranium or reprocess plutonium, potentially creating the material for nuclear bombs. receive imported fuel for its nuclear reactors.
Nuclear Medicine Nuclear medicine is the use of radioactive materials in diagnostic or therapeutic procedures, most notably treatments for various forms of cancerDiagnostic and Therapeutic Uses of Radioisotopes• Diagnostic procedures use of relatively small amounts of radioactive materials to facilitate imaging of certain organs to help physicians locate and identify tumors, size anomalies, or other physiological or functional organ problems.• Therapeutic procedures of radioactive materials typically are intended to kill cancerous tissue, reduce the size of a tumor, or reduce pain.Common nuclear medicine procedures that use radioisotopes include the following examples:• Brachytherapy• Gamma Knife• Portable imaging devices in dentistry and podiatry• Bone mineral analysis X-ray• Chemotherapy
Nuclear Weapons A bane to be banned• Can we forget Hiroshima/ Nagasaki destruction?• Testing of Castle Bravo.• Whether its production or testing ,everything has till now proved disastrous.
