A Presentation On Nano toMacro scale nuclear technologyGuided by: Presented by:O. P. Jakhar Gaurav Gunjan Mech. Final year
What is nuclear technology? Nuclear science and technology offers the capability for radical industrial innovations from the nano-to-macro scales and is a field that already impacts over $600 billion in annual worldwide activity. The areas impacted are as diverse as medicine, industrial process control, energy, explosives, materials processing, agriculture, food preservation, sterilisation and non-destructive interrogation for the molecular structure of compounds to use as tracers for transport and the tracking of fluids.
NANOMETER………..(nm) A nanometer is one billionth of a meter (10-9 m). This is roughly ten times the size of an individual atom.
SALIENT FEATURES At atomic and molecular scales, in the length scale of approximately 1 - 100 nanometer range Fundamentally new properties and functions because of their nanoscale structure Ability to control , to see, measure, and manipulate matter on the atomic scale to exploit those properties and functions Ability to integrate those properties and functions into systems spanning from nano- to macro-scopic scales
WORKING OFNANOTECHNOLOGY Atoms are the building blocks for all matter in our universe. Atoms and molecules stick together because they have complementary shapes that lock together, or charges that attract. Just like with magnets, a positively charged atom will stick to a negatively charged atom. Every atom has a exhibits different property at various conditions The goal of nanotechnology is to manipulate atoms individually and place them in a pattern to produce a desired structure.
COMPUTERS1. Each logic elements made from a few atoms2. Mass storage device in size of a sugar cube3. Tiny nano-engineered ferroelectric crystals could realize of creating nonvolatile random access memory (NVRAM).4. Cool chips
MEDICINE Fluids of nano particles Slow down ageing process No scar surgeries Artificial limbs
Cancer and HIVNano filters- capable of absorbingvirusesNano catalyst – improves efficiency ofa reaction.
FEAR Nuclear and atomic bombs can have different dimensions Cloning and miniaturization Nano medicine- worrying factor!
Macro nuclear technology•The larger of two nuclei present in ciliate protozoans , which controlsnonreproductive functions of the cell,such as metabolism•Macro refers to large applications .•It is basically employed in nuclearpower plant.

Nuclear power in India: India has a flourishing and largely indigenous nuclear power program and expects to have 20,000 MWe nuclear capacity on line by 2020 and 63,000 MWe by 2032. It aims to supply 25% of electricity from nuclear power by 2050. Because India is outside the Nuclear Non- Proliferation Treaty due to its weapons program, it was for 34 years largely excluded from trade in nuclear plant or materials, which has hampered its development of civil nuclear energy until 2009.
Due to these trade bans and lack ofindigenous uranium, India has uniquelybeen developing a nuclear fuel cycle toexploit its reserves of thorium. Now, foreign technology and fuel areexpected to boost Indias nuclearpower plans considerably. All plantswill have high indigenous engineeringcontent. India has 20 nuclear power plant and 5are under construction.
