Challenges ahead1. How to reduce the “GAP” between demand and supply of natural uranium ?

a) Reducing demand:i. Increasing fuel burnup by optimizing fuel design and micro structureii. Reprocessing spent LWR & PHWR fuels - mono-recycling plutonium in LWRs

/ PHWRs and re-enriching and reusing reprocessed uraniumiii. Direct Utilization of spent PWR fuel In CANDU reactors - DUPIC processiv. Reprocessing of spent fuel and multiple recycling of plutonium in combination

with depleted uranium in fast reactorsv. Lowering “tail assay” in enrichment plant

b) Increasing Supply from conventional and unconventional sources:i. Augmenting capacity of operating mines and mills and improving recoveryii. Opening new mines and millsiii. Developing economically viable process flow sheets for recovering uranium

as by-product from unconventional sources (eg: phosphate rocks, coal ash, monazite, seawater etc)

Challenges ahead

2. How to reduce the ‘GAP’ between uranium in ground and Yellow Cake in can?a) By increasing uranium resource base by adapting

advanced geophysical and geochemical methods b) By prioritizing uranium mine and mill licensing process

thereby reducing the time needed for licensingc) By improving uranium recovery from mine and mill

through improved mining methods, leaching techniques and purification process

d) By adapting In situ leach mining, mainly for porous sandstone type deposits

Challenges ahead

3. Issues related to radiological and mine safety and environmental protection and adapting leading practices in uranium production cycle (encouraging UPSAT)

4. Issues related to “Social Licensing”5. Issues related to ageing and retiring human

resource and shortage of experts
